Description
本発明は、新規な塗装方法に関するものである。本発明は、主に建築物や土木構造物等に対して適用することができる。 The present invention relates to a novel coating method. The present invention can be applied mainly to buildings, civil engineering structures, and the like.
従来、建築物や土木構造物等においては、その表面に種々の模様が付与されている。このうち、多彩模様塗料を用いた塗装によれば、一回の塗装で複数色の色粒が混在した模様を得ることができる。多彩模様塗料は、ＪＩＳ Ｋ５６６７（２００２）「多彩模様塗料」に規定されており、塗料を構成する分散媒と着色粒子の組み合わせによって、水中油型（Ｏ／Ｗ型）、油中水型（Ｗ／Ｏ型）、油中油型（Ｏ／Ｏ型）及び水中水型（Ｗ／Ｗ型）の４種類に分類される。 Conventionally, various patterns are given to the surface of a building or a civil engineering structure. Among these, the painting using the multicolored paint can obtain a pattern in which a plurality of color particles are mixed in one painting. The multicolored paint is defined in JIS K5667 (2002) “Multicolored paint”. Oil-in-water type (O / W type), water-in-oil type (W / O type), oil-in-oil type (O / O type), and water-in-water type (W / W type).
このような多彩模様塗料の塗装においては、予め別の塗材を塗付し下地を形成しておくことによって、意匠性を高めることもできる。例えば、特許文献１（特開昭６２−８７２８５号公報）には、凹凸状に形成せしめた下塗り層の上に、多彩模様塗料を塗付することによって、立体感に富んだ装飾性仕上げを得ることが記載されている。また、特許文献２（特開２００２−２６３５６１号公報）には、部分的に色調が異なる下塗り塗膜の上に、多彩模様塗料を塗付する方法が記載されている。当該特許文献２では、陰影感、深み感等を有する意匠性が得られることが記載されている。 In the application of such a colorful pattern paint, design properties can be improved by applying a different coating material in advance to form a base. For example, in Patent Document 1 (Japanese Patent Laid-Open No. 62-87285), a decorative finish rich in three-dimensional effect is obtained by applying a multicolored paint on an undercoat layer formed in an uneven shape. It is described. Patent Document 2 (Japanese Patent Laid-Open No. 2002-263561) describes a method of applying a multicolored paint on an undercoat film having a partially different color tone. In Patent Document 2, it is described that design properties having a feeling of shading, a feeling of depth, and the like can be obtained.
しかしながら、上記特許文献に記載の方法において、多彩模様塗料によって形成される色粒は、被塗面全体に亘りほぼ均一な状態で変化に乏しく、美観性向上の点ではまだ改善の余地がある。 However, in the method described in the above-mentioned patent document, the color particles formed by the multicolor paint are scarcely changed in a substantially uniform state over the entire surface to be coated, and there is still room for improvement in terms of improving aesthetics.
本発明は、上述のような問題点に鑑みなされたものであり、塗装仕上げによる模様面形成において、その美観性を高める新規な方法を提供することを目的とするものである。 The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a novel method for improving the aesthetics in forming a pattern surface by paint finishing.
本発明者は、上記目的を達成するため鋭意検討を行った結果、骨材含有塗材を用いて凹凸領域と平坦領域とが混在する下地面を形成した後、当該下地面に対して、分散媒中に着色塗料の粒状物が分散した上塗材を塗付する方法に想到し、本発明を完成させるに到った。
すなわち、本発明は以下の特徴を有するものである。
As a result of intensive studies to achieve the above object, the present inventor formed a base surface in which uneven regions and flat regions are mixed using an aggregate-containing coating material, and then dispersed with respect to the base surface. The inventors have conceived a method of applying a top coating material in which particles of colored paint are dispersed in a medium, and have completed the present invention.
That is, the present invention has the following characteristics.
１．基材に対し、
（１）平均粒子径０．１ｍｍ以上５ｍｍ以下の骨材を含む骨材含有塗材を１種以上用いて、骨材による凹凸が形成された凹凸領域と、当該凹凸領域よりも凹凸が平坦化された平坦領域とが混在した下地面を形成する工程、
（２）当該下地面に対し、分散媒中に着色塗料の粒状物が分散した上塗材を塗付する工程、
を行うことを特徴とする模様面の形成方法。
２．前記工程（１）では、
平均粒子径０．１ｍｍ以上５ｍｍ以下の骨材を含む骨材含有塗材を１種以上塗付し、
その塗面の一部の領域において、骨材を埋没させる処理、骨材を露出させる処理、及び骨材を除去する処理から選ばれる１種以上の処理を施すことにより、

本発明によれば、平坦領域では比較的大きな色粒によって模様が形成され、凹凸領域では比較的小さな色粒によって模様が形成される。そのため、最終的な仕上面において視覚的変化が生じ、美観性を高めることができる。 According to the present invention, a pattern is formed with relatively large color particles in the flat region, and a pattern is formed with relatively small color particles in the uneven region. Therefore, a visual change occurs in the final finished surface, and aesthetics can be enhanced.
以下、本発明を実施するための最良の形態について説明する。 Hereinafter, the best mode for carrying out the present invention will be described.
本発明は、主に、建築物の内外壁面、天井、床等、あるいは土木構造物の表面等に適用することができる。このような部位を構成する基材としては、例えば、コンクリート、モルタル、サイディングボード、押出成形板、石膏ボード、パーライト板、合板、プラスチック板、金属板、木工板、ガラス、煉瓦、陶磁器タイル等の各種基材が挙げられる。
これら基材は、何らかの表面処理（フィラー処理、サーフェーサー処理、シーラー処理等）が施されたものや、予め着色塗料等で着色されたものでもよく、既に塗膜が形成されたものや、壁紙が貼り付けられたものであってもよい。
The present invention can be applied mainly to the inner and outer wall surfaces, ceilings, floors, etc. of buildings, or the surface of civil engineering structures. As a base material constituting such a part, for example, concrete, mortar, siding board, extrusion board, gypsum board, pearlite board, plywood board, plastic board, metal board, wood board, glass, brick, ceramic tile, etc. Various base materials are mentioned.
These base materials may have been subjected to some surface treatment (filler treatment, surfacer treatment, sealer treatment, etc.), or may be pre-colored with a colored paint or the like. It may be affixed.
本発明では、工程（１）において、まず上記基材に対し、平均粒子径０．１ｍｍ以上５ｍｍ以下の骨材を含む骨材含有塗材を塗付する。
この塗材における骨材としては、平均粒子径が上記範囲内のものであれば材質は特に限定されず、例えば、寒水石、珪砂、砂利、ガラスビーズ、樹脂ビーズ、金属粒、あるいは岩石、ガラス、陶磁器、貝殻、焼結体、コンクリート、モルタル、プラスチック、ゴム等の破砕品等が使用できる。これらは、着色処理が施されたものであってもよい。
骨材の平均粒子径が０．１ｍｍよりも小さい場合は、凹凸領域における凹凸の程度が不十分となり、本発明の効果が得られ難くなる。骨材の平均粒子径が５ｍｍを超える場合は、塗装作業等に支障をきたすおそれがあり、実用的ではない。本発明では、特に、平均粒子径０．１５ｍｍ以上３ｍｍ以下（好ましくは０．２ｍｍ以上２ｍｍ以下）の骨材を含む骨材含有塗材が好適である。
なお、骨材の平均粒子径は、ＪＩＳ Ｚ８８０１−１：２０００に規定される金属製網ふるいを用いてふるい分けを行い、その重量分布の平均値を算出することによって得られる値である。
In the present invention, in the step (1), first, an aggregate-containing coating material including an aggregate having an average particle diameter of 0.1 mm or more and 5 mm or less is applied to the substrate.
As the aggregate in this coating material, the material is not particularly limited as long as the average particle diameter is within the above range. For example, cryolite, quartz sand, gravel, glass beads, resin beads, metal particles, rocks, glass Ceramics, shells, sintered bodies, concrete, mortar, plastic, rubber and other crushed products can be used. These may be subjected to a coloring treatment.
When the average particle diameter of the aggregate is smaller than 0.1 mm, the degree of unevenness in the uneven region becomes insufficient, and it becomes difficult to obtain the effects of the present invention. When the average particle diameter of the aggregate exceeds 5 mm, there is a risk of hindering the painting work and the like, which is not practical. In the present invention, an aggregate-containing coating material containing an aggregate having an average particle diameter of 0.15 mm to 3 mm (preferably 0.2 mm to 2 mm) is particularly suitable.
In addition, the average particle diameter of aggregate is a value obtained by performing sieving using a metal net sieve specified in JIS Z8801-1: 2000 and calculating the average value of the weight distribution.
本発明における骨材含有塗材は、樹脂成分を含むベース塗材と、上記骨材との混合物である。骨材含有塗材における骨材の含有比率は、ベース塗材の固形分１００重量部に対し、通常１０〜２０００重量部、好ましくは３０〜１０００重量部、より好ましくは５０〜５００重量部程度である。骨材の含有比率がこのような範囲内であれば、後の工程において凹凸領域と平坦領域が形成しやすくなり好適である。 The aggregate-containing coating material in the present invention is a mixture of a base coating material containing a resin component and the above-mentioned aggregate. The aggregate content ratio in the aggregate-containing coating material is usually about 10 to 2000 parts by weight, preferably about 30 to 1000 parts by weight, more preferably about 50 to 500 parts by weight with respect to 100 parts by weight of the solid content of the base coating material. is there. If the content ratio of the aggregate is within such a range, the uneven region and the flat region are easily formed in a later step, which is preferable.
ベース塗材における樹脂成分は、結合材として作用するものであり、本発明では水分散性樹脂及び／または水溶性樹脂が好適である。樹脂の種類としては、例えば、アクリル樹脂、ウレタン樹脂、エポキシ樹脂、塩化ビニル樹脂、酢酸ビニル樹脂、シリコン樹脂、フッ素樹脂、ポリビニルアルコール、セルロース誘導体等、あるいはこれらの複合物等が挙げられる。このような樹脂成分は、塗膜形成後に架橋反応を生じる性質を有するものであってもよい。 The resin component in the base coating material acts as a binder, and in the present invention, a water-dispersible resin and / or a water-soluble resin is suitable. Examples of the resin include acrylic resins, urethane resins, epoxy resins, vinyl chloride resins, vinyl acetate resins, silicon resins, fluororesins, polyvinyl alcohol, cellulose derivatives, and composites thereof. Such a resin component may have a property of causing a crosslinking reaction after the coating film is formed.
上記ベース塗材としては、樹脂成分に加え、平均粒子径０．１ｍｍ未満の粉粒体を含むものが好適である。このような粉粒体を用いることで、上塗材塗装後の着色粒子の滲み等が抑制され、美観性向上の点で好適である。この効果は、下地面の表層においてマイクロオーダー以下の微細な凹凸等が形成されることが有効に作用しているものと推測される。
このような粉粒体としては、各種体質顔料、着色顔料等が使用できる。具体的に、体質顔料としては、例えば、重質炭酸カルシウム、炭酸カルシウム、軽微性炭酸カルシウム、硫酸バリウム、クレー、カオリン、陶土、チャイナクレー、タルク、沈降性硫酸バリウム、炭酸バリウム、ホワイトカーボン、珪藻土、中空ビーズ等が挙げられる。

As said base coating material, what contains the granular material with an average particle diameter of less than 0.1 mm in addition to a resin component is suitable. By using such a granular material, bleeding of colored particles after the coating of the top coat material is suppressed, which is preferable in terms of improving aesthetics. It is presumed that this effect is effectively due to the formation of fine irregularities of the order of micrometer or less in the surface layer of the base surface.
As such a granular material, various extender pigments, colored pigments and the like can be used. Specific examples of extender pigments include, for example, heavy calcium carbonate, calcium carbonate, light calcium carbonate, barium sulfate, clay, kaolin, porcelain clay, china clay, talc, precipitated barium sulfate, barium carbonate, white carbon, diatomaceous earth. And hollow beads.

上記粉粒体の混合比率は、ベース塗材中の樹脂固形分１００重量部に対し、通常１０〜１０００重量部、好ましくは２０〜５００重量部、より好ましくは３０〜３００重量部程度である。
ベース塗材においては、とりわけ平均粒子径０．５μｍ以上５０μｍ以下（さらには１μｍ以上４５μｍ以下）の粉体を上記比率で含むものが好適である。
The mixing ratio of the granular material is usually about 10 to 1000 parts by weight, preferably about 20 to 500 parts by weight, and more preferably about 30 to 300 parts by weight with respect to 100 parts by weight of the resin solid content in the base coating material.
In particular, the base coating material preferably contains a powder having an average particle size of 0.5 μm or more and 50 μm or less (more preferably 1 μm or more and 45 μm or less) in the above ratio.
ベース塗材は、上記成分の他、通常塗材に混合可能な種々の成分を含むことができる。このような成分としては、例えば、希釈剤、造膜助剤、硬化剤、可塑剤、防腐剤、防黴剤、防藻剤、抗菌剤、増粘剤、消泡剤、レベリング剤、界面活性剤、顔料分散剤、沈降防止剤、たれ防止剤、湿潤剤、触媒、硬化促進剤、脱水剤、消泡剤、艶消剤、凍結防止剤、紫外線吸収剤、酸化防止剤、光安定剤等が挙げられる。 The base coating material can contain various components that can be mixed with the normal coating material in addition to the above components. Such components include, for example, diluents, film-forming aids, curing agents, plasticizers, preservatives, antifungal agents, antialgae agents, antibacterial agents, thickeners, antifoaming agents, leveling agents, and surface active agents. Agents, pigment dispersants, anti-settling agents, anti-sagging agents, wetting agents, catalysts, curing accelerators, dehydrating agents, antifoaming agents, matting agents, antifreezing agents, UV absorbers, antioxidants, light stabilizers, etc. Is mentioned.
骨材含有塗材の色調は、最終的な仕上り性等を勘案して適宜設定することができる。骨材含有塗材を着色するには、着色顔料等を用いて所望の色調に調整すればよい。この際、骨材含有塗材の色調を、上塗材に近似した色相（共色）に設定しておけば、下地面が露出した場合であっても違和感のない仕上りとなる。 The color tone of the aggregate-containing coating material can be appropriately set in consideration of the final finish and the like. In order to color the aggregate-containing coating material, it may be adjusted to a desired color tone using a coloring pigment or the like. At this time, if the color tone of the aggregate-containing coating material is set to a hue (co-color) similar to that of the top coating material, even if the base surface is exposed, the finish is not uncomfortable.
骨材含有塗材の塗装方法としては、特に限定されず、吹付け塗装、ローラー塗装、コテ塗り等の方法を採用することができる。骨材含有塗材の塗付け量は、通常０．２〜８ｋｇ／ｍ２（好ましくは０．５〜６ｋｇ／ｍ２）程度である。 The method for applying the aggregate-containing coating material is not particularly limited, and methods such as spray coating, roller coating, and trowel coating can be employed. The coating amount of the aggregate-containing coating material is usually about 0.2 to 8 kg / m 2 (preferably 0.5 to 6 kg / m 2 ).
本発明では、上記骨材含有塗材の塗付時ないし塗付後に、その塗面の一部の領域に対し、骨材を埋没させる処理（ａ）、骨材を露出させる処理（ｂ）、及び骨材を除去する処理（ｃ）から選ばれる１種以上の処理を施すことが望ましい。このような処理により、骨材による凹凸が形成された凹凸領域と、当該凹凸領域よりも凹凸が平坦化された平坦領域とが混在した下地面を形成することができる。なお、本発明における平坦化とは、下地面において、骨材による凸部の高さ及び／または密度が相対的に小さくなることを意味する。 In the present invention, at the time of application of the aggregate-containing coating material or after application, a process of burying the aggregate (a), a process of exposing the aggregate (b) to a partial region of the coated surface, It is desirable to perform one or more treatments selected from the treatment (c) for removing the aggregate. By such a process, it is possible to form a base surface in which an uneven region where unevenness is formed by aggregate and a flat region where unevenness is flattened than the uneven region are mixed. In addition, the planarization in this invention means that the height and / or density of the convex part by an aggregate become relatively small in a base surface.
上記処理（ａ）は、骨材を埋没させる処理である。このような処理は、通常、骨材含有塗材の塗付時、ないし骨材含有塗材の塗面の乾燥前までに行えばよい。
処理（ａ）では、骨材含有塗材の塗面に露出した状態の骨材を、押圧することにより、骨材がベース塗材内に埋没した状態となる。押圧の際には、各種押圧具を使用すればよい。押圧具としては、骨材を埋没させることが可能なものであればよく、例えば、コテ、ヘラ、プラスチックローラー等が使用できる。その他、種々の板材やデザインローラー等も使用可能である。
The process (a) is a process of burying the aggregate. Such treatment may be usually performed at the time of applying the aggregate-containing coating material or before drying the coated surface of the aggregate-containing coating material.
In the process (a), the aggregate exposed in the coating surface of the aggregate-containing coating material is pressed, whereby the aggregate is buried in the base coating material. What is necessary is just to use various pressing tools in the case of a press. The pressing tool only needs to be able to bury the aggregate, and for example, a trowel, a spatula, a plastic roller, or the like can be used. In addition, various plate materials and design rollers can be used.
上記処理（ｂ）は、骨材を露出させる処理である。このような処理は、通常、骨材含有塗材の塗付時、ないし骨材含有塗材の塗面の乾燥前までに行えばよい。
処理（ｂ）では、ベース塗材内に埋没した状態の骨材を露出させるため、骨材周辺のベース塗材を除去すればよい。
ベース塗材を除去するには、例えば、ベース塗材を掻き取る方法や、吸収する方法等を採用することができる。このうち、前者では、ブラシ等を用いて骨材周辺のベース塗材を除去すればよい。後者では、スポンジ、布等の吸液性材料を塗面に接触させる手段を用いることができる。
また、これらの方法を行う際には、ベース塗材を軟化または溶解させることで、作業の効率化を図ることもできる。ベース塗材を軟化または溶解させるには、ベース塗材の塗面に、水、溶剤等の媒体が接触するようにして処理を行えばよい。
The process (b) is a process for exposing the aggregate. Such treatment may be usually performed at the time of applying the aggregate-containing coating material or before drying the coated surface of the aggregate-containing coating material.
In the process (b), in order to expose the aggregate buried in the base coating material, the base coating material around the aggregate may be removed.
In order to remove the base coating material, for example, a method of scraping the base coating material or a method of absorbing the base coating material can be employed. Of these, in the former, the base coating material around the aggregate may be removed using a brush or the like. In the latter case, means for bringing a liquid-absorbing material such as sponge or cloth into contact with the coated surface can be used.
Moreover, when performing these methods, work efficiency can also be improved by softening or dissolving the base coating material. In order to soften or dissolve the base coating material, treatment may be performed so that a medium such as water or a solvent is in contact with the coated surface of the base coating material.
上記処理（ｃ）は、骨材を除去する処理である。このような処理は、骨材含有塗材の塗付時、ないし骨材含有塗材の塗面の乾燥前までに行えばよいが、場合により、骨材含有塗材の塗面の乾燥後に行うこともできる。
処理（ｃ）では、骨材含有塗材の塗面に露出した状態の骨材を除去し、その周辺のベース塗材が残存するように処理すればよい。また、処理（ｃ）では、骨材を除去した箇所に著しい凹み等が残存しないように、骨材除去の方法やタイミング等を選定すればよい。除去の際には、例えば、刷毛、研磨紙等を用いることができる。
The process (c) is a process for removing the aggregate. Such treatment may be performed at the time of application of the aggregate-containing coating material or before the drying of the coating surface of the aggregate-containing coating material. You can also.
In the process (c), the aggregate exposed in the coating surface of the aggregate-containing coating material may be removed and the surrounding base coating material may be left. In the process (c), the aggregate removal method, timing, etc. may be selected so that no significant dents or the like remain at the location where the aggregate has been removed. In the removal, for example, a brush, abrasive paper, or the like can be used.
本発明では、工程（１）において、平坦な基材に対し、少なくとも１種以上の上記骨材含有塗材を、基材の一部の領域に部分的に塗付することによって、凹凸領域と平坦領域とが混在した下地面を形成することもできる。この方法では、通常、骨材含有塗材による塗膜の一部ないし全部が凹凸領域となり、基材が平坦領域となる。また、この方法では、上記（ａ）〜（ｃ）の処理を行ってもよいが、省略することもできる。 In the present invention, in step (1), at least one kind of the above-mentioned aggregate-containing coating material is partially applied to a partial region of the base material with respect to the flat base material, A base surface mixed with a flat region can also be formed. In this method, usually, a part or all of the coating film formed by the aggregate-containing coating material becomes an uneven region, and the substrate becomes a flat region. In this method, the processes (a) to (c) may be performed, but may be omitted.
さらに、工程（１）では、骨材の平均粒子径及び／または含有比率が異なる２種以上の骨材含有塗材を用いることによって、凹凸領域と平坦領域とが混在した下地面を形成することもできる。この方法では、通常、平均粒子径が大きい骨材を含む塗材による塗膜の一部ないし全部が凹凸領域となり、相対的に平均粒子径が小さい骨材を含む塗材による塗膜の一部ないし全部が平坦領域となる。一方、骨材の含有比率については、その含有比率が高い塗材による塗膜の一部ないし全部が凹凸領域となり、相対的に含有比率が低い塗材による塗膜の一部ないし全部が平坦領域となる。この方法において、上記（ａ）〜（ｃ）の処理は行ってもよいが、省略することも可能である。 Furthermore, in the step (1), by using two or more kinds of aggregate-containing coating materials having different average particle diameters and / or content ratios of the aggregates, a base surface in which uneven regions and flat regions are mixed is formed. You can also. In this method, usually, a part or all of the coating film made of a coating material containing an aggregate having a large average particle diameter becomes an uneven region, and a part of the coating film made of a coating material containing an aggregate having a relatively small average particle diameter. Or all become flat areas. On the other hand, as for the content ratio of the aggregate, a part or all of the coating film formed by the coating material having a high content ratio becomes an uneven area, and a part or all of the coating film formed by the coating material having a relatively low content ratio is a flat area. It becomes. In this method, the processes (a) to (c) may be performed, but may be omitted.
以上の工程（１）により得られる凹凸領域、平坦領域の形状、面積等は、所望の仕上面が得られるように適宜設定すればよい。本発明では、例えば、一方の領域の中に他方の領域が島状に散在する状態、一方の領域の中に他方の領域が線状に存在する状態、それぞれの領域が交互に並んだ状態等を形成することが可能である。 What is necessary is just to set suitably the uneven | corrugated area | region obtained by the above process (1), the shape, area, etc. of a flat area | region so that a desired finishing surface may be obtained. In the present invention, for example, a state in which the other region is scattered in an island shape in one region, a state in which the other region is linearly present in one region, a state in which the respective regions are alternately arranged, etc. Can be formed.
本発明では、上記下地面に対し、着色塗料の粒状物（「着色粒子」ともいう）が分散媒中に分散した上塗材を塗付する。
上述の通り、本発明における下地面では、骨材による凹凸が形成された凹凸領域と、当該凹凸領域よりも凹凸が平坦化された平坦領域とが混在した状態となっている。このような下地面に対して、上記上塗材を塗付することにより、平坦領域では、上塗材に含まれる着色粒子が、塗付時の外力により変形して潰れやすい（広がりやすい）ため、比較的大きな色粒によって模様が形成される。他方、凹凸領域では、塗付時に外力が加わっても、骨材が障壁となって着色粒子が広がりにくいため、比較的小さな色粒によって模様が形成される。すなわち、同一面内に、比較的大きな色粒による模様領域と、比較的小さな色粒による模様領域とが混在することとなる。
本発明では、このように凹凸領域と平坦領域で上塗材の仕上状態に視覚的変化が生じる。具体的に、平坦領域では各色粒自体の色調が認識されやすくなり、凹凸領域では各色粒が混ざり合ったような色調で認識されやすくなる。このような視覚的変化により、本発明では従来技術では得られなかった美観仕上げが可能となる。
In the present invention, the base material is coated with a top coating material in which particulates of colored paint (also referred to as “colored particles”) are dispersed in a dispersion medium.
As described above, the ground surface in the present invention is in a state in which a concavo-convex region in which the concavo-convex portion is formed by the aggregate and a flat region in which the concavo-convex region is flattened are mixed. By applying the above-mentioned overcoating material to such a base surface, in a flat region, the colored particles contained in the overcoating material are easily deformed and crushed (extended) by the external force at the time of application. Patterns are formed by large color grains. On the other hand, in the uneven area, even if an external force is applied at the time of application, the aggregate becomes a barrier and the colored particles are difficult to spread, so that a pattern is formed with relatively small color particles. That is, a pattern region with relatively large color grains and a pattern region with relatively small color grains are mixed in the same plane.
In the present invention, a visual change occurs in the finished state of the top coating material in the uneven region and the flat region in this way. Specifically, the color tone of each color grain itself is easily recognized in a flat region, and the color tone of each color particle is easily recognized in a concavo-convex region. Such a visual change enables an aesthetic finish that is not possible with the prior art in the present invention.
本発明で用いる上塗材は、分散媒中に、着色塗料の粒状物が分散したものである。このような上塗材は、塗付時に変形可能な着色粒子を含むものであればよく、一般に多彩模様塗料として知られている材料を使用することができる。多彩模様塗料は、ＪＩＳ Ｋ５６６７（２００２）「多彩模様塗料」に規定されており、塗料を構成する分散媒と着色粒子の組み合わせによって、水中油型（Ｏ／Ｗ型）、油中水型（Ｗ／Ｏ型）、油中油型（Ｏ／Ｏ型）及び水中水型（Ｗ／Ｗ型）の４種類に分類される。本発明における上塗材としては、特に、水中油型（Ｏ／Ｗ型）または水中水型（Ｗ／Ｗ型）の多彩模様塗料が好適である。 The top coating material used in the present invention is a dispersion medium in which particles of colored paint are dispersed in a dispersion medium. Such an overcoating material is sufficient if it contains colored particles that can be deformed during application, and materials generally known as multicolored paints can be used. The multicolored paint is defined in JIS K5667 (2002) “Multicolored paint”. Oil-in-water type (O / W type), water-in-oil type (W / O type), oil-in-oil type (O / O type), and water-in-water type (W / W type). As the coating material in the present invention, an oil-in-water type (O / W type) or a water-in-water type (W / W type) multicolored paint is particularly suitable.
上塗材に含まれる着色粒子は、塗付時に変形可能なものであれば、ある程度ゲル化した状態であってもよい。
着色粒子の色相は、最終的に形成される模様に応じて適宜設定すればよい。本発明において使用する上塗材としては、通常２色以上、好ましくは３〜８色程度の着色粒子が含まれるものが好適である。
着色粒子の粒径も、最終的に形成される模様に応じて適宜設定すればよいが、通常は０．０１〜５ｍｍ、好ましくは０．１〜２ｍｍ程度である。粒子径が異なる着色粒子を種々組み合せることによって、意匠性の幅を広げることもできる。
The colored particles contained in the top coating material may be in a gelled state to some extent as long as they can be deformed at the time of application.
What is necessary is just to set suitably the hue of a colored particle according to the pattern finally formed. As the coating material used in the present invention, those containing usually 2 or more colors, preferably about 3 to 8 colored particles are suitable.
The particle size of the colored particles may be appropriately set according to the pattern finally formed, but is usually 0.01 to 5 mm, preferably about 0.1 to 2 mm. By combining various colored particles having different particle diameters, the range of design properties can be expanded.
上塗材の塗装方法については、本発明の効果が奏される限り、種々の方法を採用することができるが、本発明では吹き付け塗装が好適である。
上塗材の塗付け量は、最終的な模様の種類によって異なるが、通常０．１〜１ｋｇ／ｍ２程度である。上塗材の乾燥は、通常、常温で行えばよい。
Various methods can be employed for the coating method of the top coating material as long as the effects of the present invention are achieved, but spray coating is preferred in the present invention.
The amount of the top coat applied varies depending on the final pattern type, but is usually about 0.1 to 1 kg / m 2 . The top coat material may be usually dried at room temperature.
本発明では、上塗材の塗膜が乾燥した後、必要に応じクリヤー塗料を塗付することもできる。特に耐候性が要求される構造物外部の部位に施工する際には、保護の目的でクリヤー塗料を塗付するのが好ましい。
また、本発明では、通常、下地面に対し直接上塗材を塗付するが、本発明の効果を阻害しない限り、必要に応じ中塗材等を塗付した後に上塗材を塗付することも可能である。
また、目地棒や目地型枠等の目地材の使用によって、格子状、幾何学模様状等の目地部を形成することもできる。この場合は、目地色となる色調で塗装を施した基材に、目地材を貼り付けた後、上記工程を行い、その後に目地材を除去すればよい。
In the present invention, after the coating film of the top coat material is dried, a clear paint can be applied as necessary. It is preferable to apply a clear paint for the purpose of protection, particularly when the construction is performed on a part outside the structure where weather resistance is required.
In the present invention, the top coat material is usually applied directly to the base surface. However, as long as the effect of the present invention is not impaired, it is possible to apply the top coat material after applying the intermediate coat material as necessary. It is.
In addition, joint portions such as a lattice shape and a geometric pattern shape can be formed by using joint materials such as joint rods and joint form frames. In this case, the joint material may be attached to a base material that has been coated with a color tone that becomes a joint color, and then the above-described process may be performed, and then the joint material may be removed.
