Description
本発明は意匠性に優れる塗装仕上げ方法に関し、詳しくは吹き付けガンを使用して仕上げる、意匠性に優れた塗装仕上げ方法に関するものである。 The present invention relates to a paint finishing method having excellent design properties, and more particularly to a paint finishing method having excellent design properties, which is finished using a spray gun.
従来、建築物の内外装の塗装仕上げ方法として、スプレー、ローラー、刷毛、鏝等の手段による意匠性に優れた塗装仕上げが採用されている。具体例としては、合成樹脂エマルジョンを主成分とするベース塗料を塗布してベース層を形成したのち、合成樹脂エマルジョン、軟質骨材、骨材等からなる上塗り塗料を鏝で引き延ばしながら塗布する際に該軟質骨材を鏝で潰しながら塗布仕上げする塗装仕上げ方法が開示されている（特許文献1参照）。さらに、合成樹脂エマルジョンを主成分とするベース塗料を塗布してベース層を形成したのち、合成樹脂エマルジョン、バーミキュライト、骨材等からなる上塗り塗料を鏝で塗布し、ついで上塗り層が乾燥しないうちに上塗り層の表面を水を含む刷毛で削り落とし、バーミキュライトの少なくとも一部を露出させる塗装仕上げ方法が開示されている（特許文献2参照）。
しかしながら、これら従来の塗装仕上げ方法は既に一般化された方法であるため、これまでにない意匠性を実現するためには更なる新規に塗装方法の開発が待たれていた。
反面、高度の熟練度を要する職人が年々減少して、熟練度を持たない作業者でも意匠性の高い塗装仕上げ方法が求められるような状況になっている。
However, since these conventional paint finishing methods are already generalized methods, development of a new coating method has been awaited in order to realize unprecedented design.
On the other hand, the number of craftsmen who require a high degree of skill is decreasing year by year, and even a worker who does not have the skill level is demanding a paint finishing method with a high design.
このような状況に鑑み、鋭意開発検討した結果、吹き付けガンによる塗装仕上げ方法により特有の風合いを持つ意匠性に優れた塗装仕上げ方法を確立するに至った。 In view of such a situation, as a result of earnest development and examination, it has come to establish a paint finishing method excellent in design with a unique texture by a paint finishing method using a spray gun.
第一工程として、合成樹脂エマルジョンを主成分とするベース樹脂を口径４〜６ｍｍの吹き付けガンで０．５〜１．０ｋｇ／ｍ２吹き付け、第二工程として、ベース樹脂と同一の合成樹脂エマルジョン、該樹脂固形分１０重量部に対して、長さ０．５〜１５ｍｍのワラスサ０．１〜０．５重量部、骨材を含み、粘度２５０〜５００Ｐａ・ｓ／３０℃の上塗り塗料を、口径４〜６ｍｍの吹き付けガンにより０．５〜２．０ｋｇ／ｍ２吹き付け、表面仕上げする方法からなるものである。尚、コンクリート、モルタル等の下地からのアルカリ、しみ等を遮断するためにウレタン樹脂、エポキシ樹脂等の樹脂を有機溶剤に溶解した溶剤系シーラー若しくはウレタン樹脂、エポキシ樹脂等をエマルジョン化した水系のシーラーを適宜、これら下地に塗布してシーラー層を設けることがなされても良い。
As a first step, a base resin mainly composed of a synthetic resin emulsion is sprayed at 0.5 to 1.0 kg / m 2 with a spray gun having a diameter of 4 to 6 mm. As a second step, the same synthetic resin emulsion as the base resin is used . with respect to the resin solid content 10 parts by weight, Warasusa 0.1 to 0.5 parts by weight of length 0.5 to 15 mm, includes the aggregate, the top coat paint of viscosity 250~500 Pa · s / 30 ℃, It consists of a method of spraying 0.5 to 2.0 kg / m 2 with a spray gun having a diameter of 4 to 6 mm and finishing the surface. In addition, a solvent-based sealer in which a resin such as urethane resin or epoxy resin is dissolved in an organic solvent or an aqueous sealer in which urethane resin or epoxy resin is emulsified in order to block alkali, stains, etc. from the ground such as concrete and mortar. The sealer layer may be provided by appropriately applying to the undercoat.
ベース層上に上塗り層を吹き付けて仕上げる際に、口径４〜６ｍｍの吹き付けガンにて、塗布量０．５〜２．０ｋｇ／ｍ ２ 程度吹付け、上塗り層を形成すると、ワラスサが露出した特有の風合いを持つ意匠性に優れた塗装仕上げに形成される。
When finish by blowing overcoat layer on the base layer at spray gun caliber 4 to 6 mm, coating weight 0.5~2.0kg / m 2 about spraying, to form a topcoat layer, specific to Warasusa is exposed It is formed into a paint finish with an excellent design with a texture of.
本発明における第一工程のベース層は合成樹脂エマルジョンを吹付けにより塗布することにより下地の不陸を調整し、上塗り層の付着性を確保するために形成させる。
ベース層のベース塗料には主成分の合成樹脂エマルジョンに骨材、充填材、顔料、増粘剤、分散剤、防カビ剤、防藻剤等を配合し、適度の流動性、塗布性を付与させることができる。
ベース塗料中の樹脂分は５〜２５％が適当し、５％以下では粘着性、塗布性等が低下して好ましくない。また２５％以上になると粘度が高くなる、添加剤、配合剤等の配合に制約が生じ好ましくない。
The base layer of the first step in the present invention is formed to apply the synthetic resin emulsion by spraying so as to adjust the unevenness of the base and ensure the adhesion of the overcoat layer.
The base layer base paint is blended with the main component synthetic resin emulsion with aggregates, fillers, pigments, thickeners, dispersants, fungicides, algae-proofing agents, etc. to give appropriate fluidity and coating properties. Can be made.
The resin content in the base paint is suitably 5 to 25%, and if it is 5% or less, the tackiness, applicability, etc. are unfavorable. On the other hand, if it is 25% or more, the viscosity becomes high, and there are restrictions on the blending of additives, blending agents, etc., which is not preferable.
第一工程のベース層の塗布量として０．５〜１．０ｋｇ／ｍ ２ 塗布する。
適正粘度としては２５０〜５００Ｐａ・ｓ／３０℃であり、２５０Ｐａ・ｓ／３０℃以下ではタレが生じて好ましくない。また５００Ｐａ・ｓ／３０℃以上では塗布作業が難しくなり好ましくない。このような適正粘度にするためには添加剤の種類、配合量等の選定により調整することができる。
As a coating amount of the base layer in the first step, 0.5 to 1.0 kg / m 2 is applied.
The proper viscosity is 250 to 500 Pa · s / 30 ° C., and if it is 250 Pa · s / 30 ° C. or less, sagging occurs, which is not preferable. Further, if it is 500 Pa · s / 30 ° C. or higher, the coating operation becomes difficult, which is not preferable. In order to obtain such an appropriate viscosity, it can be adjusted by selecting the kind of additive, the blending amount, and the like.
前記の合成樹脂エマルジョンとして例示すれば、アクリル酸エステル共重合系樹脂、酢酸ビニル樹脂、エチレン・酢酸ビニル系樹脂、酢酸ビニル・アクリル酸エステル系樹脂、エチレン・塩化ビニル系樹脂、シリコン変性アクリル系樹脂、ウレタン系樹脂等の合成樹脂エマルジョンが使用され、これらには架橋タイプ、粉末型のエマルジョン等であっても使用できる。 Examples of the synthetic resin emulsion include acrylate copolymer resins, vinyl acetate resins, ethylene / vinyl acetate resins, vinyl acetate / acrylate resins, ethylene / vinyl chloride resins, and silicon-modified acrylic resins. Synthetic resin emulsions such as urethane resins are used, and these can be used even in cross-linked type, powder type emulsions and the like.
骨材の種類は、一般に塗料に配合されるものであれば何ら問題無く使用できる。
例示すれば、珪砂、炭酸カルシウム、山砂、ガラス粉砕物、セラミック粉砕物等があり、これらは塗布方法により適正なサイズのものが選定使用されればよい。
また、粉体状の充填材、顔料も適宜使用される。
充填材、顔料の例として炭酸カルシュウム、カオリン、クレー、陶土、珪藻土、タルク、酸化チタン、ホワイトカーボン、酸化鉄、ベンガラ等があり、更に前記のように増粘剤、分散剤、防カビ剤、防藻剤等が適宜配合される。
Any type of aggregate can be used without any problem as long as it is generally blended with a paint.
For example, there are silica sand, calcium carbonate, mountain sand, glass pulverized material, ceramic pulverized material, etc., and these may be appropriately selected according to the coating method.
In addition, powdery fillers and pigments are also used as appropriate.
Examples of fillers and pigments include calcium carbonate, kaolin, clay, porcelain clay, diatomaceous earth, talc, titanium oxide, white carbon, iron oxide, bengara and the like. An algae or the like is appropriately blended.
ベース層を形成後、吹き付けガンにより０．５〜２．０ｋｇ／ｍ ２ の塗布量で上塗り層が形成される。
該上塗り層は主成分の合成樹脂エマルジョンとワラスサとを少なくとも配合したものからなり、その他の骨材、充填材、着色顔料、増粘剤、防カビ剤、防藻剤等が配合される。上塗り塗料の樹脂分は５〜２５％が適合していて、５％以下では粘着性、塗布性等が確保しにくく好ましくない。２５％以上ではコストが高くなり、また粘着性が高くなりすぎて作業性に難があり好ましくない。粘度に関しては２５０〜５００Ｐａ・ｓ／３０℃が適合し、２５０Ｐａ・ｓ／３０℃以下では塗料がタレるため好ましくない。５００Ｐａ・ｓ／３０℃以上では塗布作業性が著しく悪くなるため好ましくない。主成分の合成樹脂エマルジョン、その他充填剤等の配合剤は前記下塗り層に使用したと同様なものが使用できる。
After forming the base layer, an overcoat layer is formed with a spray gun at a coating amount of 0.5 to 2.0 kg / m 2 .
The overcoat layer comprises at least a main component synthetic resin emulsion and a wallacea, and other aggregates, fillers , color pigments, thickeners, fungicides, algaeproofing agents, and the like. The resin content of the top coating material is 5 to 25%, and if it is 5% or less, it is difficult to secure the adhesiveness, coating property, etc., which is not preferable. If it is 25% or more, the cost becomes high, and the tackiness becomes too high, resulting in difficulty in workability. With respect to the viscosity, 250 to 500 Pa · s / 30 ° C. is suitable, and if it is 250 Pa · s / 30 ° C. or less, the paint sagging is not preferable. When it is 500 Pa · s / 30 ° C. or higher, the coating workability is remarkably deteriorated. Compounding agents such as a synthetic resin emulsion as a main component and other fillers can be the same as those used for the undercoat layer.
上塗り層に配合するワラスサは長さが0.5〜1５ｍｍの形状を呈するものであり、0.5ｍｍ以下では吹付けた時に、ワラスサが露出しないため好ましくない。また、15ｍｍ以上では吹付けの時に、吹き付けガンの先端にワラスサが詰まるため好ましくない。 The wallacesa to be blended in the topcoat layer has a shape with a length of 0.5 to 15 mm, and when it is 0.5 mm or less, it is not preferable because the wallacesa is not exposed when sprayed. On the other hand, when the diameter is 15 mm or more, the tip of the spray gun becomes clogged with the tip of the spray gun, which is not preferable.
ワラスサの配合量は表面層に使用される塗料中の樹脂固形分１０重量部（以下部と称する）当たり０．１〜０．５部が適当し、０．１部以下では意匠性の発現が難しく目的を達成することができない。０．５部以上であってはワラスサ同士の重なり、凝集等のため仕上がりが悪くなるため好ましくない。
0.1 to 0.5 part is suitable for the blending amount of the wallacesa per 10 parts by weight (hereinafter referred to as “part”) of the resin solid content in the coating material used for the surface layer. Difficult to achieve purpose. An amount of 0.5 parts or more is not preferable because the finish is deteriorated due to the overlap and aggregation of the walls.
本発明による塗装仕上げ方法によれば、吹き付けガンによる塗装仕上げ方法により特有の風合いを持つ意匠性に優れた塗装仕上げ方法を確立するに至った。
このように吹き付けガンで様々な塗装仕上がりが特に高度の熟練度を要することなく実現できる。
According to the paint finishing method of the present invention, a paint finish method having a unique texture and excellent design properties has been established by a paint finishing method using a spray gun.
Thus, various painting finishes can be realized with a spray gun without requiring a high degree of skill.

After spraying a base paint with a resin solid content of 12.5% at 30 ° C. with a spray gun having a diameter of 4 to 6 mm to form a base layer having a thickness of about 0.3 mm, the size of the resin emulsion is the same as 20 parts of the base paint. Viscosity of 400 Pa · s / in which 0.1 parts of 0.5 to 15 mm wallacesa, calcium carbonate having a particle size of 0.1 to 0.2 microns as a filler, and titanium oxide as a coloring pigment were blended as shown in Table 1. About 1.2 kg / m 2 was sprayed on the top coat layer at 30 ° C. and 10.0% resin solid content with a spray gun. As a result, a unique spray-painted finish with an exposed wallacea was obtained.
実施例２

Example 2
On the same base layer as in Example 1, the viscosity of 420 Pa · s / 30 ° C. is the same except that in the formulation of the top coat of Example 1, the blending amount of Wallacesa is 0.5 part and 25 parts of water. A top coating was prepared and sprayed with about 1.2 kg / m 2 with a spray gun. As a result, a unique spray-painted finish with an exposed wallacea was obtained.
実施例３
実施例１と同一のベース層上に、実施例１の上塗り塗料の配合においてワラスサの配合量を０．５部、充填材の配合量を１５０部、水３５部とした以外は同一にして、粘度４２０Ｐａ・ｓ／３０℃の上塗り塗料を調製し、吹き付けガンにより１．２ｋｇ／ｍ ２ 程度吹き付けた。結果は、ワラスサが露出した独特の吹き付け塗装仕上がりが得られた。

Comparative Examples 1 and 2
Example 1 on the same base layer as in Example 1, except that the amount of Hurassa is 0 parts, 1.0 part, and the amount of water is 15 parts, 45 parts in the composition of the top coat of Example 1. The top coat of Comparative Examples 1 and 2 was prepared in the same manner as above, and sprayed by about 1.2 kg / m 2 with a spray gun. As a result, in Comparative Example 1, since the wallacesa was not blended, it was a flat finish without design. In Comparative Example 2, the amount of the wallacesa was excessive, so that the viscosity of the coating became too high, making the spraying operation difficult, and the tip of the spraying gun became clogged and the construction could not be performed.
比較例３
実施例１と同一のベース層上に、実施例１の上塗り塗料の配合においてワラスサの配合量を０．２部、水の配合量を２５部とし、ワラスサの長さが２０ｍｍ以上のものを使用した、以外は実施例１と同一にして比較例３の上塗り塗料を調製し、吹き付けガンにより１．２ｋｇ／ｍ ２ 程度吹き付けた。結果は、ワラスサが長いためガンの先端に詰まり施工ができなくなった。
Comparative Example 3
On the same base layer as in Example 1, in the formulation of the top coat of Example 1, 0.2% of the amount of Hurassa is blended, 25 parts of water is used, and the length of the Wallacesa is 20 mm or more. The top coat of Comparative Example 3 was prepared in the same manner as in Example 1 except that it was sprayed with about 1.2 kg / m 2 with a spray gun. As a result, because the wallacesa was long, it was clogged at the tip of the gun and could not be installed.
