Description

本発明は、プライマー組成物に関するものである。   The present invention relates to a primer composition.

建築物の内装や外装には様々な素材が使用されている。これらの補修や塗り替えに、補修材や塗材に接着適性を持たせると本来の必要物性が得られないため、下地の素材と補修材、塗材にプライマーを介して密着性を確保する。できるだけ多くの被塗物に対応できるプライマーが望まれる。従来、被塗物の表面改質や密着適性がある樹脂を溶解させるため、溶剤を使用することが多かった。このため、臭気や環境汚染物質の放散があり、屋内施工環境の悪化があった。   Various materials are used for the interior and exterior of the building. In these repairs and repaints, if the repair material or coating material is given adhesion suitability, the original necessary physical properties cannot be obtained. Therefore, adhesion to the base material, the repair material, and the coating material is ensured through a primer. A primer that can handle as many objects as possible is desired. Conventionally, a solvent is often used to dissolve a resin having surface modification and adhesion suitability of an object to be coated. For this reason, there was an emission of odors and environmental pollutants, and the indoor construction environment was deteriorated.

プライマーの被着体も難接着オレフィン等のシーリング材対象が多く、建築物の床材に使用される塗床のエポキシ樹脂、ウレタン樹脂等の熱硬化性樹脂塗床や外壁等に使用されるタイル即ち、磁器質、せっ器質、さらにこれらに機能性を付与する目的として釉が表面に塗布されている物を被着体とするものはなかった。   Primer adherends are also often used for sealing materials such as hard-to-adhere olefins, and tiles used for thermosetting resin coatings such as epoxy resins and urethane resins used for building floors, and outer walls. In addition, there was no object to be adhered to the surface of porcelain, porcelain, or the like, with the surface coated with wrinkles for the purpose of imparting functionality thereto.

A primer composition characterized by blending a ring agent, which is a single liquid, water-based, excellent in adhesion to the undercoat, and has good adhesion to the top coat film.

請求項2の発明は、前記下地が、エポキシ樹脂塗材、ウレタン樹脂塗材、ウレタンセメント樹脂塗材、アクリルウレタン樹脂塗材、アクリル樹脂塗材、無機硬質基材のいずれかであることを特徴とする請求項1に記載のプライマー組成物で、塗り床材の塗り替え、内外壁の塗り替えなど、建築構造物の保護塗装ができる。   The invention according to claim 2 is characterized in that the base is any one of an epoxy resin coating material, a urethane resin coating material, a urethane cement resin coating material, an acrylic urethane resin coating material, an acrylic resin coating material, and an inorganic hard substrate.

図1は下地、プライマー、上塗り材の構成を示した説明図である。FIG. 1 is an explanatory diagram showing the structure of the base, primer, and topcoat material.

本願発明はウレタン樹脂自己乳化分散体をシードとするアクリル樹脂系エマルジョンにグリシジル基を有するシランカップリング剤を配合されたプライマー組成物が難接着である熱硬化性樹脂や無機質硬質材料に接着性が良く、このプライマー層が上塗り塗材となる硬化応力が発生する熱硬化性樹脂塗材を塗布しても密着性を維持できることである。   In the present invention, a primer composition in which a silane coupling agent having a glycidyl group is blended with an acrylic resin emulsion using a urethane resin self-emulsified dispersion as a seed is difficult to adhere to thermosetting resins and inorganic hard materials. It is good that adhesion can be maintained even when a thermosetting resin coating material that generates a curing stress is applied to the primer layer as a top coating material.

作用効果は明確ではないが、ウレタン樹脂自己乳化分散体をシードとするアクリル樹脂系エマルジョンの製造方法で、界面活性剤を使わないエマルジョンであり、シードとなる樹脂、官能基が水媒体側にあり、この対イオンを形成するものとグリシジル基を有するカップリング剤が複合的に作用し、これが、下地基材への密着性とプライマー層が形成後、被着体として上塗りの塗材応力にも耐えているものと考えられる。   Although the effect is not clear, it is an emulsion that does not use a surfactant in the production method of acrylic resin emulsion using a urethane resin self-emulsified dispersion as a seed, and the resin and functional group used as a seed are on the aqueous medium side. The compound that forms this counter ion and the coupling agent having a glycidyl group act in a complex manner, and this also affects the coating material stress of the top coat as an adherend after the adhesion to the base substrate and the primer layer are formed. It is considered enduring.

ウレタン樹脂自己乳化分散体をシードとするアクリル樹脂系エマルジョンは特開平5−132535号(米国特許5173526号)に基づくもので、概略を以下に記す。(a)カルボキシル基含有の、水分散性のイソシアネートを末端基とするポリウレタンプレポリマーを形成させ、(b)プレポリマーに、ポリエチレン系不飽和モノマーを含有するビニルモノマー組成物を加えてプレポリマー/モノマー混合物を形成させ、(c)プレポリマーを水分散性にするのに充分な量の第三アミンをプレポリマー/モノマー混合物に加え、(d)プレポリマー/モノマー混合物を水に分散させ、(e)水性分散液に油溶性の遊離基ラジカル開始剤と連鎖−伸長剤を加え、そして、(f)水性分散液を加熱してビニルモノマーを重合させ、そしてプレポリマーの連鎖伸長させる方法で、(a)はイソシアネートを末端基とするポリウレタンプレポリマーを形成させ、そしてそれを酸基−含有ジオールと反させるてもより、また(b)のビニルモノマー組成物はC1〜C6アルキル(メト)アクリレートである少なくとも1個のモノマー、スチレンまたはその混合物およびC2〜C6ジオールのジアクリレートであるポリエチレン系不飽和モノマーを含有するビニルモノマー組成物である。   An acrylic resin emulsion using a urethane resin self-emulsified dispersion as a seed is based on JP-A-5-132535 (US Pat. No. 5,173,526), and the outline is described below. (A) forming a polyurethane prepolymer containing a carboxyl group-containing water-dispersible isocyanate as a terminal group, and (b) adding a vinyl monomer composition containing a polyethylene-based unsaturated monomer to the prepolymer, (C) an amount of tertiary amine sufficient to make the prepolymer water-dispersible is added to the prepolymer / monomer mixture, (d) the prepolymer / monomer mixture is dispersed in water, e) adding an oil-soluble free radical radical initiator and a chain-extender to the aqueous dispersion, and (f) heating the aqueous dispersion to polymerize the vinyl monomer and chain-extending the prepolymer, (A) may form an isocyanate-terminated polyurethane prepolymer and reverse it with an acid group-containing diol. The vinyl monomer composition of (b) is a vinyl monomer containing at least one monomer which is a C1 to C6 alkyl (meth) acrylate, styrene or a mixture thereof and a polyethylene unsaturated monomer which is a diacrylate of a C2 to C6 diol. It is a composition.

前記方法で得られたウレタン樹脂自己乳化分散体をシードとするアクリル樹脂系エマルジョンは前記ビニルモノマー組成物の選択と組成率で硬軟選択ができ、固形分が高く、成膜後は耐水性がよい。これらの市販品にハイブリデュールHY570(エアプロダクツ社、商品名、伸び率200%)、ハイブリデュールHY580(同前、伸び率120%)、ダイトサイザーPU−060(大都産業(株))等がある。   The acrylic resin emulsion using the urethane resin self-emulsified dispersion obtained by the above method as a seed can be selected from the above-mentioned vinyl monomer composition and the composition ratio, can be hard and soft, has a high solid content, and has good water resistance after film formation. . These commercially available products include Hybridur HY570 (Air Products, trade name, growth rate 200%), Hybridur HY580 (same as above, growth rate 120%), Daito Sizer PU-060 (Daito Sangyo Co., Ltd.), etc. .

本発明で必須要素のグリシジル基を有するシランカップリング剤はアルコキシシランに1官能以上のグリシジル基を有するもので、他の官能基では組成物の安定性が得られないか、密着性で効果が得られない。ウレタン樹脂自己乳化分散体をシードとするアクリル樹脂系エマルジョンの固形分に対して、0.5〜3.0重量%が好ましい。この範囲で、組成物の安定性、効果が成り立つ。   The silane coupling agent having a glycidyl group, which is an essential element in the present invention, has one or more functional glycidyl groups in alkoxysilane, and the stability of the composition cannot be obtained with other functional groups, or the adhesion is effective. I can't get it. 0.5 to 3.0% by weight is preferable based on the solid content of the acrylic resin emulsion using the urethane resin self-emulsified dispersion as a seed. Within this range, the stability and effect of the composition are established.
