特開2002−333093号公報JP 2002-333093 A 国際公開第2006/104290号International Publication No. 2006/104290

上記従来の熱遮蔽塗料の何れもが水性であるため、水あるいは低級アルコールのような水溶性溶媒がシリカ粒子表面に吸着し、シリカ粒子の光反射性を阻害すると云う問題点があった。   Since all of the above conventional heat shielding paints are water-based, there is a problem that water or a water-soluble solvent such as a lower alcohol is adsorbed on the surface of the silica particles and hinders the light reflectivity of the silica particles.

本発明は、上記従来の問題点を解決することを目的とし、合成樹脂の有機溶剤溶液に対して、レーザー回折散乱法による平均粒子径が1〜5μmの非晶質球状溶融シリカと、レーザー回折散乱法による平均粒子径が0.2〜0.4μmの酸化チタンとが、70:30〜30:70の質量比で混合されてなる無機充填材を、上記合成樹脂100質量部に対して300〜1000質量部の範囲で添加した熱遮蔽塗料を提供するものである。
所望なれば、上記熱遮蔽塗料には更に結晶質シリカを、上記合成樹脂100質量部に対して150質量部以下の範囲で添加してもよい。
上記合成樹脂は、アクリル系共重合体であることが望ましい。

The present invention provides a heat shielding paint added in the range of ˜1000 parts by mass.
If desired, crystalline silica may be further added to the heat shielding paint in an amount of 150 parts by mass or less with respect to 100 parts by mass of the synthetic resin.
The synthetic resin is preferably an acrylic copolymer.

〔作用〕
本発明の塗料は、溶剤として有機溶剤を使用しているので、シリカ粒子表面との親和性が低く、吸着されにくいので、シリカ粒子の光反射性が阻害されにくい。
本発明ではシリカ粒子のうち平均粒度1〜5μmの非晶質球状溶融シリカを使用しているが、上記シリカ粒子は表面の光反射性が良好である。
更に本発明では上記シリカ粒子に加えて酸化チタン粒子を添加して、上記シリカ粒子の光反射性を酸化チタン粒子の光触媒作用によって増強している。
更に上記非晶質球状溶融シリカに加えて結晶質シリカを添加して、非晶質球状溶融シリカの分散性を増強してもよい。
また本発明においては、合成樹脂として耐候性が良好なアクリル系共重合体を使用することが望ましい。
[Action]
Since the paint of the present invention uses an organic solvent as a solvent, it has a low affinity with the surface of the silica particles and is difficult to be adsorbed, so that the light reflectivity of the silica particles is not easily inhibited.
In the present invention, among the silica particles, amorphous spherical fused silica having an average particle size of 1 to 5 μm is used, but the silica particles have good surface light reflectivity.
Furthermore, in the present invention, titanium oxide particles are added in addition to the silica particles, and the light reflectivity of the silica particles is enhanced by the photocatalytic action of the titanium oxide particles.
Furthermore, in addition to the amorphous spherical fused silica, crystalline silica may be added to enhance the dispersibility of the amorphous spherical fused silica.
In the present invention, it is desirable to use an acrylic copolymer having good weather resistance as the synthetic resin.

〔効果〕
本発明では、熱遮蔽性が良好な熱遮蔽性塗料が得られ、上記熱遮蔽性塗料は、例えば建物の屋根材、自動車の内装材や外装材等に塗布されることによって、建物内や車内に熱が侵入しないように遮断して、冷房に要するエネルギーを大幅に削減する。
〔effect〕
In the present invention, a heat-shielding paint having good heat-shielding properties is obtained, and the heat-shielding paint is applied to, for example, building roof materials, automobile interior materials, exterior materials, etc. By blocking the heat from entering, the energy required for cooling is greatly reduced.
