Definitions
- This invention relates to the photocatalyst coating body as exterior materials, such as a building, and the photocatalyst coating liquid for the formation.
- photocatalysts such as titanium oxide have been used in many applications such as building exterior materials.
- photocatalyst it is possible to decompose various harmful substances using light energy, or to make the surface of the substrate coated with photocatalyst hydrophilic and easily wash away dirt adhering to the surface with water. .
- a technique for obtaining a photocatalyst by forming a coating film containing silica sol as a binder component and photocatalytic titanium dioxide on a substrate is known (for example, JP-A-11-169727 (Patent Document 1)).
- the amount of silica sol added is 20 to 200 parts by weight with respect to titanium dioxide on the basis of SiO 2 .
- the present inventors now comprise a photocatalyst layer with a specific composition that contains photocatalyst particles and inorganic oxide particles in a specific ratio, and that does not contain hydrolyzable silicone or suppress the amount to a minimum. It was found that a photocatalyst-coated body excellent in various properties, particularly harmful gas decomposability and weather resistance, can be obtained while suppressing erosion of the substrate, particularly an organic substrate.
- the present invention provides a photocatalyst-coated body excellent in various properties, particularly harmful gas decomposability and weather resistance, and a photocatalyst coating used for the formation thereof, while preventing erosion to a substrate, particularly an organic substrate. Its purpose is to provide liquid.
- the photocatalyst coating body by this invention is a photocatalyst coating body provided with a base material and the photocatalyst layer provided on this base material, Comprising:
- the said photocatalyst layer is 100 mass% of this photocatalyst layer whole. In this case, it comprises photocatalyst particles of more than 1% by mass and less than 3% by mass, inorganic oxide particles of more than 92% by mass and less than 99% by mass, and a binder of 0% by mass or more and less than 5% by mass.
- the photocatalyst coating liquid according to the present invention is a photocatalyst coating liquid used for the production of the photocatalyst-coated body, and the amount of the dry substance in the photocatalyst coating liquid is 100% by mass and exceeds 1% by mass with the solvent. It comprises less than 3% by weight of photocatalyst particles, more than 92% by weight and less than 99% by weight of inorganic oxide particles, and 0% by weight or more and less than 5% by weight of a binder.
- the photocatalyst-coated body according to the present invention is excellent in various properties, particularly harmful gas decomposability and weather resistance, while effectively preventing the erosion of the base material, particularly the organic base material. Furthermore, according to the preferable aspect of this invention, the photocatalyst coating body excellent also in hydrophilic property and desired various film characteristics (transparency, film

本発明の一形態によれば、光触媒塗装体は、基材と、該基材上に設けられた光触媒層とを備えてなる光触媒塗装体であって、前記光触媒層が、該光触媒層全体を100質量%としたときに、1.0質量%を超え3.0質量%未満の光触媒粒子と、92.0質量%を超え99.0質量%未満の無機酸化物粒子と、0質量%以上5.0質量%未満のバインダーとを含んでなる。
本発明において、基材は、その上に光触媒層を形成可能な材料であれば無機材料、有機材料を問わず種々の材料であってよく、その形状も特に限定されない。
本発明において、光触媒層は、基材表面に光触媒粒子が存在すれば、完全な膜状に加え、例えば、部分的に膜状になっている状態も包含する。また、基材表面上に島状に離散して存在していても良い。本発明の好ましい態様によれば、この光触媒層はコーティング液を適用して得られるものである。
本発明の一形態によれば、光触媒コーティング液は、上述の本発明による光触媒塗装体の形成のために使用するものである。光触媒コーティング液の乾燥物質量を100質量%としたときに、その組成は、溶媒と、1.0質量%を超え3.0質量%未満の光触媒粒子と、92.0質量%を超え99.0質量%未満の無機酸化物粒子と、0質量%以上5.0質量%未満のバインダーを含んでなる。
本発明の光触媒塗装体は、本発明の光触媒コーティング液を基材上に塗布することにより製造することができる。塗装方法は、刷毛塗り、ローラー、スプレー、ロールコーター、フローコーター、ディップコート、流し塗り、スクリーン印刷等、一般に広く行われている方法を利用できる。コーティング液の基材への塗布後は、常温乾燥させればよく、あるいは必要に応じて加熱乾燥してもよい。しかし、焼結が進むまで加熱すると粒子間の空隙が減少し十分な光触媒活性を得ることができなくなるおそれがあるため、空隙形成に影響を与えないあるいは影響が少なくなる温度および時間を選択することが好ましい。例えば、乾燥温度は10℃以上500℃以下であり、基材の少なくとも一部に樹脂が含まれる場合、樹脂の耐熱温度等を考慮し、例えば好ましい乾燥温度は10℃以上200℃以下である。
基材として50mmX100mmの平板状の着色有機塗装体を用意した。この着色有機塗装体は、シーラー処理した窯業系サイディング基材上に、カーボンブラック粉末を添加したアクリル塗料(シリコン含有せず)を塗布し、十分に乾燥および硬化させたものである。
