Abstract
The invention relates to a visible-light nano titanium dioxide photocatalysis sterilization purification solid powder coating. The coating is characterized by comprising the following raw materials in percentage by weight: 1 to 20 percent of nano titanium dioxide with visible-light activity, 20 to 70 percent of silicate, 3 to 5 percent of gypsum powder, 5 to 10 percent of titanium pigment, 0.1 to 5 percent of powder anti-caking agent, 1 to 10 percent of curing conditioner, 1 to 10 percent of inorganic pigment and 1 to 20 percent of filling material. The pure inorganic inner-outer wall solid powder coating has good natural light photo-catalytic activity, and can effectively adsorb and decompose toxic and harmful gases, purify the air, kill bacteria and prevent mildew. The solid powder coating is easy to store and transport, and is simple in use method.
Description
Technical field
The present invention relates to a kind of pure inorganic environment-friendly coating, particularly relate to a kind of have visible light catalysis activity, fungus and mildew resistance, can the solid powder paint of decontamination chamber's inner air and outer air.
Background technology
Current domestic indoor finishing paint major part is organic coating, this type of is several or tens kinds of organic composition compositions, in use, organic composition volatilization or weather aging are decomposed into small organic molecule, and as the obnoxious flavour such as benzene, formaldehyde, harm humans is healthy, and organic coating production process is complicated, serious waste of resources, again can to environment, and the mankind produce direct or indirect harm.Inorganic paint composition is mineral compound, derives from natural mine, rich reserves, and inorganic paint is stablized, and does not produce pollutent, environmental protection and energy saving.Particularly visible light nano optically catalytic TiO 2 inorganic paint, just has and purifies air, the effects such as kill bacteria, mould, virus under natural light, and is easy to store and transport, easy construction, environmental protection.
Summary of the invention
Object of the present invention is just in order to provide a kind of pure inoganic solids powder coating, and for indoor and outdoor environmental protection finishing, itself can not produce pollutent, and have purify air under visible light, the effect such as kill bacteria, environmental protection.Can directly replace putty powder and emulsion paint, and sand-cement slurry metope directly combines, firmly, non-scale, does not come off, not crackle.Can make various modeling wall surface, cost is low.
Object of the present invention realizes by following technique measures:
Visible light nano titanium oxide photocatalysis disinfectant purification solid powder paint of the present invention comprises the raw material of following weight ratio, wherein: the nano titanium oxide 1 ~ 20% with visible light activity, silicate 20 ~ 70%, terra alba 3 ~ 5%, titanium dioxide 5 ~ 10%, powder anticaking agent 0.1 ~ 5%, solidification amendment 1 ~ 10%, mineral dye 1 ~ 10%, filler 1 ~ 20%.
Silicate described in the present invention takes from any one or a few the mixture in water glass, potassium silicate, lithium silicate, Calucium Silicate powder, Magnesium Silicate q-agent or pure aluminium silicate; The described nano titanium oxide with visible light activity is Detitanium-ore-type structure, has stronger visible ray light district response; Described powder anticaking agent takes from any one or a few the mixture in magnesium oxide, talcum powder, superfine silicon dioxide or light calcium carbonate; Any one or a few the mixture in Wingdale, barite, quartz or calcium phosphate taken from by described filler; Described mineral dye is toning mineral dye; Described solidification amendment is any one or mixture of condensed phosphate or ammonium salt.
The granularity of powder body material described in the present invention is less than 300 orders.
Terra alba described in the present invention is anhydrous plaster powder; Described titanium dioxide is commercial powder coating tailored version titanium dioxide, and white powder is nontoxic, stable chemical nature, and surface is through the process of the coating such as silicon, aluminium.Whiteness, brightness, glossiness are good, and opacifying power, reducing power are strong, are easy to dispersion.
Preparation method of the present invention is as follows: each component raw material is dry mixed together, grinds, rush nitrogen packed.
Coating of the present invention, according to GB/T23763-2009 detection method, reaches 99.99% to the antibiotic rate of intestinal bacteria, streptococcus aureus, Klebsiella pneumonia, Pseudomonas aeruginosa.
Gained coating experiment group two hours Degradation Formaldehyde rates are all higher than 55%.
Beneficial effect of the present invention is as follows:
1, the present invention gets final product decontamination chamber's inner air and outer air under visible light, and sterilization and disinfection, prevents from going mouldy.
2, the present invention is raw materials used is inoganic solids powder, and coating is easy to store and transport, and construction process is harmless.
3, the present invention is raw materials used without organic composition, avoids organic composition volatilization or degradation and decomposition and slow releasing toxic and harmful.
4, stable performance, can directly replace putty powder and emulsion paint, and sand-cement slurry metope directly combines, and firmly, non-scale, does not come off, not crackle.Can make various modeling wall surface, cost is low.
