Abstract

The invention relates to a photocatalyst paint, which comprises the components by weight percentage as follows: 0.5-2% of nano titanium dioxide, 0.05-0.2% of nano titanium phosphate, 0.1-0.2% of nano silicon dioxide, 0.5-1.5% of negative ion nanopowder, 5-20% of paint emulsion, 0.001-0.004% of defoamer, 0.001-0.004% of coupling agent, 0.001-0.004% of dispersant, 0.01-0.04% of thickener and the balance of water. The photocatalyst paint has reasonable formula and remarkable effect, is convenient to prepare, and can purify air rapidly, effectively and persistently so as to thoroughly eliminate peculiar smells indoors and harmful gases such as formaldehyde, benzene, ammonia and the like, solve the problem of pollution indoors and effectively keep the people indoors in good health.

Description

A kind of photo-catalytic coating

Technical field

The present invention relates to chemical field, especially a kind of photo-catalytic coating.

Background technology

It is the same with other organism CO2 to be converted into oxygen through photosynthesis like chlorophyll; After the ultraviolet ray of special titanium oxide (Ti O2) in absorbing the sun and luminescent lamp; Can oxygen around it and water molecules be converted to and have active active oxygen layer, this active oxygen again can be with organic substance (formaldehyde, acetaldehyde on every side; Ammonia, bacterium etc.) be decomposed into water and CO2.This effect just is called the photocatalyst effect.Nano photo-catalytic environmental protection coating material product by the development and application in succession of domestic and international coating material production company, shows the using value of this photo-catalytic coating in various fields.Coating can produce unique photocatalysis under the effect of light after adding the nano titanium oxide photocatalyst, can not only airborne toxic and harmful be decomposed and eliminate, and bacterium, mould, virus are had very strong killing action.For example obnoxious flavoures such as the nano antibacterial coating formaldehyde that can interior decoration be produced, toluene, YLENE, ammonia are powerful decomposes and eliminates, and makes room air more pure and fresh, the harm of having avoided toxic and harmful that human body is caused.Because people spent indoor above 80% time, IAQ is the quality of life of affect people's greatly, health level and working efficiency.

The air pollution problems inherent that use nanometer light matchmaker coating can effectively solve interior decoration to be caused, and have secular mildew-resistant algae preventive effect.Simultaneously, the nano photo-catalytic antibacterial environmental protection coating material has good self-cleaning anti-pollution function, can keep long-term clean attractive in appearance; Have remarkable high-weatherability, it is good to protect light guarantor chromatic effect; Excellent water-fast, acidproof, alkali resistance, for a long time protect incrust; Sticking power is good, shows powerful abrasion resistance; Hardness of paint film height and flexible, hydrophobicity is splendid, cleans dirt easily.But the performance of existing photo-catalytic coating still is further improved.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can overcome the prior art deficiency, can purify air fast, efficient, persistent, thoroughly remove obnoxious flavoures such as foreign flavor indoors and formaldehyde, benzene, ammonia, suppress or the photo-catalytic coating of killing microorganisms.

The technical scheme that the present invention adopted is: a kind of photo-catalytic coating, and its moity weight percent is: nano titanium oxide 0.5-2%; Nanometer titanium phosphate 0.05-0.2%; Nano silicon 0.1-0.2%; Nano-negative ion powder 0.5-1.5%; Coating emulsion 5-20%; Skimmer 0.001-0.004%; Coupling agent 0.001-0.004%; Dispersion agent 0.001-0.004%; Thickening material 0.01-0.04%; Surplus is a water.

The present invention fills a prescription rationally, and easy to make, effect is obvious, can purify air fast, efficient, persistent, thoroughly removes obnoxious flavoures such as foreign flavor indoors and formaldehyde, benzene, ammonia, solves indoor pollution problem, and effective protection is healthy indoor people's.
