Description

A kind of composite photo catalyst coating
Technical field
The present invention relates to a kind of coating, be specifically related to a kind of composite photo catalyst coating.
Background technology
Studies have shown that many home decoration materials can slowly discharge such as small molecules objectionable impuritiess such as aldehydes, phenols, alcohols, easily HUMAN HEALTH are caused damage.In addition, along with the industrialization of human society and increasingly sharpening of urbanization, urban air pollution is also more and more serious.Make the atmospheric pollution of people's living environment serious day by day as obnoxious flavoures such as a large amount of sulfurous gas of dischargings such as industrial coal, vehicle exhaust, carbon monoxide, lower valency nitride.In addition, confirm that indoor microbial contamination is the one of the main reasons that causes various poisonings, infection, anaphylactic disease and communicate illness through investigation.This shows that researching and developing the material for air purification that a class is comprehensive, effect is rapid, easy to operate has become the task of top priority.
In recent years, a large amount of novel environmental type coating such as photo-catalytic coating etc. constantly occur and use.But the active adsorptive power of this class coating, the ageing and pleiotropy of work still are further improved.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of composite photo catalyst coating, can be initiatively, fast, lastingly, purify air in all directions, effectively suppress harmful microorganism.
The technical solution used in the present invention is as follows:
A kind of composite photo catalyst coating contains matrix material 30 ~ 45 weight parts, nano titanium oxide 15 ~ 30 weight parts, diatom ooze 5 ~ 20 weight parts, bamboo charcoal extracting solution 5 ~ 15 weight parts, film coalescence aid 4 ~ 8 weight parts, dispersion agent 0.2 ~ 0.5 weight part, water 20 ~ 30 weight parts.
Preferably, described matrix material is made up of AVE emulsion 10 ~ 20 weight parts, benzene emulsion 10 ~ 20 weight parts, organosilicon crylic acid latex 5 ~ 15 weight parts.
Preferably, described diatom ooze is the nanometer diatom ooze.
Preferably, described film coalescence aid is any one or more than one the combination in LG-DOW T40, T35, the T28 film coalescence aid.
Preferably, described dispersion agent is a Sodium hexametaphosphate 99.
The present invention has following beneficial effect:

(2) in addition, the bamboo charcoal extracting solution in the coating is rich in antibacterial elite, can effectively suppress various pathogens (as streptococcus aureus, Candida albicans, Pseudomonas aeruginosa, mould, intestinal bacteria, fungi etc.) rapidly, natural environmental-protective, and safety has no side effect;
(3) nano aperture of nanometer diatom ooze be common gac 5000-6000 doubly, adsorptive power is extremely strong, behind nano modification, by with airborne moisture interaction, a large amount of negative ions that discharge in suction discharges water process can in efficient absorbed air in the objectionable impurities, be removed objectionable impurities;
(4) nano titanium oxide, nanometer diatom ooze and bamboo charcoal extracting solution is used, make prepared coating can be comprehensive active catch and be free in airborne organic pollutant, inorganic pollutant and microorganism, thereby make composite photo catalyst coating of the present invention can be more initiatively, fast, efficiently, lastingly, purify air, thoroughly eliminate peculiar smell in all directions and suppress harmful pathogenic microorganisms;
(5) the present invention also contains matrix material such as AVE emulsion, benzene emulsion, organosilicon crylic acid latex, can guarantee the good sticking power of coating to body surface, can use forms of construction work such as brushing, spraying, easy and simple to handle, can be widely used in building, traffic appliance, bin outer surface.
