The present invention is above-mentioned in order to overcome the shortcomings of, there is provided a kind of photocatalysis efficiency height, sterilization of high efficiency, nonhazardous, attached
The nanometer photocatalysis coating puted forth effort, it includes following components in percentage by weight：Zinc oxide 10-20 parts, titanium dioxide 20-40
Part, noble metal 1-3 parts, propylene Korean pine (2- p-nitrophenyls) thiadiazoles 10-20 parts, vanillic aldehyde 5-6 parts and other auxiliary agents 3-
4 parts；Wherein, the particle diameter of zinc oxide is 3-7nm, and the particle diameter of titanium dioxide is 8-12nm.
Nanometer photocatalysis coating of the present invention, the particle diameter of zinc oxide is 5nm, and the particle diameter of titanium dioxide is 10nm.
Nanometer photocatalysis coating of the present invention, the noble metal are gold, silver or platinum.
Nanometer photocatalysis coating of the present invention, other described auxiliary agents include weight ratio for 2:1:2:1:1:1 light stabilizer,
Thickener, dispersant, coalescent, defoamer and antifreezing agent.
Nanometer photocatalysis coating of the present invention, light stabilizer are salicylate, benzophenone, triazines, benzotriazole
One or more mixtures in UV absorbents and hindered amines free radical scavenger.
Nanometer photocatalysis coating of the present invention, defoamer are tributyl phosphate and/or dimethyl silicone polymer.
Nanometer photocatalysis coating of the present invention, antifreezing agent are 1,2-PD or ethylene glycol.
Nanometer photocatalysis coating of the present invention, dispersant are one kind in polyacrylate, enuatrol, polyvinylpyrrolidone
Or a variety of mixture.
Nanometer photocatalysis coating of the present invention, thickener are that the concentration that NatrosolTM250MR (Hercules) is sold is 3%
Hydroxyethyl cellulose solution.
Nanometer photocatalysis coating of the present invention, coalescent are the ester alcohol agglomerated solvent that Eastman Kodak are sold.
The beneficial effects of the invention are as follows：
1st, photocatalysis efficiency is high, and the present invention has strength point to finishing pollution thing formaldehyde, benzene, ammonia and other organic pollutions
Solve removal effect.Resolution ratio is up to more than 90%.Also purification efficiency is not reduced when concentration is low.PARA FORMALDEHYDE PRILLS(91,95), benzene, ammonia, sulfur dioxide,
The harmful organic substance that carbon monoxide, nitrogen oxides etc. influence human body health plays catharsis.
2nd, sterilization of high efficiency, sterilizing rate is up to more than 90%.Superpower oxidability can cause cell death, reduce virus
Activity, and catch, decompose planktonic bacteria in air.Effectively remove Escherichia coli, yellow staphylococcus, tinea alba bacterium, emblem bacterium,
The bacteriums such as pyogenic baeceria, green pus bacterium, suppress the propagation of such as enterovirus, influenza cause of disease.
3rd, nontoxic, photocatalyst photocatalysis can use as food additives.It is thin killing different from general disinfectant
While bacterium virus, also decomposable asymmetric choice net falls the toxin of its secretion, in the absence of secondary pollution problem.
4th, adhesive force is good, and anti-ultraviolet property is strong.
Embodiment
The present invention is further detailed explanation now.
A kind of nanometer photocatalysis coating, it includes following components in percentage by weight：Zinc oxide 10-20 parts, titanium dioxide
20-40 parts, noble metal 1-3 parts, propylene Korean pine (2- p-nitrophenyls) thiadiazoles 10-20 parts, vanillic aldehyde 5-6 parts and other
Auxiliary agent 3-4 parts.Wherein, the particle diameter of zinc oxide is 5nm, and the particle diameter of titanium dioxide is 10nm, and noble metal is gold, silver or platinum, described
Other auxiliary agents include weight ratio for 2:1:2:1:1:1 light stabilizer, thickener, dispersant, coalescent, defoamer and anti-
Freeze agent.
Above-mentioned light stabilizer is salicylate, benzophenone, triazines, the UV absorbents and hindered amine of benzotriazole
One or more mixtures in type free base agent for capturing.Defoamer is tributyl phosphate and/or dimethyl silicone polymer.
Antifreezing agent is 1,2-PD or ethylene glycol.Dispersant be polyacrylate, enuatrol, one kind in polyvinylpyrrolidone or
A variety of mixtures.Thickener is the hydroxyethyl cellulose that the concentration that NatrosolTM250MR (Hercules) is sold is 3%
Solution.Coalescent is the ester alcohol agglomerated solvent that Eastman Kodak are sold.
This coating has very strong redox ability in the presence of visible ray, and stable chemical performance can be by formaldehyde, first
The harmful organic substances such as the harmful organic substances such as benzene, dimethylbenzene, ammonia, radon, TVOC, pollutant, foul smell, bacterium, virus, microorganism are thorough
