Abstract
The invention discloses a kind of composite photo catalysts and preparation method thereof, it is made of following parts by weight: 10-20 parts of nano-titanium dioxide, 4-10 parts of nano zine oxide, 6-12 parts of nano silica, 8-10 parts of active carbon nanoparticles, 3-8 parts of zinc sulphide, 5-9 parts of tungsten oxide, 4-8 parts of cadmium sulfide, 3-5 parts of platinum simple substance, 4-12 parts of sodium benzoate, 20-80 parts of dehydrated alcohol, 1-2 parts of auxiliary agent, 2-3 parts of surfactant, 10-15 parts of distilled water, the present invention is directed to the uncertain problem of solid activated carbon sorption chemical pollution effects, active carbon nanoparticles are added in the fabrication process, nano-titanium dioxide, nano zine oxide, the catalyst such as platinum, adsorb chemical pollutant by silane coupling agent, thoroughly remove pollutant, the change that the present invention can discharge finishing material after interior decoration Dissociated air state, surface adsorption state, internal combustion state that pollutant generates is learned effectively to be removed, permeated, be catalyzed, degraded, it can also be with biological pollutants such as elimination virus bacteriums.
Description
Technical field
The present invention relates to a kind of photocatalysts, more particularly, to a kind of composite photo catalyst and preparation method thereof.
Background technique
In the prior art, improve indoor environment to remove ski dome, solid activated carbon, photocatalyst, formaldehyde are molten
The products such as solution enzyme are current relatively widely used products.Chemical pollutant is mainly removed by way of absorption, due to not having
There are the chemical reactions such as generation oxidation, decomposition, so elimination effect is uncertain.
Photocatalyst is a kind of using Nano titanium dioxide as the total of the photosemiconductor material with photo-catalysis function of representative
Claim, it is coated on substrate surface, under the action of ultraviolet light and visible light, generates strong catalytic degradation function: can effectively drop
Solve toxic and harmful gas in air；It can effectively kill various bacteria, and the toxin that bacterium or fungi release can be decomposed and nothing
Evilization processing；It is also equipped with simultaneously except functions such as formaldehyde, deodorization, anti-pollution, purification air.The main component of photocatalyst is titanium dioxide
Titanium.The hydrone and oxygen molecule that can be generated in charge, with air under sunlight or ultraviolet light irradiation react, and produce
Raw negative oxygen ion and hydroxyl free radical, these substances have superpower oxidability, and ski dome substance can be made by oxygen
Change, the cell wall of virus and bacteria can also be made to be destroyed, achievees the purpose that remove indoor chemistry and biological pollution.This kind of medicament is logical
These nano particles are pasted onto body surface frequently with the mode of adhesive, form thin film.But the heat of this layer film
The coefficient of thermal expansion and contraction of swollen contraction coefficients and furniture and wall surface is impossible identical, because of furniture and paint for wall
Be it is multifarious, so common film technique can fall off with the extension film of time, film formation surface also can after friction
It is destroyed, medicament is caused to fail.
Currently, the clean-up effect of the substances such as existing composite photo catalyst PARA FORMALDEHYDE PRILLS(91,95), benzene, ammonia is not good enough, therefore provide newly
Composite photo catalyst and preparation method thereof.
Summary of the invention
The object of the present invention is to provide a kind of composite photo catalysts and preparation method thereof, to solve the problems of the prior art.
