Abstract
Air purifying paint consists of organic silicon resin or solvent-gel adhesive 20-35 wt%, titania 50-60 wt%, and solvent 10-30 wt%. When the paint is applied to building, overpass and road side, its titania can absorb nitrogen oxide by the catalysis of sunlight and this can solve problem of nitrogen oxide pollution effectively.
Description
The present invention relates to the technical field of fine chemical product, specifically a kind ofly purify atmospheric coating.
Increasing along with vehicle, from the particulate matter of pollution especially severe, the especially NOx of vehicle exhaust, it is a kind of fatal carcinogenic substance, and is very big to people's health harm, at present the coating that also can effectively not handle the pollution of Nox of China.
The object of the present invention is to provide a kind of atmospheric coating that purifies, it can absorb the oxynitride in the atmosphere.
Technical scheme of the present invention is achieved in that a kind of atmospheric coating that purifies, it is characterized in that: it is by silicone resin or solvent-gel adhesive, titanium dioxide and solvent composition, the weight percent of described coating is silicone resin or solvent-gel adhesive 20-35%, titanium dioxide 50-60%, solvent 10-30%.
A kind ofly purify atmospheric coating, it is characterized in that: it is by silicone resin or solvent-gel adhesive, titanium dioxide and solvent composition, the weight percent of described coating is silicone resin or solvent-gel adhesive 20-35%, titanium dioxide 50-60%, solvent 10-20%, gac 3-5%.
Titanium dioxide among the present invention (TIO2) is a kind of metal oxide, its energy gap very big (being 3ev more), it is a kind of n N-type semiconductorN material, when titanium dioxide is subjected to ultraviolet radiation, can decomposite the electronegative electronics (e-) that moves freely and the hole (n+) of positively charged voluntarily, form hole-electron pair, the oxygen trapped electron that absorption is dissolved in titanium dioxide surface forms O2, OH and H2O that the hole then will be adsorbed on titanium dioxide surface are oxidized to HO, the atomic oxygen and the hydroxyl free radical that generate have very strong chemically reactive, can generate NO2 with the Nox reaction in the atmosphere, NO2 generates the buildings that HNO3 is coated in this product in the city with the H2O reaction on surface, viaduct, the both sides of road, utilize the catalysis of sunlight, but titanium dioxide absorbing NOx wherein, through test, the employing thickness is that this coating of 15um is put into flow-through reactor, with UV-lamp irradiation 24 hours, feeding concentration in reactor is the NO of 10ppm, flow is 1.5v/mim, the average decreasing ratio of NO can solve the pollution problem of oxynitride effectively more than 80%.
Below the invention will be further described and provide embodiment.
The present invention is a kind of atmospheric coating that purifies, it is characterized in that: it is by silicone resin or solvent-gel adhesive, titanium dioxide and solvent composition, the weight percent of described coating is silicone resin or solvent-gel adhesive 20-35%, titanium dioxide 50-60%, solvent 10-30%; Silicone resin or solvent-gel adhesive are film forming matter,-as silicone resin all can, described titanium dioxide is the ultrafine powder of 10-30 nanometer, as catalyzer, solvent among the present invention is ethanol, propyl alcohol, butanols, amylalcohol, ethyl acetate, butylacetate, acetone, cyclohexanone, toluene, dimethylbenzene, also can increase the auxiliary agent of 3-5% in the specific implementation, this auxiliary agent adopts gac or pigment, makes this coating have the versicolor coating of ventilation property, water tolerance and weathering resistance.
