When the coating is sprayed or applied to the municipal basic affiliation facilities and naturally dried, the PM2.5 can be decreased to about 20%-40% in a very short period under the action of natural light or ultraviolet light.

Description

Reduce environmental protection coating material of air PM2.5 and preparation method thereof
Technical field
The present invention relates to a kind of environmental protection coating material that can reduce air PM2.5 and preparation method thereof.
Background technology
Since 2014, all parts of the country there occurs serious haze phenomenon, it is serious where visibility less than 10m.Beijing The haze sky in January reaches 24 days.The pollution of environment causes people greatly fear and concern, and more people begin to focus on PM2.5.PM2.5 constituents are more complicated, mainly by vehicle exhaust, waste incineration, secondary inorganic aerosol, industrial pollution and Fire coal etc. is constituted.For the harm of PM2.5, government takes and closes down with serious pollution industrial premises, cuts off the pollution in source, by force Change Motor Vehicle Pollution Prevention, improve the means such as environment access threshold, expect that air quality was reached by 2017 is obviously improved, The average annual concentration of PM2.5 reduces by 20% and arrives purpose.
In recent years, it has been found that nano titanium oxide can effectively decompose the polluter in environment as photocatalyst, Play a part of environment purification, become " new lover " of field of environment protection, be widely used in field of environment protection.But it is empty for reducing The research of gas PM2.5 is actually rare, and the method operation of research at present is more complicated, and economic benefit is little.It is existing containing photocatalysis The coating of agent is not directed to PM2.5 particular formulations, and the reduction effect to PM2.5 is limited.Additionally, existing environmental protection coating material product is also deposited Low in strength of coating, the defect such as poor with basic unit adhesive ability has to be solved.
The content of the invention
The present invention provides a kind of environmental protection coating material of reduction air PM2.5 and preparation method thereof, will solve existing environmental protection coating material Reduction effect to PM2.5 is limited, and photocatalyst material easily causes the technical problem of secondary pollution to environment；And solve strength of coating Low, poor with basic unit adhesive ability technical problem.
The technical solution adopted for the present invention to solve the technical problems is：
The environmental protection coating material of this reduction air PM2.5, its each raw material components are as follows by weight ratio：
70～80 parts of covering；
7～15 parts of photocatalyst material；
1～15 part of reinforcing agent；
10～20 parts of additives；
The raw material of the additives is as follows by weight ratio：
0.1～0.5 part of dispersant；
0.1～0.5 part of defoamer；
10～20 parts of water.
The covering is Propylene Glycol, silicone acrylic emulsion, silane emulsion, one or more in epoxy resin solution Mixture.
The photocatalyst material is powdered titanium dioxide, one or two the mixture in Nano titanium dioxide.
The powdered titanium dioxide or Nano titanium dioxide are anatase titanium dioxide.
The reinforcing agent is microfine diatomaceous, Machine-made Sand, one or more the mixture in rubber powder.
The raw material of the reinforcing agent is as follows by weight ratio：
0～5 part of microfine diatomaceous；
0～6 part of Machine-made Sand；
0～4 part of rubber powder.
The preparation method of the environmental protection coating material of this reduction air PM2.5, preparation process are as follows：
Covering is stirred 10min, mix homogeneously according to proportioning under 500rpm rotating speeds by step one at normal temperatures；
Step 2, additives and reinforcing agent is added in covering according to proportioning, is stirred；
Step 3, photocatalyst material is added in the mixed liquor that step 2 is worked good according to proportioning, in 2000rpm rotating speeds Lower stirring 20min, stirs.
Beneficial effects of the present invention are as follows：
1st, common coating is during degraded vehicle exhaust etc. other harmful substances, its constituent nano titanium oxide Can be distributed in the air, to environment.Compared with other coating on the market, the environmental protection coating material of the present invention is considerably increased The usage amount of covering so that nano titanium oxide fully can be wrapped up completely, not result in the secondary pollution of environment.
2nd, environmental protection coating material manufacturing process is simple, and economic worth is high.Compared with common coating, this environmental protection is applied and has used enhancing Agent, is mainly made up of Machine-made Sand, rubber powder etc..The level that Machine-made Sand and rubber powder effectively can strengthen between each component matches somebody with somebody effect, Increase environmental protection and the adhesive force of basic unit so that coating preferably and substrate adhesive, simultaneously because its granule is small, can increase pedestrian The comfort level of walking.
3rd, environmental protection coating material of the invention reduction air PM2.5 effects are obvious.
Present invention sprinkling is applied on municipal basis affiliated facility, after its natural air drying, in natural light or ultraviolet light In the presence of, you can when very short, interior reduction PM2.5 reaches 20%～40% or so, and simple to operate, with it is very high should With value.
