Material.
Background technology
Chinese paint industry grows stronger day by day under the promotion of downstream industry, and as the building coating of one of branch,
Also significant progress has been obtained.Statistics shows that Chinese architecture coating in 2011 amounts to about 351.82 ten thousand tons of yield, increases on year-on-year basis
Long more than 30%.As can be seen here, although Chinese architecture paint industry experienced the influence of global financial crisis in 2008, former material
Material rise in price and Central Bank increase the interest the pressure brought, but its growth momentum does not subtract still, and also maintains higher growth rate.Apply
Material, which is covered with paint, lacquer, colour wash, etc., can very well bond with matrix material in body surface and form the material of complete and tough and tensile diaphragm, referred to as coating.Apply
Material and paint are identical concepts.Paint is people's custom title used for a long time, after introducing China, just utilizes and is gone in building always
Industry.The effect of coating may be summarized to be three aspects：Protective effect, decoration function, specific function effect.General group of coating
Into:Include film forming matter, color stuffing, solvent, auxiliary agent.
There is building coating decoration functions, defencive function and livability to improve function.Proportion shared by various functions is because making
It is not quite similar with purpose difference.Decoration functions are to improve the function of its appearance value by the beautification of building.Coating
In use, it can be corroded by environment, hollowing occur and come off and the problems such as wall leakage, existing water-repellent paint is for anti-
It is water-based also to be influenceed by environmental change and very unstable.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of high strength elastic waterproof architectural coating, Neng Gouji
