Description

A kind of stain resistant water-borne coatings

Technical field

The present invention relates generally to a kind of coating, relates in particular to a kind of stain resistant water-borne coatings.

Background technology

Coating is a kind of product that defencive function has again beautifying articles that has, and visible everywhere in the middle of people live, it is widely used in all respects such as building, steel product, woodenware, has become the indispensable product of society.

In the middle of a large amount of coating using and paint; different due to the quality of product and cost performance; also expose many problems; for example a lot of products use just there is not for a long time efflorescence, come off, the phenomenon of variable color (fading); its due defencive function is reduced greatly, lost the decoration function to object and article.Effect attractive in appearance and work-ing life are not long, have wasted greatly resource.

Its reason is exactly that people just think that coating, paint just can play the protection of object and increase gorgeous color for a long time, has ignored the Nature they are destroyed, and does not also understand coating and also needs protection with paint.

To the destruction of coating and paint, be mainly the cold and hot variation that derives from weather, the impact of dust storm, the infringement to it of environmental pollution and sunlight.If for the reason that causes coating with paint infringement, to its protection, just can make extend its work-ing life.

The annual production of domestic 2010 at present statistics building coatings is 5,000,000 tons of left and right, and the output of common paint, at-ten thousand tons, if can extend coating and the work-ing life of painting 10%, just means can reduce every year and produces 500,000 tons of building coatings, paint-ton.By 30,000 yuan/ton of calculating of middle-grade building coating, 1 year will reduce the use of 15,000,000,000 yuan of coating.This is a huge amount of money, if can reduce input, economize on resources, makes great efforts exactly to facilitate the concrete manifestation of conservation-minded society.Just can economize on resources with the energy, cut the waste and pollute, increase the economic benefit of user's use and the effect of social benefit.

Our company utilizes a kind of of high-tech approach research and production to have being applied to the existing coating such as building, steel-product, timber and plastics, painting the ultraviolet isolating paint that has defencive function.
