Description
Technical field
The invention belongs to architectural decoration field of material technology, more particularly to comprehensive exterior wall paint special of a kind of high durable and preparation method thereof.
Background technology
Exterior wall paint is mainly used in building, is a kind of coating of brushing outside vertical surface of building.It possesses two kinds of functions：One is to protect building from external environment influence or influenceed to minimize; exterior wall paint can form continuous film after being applied on building on its surface; this film has the effect that corrosion-resistant, anti-pollution, UV resistant irradiation, resistance to bacterium corrode; protect reinforcing bar not perishable; protection concrete is difficult carbonization, chlorination, to extend the life-span of building；Two is decoration building, and exterior wall paint can form the film with different colours, various luster and different texture after being painted on building surface, so as to play a part of to beautify the environment.So, it is above-mentioned in most important several indexs be exactly that ultraviolet radiation resisting, corrosion-resistant, anti-pollution, resistance to bacterium corrode, it is desirable to reach irradiation nondiscolouring, not aging for a long time；Exterior coating has also required water repelling property, it is desirable to have self-cleaning property, and paint film wants hard and smooth, dirty once rushing.
But; the exterior wall paint for generally using at present is only to play a part of to decorate and protect wall from external environment influence; it does not possess heat-insulated and insulation function; and the weather resistance and water resistance of exterior coating also need to remain to be further improved, therefore current exterior wall paint there are certain limitation in use；Existing exterior wall paint, is usually formulated by water, pigment, coalescents, dispersant, defoamer, thickener, wetting agent, filler, antifreezing agent etc., and its pollution resistance, rub resistance are poor；And in summer, because strong ultraviolet irradiates, paint film is very easy to aging, generation loss of gloss, colour fading, discoloration, cracking, powder phenomenon-tion, decorative effect and use value are had a strong impact on.
The content of the invention
The present invention makes up the deficiency of existing exterior wall paint, there is provided a kind of comprehensive exterior wall paint special of high durable and preparation method thereof aiming above mentioned problem；The present invention has a high-weatherability, and good pollution resistance, rub resistance, anti-mealiness, anti-aging, water resistance etc. advantage, long service life.
