Chemical blending method equally can be first to prepare PU emulsions and PA emulsions, then add crosslinking agent in any emulsion,
By mechanical agitation, the PU emulsions and PA emulsions of stabilization is set to be well mixed and crosslink, final curing film forming.Chemical blending method
PU and PA are connected together by the active force of chemical bond, so the combination property emulsion excellent compared with physical blending and painting can be obtained
Film.The crosslinking agent and crosslinking method found, improve its compatibility, it will improve the filming performance of blending emulsion.
Silane connection accelerator belongs to one kind of silane coupler, is that a class has the low molecule of special construction siliconated
Compound.In its molecule, while having the reactive group that can be combined with inorganic material and organic material (such as synthetic resin).This
Invention is exactly this characteristic by silane connection accelerator by PU emulsions and PA emulsions, polyvinyl acetate emulsion, these performances
Widely different material coupling is got up, to improve the performance of composite and increase adhesive strength so that obtain excellent performance,
Reliable advanced composite material (ACM).
Advantages of the present invention has：
1., suitable for the application of indoor wall, it is particularly suitable for allergic constitution crowd and uses.1st, fire protection flame retarding, it is anti-up to national A grades
Fiery standard；2nd, it is nonpoisonous and tasteless, without harmful substances such as formaldehyde, benzene, without heavy metal, radiationless 3, acid and alkali-resistance；4th, air permeable waterproof,
Do not ftracture, non-scale is non-foaming；5th, color is soft, non-reflective, and color is various, available；
2. irradiated suitable for various climatic environments, UV resistant, color is lasting, long service life；7th, maintain simple, maintenance expense
With low；
3. instant invention overcomes some shortcomings of single polyurethane or single polyacrylic resin, such as stability, white thickening
The gloss retention of property and film is poor, and solid content is high, and range of application is not wide etc..Polyurethane and polyacrylic resin, polyvinyl acetate emulsion
There is complementation in nature.This composite coating has had both the advantage of the two, and with wear-resisting, corrosion-resistant and light, softness has
Elasticity, water resistance and mechanical mechanics property are good, the characteristic such as weatherability is good.
