Material is low using elastic acrylic ester copolymerization object lotion, VAE lotion, the cold mixed copolymer emulsion of waterproof silicone materials as base-material
The heat-barrier materials such as the empty glass microballoon of thermal coefficient, hollow ceramic microballon, the reflecting materials such as titanium dioxide, zinc oxide, ultra-fine mica
It is the water-borne acrylic type water-proof heat-insulating paint of pigments and fillers with corrosion resistant blanc fixe, wollastonite etc..However, this aqueous third
Olefin(e) acid type water-proof heat-insulating paint either adhesion or transparency is not all suitable for building glass.
For another Chinese patent application, a kind of No. 102181208A revealed reflection heat insulation coating for outer wall is disclosed, it is described
Coating composition includes: filmogen 40%-50% by weight percentage；Pigments and fillers 29%-38.5%；Monocrystalline silicon powder l%-
1.5%；Auxiliary agent 3%-5%；Deionized water 10%-22%；The filmogen includes water-base fluorocarbon emulsion and elastic emulsion；Institute
Stating pigments and fillers includes one of rutile type titanium white, mica powder, diatomite, ultrafine heavy calcium or a variety of；The auxiliary agent includes
One of dispersing agent, levelling agent, defoaming agent, preservative, thickener, coalescing agent, antifreezing agent are a variety of.However, this outer
Wall heat-reflecting insulating coating either adhesion or transparency is not all suitable for building glass.
