Latex is how to classify?

发布日期:2013/8/29

Classified according to the main film-forming substances , the main domestic varieties of fluorocarbon paint coatings , silicone-acrylic paints , acrylate and other copolymers, polyvinyl acetate , VAE ( vinyl acetate - ethylene copolymer ) type, and ( chloro ethylene - vinyl chloride copolymer ) class .

Fluorocarbon coating is a very good paint , fluorine atoms with high electronegativity and small atomic radius , fluorine resin structure CF bond in several carbon compounds in the highest bond energy , so that it has the best weather resistance , high hardness of the fluororesin film , the surface energy is low, and thus an excellent stain resistance , a fluorine resin coating is called super durable coatings .

Silicone-acrylic resin emulsion paint is more high-grade paint used . Researchers silicone modified acrylic emulsion research and development , starting from the molecular design and colloidal form design , the introduction of the silicone acrylate emulsion polymerization using a range of the most advanced technologies in the polymerization process , such as core-shell polymerization technology , soap-free polymerization and cross-linking technology control , etc., in order to give a series of unique features such emulsion and paint. Since the silicone oligomer and the polymerization of acrylic acid monomer , thereby forming a stable polymer of a special structure , its permeability , permeability, water resistance, weather resistance, stain resistance , and low toxicity etc. superior general of acrylic resin , and both excellent characteristics of silicone and acrylic resin , with water as the dispersion medium , safe and nontoxic. Concrete surface with the resin coating formulated for all types of buildings, masonry cement mortar base surface and the base surface of the external walls and floor , roof , and its moisture-proof , anti-aging , high adhesion and gloss and color retention properties were very prominent ; acrylic architectural decoration industry and is currently widely used , styrene and vinyl acetate-acrylate coatings compared to the excellent performance of the product set polyacrylate and silicone in one, has excellent film forming, high adhesion, high highly water contamination resistance, high temperature resistance and superior weather resistance , but also has self-cleaning environmental powerful, is to reach the international level of new products .

Acrylate copolymer and styrene- class main varieties - acrylic (acrylic ) paint , vinyl acetate - acrylate ( ethylene propylene ) latex and acrylic ( acrylic ) paint and so on . Meanwhile, in which there are several types of plain latex paint , semi-gloss latex paint and Hu et . Acrylic emulsion recent years, the use of a broader construction market is mainly used for exterior walls, has better performance , such as durability , decorative, protective , able to reach the current one would expect results, but its waterproof performance should be improved . Acrylic emulsion styrene-acrylic and vinegar because it is easy to produce , " yellowing , chalking ," and color retention period is generally not long, so mainly for interior walls.

China is vigorously promoting the use of the environmental health of the new architectural coatings , strongly recommend the use of fluorocarbon coatings and silicone-acrylic paint ; but due to the fluorine resin and other raw materials with respect to the use of more expensive silicone resin . So silicone-acrylic resin emulsion paint is more high-grade paint used .
