What chemicals added to the PVB resin powder can be diluted into a transparent liquid?
PVB film is a translucent film, the plasticized polyvinyl butyral resin by a polymer material plasticizing agent for extrusion molding. The appearance of translucent film, no impurities, smooth surface, there is a certain roughness and good softness, cohesion and good for inorganic glass with a transparent, heat resistance, cold resistance wet, high mechanical strength, is currently the world's best manufacturing adhesive material layer, safety glass, while building curtain wall, window, tent, recruit bank counter, prison has a wide application window, screen of steel furnace and various bullet proof glass construction field.
Polyvinyl butyral (Polyvinyl butyral) PVB.... PVB resin itself contains many hydroxyl (OH) radicals, with some thermosetting resin (Thermosetting resin) (Cross linking reaction produced a bridging reaction) to improve chemical resistance and film hardness and excellent coating properties. High transparency (Transparent), (elastic), elastic toughness (Toughness), alkali resistance, oil resistance and flexibility, impact resistance and low temperature. Because of its special chemical structure, so there is a strong combination of glass, metal, ceramic, plastic, leather and wood.
1) PVB resinPVB intermediate membrane is mainly made of PVB resin..PVB resin is a macromolecule compound obtained by the reaction of polyvinyl alcohol and polyvinyl alcohol under the catalysis of strong acidPVB resin is non-toxic, odorless, non corrosive, non flammable, has good light transmittance, insulation, weather resistance, abrasion resistance, water resistance, oil resistance, aging resistance, adhesive and transparent special properties of inorganic and organic glass. Sandwich materials can be used as safety glass, and can be made transparent other materials used.2) plasticizersPlasticizer 3G8 used in PVB intermediate film has good phase solubility with PVB resin, and has good cold resistance, heat resistance and so on3) additivesIn addition to the above two main raw materials, PVB intermediate membrane, in order to adjust the adhesive force, improve the weather resistance and isolate ultraviolet radiation, also added a relay regulator, antioxidant, UV absorbers and other additives
