Modified silicone
The production of organic resin blending modified silicone resin is usually in toluene or xylene solution of methylphenyl silicone resin, adding alkyd resin, phenolic resin, acrylic resin and other organic resins, and fully mixing is uniform to get the finished product.
Copolymer modified silicone resin is prepared through a series of chemical reactions. Organic resins that can be copolymerized with silicone resin include polyester, epoxy, phenolic, melamine formaldehyde, polyacrylate, etc. The copolymerization of silicone resin can be prepared by many synthetic routes, but the practical industrial production method is the copolymerization of silicone alcohol and organic resin. First by methyl chlorosilane hydrolysis and phenyl chlorosilane monomer, hydrolyzed silicon alcohol solution or concentrate, have been made to it in advance good organic resin prepolymer, and steam to solvent mixture, add octylic acid zinc, zinc naphthenate, such as catalyst, in 150-170 ℃ temperature, condensation reaction under to the reaction material to proper viscosity or reservation, gelation time, After cooling, dissolving with solvent and filtering, the finished copolymerized silicone was obtained.
