| application | suitable for adhesives such as epoxy resin, phenolic resin, urea-formaldehyde resin, polyurethane, polyamide, melamine, polyethylene butyral, etc. It can be used as an adhesion promoter, surface modifier, cross-linking agent and dispersant, and is mainly used to improve the adhesion and compatibility of inorganic mineral powder materials and fibers to high molecular polymers (resins) and resin coatings. Adhesion and water resistance of inorganic substrates. Including engineering rubber and plastic material modification, paint, coating, ink, casting resin, adhesive, sealant, glass fiber, abrasive and other industries. |
| production method | (1) synthesis of γ-aminopropyl triethoxysilane trichlorosilane, ethanol and solvent benzene are added to a stirred reaction kettle, heated under stirring for reaction, distilled after the reaction, distilled out the solvent and recovered, and the remaining product is triethoxysilane. The synthesis reaction formula is as follows: The addition reaction of triethoxysilane and allylamine or the reaction of chloropropyltriethoxysilane with amine or ammonia is used to prepare γ aminopropyltriethoxysilane: (2) Synthesis of γ-Urea-propyltriethoxysilane Add γ aminopropyltriethoxysilane and ethyl carbamate to a stirring reactor, use dibutyltin oxide as a catalyst, and heat under stirring for the reaction, urea substituted silane can be prepared. |
