application field | 1.3-(2,3-epoxypropoxy) propylmethyldiethoxysilane is mainly used in unsaturated polyester composites, which can improve the mechanical properties, electrical properties and light transmission properties of the composites, especially the wet properties of the composites. 2. The wet mechanical strength and electrical properties of glass fiber reinforced composite materials can be improved by infiltrating glass fiber (containing the coupling agent). 3. In the wire and cable industry, the coupling agent was used to treat the clay filled with peroxide crosslinked EPDM system, which improved the consumption factor and specific inductance capacitive reactance. 4.3-(2, 3-epoxypropoxy) propylmethyldiethoxysilane is copolymerized with vinyl acetate and acrylic acid or methacrylic acid monomer. These polymers are widely used in coatings, adhesives and sealants to provide excellent adhesion and durability. |
background and overview | organosilicon compounds and organosilicon materials made from them have many varieties and excellent performance, and have been widely used in industrial and agricultural production, emerging technologies, national defense and military industries and other fields. The hydrosilylation reaction is one of the most important methods to generate Si-C bonds in organosilicon chemistry. Many organosilicon monomers and polymers containing organic functional groups can be synthesized through the hydrosilylation reaction. Silane coupling agent is a kind of low molecular organosilicon compound with a special structure. Its general formula is RSiX3, where R represents amino group, mercapto vinyl group, epoxy group, chloropropyl group, cyano group, methacryloxy group and other groups, these groups and different matrix resins have strong reaction ability, X represents the group that can be hydrolyzed, such as halogen, alkoxy group, acyloxy group, etc. Therefore, silane coupling agent can interact with both hydroxyl groups in inorganic substances and long molecular chains in organic polymers, thus coupling two materials with different properties to achieve the purpose of improving the performance of biological materials. |
