Silane coupling agent modification
That's able to enhance the wear resistance and high temperature resistance of silica gel by changing its chemical structure and composition.
Principle: The silanol groups on the surface of silica gel are used to undergo hydrolysis and polycondensation reactions with silane coupling agents with different functional groups. Silane coupling agents act as a bridge to connect inorganic components with organic components by chemical bonds, thereby enhancing the interaction between the two.
Effect: Through chemical modification, the surface polarity of silica gel can be changed from hydrophilic to hydrophobic, enhancing its compatibility with organic solvents or organic monomers and improving its dispersibility in organic matrices. In addition, the mechanical strength, impact resistance, conductivity, heat resistance, oxidation resistance, wear resistance and other properties of silica gel can also be improved.
