| Abstract: |
| M-5 fumed silica was surface modified by diffferent silane coupling agent to enhance the compatibility of silicone rubber. The change of surface status about fumed silica before and after treatment was characterized by FT-IR. The kind and amount of silane coupling agent affect surface performance of fumed silica were compared and analysised, the mechanical properties of room temperature vulcanizable ( RTV) silicone rubber filled by modified fumed silica was also tested. The FT-IR results show that silane coupling agent molecular is grafted on the surface of fumed silica, the best effect treatment of silane coupling agent is vinyltrimethoxysilane, the tensile strength of silicone rubber wluch blend 15% fumed silica is l. 5MPa, the adhesive strength reaches l. 3MPa. |
