A one component RTV silicone rubber is prepared with α,ω-dihydroxy polydimethylsiloxane as the base glue,calcium carbonate filler as reinforcement,and some certain content of crosslinking agent,coupling agent and catalyst.The effects of three kinds of silane coupling agents and compounded coupling agents on the vulcanization properties,physical properties,bonding effect and storage stability of silicone rubber are investigat-ed.The test results show that the number of active functional groups in the silane coupling agent has a great influence on the vulcanization,adhesive properties and storage stability of the silicone rubber.The coupling agent has a certain negative effect on the storage property of silicone rubber.Using 1～2 portions of compounded coupling agent as raw material will achieve the best comprehensive performance of the prepared silicone rubber.
