Abstract：This experiment prepared the room temperature vulcanizing(RTV)two-component dealcoholization condensation liquid silicone rubber by the planetary mixing method. The effects of powder-liquid ratio and 107 adhesive viscosity on the properties of silicone rubber were discussed. Moreover the impact of coupling agent and organotin catalyst on silicone rubber properties was elaborated. The results showed that the mechanical properties and the surface hardness of silicone rubber were more affected by the ratio of powder to liquid in component A,and the viscosity of 107 adhesive had a significant effect on the contact surface drying time,mechanical properties and other properties of silicone rubber. In component B,the silane coupling agent has a great influence on the curing and shear strength of the silicone rubber. With the increase of the catalyst dosage,the surface dry rate of the silicone rubber increases at first and remains constant at later stage.
