Abstract: Silicone rubber with high temperature, low temperature, moisture, insulation, anti-aging excellent performance, are widely used in many areas of the national economy, in particular silicone rubber. As the pure silicone rubber poor mechanical properties, so it has a value adding reinforcing filler. Commonly used silica as a reinforcing filler, in order to reduce costs, people look for other cheap and easy to get a filler to replace, but mostly only as extender without reinforcement properties. The subject comes from actual production, the current increase the strength of silicone rubber and more focused on filling research and study on the amount of crosslinker little less, is not conducive to either plant or a research worker to room temperature vulcanized silicone understanding of rubber, which makes it inevitable blind study to study, or modified silicone rubber. The aim of this in different types of silica and the same model with different amount of silica on the mechanical properties of rubber vulcanization made after the evaluation, and use different types of cross-linking agent (methyl 3-acetoxy-silane) and the same amount of different models crosslinking agent on the mechanical properties of rubber to do analysis, by these two judges to select the best point to reproduce, as a basis to improve room temperature mechanical properties of silicone rubber.
