The recent development of silicone rubber inhibitor′s mechanical,antiablation and bonding properties were introduced in this paper,which showed that the diameter of the filler in silicon rubber liner had main effect on its reinforcement. The antiablation of silicone rubber liner can be improved both by changing the structure of unvulcanized rubber and adding antiablative fillers,and the bond strength between propellant charge and the liner would be increased largely by coating the primer liquid on the charge surface. It was also shown that the research work should focus on nano-composite fillers and blending technology of silicone with other polymers to improve the reinforcement of silicon rubber liner.
