Abstract
The effect of addition level of silicone resin on the heat resistance of two-component room temperature vulcanized silicone rubber was investigated.The results showed that,as the addition level of silicone resin increased,the Shore A hardness,tensile strength and elongation at break of silicone rubber tended to increase,and the heat resistance increased at first and then decreased.When the addition level of silicone resin was 8 phr,the best tensile property and aging property of silicone rubber were obtained.When the addition level of silicone resin was 6 phr,the best heat resistance of silicone rubber was achieved.
