通过硅橡胶海绵型芯的研制,研究了发泡剂、补强剂和硫化剂对海绵硅橡胶性能的影响。结果表明,研制的海绵型芯与型材复合可满足密封性能要求。 Through the development of silicone rubber sponge core, the effects of foaming agent, reinforcing agent and vulcanizing agent on the properties of sponge silicone rubber were studied. The results show that the developed sponge core and profile composite can meet the sealing performance requirements.
