不同炭黑填充溶聚丁苯橡胶的性能研究

研究不同粒径炭黑对溶聚丁苯橡胶（SSBR）性能的影响。结果表明：结构度高的炭黑填充SSBR混炼胶的加工性能较差；高结构度BL系列炭黑填充SSBR硫化胶的定伸应力、拉伸强度、撕裂强度和补强因子均比低结构度炭黑N220和N330填充硫化胶高；炭黑BL201，BL101，BL302，N220和N330填充SSBR混炼胶的剪切储能模量和剪切耗能模量依次减小，BL系列炭黑填充SSBR硫化胶在0 ℃下的损耗因子较小，抗湿滑性能较差。;The influence of carbon blacks with different particle size on the properties of SSBR was investigated.The results showed that，the processing properties of the SSBR filled with carbon black with high structure were poor.The modulus，tensile strength，tear strength and strength factor of the SSBR vulcanizates filled with high structure BL series carbon black were higher than those with low structure carbon black N220 and N330.The storage modulus and loss modulus of the compounds decreased in sequence with carbon black BL201，BL101，BL302，N220 and N330.At 0 ℃，the loss factor of the SSBR vulcanizates filled with BL series carbon black was lower，and the wet skid resistance was poor
