不同粒径和结构度炭黑填充集成橡胶的性能研究

研究不同粒径和结构度炭黑填充集成橡胶（SIBR）的性能。结果表明：高结构度的BL系列炭黑和大粒径的炭黑N774均使SIBR胶料的焦烧时间和硫化时间延长；随着炭黑结构度的提高，胶料的门尼粘度和交联密度增大；结构度最高的炭黑BL302填充硫化胶的定伸应力最大，耐老化性能最好；结构度大、粒径小的炭黑BL201填充胶料的Payne效应最强，生热也较大；在0 ℃下炭黑N774，N660，N550，N330，N220，BL201，BL101，BL302填充硫化胶的损耗因子依次减小，抗湿滑性能下降。;The performance of the SIBR filled with carbon black with different particle sizes and structures were studied. With high structure BL series carbon black or large particle size carbon black N774，the scorch time and optimum curing time of the SIBR compound were prolonged.With the increase of the structure of carbon black，the Mooney viscosity and crosslink density of SIBR compound increased.The modulus of the SIBR vulcanizates filled with carbon black BL302 which possessed the highest structure was the highest and its properties after aging was the best.The Payne effect of the compound filled with carbon black BL201 with high structure and small particle size was the strongest， and the heat build-up was also higher.At 0 ℃，the loss factor of the vulcanizates filled with carbon black N774，N660，N550，N330，N220，BL201，BL101，BL302 reduced sequentially，and the wet skid resistance was also decreased in that order
