不同炭黑对溶聚丁苯橡胶性能的影响

研究不同炭黑对溶聚丁苯橡胶（SSBR）性能的影响。结果表明：在密炼（一段混炼）过程中炭黑N330填充SSBR胶料的温度和功率均较高，不同炭黑填充SSBR胶料的粘-切依赖性大致相同；炭黑粒径越小、结构度越高，其填充SSBR胶料的Payne效应越显著；炭黑SP5000填充SSBR胶料的焦烧时间最长，炭黑N115，N234，N330和N550填充SSBR胶料的硫化速率稍快；粒径较小的炭黑填充SSBR硫化胶的物理性能和耐磨性能较优，但压缩温升较高；粒径相近而结构度较高的炭黑填充SSBR硫化胶的物理性能优于结构度较低的炭黑填充硫化胶；粒径较大的炭黑填充SSBR硫化胶的抗湿滑性能较好和滚动阻力较低，炭黑N774填充SSBR硫化胶的抗湿滑性能最好，且滚动阻力最低。;The effects of different carbon black on the properties of solution polymerized styrene-butadiene（SSBR） were studied.The results shown that，both the temperature and power of SSBR compound filled with carbon black N330 were higher in mixing（one stage mixing） process.The viscosity-shear rate relationships of SSBR compound filled with different carbon black were almost the same.The smaller the particle size and the higher structure of carbon black，the more obvious the Payne effect of corresponding filled compound.The scorch time of SSBR compound filled with carbon black SP5000 was the longest，the curing rate of SSBR compound filled with carbon black N115，N234，N330 and N550 was slightly faster，the physical properties and wear resistance of SSBR vulcanizate filled with carbon black with smaller particle size were better，but the compression temperature rise was higher.The physical properties of SSBR vulcanizate filled with carbon black with similar particle size and higher structure degree were better than those filled with carbon black with lower structure degree.The SSBR vulcanizate filled with carbon black with larger particle size had better wet sliding resistance and lower rolling resistance，while the SSBR vulcanizate filled with carbon black N774 had the best wet sliding resistance and the lowest rolling resistance
