SSBR2535基本性能的研究

探讨国产新型充油高乙烯基溶聚丁苯橡胶SSBR2535的基本性能。结果表明，与国外同类产品相比，SSBR2535生胶门尼粘度低；混炼胶的门尼松弛面积小，硫化速度快，强度高；硫化胶定伸应力和拉伸强度低，拉断伸长率和撕裂强度高，耐疲劳性能好，耐热老化性能略差，滚动阻力、抗湿滑性能和耐磨性能平衡性好，可在轮胎工业中推广应用。;The basic properties of new domestic oil-extended HV-SSBR2535 were investigated.The results showed that when compared to the improved counterparts，SSBR2535 possessed lower Mooney viscosity of green rubber，smaller relaxation area，higher vulcanization rate and higher strength of mix，and lower modulus and tensile strength，higher elongation at break and tear strength，better fatigue resistance，somewhat poorer thermal aging property，and well balanced rolling resistance，wet traction and abrasion resistance of vulcanizate；and SSBR2535 was worth popularizing in tire industry
