摘要：探讨国产溶聚丁苯橡胶(SSBR)T2530的基本性能。结果表明，与乳聚丁苯橡胶(ESBR)1712E和1712相比，SSBR生胶的重均相对分子质量略小，数均相对分子质量稍大，相对分子质量分布较窄，纯胶含量较高；混炼胶的门尼粘度较高，硫化速度较快，焦烧时间略有缩短，但加工工艺性能差别不大；硫化胶的300%定伸应力和拉伸强度略低(适当调整炭黑用量可使300%定伸应力达到ESBR的水平)，弹性较好，滚动阻力较低。

Abstract:The basic properties of domestic SSBR T2530 were investigated.The results showed that when compared to ESBR1712E and 1712,SSBR T2530 possessed smaller weightaverage molecular weight(w),greater numberaverage molecular weight(n),narrower molecular weight distribution,and higher content of SSBR;its mix also possessed higher Mooney viscosity and vulcanization rate，shorter scorch time,and similar processing properties;its vulcanizate showed lower stress at 300% strain and tensile strength (but stress at 300% strain could be enhanced to the level of ESBR by adjusting the proportion of carbon black),better elasticity,and lower rolling resistance.
Keywords:SSBR;ESBR;oilextended rubber;rolling resistance

摘要：研究液体聚异戊二烯橡胶（LIR）等量部分替代NR在轿车轮胎三角胶中的应用效果。结果表明，使用5份LIR等量部分替代NR可以在对胶料物理性能影响不大的情况下降低门尼粘度，提高炭黑分散性，节省混炼能耗，改善挤出、成型和粘合工艺性能，减少由于半成品挺性大造成的胎圈窝气现象，成品轮胎的高速性能和耐久性能基本不变。
