摘要]研究了反式异成橡胶内合金(TPIR)的生胶结晶性能、力学性能和加工性能,及其在轿车轮胎带東层中的应用。
验结果表明、TPIR的玻璃化转变温度、结晶熔融爚、牛胶强度和硬度均低于反式异戊橡胶。丁二烯单体单元的含量分别
为4.8%(x)和10.5%(x)的TPIR-05和PIR-10在宽应变、宽率和宽温度范围内均具有良好的加工性能。相比天然橡胶
(NR)硫化胶,TPIR硫化胶具有更好的撕裂强度、定伸应力、硬度和耐老化性能,TPIR-05伉化胶具有很好的钢丝黏合性能。
将10~30份TPHR取代NR应用于轮胎带東层胶料,NR/TPIR并用硫化胶同时兼备优异的拉伸强度、定伸应力、硬度、撕裂
强度、钢丝黏合性能及耐老化性能。NR与TPIR相容性较好, NR/TPIR并用硫化胶的滚动阻力较低。炭黑在NR和 NR/IPIR
并用硫化胶中均具有良好的分散性。含TPIR的轮胎带束层胶料具有更优异的综合性能。

Abstract The crystallization behavior, mechanical properties, processing characteristics of two
kinds of trans-polyisoprene rubber alloys(T PIR)and their application in tire belts were investigated
Compared with trans-polyisoprene raw rubber, TPIRS showed lower glass transition temperature
crystallization melting enthalpy, strength and hardness. TPIR-05 and TPTR-10, in which the
content of butadiene are 4. 8%(x)and 10. 5%(x), respectively, have good processability in a wide
range of strain, frequency and temperature. Compared with nature rubber(NR)vulcanizate, TPIR
vulcanizate showed improved tear strength, high modulus and excellent hot-air aging resistance
TPTR-05 vulcanizate has good adhesion with steel. Using 10-30 phr TPTR to substitute NR in tire belts
recipes, NR TPIR vulcanizate showed satisfied comprehensive properties, such as excellent tensile
