反式异戊橡胶釜内合金在轿车轮胎带束层中的应用
Study of trans-1, 4-polyisoprene rubber alloys as belts stocks in passenger car radical tire
摘要
Abstract
The crystallization behavior,mechanical properties,processing characteristics of two kinds of trans-polyisoprene rubber alloys(TPIR) 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 TPIR-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.TPIR-05 vulcanizate has good adhesion with steel.Using 10-30 phr TPIR to substitute NR in tire belts recipes,NR/TPIR vulcanizate showed satisfied comprehensive properties,such as excellent tensile strength,modulus,hardness,tear strength,adhesion with steel,hot-air aging resistance.NR/TPIR vulcanizates showed lower rolling resistance because of the good compatibility between NR with TPIR.Carbon black also dispersed uniformly in NR/TPIR vulcanizates.关键词
