摘要
为了探究乙丁橡胶(EBT)和三元乙丙橡胶(EPDM)的综合性能,通过对比实验研究了乙烯含量与第三单体含量相近的EBT和EPDM的综合性能。结果表明,当EBT和EPDM的乙烯含量相近时,两者都具有较好的抗压变性以及回弹性;EBT的拉伸强度相对较低,但具有更好的抗撕裂性,并且自黏性是EPDM的两倍;EBT与EPDM耐高温性优异,但EBT的耐热空气老化后力学性能变化率略大;EBT的耐低温性优于EPDM。
In order to explore the comprehensive performance of ethylene butadiene rubber(EBT)and ethylene propylene diene monomer rubber(EPDM),the comprehensive performance difference of EBT and EPDM with similar ethylene content and third monomer was studied.The results show that when the ethylene content is similar,the compressive denaturation and resilience of EBT and EPDM are excellent;the tensile strength of EBT is realtively lower and the tear resistance of EBT is better.Moreover,the self-adhesion of EBT is twice that of EPDM;EBT and EPDM have excellent high temperature resistance,but the mechanical properties of EBT after thermal air aging have a slightly larger change rate;the low temperature resistance of EBT is better than that of EPDM.
