摘要

采用不同份数（0~15phr）的环保芳烃油（TDAE）改性反式-1，4-丁二烯-异戊二烯共聚橡胶（TBIR），研究了充油份数对TBIR胶、TBIR混炼胶及硫化胶性能的影响。结果表明，随充油份数的增加，TBIR胶和TBIR混炼胶的门尼粘度降低，混炼胶挤出物外观形貌改善，Payne效应减弱。充油改性TBIR硫化胶（5~10份TDAE）耐裂口引发性提高23倍以上，损耗降低，撕裂性能提高，硬度下降，拉伸强度及定伸模量基本不变；TEM测试表明，充油改性TBIR硫化胶的炭黑分散性改善；DSC测试表明，硫化胶中存在TBIR的微弱结晶熔融峰。环保芳烃油的充油份数为10phr时，胶料综合性能最好。

Abstract

The trans-1

4-poly(butadiene-co-isoprene) rubber (TBIR) was modified by environment-friendly aromatic oil (TDAE) with different weight fraction (0

15 phr) and the effects of extending oil on the TBIR rubbers

TBIR compounds and TBIR vulcanizates were studied in details.The results showed that with the increase in extending oil

the Mooney viscosity of the TBIR rubbers and TBIR compounds decreased

as well as improved extrusion appearance and weakened Payne effect of the oil extended TBIR compounds. The TBIR vulcanizates with 5~10phr oil presented outstanding 1st crack resistance (23 times higher) than that of the TBIR vulcanizate

as well as the reduced loss factor

increased tear strength

lower hardness and almost unchanged tensile strength and modulus. TEM test showed that the carbon black dispersion in the oil extended TBIR vulcanizates was improved. DSC measurement indicated the existence of crystalline domains in the TBIR vulcanizates. The TBIR vulcanizate with 10phr extending oil possessed the satisfied performances.
