摘　　要：研究氯化聚乙烯橡胶(CM)和高密度聚乙烯(HDPE)对废轮胎胎面胶粉再生橡胶性能的影响。结果表明:再生橡胶的门尼粘度随着CM用量的增大而降低,随着HDPE用量的增大而提高;交联密度随着CM或HDPE用量的增大而逐渐增大;拉伸强度随着CM或HDPE用量的增大而逐渐提高,拉断伸长率随着CM或HDPE用量的增大基本呈先增大后减小趋势;添加CM的再生橡胶的拉伸断面相对平整,断层更均匀,CM用量为8份时,再生橡胶的综合性能较佳。The effects of CM and HDPE on the properties of reclaimed rubber from tread rubber powder were investigated. The results showed that,with the addition level of CM increasing,the Mooney viscosity of reclaimed rubber decreased,and with the addition level of HDPE increasing,the Mooney viscosity of reclaimed rubber increased.With the addition level of CM or HDPE increasing,the crosslink density and tensile strength increased,and the elongation at break increased at first and then decreased. The tensile fracture of reclaimed rubber filled with CM was relatively smooth and more uniform,and the optimized addition level of CM was 8 phr.
