摘要
研究增塑剂种类和用量以及炭黑种类对乳聚丁苯橡胶(ESBR)性能的影响。结果表明:随着增塑剂用量的增大,硫化胶的物理性能均下降;在相同增塑剂用量下,与加入芳烃油的硫化胶相比,加入环烷油或环保芳烃油(TDAE)的硫化胶的压缩疲劳温升较小。随着应变和增塑剂用量的增大,胶料的Payne效应减弱;在相同增塑剂用量下,加入芳烃油的胶料Payne效应最强。在相同粒径炭黑胶料中,加入TDAE的胶料拉伸强度与撕裂强度最大,压缩疲劳温升最小;加入芳烃油与炭黑N220、N330的胶料Payne效应较强。
The influence of type and addition level of plasticizer and type of carbon black on the properties of ESBR was investigated. The results showed that, as the addition level of plasticizer increased, the physical properties of vulcanizates decreased. At the same addition level of plasticizer, the temperature rise in dynamic compression of naphthenic oil or environment-friendly aromatic oil （TDAE） filled vulcanizate was lower than that of aromatic oil filled vulcanizate. As the strain and addition level of plasticizer increased, the Payne effect of compounds was weakened. At the same addi- tion level of plasticizer, the Payne effect of aromatic oil filled compounds was the strongest. In the com- pounds filled by carbon blacks with the same particle size,the TDAE filled compounds possessed the highest tensile strength and tear strength,and the lowest temperature rise in compression. The Payne effect of aromatic oil and carbon black N220 or N330 filled compounds was stronger.
