| 中文摘要: |
| 研究再生温度以及石蜡油和氯化聚乙烯橡胶(CM)的用量对废旧三元乙丙橡胶(EPDM)胶粉再生效果的影响。结果表明:再生温度为170 ℃时,废旧EPDM胶粉的再生效果较佳;随着石蜡油用量的增大,再生橡胶的门尼粘度降低,加工性能改善,但物理性能下降,石蜡油用量以10份为宜;随着CM用量的增大,再生橡胶的门尼粘度下降,加工性能改善,物理性能提高,CM用量一般以不小于10份为宜。 |
| 英文摘要: |
| The influence of regeneration temperature and addition level of paraffin oil and chlorinated polyethylene(CM)on the regeneration of wasted EPDM powder was investigated.The results showed that the preferable regeneration temperature was at 170 ℃.With the addition level of paraffin oil increasing,the Mooney viscosity of reclaimed rubber decreased,the processability was improved,but the physical properties decreased,and the proper addition level of paraffin oil was 10 phr.With the addition level of CM increasing,the Mooney viscosity of reclaimed rubber decreased,the processability was improved,physical properties increased,and the addition level of CM was generally not less than 10 phr. |
