采用转矩流变仪研究EPDM再生胶的制备及性能影响因素

Study on Preparation and Properties Influencing Factors of Reclaimed EPDM by Torque Rheometer

采用转矩流变仪对废旧三元乙丙橡胶(EPDM)进行再生,考察再生温度、再生时间及活化剂品种和用量对EPDM再生胶胶料性能的影响。结果表明:在试验范围内,再生温度为170℃、再生时间为10 min、活化剂420用量为1份时,EPDM再生胶胶料的综合性能较好。

The waste EPDM was reclaimed with the torque rheometer, the influence of reclaim temperature, reclaim time and activator variety and addition amount on reclaimed EPDM compound properties was investigated. The results showed that in the test range, the reclaimed EPDM compound has better comprehensive properties when the reclaim temperature was 170℃, the reclaim time was 10 min, the activator 420 addition amount was 1 phr.
