中文摘要:
      采用正交试验法研究硫黄、防老剂4010NA、促进剂TMTD、促进剂NS以及增塑剂A的用量对三元乙丙橡胶(EPDM)密封圈硫化胶拉伸强度、拉断伸长率、拉断伸长率保持率和压缩永久变形的影响。结果表明:硫黄用量对EPDM密封圈硫化胶各项性能的影响最为显著;当硫黄、防老剂4010NA、促进剂TMTD、促进剂NS和增塑剂A用量分别为0.5,2,1.5,1和2份时,硫化胶的耐压缩永久变形性能最好。
英文摘要:
      The effect of the addition level of sulfur,antioxidant 4010NA,accelerator TMTD,accelerator NS,plasticizer A on the tensile strength,elongation at break and its retention,compression set of EPDM vulcanizate for sealing ring was investigated by using orthogonal experiment design method. The results showed that,the addition level of sulfur was the most significant factor.When the addition level of sulfur,antioxidant 4010NA,accelerator TMTD,accelerator NS and plasticizer A was 0.5,2,1.5,1 and 2 phr respectively,the permanent compression deformation resistance was the best.
