3种增塑剂对氯磺化聚乙烯橡胶性能的影响

Effects of Three Plasticizers on Properties of Chlorosulfonated Polyethylene Rubber

研究增塑剂TOTM,TP-95和TP-90B对氯磺化聚乙烯橡胶性能的影响,并与增塑剂DOP进行对比。结果表明:加入增塑剂TP-95和TP-90B的胶料t90缩短,而加入增塑剂TOTM的胶料t90延长;加入增塑剂TP-90B的硫化胶物理性能较好;增塑剂TOTM具有更好的热稳定性;加入增塑剂可提高硫化胶的低温脆性,增塑剂TP-95硫化胶的低温脆性最佳;加入增塑剂会降低硫化胶的阻燃性能,增塑剂TP-90B硫化胶的阻燃性能下降程度最小。

The effects of plasticizer TOTM,TP-95 and TP-90B on the properties of chlorosulfona- ted polyethylene rubber were investigated,and compared to plasticizer DOP. The results showed that, the tg0 of compound was shortened with TP-95 or TP-90B, but extended with TOTM; the physical properties of vulcanizate with TP-90B were better; and vulcanizates with TOTM had better thermal stability. The low-temperature brittleness of vulcanizate was improved by using plasticizers,and TP-95 presented the best result. The flame retardant property of vulcanizate was decreased by using plasticizers,and the smallest decrease was with TP-90B.
