摘要
研究促进剂品种和用量对三元乙丙橡胶(EPDM)海绵性能的影响。结果表明:在一定的发泡体系下,硫化速率对EPDM海绵的结构和性能影响很大;采用发泡剂AC/OBSH/尿素并用体系,当硫化体系及用量为硫黄1.2,促进剂TMTD 1,促进剂M 0.8,促进剂PZ 1.2,促进剂BZ 1.5时,所得EPDM海绵呈微孔结构,泡孔分布均匀,综合性能良好。
The effects of the type and addition level of accelerators on the performances of EPDM sponge were investigated. The results showed that, under certain blowing system, the curing rate had significant influence on the structure and properties of EPDM sponge. It was found that,by using the AC/OBSH/urea blowing system,and the curing system composed of 1.2 phr sulfur, 1 phr accelerator TMTD,0.8 phr accelerator M, 1.2 phr accelerator PZ,and 1.5 phr accelerator BZ, the EPDM sponge possessed a well-distributed cellular structure and had good performance.
