新型耐低温氟树脂的合成及性能研究

Synthesis of and Properties of Low Temperature Fluororubber

以偏氟乙烯(VDF)、六氟丙烯(HFP)和三氟丙基二甲基硅烷基丙烯醚(第三单体)为原料,采用乳液聚合法合成三元氟橡胶生胶,将生胶与补强剂、结构控制剂以及交联剂混炼后,硫化为含特殊第三单体的耐低温氟橡胶。研究了引发剂类型、第三单体含量、聚合压力和聚合温度对制备得到的耐低温氟橡胶性能的影响并进行了相应的分析。

VDF、HFP and trifluoropropyldimethylsilylpropenylether were used as the raw material to prepare the low temperature fluororubber. In this paper,the influence of the initiator type,the third monomer content,polymerization pressure and polymerization temperature on the fluororubber performance,especially the low temperature resistance were studied.
