| 摘 要： | 氟橡胶(FKM)具有耐高温、耐油及耐多种化学药品侵蚀的特点,但加工性能不好,本文通过氟橡胶与氯醚橡胶(CO)并用改性,结果表明,CO的加入改善了FKM的加工性能,当CO并用份数少于40份时,FKM为连续相,CO超过40份时,CO转变为连续相。FKM/CO并用胶需用双硫化体系硫化,当FKM采用AF/BPP硫化时,CO采用NA-22/MgO或TCY/MgO/CaCO3硫化体系,并用胶有较好的硫化效果。

| Abstract: | FKM has extremely significant properties for heat resistance and oil resistance, but poor processing properties. By means of blending with CO rubber, FKM processing properties can be improved obviously. Investigation results show that when CO content is less than 40wt% , FKM keeps continuous phase, while CO content is large than 40wt% , CO will be continuous phase. FKM/CO blends need bi-curing system for their vulcanization. When AF/BPP as curing agent for FKM, NA-22/MgO or TCY/MgO/CaCO3 as CO curing agent, FKM/CO blends have perfect vulcanization properties. |
