摘　　要：以HNBR和FKM两种性能优异的橡胶材料在90:10(质量分数)的比例共混并用,通过分别改变硫化剂含量、炭黑N220和白炭黑含量、硫化时间、硫化温度4个条件,得到当硫化剂含量为6质量分数,炭黑N220和白炭黑含量为65质量分数、硫化时间为60min,硫化温度为165℃时的实验方案最优。由此实验方案制得的HNBR/FKM橡胶密封筒用料的硬度可达到93HD,拉伸强度68.58MPa,断裂伸长率228%,压缩强度58.94MPa。Two kinds of rubber material （HNBR and FKM） with excellent properties in 90：10 （w） ratio were blended and used. By respectively changing the content of curing agent （co）, carbon black N220 and silica （w）content, curing time（min）, curing temperature（℃ ）, the most superior experimental condition had been obtained when the curing agent content was 6 wt%, carbon black N220 and silica content 65w, the curing time 60min, the curing temperature 165℃. The hardness of the HNBR/FKM rubber sealing sleeve prepared by the experimental scheme can reach 93HD, tensile strength 68.58MPa, elongation at break 228%, compressive strength 58.94 MPa.
