摘　　要：研究炭黑N330/N990用量比对过氧化物硫化体系氟橡胶物理性能和耐热氧老化性能的影响,并与双酚A硫化体系氟橡胶进行比较。结果表明:随着炭黑N330/N990用量比增大,过氧化物硫化体系氟橡胶的物理性能和耐热氧老化性能提高,压缩永久变形明显减小;当炭黑N330/N990用量比较大时,氟橡胶的物理性能变化不大;与双酚A硫化体系氟橡胶相比,过氧化物硫化体系氟橡胶的硬度和定伸应力较小,拉伸强度和拉断伸长率较大,耐热氧老化性能较好。Effect of the amount ratio of carbon black N330/N990 on the physical properties and thermal oxidative aging resistance of fluoro rubber cured with peroxide curing system was investigated,and compared with that cured with bisphenol A curing system. The results showed that,with the increase of the amount ratio of carbon black N330/N990,the physical properties and thermal oxidative aging resistance of fluoro rubber cured with peroxide curing system were improved,and the permanent compression set decreased significantly. However,when the amount ratio of carbon black N330/N990 was high,the physical properties changed little as it further increased. Compared with fluoro rubber cured with bisphenol A curing system,the hardness and modulus of fluoro rubber cured with peroxide curing system were lower,tensile strength and elongation at break were bigger,and thermal oxidative aging resistance was better.
