摘　　要：采用热重分析法表征丁腈橡胶、硅橡胶、氟橡胶和氟醚橡胶的热稳定性,研究在不同升温速率下4种橡胶的失重温度及失重规律,依此比较各胶种热学性能的差异,并探究升温速率对热重曲线的影响;通过垂直、水平燃烧试验进行材料燃烧性能表征,并对材料的阻燃性进行分级。不同升温速率下丁腈橡胶和硅橡胶的失重温度最低,约210℃;氟橡胶的失重温度次之,约为390℃;而氟醚橡胶的失重温度最高,约为410℃。氟橡胶和氟醚橡胶的水平阻燃等级均为FH-1级。氟系列橡胶的水平阻燃性能优于其他胶种。The Thermogravimetric analysis was used to analyze the thermal stability of Nitrile rubber, Silicone rubber, Fluorine rubber and Fluorine ether rubber. The weight loss temperature and weight loss rule of four kinds of rubbers were studied at different heating rates, which can determine the thermal per formance of the rubber, also to study the effect of heating rate on the thermal weight curve. The material＇s combuslion per formance was characterized by the horizontal burning test and the vertical burning test, so the flame resistance of the material was classified. The NitrIle rubber and Silicone rubber haw： tow mass loss temperature about 210 ℃, the mass loss temperature of Fluorine rubber is about 390 ℃ and the Fluorine ether rubber has higher mass loss temperature about 410 ℃. The combustion behavior of Fluorine series rubber is much better than other kinds of rubbers since the horizontal flame retardant grade is FH-1.
