%X 研究粉状填料（以下简称填料）含水率对氟橡胶硫化特性、物理性能、耐热空气老化性能和耐介质性能的影响。结果表明：以氟化钙为主的填料（氟化钙＋活性氧化镁＋氢氧化钙）经历不同温湿度环境时会发生显著的吸潮现象；随着填料含水率的增大，氟橡胶的硫化速率增大；填料吸潮会引起老化前以及老化后氟橡胶的拉断伸长率波动；填料含水率增大会造成200 ℃×24 h热空气老化后和150 ℃×24 h航空煤油RP-3浸泡后氟橡胶的压缩永久变形增大；填料含水率对航空煤油RP-3浸泡前后氟橡胶的质量变化率和体积变化率没有显著影响。;The effects of the moisture content of powder filler（hereinafter referred as filler） on vulcanization charecteristics，physical properties，hot air aging resistance and oil-resistant properties of fluororubber were studied.The results showed that the calcium fluoride-based filler（calcium fluoride＋active magnesium oxide＋calcium hydroxide） had significant moisture absorption when it experienced different temperature and humidity.The vulcanization rate of fluororubber increased with the increase of water content of filler.The moisture absorption of filler would cause the fluctuation of the tensile elongation of fluororubbers before and after aging.The increase of moisture content of filler would cause the compression set increase after aging in hot air on 200 ℃×24 h and soaking in aviation kerosene RP-3 fuel on 150 ℃×24 h.The moisture content of filler had less significant effect on the mass and volume change rate of fluororubber before and after soaking in aviation kerosene RP-3 fuel
