摘要： 开发了一种应用于阀门执行机构的柔性防火罩系统材料，防火罩由防火外层、隔热层和耐磨内层构成。以玻纤布为基布，利用苯甲基有机硅树脂进行涂层，获得防火系统的外层材料。探究复合织物中隔热层纤维毡的纤维种类和厚度对其隔热性能的影响规律。结果表明：涂层织物在500 ℃温度下烧蚀30 min后结构性能完好，拒液防潮，耐紫外、酸碱，产烟毒性达到GB/T 20285中的AQ2级；以石英织物、高硅氧玻纤织物为基布制备的涂层织物可抵御丁烷火烧蚀10 min；采用高硅氧涂层织物作为防护外层，48 mm玻璃纤维毡、氧化铝纤维毡作为隔热层的复合材料在1 100 ℃温度下经丁烷火烧蚀30 min后，防护外层没有烧穿且复合材料背面的温度均低于一般阀门执行机构的失效温度80 ℃。

Abstract: A flexible fireproof cover system material for valve actuators was developed. The fireproof cover consists of a fire-resistant outer layer, a thermal insulation layer, and a wear-resistant inner layer. Using glass fiber cloth as the base fabric and coating it with benzyl methyl silicone resin, the outer layer material of the fireproof system was obtained. The influence of the fiber type and thickness of the thermal insulation layer fiber mat in the composite fabric on its thermal insulation performance was explored. The results show that after ablation at 500 °C for 30 minutes, the coated fabric maintains intact structural performance, exhibits liquid repellency and moisture resistance, is resistant to ultraviolet rays, acids, and alkalis, and its smoke toxicity meets the AQ2 level in GB/T 20285. Coated fabrics prepared with quartz fabric and high-silica glass fiber fabric as the base fabric can withstand ablation by butane fire for 10 minutes. When using high-silica coated fabric as the protective outer layer and 48 mm glass fiber mat or alumina fiber mat as the thermal insulation layer, the composite material remains unburned through after 30 minutes of butane fire ablation at 1 100 °C, and the temperature on the back of the composite material is lower than 80 °C，which is the failure temperature of general valve actuators.
