隔热耐烧蚀玻璃纤维织物的制备

为制备隔热耐烧蚀玻璃纤维织物，在苯甲基硅树脂溶液中添加无机填料制备复合有机硅树脂溶液，对玻璃纤维织物进行涂层。采用隔热性能测试、热重分析和烧蚀试验等手段研究了玻璃纤维织物的隔热和耐烧蚀性能。结果表明：在硅树脂溶液中，添加各类填料的较优质量分数为白炭黑10%左右、云母粉5%左右、硅灰石粉2-5%、三氧化二铬5%；按照正交试验最优处方制得的涂层玻璃纤维织物在1000℃火焰上烧蚀，织物背面温度达到200℃所需要的时间为8.4秒，明显高于普通玻璃纤维织物所需要的3.0s。

Preparation of glass fiber fabrics with properties of heat insulation and ablative resistance

In order to prepare glass fiber fabrics with properties of heat insulation and ablative resistance, inorganic fillers were added in the resin solution to fabricate the composite organic silicon resin. Then the composite organic resin was coated on glass fiber fabrics. Heat insulation and ablative resistance properties of glass fiber fabrics were characterized by the heat insulation test, TG analysis and ablative experiment. The results indicate that the optimum dosages of inorganic fillers were as follows: white carbon about 10%, mica powder about 5%, wollastonite powder 2-5%, and chromic oxide 5%. The ablative test showed that the back temperature of the coating glass fiber fabrics, which were fabricated according to the optimum processes of orthogonal test, reaching 200℃ took more than 8.4s, it was obviously higher than 3.0s of the original glass fiber fabric.
