| 摘要: |
| 为降低有机硅树脂固化的温度和时间,利用环氧树脂对自制有机硅低聚物进行改性,并进一步在改性硅树脂中添加铝粉、高岭土及白炭黑等功能填料制备复合有硅树脂溶液,将其涂覆在玻璃纤维织物表面,最终制备出具有低温固化功能的隔热涂层玻璃纤维织物.结果表明:环氧树脂分子侧链上的仲羟基与有机硅低聚物发生了接枝反应,环氧基团的保留也为涂层过程中实现低温固化提供了条件；改性硅树脂在700 ℃时的残留质量为66.2 %,具有良好的热稳定性；复合有机硅树脂涂层后的织物可在60 ℃下烘10 min,完成固化过程,烧蚀试验表明涂层后织物的隔热性能显著提高. |

| Abstract: |
| In order to decrease the curing temperature and time of organic silicone, epoxy resin was grafted on the silicone resin. The inorganic fillers, such as aluminium, kaoline and white carbon powder, were added into the grafted silicone resin and then coated onto glass fiber fabric. Infrared spectroscopy indicated the sec-hydroxyl groups on the branched chain of the epoxy resin reacted with silicone. 66.2 wt% residual mass at 700 ℃ was obtained by TGA (Thermo Gravimetric Analyzer), which indicated that the grafted silicone was stable at high temperature. The coating fabric was cured at 60 ℃ for 10 min to finish the curing process. The ablation test showed that the heat insulating property of the coating fabric was much higher than that of the original fabric. |
