摘要(Abstract)：

制备了3种密封膜片，并对其进行性能研究。结果发现：高温处理后，密封膜片Ⅰ和密封膜片Ⅱ中的密封胶在基布的纤维之间均有分布；密封膜片Ⅰ和密封膜片Ⅱ在250～350℃热处理后，其密封胶的形态保持良好；3种密封胶都能在一定程度上改善基布的韧性，所制密封膜片的断裂伸长率大于玄武岩基布的；经250～350℃高温处理后，3种密封膜片的断裂强力保持率均在65%以上。对密封膜片进行同步热分析发现：热分解起始阶段密封膜片的温差排序为密封膜片Ⅱ<密封膜片Ⅲ<密封膜片Ⅰ；热分解进行阶段膜片所产生的质量损失率排序为密封膜片Ⅱ<密封膜片Ⅰ<密封膜片Ⅲ；分解末尾阶段膜片的质量保持率排序为密封膜片Ⅱ>密封膜片Ⅰ>密封膜片Ⅲ。
Three kinds of sealing diaphragm were prepared and their properties were studied. The results show that after high temperature treatment, the sealant in sealing diaphragm Ⅰ and sealing diaphragm Ⅱ is distributed between the fibers of the base cloth. After heat treatment at 250～350 ℃, the shape of the sealant of sealing diaphragm Ⅰ and sealing diaphragm Ⅱ remains good. The three sealants can improve the toughness of the base cloth to a certain extent, and the elongation at break of the sealing diaphragm is greater than that of the basalt base cloth. After high temperature treatment at 250～350 ℃, the breaking strength retention rate of the three sealing diaphragms remains above 65%. Through the synchronous thermal analysis of the sealing diaphragm, it is found that the sequence of the temperature difference of the sealing diaphragm in the initial stage of thermal decomposition is: sealing diaphragm Ⅱ < sealing diaphragm Ⅲ < sealing diaphragm Ⅰ, the sequence of the mass loss rate caused by the diaphragm in the stage of thermal decomposition is: sealing diaphragm Ⅱ < sealing diaphragm Ⅰ < sealing diaphragm Ⅲ, and the sequence of the mass retention rate of the diaphragm at the end of decomposition is: sealing diaphragm Ⅱ > sealing diaphragm Ⅰ > sealing diaphragm Ⅲ.
