摘要:

采用六甲基二硅氮烷对石英复合陶瓷进行烷基化改性，研究了烷基化改性前后材料的力学性能、吸潮性能、介电性能、氧乙炔烧蚀性能及粘接性能。结果显示，烷基化改性能够极大地改善石英复合陶瓷材料的防潮性能，对介电性能和氧乙炔线烧蚀率和粘接性能略有提升，对力学性能基本无影响。

Abstract:

Quartz composite ceramic material is alkylated modified by using HMDS. Mechanical properties, humidity resistance, dielectric properties, oxyacetylene ablation properties and adhesion properties of the materials are investigated. The results show that the alkylation modification can greatly improve humidity resistance of quartz composite ceramic material, slightly improve dielectric properties, oxyacetylene ablation properties and adhesion properties of the materials, and has no effect on mechanical properties of the materials.

Key words: alkylation modification quartz composite ceramic material property
