摘要/Abstract

摘要： 选用聚(间二乙炔基苯-甲基氢硅烷-苯基硅烷)树脂(PDMP)固化物,研究其在高温作用下的热解产物及其陶瓷化。借助X射线衍射(XRD)、能谱仪(EDS)和扫描电镜(SEM)等分析测试方法表征了高温热解产物的组成、结构和形貌。结果表明,热解产物表面出现许多凸起状的小球,且分布较为均匀,形成了陶瓷晶体。该陶瓷晶体的结构为Si-C,树脂固化物的陶瓷产率达80.83%。

Abstract: In this paper, the cured poly (m-diethynylbenzene-methylsilane-phenylsilane) resin (PDMP) was used to study cracking and ceramics under high temperature. The composition, structure and morphology of pyrolysis products were characterized by X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and scanning electron microscope (SEM). The results showed that many bulging balls were found on the surface of the pyrolysis products and distributed uniformly. It showed that ceramic of SiC structure crystals was formed, and the ceramic yield of the cured resin was 80.83%.

Key words: high temperature resistant, silicon aryne resin, pyrolysis, preceramic
