摘要

陶瓷化高分子材料具有优异的阻燃和防火性能，在国外已经有公司制备了这种材料来代替传统的防火材料。以硅橡胶为基体，通过添加玻璃粉，制备了一种陶瓷化高分子材料，研究了玻璃粉用量对硅橡胶力学性能和电学性能的影响，通过SEM观察了瓷化物表面和断面的形貌。结果显示，瓷化物表面比较致密，气孔较少，有一些玻璃相形成；断面存在大量气孔，具有较好的瓷化性能，瓷化物致密而又坚硬，可以抵抗至少1000℃的高温。随着玻璃粉添加量的提高，硅橡胶的流动性变差，硫化速率加快，拉伸强度和断裂伸长率都有不同程度的下降，邵氏硬度A一直上升，体积电阻率和表面电阻率则都呈现出先增大后减小的趋势。

Abstract

Ceramifying polymer materials have been developed to replace conventional fire protection materials for their excellent qualities. In this paper

ceramifying silicone rubber was prepared by blending silicone rubber and glass frits. The effects of glass frits on the mechanical and electrical properties were investigated. SEM was used to observe the surface and cross-section of ceramic residue after fired. The results showed that the prepared material has desirable ceramifying properties and the compact

hard ceramic residue could resist high temperature over 1000 ℃. As addition of glass frits increased

fluidity of silicone rubber became worse

tensile strength and elongation decreased to some extent

while shore A hardness increased

both volume and surface resistivity firstly increased and then decreased.
