摘要
以白炭黑 (超细 Si O2 )、B4C对酚醛树脂 (Phenol-Formaldehyde Resin,PF)改性后制备的高温粘结剂具有较好的粘接效果。本文借助于红外光谱 (IR)对不同温度热处理后的粘接样品进行结构分析 ,以考察热解过程中的结构变化特点及其与性能间的相关性。
In the present paper, pyrolysis process of phenol\|formaldehyde resin mixed with white carbon black(nano\|silica) and boron carbide powders was investigated. The material was used as a high temperature adhesive for graphite bonding. Based on the IR analysis results of the adhesives heat\|treated at different temperatures, the relationship between change of the composition and structure of the adhesives and the adhesive strength were discussed.
