摘要/Abstract

摘要： 以牌号为F-613的非酸固化型拉挤酚醛树脂为研究对象,通过FTIR、GPC、流变仪、DSC等表征方法分析了该树脂的结构、分子量、粘度特性、固化特性、凝胶时间等。结果表明,该树脂的DSC曲线显示具有单一的固化峰,且固化峰温度较低,此外,高温下的凝胶时间较短,固化度较高,能够很好地满足低粘度、高活性、快速固化等拉挤工艺要求,并且工艺配方与成型工艺简单,由其所制备的复合材料与9450酚醛树脂的复合材料性能基本相当。

关键词: 酚醛树脂, 拉挤成型工艺, 复合材料

Abstract: A novel non-acid phenolic resin named F-613 for pultrusion process was studied. The structure, molecular weight, viscosity, curing properties and gelling time of this resin were characterized by FTIR, GPC, rheometer, DSC and etc. The DSC curve of F-613 phenolic resin displayed a single exothermic peak existing lower temperature area contrast to 9450 phenolic resin with two exothermic peaks in higher temperature area. Moreover, F-613 phenolic resin retains shorter gel-time at high temperature. The analysis results indicated that F-613, with shorter gel-time and lower exothermic peak temperature, is more applicable to pultrusion process because of its low viscosity, high activity and rapid solidification. Compared with that of 9450 phenolic resin, the formula and pultrusion process of F-613 were simpler under the condition of the same properties. The mechanical properties of glass fibre-reinforced composites shows no significant differences. But, the distinct properties of F-613 phenolic resin systems is no corrosion to mould during the pultrusion process.

Key words: phenolic resin, pultrusion process, composites
