摘要/Abstract

摘要： 设计了一种新型磷-硅协同高效无卤阻燃环氧树脂610B,并制备了碳纤维增强热熔预浸料T700/610B。通过DSC、凝胶时间、动态黏度、热重、红外和SEM,对树脂体系的反应及流变特性、室温储存期和阻燃机理进行研究;通过真空袋成型工艺制备了碳纤维增强复合材料并对其力学性能和阻燃性能进行了评价。结果表明:树脂在中温条件下有效固化,室温下储存期大于30 d,预浸料铺覆性好,适合低成本真空压力成型,制备的复合材料力学性能优异、低烟低毒、阻燃性能突出。

Abstract: A new kind of phospho-silicon synergistic halogen-free flame-retardant epoxy resin 610B was designed, and the hot-melt prepreg T700/610B was prepared. DSC, gel time, dynamic viscosity, TGA, IR and SEM were used to study the reaction and rheological characteristics of the resin system, the storage period at room temperature and the mechanism of the flame retardant. Carbon fiber reinforced composites were prepared through vacuum bag only forming process, and mechanical properties and flame-retardant properties were evaluated. The results show that the resin can be cured under medium temperature condition, and its storage life at room temperature is more than 30 days. The prepreg shows good processability, and suitable for the low-cost vacuum bag only molding. The composite shows outstanding flame-retardant performance of low smoke and low toxicity, as well as excellent mechanical performance.

Key words: halogen free flame retardant, epoxy resin, hot melt prepreg, low smoke and low toxicity, rail traffic
