摘　　要：为了研究光固化过程中多官能度丙烯酸酯磷酸酯促进剂(KM2160)对碳化硅/环氧树脂复合材料(SiC/EP)性能的影响,实验着重对不同促进剂含量的SiC/EP材料的固化速度、硬度、附着力进行讨论。通过红外光谱(FTIR)、邵氏硬度测试、压滤纸法等检测方法进行了测试与表征。结果表明,SiC/EP复合材料中加入一定比例的多官能度丙烯酸酯磷酸酯促进剂能够有效优化光固化加工性能。当多官能度丙烯酸酯磷酸酯促进剂质量分数为3%时,SiC/EP的硬度最高达到98.6 HD;促进剂质量分数为4%~5%表干时间最短达到11 s;促进剂质量分数为3%~4%附着力等级达到1级。In order to study the effect of multifunctional acrylate phosphate accelerator(KM2160)on the properties of silicon carbide/epoxy resin composite(SiC/EP)in the process of ultraviolet(UV)curing, the curing speed, hardness and adhesion of SiC/EP with different contents of accelerator were discussed.It was tested and characterized by Fourier transform infrared spectroscopy(FTIR),shore hardness test, filter press paper method and so on.The results show that the UV curing processability of SiC/EP composites could be effectively optimized by adding a certain proportion of multifunctional acrylate phosphate accelerator.When the content of multifunctional acrylate phosphate accelerator is 3%,the highest hardness of SiC/EP is 98.6 HD.The shortest surface drying time is 11 s when the content of accelerator is 4%~5%.The adhesion reaches grade 1 when the content of accelerator is 3%~4%.
