摘　　要：本文将醚胺类改性剂加入2,4-二氨基二苯甲烷(DDM)中得到液态低粘度固化剂混合物。测试了混合固化剂/E-54体系的凝胶时间、与玻璃纤维的浸润性及浇注体和复合材料的性能。结果表明,此体系具有小于1 000 mPa.s的粘度和5h左右适用期,固化物拉伸强度为85.78 MPa,断裂延伸率为4.26%,热变形温度为109℃。The mixture curing agent with low viscosity was obtained by mixing DDM with modified agent. The testing of gel time, capillary impregnation and mechanical measurement showed that E54/mixture curing agent system has a viscosity of 1 000 mPa.s,the gel time of 5h and tensile strength is 85.78 MPa with a elongation at break of 4.26% ,and HDT is 109℃.
