Terephthalic acid,diethylenetriamine,triethylenetetramine were used as materials to prepare Polyamide through melt polycondensation in this paper. Their structures were studied with FTIR, and the effect of reaction temperature, reaction time, the ratio of raw material on the product performance have been discussed and the best routing of epoxy resin curing agent was also studied. finally, the synthesis of polyamide curing agent with diamino diphenyl sulfone were prepared composite curing agent. The results indicated that when the molal weight ratio of adipicacid terephthalic acid to was 1:2.0,amidation reaction lasted for 2 hours under 180℃, and the curing agent Composite curing agent of the best mixed mass ratio was1:5, the best mixed mass ratio of the Composite curing agent to epoxy resin was 1:10,the fast curing epoxy cover-layer was cured in150~170℃/10 min, the PS was 1.38N/mm,The preparation of epoxy fast curing cover-layer curing speed, good comprehensive performance, can meet the production requirements of FCCL.
