摘　　要：在环氧树脂E44/端氨基聚醚D-2000体系中加入丙烯酸丁酯（BA）改性的二乙烯三胺（BA-DETA）及四乙烯五胺（BA-TEPA）固化剂,通过粘度和声学性能测试对比了加入DETA,BA-DETA及BA-TEPA的体系的粘度,固化物的表观特性及水声性能。结果表明：加入BA-DETA的E44/端氨基聚醚D-2000体系2~25 k Hz频率下透声系数均值为0.879,反射系数均值为0.069,尤其是在中低频（2-10 k Hz）时,其透声系数均在0.9以上,具有良好的透声性能。The butyl acrylate（BA） modified diethylenetriamine（BA-DETA） and tetraethylene pentamine（BA-TEPA） curing agent was added in the epoxy E44/amino-terminal polyether D-2000 system,respectively. The viscosities,apparent properties and underwater acoustic properties of the cured systems adding DETA,BA-DETA and BA-TEPA were compared by the viscosity and acoustic performance tests. The results showed that the mean value of sound transmission coefficient and the average reflection coefficient of E44/amino-terminal polyether D-2000 system with BA-DETA at the frequency of 2 ~ 25 k Hz were 0.879 and 0.069 respectively,especially at low to medium frequency（2-10 k Hz）,the sound coefficients was above 0.9,with good sound transmission performance.
