摘要

摘要: 研究了含环氧基团丙烯酸酯液体橡胶对环氧树脂三乙醇胺固化体系的增韧作用。结果表明,增韧环氧树脂体系是以橡胶粒子为分散相的两相结构,丙烯酸酯液体橡胶能显著地提高环氧树脂的冲击强度和断裂韧性GIC,幅度分别达63.0%和350%,而拉伸性能、弯曲性能和玻璃化温度的降低幅度不大。

Abstract: Toughening of epoxy resin by modification with acrylate liquid rubber containing pendant epoxy groups was investigated. The additions of 5phr of liquid rubber lead to 63% and 350% increase in impact strength and fracture toughness GIC) respectively. At the mean time, tensile strength, tensile modulus, flexural strength and glass transition temperatures of modified resin were less than that of the parent epoxy resin. The SEM analysis of the fracture surfaces indicated that the modified epoxy system exhibited two-phase morphology with rubber sphericity particles dispersing in matrixes.
