摘　　要：采用HDPE对杜仲胶进行共混改性,通过测定硫化胶的形状记忆性能、物理机械性能(断裂伸长率、拉伸强度、弯曲强度)确定出体系的较佳配方。结果表明:体系中HDPE、硫黄、白炭黑和KH-560的较佳用量(质量份)分别为15%、1%、20%和2%;加入KH-560后,材料的记忆性和力学性能增强。The gutta-percha was modified by HDPE through blending method. The Effects of HDPE, sulfur, white carbon black and KH-560 content on shape memory property and mechanical properties such as breaking elongation, tensile strength and bending strength of the rubber were studied. The results showed that the better content of HDPE, sulfur, white carbon black and KH-560 were 15 %, 1%, 20% and 2 %, respectively. The shape memory property and mechanical properties were both enhanced when KH-560 was introduced in the system.
