摘要
对环氧化天然橡胶ＥＮＲ－５０与聚丙烯共混制备热塑性弹性体进行了研究。试验结果表明，选用硫黄给予体硫化体系、采用“母炼胶”二段混炼工艺，加入适量的相容剂及白炭黑，可制得力学性能较好（拉伸强度１５ＭＰａ、扯断伸长率５００％、撕裂强度８３ｋＮ·ｍ－１）、中等耐油的热塑性弹性体。透射电镜观察表明，加入相容剂及白炭黑能有效地改善共混物的界面状况，从而提高共混物的力学性能。
A study was made on the TPE prepared with ENR-50/polypropylene blend.The test results showed that a TPE with good physical properties (tensile strength 15MPa,elongation at break 500%, tear strength 84kN. m-1 ) and moderate oil resistance could be made using two stage mixing process,sulfur donor system,and adequate compatibilizer and silica. It was observed with TEM that the boundary condition could be improved effectively with the addition of compatibilizer and silica, thus the physical properties of the blend improved.
