尼龙树脂丁腈橡胶共混型热塑性弹性体的研究

Study of Nylon/NBR Blended Thermoplastic Elastomer

本文研究了丁腈橡胶(NBR)与尼龙(Nylon)树脂共混改性技术,制备具有耐热油性的Nylon/NBR共混型热塑性弹性体。通过采用动态硫化方法、改变两种高分子材料的共混量以及选择各种硫化体系等,对热塑性弹性体的力学性能以及耐油性、耐热氧老化性能的影响,进行系统的研究。研究结果,制得具有优秀耐热油性和良好的综合力学性能的热塑性弹性体材料。此外,对共混型热塑性弹性体的亚微观相畴形态也进行了相差显微镜的观察。

Blended thermoplastic elastomer from Nylon/Nitrile rubber has been prepared by modification and blending techn ique.The dependence of variation of blend ratio, selected curing systems and dynamic vulcanization method on the physical properties, oil resistance, thermal aging and oxidation resistance have been systematically studied.The blends made by this technique possess an excellent oil res istance and a combination of mechanical properties. The morphology and submicro phase domain size of the blend have been also observed by phase contrast microscopy.
