摘要:
本文选用硫磺硫化体系,用动态硫化法制备PVC/NBR共混型热性弹性体(TPE),该材料具有强度高、永久变形小和可重复加工等特点。考查了共混时间、交联剂含量等因素对材料力学性能及共混比对流变性能的影响。通过透射电子显微镜观察,PVC/NBR共混物呈现出明显的两相结构。交联的NBR为分散相,分散于PVC连续相中。动态硫化PVC/NBR共混型热塑性弹性体在压缩永久形变、扯断永久变形、耐油及耐老化等主要性能上均优于简单机械共混物。
Abstract:
This article uses a sulfur vulcanization system to prepare the PVC / NBR mixed thermal elastomer (TPE) with dynamic vulcanization method. This material has the characteristics of high strength, permanent deformation, and repeated processing. The effects of factors such as co -mixing time, cross -linked content and other factors have on the mechanical properties of materials and the performance of common comparative comparison flow. Through the observation of electron microscope, the PVC / NBR co -mixture presents a clear two structures. The cross -linking NBR is decentralized and scattered in the PVC continuous phase. Dynamic vulcanization PVC / NBR co -mixed thermoplastic elastic body is better than simple mechanical co -mixture in compressed permanent transformation, interrupt permanent deformation, oil resistance and aging resistance.
