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.
