Morphology Evolution and Mechanical Properties of HNBR Composites Reinforced by HZMMA/Carbon Black during Curing Process

Abstract:

Hydroxyl zinc mono-methacrylate/carbon black/hydrogenated nitrile rubber composites were prepared by using HZMMA as a partial substitution for carbon black. The morphology and properties of the composites during the vulcanization process were investigated. The results showed that during early stage of the curing process, the tensile strength and modulus at 100% of the composites increased slightly, the tear strength and elongation at break decreased. The favorable mechanical properties for composites could be achieved after post-curing. FTIR, XRD, and TEM results showed that the polymerization of HZMMA completes at the beginning stage of curing process. Grafting and crosslinking reaction between HZMMA and HNBR may occur during the curing process and metallic bridge bond between them forms. The phase state of homopolymer transformed from disperse phase to continuous phase and has a good compatibility with HNBR.
