摘要HNBR具有优异的耐油性、耐化学药品性、耐热、耐高温高压和耐臭氧等性能，因而在工业领域中具有广泛的应用。但HNBR与金属粘接性能较差，在一定程度上限制了其发展。本文在HNBR中混入少量的HXNBR，采用DCP和硫磺的双硫化体系对HNBR/HXNBR共混胶进行硫化，并利用正交试验设计方法，优化出了HNBR/HXNBR的最佳硫化体系，得到硫化胶的最佳硫化配方为：DCP2份、TAIC1.5份、S0.5份和TMTD2份，该配方下的HNBR/HXNBR共混胶具有最优异的综合性能。最优配方下的共混胶性能为：拉伸强度29.52MPa，断裂伸长率409%，撕裂强度65.43KN•m-1，磨耗体积0.08008cm3。63626

Title  Study on Compounding Systems on HNBR/HXNBR Blends                           

Abstract

Due to its excellent properties such as oil resistance, chemical resistance, heat resistance, resistance to high temperature and high pressure, and resistance to ozone, HNBR is widely used in many industrial fields. However，HNBR has poor adhensive to metal which limits its development.In this paper, HNBR was mixed with a little of HXNBR and the rubber blends were cured with DCP and sulfur curing system. Then, the optimum curing systems of HNBR/HXNBR blends was gained by using orthogonal design. The results shows that, the optimum curing system was as follows: DCP 2phr、TAIC 1.5phr、S 0.5phr and TMTD2phr.

The HNBR/HXNBR blends cured by the optimum curing system has the excellent performance. The tensile strength of rubber blends was 29.52MPa, the elongation at break was 409%, the tear strength was 65.43KN/m-1, and the abrasion volume was 0.08008/cm3.
