Abstract

Specialty engineering rubber has been put forward with more stringent requirements. In this paper, the material properties and reinforcing effects of several fillers were investigated, and polyamide was selected as the target reinforcing material to modify hydrogenated nitrile butadiene rubber (HNBR) in order to improve the temperature resistance of the system. It was concluded that the mechanical properties of PA1212/HNBR system were better than those of PC/HNBR system at 120°C. The optimum PA1212 additive amount was determined through the mechanical property test and dispersion state observation of the blended system, which proved that the PA1212 reinforcing system significantly improved the heat resistance and mechanical properties of HNBR. The modified HNBR has excellent tensile strength and elasticity, which effectively improves the reliability and service life of the sealing equipment under high temperature conditions, and provides experimental references and theoretical basis for the research and development of high-temperature resistant rubber.

氢化丁腈橡胶(HNBR) /聚酰胺1212 （PA1212）共混改性耐高温橡胶的研究

特种工程橡胶提出了更严格的要求。本文研究了几种填料的材料性能和补强效果，选择聚酰胺作为目标补强材料对氢化丁腈橡胶（HNBR）进行改性，以提高体系的耐温性能。结果表明，在120℃时，PA1212/HNBR体系的力学性能优于PC/HNBR体系。通过力学性能测试和共混体系的分散状态观察，确定了PA1212的最佳添加量，证明PA1212增强体系显著提高了HNBR的耐热性和力学性能。改性HNBR具有优异的抗拉强度和弹性，有效提高了密封设备在高温条件下的可靠性和使用寿命，为耐高温橡胶的研发提供了实验参考和理论依据。
