Description

technical field [0001] The invention relates to a high-performance hydrogenated nitrile-butadiene rubber compound and a preparation method thereof. Background technique [0002] Hydrogenated nitrile rubber is a high-performance elastomer whose main chain is nearly saturated. It has excellent comprehensive properties and is widely used in oil field development, automobiles, machinery supporting industries and other industries. In recent years, with the rapid development of my country's petroleum, automobile, aviation and other industries, the working environment of various industrial equipment has become more and more harsh, such as high temperature, high pressure, long cycle and different environmental media, etc. The performance of hydrogenated nitrile rubber products puts forward higher requirements, especially its high temperature resistance, oil resistance and mechanical properties. [0003] Existing hydrogenated nitrile rubber compounds can only perform better on a cert...
