The graphene-containing HNBR nanocomposite adopts a simple technology, is low in cost, facilitates industrial production, is widely adaptive and has better economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and relates to a graphene-containing hydrogenated nitrile rubber nanocomposite material and a preparation method. Background technique [0002] Hydrogenated nitrile rubber (HNBR) is a new type of rubber material developed in the 1980s on the basis of nitrile rubber (NBR). It is a new generation of rubber that is comparable to fluororubber. Because HNBR is highly saturated, it not only inherits the advantages of NBR oil resistance, but also has excellent heat resistance, high pressure resistance, water vapor resistance, acid gasoline and other corrosive media, especially ozone resistance. Aging performance, and its resistance to hydrogen sulfide is unmatched by other oil-resistant rubber. At the same time, HNBR molecules have a high degree of regularity, so they have excellent tensile strength and good wear resistance. The excellent performance of HNBR meets the higher requirements of n...
