Problems solved by technology

At present, hydrogenated nitrile rubber can be used in products such as screw pump rubber stators in crude oil extraction. At present, the rubber materials used in oil fields are basically concentrated in ordinary nitrile materials, but because crude oil contains a variety of corrosive media, plus The mining environment is getting worse and worse, making it difficult for the previous products to meet the current mining requirements

Abstract

The invention relates to rubber and improved rubber production processes, in particular to a production process of a high-temperature-resistant HNBR (hydrogenated nitrile butadiene rubber) nanocomposite. According to the production process, hydrogenated nitrile butadiene rubber serves as matrix materials, nanosilicon dioxide and carbon nano tubes are jointly used as reinforcement materials, organic peroxides serve as crosslinkers, multifunctional groups of activated monomers serve as assistant crosslinkers, and an open mill and an internal mixer are used for processing the rubber composite, so that the problems of nanofiller dispersion and interface adhesion among rubber are solved. Compared with existing rubber in performance, the HNBR nanocomposite processed by the production process has excellent normal-temperature mechanical property, high high-temperature mechanical property retention rate and excellent ageing resistance.

Description

technical field [0001] The invention relates to rubber, especially the production process of improved rubber. Background technique [0002] Hydrogenated nitrile rubber (HNBR) is a new type of rubber produced for the purpose of improving the heat resistance and weather resistance of ordinary nitrile rubber (NBR). Hydrogenated nitrile rubber is produced by hydrogenating the double bonds on the main chain of NBR macromolecules. Compared with NBR, it has improved heat resistance, weather resistance and chemical stability on the basis of maintaining better oil resistance. At the same time, its physical and mechanical properties have also been greatly improved. At present, hydrogenated nitrile rubber can be used in products such as screw pump rubber stators in crude oil extraction. At present, the rubber materials used in oil fields are basically concentrated in ordinary nitrile materials, but because crude oil contains a variety of corrosive media, plus The mining environment i...
