Abstract

The invention discloses a diesel oil-resisting low pressure change nitrile rubber material and a preparation method thereof and belongs to the technical field of rubber. The rubber material is prepared from the following components: 100 parts of raw nitrile rubber, 5 parts of zinc oxide, 1 part of stearic acid, 70 to 105 parts of carbon black, 0 to 10 parts of a softened plasticizer TP-95, 2 partsof an antiager RD, 1 part of an antiager ZMMBI, 1 to 2 parts of a flow dispersant WB222, 9 to 12 parts of a vulcanizing agent Perkadox 14-40B-GR and 4.5 to 6 parts of a crosslinking agent Ricon153D.According to the preparation method disclosed by the invention, by reasonably matching the components of the raw nitrile rubber, nitrile rubber with high-content acrylonitrile is combined with the rawnitrile rubber filled with liquid nitrile and containing middle-content acrylonitrile; and the prepared nitrile rubber material has the characteristics of excellent diesel oil resistance, low compaction set and low temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of rubber, and more specifically relates to a nitrile rubber material with excellent resistance to diesel oil, low pressure change and low temperature resistance and a preparation method thereof. Background technique [0002] With the continuous development and innovation of automobile manufacturing technology and the increasing awareness of energy conservation and environmental protection, automobile filters are also constantly being updated, and their performance requirements are getting higher and higher. The main function of the diesel filter is to filter out harmful impurities and moisture in the fuel system, protect the normal operation of the engine, reduce wear, avoid clogging, and improve engine life. The rubber diaphragm is one of the key components in the filter. The diesel aging resistance condition of the rubber diaphragm has been raised from the original 85°C×168h test standard to 85°C×1008h te...
