Abstract

The invention discloses oil-proof abrasion- resisting rubber which is made of materials comprising end carboxyl liquid butadiene-acrylonitrile rubber, butyronitrile 1041, octylphenolic resin, zinc oxide, stearic acid, N-cyclohexyl-N'-phenyl-p-phenylenediamine, 2,2,4-trimethyl-1,2-dihydroquinoline, carbon black N660, dibutyl phthalate, N-cyclohexylbenzothiazole-2-sulphenamide, dibenzothiazyl disulfide, tetramethyl thiuram disulfide and sulphur. Compared with the prior art, the oil-proof abrasion-resistance rubber has the advantages that volume swelling of the rubber is less than 50% after the rubber is in a 40DEG C solution for 48 hours, oil-proof abrasion-resisting performance is good, and the oil-proof abrasion-resisting rubber is applicable to an inside liner of a marine oil suction hose.

Description

technical field [0001] The invention relates to a rubber, in particular to an oil-resistant and wear-resistant rubber used for the inner lining of marine oil-absorbing hoses. Background technique [0002] The inner liner of the marine oil suction hose is the working surface for transporting crude oil or liquid petroleum products. There are certain requirements for the oil resistance of the rubber used. It is required that the rubber should be placed in C liquid at 40°C for 40 hours, and the volume expansion rate should not exceed 60%. ; At the same time, it needs to be wear-resistant. At present, the oil resistance and wear resistance of traditional ordinary rubber cannot meet this requirement, so it cannot be used in the manufacture of the inner lining layer of marine oil suction hose. Contents of the invention [0003] In order to overcome the above problems, the object of the present invention is to provide an oil-resistant and wear-resistant rubber. Th...
