The invention discloses an oil and wear resistant rubber which contains the following substances: natural rubber, tread rubber, zinc oxide, stearic acid, carbon black N330, paraffin, coumarone, sulfur, asphalt, methyl-2,2-dithienylglycolate, dimethyl 4-nitrophthalate, 3-[(3-amino-4-methylaminobenzoyl)pyridine-2-yl-amino]ethyl propionate, an antioxidant and a promoter. Compared with the prior art, the invention has the following advantage: through addition of methyl-2,2-dithienylglycolate, dimethyl 4-nitrophthalate and 3-[(3-amino-4-methylaminobenzoyl)pyridine-2-yl-amino]ethyl propionate in a formula, oil resistance of natural rubber is increased to 5 to 6%.
Description
technical field [0001] The present invention relates to rubber, in particular to oil-resistant and wear-resistant rubber for pipe liners. Background technique [0002] In pipeline transportation in oil fields, the transported medium is a mixture of oil and ore, so the rubber used for the pipeline bushing is usually natural rubber containing tread rubber. Although the above rubber has wear resistance, its oil resistance is very poor. , its oil resistance can only reach more than 15%. Contents of the invention [0003] The technical problem to be solved by the invention is to provide an oil-resistant and wear-resistant rubber with an oil resistance of 5-6%. [0004] The technical scheme for solving the technical problems of the present invention is: an oil-resistant and wear-resistant rubber, which contains the following substances and parts by weight: [0005] [0006] [0007] The anti-aging agent is: 2,2,4-trimethyl-1,2-dihydroquinoline polymer, anti-aging agent R...
