The invention discloses a high-temperature 160 DEG C resistant rubber, the rubber comprises the following components: butyronitrile rubber, zinc oxide, stearic acid, carbon black N330, carbon black N660, paraffin oil, paraffin wax, sulfur, 2-deoxy-2,2difluoro-pentafuranosyl-1-keto-3,5-dibenzoate, 1-(2-dimethyl aminoethyl)-1H-5-sulfydryl-tetrazole, 2-chloromethyl-3-methyl-4-(2,2,2-trifluoroethoxy)pyridinehydrochloride, an antioxidant and an accelerator. Compared with the prior art, by adding 2-deoxy-2,2difluoro-pentafuranosyl-1-keto-3,5-dibenzoate, 1-(2-dimethyl aminoethyl)-1H-5-sulfydryl-tetrazole and 4,5,6,7-thiophane[3,2-C]pyridinehydrochloride, the heat resistant temperature of the butyronitrile rubber can be increased to 160-170 DEG C.
Description
technical field [0001] The invention relates to rubber, in particular to 160-degree-resistant high-temperature rubber used for pipe liners. Background technique [0002] Nitrile rubber has good water resistance and oil resistance, and is often used as a bushing for pipelines, but its temperature range is -40 to 120 °C, and it is not suitable for the transportation of liquids above 160 °C. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-temperature-resistant rubber suitable for liquid transportation at a temperature of 160°C. [0004] The technical scheme for solving technical problems of the present invention is: high-temperature rubber resistant to 160 degrees, containing the following substances and parts by weight: [0005] [0006] [0007] The model of described nitrile rubber is 3365E. [0008] The anti-aging agent is: 2,2,4-trimethyl-1,2-dihydroquinoline polymer, anti-aging agent RD. [000...
