Abstract

The invention discloses an anticorrosive cable sheath material for an oil well. The anticorrosive cable sheath material comprises the following raw materials in parts by weight: 20 to 25 parts of natural rubber, 13 to 20 parts of chlorosulfonated polyethylene, 15 to 20 parts of chlorinated polyethylene, 20 to 30 parts of modified polyphenylene oxide resin, 0.8 to 1.3 parts of tert-butyl peroxybenzoate, 2 to 3.5 parts of DCP (dicumyl peroxide), 1.5 to 2 parts of DBP (dibutyl phthalate), 15 to 21 parts of lead oxide, 1.5 to 3 parts of HVA-2, 15 to 20 parts of channel black, 30 to 40 parts of quartz powder, 2 to 4 parts of aluminum hydroxide, 1.5 to 3 parts of magnesium hydroxide, 4 to 7 parts of light magnesium oxide, 1 to 4 parts of triethanolamine, 20 to 24 parts of calcined clay, 0.5 to 1.5 parts of anti-aging agent ODA, 1 to 2.5 parts of anti-aging agent 4010NA and 0.3 to 1.2 parts of accelerator TMTD. The anticorrosive cable sheath material for the oil well is high in anticorrosive performance and flame retardant property, low in toxicity and long in service life.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials for oil wells, in particular to an anti-corrosion cable sheath material for oil wells. Background technique [0002] Since most of the cables for oil wells are used in the harsh environment underground, most of them are high-temperature, flammable, and highly corrosive underground. After several years of rapid development, my country's mine cables have formed a considerable scale, and the production capacity has greatly exceeded this year's forecast demand. At the same time, wire and cable companies are facing the problem of urgently improving the technical content of their products. How to prepare an anti-corrosion, flame-retardant, and low-toxicity mine cable has become a technical problem that needs to be solved at present. Contents of the invention [0003] The invention provides a cable sheath material for anti-corrosion oil wells, which has excellent anti-corrosion performanc...
