Abstract

The present invention discloses a high-temperature-resistant and wear-resistant rubber material for an inner sheath of a drilling power cable and a preparation method for the rubber material. The high-temperature-resistant and wear-resistant rubber material is prepared by using the following raw materials: acrylate rubber, butadiene-vinylpyridine rubber, a thermoplastic polyurethane elastomer, trinonyl benzene-1,2,4-tricarboxylate, aramid pulp, methane black, pine tar, coal pitch, C5/C9 copolymerized petroleum resin, an accelerant MBTS, an accelerant ZBPD, tungsten disilicide, ash calcium powder, tellurium powder, lanolin, pitch-based carbon fiber, an antioxidant OD, an antioxidant NAPM, an antioxidant WSL, diisopropyl peroxydicarbonate, N,N'-meta-phenylene-bis-maleimide and flame retardant particles. The material prepared by the present invention is not only excellent in mechanical property, but also is excellent in abrasive resistance and high-temperature resistance, and fully meets the using requirements of the inner sheath material of the drilling power cable.

Description

technical field [0001] The invention relates to a high-temperature-resistant and wear-resistant rubber material for an inner sheath of a drilling power cord and a preparation method thereof, belonging to the technical field of polymer material processing. Background technique [0002] The power cord is a wire that transmits current, which is mainly composed of an outer sheath, an inner sheath, and a conductor. The inner sheath is a layer of polymer material that wraps the cable between the shielding layer and the core. It is generally polyvinyl chloride plastic or polyethylene plastic, and there are also low-smoke and halogen-free materials. Its function is to prevent the insulating layer from contacting water. , air or other objects in contact, to avoid moisture insulation and insulation from mechanical damage. At present, there are many kinds of materials for inner sheaths of power cables on the market. However, with the rapid development of science and technology, the hi...
