Wear-resistant and oil-resistant rubber material for inner sheath of mining power cable and preparation method for rubber material

Abstract

The present invention discloses a wear-resistant and oil-resistant rubber material for an inner sheath of a mining power cable and a preparation method for the rubber material. The wear-resistant and oil-resistant rubber material is prepared from the following raw materials in parts by weight: 26-34 parts of fluorosilicone rubber, 15-25 parts of chloroprene rubber, 13-19 parts of high-cis polybutadiene rubber, 7-13 parts of di-iso-octyl sebacate, 4-6 parts of shellac cera, 3-5 parts of sulfur dichloride, 5-8 parts of poly alpha olefin, 2-3 parts of zinc oxide, 3-4 parts of stearic acid, 2-3 parts of an antioxidant ODA, 1-2 parts of an antioxidant AW-66, 15-20 parts of highly wear-resistant carbon black, 10-15 parts of nano-diamond, 3-5 parts of di-t-butyl peroxide, 1-2 parts of an accelerant ETU, 1-2 parts of an accelerant TMTD, 0.5-1 part of an accelerant ZDC, 10-15 parts of electrolytic aluminum slag and 16-22 parts of flame retardant particles. According to the material prepared by the present invention, the oil resistance and wear resistance are greatly improved, and meanwhile the mechanical property is not influenced.

Description

technical field [0001] The invention relates to a wear-resistant and oil-resistant rubber material for the inner sheath of a mining 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 inner sheath materials for power cords in the market. However, with the rapid development of science and technology, the wear resistance and o...
