Abstract

The invention discloses a hose lining material for an ultrahigh-pressure wire-wound hydraulic hose and a preparation method of the hose lining material. The hose lining material is prepared from raw materials in parts by weight as follows: 50-70 parts of nitrile butadiene rubber, 30-50 parts of a rubber and plastic alloy, 6-7 parts of an active agent, 3 parts of an anti-aging agent, 6 parts of a plasticizer, 80-85 parts of carbon black 774 and 3.5-3.7 parts of a vulcanization accelerator, and the material is prepared through primary smelting, mixing, extrusion and vulcanization procedures. The problems of failure in high temperature resistance, forming of pinholes and oil leakage of high-pressure wire-wound hydraulic hoses are solved, and the use requirements of high-pressure and high-pulse wire-wound hydraulic hoses are met.
