Abstract

The invention provides a heat-resistant and oil-resistant rubber hose. The heat-resistant and oil-resistant rubber hose comprises an outer rubber layer, an inner rubber layer and a framework layer located between the outer rubber layer and the inner rubber layer. The inner rubber layer is composed of, by mass, 100 parts of hydrogenated acrylonitrile butadiene rubber, 30-40 parts of semi-reinforcing carbon black, 20-30 parts of fast extruding furnace black, 15 parts of white carbon black, 5-10 parts of tricresyl phosphate, 0.5-1.5 parts of stearic acid, 1-3 parts of 2,2'-diurethane dimethacrylate-(4-methyl-6-tert-butylphenol), 1-2 parts of polyethylene glycol 4000, 4-6 parts of activated zinc oxide, 0.5-2 parts of accelerant DM, 0.8 part of vulcanizing agent dicumyl peroxide, 1 part of sulphur, 2-3 parts of assistant crosslinker triallylisocyanurate. The heat-resistant and oil-resistant rubber hose further comprises a middle rubber layer. The middle rubber layer is composed of, by mass, 90-110 parts of rubber, 0.5-1.5 parts of active agent, 10-12 parts of vulcanizing agent, 1-2 parts of accelerant, 32-48 parts of reinforcing agent, 16-24 parts of plasticizer, 2-3 parts of anti-aging agent and 20-30 parts of binding agent. By the adoption of the optimum rubber material formula, the heat-resistant and oil-resistant rubber hose has the excellent advantage of being resistant to high temperature, oil, pressure and deflection.

Description

technical field [0001] The invention belongs to rubber products, in particular to a rubber hose, in particular to a heat-resistant and oil-resistant rubber hose. Background technique [0002] The hose structure is usually divided into: inner rubber layer, outer rubber layer and skeleton layer (or middle layer). The inner rubber layer directly bears the wear and erosion of the conveying medium, the outer rubber layer protects the inner body of the rubber hose from damage and erosion of the external environment, and the skeleton layer is the pressure-bearing layer of the rubber hose, giving the hose body strength and rigidity. Rubber hoses have been used in many fields of life and production. Common pipes include: water pipes, hot water pipes, steam pipes, marine pipes, food and beverage pipes, air pipes, welding pipes, gas pipes, ventilation pipes, material pipes, oil pipes, Chemical tubes, high pressure tubes, etc. [0003] With the rapid development of my country's indust...
