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.
