Abstract

The invention discloses an oil-resistant rubber pipe. The oil-resistant rubber pipe comprises the raw materials in parts by weight: 40-60 parts of nitrile-butadiene rubber, 30-40 parts of silicone rubber, 3-8 parts of polyvinyl chloride, 7-14 parts of dicumyl peroxide, 1-5 parts of sulfur, 4-8 parts of bisthiuram tetrasulfide, 3-8 parts of benzoyl peroxide, 5-10 parts of zinc oxide, 1-5 parts of calcium hydroxide, 2-6 parts of light calcium carbonate, 3-10 parts of white carbon black, 1-3 parts of nano-graphite, 2-7 parts of modified nano talcum powder, 2-5 parts of nano zinc sulfide, 3-7 parts of dibutyl phthalate, 1-5 parts of plasticizer, 0.5-1.5 parts of anti-aging agent and 2-4 parts of accelerant. The oil-resistant rubber pipe disclosed by the invention has good oil resistance and meanwhile is high in mechanical strength and good in heat resistance, and thus, actual use requirements can be met.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an oil-resistant rubber tube and a manufacturing process thereof. Background technique [0002] The characteristics of the rubber tube are physiological inertia, UV resistance, ozone resistance, high and low temperature resistance (-80 to 300 degrees), high transparency, strong resilience, compression resistance, permanent deformation, oil resistance, stamping resistance, acid and alkali resistance, wear resistance, Flame retardant, voltage resistance, conductivity and other properties. Rubber hoses are widely used in the automotive industry. In the automotive industry, rubber hoses are especially required to have good oil resistance and a certain strength. The rubber hoses manufactured in this way can meet the actual use requirements. [0003] Therefore, how to develop a kind of rubber tube with excellent mechanical strength, heat resistance and oil resistance just seems very ne...
