Abstract

The invention discloses an automobile fuel rubber pipe outer rubber and a preparation method thereof, and relates to the rubber product technical field; the automobile fuel rubber pipe outer rubber is mainly prepared from natural latex, butadiene rubber, a garlic essential oil, stearic acid, an anti-aging agent RD, a coupling agent Si69, bisphenol A unsaturated polyester resin, diisooctyl succinate sodium sulfonate, zinc oxide, titanium carbide, waste molding sand, laterite, dioctyl phthalate, a silicon boride micro-powder, epoxidized soybean oil, a modified additive and the like. The automobile fuel rubber pipe outer rubber has good reinforcing performance; a prepared rubber pipe has the advantages of high strength, good resistance to impact toughness, difficult bubbling and deformation, good high-temperature resistance, good aging resistance, good fuel oil resistance and low fuel oil permeability; and with use of the modified additive, the rubber pipe performance is improved overall, and the service life of the rubber pipe is improved.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to an outer rubber of an automobile fuel hose and a preparation method thereof. Background technique [0002] Hose is a type of tubular rubber product used to transport gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layers and a skeleton layer. The material of the skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. Generally, the inner and outer rubber layers of rubber hoses are made of natural rubber, styrene-butadiene rubber or butadiene rubber; oil-resistant hoses are made of neoprene and nitrile rubber; acid-resistant and high-temperature resistant hoses are made of ethylene-propylene rubber, fluorine rubber or silicone rubber. The hose structure is usually divided into: inner rubber layer, outer rubber layer and skeleton layer (or middle layer). The inner rubber layer directly be...
