Abstract

The invention discloses a rubber tube for a car and a manufacturing method thereof, belongs to the technical field of rubber products, and solves the problem that the rubber product is relatively poorin bonding strength as a result of a polar relationship between acrylonitrile-butadiene rubber and chloroprene rubber. The rubber tube comprises an inner rubber layer and an outer rubber layer, wherein the inner rubber layer comprises the following raw materials: acrylonitrile-butadiene rubber, a reinforcing filler, a softening plasticizer, 2, 2'- dithiobisbenzothiazole, 4 , 4'- dithiodimorpholine, tetramethyl thiuram disulfide, auxiliaries and C10-series petroleum resin; and the outer rubber layer comprises the following raw materials: chloroprene rubber, acrylonitrile-butadiene rubber, a reinforcing filler, a softening plasticizer, 2, 2'- dithiobisbenzothiazole, tetramethyl thiuram disulfide, auxiliaries and C10-series petroleum resin. The rubber tube provides a rubber product for the car.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a rubber hose for automobiles and a preparation method thereof. Background technique [0002] The rapid development of the automobile industry promotes the development of the rubber industry. Over the past few years, rubber products for automobiles have developed into a unique and specialized product industry. Automotive rubber products are an indispensable and important component of auto parts. Among them, rubber hose products are automotive rubber products used in the chassis, engine and body. Hose products include fuel pipes, vacuum brake hoses, oil pipes, etc. [0003] With the development of automobile modernization, the requirements for rubber products for automobiles are becoming increasingly strict and demanding. Not only are rubber materials with their own special properties required to meet the new technical requirements of automobiles, but rubber materials a...
