Abstract

The invention relates to a straight rubber hose with a hot melt adhesive sheath and a preparation method for the straight rubber hose. The hot melt adhesive sheath of which the inner wall is provided with an adhesive body is adhered on the straight rubber hose, and consists of two parts of structures, namely a semiflexible thermal contraction tube of which the inner layer is attached with an hot melt adhesive and a thermal contraction tube of which the outer layer is made of radiation crosslinking polyolefin. The preparation method for the straight rubber hose with the hot melt adhesive sheath comprises a step of contracting the hot melt adhesive sheath to the surface of a rubber hose body under a high temperature condition by high-temperature heating equipment, wherein the thermal contraction temperature ranges from 140 DEG C to 160 DEG C; the inner diameter of the hot melt adhesive sheath before thermal contraction is 2 to 10 millimeters more than the outer diameter of the rubber hose; and the thickness of the hot melt adhesive sheath ranges from 0.4 millimeters to 2.6 millimeters. A high-molecular material has a high anti-abrasion performance, so that a phenomenon of surface abrasion caused by friction between the rubber hose and other surrounding parts is avoided. The hot melt adhesive has high adhesiveness and high flexibility, so that the sheath is difficult to loose or shift from the hose body.

Description

technical field [0001] The invention relates to a rubber hose assembly for automobiles, in particular to a straight rubber hose with a hot-melt adhesive sheath and a preparation method. Background technique [0002] With the development of the automobile industry, the structure of the parts inside the car is becoming more and more complex, and the interference problem between the various parts appears. The original rubber hose with a single structure can no longer meet the needs of assembly. In order to solve the problem of interference between components, a wear-resistant protective sleeve is usually placed on the outer part of the rubber hose that is easy to wear, so as to improve the wear resistance of the rubber hose. However, if the protective part of the rubber hose is a straight rubber tube, and the sheath and the rubber tube body are not bonded together, the sheath will often become loose and shifted, making the sheath in the area that needs to be protected. Protect...
