Problems solved by technology

[0002] In the prior art, the production of variable-diameter rubber hoses is a difficult problem. The air flow rate and tensile strength of the variable-diameter rubber hoses produced are severely restricted, resulting in low performance of the variable-diameter rubber hoses.
Moreover, after long-term use, it is easy to cause the rubber hose to crack at the variable diameter, aging and hardening, etc., reducing the service life of the rubber hose

Abstract

The invention relates to the technical field of engine air intake hoses, in particular to a preparation method for an engine air intake variable diameter fabric hose. The preparation method comprisesthe specific steps that firstly, a surface layer rubber component and an inner layer rubber component are prepared, and a surface layer rubber sheet and an inner layer rubber sheet are jointly put into a forming roll in an upper and lower layers dividing mode; a fabric curtain cloth layer is put between the surface layer rubber sheet and the inner layer rubber sheet, and a composite rubber sheet is formed after passing through the forming roll; the composite rubber sheet is rolled into an tube shape, wherein the width direction of the composite rubber sheet is used as the axial direction, thejoint is flattened, bubbles are removed, and a hose body is formed, wherein the inner layer rubber sheet is located inside the hose body; and then the hose body is put into vulcanization equipment forvulcanization treatment, therefore the variable diameter fabric hose is obtained. According to the preparation method for the engine air intake variable diameter fabric hose, reasonable component proportion and control over parameters in the preparation process are carried out according to the internal and external performance requirements, the performance indexes of the variable diameter fabrichose are greatly improved, especially the tensile strength at the variable diameter position is large, and stability is high.

Description

technical field [0001] The invention relates to the technical field of engine intake rubber hoses, in particular to a preparation method of engine intake variable diameter fabric hoses. Background technique [0002] In the prior art, the production of variable-diameter hoses is a difficult problem. The air flow rate and tensile strength of the variable-diameter parts of the produced variable-diameter hoses are severely restricted, resulting in low performance of the variable-diameter hoses. Moreover, after a long period of use, it is easy to cause the rubber hose to crack at the variable diameter, aging and hardening, etc., reducing the service life of the rubber hose. Contents of the invention [0003] The object of the present invention is to provide a method for preparing an engine variable diameter fabric rubber hose with good wall thickness consistency and high tensile strength at the hose variable diameter in order to solve the above technical deficiencies.
