Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an improved process for galvanizing rubber and metal parts. After the metal parts are galvanized, they are vulcanized with rubber and then the finished rubber and metal parts are repaired and passivated. This method can effectively solve the problem of galvanized rubber peeling after vulcanization of rubber and metal parts, and ensure the appearance quality of the galvanized layer

Embodiment

[0028] Production of 6,534 pieces of spherical hinges with jackets, the specific process is: metal parts galvanized (without passivation), metal parts pre-treatment for gluing, gluing, vulcanization, zinc layer surface treatment, water washing, passivation. 5 pieces of unglued products (the zinc layer of these 5 products were seriously damaged in many places, and the zinc layer on the surface of the metal parts was removed and re-galvanized before the glue was unglued). The pass rate was 99.92%, and the appearance quality of the zinc layer was good.

Abstract

The invention provides a process method for galvanizing a rubber metal part. In the method, a metal part is galvanized, and is vulcanized with rubber, and a finished rubber metal part is repaired and passivated. The method comprises the following process steps: galvanizing the metal part, performing gluing preprocessing, gluing, vulcanizing, performing zinc layer surface treatment, washing with water, and passivating. The process can effectively solve the problem that the vulcanized rubber metal part is integrally delaminated, and the appearance quality of a galvanizing coat is ensured.

Description

technical field [0001] The invention relates to a surface protection treatment process for rubber-metal composite products, in particular to a galvanizing process for rubber-metal parts. Background technique [0002] With the rapid development of rail transit and modern industry, the preparation of rubber-metal composite products has been widely used. During use, due to the long-term influence of high temperature, sunlight, acid-base medium and other external environments, the exposed metal skeleton surface is very easy to rust and be corroded, so the rubber-metal composite products must be protected. Since the surface wettability and surface free energy of metal and elastic polymer materials, especially non-polar rubber materials, are very different, it is difficult to bond firmly, so the surface treatment of metal becomes the key to affect the bonding performance. At present, the known process of galvanizing rubber and metal parts is: pre-treatment of metal parts, gluing,...
