Problems solved by technology

[0005] The present invention aims at the problem of difficulty in bonding between silicone rubber with too low polarity and polished and passivated stainless steel in the prior art, and provides a surface treatment method for stainless steel, which is used to clean the surface of the stainless steel before bonding the silicone rubber to the stainless steel. Surface treatment of stainless steel, change the characteristics of the stainless steel surface, achieve good bonding between the two inert materials of silica gel and stainless steel, and greatly improve the bonding strength between the two inert materials of silica gel and stainless steel

Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below.

[0025] The stainless steel surface treatment method is characterized in that the steps are as follows:

[0026] 1) Degreasing: The degreasing agent KW-10B is mixed with water to form a degreasing liquid. The free base point of the degreasing liquid is 14~20. Heat the degreasing liquid to 60~80°C and keep it warm. Put the substrate into Put it in the degreasing solution at 60-80°C for 5-20 minutes, then take out the substrate and dry it at 80-110°C for 5-10 minutes to fully volatilize the residual liquid on the surface of the substrate;

[0027] 2) Sand blasting: Use a 10-30Kw shot blasting machine to load steel shots with a diameter of 0.6-1.0mm to shot blast the surface of the substrate for 10-30 minutes; or use a sand blasting machine to load 36 mesh white corundum pairs under an air pressure of 0.4-1.0Mpa The surface of the substrate is sandblasted for 10-30 minutes to make the surface sta...

Abstract

The invention discloses a stainless steel surface treatment method. The stainless steel surface treatment method is characterized by comprising the following steps that degreasing, oil stains and impurities on the surface of a base material are removed by using a degreasing liquid; sand blasting, shot blasting treatment or sand blasting treatment is carried out on the surface of the base material,so that the surface state of the base material is uniform and consistent; dust removing, dust which is left on the surface of the base material after the sand blasting is carried out is removed; gluing, glue mucus uniformly coats the surface of the base material; and drying, a dried adhesive layer is formed on the surface of the base material. The stainless steel surface treatment method is usedfor carrying out surface treatment on stainless steel before bonding the silica gel with the stainless steel to change the characteristics of the surface of the stainless steel, good adhesion betweentwo inert materials of the silica gel and the stainless steel is realized, so that the bonding strength between the two inert materials of the silica gel and the stainless steel is greatly improved. The invention further provides the silica gel and stainless steel bonding technology and a product.

Description

technical field [0001] The invention relates to a stainless steel surface treatment method, which belongs to the technical field of material surface treatment, and also relates to a silica gel and stainless steel bonding process and products. 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 protection of rubber-metal composite products is particularly important. 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.
