Embodiment Construction

[0009] In an embodiment of the present invention, a method for manufacturing a composite coating on a substrate is provided, the method comprising the steps of:

[0010] applying at least one adhesive layer on the surface of the substrate;

[0011] applying at least one metal layer on the substrate coated with the adhesive layer;

[0012] At least one anti-corrosion layer is applied to the metal layer-coated substrate.

[0013] In the embodiment of the present invention, the base material can be a metal base material, such as metal materials such as plain carbon steel, stainless steel, or hard alloy metal; it can also be a non-metal base material, such as plastic or polymer materials.

[0014] First, an adhesive layer is applied on the surface of the substrate. The adhesive layer is formed by applying an adhesive on the surface of the substrate, and the steps include:

[0015] First, clean the surface of the substrate, which can be decontaminated with a detergent, then ultr...

Abstract

The invention provides a method for manufacturing a composite coating on a base material. The method comprises the following steps: 1, coating at least one bonding layer on the surface of the base material to obtain the base material with the bonding layer; 2, coating at least one metal layer on the base material with the bonding layer to obtain the base material with the metal layer; and 3, coating at least one anticorrosion layer on the base material with the metal layer. According to the composite coating in the embodiment of the invention, the bonding layer is a bottom layer, the metal layer is an intermediate layer, and the anticorrosion layer is a surface layer, so the coating can be attached to the base material without polishing; adhesion force between the coating and the base material is strong, and the surface layer hardness which is high can reach 4H; the surface layer which has a metal cluster has a reflective property, so the anticorrosion effect same as anticorrosion effects of common electroplating effects can be reached; and no electroplating is needed, so no discharge pollution, low energy consumption and low cost are realized in the production process.

Description

technical field [0001] The invention relates to a method for manufacturing a composite coating on a base material and a profile coated with the composite coating. Background technique [0002] Usually, surface treatment is required for the base material to achieve anti-corrosion or wear-resistant effects. The usual method of surface treatment of the substrate is to use electroplating technology to attach a single or composite corrosion-resistant material to the surface of the substrate. Electroplating technology usually uses the substrate as the anode, the material to be plated as the cathode, and applies a voltage so that the material to be plated is evenly deposited on the surface of the substrate, thereby increasing the wear resistance and reflective properties of the substrate, improving the aesthetic effect of the metal, etc. . By choosing different coatings, it can also play a role in corrosion resistance to a certain extent. However, in the electroplating process, ...
