Abstract

The invention discloses an electroplating-free antique metal surface treatment method. After a material surface is subjected to deoiling and surface activation, a primer is firstly sprayed and cured and then a finish paint is sprayed, wherein the primer consists of color paste, metal powder, polyurethane resin or acrylic resin and an assistant. According to the method, electroplating, chemical dyeing solution treatment and the like are not required, so that the environment pollution caused by the electroplating and the chemical dyeing solution is greatly reduced, processes such as grinding and wire drawing are also reduced, a production process is simplified, the production cost is reduced, and the technological process is environment-friendly; a texture effect of an antique metal layer is formed on the material surface, so that the product function and quality are improved.

Description

technical field [0001] The invention belongs to the field of material surface treatment, and in particular relates to an electroless plating antique metal surface treatment method. Background technique [0002] Traditional antique metal crafts generally have the following types: 1. Metal (copper, iron, nickel) bite corrosion → chemical blackening → wire drawing, grinding → painting; 2. Substrate electroplating (copper, copper alloy, nickel, tin) →Chemical black dyeing→wire drawing, grinding→painting; 3. Vacuum metallization (or spraying metal texture paint)→spraying black paint→drawing, grinding→spray topcoat. The first two methods are complex in process, high in cost, have sewage discharge, and have poor environmental protection performance. The last method has low efficiency and complicated process. The thickness of the black paint affects the whole process, and the repeatability is poor, so it is not practical. [0003] Electroless plating antique metal surface treatmen...
