Problems solved by technology

[0005] However, during electroless plating, there are many metal substances left on the electroless plating activator, the preparation time is too long, and the surface will be attached too much, so it is necessary to treat the metal on the surface, but the existing processing methods are complex and changeable , can't handle the metal on the surface of the activator better and more reliably, so it needs to be improved

Abstract

The invention discloses a chemical plating activating agent surface metallization treatment method. The chemical plating activating agent surface metallization treatment method comprises the following steps that 1, a metal part is placed in a drying oven, and the internal stress of the metal part is removed; 2, the metal part is smeared with an emulsifying agent, and oil on the surface of the metal part is removed; 3, the metal part is soaked in a mixed acid solution, and roughening operation is conducted on the surface of the metal part; 4, the metal part is immersed in a sodium hydroxide solution for neutralization, and hexavalent chromium generated after roughening of the metal part is removed; and 5, a layer of substances easy to oxidize is adsorbed to the metal part through sensitization. Sodium hypophosphite is used as a strong reducing agent and serves as a chemical plating agent, so that a chemically plated metal surface layer has corrosion resistance, wear resistance, uniformity and compactness, the activity degree of metal molecules on the surface of the activating agent can be better accelerated through high-temperature firing, a worker can better carry out extraction operation on the treated metal, and therefore, the extraction operation of the surface metal is realized.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a surface metallization treatment method of an electroless plating activator. Background technique [0002] Electroless plating is a new type of metal surface treatment technology, which has attracted increasing attention because of its simple process, energy saving and environmental protection. Electroless plating is used in a wide range, and the gold plating layer is uniform and decorative. In terms of protection performance, it can improve the corrosion resistance and service life of the product; in terms of functionality, it can improve the wear resistance, electrical conductivity, lubrication performance and other special functions of the workpiece, so it has become a development of surface treatment technology in the world; [0003] Electroless plating technology is a deposition process in which metals are produced through controllable redox reactions under...
