Embodiment Construction

[0055] The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the manufacturer's conditions, and the unspecified implementation conditions are usually conventional experimental conditions.

[0056] A kind of sandy nickel electroplating process of automobile radiator grille according to the present invention comprises the following steps:

[0057] 1) Degreasing

[0058] Carry out degreasing and dust removal treatment on the surface of the plastic substrate of the injection-molded automobile radiator grille, and then put it into the cleaning tank and rinse it with water;

[0059] 2) coarsening

[0060] Send the plastic substrate into the roughening liquid tank for roughening treatment, then put it into the cleaning tank and rinse it with clean water. The roughening temperature is 50-60°C, and the roughening ti...

Abstract

The invention provides a process for electroplating sand nickel on an automobile heat-dissipation grating. The process comprises the following steps: 1), oil removal; 2), expansion; 3), roughening; 4), reduction; 5), preimpregnation; 6), activation; 7), dispergation; 8), electroplating. According to the process, an electroplating pretreatment process for a plastic base material is improved, the whole process is environment-friendly and nonhazardous, chemical plating is not required to be used since a specially-made sand nickel electroplating solution is used, the operation is easier, the process stability is improved, the wastewater treatment is simple, the production time is greatly shortened, a hanging tool is not required to be replaced in the production process, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a sand nickel electroplating process for an automobile radiator grille. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of the base material by the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal Oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and improve appearance. [0003] Among them, in addition to iron-based cast iron, steel and stainless steel, the electroplating substrate materials also include non-ferrous metals, or ABS plastics, polypropylene, polysulfone and phenolic plastics, and electroplating on the surface of plastic substrates is called plastic electroplating. . Plastic electroplating products have the advantages of light weight, easy proc...
