Embodiment Construction

[0067] 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.

[0068] A kind of automobile label plastic electroplating process of the present invention, comprises the steps:

[0069] 1) Degreasing

[0070] Degreasing treatment is carried out on the surface of the injection-molded automobile signboard plastic base material, and then ultrasonic cleaning is performed, and then put into a cleaning tank and rinsed with clean water. The degreasing agent used for the degreasing is composed of NaOH, 10~20g / L Na 2 CO 3 , 10~15g / L Na 3 PO 4 12H 2 O and 2-5g / L anionic polyacrylamide; the deoiling temperature is 30-40℃, and the deoiling time is 5-10min;

Abstract

The invention provides an automobile label plastic electroplating process which comprises the following steps: 1) oil removal; 2) expansion; 3) roughening; 4) reduction; 5) presoaking ; 6) activation; 7) dispergation; 8) copper replacement; 9) copper plating under an acidic condition; 10) copper-tin alloy plating; 11) chrome plating; 12) drying. The set of brand-new plastic electroplating process is provided through complete improvement of a whole set of conventional plastic electroplating process, the whole process is environment-friendly, non-toxic, and free of chemical plating; the operation is easier, the process stability is improved, the wastewater treatment is simple, the production time is greatly shortened, a hanger needs no replacement in the production process, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a plastic electroplating process for automobile signboards. 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 processing, surf...
