Problems solved by technology
[0002] In the plastic electroplating process in the prior art, the plastic surface is usually pretreated by a chemical roughening method, which generally corrodes the surface of the plastic material through an acidic chemical solution to form dense fine lines or dents in a microscopic state. The chemical method requires two to three processes for chemical treatment. After the treatment is completed, a neutralization reaction is required to neutralize the acidic substances on the surface of the plastic. If the treatment is not clean, it will affect the later electroplating process. Technical defects such as overflow, loose plastic structure and slow molding are prone to occur

Embodiment 1
[0082] The first step: select ABS plastic as the base material, and use the base material molding device to mold the ABS plastic to obtain a plastic molded part, and roughen it;
[0083] Step 2: Put the plastic molded parts into 50g / l chemical degreasing agent and react at 50-60 degrees for 5 minutes to carry out chemical degreasing;
[0084] Step 3: Place the plastic molded part in an electrolytic tank for electrolysis to form a path on the surface of the plastic molded part;
[0085] Step 4: put the plastic molded part into a mixed solution of 1.5% presoaked salt and 50ml / l CP hydrochloric acid for colloidal palladium activation treatment, and react at a temperature of 35-45 degrees for 8-15 minutes;
[0086] Step 5: put the plastic molded parts activated by colloidal palladium into CP hydrochloric acid 100ml / l mixed solution for degumming treatment, and react at a temperature of 35-45 degrees for 1-3 minutes;
[0087] Step 6: Perform electroless nickel plating on the degum...

The invention discloses an electroplating molding process for plastic. The electroplating molding process for plastic comprises the following steps that first, ABS plastic is used as a base material and is molded through a base material molding device, so that a molded plastic piece is obtained and is roughened; second, chemical deoiling is conducted; third, racking is conducted; fourthly, colloidal palladium activation is conducted; fifth, peptization is conducted; sixth, chemical nickel plating is conducted; seventh, pyrophosphoric acid plating and copper plating are conducted; eighth, sulfate copper-plating is conducted on the molded plastic piece subjected to pyrophosphoric acid plating and copper plating; ninth, nickel brightening treatment is conducted on the molded plastic piece subjected to sulfate copper-plating; tenth, chromium plating is conducted on the molded plastic piece subjected to nickel brightening treatment; and eleventh, the molded plastic piece subjected to chromium plating is dried. The electroplating molding process for plastic has the advantages that the plastic electroplating procedure is omitted, and the molded part can be rapidly molded; and the electroplating molding process can be widely applied to the field of plastic electroplating.
Description
technical field [0001] The invention relates to the field of plastic electroplating. More specifically, the present invention relates to a plastic electroplating molding process. Background technique [0002] In the plastic electroplating process in the prior art, the plastic surface is usually pretreated by a chemical roughening method, which generally corrodes the surface of the plastic material through an acidic chemical solution to form dense fine lines or dents in a microscopic state. The chemical method requires two to three processes for chemical treatment. After the treatment is completed, a neutralization reaction is required to neutralize the acidic substances on the surface of the plastic. If the treatment is not clean, it will affect the later electroplating process. It is prone to technical defects such as overflow, loose plastic structure and slow molding. Contents of the invention [0003] The object of the present invention is to provide a plastic electro...
