Problems solved by technology

[0003] Therefore, automotive interior parts need to carry out a series of treatment work on their surface after injection molding, and the existing automotive interior parts often shorten this process in order to save the process in the process of surface treatment, resulting in automotive interior parts The effect of surface treatment is poor, the service life is shortened, the aesthetics is poor, and the quality compliance rate of its production is also low, resulting in an increase in the scrap rate, thereby wasting costs and resources
[0004] In addition, when the pearl nickel operation is carried out on automotive interior parts, the method of preparing and using the sol

Embodiment

[0053] Embodiment: the surface electroplating treatment process of automobile interior parts, comprises the following steps:

[0054] 1. Chemical degreasing

[0055] (1) Clean the tank and auxiliary equipment;

[0056] (2) Inject about half of tap water into the tank;

[0057] (3) Add the required amount of degreasing powder U-151 into the air stirring;

[0058] (4) Add water to the required liquid level, stir with air until it is uniform, and then close;

[0059] (5) Heating to the process standard temperature for use;

[0060] 2. Coarsening

[0061] (1) Clean the tank and auxiliary equipment, and inject about 40% pure water into the tank;

[0062] (2) Under strong air stirring, slowly add the required amount of chromic acid until it is completely dissolved;

[0063] (3) Add sulfuric acid several times in small amounts, the temperature of the solution will rise, stop adding when the temperature is higher than 70°C, and add when the temperature drops below 60°C;

Abstract

The present invention discloses a vehicle interior decoration surface electroplating treatment process, which comprises: 1) ultrasonic wave degreasing; 2) coarsening; 3) palladium activation; 4) peptization; 5) chemical nickel achieving; 6) nickel pre-plating, 7) acid-copper treatment; 8) semi-bright nickel achieving; 9) pearl nickel achieving; 10) nickel sealing; 11) chromium decoration; and 12) electrolytic retreating. According to the present invention, the process is fine, the setting of the steps is detailed and reasonable, and the operation is ordered and simple so as to improve the vehicle interior decoration surface treatment effect, improve the yield, and provide advantages of god aesthetics, long use cycle, cost saving and resource saving; and after the boric acid in the electroplating process is rationally treated, the nickel plating efficiency and the nickel plating effect are significantly improved.

Description

technical field [0001] The invention relates to a surface electroplating treatment process of an automobile interior decoration. Background technique [0002] Automotive interior parts occupy a large proportion in the automobile manufacturing industry. For example, car handles, interior panels, inner panels, and front wall decorative panels are all automotive interior decoration parts. These decorative parts are injection molded first, and then Through surface treatment technology, it can achieve higher quality, better appearance and stronger performance, so that the function of the interior of the car can be further extended, and the surface-treated decorative parts are made of plastic materials because of their main body, and their surface Electroplated metal, such decorative parts can ensure lighter quality and better aesthetics. [0003] Therefore, automotive interior parts need to carry out a series of treatment work on their surface after injection molding, and the ex...
