Vehicle interior decoration surface electroplating treatment process

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...

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 solution is generally used, which can ensure the immediate use of the nickel plating solution after deployment and ensure the nickel plating quality of the pearl nickel. However, in the actual processing process, it is found that , the disadvantage of this operation is that the amount of pearl nickel solution used is relatively large, and the nickel plating solution of pearl nickel needs to be used within 4-6 hours after it is prepared, which undoubtedly increases the difficulty of production and easily causes plating problems. The waste of nickel solution increases the cost, and the treatment capacity of nickel plating wastewater is greatly increased when it is ready for use
