Embodiment 1

[0024] A nickel-free environmental protection electroplating process described in this embodiment comprises the following method steps:

[0025] 1) Pre-treatment: Wipe the surface of the plastic structural parts with absolute ethanol, then put it into the plasma generator to evacuate and inject the mixed gas for surface plasma treatment, wash with water after the plasma treatment, the vacuum degree of the plasma treatment process is 30-100Pa, mix Gas flow rate is 120-180sccm, plasma generator power supply parameters: high frequency power supply 40KHz, radio frequency power supply 13.56MHz, plasma treatment time is 30s-15min;

[0026] 2) Pre-soaking treatment: the pre-treated plastic structural parts are sent to the pre-soaking tank for pre-soaking, and after pre-soaking, they are put into the cleaning tank and cleaned with deionized water. The pre-soaking liquid in the pre-soaking tank is 15-25g / L Aqueous stannous chloride solution, the pre-soaking treatment time is 1-3min;

Abstract

The invention belongs to the technical field of electroplating of plastic parts, and in particular relates to a nickel-free environmental protection electroplating process. The nickel-free environmental protection electroplating process of the present invention adopts nickel-free environmental protection electroplating, which reduces the toxicity of nickel to the human body; the processing process is simple and easy to implement, the process cost is low, the process flow is shortened and simplified, the processing time is short, and the production efficiency is high; pre-treatment Using plasma treatment, carbonyl, carboxyl, hydroxyl and other hydrophilic groups are formed on the surface of plastic structural parts, which can effectively roughen the surface of plastic structural parts and reduce the cumbersome process of conventional wet pretreatment; the conditions are mild and will not affect the plastic structural parts The structure and performance are affected; the palladium-free sensitizing solution and activation solution are used to replace the traditional colloidal palladium activation process, which avoids pollution while saving man-hours and reducing process costs; the metal coating is uniform and dense, with good stability; the process is low-toxic and environmentally friendly. Will not produce toxic carcinogenic and environmental pollution substances.

Description

technical field [0001] The invention belongs to the technical field of electroplating, and in particular relates to a nickel-free environmental protection electroplating process. Background technique [0002] Electroplating is a process that uses 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, conductivity, reflectivity, corrosion resistance (copper sulfate, etc. ) and improve aesthetics. [0003] According to the EU Nickel Release Directive, 94 / 27 / EC document, the product needs to be certified by SGS. If it exceeds the nickel release standard (Nickel Release Directive) required by the EU 94 / 27 / EC directive, it is not conducive to market and export business expansion. Nickel is the most common allergenic metal, and about 20% of people are allergic to nickel ions. When in contact with the human body, nickel ions can penetrate into the skin through pores and sebace...
