Embodiment 1

[0019] Embodiment 1 is the most preferred embodiment.

[0020] The product targeted in this example is a Type-C interface, and nickel plating needs to be performed on the surface of the product. Here, the additive of the nickel plating solution is improved, and the additive is composed of a brightener, a wetting agent and a leveling agent.

[0021] Among them, the addition amount of the brightener in the nickel plating liquid is 2ml / L, the addition amount of the wetting agent in the nickel plating liquid is 0.4ml / L, and the addition amount of the leveling agent in the nickel plating liquid is 2ml / L.

[0022] Wherein, the nickel-plating potion is a conventional nickel-plating potion, which contains the following conventional ingredients:

[0023] (1) the main salt, which can deposit the salt of the metal required for coating on the cathode;

[0024] (2) a complexing agent, which can form a complex with the deposited metal ions in solution;

[0025] (3) Conductive salts, which...

Embodiment 2

[0031] Others are the same as described in Example 1, the difference is: the amount of brightener added in the nickel-plating syrup is 1ml / L, the amount of wetting agent added in the nickel-plating syrup is 0.2ml / L, and the leveling agent is added in the nickel-plating syrup. The addition amount in the potion is 1ml / L.

Embodiment 3

[0033] Others are the same as described in Example 1, the difference is: the amount of brightener added in the nickel-plating syrup is 3ml / L, the amount of wetting agent added in the nickel-plating syrup is 0.3ml / L, and the leveling agent is added in the nickel-plating syrup. The addition amount in the potion is 3ml / L.

Abstract

The invention provides an additive for improving the surface treatment product bending test reliability. The additive is prepared from a brightening agent, a wetting agent and a leveling agent, wherein the additive amount of the brightening agent in a surface treatment solution is 1 to 5ml / L; the additive amount of the wetting agent in the surface treatment solution is 0.2 to 0.8ml / L; and the additive amount of the leveling agent in the surface treatment solution is 1 to 5ml / L. The additive for improving the surface treatment product bending test reliability provided by the invention can effectively solve the problem that cracks easily occur at a bending part after a product bending test.

Description

technical field [0001] The invention relates to the field of surface treatment, in particular to the field of nickel-plated products, and more particularly to an additive for improving the reliability of a bending test of surface-treated products. Background technique [0002] Surface treatment is a process of artificially forming a surface layer with different mechanical, physical and chemical properties of the substrate on the surface of the substrate. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. [0003] Surface treatment in a broad sense refers to the process methods including pretreatment, electroplating, painting, chemical oxidation, thermal spraying and many other physical and chemical methods. Among them, if it is subdivided according to the coating material of the product, it can include copper plating, nickel plating, silver plating, gold plating, etc. ...
