Electroplated metal antiblushing agent and preparation method and using method thereof

Abstract

The invention relates to an electroplated metal surface treatment method, in particular to an electroplated metal antiblushing agent and a preparation method and a using method thereof. The electroplated metal antiblushing agent comprises the following components according to the following contents: 1-100g / L of inosilicate, 0.1-10g / L of organosilicate, 0.1-10g / L of fluoride and the balance of deionized water. The electroplated metal antiblushing agent is safe, environment-friendly, good in stability, good in protective effect and low in cost. The using method of the electroplated metal antiblushing agent comprises the following steps of: completely clearing away oil stains, dust and rusts on the surface of electroplated metal; soaking or spraying the electroplated metal by using the electroplated metal antiblushing agent; and baking the electroplated metal at high temperature to form an electroplated metal protecting film. The electroplated metal protecting film formed in the using method is resistant to high temperature, acid mist and corrosion, so that a plating layer is not corroded by environment and thus the stability, the reliability and durability of a metal component is protected; therefore, the electroplated metal antiblushing agent is wide in application prospect.

Description

technical field [0001] The invention relates to a surface treatment method for electroplated metal, in particular to an anti-tarnish agent for electroplated metal, a preparation method and a use method thereof. Background technique [0002] Corrosion of metal materials refers to a destructive phenomenon caused by chemical or electrochemical interactions between metal materials and surrounding media. Corrosion of metal materials can cause running, leaking, dripping, and leaking of equipment, polluting the environment, and even vicious accidents such as poisoning, fire, and explosion, as well as serious waste of resources and energy. Therefore, it is of great significance to study the corrosion mechanism of metal materials, find out the cause of corrosion and take effective protective measures for prolonging the life of equipment, reducing costs and improving labor productivity. [0003] There are many anti-corrosion methods for metal materials, mainly including improving the...

AI Technical Summary

Problems solved by technology

[0007] Anti-tarnish agents in the prior art are usually only suitable for a kind of electroplated metal and alloy, especially for electroplated zinc or zinc alloys, no suitable anti-tarnish agent has been reported, which limits its application in some fields, and most of them are currently The water-soluble anti-tarnish agent is all produced by emulsification process. The appearance of the product is milky. If it is placed for a long time, it will be stratified and precipitated, and the stability of the solution will decrease, which will affect the metal protection effect. There are still some environmental protection, Due to the disadvantages of difficult operation and high processing cost, it is particularly important to develop an anti-tarnish agent suitable for various electroplated metals with good protective effect.
