Abstract

The invention relates to providing an anti-discoloration agent for metal materials, wherein the discoloration agent includes organic silicate, water-soluble chitin, polyurethane resin and benzotriazole sodium salt; the discoloration agent has a concentration of 0.25-0.35mp , wherein the content ratio of organosilicate is 25-69% by weight based on the total weight of the agent, the content ratio of water-soluble chitin is 15-35% by weight based on the total weight of the agent, and the polyurethane resin The content ratio is 5 to 15% by weight based on the total weight of the agent, and the content ratio of benzotriazole sodium salt is 25 to 49% by weight based on the total weight of the agent. The anti-discoloration agent for metal materials of the invention is not easy to corrode, has low volatility, strong anti-discoloration ability, wide application range and low raw material cost.

Description

technical field [0001] The invention relates to a metal treatment agent, in particular to an anti-tarnish agent for metal materials. Background technique [0002] In metal surface treatment, the surface of metal materials usually needs to be electroplated to attach a layer of metal film. However, after long-term use, due to contact with air, various oxygen and other gaseous media in the air will corrode the metal surface and discoloration, which will seriously affect its performance. Therefore, providing an anti-tarnish agent for metal materials has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide an anti-tarnish agent for metal materials so as to solve the problem of discoloration on the surface of some metal materials. [0004] The present invention is achieved through the following technical schemes: providing an anti-tarnish agen...
