Abstract

The present invention relates to electrical contact metal protective agents. The invention relates to a surface protective agent mainly used for electronic components and a preparation method thereof. 5.0% lubricant, the balance is solvent, made by mixing and heating. The selected materials are environmentally friendly materials, which will not pollute the environment during production, preparation and use. The protective agent composition of the invention is closely combined with the metal surface, and has strong wear resistance, lubrication, rust resistance, mildew resistance and corrosion resistance. It maintains a good insulating or conductive state during work, and will not cause instant arc sparks to burn the circuit due to poor contact. It can be widely used in electronic and electrical components, connectors, aluminum alloy conductive oxidation and protection of gold and silver jewelry surfaces.

Description

technical field [0001] The invention relates to an environment-friendly metal anti-corrosion organic film protective agent, which mainly involves forming a layer of anti-corrosion film coating on the surface of gold, silver and other metal contacts of electronic and electrical components, and has the characteristics of both insulation and conductivity. Background technique [0002] Between metal and metal, friction occurs due to contact, so that the metal surface is easily exposed to the air due to wear and scratches, especially in humid and harsh atmospheric environments, it is more likely to cause metal corrosion and damage due to electrochemical reactions. If it is damaged, it will cause instantaneous arc sparks due to poor contact, causing circuit failure, and even burning electronic equipment when it is more serious. However, the reliability of electronic equipment largely depends on the reliability of electrical contact elements (including switch elements, plug connect...
