Abstract

The invention discloses a water-based metal rust inhibitor, comprising mixed alcohol amine, inorganic base, boric acid, rust inhibitor, copper alloy inhibitor, sterilizing preservative, foam suppressor, deionized water, etc. The composition is mainly applied to rust prevention during manufacture, storage and transpiration in metal processing industry, has no nitrate or heavy metal, and is environment-friendly and easy to operate.

Description

technical field [0001] The invention relates to metal antirust technology in mechanical processing, in particular to components of water-based metal antirust composition. Background technique [0002] In the metal processing industry, the corrosion of the metal of the processed parts is a problem that is often encountered, and it is very important to prevent the rust of the metal processing process, storage period, and transportation period of the processed parts. At present, there are mainly two types of antirust agents: water-based and oil-based. Water-based metal antirust agents are widely used in the inter-process rust prevention of metal machining processes, or metal rust prevention with a storage period of 3 to 4 months. In terms of oil-based anti-rust, water-based metal anti-rust agent has the characteristics of easy operation, simple process, easy cleaning of subsequent processes, and no impact on subsequent processing, and is more and more favored by customers. At ...
