Problems solved by technology

At the same time, most of the early water-based metal rust inhibitors contained nitrite, heavy zinc salt and other components. As we all know, nitrite is a carcinogen, which is harmful to the health of the operator. Contains heavy metals such as cyanide, which is harmful to the environment, and heavy metals are introduced into the workpiece during processing, which affects the performance and quality of the workpiece

Abstract

The invention discloses a metal antirust agent, comprising thermoset phenolic resin, inorganic alkali, polyethylene glycol, hydroxylamine complexing agent, sebacic acid, glycerol and ethanol. The invention has the beneficial effect that antirust liquids with different concentrations can be prepared for usage according to specific conditions; the antirust agent is environment-friendly and efficient, and omits the oil removal treatment on waste liquid; and the antirust agent is clean and easy for cleaning, has no influence on subsequent processing, and is mainly used for rust protection between process and in short-term storage and transportation process, and can also be used in hydraulic equipment requiring rust protection.

Description

technical field [0001] The invention relates to a metal antirust agent, which belongs to the field of chemical products. Background technique [0002] In the metal processing industry, the corrosion of the metal of the processed parts is a problem that is often encountered. 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 process of metal mechanical processing for rust prevention, or for metal rust prevention with a storage period of 3-4 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 the same time, most of the early water-based metal ru...
