At the same time, most of the water-based metal antirust agents in the early stage contained nitrite, double complex salts and other components. As we all know, nitrites are carcinogens, which are harmful to the health of operators. 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 provides a water-based metal antirust agent, which consists of the following components in parts by mass: 6-8 parts of sodium benzoate, 3-5 parts of sodium silicate, 3-5 parts of triethanolamine, 2-3 parts of barium sulfate 1-2 parts of acrylamide, 1-2 parts of sodium chloride, 1-2 parts of disodium hydrogen phosphate, 0.5-0.8 parts of isobutanol, 8-10 parts of ethanol, and 75-85 parts of water. The present invention also provides a preparation method of the above-mentioned water-based metal antirust agent. The water-based metal antirust agent of the present invention can be used for antirust in process, short-term storage and transportation, and can also be used in hydraulic equipment requiring antirust. The metal can be protected from rust by soaking, spraying, brushing, etc.; under normal circumstances, it can keep the metal rust-free for 130-160 days.
Description
technical field [0001] The invention relates to a water-based metal antirust agent and a preparation method thereof. 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 water-based metal antirust age...
