Abstract

An environmentally-friendly interprocess aqueous antirust liquid is composed of 3-14 parts by weight of triethanolamine oleate, 1-8 parts by weight of an inorganic corrosion inhibitor, 0.1-2 parts by weight of sodium benzoate, 1-10 parts by weight of glycerin, and 70-95 parts by weight of deionized water; and the inorganic corrosion inhibitor is one of sodium tungstate of sodium molybdate, or a sodium tungstate and sodium molybdate combination. Triethanolamine oleate and sodium benzoate in the above formula are organic corrosion inhibitors, and the aqueous solutions of the organic corrosion inhibitors and the aqueous solution of the inorganic corrosion inhibitor sodium tungstate and/or sodium molybdate have certain corrosion inhibition and antirust functions to steel. The compounding of the inorganic corrosion inhibitor and the organic corrosion inhibitors promotes and reinforces respectively corrosion inhibition and antirust performances of the inorganic corrosion inhibitor and the organic corrosion inhibitors. Sodium benzoate in the formula used as the organic corrosion inhibitor also has certain sterilization and anticorrosion effects; and glycerin in the formula used as an assistant is mainly used for adjusting the surface tension of the antirust liquid in order to improve the wetting property of the antirust liquid to the surface of a metal substrate.

Description

technical field [0001] The invention mainly relates to an antirust liquid, in particular to an environment-friendly inter-process water-based antirust liquid and a preparation method thereof. Background technique [0002] During the turnover of various processes in the processing and manufacturing process, steel products are prone to rust due to chemical or electrochemical interactions with the atmospheric environment. In severe cases, the product may even be scrapped and cause major economic losses. The use of anti-rust liquid to coat the surface of metal processing for "temporary anti-rust" is a common method of anti-rust between metal product processes; it is generally required that the anti-rust liquid applied before use or entering the next process can be easily removed. Anti-rust liquid includes two types: water-based anti-rust liquid and oil-based anti-rust liquid. The oil-based anti-rust liquid uses mineral oil as the dispersion medium, which is costly, difficult...
