Problems solved by technology

[0002] Metals are easily corroded by the surrounding environment
People usually choose anti-rust oil or water-based anti-rust liquid for metal surface treatment, but anti-rust oil is not easy to remove, which will bring trouble to the subsequent process; water-based anti-rust liquid will not affect the subsequent process and is easy to clean, so it is widely used , but the anti-rust time of water-based anti-rust liquid is not long, which limits its use

Abstract

The invention discloses corrosion-resistant long-acting antirust liquid. Raw materials of the corrosion-resistant long-acting antirust liquid comprise, by weight, 35-45 parts of compound corrosion inhibitor, 0.1-0.3 parts of a surface active agent, 0.2-0.4 part of hydroxy propyl cellulose, 0.3-0.5 part of polyethylene glycol, 0.1-0.3 part of a defoaming agent, 1-3 parts of sodium gluconate, 0.2-0.3 part of benzisothiazolones and 50-54 parts of water, wherein raw materials of the compound corrosion inhibitor comprise phytic acid, sodium molybdate, diethanol amine, monoethanolamine borate and 2-methyl benzimidazoline. According to the corrosion-resistant long-acting antirust liquid, by means of cooperation of the phytic acid, the sodium molybdate, the diethanol amine, the monoethanolamine borate and the 2-methyl benzimidazoline, the film forming speed of a protective film is increased, the corrosion speed is decreased, the thickness of the protective film is increased, corrosion media are prevented from making contact with metal, and the corrosion-resistant long-acting antirust liquid is made to have good corrosion-resistant performance and long-acting antirust performance.

Description

technical field [0001] The invention relates to the technical field of antirust liquid, in particular to a corrosion-resistant long-term antirust liquid. Background technique [0002] Metals are easily corroded by the surrounding environment. People usually choose anti-rust oil or water-based anti-rust liquid for metal surface treatment, but anti-rust oil is not easy to remove, which will bring trouble to the subsequent process; water-based anti-rust liquid will not affect the subsequent process and is easy to clean, so it is widely used , but the anti-rust time of water-based anti-rust liquid is not long, which limits its use. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a corrosion-resistant long-acting anti-rust liquid, the present invention interacts with phytic acid, sodium molybdate, diethanolamine, monoethanolamine borate, and 2-methylbenzimidazoline Cooperate to increase t...
