Abstract

The invention discloses a long-acting anti-rust solution. The long-acting anti-rust solution comprises, by weight, 30-40 parts of a compound corrosion inhibitor, 0.5-0.7 part of sodium carboxymethylcellulose, 3-5 parts of polyethylene glycol 400, 0.1-0.3 part of an antifoaming agent, 2-3 parts of sodium molybdate, 1-3 parts of disodium ethylene dinitrilotetra-acetic acid, 0.1-0.2 part of isothiazolinone and 38-45 parts of water, wherein phytic acid, CeNO3, diethanol amine boric acid ester, N-methyldiethanolamine and benzimidazole are adopted as the raw materials of the compound corrosion inhibitor. According to the long-acting anti-rust solution, through cooperation of the phytic acid, CeNO3, diethanolamine boric acid ester, N-methyldiethanolamine and benzimidazole, the long-acting anti-rust solution has the long-acting anti-rust performance.

Description

technical field [0001] The invention relates to the technical field of antirust liquid, in particular to an 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 kind of antirust liquid, and the present invention passes through phytic acid, Ce(NO 3 ) 3 , diethanolamine borate, N-methyldiethanolamine, and benzimidazole cooperate with each other, so that the present invention has long-acting antirus...
