Problems solved by technology

However, the existing anti-rust agents are all composed of base oil and oil-soluble corrosion inhibitors, which can only play the function of contact anti-rust, and cannot form effective anti-rust protection for those parts that are not in contact with the anti-rust agent.

Abstract

The invention discloses a vapor-phase corrosion inhibition antirust agent containing 1,2-methylimidazole. The vapor-phase corrosion inhibition antirust agent comprises the following raw materials in parts by weight: 85-95 of casator oil, 1-2 of ferrocene, 0.5-1.4 of polyisobutylene, 0.9-1.2 of benzoic acid monoethanolamine, 0.4-0.9 of soidum methoxide, 0.9-1.6 of sodium dihydrogen zinc phosphate, 1-1.6 of 1,2-methylimidazole, 0.9-1.8 of triethanolamine, 0.7-1.3 of benzotriazole, 1-1.5 of zinc dialkyl dithiophosphate, 0.9-1.9 of sodium dodecylbenzene sulfonate, 5-6 of film-foaming resin and 1-2 of modified attapulgite. The vapor-phase corrosion inhibition antirust agent has excellent contact anti-rust performance and a very good vapor-phase anti-rust effect for steel and brass.

Description

technical field [0001] The invention relates to the technical field of metal antirust, in particular to a gas phase corrosion inhibitor and antirust agent containing 1,2-methylimidazole. Background technique [0002] Corrosion is one of the main forms of damage to metal products. According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2%-4% of the total output value of the national economy. [0003] In order to avoid corrosion and reduce losses, people have adopted various methods, and using antirust agents to protect metal products is one of the most common protection methods at present. Antirust agent grease is composed of one or more antirust additives (also known as oil-soluble corrosion inhibitors) and auxiliary additives added to the basic components of petroleum. It is easy to use, low in cost, good in effect, and simple in operation. Metalwork industries are heavily used. However, the existing anti-rust agents are all c...
