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 metal antirust agent containing ammonium molybdate. The metal antirust agent is prepared from the materials in parts by weight: 95-105 parts of castor oil, 1.2-2.4 parts of ferrocene, 0.8-1.6 parts of polyisobutene, 1-2 parts of ammonium molybdate, 1.3-2.5 parts of sodium diacetate, 0.8-1.6 parts of 2-methyl imidazoline, 1-1.8 parts of diethanol amine, 0.3-0.9 parts of dialkyl group phosphorodithioic acid, 0.7-1.2 parts of sodium dodecyl benzene sulfonate, 0.9-1.7 parts of polydimethylsiloxane, 5.2-6.4 part6s of film-forming resin and 1-2 parts of modified kaolin. The metal antirust agent has excellent contact antirust performance and good gas phase antirust effect, and has good gas phase antirust effect and contact antirust effect to coppers and brass.

Description

technical field [0001] The invention relates to the technical field of metal antirust, in particular to a metal antirust agent containing ammonium molybdate. 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. the [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 composed of base oil and...
