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.

Embodiment Construction

[0019] A kind of metal antirust agent, it is made by the raw material of following parts by weight (kg):

[0020] Castor oil 100, ferrocene 1.5, polyisobutylene 1.3, dibutyl succinate 1.3, 2-aminoethyl heptadecenyl imidazoline 0.9, benzotriazole 1.3, β-naphthylamine 1.1, N-benzene Base-2-naphthylamine 1.1, dialkyl zinc dithiophosphate 1.1, polyvinyl alcohol 1.8, sodium dodecylbenzenesulfonate 0.8, film-forming resin 5, modified diatomite 1.1;

[0021] The film-forming resin is prepared from the following raw materials in parts by weight (kg): rosin 7, urea 3, zinc powder 1, dimethyl silicone oil 4, liquefied paraffin 15, 3-aminopropyltrimethoxysilane 3, Acetyl tri(2-ethylhexyl) citrate 12, epoxidized soybean oil 11, xylene 14, polyvinyl alcohol 8;

[0022] The preparation method of the modified diatomite is as follows: diatomite is soaked with 11% hydrochloric acid for 3 hours, washed with deionized water, then soaked with 12% sodium hydroxide solution for 3 hours, and then w...

Abstract

The invention discloses a metal antirust agent. The metal antirust agent is prepared from the following raw materials in parts by weight: 90-100 parts of castor oil, 1-2 parts of ferrocene, 0.8-1.6 parts of polyisobutene, 0.9-1.8 parts of dibutyl succinate, 0.7-1.4 parts of 2-aminoethyl heptadecenyl imidazoline, 1-2 parts of benzotriazole, 0.6-1.2 parts of beta-naphthylamine, 0.5-1.3 parts of N-phenyl-2-naphthylamine, 1-2 parts of zinc dialkyl dithiophosphate, 1-2 parts of polyvinyl alcohol, 0.4-0.9 part of sodium dodecyl benzene sulfonate, 5-6 parts of film-forming resins and 0.5-1.3 parts of modified diatomite. The metal antirust agent has excellent contact antirusting performance and good gas-phase antirusting effect and has good gas-phase antirusting effect and contact antirusting effect on steels and brasses.

Description

technical field [0001] The invention relates to the technical field of metal antirust, in particular to a metal antirust agent. 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 composed of base oil and oil-soluble corrosion inhibitors, w...
