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

[0018] A kind of antirust agent containing modified sepiolite powder, it is made by the raw material of following parts by weight (kg):

[0019] Castor oil 99, ferrocene 1.3, polyisobutene 1.6, ammonium dihydrogen phosphate 0.6, ammonium benzoate 1.2, 2-methylimidazole 1.3, β-naphthylamine 0.6, N-phenyl-2-naphthylamine 1.2, dioxane Zinc dithiophosphate 1.1, sodium lauryl sulfate 0.7, polyethylene glycol 1.5, film-forming resin 5.2, modified sepiolite powder 1.2.

[0020] The film-forming resin is prepared from the following raw materials in parts by weight: rosin 5.2, urea 3, zinc powder 1, dimethyl silicone oil 2, liquefied paraffin 10, 3-aminopropyltrimethoxysilane 2.4, acetylcitric acid Tris (2-ethylhexyl) ester 7.3, epoxy linseed oil 12, xylene 13, polyvinyl alcohol 8;

[0021] The preparation method of the modified sepiolite powder is as follows: the sepiolite is calcined at 720°C for 10 hours, ground into powder, soaked in 12% acetic acid solution for 6 hours, washed wi...

Abstract

The invention discloses an antirust agent containing modified sepiolite powder. The antirust agent is prepared from the following raw materials in parts by weight: 97-103 parts of castor oil, 1-2 parts of ferrocene, 1-2 parts of polyisobutene, 0.5-0.7 part of ammonium dihydrogen phosphate, 0.9-1.8 parts of ammonium benzoate, 1-2 parts of 2-methylimidazole, 0.4-0.8 part of beta-naphthylamine, 0.7-1.6 parts of N-phenyl-2-naphthylamine, 1-2 parts of zinc dialkyl dithiophosphate, 0.7-1.3 parts of sodium dodecyl sulfate, 1-1.8 parts of polyethylene glycol, 4.4-5.6 parts of film-forming resins and 0.8-1.6 parts of modified sepiolite powder. The 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 an antirust agent containing modified sepiolite powder. 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 an...
