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 containing urotropine, it is made by the raw material of following parts by weight (kg):

[0020] Castor oil 97, ferrocene 0.8, polyisobutylene 1.2, lanolin 1.1, zinc naphthenate 1.3, tert-butyl chromate 1.1, 2-methylimidazoline 1.3, benzotriazole 1.1, ethanolamine 1.2, urethane Tropin 0.9, zinc dialkyldithiophosphate 1.6, di-n-octyl-4-isothiazolinone 0.9, sodium dodecylbenzenesulfonate 1.5, film-forming resin 4.8, modified diatomite 1.

[0021] The film-forming resin is prepared from the following raw materials in parts by weight: rosin 6, urea 3, zinc powder 1, dimethyl silicone oil 4, liquefied paraffin 13, 3-aminopropyltrimethoxysilane 4, acetylcitric acid Tris (2-ethylhexyl) ester 11, epoxy soybean oil 11, xylene 11, polyvinyl alcohol 5;

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

Abstract

The invention discloses a metal antirust agent containing methenamine. The metal antirust agent containing the methenamine is prepared form raw materials comprising, based on the flowing weight part ratio, 93-102 parts of castor oil, 0.8-1.6 parts of ferrocene, 1-2 parts of polyisobutene, 0.7-1.4 parts of wool grease, 1.1-1.6 parts of zinc naphthenate, 0.9-1.8 parts of chromic acid tert-butyl ester, 1.1-1.8 parts of 2-methyl imidazoline, 0.9-1.5 parts of benzotriazole, 1-2 parts of cholamine, 0.8-1.3 parts of methenamine, 1.1-1.9 parts of dialkyl phosphorodithioic acid zinc, 0.7-1.2 parts of din-octyl-4-isothiazolinone, 0.5-1.5 parts of sodium dodecyl benzene sulfonate, 4.8-5.6 parts of film forming resin, and 1-2 parts of modified kieselguhr. The metal antirust agent containing the methenamine has excellent contact antirust performance and a good vapor phase antirust effect, and particularly has good vapor phase antirust and contact antirust effects for steels and brass.

Description

technical field [0001] The invention relates to the technical field of metal antirust, in particular to a metal antirust agent containing urotropine. 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 oil-sol...
