Embodiment 1

[0025] Present embodiment one concrete raw material and weight are:

[0026]

[0027] The steps of the preparation method for making the cationic water-based antirust agent composition are as follows: Weigh 43.5 kg of ionized water, put 10 kg each of triethanolamine and monoisopropanolamine into deionized water, stir well and mix the dodecyl carbon binary Put 10 kg of acid and 5 kg of undecanedibasic acid into the above mixed solution, heat it to 40-60°C while stirring, stir evenly and react completely, and put in 15 kg of bis-imidazoline quaternary ammonium salt after no visible particles, carbon Add 5 kg of quaternary ammonium salt, stir and stir evenly, then add 1 kg of sodium molybdate and 0.5 kg of benzotriazole into the above mixture, and stir evenly to obtain the finished product.

[0028] The above-mentioned carbonate quaternary ammonium salt is didecyldimethylammonium carbonate.

[0029] After the antirust solution prepared according to the implementation example ...

Embodiment 2

[0033] The concrete raw material of present embodiment two and weight are

[0034]

[0035] The steps of the preparation method for making the cationic water-based antirust agent composition are as follows: Weigh 47.5 kilograms of ionized water, put 10 kilograms of monoethanolamine and triisopropanolamine into deionized water, stir well and add 15 kilograms of sebacic acid Put into the above mixed solution, heat to 40-60°C while stirring, stir evenly and react completely, after no visible particles, put in 10 kg of bis-imidazoline quaternary ammonium salt, 6 kg of carbonate quaternary ammonium salt, stir and stir evenly, Then put 1 kg of sodium molybdate and 0.5 kg of tolyltriazole into the above mixture, and stir evenly to obtain the finished product.

[0036] The above-mentioned carbonate quaternary ammonium salt is didecyldimethylammonium carbonate.

Abstract

The invention discloses a cationic aqueous antirust agent composition. The composition comprises, by weight, 10-20 parts of dibasic acid mixtures, 20-50 parts of organic amine, 10-20 parts of cationic antirust agents, 10-20 parts of cationic antirust film-forming agents, 1-2 parts of passivants, 0.5-1 part of a non-ferrous metal passivant and the balance deionized water. The composition has the advantages that the composition is a high enrichment product and provided with good antirust and corrosion inhibition performances when added with water to dilute to a concentration of 3-5%; the composition contains no polyphosphates or nitrite, causes no eutrophication, and is nontoxic for human bodies; the composition has a high generality, and good sealing up effect and interprocess antirust effect on non-ferrous metal and ferrous metal; and the operation is simple without warming, processes such as impregnation, painting and spraying can be adopted, the composition is easier to remove compared with an oily antirust material, and follow-up welding and spraying processes can be directly performed.

Description

Technical field: [0001] The invention relates to an antirust composition, in particular to a cationic water-based antirust composition. Background technique: [0002] Metal materials play a very important role in modern industrial and agricultural production. Various industries need a large amount of metal materials, and at the same time, they are inseparable from metal materials in daily life. Metal materials occupy a very important position in the modern economic life cycle. However, during the use of metal materials, they will be affected by the surrounding environment. to different forms of damage, the most common of which are fracture, wear and corrosion. Among them, corrosion is ubiquitous. Humans have discovered this phenomenon since the beginning of using metals, but the research and prevention of corrosion is still a matter of nearly a hundred years. The definition of metal corrosion is: the destruction of metal due to chemical reaction, electrochemical reaction o...
