preparation example Construction

[0052] Specifically, the preparation method of the water-soluble metal antirust agent involved in the present invention comprises the following steps:

[0053] a) mixing 1-5 parts by weight of C4-C20 fatty acids with 1-3 parts by weight of alcohol amine compounds to obtain a mixed material;

[0054] b) Under protective gas, heating the mixed material to a first predetermined temperature to make it react, and then adding 1-4 parts by weight of the C8-C18 phosphoric acid ester therein to obtain the film-forming agent.

[0055] Thus, the film-forming agent can be prepared through a simple preparation process, and the film-forming agent can be attached to the metal surface, so that the water-soluble metal antirust agent has better wear resistance and antirust performance.

[0056] With regard to step a), it should be understood that there is no special limitation on the mixing method of the C4-C20 fatty acid and the alcohol amine compound, as long as the C4-C20 fatty acid and the ...

Embodiment 1

[0066] Mix 1-5 parts of naphthenic acid and 1-3 parts of diisopropanolamine in a reaction kettle, under nitrogen protection, raise the temperature to 100-160°C, after 50 minutes, add 1-4 parts of lauric acid phosphate polyoxyethylene Ether, 1-3 parts of 1-decyl-3 methylimidazole borate compound, react for 30 minutes to prepare water-soluble metal rust inhibitor.

Embodiment 2

[0068] Mix 1-5 parts of sebacic acid and 1-3 parts of diisopropanolamine in a reaction kettle, under nitrogen protection, heat up to 100-160°C, after 50 minutes, add 1-4 parts of oleic acid phosphate polyoxygen Vinyl ether and 1-3 parts of 1-decyl-3 methylimidazole borate compound are reacted for 30 minutes to prepare a water-soluble metal rust inhibitor.

Abstract

The invention discloses a water-soluble metal antirusting agent and a preparation method thereof. The water-soluble metal antirusting agent contains a film-forming agent, wherein the film-forming agent is formed by fatty acid with C4-C20, alcohol amine and phosphate ester with C8-C18. According to the water-soluble metal antirusting agent disclosed by the embodiment of the invention, no harm is caused to a human body, energy is saved, the environmentally-friendly requirement is met, the preparation process is simple, and the water-soluble metal antirusting agent disclosed by invention contains the film-forming agent and can be adhered onto a metal surface, so that the water-soluble metal antirusting agent disclosed by the invention has the advantages of better abrasion resistance and antirusting performance.

Description

technical field [0001] The invention relates to the technical field of metal antirust, more specifically, the invention relates to a water-soluble metal antirust agent and a preparation method thereof. Background technique [0002] In metalworking processes, such as cutting and cold rolling, emulsions or fully synthetic cutting fluids are often used for cooling and lubrication. Due to the presence of large amounts of water in machining fluids, corrosion protection of surfaces during and after machining is critical. At present, antirust oil and antirust paint are mostly used for long-term antirust of metal processing or products, which have high cost and serious environmental pollution. It is difficult to treat waste liquid in the later stage, which brings a lot of inconvenience to use. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems. [0004] Therefore, an object of the present invention is to ...
