Abstract

The invention discloses water-based antirust liquid for metal and belongs to the technical field of metal protection. The water-based antirust liquid comprises a polyvinyl alcohol solution, chitosan enzymatic hydrolysate, terephthalaldehyde, polyamide modified hydrogenated castor oil, chromium salt, organic acid, organic amine and an emulsifier. A preparation method of the water-based antirust liquid includes: stirring and mixing the polyvinyl alcohol solution and the chitosan enzymatic hydrolysate, sequentially adding the organic acid, the organic amine, the emulsifier, the polyamide modifiedhydrogenated castor oil and the chromium salt, stirring and mixing, adding the terephthalaldehyde, performing heating and stirring reaction, and discharging to obtain the water-based antirust liquid.The prepared water-based antirust liquid is lasting in antirust effect, good in adhesion, excellent in antirust effect and promising in application prospect in the development of metal protection industry.

Description

technical field [0001] The invention discloses a water-based metal antirust solution, which belongs to the technical field of metal protection. Background technique [0002] Anti-rust agent refers to the temporary anti-corrosion agent used in the transportation process (production, storage and transportation) of metal products. The metal antirust agent mainly forms a protective film on the metal surface to isolate it from the air and moisture in the environment, supplemented by some metal film agents to weaken the metal activity, slow down the metal oxidation, and rust speed. Different film formers and dispersants achieve the effect of rust prevention and metal protection. Water-based metal anti-rust solution is a water-based anti-rust solution, which can effectively protect steel, iron and other materials from rusting. According to different anti-rust requirements, it can be mixed with water according to a certain ratio. It is characterized by excellent anti-rust performa...
