Problems solved by technology

Anti-corrosion coatings in the prior art include anti-corrosion coatings containing antiseptic components such as chromate, aluminate, phosphate, etc. Among them, the anti-corrosion effect containing chromate is the best, but it is highly toxic and easy to cause cancer, so it is banned by the country; However, the anticorrosion effect of the anticorrosion coating containing only aluminum acid and phosphate is average, and the scope of application is narrow.
In addition, it also includes anti-corrosion coatings containing imidazoline compounds, benzothiazole compounds and other preservative components. This type of anti-corrosion coating has good anti-corrosion performance but poor environmental protection. However, with changes in the external environment and long-term use Among them, organic preservatives are easy to dissolve and release, which will lead to bad phenomena such as blistering and wrinkling of the coated coating, which limits its use

Description

technical field [0001] The invention belongs to the field of coatings, and relates to an anti-corrosion coating and a preparation method thereof. Background technique [0002] Corrosion refers to the process of loss and destruction of metal, concrete, wood and other materials under the chemical and electrochemical effects of the surrounding medium. The annual economic loss caused by corrosion in the world accounts for about 2% of the gross national product of each country. -4%, so anti-corrosion research has been paid more and more attention by countries all over the world. [0003] Among the many ways to reduce the loss caused by corrosion, coating technology is the most effective and economical method. Anti-corrosion coatings in the prior art include anti-corrosion coatings containing antiseptic components such as chromate, aluminate, phosphate, etc. Among them, the anti-corrosion effect containing chromate is the best, but it is highly toxic and easy to cause cancer, so ...
