Problems solved by technology

[0004] The present invention provides a flexible ceramic heavy-duty anti-corrosion coating and a preparation method thereof, which can effectively solve the problem that the anti-corrosion coating proposed in the above background technology is very brittle after film formation, the flexibility and impact resistance of the paint film are very poor, and it is easy to crack and fall off. Its practical application is limited. In addition, the feeding speed cannot be adjusted according to the needs during the grinding process, which reduces the effect of coating grinding and affects the quality of subsequent molding.

Abstract

The invention discloses a preparation method of a flexible ceramic heavy anti-corrosion coating, which comprises the following steps of: S1, adding epoxy resin, liquid polysulfide rubber, a dispersing agent, xylene and an epoxy active diluent into a production cylinder, and stirring for 5-10 minutes at the speed of 600-800 revolutions per minute; and S2, adding ceramic whiskers, ceramic powder, carbon nanotubes, glass flakes, fumed silica, polyamide wax and a coupling agent while stirring at the speed of 600-800 revolutions per minute, and dispersing at the high speed of 800-1000 revolutions per minute for 10-15 minutes. According to the invention, the structure is scientific and reasonable, the use is safe and convenient. The liquid polysulfide rubber and the high chlorinated polyethylene are adopted, the epoxy resin is modified by the curing reaction of the epoxy resin and a phenolic aldehyde amine curing agent, and the obtained coating has characteristics of good flexibility and good corrosion resistance under the action of the ceramic whisker and the carbon nanotubes. Meanwhile, the glass flakes further improve the corrosion resistance of the coating, and the ceramic powder and the whiskers effectively improve the corrosion resistance of the coating and improve the impact resistance of the coating.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coating preparation, in particular to a flexible ceramic heavy-duty anti-corrosion coating and a preparation method thereof. Background technique [0002] At present, in the field of heavy-duty anti-corrosion, heavy-duty anti-corrosion coatings are widely used due to their low cost, good effect, and convenient construction. The most common one is epoxy coatings. For common atmospheric areas, "zinc-rich primer + epoxy intermediate The anti-corrosion supporting system of "paint + weather-resistant topcoat" generally uses high-solid epoxy coatings or modified epoxy coatings for underwater immersion areas, and generally uses high-solid epoxy coatings for conventional chemical-resistant linings. paint or epoxy phenolic paint; [0003] However, the existing anti-corrosion coating film is very brittle after film formation, the flexibility and impact resistance of the paint film are very poor, and...
