Abstract

The invention discloses a formula and a preparation method of a nanometer heavy anti-corrosion coating. The formula comprises 45%-50% of epoxy resin, 3%-5% of toughened resins, 0.5%-1% of flatting agent, 1.5%-2% of wax powder, 2%-2.5% of fumed silica, 4%-6% of butyl glycidyl ether, 1.8%-2% of carbon black, 15%-21% of nano slurry, 4%-5% of phenylcarbinol, 0.4%-0.5% of dispersing agent, 0.8%-1% of antifouling additives and 3%-4% of alicyclic amine. The nanometer heavy anti-corrosion coating prepared according to the formula and the preparation method has the advantages of excellent heavy anti-corrosion performance, no volatilization, high solid content, thick formed film, long anti-corrosion service life and excellent metal base material adhesion performance, and plays an important role in the fields of petrochemical engineering, metallurgy and mining requiring heavy anti-corrosion.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion materials, in particular to a formulation and a preparation method of a nano heavy-duty anti-corrosion coating. Background technique [0002] In recent years, with the development of chemical industry, mining and other industries, the corrosion conditions have become more and more serious. The anti-corrosion performance life of traditional coatings cannot meet the requirements of heavy-duty anti-corrosion, which makes frequent replacement and re-coating operations, resulting in a waste of human and financial resources. Compared with traditional anti-corrosion coatings, nano heavy-duty anti-corrosion coatings are more targeted and functional. The use of nano-materials has a small particle size, which is at the nanometer level and has a large surface area. A small amount of addition replaces a large amount of traditional heavy-duty anti-corrosion coatings. Anti-rust fillers such as zinc powde...
