Problems solved by technology

The film formed in this way is commonly called coating film, also known as paint film or coating. Traditional coatings are relatively simple and have no high temperature resistance effect. Therefore, we propose a coating for antirust and corrosion resistant steel

Abstract

The invention discloses a rust-proof and corrosion-resistant paint for steel. The paint is a composite paint prepared from multiple raw materials, and the paint is composed of, by weight, 20%-30% of epoxy resin, 10%-12% of a waterborne epoxy curing agent, 10%-20% of polystyrene and 5%-9% of ethylene glycol monomethyl ether, 4%-6% of calcium stearate, 2%-8% of lanolin magnesium soap, 5%-8% of polyacrylonitrile fiber, 7%-9% of an antioxidant, 4%-6% of aluminum tripolyphosphate, 5%-7% of zinc phosphate, 1%-3% of an additive, and the balance water. The invention has the beneficial effects that: the paint can endow steel with better rust resistance and corrosion resistance and stronger oxidation resistance after coating on the steel, can greatly enhance the service life of steel, has good market prospects, and is easy to popularize.

Description

technical field [0001] The invention belongs to the field of composite coatings, in particular to a coating for rust-proof and corrosion-resistant steel materials. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it like this: "Painting is a kind of material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, certain strength, and continuous coating. Solid film. The film formed in this way is commonly called coating film, also known as paint film or coating. T...
