Abstract

The invention discloses an antirust coating used for steel, and a preparation method thereof. The preparation method comprises the following steps: weighing epoxy resin, isopropanol, butanol, an aluminum paste, butyl acrylate, methyl methacrylate, acrylic acid, styrene, barium sulfate, zinc phosphate, modified aluminum triphosphate, sodium bicarbonate, ammonium persulfate and talcum powder, stirring above raw materials, and grinding the stirred raw materials to form the antirust coating. A coating film formed by the coating has flat and bright appearance, the viscosity is 100-120s, the surface drying time is 30-50min, and the hard drying time is 15-19h; the flexibility is 1-3mm, and the adhesion is 1-2 grade; the coating film has no foaming or shedding phenomenon after being immersed in 30DEG C water for 3-7d, and the impact resistance is 50-70cm; and the fineness is 25-45[mu]m, and the pencil hardness is H.

Description

Technical field [0001] The invention involves coatings on the surface of steel, especially for a steel -proof coating and preparation method for steel. Background technique [0002] Anti -rust coatings can protect the surface of the metal surface from chemical or electrochemical corrosion coatings on the surface of the metal.Applying rust -proof coatings on the metal surface can effectively avoid the direct invasion of various corrosive substances in the atmosphere, so that the maximum extension of the metal use period.It can be divided into two categories: physical and chemical rust -proof paint.The former relies on the appropriate cooperation of talc powder and paint to form a dense paint film to prevent the invasion of corrosive substances, such as iron red, aluminum powder, graphite rust -proof paint, etc.;Such as Hongdan, zinc yellow anti -rust paint, etc.Used for rust -proof anti -rust of metal such as bridges, ships, pipelines.The rust -proof paint used is roughly two type...
