Description

Technical Field

[0001] The utility model relates to the field of coatings, in particular to an anti-rust alkyd primer coating. Background Art

[0002] When oil-based paint is applied to the surface of the protected object and solidifies, it will form a paint layer. In order to enhance the performance of the coating and increase its practicality, we generally apply several layers of paint on the surface of the protected object to form a paint layer structure to meet the needs of users. Existing anti-corrosion paints only have a single anti-corrosion function when used alone, and cannot meet the needs of salt spray resistance, oil resistance, water resistance, gloss and color retention, etc., which narrows the application surface of the paint layer and limits its application scope. Therefore, it is urgent to develop an anti-corrosion alkyd primer coating that can improve adhesion and make the coating tightly adhere to the coating surface; at the same time, it has strong weather resistance and gloss and color retention, and has excellent corrosion resistance to corrosive media.

[0006] Furthermore, the first anti-rust layer is a red lead alkyd anti-rust primer: the red lead alkyd anti-rust primer is made of alkyd resin, red lead powder, anti-rust pigment, solvent, and additives, which are ground and modulated. It has good adhesion and anti-rust performance, and dries quickly. It is mainly used for priming and anti-rusting on the surface of metal structures.

[0007] Furthermore, the second anti-rust layer is an epoxy zinc phosphate anti-rust coating; the epoxy zinc phosphate anti-rust coating film is hard, wear-resistant, has strong adhesion, and has good water resistance, salt spray resistance and anti-rust properties.
