Stable water-based coating for rusted surface

Abstract

The present invention provides a stable water-based coating for rusted surfaces which is non-toxic, harmless, non-radioactive, low in coating cost, suitable for metal surfaces having rust, solid oxide skin or old paint film, and has good rust-preventing effect for metal surfaces free of rust. The rust-preventing coating can be used for large metal structures where surface treatments are difficult to carry out, such as bridges, traffic barriers, large machinery, metal doors and windows, etc.

Description

technical field [0001] The invention relates to a coating, in particular to a stable water-based rust coating. Background technique [0002] 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. Some of the stable water-based rust coatings currently on the market have weak adhesion, and are easy to fall off after long-term use, and cannot achieve effective decoration and protection effects. Contents of the invention [0003] The invention provides a stable water-based paint with rust. [0004] The present invention is achieved through the following technical solutions: [0005] Stable water-based rust paint, the raw materials and parts by weight of the paint are as follows: [0006] 3...
