Abstract

The invention discloses a long-acting waterborne over-rust corrosion protective coating. The long-acting waterborne over-rust corrosion protective coating comprises the following components by weight: 20-35 parts of modified high-performance anti-corrosive emulsion, 10-20 parts of aluminum triphosphate, 6-12 parts of zinc phosphate, 0.1-0.8 part of defoamer, 2-4 parts of wetting dispersant, 10-20 parts of organic chelating agent dispersing agent, 37-45 parts of pigment and filler, 0.1-0.2 part of mildew preventive, 0.2-0.3 part of anti-flash-rust agent, and 7-12 parts of deionized water. The invention provides the long-acting waterborne over-rust corrosion protective coating, the rust is converted into a mode of a dense protective film within a short period of time by improving the crosslinking density and the strength of a film and promoting the rapid dispersing and chelating of the rust, so that the durability, the salt spray resistance and the adhesive force of the coating are improved obviously.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coating, in particular to a long-acting water-based anti-corrosion coating with rust and its preparation method and application. Background technique [0002] Steel structure plays a vital role in the development of modern industry. Corrosion of steel structure causes huge economic losses. The simplest and most effective way to protect it is to apply anti-corrosion coatings. The protection of paint is time-sensitive, and it needs to be repainted after it expires. When repainting, it is necessary to perform sandblasting, shot blasting and other operations on the steel structure to completely remove rust. The process is cumbersome and the cost is high; The problem is that sandblasting and shot blasting cannot be carried out, and it is difficult to perform adequate rust removal, which requires the use of low surface treatment rust coatings. The low surface treatment rust coating can be direct...
