Problems solved by technology

However, in the existing anti-corrosion spraying process based on fluorocarbon coatings, the spraying effect of fluorocarbon coatings is not uniform, and the anti-corrosion time is short during use, and the phenomenon of shedding may occur, and the adsorption effect is not good at the same time, so that the coating and There are gaps between the metal substrates, resulting in corrosion, thus affecting the service life of the product

Abstract

The invention discloses a construction method of a water-based heavy-duty anti-corrosion fluorocarbon coating. The construction method comprises the following steps of removing oil stains on the surface of steel by using an alkaline degreasing agent, and washing with water after cleaning; removing rust scale by using acid pickling, removing the rust scale on the surface of the steel, and then conducting water washing; adding a phosphating agent for phosphating to form a phosphating film; adopting water-based heavy-duty anti-corrosion fluorocarbon paint as primer paint to be sprayed, being thespraying thickness 10-20 microns, and forming a primer coating through maintenance; using the water-based heavy-duty anti-corrosion fluorocarbon coating as a finish paint coating to be sprayed, beingthe spraying thickness 10-30 microns, and forming a finish paint protective coating through maintenance. According to the construction method of the water-based heavy-duty anti-corrosion fluorocarboncoating, the combination degree of the primer, the finish paint and the surface of the steel is high, the adhesive force of the coating is improved, the wear resistance, salt water resistance, weatherresistance and other properties of the coating are enhanced, the corrosion resistance of the steel is improved, meanwhile, the obtained coating is flat and uniform, the coating is lighter and thinner, the less paint can be used, cost is reduced, and construction is convenient.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a construction method of a water-based heavy-duty anti-corrosion fluorocarbon coating. Background technique [0002] With the development of the economy, the chemical industry, steel components, ships, power plants and other industries have increasingly urgent requirements for anti-corrosion of plates, pipes, pumps, etc., and the grades have been continuously improved. The anti-corrosion performance of materials has also put forward higher and higher requirements. Coatings with resin as the main film-forming substance are called fluorocarbon coatings. Such coatings have excellent chemical resistance, corrosion resistance, abrasion resistance, insulation, and stain resistance. The anti-corrosion spraying process refers to the Spray coating to achieve anti-corrosion effect and avoid items from being corroded. However, in the existing anti-corrosion spraying process...
