Rapid coating paint for anti-corrosion operation as well as use method and application of rapid coating paint

Abstract

The invention relates to the field of anti-corrosion paint, in particular to rapid coating paint for anti-corrosion operation as well as use a method and application of rapid coating paint. The rapid coating paint comprises a first component and a second component, the first component is prepared from phosphate containing a single phosphorus-oxygen tetrahedron, metal powder, epoxy resin and a curing agent, and the second component comprises acrylic polyurethane. The zinc powder content of the rapid coating paint is up to 80% or above, the rapid coating paint has an excellent cathode protection effect, can maintain long-acting corrosion resistance for 10-15 years on steel members, can realize coating with rust, can realize high bonding strength and high corrosion resistance without removing metal rust, is suitable for surface corrosion resistance of rusted steel materials of railways, power plants, chemical engineering, ships and the like, has an excellent corrosion resistance effect, and can be widely applied to the field of corrosion prevention of steel products. Good application prospects are realized.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a quick-coating coating for anti-corrosion operations and its use method and application. Background technique [0002] Metals are easily affected by the environment to undergo chemical or electrochemical reactions and cause damage to their own quality. This phenomenon is called metal corrosion. Almost all metal products will have some forms of corrosion in a certain environment, and the corrosion phenomenon will be significantly different when the use environment and time are different. Especially in coastal areas, the salinity and humidity in the atmosphere are extremely high, and there are many polluting industries, such as: steel, petrochemical, thermal power generation, etc., and the number of cars has increased significantly, and the exhaust gas is full of corrosive sulfur in the air. These are the main causes of metal corrosion. Metal corrosion will cause huge equi...

AI Technical Summary

Problems solved by technology

[0004] At present, the anti-corrosion coatings on the market have a short anti-corrosion life, especially when used in coastal cities and outdoor environments with severe weather, the anti-corrosion ability will weaken with the increase of the service life. In addition, ordinary anti-corrosion coatings have low viscosity and are easy to fall off When most of the anti-corrosion coatings are applied to the corroded metal surface, the corrosion layer needs to be removed before the coating can be covered, which affects the construction conditions and project progress.
