Problems solved by technology

In order to obtain a good anti-corrosion effect, it is usually necessary to carry out strict surface treatment on the substrate before painting, and it is generally necessary to use a primer, a primer, a topcoat, or a primer and a topcoat. The amount of paint is large, the process is complicated, and the interval time is long
In addition, most of the traditional coatings add toxic pigments, organic solvents, etc., which not only cause damage to the environment, but also pose a threat to personal safety.

Abstract

The invention discloses an energy-saving efficiency increasing primer-topcoat anti-corrosion coating and a preparation method thereof. The anti-corrosion coating comprises epoxy resin, waterborne polyurethane resin, glass flakes, environment friendly pigments and fillers, silane coupling agents, thixotropic agents, activated diluents, curing agents, auxiliaries and solvents. The preparation methodincludes the steps: (1) glass flake pretreatment; (2) raw material mixing. By a reasonable formula design and the preparation method, the prepared anti-corrosion coating has excellent anti-corrosioneffects and long anti-corrosion effects, the anti-corrosion performance of the coating is effectively enhanced, the primer-topcoat coating can be directly sprayed and cured at low temperature, has rust removal functions and has the advantages of energy conservation, emission reduction, safety and environmental protection, the construction process is effectively simplified, industrial three industrial wastes are decreased, and the market prospect is wide.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to an energy-saving and efficiency-enhancing bottom-surface-integrated anti-corrosion coating and a preparation method thereof. Background technique [0002] Corrosion greatly shortens the service life of steel and other equipment, causing a lot of waste of manpower and financial resources. For example, the direct and indirect economic losses caused by the shutdown and maintenance of large power stations due to equipment corrosion are very alarming; the corrosion of chemical equipment leads to frequent equipment accidents , the service life is reduced, and the loss caused is also great. Therefore, it is very necessary to develop anti-corrosion coatings with excellent performance to reduce or delay the corrosion of equipment and prolong its service life. [0003] As a simple and effective material protection and decoration method, paint coating can effectively improve the corr...
