Description
Technical Field

Background
The epoxy resin coating is prepared by using epoxy resin as a base material, can play roles in corrosion prevention, protection, decoration and the like, and is widely applied to the fields of petroleum, chemical engineering, pipelines, buildings, ocean engineering and the like. The solvent type epoxy resin coating mainly has the defects of high VOC content, great pollution and waste, unsatisfactory safety and the like. The solvent-free epoxy resin coating has the outstanding advantages of realizing zero VOC emission, and meanwhile, compared with powder coatings, the solvent-free epoxy resin coating has more convenient construction and better workpiece adaptability, and is an important development direction of environment-friendly coating products. In the anti-corrosion construction scheme of the steel pipe pile or the buried pipeline, the solvent-free epoxy resin coating is often the first choice of anti-corrosion coating. The solvent-free epoxy resin coating has the other advantage that thicker coating thickness can be realized, the thickness of the coating can reach 300-500 mu m in one construction under general conditions, and the quality of the coating film can be ensured. The common epoxy resin coating is generally applied in one step, the dry film thickness is 60-100 mu m, and the thick paste product can reach about 150 mu m. Obviously, the solvent-free epoxy resin coating has better construction efficiency, and can meet the required film thickness requirement only by one construction under most conditions.

Although the traditional solvent-free epoxy resin coating has the advantages of no VOC emission, environmental protection, safety and the like, the typical defects are that the brittleness and the wear resistance are not ideal. These disadvantages limit the use of conventional solventless epoxy coatings in certain devices or components that need to withstand impact.
