Description

Technical Field

[0001] The utility model relates to the technical field of galvanized plates, in particular to a highly wear-resistant galvanized plate. Background Art

[0002] Galvanized steel sheet is a welded steel sheet with hot-dip or electroplated zinc layer on the surface, which is generally widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industry, etc. However, due to the large production volume and tight construction period in the actual production process, it is easy to cause friction and collision during storage and transportation, and even in a serious corrosive environment, which will cause the zinc coating to be damaged and lose its protective significance.

[0003] A highly wear-resistant galvanized steel plate with a publication number of CN215704713U comprises a steel plate base, a galvanized layer is arranged on the outer surface of the steel plate base, a passivation layer is arranged on the top of the galvanized layer, a first slot and a second slot are provided on the top of the galvanized layer, the first slot and the second slot are a plurality of interconnected groups, a zinc phosphate chemical conversion film is arranged on the top of the passivation layer, a polyurethane prepolymer resin layer is arranged on the top of the zinc phosphate chemical conversion film, and a wear-resistant layer is arranged on the top of the polyurethane prepolymer resin layer. By arranging the galvanized layer, the passivation layer, the zinc phosphate chemical conversion film layer, and the polyurethane prepolymer resin layer, the corrosion resistance of the steel plate is improved; by arranging the first slot and the second slot, the galvanized layer can be prevented from aging and falling off; by arranging the wear-resistant layer, the wear resistance of the steel plate is improved.

[0004] The above technical solution is difficult to solve the adhesion effect of the galvanized layer of the steel plate when it is actually used. When used for a long time, the galvanized layer is prone to fall off due to wear or aging, which affects the long-term use of the galvanized sheet.

[0005] Therefore, it is necessary to invent a high wear-resistant galvanized sheet to solve the above problems. Utility Model Content
