Composite floor produced by using poplar single plate and density plate

The utility model relates to a high-grade composite floor made from single poplar plates and density plates. The utility model is structured in that the upper surface and the lower surface of a high-density fiber plate are respectively provided with a multi-layer single plate, the surface of the multi-layer single plate on the upper surface of the high-density fiber plate is provided with an ornamental surface decorating veneer, the lower surface of the multi-layer single plate on the lower surface of the high-density fiber plate and the upper surface of the ornamental surface decorating veneer are both sanded finely and are respectively decorated by a paint coat made from UV photocurable coatings, and the periphery of the high-density fiber plate is provided with tongues and grooves. The ornamental surface decorating veneer, the multi-layer single plates, and the high-density fiber plate are integrated by lamination and gluing pressure. Because multi-layer rotary cut single poplar plates are used as backing material, density polar plates are used as core material, and the surface of the utility model adopts veneer sliced from high-grade hard wood, the original defects of softness and roughness on the polar are changed. Therefore, the appearance and the size of the utility model are stable, the density, strength, hardness, durability, water resistance, high temperature deformation resistance, etc. are all superior to solid wood. Because of the veneer and the prefabricated paint on the surface, the utility model has the advantages of beautiful patterns and colors, strong integrity and convenient laying.
