Description

Technical Field

[0001] This utility model relates to a solid wood composite floor, and more particularly to a carbonized flame-retardant solid wood composite floor. Background Technology

[0002] Engineered wood flooring is made by cross-lamining different types of wood, which to some extent overcomes the drawbacks of solid wood flooring such as expansion and contraction due to moisture. It has a low rate of expansion and contraction, good dimensional stability, and retains the natural wood grain and comfortable feel of solid wood flooring. It combines the stability of laminate flooring with the aesthetics of solid wood flooring, and also has environmental advantages.

[0003] However, traditional engineered wood flooring is a flammable material, posing a fire hazard. To improve its flame-retardant properties, most flame-retardant flooring on the market currently uses fire-retardant coatings on the surface of the boards or impregnation of the substrate with flame retardants. However, the flame-retardant coating on engineered wood flooring produced by this method is easily worn away, affecting its flame-retardant performance and resulting in a short duration. Therefore, existing technologies suffer from the problem of easily damaged surface flame-retardant coatings. Summary of the Invention

[0004] The purpose of this invention is to provide a carbonized flame-retardant solid wood composite flooring. This invention effectively improves the duration of its flame-retardant properties.

[0005] The technical solution of this utility model is: carbonized flame-retardant solid wood composite flooring, including a carbonized flame-retardant solid wood surface layer, a flame-retardant core layer on the lower surface of the carbonized flame-retardant solid wood surface layer, and a flame-retardant balancing bottom layer on the lower surface of the flame-retardant core layer; the upper and lower surfaces of the flame-retardant core layer are provided with grooves, the grooves are filled with flame-retardant material, and the lower surface of the carbonized flame-retardant solid wood surface layer and the upper surface of the flame-retardant balancing bottom layer are provided with flame-retardant heat-insulating pads, and the surface of the flame-retardant heat-insulating pads is provided with matching flame-retardant protrusions.

[0006] In the aforementioned carbonized flame-retardant solid wood composite flooring, the flame-retardant balance bottom layer includes a magnesium-based flame-retardant board, the bottom surface of which is provided with a set of hexagonal grooves, and flame-retardant sound-absorbing and vibration-damping blocks are provided in the hexagonal grooves.

[0007] In the aforementioned carbonized flame-retardant solid wood composite flooring, a flame-retardant and moisture-proof pad is also provided below the magnesium-based flame-retardant board.

[0008] In the aforementioned carbonized flame-retardant solid wood composite flooring, the surface of the carbonized flame-retardant solid wood layer is also provided with a flame-retardant UV paint layer and a transparent wear-resistant coating.

[0009] Compared with existing technologies, this invention consists of a carbonized flame-retardant solid wood surface layer, a flame-retardant core layer, and a flame-retardant balancing layer, with a flame-retardant and heat-insulating pad placed between adjacent layers. The flame-retardant protrusions of the heat-insulating pad cooperate with the grooves of the flame-retardant core layer, thereby effectively improving the flame-retardant performance of the solid wood composite flooring. In summary, this invention effectively improves the duration of flame-retardant performance. Attached Figure Description

[0013] Example. Carbonized flame-retardant solid wood composite flooring, composed as follows: Figure 1 As shown, it includes a carbonized flame-retardant solid wood surface layer 1, a flame-retardant core layer 2 on the lower surface of the carbonized flame-retardant solid wood surface layer 1, and a flame-retardant balancing bottom layer 3 on the lower surface of the flame-retardant core layer 2; the upper and lower surfaces of the flame-retardant core layer 2 are provided with grooves 4, the grooves 4 are filled with flame-retardant material 5, the lower surface of the carbonized flame-retardant solid wood surface layer 1 and the upper surface of the flame-retardant balancing bottom layer 3 are provided with flame-retardant heat insulation pads 6, and the surface of the flame-retardant heat insulation pads 6 is provided with matching flame-retardant protrusions 7.

[0014] The flame-retardant balance bottom layer 3 includes a magnesium-based flame-retardant plate 31. The bottom surface of the magnesium-based flame-retardant plate 31 is provided with a set of hexagonal grooves 32, and flame-retardant sound-absorbing and vibration-damping blocks 33 are provided in the hexagonal grooves 32.

[0018] The flame-retardant core layer includes a solid wood core layer, and the upper and lower surfaces of the solid wood core layer are provided with a flame-retardant coating.

[0019] The carbonized flame-retardant solid wood surface layer 1 uses oak veneer, which is first carbonized at 200℃ in a low-oxygen environment for 24 hours. Alternatively, the carbonized flame-retardant solid wood material can be placed in a high-pressure tank, vacuumed to -0.095MPa, and maintained for 30 minutes. An environmentally friendly phosphorus-nitrogen water-based flame retardant can then be injected, pressurized to 1.2MPa, and maintained for 2 hours to allow the flame retardant to fully penetrate. Finally, it is dried until the moisture content meets the standard. Then, a flame-retardant UV lacquer layer and a transparent wear-resistant coating are applied by roller.

[0020] Flame-retardant core layer 2: First, grooves are made on the upper and lower surfaces of the solid wood core layer, then a flame-retardant coating is rolled onto the surface of the solid wood core layer; finally, flame-retardant material is filled into the grooves to a height of half.

A hexagonal groove is set on the bottom surface of the magnesium-based flame-retardant board, and flame-retardant sound-absorbing and vibration-damping blocks are set. Finally, a flame-retardant and moisture-proof pad is attached to the bottom surface.

[0022] Flame-retardant polyurethane adhesive is applied between the carbonized flame-retardant solid wood surface layer, the carbonized flame-retardant solid wood surface layer, and the flame-retardant core layer.

[0023] The three layers are coated with flame-retardant polyurethane adhesive, and a flame-retardant heat insulation pad is placed between adjacent layers. The carbonized flame-retardant solid wood surface layer, flame-retardant heat insulation pad, flame-retardant core layer, flame-retardant heat insulation pad and flame-retardant balance layer are hot-pressed and composite molded using a hot press.
