Description

Technical Field

[0001] This utility model relates to the field of flooring technology, and in particular to a flame-retardant multi-layer solid wood floor. Background Technology

[0002] Solid wood composite flooring boasts beautiful and natural textures and colors, a comfortable feel, and good heat insulation. However, wood itself is a flammable material, and solid wood composite flooring also has the same flammability defect. The widespread use of ordinary solid wood composite flooring in interior decoration poses a potential safety threat. In the event of a fire, it can easily cause casualties or huge economic and property losses.

[0003] Research revealed that existing wood flooring is typically flame-retardant as a whole. Under normal circumstances, the ignition point is the surface of the floor, so overall flame retardancy results in a certain degree of waste. Utility Model Content

[0004] The purpose of this utility model is to provide a flame-retardant multi-layer solid wood flooring, solving the problem of low flame retardancy in solid wood flooring in the prior art. The specific solution is as follows:

[0005] A flame-retardant multi-layer solid wood flooring includes a wood flooring body, the wood flooring body including a solid wood bottom layer located at the bottom, a multi-layer board layer disposed on top of the solid wood bottom layer, a solid wood top layer disposed on top of the multi-layer board layer, and a flame-retardant board layer disposed on top of the solid wood top layer.

[0006] The floor body has a main tenon on a first side and a main mortise on a second side; the main tenon and the main mortise fit together.

[0007] A secondary tenon is provided directly above the main tenon, and a secondary tenon is provided directly above the main tenon.

[0008] The secondary tenon groove matches the secondary tenon head;

[0009] A flame-retardant microparticle layer is provided on the top of the flame-retardant plate layer;

[0010] The outer surface of the flame-retardant microparticle layer is provided with a flame-retardant coating layer;

[0011] The flame-retardant coating extends to the side of the secondary tenon and above the secondary tenon at both ends to cover the top.

[0012] A flame-retardant clear coat is provided on top of the flame-retardant coating layer.

[0013] Optionally, the flame-retardant microparticle layer is made of aluminum oxide powder.

[0014] Optionally, the alumina powder has a mesh size of 800-1000 mesh.

[0015] Optionally, the flame-retardant veneer is made by soaking the veneer in a solution containing a flame retardant.

[0016] The beneficial effects of this utility model are as follows: covering the top with a flame-retardant paint layer, a flame-retardant particle layer, and a flame-retardant board layer can protect the top of the multi-layer solid wood flooring, preventing flames from penetrating the floor body, without the need for overall fireproofing.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figures 1 to 2 A flame-retardant multi-layer solid wood flooring includes a wood flooring body, the wood flooring body including a solid wood bottom layer 1 located at the bottom, a multi-layer board layer 2 disposed on top of the solid wood bottom layer 1, a solid wood top layer 3 disposed on top of the multi-layer board layer 2, and a flame-retardant board layer 4 disposed on top of the solid wood top layer 3.

[0031] Flame-retardant layer 4 is made by soaking the veneer in a solution containing flame retardant. The flame retardant can be any existing inorganic flame retardant, any organic flame retardant or composite flame retardant, and various commercially available flame retardant products can be used.

[0032] The floor body has a main tenon a on a first side and a main tenon c on a second side; the main tenon a and the main tenon c fit together, for reference. Figure 3 ;

[0033] A secondary tenon groove b is provided directly above the main tenon a, and a secondary tenon d is provided directly above the main tenon groove c;

[0034] The secondary tenon groove b matches the secondary tenon d, for reference. Figure 3 ;

[0035] The flame-retardant board layer 4 is provided with a flame-retardant microparticle layer 5. The flame-retardant microparticle 5 is aluminum oxide powder with a mesh size of 800-1000. The aluminum oxide powder is coated on the top of the flame-retardant board layer 4 with adhesive, wherein the adhesive is flame-retardant adhesive.

[0036] The outer surface of the flame-retardant microparticle layer 5 is provided with a flame-retardant topcoat layer 6, which is used to smooth the surface and perform flame-retardant treatment.

[0037] The flame-retardant surface coating layer 6 extends to the side of the secondary tenon groove b and above the secondary tenon d at both ends to wrap the top, thereby protecting the top of the multi-layer solid wood flooring and preventing flames from penetrating the floor body without requiring overall fireproofing.

[0038] The flame-retardant surface coating layer 6 is topped with a flame-retardant clear varnish layer 7. Both the flame-retardant surface coating layer 6 and the flame-retardant clear varnish layer 7 are made of environmentally friendly flame-retardant paint, which does not release toxic gases and improves the living environment.

[0039] This solution effectively protects the top of the wood flooring by setting a flame-retardant board layer 4, a flame-retardant microparticle layer 5, a flame-retardant surface coating layer 6, and a flame-retardant clear varnish layer 7, preventing flames from penetrating the flooring without requiring overall fireproofing.
