[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Please see Figure 1-Figure 3 The image shows a flame-retardant wood-plastic composite flooring panel, comprising a flooring body 1. To facilitate splicing two composite floorboards, a snap-lock connection design is adopted, which is more secure than the ordinary flat-lock connection. To achieve the snap-lock connection, a snap-lock groove 2 is provided on the side of the flooring body 1, and a snap-lock boss 3 is also provided on the flooring body 1 to cooperate with the snap-lock groove 2. To facilitate the snap-lock boss 3 being pressed into the snap-lock groove 2 during connection, two symmetrically arranged extrusion slots 4 are provided on the snap-lock boss 3. Thus, during extrusion installation, the snap-lock boss 3 deforms towards the extrusion slots 4 when compressed, achieving splicing installation.

[0033] The floor body 1 includes a protective layer 101, an upper waterproof layer 102, a flame retardant layer 103, a substrate layer 104, a lower waterproof layer 105, and a bottom layer 106.

[0034] A protective layer 101 is positioned on top of the upper waterproof layer 102. The protective layer 101 primarily provides excellent stain resistance and abrasion resistance for the composite flooring. To achieve this, the protective layer 101 comprises an anti-stain layer 101a, an abrasion-resistant layer 101b, and a decorative layer 101c. The abrasion-resistant layer 101b is positioned between the anti-stain layer 101a and the decorative layer 101c. The anti-stain layer 101a is the outermost layer, in contact with the external environment. It is coated with nano-silica material to provide basic stain resistance. By positioning the abrasion-resistant layer 101b between the anti-stain layer 101a and the decorative layer 101c, external abrasion factors will not directly affect the decorative layer 101c after the anti-stain layer 101a is damaged, thus ensuring the aesthetic appearance of the composite flooring. The abrasion-resistant layer 101b uses a fluorocarbon coating to provide abrasion resistance, thereby achieving the purpose of protecting the protective layer 101c.

[0035] The primary combustion zone in composite flooring is the substrate layer. Because composite flooring uses wood-plastic composite (WPC) substrates, without flame-retardant treatment, the WPC material is highly flammable during combustion. Therefore, a flame-retardant layer 103 is applied to the top of the substrate layer 104. This flame-retardant layer 103 is coated with a melamine metal oxide flame retardant. The melamine metal oxide flame retardant absorbs a large amount of heat and releases water vapor at high temperatures, thereby lowering the combustion temperature and inhibiting the release of flammable gases. Due to its low-smoke and non-toxic properties, it is an excellent environmentally friendly flame retardant. Its application in composite flooring not only provides basic flame-retardant properties but also prevents the production of large amounts of toxic substances during combustion.

[0036] To prevent the flame retardant layer 103 and the substrate layer 104 from being affected by water immersion in special environments, the flame retardant layer 103 is disposed between the upper waterproof layer 102 and the substrate layer 104.

[0037] The upper waterproof layer 102 consists of two layers: an aluminum foil layer 102a that provides physical waterproofing, and a reinforcing layer 102b that enhances the torsional strength of the entire composite flooring. The reinforcing layer 102b is made of polyphenylene sulfide material, which not only increases the strength of the entire composite flooring, but also prevents water stains from directly corroding the base layer 104 when the layers above the reinforcing layer 102b are damaged, thus further improving the service life of the composite flooring.

[0038] To prevent ground moisture from eroding the substrate layer 104, a lower waterproof layer 105 is provided, which is located between the substrate layer 104 and the bottom layer 106.

[0039] The lower waterproof layer 105 consists of two layers: a sound-absorbing layer 105a and a water-resistant layer 105b. The water-resistant layer 105b provides physical waterproofing for the aluminum foil. The sound-absorbing layer 105a is made of polyurethane sound-absorbing board, effectively preventing noise transmission and improving the overall sound insulation of the composite flooring. The water-resistant layer 105b is placed outside the sound-absorbing layer 105a, effectively providing waterproofing for both the sound-absorbing layer 105b and the substrate layer 104, preventing moisture from the composite flooring installation surface from entering the substrate layer 104. To prevent the water-resistant layer 105b from directly contacting the installation surface, a bottom layer 106 is placed beneath the water-resistant layer 105b. The bottom layer 106 is made of melamine resin.
