Description

Technical Field

[0001] This utility model relates to the field of SPC flooring technology, specifically to an improved multi-layer co-extruded SPC flooring. Background Technology

[0002] Flooring is an important part of interior decoration. It not only provides practical support but also matches the overall design style of the room. Among them, multi-layer co-extruded SPC flooring is a composite flooring manufactured through multi-layer co-extrusion technology. It combines the stability of SPC material with the advantages of multiple functional layers.

[0003] However, traditional SPC flooring still has some shortcomings in its use: In terms of wear resistance, it also needs improvement. After long-term use, wear marks are easily seen on the surface of the floor, affecting the normal use and appearance of the floor. In addition, its moisture resistance is not ideal. In humid environments, the floor is prone to absorbing moisture, causing it to swell and warp.

[0004] The flooring is not very protective and has weak impact resistance. When subjected to a large external impact, the flooring is prone to internal structural displacement, resulting in insufficient stability between the various structures and reducing its practicality. Utility Model Content

[0005] The purpose of this invention is to provide an improved multi-layer co-extruded SPC flooring to address the issues raised in the background art, such as the need to improve wear resistance, the tendency for wear marks to appear on the floor surface after prolonged use, affecting the normal use and aesthetics of the flooring, insufficient moisture resistance (causing the flooring to absorb moisture and swell and warp in humid environments), low protective properties, weak impact resistance (causing internal structural displacement when subjected to significant external impacts), and insufficient stability between different structures, thus reducing practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An improved multilayer co-extruded SPC flooring includes a reinforcing shell, within which a flooring body is disposed. The flooring body is composed of a base layer, a decorative layer, a wear-resistant layer, and a protective layer. The bottom of the base layer is bonded to the decorative layer, the bottom of the decorative layer is bonded to the wear-resistant layer, and the bottom of the wear-resistant layer is bonded to the protective layer. The base layer is made of a mixture of polyvinyl chloride and lime powder. The decorative layer is made of printed colored film. The wear-resistant layer is made of wear-resistant sand. The protective layer is made of UV-resistant material. Side panels are provided on the sides of the flooring body.

[0007] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the side of the side guard plate, a connecting groove is provided on the side of the floor body, the connecting plate extends into the connecting groove, the connecting plate and the connecting groove are bonded together with glue, and a stabilizing plate is provided on the outer surface of the floor body. The stabilizing plate is U-shaped, and the end of the stabilizing plate extends to the outer surface of the side guard plate.

[0008] As a preferred embodiment of this utility model, a reinforcing rod is provided on the outer surface of the side of the stabilizing plate. The reinforcing rod passes through the stabilizing plate and extends into the floor body. The reinforcing rod is threadedly connected to the stabilizing plate.

[0009] As a preferred embodiment of this utility model, the surface of the stabilizing plate is provided with a receiving groove, a positioning plate is provided in the receiving groove, a fixing rod is provided on the outer surface of the positioning plate, and the surface of the side guard plate is provided with a positioning groove.

[0010] As a preferred embodiment of this utility model, the fixing rod passes through the positioning plate and the stabilizing plate and extends into the positioning groove, and the fixing rod is threadedly connected to the positioning plate.

[0011] As a preferred embodiment of this utility model, the stabilizing plate and the reinforcing shell are fixedly connected, the reinforcing shell is made of stainless steel, and the stabilizing plate is made of the same material as the base layer.

[0012] As a preferred embodiment of this utility model, two side guards are provided, and the two side guards are respectively located at both ends of the floor body.

[0013] As a preferred embodiment of this utility model, four reinforcing rods are provided, all four reinforcing rods are the same size, and all four reinforcing rods are made of stainless steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting up a floor body, a base layer, a decorative layer, a wear-resistant layer, a protective layer, a reinforcing shell, and side guards, the floor body serves as the overall supporting structure. The base layer is made of polyvinyl chloride and lime powder, ensuring that the floor is not easily deformed during long-term use. The decorative layer enhances the aesthetics of the floor. The wear-resistant layer is made of wear-resistant sand, which effectively enhances the wear resistance of the floor. The UV material of the protective layer has the characteristics of being waterproof and deformation-resistant. The combination of the reinforcing shell and side guards further protects the floor, reduces damage to the sides, and extends the service life of the floor.

[0015] 2. In this utility model, by using a combination of a stabilizing plate, a positioning plate, a positioning groove, a fixing rod, and a reinforcing rod, the stabilizing plate is located at the bottom of the floor body, providing a stable support foundation for the floor. The end of the stabilizing plate is located at the bottom of the side guard plate.
