Description

Technical Field

[0001] This utility model belongs to the field of decoration materials technology, and relates to flooring, and more particularly to a multi-layered, multi-colored composite flooring. Background Technology

[0002] With the rapid development of society and the economy, people are paying increasing attention to flooring, a common decoration material. Nowadays, there are many types of flooring available, including ceramic tiles, PVC flooring, SPC flooring, engineered wood flooring, and laminate flooring. However, the structures of these flooring types are often relatively simple, and they have shortcomings in certain aspects. For example, ceramic tiles have a cold and hard surface and a poor feel underfoot; engineered wood flooring is prone to cracking and warping and is relatively expensive; and laminate flooring has difficulty controlling formaldehyde release and is susceptible to moisture damage at high temperatures.

[0003] In today's rapidly developing world, customized services have become a trend. The flooring available on the market often only offers consumers choices in terms of type, surface pattern, and texture, making it difficult to provide customized services for the structure and color of the base material. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to disclose a multi-layered, heterochromatic composite floor.

[0005] Technical solution

[0006] A multi-layer, multi-colored composite flooring includes a decorative surface layer, a composite substrate layer descending downwards, and a balancing layer on the back. A first adhesive layer and a second adhesive layer are provided between each layer of the composite substrate layer. The composite substrate layer is composed of three or more layers of ultra-thin moisture-proof fiberboard, PVC carbon crystal board, and inorganic straw board substrate. The assembly configuration from top to bottom includes: three layers: ultra-thin moisture-proof fiberboard + inorganic straw board / PVC carbon crystal board / plywood + ultra-thin moisture-proof fiberboard; four layers: ultra-thin moisture-proof fiberboard + any two combinations of inorganic straw board / PVC carbon crystal board / plywood + ultra-thin moisture-proof fiberboard; five layers: ultra-thin moisture-proof fiberboard + inorganic straw board + PVC carbon crystal board + plywood + ultra-thin moisture-proof fiberboard. The positions of the middle three layers can be arbitrarily adjusted. The color of each substrate layer is any one of red, black, natural wood color, blue, green, yellow, or brown.

[0007] In a preferred embodiment of this utility model, the decorative layer is melamine-impregnated decorative paper with a rich variety of patterns and textures on its surface, which is then hot-pressed onto the surface of the composite substrate layer. The surface properties meet the national standards for various finishes.

[0008] In a preferred embodiment of this utility model, the overall thickness of the composite substrate layer is 3-50 mm, preferably 30 mm, and the thickness of each substrate layer is 1-10 mm.

[0009] In a preferred embodiment of this utility model, the adhesive layer is a PUR hot melt adhesive curing layer. If the substrate layer has more than three layers, a third adhesive layer will be provided, and so on. The amount of adhesive applied to each layer is 40-80 g / m². 2 .

[0010] In a preferred embodiment of this utility model, the balancing layer is a balancing impregnated paper, and its color is any one of light brown, green, red, yellow, or black. Its function is to balance the internal moisture content of the board, release internal stress, and simultaneously provide moisture-proof and damp-proof functions, thereby reducing warping and deformation of the board.

[0011] Ultra-thin moisture-proof MDF, with the addition of 1-3% graphene material and 1-3% flame retardant, is superior to ordinary MDF in terms of dimensional stability, water absorption thickness expansion rate, formaldehyde release, and flame retardancy.

[0012] PVC carbon crystal board, scientifically known as polyvinyl chloride foam board, is a fireproof and lightweight decorative material widely used in interior partitions, roof insulation, air conditioning engineering packaging, etc. It has the characteristics of moisture resistance, weather resistance, impact resistance, heat insulation, acid and alkali corrosion resistance, and flame retardancy.

[0013] Inorganic straw board is made from straw (wheat straw, corn straw, rice straw, etc.) as raw material and inorganic materials such as magnesium oxide, magnesium sulfate, and magnesium chloride as fillers, and is prepared by cold pressing. Compared with traditional fiberboard, it has a lower formaldehyde emission, improved mechanical properties and waterproof performance. In addition, the waste utilization of straw and other materials is in line with the current concept of green environmental protection and sustainable development.

[0014] The multi-layered, multi-colored composite flooring disclosed in this utility model has tenons and grooves in both the length and width directions of the flooring, which facilitates locking and installation.

[0015] Beneficial effects

[0016] This utility model's composite substrate layer structure is composed of ultra-thin moisture-proof MDF, PVC carbon crystal board, and inorganic straw board in various colors. It possesses strong stability, a smooth surface, and is not prone to cracking or deformation, making it suitable for underfloor heating environments. The multi-layered, multi-colored composite structure effectively combines the advantages of various substrates, exhibiting superior dimensional stability, heat and moisture resistance, fire retardancy, and corrosion resistance compared to ordinary flooring, while significantly reducing costs and substantially increasing product added value.
