Description

Technical Field

[0001] The utility model relates to the technical field of floors, in particular to a composite stone-plastic floor. Background Art

[0002] Currently, most floors on the market are solid wood floors. However, to ensure strength, solid wood floors are generally thicker, with a thickness of more than 12mm. The shipping volume per cabinet is small and the price is expensive. In addition, pure solid wood floors are easily corroded by water, mold, and insects.

[0003] Currently, PVC flooring on the market is typically painted on the exposed side for waterproofing, but lacks a protective layer on the side that contacts the ground. This allows liquid to easily accumulate at the bottom of the floor, leading to mold growth. Because the bottom of the floor is usually not cleaned, the mold can easily spread into the air, polluting the air and affecting health, while also producing unpleasant odors that can cause discomfort. Furthermore, as a chlorine-containing material, PVC decomposes when exposed to light and heat, producing irritating gases such as hydrogen chloride and chlorine, which can affect human health.

[0023] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0024] Example 1

[0025] This embodiment provides a composite stone-plastic floor, which includes a veneer layer 200, a base layer 300, and a wood balancing layer 400 arranged in sequence. Adhesive layers are provided on both sides of the base layer 300. The veneer layer 200 is bonded to the base layer 300 via the adhesive layers. A protective layer 100 is provided on the surfaces of the veneer layer 200 and the wood balancing layer 400.

[0026] Please refer to Figure 1 As shown, in this embodiment, the composite stone-plastic flooring is constructed by applying a veneer layer 200 to the upper surface of a base layer 300. The natural wood grain of the veneer layer 200 mimics that of a solid wood floor, enhancing the aesthetics of the composite stone-plastic flooring. By applying the veneer layer 200 to the base layer 300, the overall thickness and center beam of the board can be reduced while maintaining aesthetics, thus preventing mold and deformation in solid wood floors. A wood balancing layer 400 is provided at the lower end of the base layer 300. This balancing layer isolates moisture, balances the tensile forces of the base layer 300, prevents deformation, and increases the lifespan of the flooring. A protective layer 100 is applied to the upper surface of the veneer layer 200 and the wood balancing layer. This protective layer 100 provides waterproof and insect repellent properties. Formed at both the upper and lower ends of the flooring, the protective layer 100 prevents liquids from penetrating the base layer 300 and liquids from the bottom from entering the wood balancing layer 400, preventing mold growth in the wood balancing layer 400 and ensuring the safety of the flooring.

[0027] Optionally, in some implementations of this embodiment, the thickness of the veneer layer 200 is 0.5-1.0 mm.

[0028] In this embodiment, the veneer layer 200 primarily serves to coat the surface of the base material with natural wood grain. A thickness of less than 1 mm reduces the overall thickness and weight of the flooring. Furthermore, a thinner veneer layer 200 facilitates adhesion of the veneer layer 200 to the base material 300, preventing separation from the base material 300. When the protective layer 100 is applied, the applied liquid is more likely to fully penetrate the veneer layer 200, forming a single layer with the veneer layer 200 and enhancing the waterproofing effect of the veneer layer 200. It is understood that the fiber structure of the veneer layer 200 contains numerous gaps, which facilitate liquid penetration when the protective layer 100 is applied. When the veneer layer 200 is less than 1 mm thick, the applied liquid can fully penetrate the entire veneer layer 200, forming a single layer with the veneer layer 200, ensuring the waterproofing and scratch resistance of the veneer layer 200 and extending the life of the flooring. The thickness of the veneer layer 200 can be adjusted based on the type of wood and actual production needs. If the veneer layer 200 is less than 0.5 mm thick, its light transmittance increases, potentially revealing the color and texture of the base layer 300 and affecting the aesthetics of the entire floor. Therefore, the veneer layer 200 should be no less than 0.5 mm thick.

[0029] Optionally, in some implementations of this embodiment, the thickness of the substrate layer 300 is 5-7 mm.

[0030] In this embodiment, the substrate layer 300 can be formed by extrusion of a composite material. A thickness of 5 mm or greater can meet the strength requirements during use. When the thickness of the substrate layer is less than 5 mm, its strength is low and it is difficult to meet the requirements of use. A thicker substrate layer 300 increases strength, but at the same time, the manufacturing cost and weight of the base plate increase. The increased weight also increases transportation costs. Therefore, the thickness of the substrate layer is preferably 5-7 mm.

[0031] Optionally, in some implementations of this embodiment, the substrate layer 300 is a PET substrate.

[0032] Polyethylene terephthalate sheet, also known as PET sheet or PETP sheet, stands for polyethylene terephthalate plastic in Chinese. Its main components are polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). Polyethylene terephthalate is also commonly known as polyester resin. PET sheet has high mechanical strength, stiffness, and hardness, excellent creep resistance, a low and stable coefficient of friction, excellent wear resistance, and excellent dimensional stability. It also exhibits excellent chemical stability, low water absorption, and resistance to weak acids and organic solvents, making it an ideal material for substrate layer 300. PET material also contains no chlorine. Compared to traditional PVC substrates, which decompose upon exposure to light and heat to produce irritating gases such as hydrogen chloride and chlorine, which can affect human health, PET sheet is a safer substrate.

[0033] Optionally, in some implementations of this embodiment, the protective layer 100 is a UV paint layer.

[0034] After UV paint is cured with strong ultraviolet light, its color stabilizes, effectively addressing the issues of fading and color shift in the floor. UV paint is also scratch-resistant, acid- and alkali-resistant, and non-deformable. In this embodiment, UV glue is applied to the surface of the veneer layer 200 by roller coating, and then the paint is cured using UV light, etc., to form a protective layer 100. During the roller coating process, the UV glue penetrates the entire veneer layer 200, forming a single unit with the veneer layer 200 and preventing delamination or shedding after curing. The protective layer 100 formed by the UV glue is scratch-resistant, acid- and alkali-resistant, protecting the veneer layer 200 and substrate layer 300 from scratches or corrosion. It also provides excellent waterproofing, preventing mold growth or deformation due to moisture in the floor. The aforementioned wood balancing layer 400 can be coated with UV paint and cured using the same roller coating method described above, forming a protective layer 100 on the surface of the wood balancing layer 400. Similarly, when the paint is applied, the UV paint will also penetrate into the entire wooden balancing layer 400, thereby improving the waterproof, mildew-proof and insect-proof effects of the wooden balancing layer 400, thereby improving the safety and service life of the composite stone-plastic floor.

[0035] Optionally, in some implementations of this embodiment, the thickness of the protective layer 100 is less than 0.02 mm.

[0036] In this embodiment, a protective layer 100 is formed on the surface of the veneer layer 200 or the wood balancing layer 400 by rolling on UV paint and performing light curing. During the rolling process, the UV paint penetrates the veneer layer 200 and the wood balancing layer 400, thereby improving the scratch resistance and acid and alkali resistance of the veneer layer 200. In this case, the veneer layer 200 itself can serve as the protective layer 100, and therefore the thickness of the protective layer 100 is less than 0.02 mm. By forming a thin film-like protective layer 100 on the surface of the veneer layer 200 and the wood balancing layer 400, in addition to improving the waterproof and scratch resistance of the veneer layer 200, the texture of the veneer layer 200 is maximized, thereby enhancing the aesthetics of the composite stone-plastic flooring. It can be understood that the purpose of applying the veneer layer 200 is to utilize the texture of the veneer layer 200 to mimic real wood flooring, thereby enhancing the aesthetics of the composite stone-plastic flooring. When the protective layer 100 is too thick, the wood texture of the veneer layer 200 will be obscured. Therefore, the thickness of the protective layer 100 is less than 0.02 mm.

[0037] Optionally, in some implementations of this embodiment, the adhesive layer is an acrylic glue layer.

[0038] In this embodiment, since conventional white glue for wood cannot adhere to PET materials, acrylic glue has good bonding ability and is very suitable for bonding the veneer layer 200 and the wooden balancing layer 400. During use, the good bonding ability of acrylic glue can prevent the veneer layer 200 and the wooden balancing layer 400 from falling off. Acrylic glue has a fast curing speed and can reach a high bonding strength within a few minutes. During production, the veneer layer 200 can be quickly bonded to the substrate layer 300, greatly improving production efficiency. Due to the excellent chemical corrosion resistance and high and low temperature resistance of acrylic glue, it has good stability in various environments, ensuring that the veneer layer 200 will not fall off during use. In combination with the protective layer 100, it can ensure the strength of the veneer layer 200, thereby improving the performance and service life of the entire composite stone plastic floor.

[0039] Optionally, in some implementations of this embodiment, rough bonding surfaces are provided on both sides of the substrate layer 300 , and the acrylic glue layer is coated on the bonding surfaces.

[0040] In this embodiment, the upper and lower surfaces of the substrate layer 300 are both configured as rough bonding surfaces. When applying acrylic glue, the rough bonding surfaces can improve the adhesion effect of the glue, ensure the firmness after pasting, and prevent the veneer layer 200 from falling off.

[0041] Optionally, in some implementations of this embodiment, a number of auxiliary bonding grooves may be provided at intervals on the upper and lower surfaces of the substrate layer 300. By providing grooves on the surface of the substrate layer 300, the surface area of the substrate layer 300 is increased, making it easier to apply more glue. After the glue solidifies, the adhesive layer is more easily engaged with the substrate layer 300, thereby improving the firmness after bonding.

[0042] Optionally, in some implementations of this embodiment, the wood balancing layer 400 has the same thickness as the veneer layer 200 .

[0043] In this embodiment, the thickness of the above-mentioned layer must be consistent with that of the solid wood veneer layer 200, and the material can be a substandard veneer of the same quality as the solid wood veneer layer 200. The wood balancing layer 400 is typically placed on the back of the substrate layer 300, so substandard veneer can be used. The wood balancing layer 400 has the same thickness as the veneer layer 200, balancing the tensile force of the substrate layer 300 and preventing warping and deformation of the substrate layer 300.

[0044] Optionally, in some implementations of this embodiment, an anti-slip component is provided on a side of the wooden balancing layer 400 away from the substrate layer 300 .

[0045] In this embodiment, an anti-slip component is provided on the lower surface of the wooden balancing layer 400. When installing the composite stone-plastic floor, this component provides a gripping effect, ensuring the stability of the stone-plastic floor. This component can be a number of anti-slip stripes. It is understood that currently, there are two main installation methods for flooring: direct laying flat or applying flooring adhesive to the back of the floor and then gluing the floor. When directly laying, the anti-slip component provides a non-slip effect, preventing the floor from shifting. When using flooring adhesive for installation, the anti-slip component also better adheres to the adhesive, improving the stability of the composite stone-plastic floor after installation.

[0046] Example 2

[0047] This embodiment provides a method for manufacturing a composite stone-plastic floor, the specific steps of which are as follows:

[0048] Step 1: Use PET material to make a base plate with a thickness of 5-7 mm;

[0049] Step 2: Use a sanding belt to sand the surface of the substrate to increase the surface roughness;

[0050] Step 3: Select acrylic pressure-sensitive adhesive and apply it to the upper and lower surfaces of the substrate board;

[0051] Step 4: Attach the veneer layer 200 and the wood balancing layer 400 to the upper and lower surfaces of the substrate, respectively, and cold-press them. This process is performed for 24 hours to ensure adequate contact between the glue, the veneer, and the substrate, ensuring a secure bond.

[0052] In summary, the embodiment of the present invention provides a composite stone plastic floor, which includes a veneer layer 200, a base material layer 300 and a wood balancing layer 400 arranged in sequence. Adhesive layers are provided on both sides of the base material layer 300. The veneer layer 200 is adhered to the base material layer 300 via the adhesive layers. The surfaces of the veneer layer 200 and the wood balancing layer 400 are both provided with a protective layer 100. The natural wood texture on the veneer layer 200 imitates the solid wood floor, thereby increasing the aesthetics of the composite stone plastic floor. By covering the veneer layer 200 with the base material layer 300, the thickness and center beam of the entire board can be reduced while ensuring the aesthetics, thereby avoiding the problem of mold and deformation of the solid wood floor. The lower end of the base material layer 300 is provided with a wood balancing layer 400. The wood balancing layer 400 serves to isolate moisture, balance the tissue tension of the base material layer 300, avoid deformation of the base material layer 300, and increase the service life of the floor. The upper surface of the veneer layer 200 and the wooden balance are covered with a protective layer 100. The protective layer 100 can play a waterproof and insect-proof role. The protective layer 100 is formed at the upper and lower ends of the floor respectively, which can prevent liquid on the floor from seeping into the base material layer 300 and prevent liquid at the bottom from entering the wooden balance layer 400, thereby preventing mold from growing in the wooden balance layer 400 and ensuring the safety of the floor.
