Description

Technical Field

[0001] This utility model relates to a solid wood flooring, and more particularly to an environmentally friendly dual-moisture UV matte solid wood flooring. Background Technology

[0002] Solid wood flooring is highly favored for its natural texture and comfortable feel underfoot. Traditional solid wood flooring is often coated with high-gloss UV lacquer or PU lacquer, which, while offering some wear resistance, has the following drawbacks: 1) Light pollution: High-gloss surfaces are prone to glare under sunlight, which can cause visual fatigue with prolonged exposure; 2) Insufficient durability: The surface coating has limited hardness, making it easily scratched by sharp objects, and scratches are more noticeable on high-gloss surfaces, affecting its appearance.

[0003] In recent years, although matte flooring has emerged, its coating's wear and scratch resistance is generally poor, and existing matte flooring also has limited waterproof and moisture-proof properties, making it susceptible to moisture damage and warping. Therefore, there is an urgent need to develop a matte solid wood flooring that possesses both excellent wear and scratch resistance and good moisture resistance. Summary of the Invention

[0004] The purpose of this invention is to provide an environmentally friendly dual-moisture UV matte solid wood flooring. This invention has both good wear and scratch resistance and good moisture resistance.

[0005] The technical solution of this utility model is: an environmentally friendly dual-moisture UV matte solid wood flooring, comprising a solid wood substrate layer, the upper surface of which is sequentially provided with a UV penetrating primer layer, a UV matte varnish, and an aluminum oxide transparent wear-resistant varnish layer, and the lower surface of which is provided with a modified epoxy acrylate adhesive layer, a fiberglass mesh, and an aluminum foil PET film.

[0006] In the aforementioned environmentally friendly dual-moisture UV matte solid wood flooring, the solid wood substrate layer includes an intermediate honeycomb layer, and the upper and lower surfaces of the intermediate honeycomb layer are provided with solid wood base layers; the intermediate honeycomb layer includes a core layer, and a set of hexagonal honeycomb openings are provided on the core layer, and the hexagonal honeycomb openings are filled with a sound-absorbing material layer and a PCM phase change material layer from bottom to top.

[0007] In the aforementioned environmentally friendly dual-moisture UV matte solid wood flooring, the mounting surface of the solid wood substrate layer is provided with a sound-absorbing pad.

[0008] Compared with existing technologies, this invention significantly improves the hardness and scratch resistance of the topcoat layer by applying a UV penetrating primer layer (which seals the substrate, increases its surface strength, and prevents the topcoat from seeping under), a UV matte varnish, and an aluminum oxide transparent wear-resistant varnish layer to the upper surface of the solid wood substrate. Furthermore, by sequentially applying a modified epoxy acrylate adhesive layer, a fiberglass mesh, and an aluminum foil PET film to the lower surface of the solid wood substrate, a three-layer composite structure forms an indestructible moisture barrier, preventing moisture intrusion and warping of the flooring. In summary, this invention offers both excellent wear and scratch resistance and superior moisture resistance. Attached Figure Description

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0012] Example: Environmentally friendly dual-moisture UV matte solid wood flooring, composed of the following... Figure 1 As shown, it includes a solid wood substrate layer 1, and the upper surface of the solid wood substrate layer 1 is sequentially provided with a UV penetrating primer layer 2, a UV matte varnish 3, and an aluminum oxide transparent wear-resistant varnish layer 4. The lower surface of the solid wood substrate layer 1 is provided with a modified epoxy acrylate adhesive layer 5, a fiberglass mesh 6, and an aluminum foil PET film 7.

[0013] The solid wood substrate layer 1 includes an intermediate honeycomb layer 11, with solid wood base layers 12 on both the upper and lower surfaces of the intermediate honeycomb layer 11. The intermediate honeycomb layer 11 includes a core layer 111, with a set of hexagonal honeycomb openings 112 on the core layer 111. The hexagonal honeycomb openings 112 are filled from bottom to top with a sound-absorbing material layer 113 and a PCM phase change material layer 114. The solid wood substrate layer is composed of the intermediate honeycomb layer and the solid wood base layers. The hexagonal honeycomb openings of the intermediate honeycomb layer are filled with sound-absorbing material and PCM phase change material layers. On the one hand, this effectively improves sound insulation performance by absorbing and dissipating sound waves and vibration energy, giving the floor excellent sound insulation performance and sound absorption effect, reducing noise transmission between floors. On the other hand, it also has a certain temperature regulation function.

[0014] Furthermore, the hexagonal honeycomb structure can significantly improve bending, compressive, and shear strength, solving the anisotropy problem of solid wood and greatly enhancing dimensional stability. The mounting surface of the solid wood substrate layer 1 is provided with a sound-absorbing pad 8. The sound-absorbing pad can further improve the sound absorption effect.

[0015] UV penetrating primer is an existing product on the market. You can choose LY0003 (UV roller coating transparent penetrating primer) produced by Chengdu Liyuan Polymer Materials Co., Ltd. UV matte paint is a water-based UV matte topcoat containing nano-silica.

[0016] The sound-absorbing material layer uses TPE damping material.

[0017] The solid wood substrate layer can be made of high-quality woods such as oak, maple, and walnut. A UV penetrating primer is first applied to its surface using a roller coating method. This primer fully penetrates into the pores of the wood under vacuum impregnation or normal pressure conditions, and is then cured by a UV LED light source to form a penetrating primer layer. This layer serves to seal the substrate, increase its surface strength, and prevent the topcoat from seeping under.

[0018] Subsequently, a UV matte varnish (which can be a water-based UV polyurethane-acrylic composite topcoat containing nano-silica, in which 5% of the solid content of 30nm nano-silica microspheres have been uniformly added using a high-speed dispersion device) is applied through multiple precision roller coatings on the primer layer. After coating, it is cured under ultraviolet light to form a UV matte topcoat layer. The surface gloss of this topcoat layer is controlled at around 20 GU, with a smooth and delicate feel and a high-end matte appearance.

[0019] The surface beneath the solid wood substrate is treated as follows: a low-viscosity modified epoxy acrylate adhesive is roller-coated, followed by the application of fiberglass mesh and aluminum foil PET film. Roller pressing allows the modified epoxy acrylate adhesive to partially penetrate the wood, forming an anchoring reinforcement layer. This is then instantly cured by strong ultraviolet light, creating a robust, rigid, and moisture-proof bottom layer. The modified epoxy acrylate adhesive layer bonds firmly to the substrate, the fiberglass mesh layer provides excellent tensile strength and dimensional stability, and the absolute barrier layer completely isolates moisture from the ground. This three-layer composite structure forms an indestructible moisture barrier, preventing moisture from seeping in from beneath the floor.

[0020] The production process of the solid wood substrate layer: The hexagonal honeycomb openings of the middle honeycomb layer are filled with a sound-absorbing material layer and PCM phase change material. Then, the solid wood base layer with the sound-absorbing pads on the upper and lower surfaces is glued to the core layer.
