Description

Technical Field

[0001] This utility model relates to the field of composite flooring technology, specifically a wood-stone composite flooring. Background Technology

[0002] In the field of building decoration materials, flooring, as the surface layer of a building's floor or roof, is widely used in various indoor and outdoor spaces. Classified by structure, it encompasses solid wood flooring, engineered wood flooring, bamboo flooring, preservative-treated flooring, cork flooring, and multi-layer engineered wood flooring, among others. Classified by application, it includes various types such as residential, commercial, anti-static, outdoor, stage / dance, and track and field flooring. Among these, multi-layer engineered wood flooring, with its advantages of combining the texture of solid wood with good stability, has become a popular flooring product today.

[0003] Currently, traditional wood flooring structures have many shortcomings in practical applications. On the one hand, the processing precision requirements for the internal solid wood core layer are extremely high, ensuring sufficient surface flatness. Otherwise, bulging is easily generated during subsequent board processing, affecting not only the appearance quality of the flooring but also reducing its overall strength and stability, increasing scrap rate and production costs. On the other hand, the decorative layer is directly bonded to the solid wood core. Under heated conditions, due to the difference in their coefficients of thermal expansion, cracking and delamination are prone to occur, significantly shortening the flooring's lifespan and failing to meet users' needs for long-term stable use. Furthermore, as people's requirements for the performance of building decoration materials continue to increase, traditional wood flooring is gradually revealing its limitations in terms of wear resistance and service life, making it difficult to adapt to diverse application scenarios and usage needs. Utility Model Content

[0004] Therefore, to address the aforementioned shortcomings, this utility model provides a wood-stone composite flooring. This composite flooring has a wood-stone layer between the solid wood core layer and the decorative layer, which effectively solves the problems encountered when directly bonding the decorative layer and the solid wood core layer. Furthermore, the wood-stone layer eliminates the need to ensure sufficient flatness of the solid wood core layer during flooring processing; only the flatness of the wood-stone layer needs to be guaranteed. Since the wood-stone layer is formed under high temperature and pressure, the flatness of the processing is effectively ensured, thus reducing processing difficulty. Additionally, the wood-stone layer improves the flooring's wear and scratch resistance, thereby extending its service life.

[0005] This utility model is implemented as follows: a wood-stone composite floor is constructed, comprising a base layer, an intermediate layer and a surface layer arranged sequentially from bottom to top. The base layer is a wood veneer balancing layer, the intermediate layer includes a solid wood core layer, a wood-stone layer and a decorative layer, and the surface layer is a wear-resistant layer. The wood-stone layer is formed by high temperature and high pressure pressing.

[0006] Preferably, the materials of the log veneer balancing layer and the solid wood core layer are pine, poplar, or eucalyptus.

[0007] Preferably, the wear-resistant layer is made of aluminum oxide.

[0008] Preferably, the wood and stone layer and the adjacent layers are connected by a method of first cold pressing and then hot pressing.

[0009] Preferably, the flooring has the following dimensions: length 380-3200mm, width 80-1300mm, thickness 6-18mm, the original wood veneer balancing layer thickness 0.5mm, the solid wood core layer thickness 4.5-16.5mm, the wood-stone layer thickness 0.5-3.5mm, and the decorative layer and wear-resistant layer thickness 0.1mm each.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] Effectively solves the problem of cracking and delamination in the bonding layer: This composite flooring incorporates a wood-stone layer between the solid wood core layer and the decorative layer. This wood-stone layer acts as an intermediate transition structure, isolating the decorative layer from direct contact with the solid wood core layer. Due to the stable physicochemical properties of the wood-stone layer, it effectively buffers the stress caused by the difference in thermal expansion coefficients between the decorative layer and the solid wood core layer. This significantly reduces the risk of cracking and delamination of the decorative layer when heated, greatly improving the stability and reliability of the flooring structure and extending its actual service life.

[0012] Reduced processing difficulty and costs: Traditional processes require extremely high flatness of the solid wood core layer, while this solution only needs to ensure flatness during the processing of the wood-stone layer. Because the wood-stone layer is formed under high temperature and pressure, flatness can be precisely controlled during the forming process using molds and pressure. Its process is highly controllable and achieves high precision standards more easily than the solid wood core layer. Therefore, the requirements for processing precision of the solid wood core layer can be significantly reduced, decreasing the scrap rate caused by insufficient flatness of the solid wood core layer, simplifying the production process, reducing processing costs, and improving production efficiency.

[0013] Enhancing overall flooring performance: The wood-stone layer itself is highly hard and wear-resistant. When incorporated into the flooring structure, it significantly improves the floor's surface abrasion and scratch resistance, effectively resisting wear and tear from furniture movement and shoe friction during daily use. This reduces surface scratches and allows the flooring to maintain its good appearance and performance even after long-term use. Simultaneously, the wood-stone layer also enhances the overall compressive strength and deformation resistance of the flooring, further improving its suitability for various environments.

[0018] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0019] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0020] As described in the background section, in existing wood flooring structures, the solid wood core layer and the decorative layer are in direct contact. During use, due to the high temperature environment, the difference in their thermal expansion coefficients makes cracking and delamination very likely. Furthermore, during processing, the solid wood core layer needs to maintain a high degree of flatness to meet processing requirements and avoid subsequent bulging, which undoubtedly increases the processing difficulty.

[0021] Based on the above reasons, in order to solve the above problems, this utility model provides the following technical solution:

[0022] Example 1,

[0023] Please see the appendix Figure 1 and attached Figure 2 A wood-stone composite flooring includes a base layer, an intermediate layer and a surface layer arranged sequentially from bottom to top. The base layer is a wood veneer balancing layer 1. The intermediate layer includes a solid wood core layer 2, a wood-stone layer 3 and a decorative layer 4. The surface layer is a wear-resistant layer 5. The wood-stone layer 3 is formed by high temperature and high pressure pressing.

[0024] As mentioned above, the wood-stone layer placed between the solid wood core layer and the decorative layer makes the structure more stable and less prone to deformation, which is more in line with the current trend of using underfloor heating in the decoration industry. Traditional multi-layer solid wood flooring has a relatively fragile wood veneer surface layer that is easily scratched and dented by heavy objects. The wood-stone layer can effectively improve the structural stability of the flooring, thereby extending its service life.

[0025] Meanwhile, by setting up the wood and stone layer, only the flatness of the wood and stone layer needs to be ensured during processing. Since the wood and stone layer is formed by high temperature and high pressure, the flatness can be precisely controlled by the mold and pressure during processing. Its process is highly controllable and it is easier to achieve high precision standards compared with the solid wood core layer. This reduces the surface requirements of the solid wood core and increases the types of wood that can be used to make the solid wood core, thereby achieving the effect of reducing costs.

[0026] In this embodiment, the floor has dimensions of 380-3200mm in length, 80-1300mm in width, and 6-18mm in thickness. The thickness of the log veneer balancing layer 1 is 0.5mm, the thickness of the solid wood core layer 2 is 4.5-16.5mm, the thickness of the wood and stone layer 3 is 0.5-3.5mm, and the thickness of both the decorative layer 4 and the wear-resistant layer 5 is 0.1mm.

[0027] Example 2,

[0028] Based on Example 1, the materials of the log veneer balancing layer 1 and the solid wood core layer 2 are pine, poplar or eucalyptus. Because this type of wood has the characteristics of uniform texture, good stability and strong toughness, it can play a good role in balancing layer, and has good natural texture and grain, while also having a certain degree of elasticity and comfortable feel underfoot.

[0029] Example 3,

[0030] Based on Example 1, the wood-stone layer 3 is made of stone powder, wood fiber, and adhesive. First, wood fiber has a certain toughness and strength, and stone powder can fill the gaps between the wood fibers, making the board structure more compact. Then, through the bonding effect of the adhesive, the three form a tight whole, thus possessing high compressive and bending strength, thereby improving the wear and scratch resistance of the floor. Second, wood fiber itself has a natural texture, and after being combined with stone powder, it can still retain the natural texture and grain of wood to a certain extent, giving the floor a unique decorative effect and creating a warm and natural atmosphere. At the same time, stone powder has a certain flame-retardant effect, which can improve the fire resistance of the board. Compared with pure wood boards, this board made of stone powder and wood fiber is less likely to burn when exposed to open flame, providing better fire protection for buildings.

[0031] Example 4,

[0032] Based on Example 1, the wear-resistant layer 5 is made of aluminum oxide, which can effectively improve surface hardness and reduce daily scratches and wear.

[0033] Example 5,

[0034] Based on Example 1, the wood and stone layer 3 and the adjacent layers are connected by a cold-pressing followed by a hot-pressing method. Compared with adhesive bonding, this method can effectively reduce formaldehyde release and is more in line with the concept of environmental protection.

[0035] This stone-wood composite flooring ensures excellent performance during both processing and use, reduces processing difficulty, and extends service life.

[0036] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
