Description

Technical Field

[0001] This utility model relates to the field of decorative structure technology, and in particular to a composite fireproof wood veneer structure. Background Technology

[0002] Wood veneer is a common building decoration material. It is made by processing natural wood or artificial boards into boards with certain specifications and decorative effects. It is often used to decorate the surfaces of interior and exterior walls, ceilings, furniture and other surfaces.

[0003] In current domestic wood veneer structures with complex curved surfaces, kraft paper is commonly used as the base material and spliced ​​with wood veneer. The kraft paper and wood veneer are bonded together with adhesive mixed on-site. This structure has the following defects: 1. The wood veneer is easily affected by changes in environmental humidity, resulting in problems such as blistering, cracking, and mold; 2. It is difficult to control the adhesive ratio on-site, leading to unstable bonding strength.

[0004] Therefore, the performance of existing wood veneer structures needs further improvement. Utility Model Content

[0022] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0023] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0025] An embodiment of this utility model provides a composite fireproof wood veneer structure, such as... Figure 1 As shown, the structure includes an engineering base layer 100, a protective functional layer 200, and a decorative functional layer 300 arranged sequentially along a preset direction. The engineering base layer 100 is located near the wall and serves as the engineering base for the entire wood veneer structure. The engineering base layer 100 includes a cork pad 110. The protective functional layer 200 includes a fiberglass cloth 210 and a fireproof layer 220 arranged sequentially along a preset direction. The fiberglass cloth 210 forms a moisture-proof barrier layer, achieving a water vapor permeability of less than 0.18 g / m²·24h, thus preventing moisture erosion of the engineering base layer 100. The fireproof layer 220 provides fire resistance to the entire wood veneer structure. The decorative functional layer 300 includes a non-woven fabric 310 and a wood veneer 320 arranged sequentially along a preset direction. The non-woven fabric 310 and the wood veneer 320 are bonded together using a hot-melt composite process, which effectively controls the deformation rate of the wood grain.

[0026] In this embodiment, the protective functional layer 200 includes a fiberglass cloth 210, which can isolate and prevent moisture, making the wood veneer 320 less susceptible to the humidity of the wall. Simultaneously, the non-woven fabric 310 and the wood veneer 320 are bonded together via a hot-melt composite process, eliminating the need for on-site adhesive mixing and avoiding interference from the on-site construction environment, resulting in a more stable bond. This improves the overall performance of the wood veneer structure.

[0027] In some embodiments, the non-woven fabric 310 and the fireproof layer 220 are connected by adhesive, the fireproof layer 220 and the fiberglass cloth 210 are connected by adhesive, and the fiberglass cloth 210 and the cork mat 110 are also connected by adhesive. By bonding the layers together, the resulting wood veneer structure is soft, can be rolled up, and is convenient for on-site installation.

[0028] In some embodiments, the nonwoven fabric 310 may be produced using a cross-laying process, such that its tensile strength is greater than or equal to 18 MPa.

[0029] In some embodiments, the fire-resistant layer 220 is aluminum foil. Aluminum foil can provide a fire barrier at a high temperature of 650°C, with an oxygen index of over 32%, resulting in better fire resistance. Of course, other fire-resistant materials can also be selected for the fire-resistant layer 220 according to actual needs.

[0030] In some embodiments, the cork pad 110 has a thickness of 1.0 mm to provide effective base support, the protective functional layer 200 has a thickness of 0.15 mm to ensure fire and moisture resistance, and the decorative functional layer 300 has a thickness of 0.25 mm, so that both the non-woven fabric 310 and the wood veneer 320 have a certain thickness, which facilitates the combination of the two through a hot melt composite process.

[0031] In some embodiments, such as Figure 2 As shown, the engineering base layer 100 in this embodiment also includes a buffer adhesive layer 120, which is adhered and fixed to the side of the cork pad 110 away from the fiberglass cloth 210. Combining the cork pad 110 with the buffer adhesive layer 120 can provide cushioning and impact protection, as well as sound insulation and noise reduction, further enhancing the performance of the entire wood veneer structure.

[0032] Furthermore, the buffer layer 120 is a butyl rubber layer. Butyl rubber layers have advantages such as low water vapor permeability, high adhesion, aging resistance and stable properties. When applied in the construction field, it can provide excellent sealing and waterproofing.

[0033] Furthermore, the butyl rubber layer is evenly coated at 320g / ㎡ on the side of the cork pad 110 away from the fiberglass cloth 210. The evenly coated butyl rubber layer is not easy to delaminate, has a high anti-mildew level, a low smoke density level, and a lower carbonization rate than traditional wood veneer.

[0034] Among them, a coating roller can be used, employing 105℃ zoned temperature control and 100-180kg / cm² temperature. 2 Dynamic pressure compensation technology, combined with a 50cm / s precision conveyor line, ensures that the butyl rubber layer is uniformly coated at 320g / ㎡.

[0035] In some embodiments, the preset direction is perpendicular to the wall and away from the wall, that is, the engineering base layer 100 is the inner layer close to the wall, and the decorative functional layer 300 is the outer layer away from the wall.

[0036] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
