Description

Technical Field

[0001] This application relates to the field of integrated wall panel technology, specifically to a heat-insulating bamboo and wood fiber integrated wall panel. Background Technology

[0002] Integrated wall panels are a type of modular interior decoration material, typically composed of a substrate layer, a decorative layer, and a protective layer. Depending on the material of the substrate layer, they can be classified into various types, such as bamboo and wood fiber integrated wall panels, aluminum alloy integrated wall panels, and stone-plastic integrated wall panels. In existing technologies, bamboo and wood fiber wall panels mostly rely on chemical foaming materials or mineral wool filling to achieve thermal insulation. This material dependence makes them prone to problems such as material aging and powdering with long-term use, leading to a decline in thermal insulation performance. Therefore, a thermal insulation type of bamboo and wood fiber integrated wall panel is proposed. Utility Model Content

[0003] The purpose of this application is to address the technical problem that most thermal insulation materials rely on chemical foaming materials or mineral wool filling, which are highly dependent on materials and are prone to aging and pulverization after long-term use, leading to a decline in thermal insulation performance. This application provides a thermal insulation bamboo and wood fiber integrated wall panel.

[0006] Furthermore, the honeycomb pores are provided with spiral guide vanes extending in an involute shape.

[0007] Furthermore, a reinforcing structure is provided between the substrate layer and the microporous transition layer. The reinforcing structure includes a woven fiber layer with interlaced warp and weft fibers. Hemispherical protrusions are formed at the weaving nodes of the fiber layer, and buffer air cavities are formed between two adjacent hemispherical protrusions.

[0008] Furthermore, a support column is provided on the concave mirror, and a hollow reflective channel is constructed inside the support column. The inner wall of the hollow reflective channel is coated with a metal reflective film.

[0009] Furthermore, multiple spacers are provided between the decorative layer and the reflective heat insulation layer, and between the reflective heat insulation layer and the protective layer, so that air gaps are formed between the decorative layer and the reflective heat insulation layer, and between the reflective heat insulation layer and the protective layer.

[0010] Furthermore, the spacer column is truncated cone-shaped with a light-diffusing protrusion at its tip.

[0011] Furthermore, a separation layer is provided on the side of the substrate layer away from the microporous transition layer, and a silver reflective layer is plated on the side of the separation layer facing the substrate layer.

[0012] Furthermore, a waterproof layer is provided on the side of the separator layer away from the silver reflective layer.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1-7 As shown in one embodiment of this application, a heat-insulating bamboo and wood fiber integrated wall panel includes a substrate layer 1, a microporous transition layer 2, a heat-insulating structural layer 3, a heat-reflective structural layer, a decorative layer 4, a reflective heat-insulating layer 5, and a protective layer 6 stacked sequentially. The reflective heat-insulating layer 5 is made of aluminum, silver, or stainless steel. In this embodiment, the reflective heat-insulating layer 5 is made of aluminum. The heat-insulating structural layer 3 is constructed with multiple honeycomb holes 7, which are distributed in an array. The two ends of the honeycomb holes 7 face the microporous transition layer 2 and the heat-reflective structural layer, respectively. In actual use, the end of the honeycomb holes 7 facing the microporous transition layer 2 should be orthogonally arranged with the matrix fibers of the substrate layer 1 to guide the heat flow path and extend the heat transfer path by using the fiber wiring. The microporous transition layer 2 is constructed with multiple through-holes 8, the diameter of which is smaller than the diameter of the honeycomb holes 7. The heat-reflective structural layer includes multiple convex lenses 9 and concave mirrors 10 arranged alternately.

[0024] In use, the heat energy is first reflected by the reflective heat insulation layer 5, and then the heat reflection structure is formed by the convex lens 9 and the concave mirror 10. The array of convex lenses 9 focuses the incident heat radiation, and the array of concave mirrors 10 performs secondary reflection, forming a synergistic reflection effect. At the same time, an air micro-layer is formed between the heat insulation structure layer 3 and the decorative layer 4, producing an additional heat insulation effect. Then, the gradient heat insulation structure is formed by the honeycomb holes 7 and the through-holes 8. The through-holes 8 generate small airflow resistance, forming a multi-level thermal resistance gradient from coarse to fine, thus forming a multi-level thermal resistance mechanism to achieve the heat insulation effect.

[0025] In summary, this application abandons the traditional material modification method and achieves the insulation effect by forming multiple thermal resistance mechanisms through structural insulation design. It avoids material dependence, avoids problems such as material aging and pulverization during long-term use, and reduces the decay of insulation performance, thus making it more practical.

[0026] like Figure 3 As shown, in some embodiments, a spiral guide plate 11 extending in an involute shape is provided inside the honeycomb hole 7, and the spiral guide plate 11 is fixed inside the honeycomb hole 7.

[0027] Referring to the above, during use, the spiral guide vane 11 induces local vortices in the air, prolonging the residence time of the gas in the honeycomb holes 7, while disrupting the natural air convection pattern and reducing the convective heat transfer coefficient, thus making it more conducive to heat preservation.

[0028] like Figure 3 As shown, in some embodiments, a reinforcing structure is provided between the substrate layer 1 and the microporous transition layer 2. The reinforcing structure includes a woven fiber layer 12 with interlaced warp and weft fibers. A hemispherical protrusion 13 is formed at the weaving node of the fiber layer 12, and a buffer air cavity is formed between two adjacent hemispherical protrusions 13.

[0029] Referring to the above, during use, the point contact heat transfer mode is formed by the hemispherical protrusion 13 to achieve thermal bridge blocking. Compared with planar contact, the effective heat transfer area can be reduced. The difference in thermal expansion between layers is absorbed by the buffer air cavity to achieve stress buffering, prevent the thermal insulation performance from being reduced due to structural cracking, and is more conducive to thermal insulation. At the same time, the combination of fiber braided layer 12 and buffer air cavity can simultaneously achieve sound insulation and noise reduction.

[0030] like Figure 7 As shown, in some embodiments, a support column 14 is provided on the concave mirror 10. The support column 14 is fixed on the concave mirror 10. A hollow reflective channel 15 is constructed inside the support column 14. The hollow reflective channel 15 is distributed along the length direction of the support column 14. The inner wall of the hollow reflective channel 15 is coated with a metal reflective film 16.

[0031] Referring to the above, in use, the hollow reflective channel 15 and the metal reflective film 16 together construct a dual mechanism of specular reflection and total reflection to achieve a composite reflection path. At the same time, the support column 14 converts the heat flow into lateral diffusion, increases the length of the heat flow transfer path, and achieves heat flow guidance, which is more conducive to heat preservation.

[0032] like Figure 5 As shown, in some embodiments, multiple spacer columns 17 are provided between the decorative layer 4 and the reflective heat insulation layer 5, and between the reflective heat insulation layer 5 and the protective layer 6, so that air gaps are formed between the decorative layer 4 and the reflective heat insulation layer 5, and between the reflective heat insulation layer 5 and the protective layer 6 through the spacer columns 17.

[0033] Referring to the above, when using it, the air gap can further reduce the contact heat transfer coefficient, which is more conducive to heat preservation.

[0034] like Figure 5 As shown, in some embodiments, the spacer post 17 is constructed in the shape of a frustum and has a light-diffusing protrusion 18 at its tip;

[0035] Referring to the above, during use, the frustum-shaped structure of the spacer 17 can optimize the light refraction angle, and the light diffusion protrusion 18 can disperse surface stress, preventing the expansion of micro-cracks that could lead to thermal insulation failure.

[0036] like Figure 1 As shown, in some embodiments, a separation layer 19 is provided on the side of the substrate layer 1 away from the microporous transition layer 2, and a silver reflective layer 20 is plated on the side of the separation layer 19 facing the substrate layer 1.

[0037] Referring to the above, during use, the silver reflective layer 20 can further reflect heat energy, which is more conducive to heat preservation. In actual installation, the separator layer 19 can contact the wall surface, thereby separating the base material layer 1 from the wall surface. This not only makes heat preservation more effective, but also provides a certain degree of waterproofing and improves the stability of use.

[0038] like Figure 1 As shown, in some embodiments, a waterproof layer 21 is provided on the side of the separator 19 away from the silver reflective layer 20;

[0039] Referring to the above, the waterproof layer 21 is used to improve waterproof performance and further enhance stability during use.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
