Description

Technical Field

[0001] This utility model relates to the field of composite board technology, specifically to an indoor wear-resistant, moisture-proof, and environmentally friendly aluminum-resin composite board. Background Technology

[0002] Composite panels, due to their advantages of both lightweight and structural strength, are widely used in interior wall decoration, interior door panels, interior cabinet panels and other decoration scenarios, and have become a commonly used type of board in the current interior decoration field. In the long-term actual application process, it has been found that when adapting to the needs of indoor use, existing composite panels are more likely to come into contact with liquids such as water and cleaning agents in the indoor environment. In addition, daily use is prone to friction, which can easily lead to liquid penetration, resulting in oxidation and corrosion of the substrate, affecting the appearance integrity and service life of the board.

[0003] Meanwhile, changes in indoor temperature and stress transmission after installation can easily cause some composite panels to warp and crack due to insufficient side support stability and limited interlayer bonding strength, reducing the structural reliability of the panels. Therefore, there is an urgent need to develop a wear-resistant, moisture-proof, and environmentally friendly aluminum-coated resin composite panel for indoor use to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an indoor wear-resistant, moisture-proof, and environmentally friendly aluminum-resin composite board, which solves the technical problems of existing composite boards being prone to substrate oxidation and corrosion due to liquid penetration, and the composite boards being prone to warping and cracking due to insufficient side support and weak interlayer bonding, thus affecting structural reliability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an indoor wear-resistant, moisture-proof, and environmentally friendly aluminum-coated resin composite panel, comprising a first aluminum-coated composite panel, a second aluminum-coated composite panel, two sets of thermally broken aluminum materials, two independent environmentally friendly epoxy resin layers, and an aluminum honeycomb panel.

[0006] The first aluminum composite panel and the second aluminum composite panel are parallel to each other, and the length of the second aluminum composite panel is greater than that of the first aluminum composite panel. The outer surfaces of the first aluminum composite panel and the second aluminum composite panel are both covered with PVC film, and the outer surface of the PVC film is coated with water-based polyurethane wear-resistant coating.

[0007] Two sets of thermally broken aluminum profiles are fixed to the left and right ends of the inner sides of the first and second aluminum composite panels, respectively. The two ends of the second aluminum composite panel are aligned with the two ends of the thermally broken aluminum profiles. Two environmentally friendly epoxy resin layers are fixed to the inner surfaces of the first and second aluminum composite panels, respectively. The aluminum honeycomb panel is bonded and fixed to the two environmentally friendly epoxy resin layers by a two-component epoxy adhesive, and the outer wall of the aluminum honeycomb panel is completely bonded to the inner wall of the environmentally friendly epoxy resin layer.

[0008] Preferably, the thermally broken aluminum profile has a hollow, weight-reducing, and heat-insulating groove inside, which runs through the length of the thermally broken aluminum profile, and a butt-fitting installation groove is provided on the outer wall of the thermally broken aluminum profile, which extends along the length of the thermally broken aluminum profile.

[0009] Preferably, the aluminum honeycomb panel has a moisture-proof reinforced core layer inside, including an XPS extruded polystyrene board, a PU foam layer and a neutral silicone anti-mildew adhesive layer. The XPS extruded polystyrene board is located in the center of the aluminum honeycomb panel. The PU foam layer wraps around the outside of the XPS extruded polystyrene board to fill the gaps. The neutral silicone anti-mildew adhesive layer wraps around the outside of the PU foam layer and is bonded to the inner wall of the honeycomb holes of the aluminum honeycomb panel.

[0010] Preferably, the XPS extruded board has a closed-cell rate of not less than 95%, which is used to provide core support for the aluminum honeycomb panel and block water vapor penetration.

[0011] Preferably, the PU foam layer is made of a single-component moisture-curing polyurethane foam material.

[0012] Preferably, the composite panel is installed on the interior wall decoration surface, interior door panel or interior cabinet panel. During installation, it is connected and fixed to the interior installation frame through the butt joint mounting groove on the outside of the thermally broken aluminum material.

[0013] This utility model provides a wear-resistant, moisture-proof, and environmentally friendly aluminum-resin composite board for indoor use. Compared with the prior art, it has the following advantages.

[0014] 1. The PVC film on the outer surface of the first and second aluminum composite panels blocks liquid from contacting the substrate, preventing oxidation and corrosion. The water-based polyurethane wear-resistant coating enhances scratch resistance, together achieving wear resistance and corrosion prevention, solving the problem of surface damage. The two environmentally friendly epoxy resin layers release no harmful substances, meeting indoor environmental protection requirements and avoiding air pollution. The two sets of thermally broken aluminum materials provide side support, and the aluminum honeycomb panel disperses the stress. Combined with the strong bonding of the two-component epoxy adhesive, it effectively resists deformation, solves the problem of warping and cracking, and achieves wear resistance, corrosion prevention, environmental protection, and deformation resistance.

[0015] 2. XPS extruded polystyrene board blocks moisture penetration into the core and supports the aluminum honeycomb panel, solving the problem of insufficient moisture protection in the core. PU foam layer fills the gaps to enhance moisture protection and supplement the deformation resistance of the aluminum honeycomb panel core. Neutral silicone anti-mildew adhesive layer firmly bonds the PU foam layer to the aluminum honeycomb panel, preventing interlayer loosening and inhibiting mold, thus avoiding mold and corrosion in the core. The three work together to enhance moisture protection in the core, supplement deformation resistance and mold and corrosion prevention, solving the problems of water accumulation and mold growth in the core and interlayer loosening.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] First implementation method:

[0024] refer to Figure 1-2 A wear-resistant, moisture-proof and environmentally friendly aluminum-coated resin composite panel for indoor use includes a first aluminum-coated composite panel 1, a second aluminum-coated composite panel 103, two sets of thermally broken aluminum materials 2, two independent environmentally friendly epoxy resin layers 3 and an aluminum honeycomb panel 4.

[0025] The first aluminum composite panel 1 and the second aluminum composite panel 103 are parallel to each other, and the length of the second aluminum composite panel 103 is greater than that of the first aluminum composite panel 1. The outer surfaces of the first aluminum composite panel 1 and the second aluminum composite panel 103 are both covered with PVC film 101, and the outer surface of the PVC film 101 is coated with water-based polyurethane wear-resistant coating 102.

[0026] Two sets of thermally broken aluminum profiles 2 are respectively fixed to the left and right ends of the inner side of the first aluminum composite panel 1 and the second aluminum composite panel 103. The two ends of the second aluminum composite panel 103 are aligned with the two ends of the thermally broken aluminum profiles 2. Two environmentally friendly epoxy resin layers 3 are respectively fixed to the inner surface of the first aluminum composite panel 1 and the second aluminum composite panel 103. The aluminum honeycomb panel 4 is bonded and fixed to the two environmentally friendly epoxy resin layers 3 by a two-component epoxy adhesive, and the outer wall of the aluminum honeycomb panel 4 is completely attached to the inner wall of the environmentally friendly epoxy resin layer 3.

[0027] The thermally broken aluminum profile 2 has a hollow, weight-reducing, and heat-insulating groove 201 inside, which runs through the length of the thermally broken aluminum profile 2. The outer wall of the thermally broken aluminum profile 2 has a butt joint mounting groove 202, which extends along the length of the thermally broken aluminum profile 2. The composite panel is installed on the interior wall decoration surface, interior door panel, or interior cabinet panel. During installation, it is connected and fixed to the interior installation frame through the butt joint mounting groove 202 on the outer side of the thermally broken aluminum profile 2.

[0028] Working principle: During the use of the composite panel, the PVC film 101 on the outer surface of the first aluminum composite panel 1 and the second aluminum composite panel 103 is in direct contact with the external environment, which can physically block liquids such as water and cleaning agents from penetrating and contacting the aluminum composite panel substrate, thus preventing the substrate from oxidizing and corroding.

[0029] Meanwhile, the water-based polyurethane wear-resistant coating 102 on the outer surface of the PVC film 101 can resist scratches caused by daily friction and collision, reduce the risk of substrate exposure, and jointly achieve the surface wear-resistant and anti-corrosion effect.

[0030] Due to their environmentally friendly material properties, the two environmentally friendly epoxy resin layers 3 continuously prevent the release of harmful substances such as formaldehyde and benzene during their service life, ensuring the safety of the indoor environment. The two sets of thermally broken aluminum materials 2 are fixed to the inner ends of the first aluminum composite panel 1 and the second aluminum composite panel 103 to form a transverse support frame. With the honeycomb structure of the aluminum honeycomb panel 4, the aluminum honeycomb panel 4 can evenly distribute the external force to the entire panel surface. Furthermore, through the strong adhesion of the two-component epoxy adhesive, it is ensured that there is no interlayer separation between the aluminum honeycomb panel 4 and the environmentally friendly epoxy resin layer 3, effectively resisting transverse deformation and preventing the panel from warping and cracking.

[0031] During installation, the mating mounting groove 202 on the outside of the thermally broken aluminum profile 2 can be precisely matched and connected with the indoor installation frame to achieve quick fixation. At the same time, the hollow weight-reducing heat insulation groove 201 inside the thermally broken aluminum profile 2 reduces the overall weight of the panel while ensuring structural strength, and can also weaken heat transfer and help improve the heat insulation performance of the composite panel.

[0032] Second implementation method:

[0033] When similar composite boards are used in a humid indoor environment for a long time, it is found that the continuous high humidity in the environment can easily penetrate into the interior of the board, affecting the overall structural stability and service life of the composite board. Therefore, a moisture-proof and reinforced core layer is designed. The specific structure and working principle are as follows.

[0034] refer to Figure 3-5In the second embodiment of this utility model, the aluminum honeycomb panel 4 is provided with a moisture-proof reinforcing core layer 5, including an XPS extruded board 501, a PU foam layer 502 and a neutral silicone anti-mildew adhesive layer 503. The XPS extruded board 501 is located in the center of the aluminum honeycomb panel 4. The PU foam layer 502 wraps around the outside of the XPS extruded board 501 to fill the gap. The neutral silicone anti-mildew adhesive layer 503 wraps around the outside of the PU foam layer 502 and is bonded to the inner wall of the honeycomb holes of the aluminum honeycomb panel 4.

[0035] XPS extruded board 501 has a closed-cell rate of not less than 95% and is used to provide core support for aluminum honeycomb panel 4 and block water vapor penetration. PU foam layer 502 is made of single-component moisture-curing polyurethane foam material.

[0036] Working principle: When in use, the XPS extruded board 501 in the moisture-proof reinforced core layer 5 forms a dense water vapor barrier with a closed-cell rate of not less than 95%, which directly blocks external water vapor from longitudinally penetrating from the core of the aluminum honeycomb panel 4. At the same time, its rigid structure provides core support for the aluminum honeycomb panel 4, preventing the aluminum honeycomb panel 4 from collapsing locally due to stress or moisture.

[0037] After curing, the PU foam layer 502 on the outside of XPS extruded board 501 tightly fills the tiny gap between XPS extruded board 501 and neutral silicone anti-mildew adhesive layer 503, eliminating moisture retention channels and further enhancing the moisture-proof effect of the core. In addition, the elastic properties of the PU foam layer 502 can buffer the local stress in the core and supplement the deformation resistance of the aluminum honeycomb panel 4.

[0038] The neutral silicone anti-mold adhesive layer 503, which is wrapped around the outside of the PU foam layer 502, firmly bonds the PU foam layer 502 to the inner wall of the honeycomb holes of the aluminum honeycomb panel 4, preventing the core components from detaching from the aluminum honeycomb panel 4 and causing structural loosening. On the other hand, its anti-mold properties can inhibit the growth of mold in the adhesive gaps in a humid environment, prevent mold from corroding the core substrate, and ensure that the core of the composite board remains stable and dry for a long time.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
