Description

Technical Field

[0001] This utility model relates to the technical field of acrylic decorative panels, specifically an acrylic decorative panel for oxidation prevention. Background Technology

[0002] Acrylic (polymethyl methacrylate, PMMA) decorative panels are widely used in interior and exterior decoration, advertising displays, furniture accessories and other fields due to their high transparency, weather resistance and good processing performance. However, traditional acrylic materials are prone to oxidative degradation when exposed to ultraviolet rays, humidity or high temperature environments for a long time, resulting in problems such as yellowing, embrittlement and reduced light transmittance, which seriously affect their aesthetics and service life. In addition, the oxidation process may also cause stress concentration inside the material, increasing the risk of cracking and limiting its further application in high-end decorative scenarios.

[0003] Existing acrylic decorative panels mainly improve weather resistance by adding ultraviolet absorber coatings (such as UV-531 and UV-327) or antioxidant coatings (such as hindered phenols and phosphites). However, these additive coatings are prone to migration or decomposition, which can lead to a decrease in protective effect. For example, ordinary UV coatings will powder and peel off after a period of outdoor use and cannot resist the erosion of complex environments in the long term. They need to be replaced or recoated regularly. However, traditional acrylic decorative panels are usually set as a whole, which requires disassembly and reassembly of the acrylic decorative panel for replacement or recoating of the antioxidant coating, resulting in high maintenance costs for acrylic decorative panels. In view of the above problems, this application proposes an anti-oxidation acrylic decorative panel. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-oxidation acrylic decorative panel, which divides the acrylic panel into an acrylic panel base layer and an acrylic panel surface layer. The anti-oxidation coating on the surface of the acrylic panel enhances the anti-oxidation performance of the acrylic panel, and the acrylic panel surface layer can be disassembled and replaced separately, reducing maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-oxidation acrylic decorative panel includes an acrylic panel body with a frame nested around its perimeter. The acrylic panel body is composed of an acrylic base layer and an acrylic surface layer bonded together. The side of the acrylic surface layer away from the acrylic base layer is coated with an anti-oxidation coating. The acrylic base layer is fixedly embedded in the frame, and the acrylic surface layer is movably embedded in the frame. Connectors for connecting to the frame are provided on the side of the acrylic surface layer.

[0007] Preferably, the connector includes an ear block disposed on the side of the acrylic sheet surface layer and a connecting screw passing through the ear block, and the frame is provided with a screw hole that engages with the threaded connection of the connecting screw.

[0008] Preferably, a raised strip is provided on the side of the acrylic sheet base layer, and the raised strip is embedded in the inner wall of the frame.

[0009] Preferably, the sides of the acrylic sheet base layer and the acrylic sheet surface layer that are far apart from each other are flush with the two sides of the frame.

[0010] Preferably, the frame has a slot on one side facing the acrylic sheet surface, and the ear block is embedded in the slot.

[0011] Preferably, the ear block has a first adapter groove, and the tail end of the connecting screw can be completely embedded in the first adapter groove.

[0012] Preferably, a protruding post is provided at the position where the connecting screw passes through the ear block. The protruding post is located on the side of the ear block facing the frame. A second adapter groove is provided on the frame. The protruding post is fitted into the second adapter groove. The screw hole is opened on the inner wall of the second adapter groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention improves the wear resistance of the acrylic sheet by nesting a frame around its perimeter. By dividing the acrylic sheet into an acrylic base layer and an acrylic surface layer, and by applying an anti-oxidation coating to the surface layer, the anti-oxidation performance of the acrylic sheet is enhanced, the oxidation reaction caused by ultraviolet radiation is reduced, and the durability of the acrylic sheet is improved.

[0015] This invention divides the acrylic sheet into an acrylic base layer and an acrylic surface layer. The acrylic base layer is fixedly nested with the frame, and the acrylic surface layer is connected to the frame via connectors. Connecting screws pass through lugs and are screwed into threaded holes on the frame, allowing the acrylic surface layer to be embedded within the frame. By loosening and unscrewing the connecting screws, the acrylic surface layer can be detached from the acrylic base layer and the frame. When the anti-oxidation coating is nearing the end of its service life or peeling off, the acrylic surface layer can be removed and replaced or recoated without disassembling and replacing the entire acrylic sheet, reducing maintenance costs and making it more practical.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Example

[0025] Please see Figures 1 to 5 The present invention preferably provides the following technical solution: an anti-oxidation acrylic decorative panel, comprising an acrylic panel body, wherein a frame 1 is nested around the periphery of the acrylic panel body. By nesting the frame 1 around the periphery of the acrylic panel body, the wear resistance of the side of the acrylic panel body can be improved. The frame 1 may be made of materials such as aluminum alloy.

[0026] In a further embodiment, the acrylic sheet is composed of an acrylic sheet base layer 2 and an acrylic sheet surface layer 3 bonded together. The side of the acrylic sheet surface layer 3 away from the acrylic sheet base layer 2 is coated with an anti-oxidation coating 4. The anti-oxidation coating 4 enhances the anti-oxidation performance of the acrylic sheet, reduces oxidation caused by ultraviolet radiation, and improves the durability of the acrylic sheet. Specifically, the anti-oxidation coating 4 includes, but is not limited to, a UV coating. The acrylic sheet base layer 2 is fixedly embedded in the frame 1, and the acrylic sheet surface layer 3 is movably embedded in the frame 1. The side of the acrylic sheet surface layer 3 is provided with a connector that connects to the frame 1, making the acrylic sheet surface layer 3 detachable. Through this structural design, when the anti-oxidation coating 4 is nearing the end of its service life or falls off, the acrylic sheet surface layer 3 can be removed and replaced or the anti-oxidation coating 4 can be recoated separately without disassembling and replacing the entire acrylic sheet, thus reducing maintenance costs.

[0027] In this embodiment, the connector includes an ear block 6 located on the side of the acrylic sheet surface layer 3 and a connecting screw 7 passing through the ear block 6. The frame 1 has a screw hole 12 that is threaded to the connecting screw 7. By threading the connecting screw 7 through the ear block 6 and into the screw hole 12 on the frame 1, the acrylic sheet surface layer 3 and the frame 1 can be connected, so that the acrylic sheet base layer 2, the acrylic sheet surface layer 3 and the frame 1 are connected as a whole. By loosening and unscrewing the connecting screw 7, the acrylic sheet surface layer 3 can be separated from the acrylic sheet base layer 2 and the frame 1.

[0028] In a further embodiment, a raised strip 5 is provided on the side of the acrylic sheet base 2. The raised strip 5 is embedded in the inner wall of the frame 1, improving the stability of the nesting of the acrylic sheet base 2 and the frame 1. The sides of the acrylic sheet base 2 and the acrylic sheet surface layer 3 that are far apart from each other are flush with the two sides of the frame 1. In addition, a slot 8 is provided on the side of the frame 1 facing the acrylic sheet surface layer 3. The ear block 6 is embedded in the slot 8. A first adapter groove 9 is provided on the ear block 6. The tail end of the connecting screw 7 can be completely embedded in the first adapter groove 9, which improves the integrity of the acrylic sheet base 2, the acrylic sheet surface layer 3 and the frame 1, and makes the surface of the acrylic sheet flat, improving the aesthetics.

[0029] In this embodiment, a protruding post 10 is provided at the position where the connecting screw 7 passes through the ear block 6. The protruding post 10 is located on the side of the ear block 6 facing the frame 1. A second adapter groove 11 is provided on the frame 1. The protruding post 10 is fitted into the second adapter groove 11. The screw hole 12 is opened on the inner wall of the second adapter groove 11. The nesting and cooperation of the protruding post 10 and the second adapter groove 11, along with the thickening design at the position where the connecting screw 7 passes through the ear block 6, improves the structural strength of the assembly of the connecting screw 7 and the ear block 6.

[0030] In use, the wear resistance of the acrylic sheet's sides can be improved by nesting the frame 1 around its perimeter. The acrylic sheet is divided into an acrylic base layer 2 and an acrylic surface layer 3, with the base layer 2 fixedly nested to the frame 1. The surface layer 3 is connected to the frame 1 via connectors. Connecting screws 7 are passed through lugs 6 and screwed into the screw holes 12 on the frame 1, allowing the surface layer 3 to be embedded within the frame 1. The acrylic base layer 2, surface layer 3, and frame 1 are connected as a single unit. The anti-oxidation coating 4 on the surface of the acrylic surface layer 3 enhances the acrylic sheet's anti-oxidation properties and reduces oxidation caused by ultraviolet radiation. The reaction is as follows: since the acrylic sheet surface layer 3 and the acrylic sheet base layer 2 are flush with the two sides of the frame 1 respectively, the tail end of the connecting screw 7 is embedded in the first adapter groove 9, and the ear block 6 is embedded in the slot 8, which improves the integrity of the acrylic sheet base layer 2, the acrylic sheet surface layer 3 and the frame 1. The surface of the acrylic sheet is flat, ensuring aesthetics. Furthermore, by unscrewing the connecting screw 7, the acrylic sheet surface layer 3 can be removed separately from the acrylic sheet base layer 2 and the frame 1. When the anti-oxidation coating 4 is nearing the end of its service life or falls off, the acrylic sheet surface layer 3 can be removed and replaced or the anti-oxidation coating 4 can be recoated without disassembling and replacing the entire acrylic sheet, reducing maintenance costs and making it more practical.
