[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] See Figures 1-3 This embodiment discloses a method for preparing a lightweight decorative panel with heat insulation function, the structure of which is as follows:

[0036] The decorative panel consists of a base plate 101, a frame layer 102, an insulation board 103, and a decorative panel layer 104 from bottom to top. The base plate 101, the frame layer 102, the insulation board 103, and the decorative panel layer 104 are connected by adhesive to form an integrated structure.

[0037] The skeleton layer 102 is mainly composed of several horizontal beams and vertical beams 105 perpendicular to each other. The grid formed by the horizontal beams and vertical beams 105 is filled with sound insulation material. Both sides of the skeleton layer 102 are provided with closed panels. The insulation board 103 includes a panel, a bottom plate and a polyurethane insulation layer disposed between the panel and the bottom plate. Several metal sleeves 106 are provided on both the panel and the bottom plate, and the metal sleeves 106 extend into the polyurethane insulation layer.

[0038] The specific preparation method is as follows:

[0039] Step 1: Prepare a grid structure by splicing or welding the horizontal beams and vertical beams 105, fill the grid formed by the horizontal beams and vertical beams 105 with sound insulation material, and trim and align the two sides.

[0040] Step 2: Secure the enclosure plate to the horizontal and vertical beams 105;

[0041] Step 3: Apply adhesive to the surfaces of the substrate 101, the skeleton layer 102, the insulation board 103, and the decorative board layer 104 in sequence, and then bond the substrate 101, the skeleton layer 102, the insulation board 103, and the decorative board layer 104 together to form an integrated structure.

[0042] This invention mainly consists of a base plate 101, a frame layer 102, an insulation board 103, and a decorative panel layer 104. In practical use, the frame layer is mainly composed of several horizontal and vertical beams 105 perpendicular to each other. The grid formed by the horizontal and vertical beams 105 is filled with sound-insulating material. Both sides of the frame layer 102 are equipped with sealing plates. The grid structure formed by the horizontal and vertical beams 105 effectively improves the bending strength of the decorative panel layer 104, preventing deformation during use. Simultaneously, the metal sleeves 106 on the panel and base plate extend into the polyurethane insulation layer, making the connection between the panel and base plate and the polyurethane insulation layer more secure and preventing separation of the base plate, panel, and polyurethane insulation layer. This invention has the advantage of good bending resistance and good thermal insulation and sound insulation effects in practical use.

[0043] The decorative panel layer 104 is provided with an installation groove 107 for installing decorative paintings; a pressure strip 108 is provided around the surface of the decorative panel layer 104, and the pressure strip 108 is provided with a protrusion. After the pressure strip 108 is fixedly installed on the decorative panel layer 104, the pressure strip 108 and the surface of the decorative panel layer 104 form the installation groove 107.

[0044] This setup allows for quick installation of decorative paintings without altering the structure of the decorative panel layer 104, as the painting can be installed via the pressure strip 108.

[0045] In step 3, pressure bonding is used when bonding the substrate 101, the skeleton layer 102, the insulation board 103, and the decorative board layer 104. Using pressure makes the bonding more secure.

[0046] Furthermore, in some embodiments, the enclosure plate is fixed to the crossbeams and vertical beams 105 using pins; this arrangement enables a fixed connection between the enclosure plate and the crossbeams and vertical beams 105.

[0047] The decorative panel layer 104 is provided with an edge banding plate 109 at its edge, which can achieve the purpose of sealing the side edges.

[0048] In some preferred embodiments, the metal sleeve 106 has a different diameter, which allows the metal sleeve 106 to extend into different depths of the polyurethane insulation layer, thereby improving the connection effect.

[0049] Furthermore, in some specific cases, the decorative panel layer 104 also includes a pressure plate 110 and a sealing mesh 111. The sealing mesh 111 includes a first sealing mesh 112 and a second sealing mesh 113. The first sealing mesh 112 is located between the insulation board 103 and the skeleton layer 102. After the first sealing mesh 112 covers the skeleton layer 102 and the substrate 101 together, the edge of the first sealing mesh 112 is located at the bottom of the substrate.

[0050] The second encapsulation mesh 113 is located between the decorative panel layer 104 and the insulation board 103. After the second encapsulation mesh 113 covers the insulation board 103, the skeleton layer 102 and the substrate 101, the edge of the second encapsulation mesh 113 is located at the bottom of the basic layer and covers the first encapsulation mesh 112. After the pressure plate 110 is fixedly connected to the basic layer, the first encapsulation mesh 112 and the second encapsulation mesh 113 are fixed.

[0051] This configuration creates an encapsulation structure. The first encapsulation mesh 112 encapsulates the skeleton layer 102 and the substrate 101, making the skeleton layer 102 and the substrate a single, integrated structure. Here, adhesion is not only provided by glue, but the first encapsulation mesh also applies pressure, making the connection between the skeleton layer 102 and the substrate 101 more stable, improving the anti-detachment effect, and resulting in a more stable overall structure. Simultaneously, the second encapsulation mesh 113 fixes the insulation board 103 to the skeleton layer 102 in an encapsulated manner. Under the action of the first and second encapsulation meshes 112 and 113, the insulation board 103, the skeleton layer 102, and the substrate are encapsulated and secured, effectively improving the connection effect.

[0052] The first encapsulation mesh 112 and the second encapsulation mesh 113 are either glass fiber mesh or metal mesh.

[0053] Furthermore, in actual use, the substrate 101 is provided with a first groove 114 and a second groove 115. A first locking block 116 is provided in the first groove 114, and a second locking block 117 is provided in the second groove 115. The first locking block 116 is used to press the first encapsulation mesh 112 into the first groove 114, and the second locking block 117 is used to press the second encapsulation mesh 113 into the second groove 115. Under the action of the first locking block 116 and the second locking block 117, the first encapsulation mesh 112 and the second encapsulation mesh 113 can be fixed. At the same time, the bottom plate is provided to fix the first locking block 116 and the second locking block 117 into the first groove 114 and the second groove 115, so as to prevent the first encapsulation mesh 112 and the second encapsulation mesh 113 from falling off, which has a good anti-detachment effect.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the invention.

It should be noted that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
