Abstract
Description
Technical Field

[0002] Colored aluminum composite calcium silicate board is an excellent building decoration material, typically consisting of a multi-layered structure including colored aluminum panels, calcium silicate boards, and rock wool insulation boards. The colored aluminum panels are lightweight, come in a variety of rich and glossy colors, while the calcium silicate boards are classified as Class A fire-resistant materials, possessing high strength, good toughness, and excellent waterproof, moisture-proof, heat-insulating, and sound-insulating properties. The rock wool insulation boards excel in thermal insulation, fire resistance, sound absorption and noise reduction, and moisture and water resistance.
[0003] Based on the excellent properties of its various layers, color-coated aluminum composite calcium silicate board boasts outstanding fire resistance, providing a reliable fire barrier in the event of a fire. It also possesses numerous other characteristics such as waterproofing, moisture resistance, heat insulation, sound insulation, and energy saving, while exhibiting a metallic decorative effect. Compared to pure metal boards, it offers a significant cost advantage, resulting in substantial economic benefits. Therefore, color-coated aluminum composite calcium silicate board is widely used in various fields, including building exteriors, interior decoration, and industrial construction.
[0004] However, during the production and processing of sheet materials, there are still problems such as easy wear and scratches on the surface of aluminum sheets, bulging and delamination after bonding aluminum sheets, insufficient bonding strength after aluminum sheets are combined with insulation boards, and deformation of finished sheet materials during storage, which urgently need to be solved. Utility Model Content
[0005] The purpose of this utility model is to provide an integrated heat insulation and decoration panel with high bonding strength of the decorative surface layer, which is not prone to bulging or delamination.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A thermal insulation and decorative integrated panel includes a decorative surface layer, a substrate layer, and a thermal insulation layer that are stacked and bonded together from top to bottom; the integrated thermal insulation and decorative panel has a plurality of closed cavities inside, the cavities being located below the decorative surface layer, and the upper part of the cavities penetrating the upper side surface of the substrate layer.
[0008] Furthermore, a plurality of receiving holes are formed on the substrate layer, the receiving holes penetrating the substrate layer vertically, and the internal space of the receiving holes forms the receiving cavity.
[0009] Furthermore, the receiving hole is a tapered hole, and the larger end of the receiving hole faces the decorative surface layer.
[0010] Furthermore, it also includes a backing layer, which is bonded to the underside of the thermal insulation layer, and the underside of the backing layer has several back holes.
[0011] Furthermore, the back hole is a conical hole, and the larger end of the back hole faces the thermal insulation layer.
[0012] Furthermore, the substrate layer is a steam-pressurized calcium silicate board layer.
[0013] Furthermore, the decorative surface layer is a colored aluminum layer, a stainless steel layer, or an aluminum composite panel layer, and the thermal insulation layer is a thermosetting board layer, an EPS layer, or a rock wool insulation layer.
[0014] Furthermore, the thickness of the decorative surface layer is 0.3-0.6 mm, the thickness of the substrate layer is 8-10 mm, and the thickness of the thermal insulation layer is 30-120 mm.
[0015] Furthermore, it also includes an electrostatic film layer, which is attached to the upper side of the decorative surface layer.
[0016] This utility model has the following beneficial effects:
[0017] 1. The internal cavity within the board can be used to remove adhesive and air during the bonding of the decorative surface layer, preventing bulging and delamination of the decorative surface layer caused by uneven adhesive buildup between the decorative surface layer and the substrate layer, or air trapped between the layers during adhesive drying, thus ensuring a firm bond to the decorative surface layer.
[0018] 2. After the adhesive material discharged into the inner cavity cures, it can further enhance the bonding strength between the decorative surface layer and the substrate layer, and improve the mechanical properties of the integrated insulation and decoration panel.
[0019] 3. The internal cavity also enables the effective discharge of water vapor, solving the problem of board bending and deformation caused by inconsistent moisture content on the contact and open surfaces of the decorative surface layer and the substrate layer during lamination.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0026] like Figure 1 , 2 As shown, this utility model discloses an integrated thermal insulation and decorative panel, comprising a decorative surface layer 1, a substrate layer 2, and a thermal insulation layer 3 stacked sequentially from top to bottom, and also including adhesive layers (not shown) disposed between the layers to provide adhesion. The decorative surface layer 1, substrate layer 2, and thermal insulation layer 3 are bonded and composited into one unit by corresponding adhesive layers. Each adhesive layer is made relatively independently using polyurethane adhesive, PUR adhesive, or other adhesives commonly used in the art.
[0027] The integrated thermal insulation and decorative panel has several enclosed cavities 4 inside. The cavities 4 are located below the decorative surface layer 1, and the upper part of the cavities 4 penetrates the upper side of the substrate layer 2. Therefore, before the decorative surface layer 1 and the substrate layer 2 are bonded together, the cavities 4 are not enclosed. That is, the upper side of the base panel has regular or irregular holes and grooves, and their internal space constitutes part or all of the cavities 4.
[0028] Taking the case where a receiving hole 5 is opened on the upper side of the substrate layer 2 as an example, the internal space of the receiving hole 5 constitutes a receiving cavity 4. When the decorative surface layer 1 and the substrate layer 2 are bonded together, if the adhesive layer between the decorative surface layer 1 and the substrate layer 2 is unevenly piled, some of the undried adhesive can be led out and accommodated through the receiving hole 5, ensuring that the adhesive layer between the layers is flat and uniform. This effectively improves defects such as excessively thick adhesive layer in some areas resulting in incomplete curing, insufficient adhesive in some areas causing gaps, and local stress concentration after the adhesive layer has cured. It also prevents the decorative surface layer 1 from blistering or delaminating after bonding, ensuring that the decorative surface layer 1 is firmly bonded.
[0029] Meanwhile, the adhesive material discharged into the receiving hole 5, that is, the adhesive material discharged into the receiving cavity 4, can further enhance the bonding strength between the decorative surface layer 1 and the substrate layer 2 after curing, and improve the mechanical properties of the integrated thermal insulation and decorative panel.
[0030] In addition, the receiving hole 5 also has a venting / vapor function, which can lead out the gas generated when the adhesive layer dries, and prevent the gas from remaining between the interface of the decorative surface layer 1 and the substrate layer 2, which would cause the decorative surface layer 1 to bulge after bonding. It can also release interlayer water vapor, and solve the problem of board bending deformation caused by the inconsistent moisture content of the contact surface and open surface of the decorative surface layer 1 and the substrate layer 2 when they are composited.
[0031] The opening depth of the receiving hole 5 can be set according to actual needs, and can be a blind hole or a [missing information - likely a type of hole]. Figure 2 The substrate layer 2 extends vertically through the substrate layer 2, and simultaneously removes adhesive and vents / vapor in the areas between the decorative surface layer 1 and the substrate layer 2, and between the substrate layer 2 and the thermal insulation layer 3. Preferably, the receiving hole 5 is a tapered hole with a diameter of 7-8 mm at the larger end and a diameter of 6-7 mm at the smaller end. The larger end of the receiving hole 5 faces the decorative surface layer 1, which can accelerate the adhesive removal speed at the interface of the decorative surface layer 1.
[0032] like Figure 3 , 4 As shown, the integrated thermal insulation and decorative panel also includes a backing layer 6 to enhance the overall strength of the panel. The backing layer 6 is bonded to the underside of the thermal insulation layer 3. Similar to the receiving hole 5, several back holes 7 are provided on the underside of the backing layer 6. Through these back holes 7, adhesive and mortar can be squeezed into the back holes 7 during panel installation, enhancing the bonding strength between the back side of the integrated panel and the mounting surface. Furthermore, the back holes 7 allow for vapor release during adhesive and mortar curing, preventing moisture accumulation. Preferably, the back holes 7 are tapered, with a diameter of 8-10 mm at the larger end and 6-8 mm at the smaller end. The larger end faces the thermal insulation layer 3, forming a hook structure after the adhesive and mortar have cured, resulting in better adhesion.
[0033] In preparing this integrated thermal insulation and decorative panel, the decorative surface layer 1 and the substrate layer 2 are typically laminated first, followed by the thermal insulation layer 3 and the backing layer 6. Among the layers, the decorative surface layer 1 is preferably a colored aluminum layer, offering rich colors and good luster; it can also be an aluminum composite panel layer, providing strong decorative appeal and lightweight properties; or a stainless steel layer, offering strong weather resistance and good impact resistance. The thickness T1 of the decorative surface layer 1 is 0.3-0.6 mm. An electrostatic film layer 8 is also attached to the upper side of the decorative surface layer 1, which reduces scratches and wear during production, transportation, processing, and installation, mitigating the risk of residual adhesive on the panel surface.
[0034] The substrate layer 2 is made of steam-pressurized calcium silicate board, which has higher flexural and tensile strength and durability than ordinary calcium silicate board, and can compensate for the impact of the internal porous structure on the strength and wind pressure resistance of the integrated board. The thickness T2 of the substrate layer 2 is approximately 8-10mm.
[0035] The thickness T3 of the thermal insulation layer 3 is 30-120mm. When a backing layer 6 is provided, the thermal insulation layer 3 can be made of rock wool, allowing the integrated panel to meet the energy-saving insulation requirements and Class A fire resistance requirements of different buildings. When a backing layer 6 is not provided, the thermal insulation layer 3 is preferably a Class A2 thermosetting board layer or an EPS (polystyrene) layer.
