[0031] The utility model discloses a composite board, which combines a decorative board layer, an adhesive layer and a base material layer, thereby not only having the effect and texture of a decorative board layer, but also greatly reducing the weight and cost of the board, and solving the problems existing in the prior art.

[0032] The following is a clear and detailed description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Figures 1 to 3 The composite board provided by the embodiment of the present invention includes a decorative board layer 1, an adhesive layer 2 and a base material layer 3 arranged in sequence from top to bottom;

[0033] The decorative board layer 1 is connected to the substrate layer 3 via the adhesive layer 2;

[0034] The substrate layer 3 is a foamed ceramic plate layer.

[0035] In the present invention, a thin layer of traditional thick aluminum plate, rock plate or other decorative plate is taken as the decorative plate layer 1 of the present invention, and then the foamed ceramic plate layer with the advantages of light weight and high strength is used as the substrate layer 3, and then the decorative plate layer 1 and the substrate layer 3 are combined using the adhesive layer 2. The composite plate obtained has the advantages and texture of traditional aluminum plate, rock plate or other decorative plates, and can greatly reduce the use of traditional aluminum plate, rock plate or other decorative plates. For aluminum plate, it can greatly reduce the cost, and for rock plate, it can greatly reduce the weight.

[0036] It should be noted that the thickness of the decorative board layer 1 has different options depending on different materials. For example, when the decorative board layer 1 is an aluminum plate, a thickness of 0.1 to 0.5 cm can be selected. For example, when the decorative board layer 1 is a rock plate, a thickness of 0.5 to 1.5 cm can be selected. The specific design should also be based on the total thickness of the composite board, which is not limited here.

[0037] Preferably,

[0038] The substrate layer 3 is composed of a foamed ceramic plate layer 31 and a nylon backing mesh layer 32 , wherein the adhesive layer 2 , the foamed ceramic plate layer 31 and the nylon backing mesh layer 32 are arranged in sequence from top to bottom.

[0039] Preferably,

[0040] The density of the foamed ceramic plate layer 31 is 0.42-0.48 g / cm3 .

[0041] See also Figure 2 It should be noted that the density of the foamed ceramic plate layer 31 of the present invention is 0.42-0.48 g / cm 3 The foamed ceramic plate layer 31 of this density takes into account the advantages of light weight and high strength. The following example illustrates that in today's high-rise buildings, aluminum plates are often used to decorate the exterior walls. For exterior wall decorative aluminum plates, relatively thick aluminum plates are generally used because aluminum plates with too small a thickness are prone to deformation. Therefore, the cost of exterior wall decorative aluminum plates is relatively high. When the composite plate of the present invention is used, the decorative plate layer 1 is an aluminum plate. Only a thin layer of aluminum plate is needed to achieve the same decorative effect as the exterior wall decorative aluminum plate. Moreover, the base material layer 3 made of the foamed ceramic plate layer 31 is not only strong, but also has the advantages of light weight and low cost. For another example, when decorating the lobby nowadays, large ceramic plates, marble plates or rock plates are often used for decoration. The biggest drawback of these plates is their heavy weight. Not only are the transportation costs high, but they are also inconvenient to install and have high load-bearing requirements for the wall. After using the composite plate of the present invention, the weight can be greatly reduced, solving the above problems.

[0042] Preferably,

[0043] The thickness of the foamed ceramic plate layer 31 is 10 mm to 30 mm.

[0044] Preferably,

[0045] The density of the foamed ceramic plate layer 31 is 0.45 g / cm 3 .

[0046] In the present invention, after many tests, the density of the foamed ceramic plate layer 31 is 0.45g / cm 3 It can achieve a balance between strength and light weight.

[0047] Preferably,

[0048] The adhesive layer 2 is a PUR (Polyurethane Reactive) hot melt adhesive layer.

[0049] Preferably,

[0050] The decorative board layer 1 is a combination of one or more of an aluminum board layer, a rock board layer, a ceramic board layer or a wood grain board layer.

[0051] Preferably,

[0052] The decorative plate layer 1 is an aluminum plate layer;

[0053] See also Figure 3The composite panel also includes a skin-feeling film layer 4, a nano-wear-resistant paint layer 5, a nano-hardened paint layer 6, a high-weather-resistant ink layer 7 and a weather-resistant powder layer 8, which are arranged in sequence from top to bottom, wherein the weather-resistant powder layer 8 is arranged on the aluminum plate layer.

[0054] In an embodiment of the present invention, a skin-feeling film layer 4, a nano-wear-resistant paint layer 5, a nano-hardened paint layer 6, a high-weather-resistant ink layer 7 and a weather-resistant powder layer 8 can also be provided on the aluminum plate layer, wherein the weather-resistant powder layer 8 is for facilitating the printing of ink, the high-weather-resistant ink layer 7 is a pattern printed on the aluminum plate layer, the nano-wear-resistant paint layer and the 5 nano-hardened paint layer 6 are for protecting the printed pattern, and the skin-feeling film layer 4 is for improving the tactile effect.

[0055] Preferably,

[0056] The decorative plate 1 is an aluminum plate layer; a protective film 9 is also provided on the side of the skin-feeling film layer 4 away from the aluminum plate layer.

[0057] In the present invention, the composite board may further include a protective film 9, which is compounded on the skin-feeling film layer 4 during production to protect the composite board from damage during transportation or other situations. The protective film 9 should be torn off before use, which is not limited here.

[0058] The composite panel of the present invention comprises, arranged from top to bottom, a decorative panel layer 1, an adhesive layer 2, and a substrate layer 3. The decorative panel layer 1 is connected to the substrate layer 3 via the adhesive layer 2; the substrate layer 3 is a foamed ceramic panel. By combining the decorative panel layer 1, the adhesive layer 2, and the substrate layer 3, the composite panel of the present invention not only retains the effects and texture of the decorative panel layer 1, but also significantly reduces the weight and cost of the panel, resolving the problems of the prior art.

[0059] The above is a detailed introduction to a composite board provided by the present invention. For those skilled in the art, according to the concept of the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
