[0001] The utility model relates to the technical field of decorative plates, in particular to a composite decorative plate and a composite decorative module. Background Art

[0002] Decorative panels are divided into two types: exterior wall decorative panels and interior decorative panels. Due to the different indoor and outdoor environments, the performance of the two decorative panels is different and cannot be used interchangeably. At present, indoor decorative panels generally adopt a waterproof design, which is generally made of waterproof materials, such as silicate; this design relies on its internal waterproof layer or waterproof structure to achieve waterproofness as a whole, such as a decorative waterproof panel disclosed in the patent with publication number CN202936965U, which is waterproofed by setting a waterproof layer, wherein the waterproof layer is composed of one or more of waterproof grease, synthetic resin, rubber, plastic or modified asphalt. Since it is installed indoors as a whole, the waterproof layer composed of waterproof grease, synthetic resin, rubber, plastic or modified asphalt has a heavy smell, which is not conducive to environmental protection. At the same time, in the patent, it is indicated to set a simple three-layer structure, which lacks toughness as a whole, and the waterproof layer is easy to age. After being attached to the wall by adhesive in the later stage, it is easily affected by the seasonal environment, and cracking is prone to occur during the later use. Utility Model Content

[0003] In order to overcome one of the deficiencies of the prior art, the purpose of the present invention is to provide a composite decorative board and a composite decorative module, which have sufficient toughness and waterproofness and are suitable for use in indoor environments of different seasons.

[0006] Furthermore, the toughness layer is obtained by sequentially soaking sawdust or wood shavings in lime water, air-drying, vacuum drying, and hot-pressing and bonding with inorganic flexible adhesive.

[0007] Furthermore, the corrugated layer is composed of a plurality of corrugated modules, and the corrugations on two adjacent corrugated modules are staggered.

[0008] Furthermore, a clamping head and a clamping slot are respectively provided on the opposite end surfaces of the corrugated module, and two adjacent corrugated modules are connected with the clamping head through the clamping slot.

[0009] Furthermore, the intermediate layer is a calcium silicate-based layer or a metal mesh layer.

[0010] Furthermore, a PVC film is adhered to the outer side of the decorative surface layer.

[0011] Furthermore, the protective layer is composed of one or more of aluminum plastic, glass fiber, aluminum foil, and rubber.

[0012] Furthermore, it also includes a frame, the inner side of the frame is in contact with the middle layer, the toughness layer and the corrugated layer, and the edges of the protective layer and the decorative surface layer are both sealed on the frame and flush with the outer end surface of the frame.

[0013] Furthermore, a receiving groove is provided on the inner side surface of the frame, and the side edges of the intermediate layer, the toughness layer and the corrugated layer are all placed in the receiving groove and abut against the bottom of the receiving groove.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Reference Figures 1 to 3 The present invention provides a composite decorative module, including a composite decorative board; wherein the composite decorative modules can be spliced ​​with each other. The composite decorative board includes an intermediate layer 10; a tough layer 20 is provided on both sides of the intermediate layer 10, a corrugated layer 30 is provided on the outer side of the tough layer 20, a protective layer 40 is provided on the outer side of the corrugated layer 30, and a decorative surface layer 50 is provided on the outer side of the protective layer 40; a plurality of channels 60 are formed between the two sides of the corrugated layer 30 and the tough layer 20 and the protective layer 40, and the channels 60 are filled with glass fiber 70.

[0025] The channel 60 is naturally formed by the corrugations on the surface of the corrugated layer 30, and the glass fiber 70 is filled in the channel 60, which can further enhance the strength of the entire decorative board. At the same time, the glass fiber 70 has a certain toughness, so that the entire decorative board can undergo a certain deformation.

[0026] The composite decorative board and composite decorative module are provided with toughness layers 20 on both sides of the middle layer 10. The toughness layer 20 is used to improve the toughness of the entire board. The corrugated layer 30 can effectively reduce the overall thickness and also play a role in sound insulation and shock absorption. The protective layer 40 can effectively reduce the erosion of the board by external water vapor and air, and improve the protective effect. The decorative surface layer 50 can increase the decorative aesthetics. In addition, a number of channels 60 are formed between the toughness layer 20 and the protective layer 40. These channels 60 are filled with glass fibers 70, which can further improve the overall strength and toughness, adapt to the deformation of the wall, and thus achieve the function of anti-cracking. In addition, the tough layer 20 is made of sawdust or wood shavings that are sequentially soaked in lime water, dried, vacuum dried, and hot-pressed with an inorganic flexible adhesive. Therefore, it can absorb air and moisture that penetrate into the board. The calcium oxide in the sawdust or wood shavings reacts with carbon dioxide and moisture in the air to form calcium carbonate, which can harden the sawdust or wood shavings as a whole. This allows the entire tough layer 20 to not only have a certain ability to resist moisture and cracking, but also have toughness and strength.

[0027] Furthermore, in the above-mentioned embodiment, in order to improve the overall strength and have a certain moisture-proof function, the toughness layer 20 is obtained by soaking sawdust or wood shavings in lime water, drying, vacuum drying, and hot-pressing and bonding with inorganic flexible glue. Such a design makes full use of the reaction between calcium oxide and carbon dioxide and water in the air, and can absorb the air and water that penetrate into the decorative board to the greatest extent, avoiding the air and water from penetrating into it and precipitating and expanding to damage the board. At the same time, the wood fibers inside the sawdust or wood shavings themselves have a certain toughness, so even if calcium oxide reacts with carbon dioxide and water in the air to produce calcium carbonate, it still has a certain toughness, and calcium carbonate increases the strength of the sawdust or wood shavings themselves, thereby improving the overall strength of the entire toughness layer 20.

[0028] See also Figure 1 In one embodiment of the present application, in order to improve the overall strength and avoid the appearance of a single pattern, the corrugated layer 30 with patterns in different directions is composed of a plurality of corrugated modules, and the corrugations on two adjacent corrugated modules are staggered. Such an arrangement makes the directions of the channels 60 perpendicular to each other in different regions, and thus makes the glass fibers 70 in different regions also perpendicular to each other, thereby ensuring the strength of the entire board.

[0029] Furthermore, in order to facilitate the connection between two adjacent corrugated modules and improve the strength of the entire corrugated layer 30, the corrugated modules are provided with a clamp and a clamping groove on the opposite end faces, and the two adjacent corrugated modules are connected with the clamp through the clamping groove. Such a design enables each corrugated module to be connected to the adjacent corrugated module as a whole, thereby improving the overall connectivity.

[0030] See also Figure 2 In the present application, in order to maintain the entire decorative board with sufficient waterproofness, the intermediate layer 10 is a calcium silicate base layer; of course, in some embodiments, in order to improve toughness, the intermediate layer 10 can be a metal mesh layer. Such a design is used according to actual needs. In addition, in one embodiment of the present application, in order to improve the protection and prevent air and moisture from entering the interior of the entire decorative board, the protective layer 40 is composed of one or more of aluminum plastic, glass fiber, aluminum foil, and rubber. In an improved embodiment, in order to improve the protection of the decorative surface layer 50 and prevent the decorative surface layer 50 from being scratched, a PVC film 80 is adhered to the outer surface of the decorative surface layer 50.

[0031] See also Figure 3 In one embodiment of the application, in order to prevent air, moisture or other substances from entering the middle layer 10 and the tough layer 20 from the edge, the application also includes a frame 90, the inner side of the frame 90 is in contact with the middle layer 10, the tough layer 20 and the corrugated layer 30, and the edges of the protective layer 40 and the decorative surface layer 50 are both sealed on the frame 90 and flush with the outer end surface of the frame 90. Among them, the frame 90 is mainly used to seal the edges of the middle layer 10, the tough layer 20 and the corrugated layer 30, and the edges of the protective layer 40 and the decorative surface layer 50 are both sealed on the two sides of the frame 90. Such a design can effectively make the frame 90 and the protective layer 40 more closely connected, thereby improving the protection of the entire decorative board.

[0032] Furthermore, in the above-mentioned improved solution, in order to better connect the middle layer 10, the tough layer 20 and the corrugated layer 30, a receiving groove 91 is provided on the inner side of the frame 90, and the side edges of the middle layer 10, the tough layer 20 and the corrugated layer 30 are all placed in the receiving groove 91 and abut against the bottom of the receiving groove 91. This way, the frame 90 is more tightly connected to the outer surfaces of the corrugated layers 30 on both sides, and the frame 90 is prevented from being loosened.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
