[0021] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] The traditional acrylic decorative board is to directly bond the acrylic board to the wrapping paper 3, which will produce bubbles, rot and other undesirable phenomena at the bonding point, and the wrapping paper 3 will also cause the pattern to be worn, corroded and destroyed. In order to protect the wrapping paper 3 without affecting the decorative effect, an acrylic composite decorative board is designed, such as Figure 1 As shown, it includes three layers of materials, namely, a top layer, an interlayer and a bottom layer, and the three layers of materials are bonded together by an adhesive. The interlayer is a wrapping paper 3 with a pattern, the top layer is a first acrylic plate 1, and the bottom layer is a second acrylic plate 2. A casting cavity 4 is formed between the first acrylic plate 1 and the second acrylic plate 2, and the wrapping paper 3 impregnated with the adhesive is placed in the casting cavity 4. The depth of the casting cavity 4 is generally 3-6 mm, preferably 4 mm, which can not only ensure the polymerization strength of the first acrylic plate 1 and the second acrylic plate 2, but also ensure the clarity of the wrapping paper 3. The wrapping paper 3 is buried between the top layer and the bottom layer, which can effectively protect it from wear and tear, and the combination of the double acrylic plate and the acrylic polymer glue can avoid the generation of bubbles, ensure transparency, and ensure the decorative effect of the composite board.

[0023] In order to ensure the sealing effect and prevent bubbles, the wrapping paper 3 is made of high temperature resistant material. Preferably, the wrapping paper 3 is PET paper with UV printed patterns. PET still maintains good thermal stability at high temperatures and can be used as a sealing or heat sealing filler.

[0024] like Figure 2 As shown, the first acrylic sheet 1 and the second acrylic sheet 2 both include a bonding portion 11 and a cutting portion 12, and the cutting portion 12 is arranged outside the bonding portion 11. The wrapping paper 3 is placed at the bonding portion 11, and after pouring and curing, the cutting portion 12 needs to be cut off, and the middle portion with the wrapping paper 3 is retained.

[0025] like Figure 3 and 4As shown, a support layer is further provided between the first acrylic plate 1 and the second acrylic plate 2. The support layer is a rubber strip 5 arranged between the cutting portions 12 of the first acrylic plate 1 and the second acrylic plate 2, and the surrounding rubber strip 5 forms a casting cavity 4. During preparation, the second acrylic plate 2 is horizontally placed on a workbench, and then the rubber strip 5 is arranged around the upper surface of the second acrylic plate 2, the wrapping paper 3 is placed in the surrounding rubber strip 5, and then the first acrylic plate 1 is placed to compact the rubber strip 5 to form a closed casting cavity 4. In order to prevent the relative position of the first acrylic plate 1 and the second acrylic plate 2 from moving, a positioning can be applied above the cut portion 12 on the periphery of the first acrylic plate 1, and then the injection material can be injected into the casting cavity 4 through the gap between the acrylic plate and the rubber strip 5 using an injection needle. The first acrylic plate 1 can also be lifted up with a thin sheet, and then the injection hose can be inserted into the gap between the acrylic plate and the rubber strip 5 to facilitate injection. After the wrapping paper 3 is completely impregnated as can be seen with the naked eye, the injection is stopped. After the casting material is completely solidified, the cut portion 12 is cut off and the middle adhesive portion 11 is retained. The production of the composite decorative board is completed, and the pattern is clear and can be preserved for a long time.

[0026] A light groove 6 for burying a light bar is also provided on the side of the first acrylic plate 1 or the second acrylic plate 2 close to the interlayer. The light groove 6 is provided to facilitate the setting of the light bar, and the light bar and the wrapping paper 3 can be embedded between the first acrylic plate 1 or the second acrylic plate 2 together, so that when the ambient brightness is low, the light bar in the light bar groove can be turned on to increase the brightness, irradiate the wrapping paper 3, and achieve a corresponding decorative effect.

[0027] The adhesive is an acrylic body high-strength polymer glue, and the adhesive is filled in the casting cavity 4. Specifically, refer to the invention patent with announcement number CN114806465B, an acrylic body high-strength polymer glue, the weight ratio of the acrylic body polymer glue includes: 15-25 parts of acrylic acid, 5-10 parts of methyl methacrylate, 3-8 parts of isophthalic resin, 2-7 parts of water-based nano-silicon dioxide, 2-5 parts of rubber, 0.5-1.5 parts of anti-shrinkage agent, 0.3-0.6 parts of tackifier, 0.8-1.6 parts of room temperature curing agent. Among them, the anti-shrinkage agent is a mixture of polyacrylate, benzoxazine resin and modified nano-titanium dioxide, the room temperature curing agent is one or more of aliphatic polyamine, alicyclic polyamine, and low molecular weight polyamide, the tackifier is hydrogenated resin, and the hydrogenated resin is colorless transparent granular fully hydrogenated rosin resin. The nano-titanium dioxide in the anti-shrinkage agent has a high affinity with methyl methacrylate and isophthalic resin, which is conducive to the filling of nano-titanium dioxide particles, and improves the bonding strength between methyl methacrylate and isophthalic resin, improves the structural density, and thus improves the adhesion of the acrylic body. Embodiments 1-3 in the above patent document can all be used to polymerize the first acrylic sheet 1 and the second acrylic sheet 2, and embodiment 2 is preferred, which has the best bonding strength.
