[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. The present invention forms an air layer between the PVC facing layer, the metal bracket and the magnesium oxychloride fireproof material. The air layer, as a poor conductor of heat, can significantly reduce the transfer of heat, so that the decorative panel can effectively maintain the indoor temperature and reduce heat loss or heat intrusion, which not only improves the comfort of living and working, but also helps to save energy and reduce energy consumption. At the same time, the air layer can also improve the noise reduction performance of the PVC decorative panel and effectively reduce its weight, thereby greatly optimizing the installation and transportation process. During installation, workers can operate more easily and improve work efficiency. During transportation, due to the reduction in weight, the load of the transportation vehicle can be reduced, the transportation cost can be reduced, and the safety risk during transportation can also be reduced. Therefore, the problem of how to simultaneously improve the heat insulation and noise reduction performance of the PVC decorative panel and reduce the weight of the PVC decorative panel to facilitate installation and transportation can be solved.

[0042] 2. The present invention installs gypsum board on the top of the upper magnesium oxychloride fireproof material and the bottom of the lower magnesium oxychloride fireproof material, and the gypsum board is located on the outside of the metal bracket. The addition of the gypsum board not only increases the overall thickness of the decorative panel, but also provides additional support for it. This support effect is combined with the metal bracket to form a more stable structural system, which can better resist deformation and damage regardless of external impact or internal stress changes, thereby maintaining the integrity and stability of the decorative panel, directly improving the safety of the PVC decorative panel. In extreme cases such as fire, the magnesium oxychloride fireproof material can effectively prevent the spread of fire, and the solid structure of the gypsum board and the metal bracket can prevent the decorative panel from deforming or collapsing in the fire, providing residents with a longer escape time. Therefore, it can solve the problem of how to enhance the structural stability of the PVC decorative panel, thereby improving the safety of the PVC decorative panel.

[0043] 3. The present invention adheres a reflective film on the surface of the PVC facing layer. The reflective film has the characteristic of reflecting light in a weak light environment. When an external light source irradiates the reflective film on the PVC facing panel, the film surface can reflect bright light, so that the facing panel is still clearly visible in an environment with insufficient light. This characteristic makes the PVC facing panel more conspicuous at night or in a dim indoor environment, can significantly reduce collision accidents caused by poor vision, and improve people's walking safety. In addition to improving visibility, the reflective film can also add a unique beautifying and decorative effect to the PVC facing panel. Under the irradiation of light, the reflective film can present a gorgeous luster and color, making the facing panel more beautiful and generous, which not only enhances the overall visual effect of the building, but also brings people a more comfortable and pleasant visual experience. Therefore, the problem of how to improve the visibility of the PVC facing panel in an environment with insufficient light can be solved, thereby reminding people to pay attention and avoid collisions.

[0044] 4. The present invention performs edge treatment on the main body of the PVC decorative panel. The edge treatment can eliminate burrs and unevenness on the edges of the PVC decorative panel, making the appearance of the entire PVC decorative panel smoother and neater. The edges of untreated PVC decorative panels are easily eroded by the external environment, including the infiltration of moisture and dust, which leads to damage and aging of the PVC decorative panels. The PVC decorative panels that have undergone edge treatment can effectively resist these erosions and maintain their stability and durability. In addition, the edge treatment can also enhance the structural strength of the PVC decorative panels, improve their impact resistance and deformation resistance, and further extend their service life. Therefore, it can solve the problem of how to improve the aesthetics of the PVC decorative panels and extend the service life of the PVC decorative panels. DETAILED DESCRIPTION

[0054] Step S13: Use a grinder and sandpaper to perform preliminary grinding on the surface of the solid wood board base to remove burrs, unevenness, stains and impurities. Then, based on the preliminary grinding, use finer sandpaper and a polisher for fine grinding. After grinding, use a clean cloth and a vacuum cleaner to remove dust and grinding residues on the surface of the solid wood board base.

[0055] Further, use a soft brush and vacuum cleaner to remove dust, sawdust and other large particles of impurities on the top and bottom of the solid wood board substrate, which can ensure that the surface of the solid wood board substrate is clean and there are no impurities that affect the subsequent processing and painting effects. Pour wood cleaner on a clean cloth and wipe the surface of the solid wood board substrate evenly to remove stubborn stains or oil stains. The solid wood board substrate can be deeply cleaned to remove stains that are not easily washed off by water. Use clean water and a clean cloth to wipe the solid wood board substrate again to remove residual detergent. Ensure that there is no detergent residue on the surface of the solid wood board substrate to avoid affecting the subsequent primer adhesion. Place the cleaned solid wood board substrate in a ventilated environment to dry naturally, ensure that the solid wood board substrate is completely dry, and avoid uneven painting and bubbling caused by moisture;

[0056] Place the naturally dried solid wood base on a flat and stable table to ensure that the solid wood base is in a horizontal state so as to accurately check its flatness. Perform a preliminary visual inspection to observe whether there are bumps, ripples and creases on the top and bottom of the solid wood base. This can quickly reveal obvious flatness problems. Use a ruler, level and laser rangefinder to measure the top and bottom of the solid wood base. These tools can provide more accurate data to help determine whether the flatness of the base meets the requirements.

[0057] Use a grinder and sandpaper to perform preliminary grinding on the surface of the solid wood board base to remove burrs, uneven parts, stubborn stains and impurities on the surface. Based on the preliminary grinding, use finer sandpaper and polishing machine for fine grinding to further improve the smoothness and flatness of the surface of the solid wood board base, providing a better foundation for subsequent painting work. After grinding, use a clean cloth and vacuum cleaner to remove dust and grinding residues on the surface of the solid wood board base to ensure that the surface of the solid wood board base is clean and dust-free so that the subsequent primer can adhere evenly.

[0058] Embodiment 2:

[0059] A method for preparing a PVC decorative panel with good fire resistance, the method for preparing the PVC decorative panel is as follows:

[0060] Step S2, applying primer and aluminum ammonium phosphate flame retardant on the surface of the solid wood board base;

[0061] Step S2 also includes the following steps:

[0062] Step S21: After the primer is mixed with the primer thinner and the primer curing agent and stirred evenly, the primer is evenly applied to the surface of the solid wood board base using a roller, and then the primer is allowed to dry naturally under the conditions of a temperature of 22° C. and a humidity of 58%. After drying, check whether the primer is even and smooth, and perform repairs and repainting if there are any flaws or defects;

[0063] Step S22: Use a roller to evenly apply the aluminum ammonium phosphate flame retardant on the surface of the solid wood board base. After the initial application, place the solid wood board base in a natural environment to dry and cure. After the aluminum ammonium phosphate flame retardant is completely dried and cured, check whether the aluminum ammonium phosphate flame retardant coating has omissions and bubbles. If there are omissions and bubbles, use a roller for local trimming. After the initial coating is dried and cured, apply the next layer in the same way. Repeat the application process 5 times. After all coatings are dried and cured, conduct a final inspection of the solid wood board base.

[0064] Further, the primer is mixed with the primer thinner and the primer curing agent in a certain proportion. The role of the primer thinner is to adjust the viscosity of the primer to make it easier to apply, and the primer curing agent can enhance the adhesion and durability of the primer. Use a stirring tool to stir the mixture evenly to ensure that the various ingredients are fully integrated to achieve the best application effect. Use a roller to evenly apply the primer on the surface of the solid wood base. The use of a roller can ensure that the primer is evenly applied to avoid uneven thickness. During the application process, pay attention to controlling the strength and speed of the roller to ensure that the primer can fully penetrate into the texture of the base to form a uniform coating.

[0065] Place the solid wood base with primer on it at 22℃ and 58% humidity to dry naturally. This temperature and humidity condition helps the primer to dry evenly and avoid cracking or blistering. After drying, carefully check whether the primer coating is even and smooth. If there are flaws and defects, such as uneven coating or bubbles, use a roller to repair and re-coat.

[0066] Then use a roller to evenly apply the aluminum ammonium phosphate flame retardant on the surface of the solid wood board base. The application of the flame retardant can significantly improve the fire resistance of the solid wood board base. During the application process, pay attention to controlling the amount and thickness of the flame retardant to ensure that the coating is uniform and not too thick, so as not to affect the air permeability and aesthetics of the base. After the initial application, place the solid wood board base in a natural environment to dry and cure. The drying and curing process of the flame retardant takes a certain amount of time. During this period, avoid direct sunlight and high-temperature baking to avoid affecting the performance of the flame retardant.

[0067] After the flame retardant is completely dry and cured, carefully check the coating for omissions and bubbles. If these problems exist, use a roller for local trimming to ensure that the coating is complete and flat. Apply the next layer in the same way and repeat the application process 5 times. Multi-layer application can further improve the fireproof effect of the flame retardant and enhance the safety of the base layer. After all coatings are dry and cured, conduct a final inspection of the solid wood base layer to ensure that the flame retardant coating is uniform, complete and flawless.
