[0014] The following further details the specific embodiments of the utility model with reference to the drawings.

[0015] It is given by Figure 1 including a bottom layer, with a middle layer provided on the upper side of the bottom layer, and a surface layer provided on the upper side of the middle layer. The bottom layer has three layers, including an adhesion layer 1, with a crack resistance layer 2 provided at the upper end of the adhesion layer 1, and a reinforcement layer 3 provided on the upper side of the crack resistance layer 2. The middle layer has five layers, including a cement layer 4, with a grid layer 5 provided at the upper end of the cement layer 4, a sound insulation layer 6 provided at the upper end of the grid layer 5, a heat preservation layer 7 provided at the upper end of the sound insulation layer 6, and a waterproof layer 8 provided at the upper end of the heat preservation layer 7. The surface layer has one layer, including a decorative wear-resistant layer 9.

[0016] As Figure 1 shown, the bottom layer is provided for contacting the base layer, and it needs to have strong adhesion and crack resistance to ensure that there are no problems of cracking and hollowing in the bottom layer, resulting in peeling, laying a good foundation. At the same time, the reinforcement layer 3 can play the role of strengthening the bottom layer and connecting the middle layer. The middle layer is mostly a functional coating. Among them, the grid layer 5 can improve the overall stability and reinforce the plastering coating. The sound insulation layer 6, the heat preservation layer 7 and the waterproof layer 8 can play the roles of sound insulation, heat preservation and waterproofing, improving the overall functionality and practicability. The surface layer can play the role of wear resistance, reducing the surface damage rate and at the same time reducing the maintenance cost.

[0017] The material of the adhesion layer 1 is modified polymer mortar, and the adhesion layer 1 contains polyvinyl alcohol fibers. The material of the crack resistance layer 2 is paper pulp lime mortar, and the crack resistance layer 2 contains paper pulp lime. The material of the reinforcement layer 3 is acrylate glue mortar, and the reinforcement layer 3 contains acrylate glue powder.

[0018] As Figure 1As shown, the material of the adhesion layer 1 is modified polymer mortar. Polyvinyl alcohol fibers are added to the mortar to improve its adhesiveness, ensuring good bonding with the base layer and avoiding the problem of hollowing. The anti-cracking layer 2 is made of paper pulp lime mortar, which can improve the overall anti-cracking property of the mortar. It can increase the connection strength and consistency of the mortar, avoiding the problem of cracking on the plaster surface. The reinforcement layer 3 is made of acrylate glue mortar. Acrylate glue powder can improve the bonding strength between the mortar and the substrate, reducing the possibility of peeling or separation, playing a reinforcement role. And compared with traditional mortar, acrylate glue mortar usually has a faster curing speed, which helps to shorten the construction period. The bottom three layers all have good adhesiveness, anti-cracking and anti-impact properties, and can be well combined with the base layer to lay a good foundation.

[0019] The material of the cement layer 4 is inorganic polymer mortar. The cement layer 4 contains lightweight aggregates. The material of the mesh layer 5 is fiberglass mesh. The material of the sound insulation layer 6 is polystyrene mortar. The sound insulation layer 6 contains polystyrene foam particles. The material of the thermal insulation layer 7 is expanded perlite mortar. The thermal insulation layer 7 contains expanded perlite. The material of the waterproof layer 8 is silicate mortar. The waterproof layer 8 contains silicate waterproofing agent.

[0020] As Figure 1 shown, the material of the cement layer 4 is set as inorganic polymer mortar. It has environmental friendliness because it uses inorganic components and usually does not contain organic solvents, meeting the environmental protection requirements. And it has good adhesiveness and can be used for hanging nets and connecting with the bottom layer. Therefore, the cement layer 4 plays a good role in connecting and transitioning. Setting the mesh layer 5 can fix the whole with fiberglass mesh, improving the overall stability and not being easy to fall off. Setting the sound insulation layer 6 and the thermal insulation layer 7 can achieve the effects of sound insulation and heat insulation. The expanded perlite in the thermal insulation layer 7 can be replaced with ceramsite or foam glass, etc., and still can achieve the heat insulation effect. The waterproof layer 8 is silicate mortar, which can effectively resist water penetration, reduce the impact of moisture on the building. At the same time, it has frost resistance and can be used in cold regions to resist the impact of freeze-thaw cycles.

[0021] The material of the decorative wear-resistant layer 9 is polyurethane mortar. The decorative wear-resistant layer 9 contains polyurethane emulsion.

[0022] As Figure 1 shown, setting the material of the decorative wear-resistant layer 9 as polyurethane mortar has good wear resistance and anti-impact properties. As the surface layer, it can play a good protective role and is also convenient for repair.

[0023] The thicknesses of both the adhesion layer 1 and the anti-cracking layer 2 are 3mm, and the thickness of the reinforcement layer 3 is 1mm - 1.5mm.

[0024] As Figure 1As shown, the relatively thick thicknesses of the adhesion layer 1 and the crack-resistant layer 2 can achieve the purpose of well flattening the pits. The thickness of the reinforcement layer 3 is set to be relatively thin. Since both the adhesion layer 1 and the crack-resistant layer 2 have good crack resistance and adhesiveness, the reinforcement layer 3 only plays an auxiliary role and does not need to be too thick.

[0025] The thickness of the cement layer 4 is 3 mm, the thickness of the grid layer 5 is 0.5 mm - 1 mm, the thickness of the sound insulation layer 6 is 2 mm, the thickness of the thermal insulation layer 7 is 3 mm, and the thickness of the waterproof layer 8 is 2 mm.

[0026] As Figure 1 shown, setting the cement layer 4 to be relatively thick can achieve the purpose of connection and facilitating net hanging, and the thicknesses of the other coatings can be changed according to requirements.

[0027] The thickness of the decorative wear-resistant layer 9 is 1.5 mm.

[0028] As Figure 1 shown, the surface layer thickness does not need to be too thick and can play a protective role.

[0029] When the present utility model is in use, check the flatness, dryness and strength of the wall base to be plastered, remove the dust, oil stains and loose particles on the surface. For the base with strong water absorption, water it in advance and keep it moist but not waterlogged to complete the preparatory work before plastering;

[0030] Subsequently, configure the mortar coatings of each layer according to requirements. After completion of the configuration, perform plastering in layers. First, spread the bottom mortar evenly on the base surface and let it stand still until it hardens to ensure good adhesion to the base. Subsequently, apply the middle layer mortar successively. First, after applying the cement layer 4 and before it hardens, use fiberglass mesh to hang the net for the whole, and then continue to apply the sound insulation layer 6, the thermal insulation layer 7 and the waterproof layer 8;

[0031] After completion, the surface mortar can be applied. After application, it is necessary to level it to ensure the surface is flat. After completion, perform maintenance according to requirements. After the construction is completed, conduct a secondary inspection of the surface to ensure there are no omissions.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art of the present utility model can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
