Preferably, the concrete is ultrahigh-strength concrete, and the concrete structure layer is an ultrahigh-strength concrete structure layer, so that the concrete has better mechanical property and weather resistance. Concrete with a compressive strength grade of C100 and above is considered by the industry as ultra-high strength concrete. On one hand, the ultrahigh-strength concrete has high strength and high compactness, so that the fracture rate of the phase change energy storage particles can be reduced, and the phase change material in the phase change energy storage particles can be prevented from leaking even if the phase change energy storage particles are fractured; on the other hand, the ultrahigh-strength concrete has certain viscosity, cellulose ether does not need to be added to improve the viscosity, and the ultrahigh-strength concrete and the phase change energy storage particles are directly mixed, so that the phase change energy storage particles can be prevented from floating upwards, and the uniform dispersion of the ultrahigh-strength concrete in a concrete structure layer is further ensured. Preferably, the concrete structure layer is 3-8 mm.
Preferably, the phase change energy storage particles are phase change microcapsules. The interface layer is a net structure and is arranged on the concrete structure layer. The interface layer can enhance the strength of the concrete decorative plate, and further can reduce the thickness of the concrete decorative plate.

The example of the quartz sand of 20-40 meshes is the quartz sand with a sieving granularity, that is, the quartz sand with a particle size capable of passing through the sieve pores of a sieve with 20-40 meshes.
The decorative layer obtained by grading the raw materials of the decorative layer has high strength, and the cellulose ether can improve the binding power and the water retention performance among the components of the decorative layer, thereby playing the roles of preventing cracking and bleeding. In addition, the decorative layer and the concrete structure layer are solidified, connected and fastened, the problem that the decorative layer is easy to crack and peel off under the severe environment caused by different thermal expansion coefficients between layers is avoided, the strength of the concrete decorative plate is further improved, the breakage rate of the concrete decorative plate is reduced, the durability of the concrete decorative plate is further improved, the thickness of the concrete decorative plate is reduced, the later maintenance workload can be effectively reduced, and the cost is reduced.
More preferably, the raw materials of the decorative layer comprise, by weight, 350-500 parts of cement, 750-850 parts of 20-40 mesh quartz sand, 250-290 parts of 40-70 mesh quartz sand, 16-18 parts of a water reducing agent, 0.4-0.6 part of cellulose ether and 190-220 parts of water.

And secondly, the quartz sand with the three types of particle size ranges not only has good mechanical property, but also has low economic cost. More preferably, the 325-mesh quartz sand is 300-310 parts.
Preferably, the raw materials of the decorative layer comprise 2-8 parts by weight of phase change energy storage particles. Thus, the cold and heat resistance of the concrete decorative plate and the constant room temperature can be further enhanced. In addition, the graded decorative layer has high strength and high compactness, can reduce the fracture rate of the phase change energy storage particles, and can avoid the leakage of the phase change material in the phase change energy storage particles even if the phase change energy storage particles are fractured; and the cellulose ether in the decorative layer can improve the viscosity of the decorative layer, and then can prevent the phase change energy storage particles from floating upward, and ensure that the phase change energy storage particles are uniformly dispersed in the decorative layer. More preferably, the phase change energy storage particles are 3-5 parts. More preferably, the particle size range of the phase change energy storage particles is 20-40 meshes.
