Prefabricated decoration wall panel with efficient shading function

The invention discloses a prefabricated decoration wall panel with an efficient shading function, and belongs to the technical field of prefabricated buildings. The prefabricated decoration wall panelcomprises a wall panel body, wherein fixed bases are fixedly connected to both ends of one side of the wall panel body, a limiting mechanism is arranged on one side of each fixed base, support mechanisms are arranged at the bottoms of the fixed bases, shading mechanisms is arranged between the support mechanisms and a top fixed base, and a sound absorption plate is arranged between the fixed bases on the both sides. According to the prefabricated decoration wall panel, a shading curtain can be used for shading and blocking light, a first threaded column rotates so as to drive a moving block to move in a base, the moving block moves so as to pull a top shading plate to move into a U-shaped assembling plate, and the transparent assembling plate is blocked by a shading plate, so that external light can be further bl
