The protective layer 1 is used to protect the outer wall of the reinforcement layer 2, while improving the overall structural strength of the sound insulation building board and playing a heat insulation role.

[0038] The reinforcing layer 2 can be a mixture of cement, water, aggregates and additives. The cement can be, for example, silicate cement, which has the advantages of high strength and not prone to shrinkage cracks during the hardening process. During the mixing and stirring process, a number of foamed particles 5 and a number of first fibers 6 are also mixed in. Then the mixed mortar is injected into the accommodation gap 4 between the two protective layers 1. After solidification and hardening, it is bonded to the two protective layers 1.

In addition to having waterproof properties, the dense closed bubbles inside the structure of the waterproof layer 31 also have a sound insulation effect. The sound insulation layer 32 mainly plays a sound insulation role. The sound insulation layer 32 can be a plate formed by hot pressing of polyester fiber, glass fiber or rock wool, or a plate formed by hot pressing of cross-linked polyethylene IXPE or ethylene-vinyl acetate copolymer EVA, such as Figure 3 As shown, the two sides of the two waterproof layers 31 can be connected respectively to prevent the liquid of the mixed mortar of the reinforcement layer 2 from penetrating.
