[0002] Perforated gypsum board refers to a gypsum board with cylindrical holes running through the front and back of the gypsum board, which is composed of a combination of a breathable backing material and a sound-absorbing material that can absorb incident sound energy. In the process of house decoration, in order to create a better indoor environment, it is necessary to use perforated gypsum board to soundproof and absorb the indoor sound. When using the existing perforated gypsum board, the sound insulation board needs to be bonded to the gypsum board, which can easily cause the two to fall off. For example, as shown in a perforated gypsum board for sound absorption and sound insulation with Chinese patent application number CN202321333444.8, the gypsum board, the sound insulation board and the sound-absorbing cotton are bonded and connected to achieve sound absorption on the roof of the house.

[0003] However, since the gypsum board, sound insulation board and sound-absorbing cotton are bonded together, when the gypsum board is used for a long time, the glue bonding the gypsum board, sound insulation board and sound-absorbing cotton will lose its viscosity and cause the three to fall off, which will affect the sound absorption and sound insulation effect of the gypsum board.
