As shown in fig. 1-3, the present embodiment provides a perforated sound absorption porcelain steel plate, which includes a sound absorption plate 100, a plurality of sound absorption holes 110 are provided on the sound absorption plate 100, the size and the distance of the sound absorption holes 110 are adjusted according to actual needs, the periphery of the sound absorption plate 100 is folded towards the same side to enclose a containing cavity 120, a sound absorption member 200 is fixedly filled in the containing cavity 120, and a waterproof and breathable film 300 covers the side of the sound absorption member 200 away from the sound absorption plate 100.

The sound absorption plate 100 can be attached to a wall body to have a decoration effect, and the sound absorption piece 200 in the sound absorption plate 100 can absorb indoor noise of a building, so that indoor echoes can be reduced, and influence on the external environment can be avoided.

As another preferred embodiment, the sound-absorbing panel 100 is made of a steel plate, the sound-absorbing panel 100 is made by stamping, the sound-absorbing holes 110 are formed by punching, and the front surface of the sound-absorbing panel 100 is coated with a water-based inorganic ceramic coating to form a ceramic film. The porcelain film enables the surface of the sound absorption plate 100 to have excellent physical properties such as good porcelain jade texture, A1-grade fire resistance, 9H pencil hardness, good scratch resistance, dirt resistance, aging resistance and the like. The steel plate with the ceramic film is not only firm and durable, but also beautiful and has obvious decorative effect. Further, a frosted layer is provided on the surface of the sound-absorbing panel 100 and formed by a rubbing process. The frosted layer can improve the adhesion capability of the coating.
