Problems solved by technology

[0002] The traditional sandstone sound-absorbing panels of silicon crystal sand use natural sand to polymerize with inorganic binders to produce many invisible natural gaps of different sizes, which make them have good acoustic effects, and resonate with sound without generating noise. When used for surface decoration, it can also achieve seamless splicing, so it has good decoration and sound absorption effects. At the same time, it has A-class fire resistance and E1 environmental protection performance. Unsatisfactory, the scope of use is greatly limited
[0003] In contrast, metal perforated panels also have excellent fire resistance and environmental protection performance, and the material can be used for decoration such as arcs and other complex shapes, but because there are many holes on the surface, it affects its interior decoration effect. In acoustics, the sound and the metal plate resonate to produce noise, which interferes with the acoustic effect

Abstract

The invention discloses a metal perforated acoustic board, and belongs to the field of material machining and preparation. According to the metal perforated acoustic board, through combination of a metal perforated board material and a siliceous rock sandstone acoustic material, the metal perforated acoustic board has good bending performance, and meanwhile the acoustic absorption effect and the decoration effect of the material are greatly improved; and the two layers of materials in the metal perforated acoustic board are tightly and stably combined and connected, the phenomenon of falling or powder falling is avoided, and then composite machining can be conducted or the metal perforated acoustic board can be directly used in the fields of building materials or decorative materials. In addition, the product has few volatile substances, is environment-friendly, and also has excellent fireproof performance. The invention further discloses a preparation method of the metal perforated acoustic board. The method is simple in operation step and low in requirement for preparation instruments, and industrial large-scale production can be achieved. The invention further discloses application of the metal perforated acoustic board in decoration machining.
