Inorganic metal sound-absorption composite board

Abstract

The invention discloses an inorganic metal sound-absorbing composite board, which comprises a glass magnesium board. Aluminum foil and an aluminum board A are respectively arranged on the upper and lower sides of the glass magnesium board. A PVC decorative film is arranged on the upper side of the aluminum foil. The holes are distributed in a rectangular shape and correspond to the up and down sound-absorbing grooves on the glass magnesium board. Aluminum board B is placed under aluminum board A. The outer edge of aluminum board A is bent downward by 90°, and the outer edge of aluminum board B is bent upward by 90°. , and the outer edge of the aluminum plate A is connected by a self-locking mechanism, and a cavity is formed between the aluminum plate A and the aluminum plate B. The invention utilizes connecting rods to enhance the connection strength between the glass magnesium board and the aluminum board A, and a self-locking mechanism is provided between the aluminum board A and the aluminum board B, which is convenient for assembly, stable in structure and good in noise reduction effect. The invention has the properties of high strength, sound absorption and noise reduction, fire prevention, moisture resistance, environmental protection and the like. The invention has novel and reasonable structure, convenient use and suitable popularization.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and particularly relates to an inorganic metal sound-absorbing composite board. Background technique [0002] At present, there are many kinds of architectural decorative panels on the market. In many public places such as concert halls, theaters, dance halls, KTV rooms, conference rooms, lecture halls, etc., sound absorption and noise reduction are an important reference index for architectural decorative panels. In addition, the board also needs to have good strength, fire resistance, moisture resistance, environmental protection and other properties, and the existing decorative boards are difficult to achieve. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies in the background technology, the present invention provides an inorganic metal sound-absorbing composite board with the characteristics of high strength, sound absorption and noise reduction, fire preve...
