Abstract

The utility model discloses a sound-absorbing decorative board, which comprises a perforated glass magnesium board, centrifugal glass wool and glass silk cloth. The centrifugal glass wool is attached to the inner side of the perforated glass magnesium board, and the glass silk cloth is attached to the outer surface of the perforated glass magnesium board. The sound-absorbing decorative board has high seismic strength and also has a decorative effect.

Description

Acoustic decorative panel

technical field

The utility model relates to decorative materials, in particular to a sound-absorbing decorative board.

Background technique

With the continuous improvement of people's living standards, the requirements for the acoustic environment are getting higher and higher. At present, the noise generated by vehicles, highways, railways, machinery, etc. has a great impact on the surrounding environment. The solution is to use soft polyurethane foam to foam and absorb sound in the cavity. The sound absorption effect is good, but the strength is low and there is no Decorative effect.

The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and should not be considered as an acknowledgment or in any form to imply that the information constitutes the prior art already known to those skilled in the art.

Utility model content

The purpose of the utility model is to provide a sound-absorbing decorative board, which has high shock resistance and has a decorative effect.

In order to achieve the above purpose, the utility model provides a sound-absorbing decorative panel, including a perforated glass magnesium board, centrifugal glass wool and glass cloth, the centrifugal glass wool is attached to the inner side of the perforated glass magnesium board, and the glass cloth is attached to the perforated glass magnesium board. outside surface of the board.

Compared with the prior art, the utility model has the following beneficial effects: the structure of the sound-absorbing decorative board is composed of perforated glass magnesium board, centrifugal glass wool and glass silk cloth, the seismic intensity reaches grade 9, and the sound-absorbing and noise-reducing index is relatively high. The facing layer has a decorative effect, and different colors and texture patterns can be drawn according to requirements.

detailed description

The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

As shown in Figures 1 to 2, a sound-absorbing decorative panel according to a specific embodiment of the present invention includes a perforated glass magnesium board 1, centrifugal glass wool 2 and glass silk cloth 3, wherein the centrifugal glass wool 2 is pasted on the perforated glass On the inner side of the magnesium board 1 , the glass cloth 3 is attached to the outer surface of the perforated glass magnesium board 1 .

In the above scheme, the glass magnesium board that makes up the sound-absorbing decorative board is light in weight, high in strength compared to the same period, and the seismic intensity reaches level 9, which improves heat preservation and flame retardancy, wide sound-absorbing frequency, and is easy to install. According to different frequencies, by adjusting the opening ratio of the perforated glass magnesium board and the thickness of the perforated board (during construction, the thickness of the centrifugal glass wool filled inside determines the sound absorption effect), different noise reduction requirements of customers can be realized. Centrifugal glass wool is a porous sound-absorbing material with good sound-absorbing properties. The reason for its ability to absorb sound is mainly because it has a large number of tiny pores connected internally and externally. When the sound wave is incident on the centrifugal glass wool, the sound wave can enter the interior of the material along the pores, causing the vibration of the air molecules in the pores. Due to the viscous resistance of the air and the friction between the air molecules and the pore wall, the sound energy is converted into heat energy and lost. The noise reduction coefficient can reach above 0.85. In addition, the glass silk cloth 3 is used as a decorative surface layer, and different colors and texture patterns can be drawn according to requirements, which has a decorative effect. A sound-absorbing decorative panel is provided, with better sound-absorbing and noise-reducing indicators;

To sum up, the sound-absorbing decorative panel of this embodiment is composed of perforated glass magnesium board, centrifugal glass wool and glass silk cloth. It is required to draw different color and texture patterns.

The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. These descriptions are not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various exemplary embodiments of the present invention and various Different options and changes. It is intended that the scope of the invention be defined by the claims and their equivalents.
