Acoustic cellular board

Abstract

The invention relates to an acoustic cellular board. The acoustic cellular board is characterized by comprising a middle main cellular board body, wherein a microporous acoustic board is arranged on one side of the main cellular board body, a bottom plate is arranged on the other side of the main cellular board body, first acoustic paper is arranged between the main cellular board body and the bottom plate, a first glue layer and a second glue layer are arranged on two side surfaces of the first acoustic paper respectively, second acoustic paper is arranged between the main cellular board bodyand the microporous acoustic board, and a third glue layer is arranged on the side, connected with the main cellular board body, of the second acoustic paper. The acoustic cellular board has the advantages that holes cannot be blocked after spraying, the sound absorbing performance is guaranteed, color difference is avoided, and attractiveness is guaranteed.

Description

technical field [0001] The invention relates to a sound-absorbing honeycomb panel. Background technique [0002] With the improvement of the national economy, in order to improve the comfort in the room, sound-absorbing panels gradually appeared on the market. The sound-absorbing panel is an ideal sound-absorbing decoration material. It has the advantages of sound absorption, environmental protection, flame retardant, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, mosaic, simple construction, good stability, good impact resistance, good independence, and high cost performance. A variety of colors are available to meet the needs of different styles and levels of sound-absorbing decoration. [0003] In order to increase the aesthetic effect, powder spraying is carried out on both surfaces of the sound-absorbing panel. However, due to the micropores on the sound-absorbing panel, after powder spraying, plugged holes...

AI Technical Summary

Problems solved by technology

[0003] In order to increase the aesthetic effect, powder spraying is carried out on both surfaces of the sound-absorbing panel. However, due to the micropores on the sound-absorbing panel, after powder spraying, plugged holes are formed in the micropores, which affects the sound-absorbing effect of the sound-absorbing panel. It will cause the color difference problem of the decorative surface of the sound-absorbing panel

[0004] In addition, due to the needs of use, there are many sound-absorbing honeycomb panels on the market. The sound-absorbing honeycomb panels are made of thinner microporous sound-absorbing panels on both sides and the bottom plate are firmly bonded to a thicker honeycomb material. The main body of the honeycomb panel, the honeycomb structure in the middle greatly reduces the weight of the panel, but the bending stiffness is still high, making it light in weight and high in strength. It is widely used in large vehicles with lightweight requirements, such as It is used to make interior panels of vehicles, but because the glue is easy to overflow from the pores of the microporous sound-absorbing panel when the sound-absorbing panel and the main body of the honeycomb panel are bonded, one conveniently affects the aesthetic performance of the sound-absorbing honeycomb panel on the sound-absorbing surface, and the other On the one hand, because the glue fills the pores of the microporous sound-absorbing panel, the sound-absorbing effect is reduced
