Problems solved by technology

[0002] Nowadays, noise pollution has become a major source of harm to people's physical and mental health. Noise can affect people's hearing, causing hearing damage, headaches and other negative effects. Therefore, people have higher and higher requirements for the sound-absorbing effect of the building environment in which they live, so it is necessary to design a sound-absorbing material that can absorb incident sound waves highly effectively

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, a sound-absorbing panel includes a frame 1, a sound-absorbing layer and a non-woven fabric 4. The sound-absorbing layer includes a centrifugal glass wool layer 3 and a rock wool layer 2 from top to bottom. The centrifugal glass wool layer 3 has superior sound-absorbing properties. The rock wool layer 2 has excellent sound insulation and sound absorption characteristics, and the mutual cooperation of the two makes the sound-absorbing panel have a strong sound-absorbing effect. The centrifugal glass wool layer 3 and the rock wool layer 2 are bonded together through the glue layer, and the operation is simple. The material is cheap and the production cost is saved. The non-woven fabric 4 is arranged on the upper side of the centrifugal glass wool layer 3, that is, between the centrifugal glass wool layer 3 and the upper frame, and the non...

Abstract

The invention discloses a sound-absorbing board which comprises a frame, a sound absorption layer and non-woven cloth, wherein the sound absorption layer sequentially comprises a centrifugal glass cotton layer and a rock cotton layer from top down; the sound absorption layer is surrounded by the frame; the non-woven cloth is arranged on the upper side of the centrifugal glass cotton layer and the lower side of the rock cotton layer; and the frame is made of a density board with round holes in front and rear surfaces. According to the sound-absorbing board, the centrifugal glass cotton layer and the rock cotton layer which both have good sound-absorbing effect cooperate with each other, so that the sound-absorbing board is better in sound-absorbing property; meanwhile, the frame adopts the density board with the round holes in the front and rear surfaces, so that the sound-absorbing property of the sound-absorbing board is further improved; and the sound-absorbing board has good sound-absorbing effect and is worthy of popularization.

Description

technical field [0001] The invention relates to a board, in particular to a board with enhanced sound absorption effect. Background technique [0002] Nowadays, noise pollution has become a major source of harm to people's physical and mental health. Noise can affect people's hearing, causing hearing damage, headaches and other negative effects. Therefore, people have higher and higher requirements for the sound-absorbing effect of the building environment in which they live, so it is necessary to design a sound-absorbing material that can absorb incident sound waves highly effectively. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a sound-absorbing panel. The centrifugal glass wool layer has excellent sound-absorbing characteristics, and the rock wool layer has excellent sound-insulating and sound-absorbing characteristics. The mutual cooperation of the two makes the sound-absorbing panel have ...
