Problems solved by technology

However, the sound-absorbing panels in the prior art are mainly made of low-quality chemical materials, which have a large degree of pollution to the room, are not environmentally friendly, and the formaldehyde content is easy to exceed the standard. The machinable strength is low, the scrap rate is high, and the structural strength at the opening or cutout is poor, which affects the local sound absorption performance of the sound-absorbing panel
Moreover, the existing sound-absorbing panels have potential safety hazards in terms of flame retardancy, and the amount of smoke emitted after a fire is relatively large, which can easily make people's breathing difficult

Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0012] This case proposes a high-life sound-absorbing panel, which at least includes a combination of polyester fiber, phenolic resin, polyamide resin and pine wood chips. Among them, phenolic resin and polyamide resin are used to improve the structural strength and toughness of polyester fiber, and at the same time help to increase the sound absorption coefficient of the sound-absorbing board; pine wood chips can improve the sound-absorbing performance of the sound-absorbing board, and at the same time help to reduce the weight of the board.

[0013] In the above embodiments, preferably, in parts by weight, 100 parts of polyester fiber, 10-15 parts of phenolic resin, 20-25 parts of polyamide resin, and 8-10 parts of pine wood chips. At this ratio, the performance of the acoustic panel...

Abstract

The invention discloses a sound absorption plate with a long service life. The sound absorption plate at least comprises combinations of polyester fibers, phenolic resin, polyamide resin and pine sawdust. The sound absorption plate has the advantages that components of materials for the sound absorption plate are improved, so that the sound absorption performance of the sound absorption plate can be regulated and improved; the materials are environmentally friendly, are free of pollution and are harmless to human bodies; the sound absorption plate is high in structural strength and excellent in flame-retardant performance and is low in smoke output in case of fire.

Description

technical field [0001] The invention relates to the field of sound-absorbing materials, in particular to a long-life sound-absorbing board. Background technique [0002] Sound-absorbing panel is a kind of sound-absorbing decorative material, which is mostly used in concert halls, theaters, recording rooms, conference rooms, KTV, bars, lecture halls and other places. Easy to cut, easy to assemble and other characteristics. However, the sound-absorbing panels in the prior art are mainly made of inferior chemical materials, which pollute the room to a greater degree, are not environmentally friendly, and the formaldehyde content is easy to exceed the standard. The machinable strength is low, the scrap rate is high, and the structural strength at the opening or incision is poor, which affects the local sound absorption performance of the sound-absorbing panel. Moreover, the existing sound-absorbing panels have potential safety hazards in terms of flame retardancy, and the amou...
