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 an embodiment of a sound-absorbing panel for architectural decoration, which at least includes a combination of polyester fiber, epoxy resin, polyurethane resin and fir wood chips. Among them, epoxy resin and polyurethane resin are used to improve the structural strength and toughness of polyester fibers, and at the same time help to increase the sound absorption coefficient of sound-absorbing panels; , fir wood can ensure that the board can still have excellent sound absorption performance even in a humid environment.

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

Abstract

The invention discloses a sound-absorbing board for architectural decoration, which at least comprises a combination of polyester fiber, epoxy resin, polyurethane resin and Chinese fir sawdust. In this case, the adjustment and improvement of the sound-absorbing performance of the sound-absorbing board is realized by improving the material components of the sound-absorbing board; the materials used in this case are environmentally friendly and pollution-free, harmless to the human body, and the sound-absorbing board itself has high structural strength and excellent flame retardancy. Low smoke output in case of fire.

Description

technical field [0001] The invention relates to the field of sound-absorbing materials, in particular to a sound-absorbing board for architectural decoration. 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 retar...
