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 application proposes an embodiment of a sound-absorbing panel for decorative building materials, which at least includes a combination of polyester fiber, polyamide resin, polyurethane resin and glass wool. Among them, polyamide resin and polyurethane 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 panel; glass wool can further improve the sound-absorbing performance of the sound-absorbing panel, and at the same time contribute to the lightweight of the panel Moreover, glass wool 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 w...

Abstract

The invention discloses an acoustic board for decorative building materials. The acoustic board at least comprises polyester fibers, polyamide resin, polyurethane resin and polyurethane. According to the scheme, the sound absorption performance of the acoustic board is adjusted and improved by improving material components of the acoustic board; the adopted materials are environmentally friendly, free of pollution and harmless to a human body, and the acoustic board is high in structural strength, excellent in flame retardant property and small in smoke discharge quantity when encountering a fire.

Description

technical field [0001] The invention relates to the field of sound-absorbing materials, in particular to a sound-absorbing board used for decorative building materials. 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 f...
