Description

Technical Field

[0001] The utility model relates to the technical field of gypsum boards, in particular to a fireproof and soundproof gypsum board. Background Art

[0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, good sound insulation, heat insulation and fire resistance, and is one of the new lightweight boards currently being developed.

[0003] However, gypsum board can only perform simple sound insulation when used for sound insulation. It has poor sound insulation effect for high-decibel noise and cannot completely eliminate noise, resulting in poor sound insulation and noise reduction effects.

[0004] Therefore, we propose a fireproof and soundproof gypsum board to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a fireproof and soundproof gypsum board to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a fireproof and soundproof gypsum board, comprising a gypsum core, a mineral wool sound-absorbing board is pasted on the surface of the gypsum core, a sound-absorbing layer is pasted on the surface of the mineral wool sound-absorbing board, and a plurality of groups of sound-absorbing tubes are fixedly connected inside the gypsum core;

[0007] A plurality of groups of sound-absorbing tubes are evenly distributed in the gypsum core, the sound-absorbing tubes are bent, and the inner walls of the sound-absorbing tubes are fixedly connected with sound-absorbing sheets.

[0008] Preferably, a protective coating is sprayed on the surface of the sound absorbing layer.

[0009] Preferably, the sound absorbing sheet is made of rock wool.

[0010] Preferably, the thickness of the gypsum core is 1.8 mm, and the overall thickness is 50 mm.

[0011] Preferably, the sound absorbing layer is made of poplar wood fiber.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The sound-absorbing tube forms multiple holes on the surface of the gypsum core. The sound waves penetrate into the interior along the sound-absorbing tube and come into contact with the sound-absorbing tube and the sound-absorbing sheet inside the sound-absorbing tube, converting the sound energy into heat energy, and reducing the sound energy to achieve noise reduction.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a fireproof and soundproof gypsum board, comprising a gypsum core 1, which is a mixture of gypsum, cellulose and filler. The gypsum and cellulose make the gypsum core 1 have certain sound insulation and fireproof capabilities. The mineral wool sound-absorbing board 2 pasted on the surface of the gypsum core 1 further enhances the overall sound absorption capacity. The sound-absorbing layer 3 pasted on the surface of the mineral wool sound-absorbing board 2 is a layer made of poplar wood fiber as the main material. The outer surface has a filamentous texture, which is rough and unique, has a good sound absorption effect, and further enhances the noise reduction effect.

[0020] For details, please refer to Figure 1-3 The sound-absorbing tube 4 forms a plurality of holes on the surface of the gypsum core 1. The sound waves penetrate into the interior of the gypsum core 1 along the sound-absorbing tube 4 and collide with the sound-absorbing tube 4 and the sound-absorbing sheet 5 inside the sound-absorbing tube 4, converting the sound energy into heat energy, thereby reducing the sound energy and achieving noise reduction.

[0021] Working principle: The gypsum core 1 is a mixture of gypsum, cellulose and filler. Gypsum and cellulose make the gypsum core 1 have certain sound insulation and fire resistance. The mineral wool sound-absorbing board 2 pasted on the surface of the gypsum core 1 further enhances the overall sound absorption ability. The sound-absorbing layer 3 pasted on the surface of the mineral wool sound-absorbing board 2 is a layer with poplar wood fiber as the main material. The outer surface has a filamentous texture, which is rough and unique, and has a good sound absorption effect, further enhancing the noise reduction effect. The sound-absorbing tube 4 forms a plurality of holes on the surface of the gypsum core 1. The sound waves go deep into the interior along the sound-absorbing tube 4 and touch the sound-absorbing tube 4 and the sound-absorbing sheet 5 inside the sound-absorbing tube 4, converting the sound energy into heat energy, converting and reducing the sound energy, and realizing noise reduction. This solves the problem that the gypsum board can only perform simple sound insulation when performing sound insulation, has poor sound insulation effect for high-decibel noise, and cannot complete sound elimination, resulting in poor sound insulation and noise reduction effects.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
