Abstract
The utility model discloses a gypsum acoustic board which comprises a gypsum board and coatings, wherein the gypsum board is provided with a plurality of through holes, and the coatings are respectively adhered to the upper surface and the lower surface of the gypsum board and cover the upper surface and the lower surface of the gypsum board. A noise reduction coefficient of the gypsum acoustic board can achieve NRC0.8 above of level A by attaching fiber acoustic absorption felts or other acoustic absorption coatings on two faces of the acoustic board, so that a better acoustic absorption effect can be achieved, and a high standard requirement for indoor acoustic absorption and noise reduction is met.
Description
Technical field
The utility model relates to a kind of acoustical board, particularly a kind of gypsum acoustical board.
Background technology
Acoustic enviroment is had relatively high expectations and the place of top grade decoration at some, such as places such as cinema, concert hall, library, museum and hospitals acoustical board is installed all, thereby is used for absorbing the generation that sound is avoided noise as far as possible.And present indoor acoustical board kind is a lot, and such as gypsum acoustical board, wooden acoustical board etc., and when adopting gypsum plank as base material, conventional way all is to take hole to run through to reach the effect of sound absorption gypsum plank at present.And in order to obtain better acoustically effective, can also behind the gypsum plank perforated holes, post one deck sound absorption fibrofelt by single face, thereby reach the purpose of the indoor sound absorption reduction of gypsum acoustical board, but the noise reduction coefficient of present gypsum acoustical board substantially all is lower than A level NRC(noise reduction coefficient) 0.8, therefore can not reach the sound absorption reduction requirement of higher standard, much require very high place just no longer applicable to fire protection flame retarding.
The utility model content
The technical problems to be solved in the utility model be for overcome in the prior art gypsum acoustical board take hole to run through or perforated holes after post one deck fiber baffle blanket at single face and cause noise reduction coefficient to be lower than the defective of A level NRC0.8, a kind of gypsum acoustical board is provided.
The utility model solves above-mentioned technical problem by following technical proposals:
The utility model provides a kind of gypsum acoustical board, and its characteristics are that it comprises a coating that has the gypsum plank of a plurality of perforated holes and be adhered to respectively and cover the upper and lower surface of described gypsum plank.
Existing gypsum acoustical board substantially all is to take hole to run through, perhaps at the most behind perforated holes single face post the purpose that one deck fiber baffle blanket reaches sound absorption reduction, this has become the acquiescence design of gypsum acoustical board for a long time, and the noise reduction coefficient of the gypsum acoustical board that obtains in this way substantially all is lower than A level NRC0.8, therefore sound absorption reduction effect and bad does not reach high-level sound absorption requirement.
And the utility model is changed the design of traditional gypsum acoustical board, at equal bonding one coating that can all cover described upper and lower surface of the upper and lower surface of gypsum acoustical board.Like this, through the two-sided gypsum acoustical board that posts fiber baffle blanket or other sound absorption coating, in its hole, just formed a hole cavity that more meets the principle that absorbs sound, so that the index coefficient of its sound absorption reduction reaches more than the A level NRC0.8, thereby so that gypsum acoustical board of the present utility model more meets the high-level requirement of indoor sound absorption reduction.
Preferably, described coating is glass mat or nonwoven, and described coating itself has acoustically effective, so just can further optimize the acoustically effective of described sound absorption PLASTIC LAMINATED, and certainly, described coating also can have for other felt, cloth of acoustically effective.
Preferably, described perforated holes is circular opening, oval hole or polygon hole.Wherein, described polygon hole specifically comprises triangle hole, square hole, pentagon hole etc.
Preferably, also be provided with the hole of a plurality of chadlesses on the described gypsum plank.
Positive progressive effect of the present utility model is: the utility model is by two-sided fiber baffle blanket or other sound absorption coating of all posting at the gypsum acoustical board, so that noise reduction coefficient of the present utility model can reach more than the A level NRC0.8, thereby can obtain better acoustically effective, and more meet the high-level requirement of indoor sound absorption reduction.

The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Embodiment 1
Shown in Fig. 1-4, the gypsum acoustical board of present embodiment comprises a gypsum plank 1, have a plurality of perforated holes 2 on the described gypsum plank 1, and the upper and lower surface of described gypsum plank 1 all is bonded with the coating 3 that can cover described upper and lower surface.
The utility model is changed the design of traditional gypsum acoustical board, by at the equal bonding described coating 3 of the upper and lower surface of gypsum acoustical board, and in its perforated holes 2, just formed a hole cavity that more meets the principle that absorbs sound through the two-sided gypsum acoustical board that posts coating, so that the index coefficient of the sound absorption reduction of described gypsum acoustical board reaches more than the A level NRC0.8, thereby so that the gypsum acoustical board of present embodiment has better acoustically effective, and more meet the high-level requirement of indoor sound absorption reduction.
Specifically referring to Fig. 1 and Fig. 2, the gypsum plank 1 of present embodiment is perforating gypsum board, described a plurality of perforated holes 2 is all through monoblock gypsum plank 1, described a plurality of perforated holes 2 is circular opening, certainly in specific implementation process, also can be other shape, such as polygon hole or oval holes such as triangle hole, square holes.These set-up modes, all be well known in the art can be so that gypsum plank has the set-up mode of acoustically effective, its principle that specifically absorbs sound just repeats no more at this.
And described coating 3 can be glass mat or nonwoven, and described coating 3 itself has acoustically effective, so just can further optimize the acoustically effective of described sound absorption PLASTIC LAMINATED, and certainly, described coating 3 also can have for other felt, cloth of acoustically effective.
Certainly, in specific implementation process, for so that gypsum acoustical board of the present utility model more attractive in appearance, have a better visual sense of beauty, can also carry out the PROCESS FOR TREATMENT of sound absorption coating at the upper surface of described gypsum plank 1, specifically as shown in Figure 3, can arrange at the upper surface of described gypsum plank 1 the crystal point-like, have the decorative coveringn of colour image.And in Fig. 4, then demonstrated at the bonding described coating 3 of the upper and lower surface of described gypsum plank 1.
Shown in Fig. 5-8, the difference of present embodiment and the first embodiment is: in the present embodiment, also be provided with the hole 4 of a plurality of chadlesses on the described gypsum plank, thereby so that the gypsum acoustical board of present embodiment has the better acoustically effective than the first embodiment.
Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
