Abstract
The utility model relates to a sound -absorbing board, include plate body down be provided with an epoxy layer down on the plate body the top on epoxy layer is provided with the cotton layer of downdraught sound the top on the cotton layer of downdraught sound is provided with the porous ceramic grained layer, and the top of porous ceramic grained layer then is provided with the cotton layer of updraft type sound the top on the cotton layer of updraft type sound still is provided with the plate body. The utility model discloses choose for use the bilayer to inhale the sound cotton to be provided with the porous ceramic granule, when sound spreaded into the board surface into, some was reflected acoustic energy, in a part of hole that pierces through top layer entering porous ceramic granule and inhale cotton layer of sound, because the hole is mostly inside interpenetration's open pore, consequently can receive air molecular friction and viscous resistance, and make tiny fibre make mechanical oscillation, thereby make acoustic energy change heat energy into, and acoustic energy is by loss, strength retrogression, production absorbing effect.
Description
Technical field
The utility model relates to composite plate technical field, particularly relates to a kind of abatvoix.
Background technology
But, although the composite plate of prior art possesses certain sound absorption qualities, but for the installation environment such as place such as KTV, meeting room etc. that some sound-absorbing sound isolation requirements are high, the sound absorption qualities of prior art composite plate also cannot meet their demand, therefore develops new technology and to improve constantly the sound-absorbing soundproof effect of prior art composite plate be a thing the most necessary.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of abatvoix.
For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of abatvoix, including lower body, described lower body is provided with an epoxy resin layer, acoustical cotton layer under being provided above of described epoxy resin layer, being provided above porous ceramic particles layer at described lower acoustical cotton layer, be then provided with acoustical cotton layer above described porous ceramic particles layer, on described, acoustical cotton layer is arranged above upper plate body.
Improve further: the thickness of described epoxy resin layer is 0.8-1.3mm.
Improve further: the porous ceramic particles particle diameter in described porous ceramic particles layer is 0.2-0.3mm.
By using preceding solution, the beneficial effects of the utility model are: the particular design of the utility model each level order is to draw through repetition test, it it not simple superposition, this composite plate selects dual layer acoustical cotton, and it is provided with porous ceramic particles, when sound is passed to plate surface, an acoustic energy part is reflected, a part penetrates in the hole that top layer enters porous ceramic particles and acoustical cotton layer, owing to hole mostly is the open pore that internal mutual connects, therefore can be by air molecule friction and viscosity resistance, and make fiber fines make mechanical oscillation, so that acoustic energy is changed into heat energy, acoustic energy is depleted, strength retrogression, produce sound-absorbing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, the utility model is further illustrated.
nullWith reference to Fig. 1，The utility model embodiment disclose be，A kind of abatvoix，Including lower body 1，Described lower body 1 is provided with an epoxy resin layer 2，Epoxy resin layer 2 can not only improve good pliability，And may also function as certain sound-absorbing effect，The thickness of the most described epoxy resin layer 2 is 0.9mm，In actual production，As long as the thickness of this epoxy resin layer 2 all can implement the purpose of this utility model between 0.8-1.3，Acoustical cotton layer 3 under being provided above of described epoxy resin layer 2，It is provided above porous ceramic particles layer 4 at described lower acoustical cotton layer 3，Porous ceramic particles particle diameter in the most described porous ceramic particles layer 4 is 0.25mm，In actual production，As long as the particle diameter of this porous ceramic particles all can implement the purpose of this utility model between 0.2-0.3，Acoustical cotton layer 5 then it is provided with above described porous ceramic particles layer 4，On described, acoustical cotton layer 5 is arranged above upper plate body 6.
By using preceding solution, the beneficial effects of the utility model are: the particular design of the utility model each level order is to draw through repetition test, it it not simple superposition, this composite plate selects dual layer acoustical cotton, and it is provided with porous ceramic particles, when sound is passed to plate surface, an acoustic energy part is reflected, a part penetrates in the hole that top layer enters porous ceramic particles and acoustical cotton layer, owing to hole mostly is the open pore that internal mutual connects, therefore can be by air molecule friction and viscosity resistance, and make fiber fines make mechanical oscillation, so that acoustic energy is changed into heat energy, acoustic energy is depleted, strength retrogression, produce sound-absorbing effect.
Although specifically showing in conjunction with preferred embodiment and describing the utility model; implement this technical scheme method and approach is a lot; the above is only preferred embodiment of the present utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; the utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
Claims (3)
1. an abatvoix, including lower body, it is characterized in that: on described lower body, be provided with an epoxy resin layer, acoustical cotton layer under being provided above of described epoxy resin layer, it is provided above porous ceramic particles layer at described lower acoustical cotton layer, then being provided with acoustical cotton layer above described porous ceramic particles layer, on described, acoustical cotton layer is arranged above upper plate body.
