Abstract
The utility model relates to an insulating sound absorbing board with fire prevention, which is composed of a sound absorbing non-woven fabric and an insulating epoxy laminating board with fire prevention. A middle part is adhered by adhesive. The insulating epoxy laminating board with fire prevention is provided with holes distributed according to certain intervals. The thickness of the sound absorbing non-woven fabric is between 0.1 mm to 1 mm and the containing weight is between 30g/m#+[2] to 100g/m#+[2]. The back surface of the sound absorbing non-woven fabric is coated with fire preventing paint. The thickness of the insulating epoxy laminating board with fire prevention is between 0.1 mm to 2 mm and the insulating epoxy laminating board uses the punching rate of 15% to 25% and the hole diameter of 1 mm to 10 mm.
Description
Technical field
The utility model relates to sound absorber, particularly a kind of fire retardant insulating acoustical board.
Background technology
In the prior art, usually adopt the sound absorption construction that constitutes by gypsum plank with holes, glass wool, wood fiber slab or flannelette etc. to abate the noise, in addition, in the cinema, conference room, wall or ceiling that recording rooms etc. have the space of special acoustics requirement also often adopt by gypsum plank with holes, the sound absorption construction of formations such as glass wool, wood fiber slab or flannelette is come guide sound wave reflection and reverberation time, to keep sound clarity.But because gypsum plank, materials such as glass wool, wood fiber slab or flannelette have the effect of accumulation of heat, are unfavorable for temperature controlling, and its mechanical strength is low, no fire-retardant and the insulation function, in the place that plant equipment install to be concentrated, particularly during the electric control appliance occasion, security performance is not high, and the space that these materials occupy is big, in addition, the sound absorption coefficient of these materials can only reach about 0.5-0.6, and acoustically effective is not good.
Summary of the invention
The utility model is for solving existing acoustical board in deficiencies such as fire-retardant, insulation and sound absorption coefficient are low, a kind of fire retardant insulating acoustical board is provided, described fire retardant insulating acoustical board is made of acoustic absorption nonwoven fabrics and flame-proof insulating epoxy laminate, wherein, described acoustic absorption nonwoven fabrics and flame-proof insulating epoxy laminate adopt adhesive bonding, described acoustic absorption nonwoven fabrics thickness is between 0.1mm-1mm, and unit weight is at 30g/m
2-100g/m
2Between, described flame-proof insulating epoxy laminate thickness is between 0.1mm-2mm, and the perforated percentage of employing 15%-25%, and the aperture is 1mm-10mm, further, in order to reach technical performance preferably, the thickness of described flame-proof insulating epoxy laminate adopts 0.8mm, and adopts 18% perforated percentage, the aperture is 4mm, the described acoustic absorption nonwoven fabrics back side scribbles fireproof paint, and thickness adopts 0.2mm, and unit weight is 61g/m
2
The utility model compared with prior art, the sound absorption coefficient height, fire-retardant, the insulation, the dust suction amount is few, and it is little to occupy the space.The utility model fire retardant insulating acoustical board is as shown in the table at the sound absorption coefficient of six octave center frequencies of 125HZ-4KHZ:
| Octave center frequency (HZ) | ||||
| 250 | 500 | 1000 | 2000 | |
| Sound absorption coefficient | 0.95 | 1.08 | 0.86 | 0.78 |
As can be known from the above table, the utility model fire retardant insulating acoustical board sound absorption coefficient is all greater than 0.7.Bending strength 〉=the 300Mpa of the flame-proof insulating epoxy laminate that the utility model fire retardant insulating acoustical board is adopted, impact strength 〉=98KJ/m
2, vertical proof voltage 〉=14.8KV/m, surface insulation resistance 5 * 105M Ω, fireproof performance is the B1 level.
Description of drawings
Fig. 1 is the schematic diagram of a kind of fire retardant insulating acoustical board of the utility model.
The specific embodiment
As shown in Figure 1, a kind of fire retardant insulating acoustical board of the utility model is made of acoustic absorption nonwoven fabrics 1 and flame-proof insulating epoxy laminate 3, and the middle adhesive 2 that adopts is bonding, the layer of adhesive 2 that is provided with between described acoustic absorption nonwoven fabrics 1 and the flame-proof insulating epoxy laminate 3 can help to adhere to.In a preferred embodiment of the present utility model, acoustic absorption nonwoven fabrics 1 thickness adopts 0.2mm, and unit weight adopts 61g/m
2, acoustic absorption nonwoven fabrics 1 back side scribbles fireproof paint, and the thickness of flame-proof insulating epoxy laminate adopts 0.8mm, and to adopt 18% perforated percentage, aperture be 4mm, and the hole on the flame-proof insulating epoxy laminate 3 is equilateral triangle and arranges.
