Abstract
The utility model discloses a polyester fiber sound absorbing panel in a microporous structure. The panel comprises sound absorbing panel bodies and low-melting-point fiber layers pressed by multiple layers. The sound absorbing panel bodies are made from polyester fiber, and dense micropores are acupunctured in the top and bottom faces of the sound absorbing panel bodies. The low-melting-point fiber layers are arranged between two adjacent sound absorbing panel bodies. The sound absorbing panel bodies and low-melting-point fiber layers pressed by multiple layers are spliced together through high temperature hot melting and quick grinding. The polyester fiber sound absorbing panel in the microporous structure provided by the utility model comprises the sound absorbing panel bodies and the low-melting-point fiber layers pressed by multiple layers, so that the plate is thick, reasonable in structure, low in cost, low-carbon and environment-friendly and good in sound absorbing effect.
Description
Technical field
The utility model relates to acoustic board, is specifically related to a kind of polyester fiber acoustic board of microcellular structure.
Background technology
Adopt mineral wool, gypsum and wooden perforated plate as acoustic board traditionally, the cost height of these materials, not environmental protection, unreasonable structure, thickness is little, and acoustically effective is poor.
The utility model content
Technical problem to be solved in the utility model is acoustic board cost height, not environmental protection, and unreasonable structure, thickness is little, the problem of acoustically effective difference.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts provides a kind of polyester fiber acoustic board of microcellular structure, comprise acoustic board body and low-melting fiber layer that multilayer presses together, described acoustic board body material is polyester fiber, acupuncture has intensive micropore on its end face and the bottom surface, be the low-melting fiber layer between adjacent two described acoustic board bodies, the described acoustic board body of multilayer and low-melting fiber layer bond together by the high temperature hot melt with after rolling fast.
In the polyester fiber acoustic board of above-mentioned microcellular structure, the micropore up/down perforation on every layer of described acoustic board body.
In the polyester fiber acoustic board of above-mentioned microcellular structure, the thickness of acoustic board is 5-15mm.
The polyester fiber acoustic board of the microcellular structure that the utility model provides comprises acoustic board body and the low-melting fiber layer that multilayer presses together, and thickness is big, and is rational in infrastructure, and cost is low, low-carbon environment-friendly, and acoustically effective is good.
Description of drawings
The structural representation of the polyester fiber acoustic board of the microcellular structure that Fig. 1 provides for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the polyester fiber acoustic board of the microcellular structure that the utility model provides comprises acoustic board body 1 and the low-melting fiber layer 2 that multilayer presses together, acoustic board body 1 material is polyester fiber, and acupuncture has intensive micropore 11 on its end face and the bottom surface, forms the high density microcellular structure.Be low-melting fiber layer 2 between adjacent two acoustic board bodies 1, multilayer acoustic board body 1 and low-melting fiber layer 2 bond together by the high temperature hot melt with after rolling fast, low-melting fiber layer 2 is in fusing or the state of semi-molten under the high temperature, plays the effect that is adhesively fixed after rolling cooling.
In the present embodiment, micropore 11 up/down perforations on every layer of acoustic board body 1, the micropore 11 between adjacent two acoustic board bodies 1 is interlaced arrangement, acoustically effective is better like this.
The integral thickness of the acoustic board that the utility model provides is 5-15mm, adopts reciprocating type shop cotton machine device to carry out reciprocating type shop cotton between layer and the layer and rolls increase thickness fast.
The polyester fiber acoustic board of the microcellular structure that the utility model provides adopts the Polyester Fibers that reclaims, saved cost, product itself also be can 100% recycling material, the product that belongs to low-carbon environment-friendly, surrounding enviroment there is not any pollution, and acoustic absorptivity is more superior than acoustic boards such as traditional mineral wool, gypsum, wooden perforated plates, and acoustic absorptivity is up to 0.9.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
Claims (3)
1. the polyester fiber acoustic board of microcellular structure, it is characterized in that, comprise acoustic board body and low-melting fiber layer that multilayer presses together, the material of described acoustic board body is polyester fiber, acupuncture has intensive micropore on its end face and the bottom surface, be the low-melting fiber layer between adjacent two described acoustic board bodies, the described acoustic board body of multilayer and low-melting fiber layer bond together by the high temperature hot melt with after rolling fast.
