Abstract
The utility model discloses a composite damping noise barrier; a substrate layer of the composite damping noise barrier is covered with a damping layer; and a surface layer is covered on the damping layer. By adopting a sound insulation structure, the composite damping noise barrier is safe and convenient to use, good in comprehensive sound insulation effect, simple in technology and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of sound insulating panel, specifically a kind of composite damping sound insulating panel.Belong to building material field.
Background technology
The harm of noise pollution is serious day by day, and the effective method of administering noise pollution carries out sound insulation, sound-absorbing and damping exactly to be handled, and material commonly used is exactly various sound insulating sheet materials.But existing sound insulating panel all is the effect of playing sound insulation, and noise control effect is limited, and other poor-performing of sheet material, like fireproof performance, timber intensity or the like.
The utility model content
The utility model technical problem to be solved overcomes the deficiency of above-mentioned prior art exactly, provides a kind of sound-absorbing effect good, and has the composite damping sound insulating panel of fire-proof function.
The utility model adopts following technical scheme:
A kind of composite damping sound insulating panel covers damping layer on basalis, covering surfaces layer on damping layer.
Further, described damping layer thickness is 0.5mm-3mm.
Further, the surface layer thickness of stating is 3mm-10mm.
Further, described surface course is a foamed aluminium board.
Further, described basalis is a gypsum plank.
Further, described basalis is a cement board.
Further, described basalis is a steel plate.
Further, described damping layer is a water-based sound-proof glue.
The beneficial effect of the utility model is:
(1) sound-absorbing effect is good.The foamed aluminium board of surface course all has good sound-absorbing effect for the noise of each frequency, and particularly for the medium and low frequency noise, acoustically effective obviously is superior to sound insulating panel in the past.Its sound absorption coefficient when mid-frequency of octave band 125Hz is higher than 0.85; When 500Hz, be higher than 0.78, when 2000Hz, be higher than 0.7.The good sound absorption effect is all arranged in from the low frequency to the high-frequency range.(2) comprehensive soundproof effect is good.The foamed aluminium board of surface course carried out the sound-absorbing processing to noise when, foamed aluminium board and damping layer, basalis had constituted constrained damping structure again, have the favorable damping noise reduction.The sound insulation factor that integrates this kind sound insulating panel is safe and convenient to use up to 30-60 decibel (3).The sound insulating structure that the utility model adopts, its basalis is ordinary gypsum board or cement board or steel plate, and surface course is a foamed aluminium board, and fireproof performance is excellent.Only need to apply adhesive during use and paste that to get final product (4) technology simple, cheap at the basalis back side.The material price of making the required employing of the utility model is cheap, and manufacturing process is also very simple.(5) use extensively.Because the utility model is simple in structure, cheap, easy to use, sound-absorbing effect is good to the environment for use requirement is low, thus not only can be as the deadener of equipment, and it is strong also can be used in other occasion (6) designabilities that much need administer noise.Can carry out concrete design according to different instructions for uses, like material, the thickness of adjustment basalis, the thickness of surface course foamed aluminium board and porosity, thickness of damping layer or the like.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model embodiment.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model discloses a kind of composite damping sound insulating panel, this sound insulating panel covers damping layer 2, covering surfaces layer 3 on damping layer 2 on basalis 1.In use, can be directly paste sound insulating panel disclosed in the utility model and be arranged in around the sound source with adhesive or adhesive sticker, very convenient.
Embodiment 1, and in the present embodiment, basalis 1 is selected steel plate for use; Its thickness can be selected according to actual conditions flexibly, and the damping layer 2 that covers on the basalis is water-based sound-proof glue, and its thickness is 0.5mm; The surface course 3 that covers on the damping layer 2 is foamed aluminium board, and its thickness is 3mm.
Embodiment 2, and the difference of a present embodiment and a last embodiment is that basalis 1 selects cement board for use, and the thickness of damping layer 2 is 2mm, and the thickness of surface course 3 is 6mm.
The above; It only is preferred embodiment to the utility model; Be not to be that the utility model is done other forms of restriction, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.Every content that does not break away from the utility model technical scheme to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the scope that the utility model technical scheme is protected according to the technical spirit of the utility model.
