At present, passive treatment is generally adopted for treating life and work noise, namely, an acoustic screen is arranged between a noise source and a receptor. The main sound absorption part of the sound absorption screen body is a sound absorption plate. The acoustic baffle divide into metal acoustic baffle and non-metal acoustic baffle according to the material, for pleasing to the eye and quality consideration, adopt metal acoustic baffle mostly, metal acoustic baffle adopts aluminum plate or steel sheet to bend into the box body on the existing market mostly, mineral wool such as inside packing glass fiber wool, low cost, but can be because the reason of its own composition in the manufacturing of acoustic material such as mineral wool and the use, cause secondary pollution to the environment, and its sound absorption principle is single (porous sound absorption) etc., along with the country constantly improves to the attention degree in the aspect of the environmental protection, the trend of being eliminated by market gradually has appeared to the acoustic baffle of this kind of material, consequently, need provide a new metal acoustic baffle.
SUMMERY OF THE UTILITY MODEL
For solving the problem that exists among the prior art, the utility model provides a novel combined type metal acoustic baffle.
The utility model adopts the technical proposal that:
the utility model provides a novel combined type metal acoustic baffle, includes micropore metal decking, micropore metal decking opens the micropore that has certain porosity and a determining hole interval, one side of micropore metal decking bonds the metal fiber sound absorption cloth that has certain unit weight and thickness, the opposite side of metal fiber sound absorption cloth bonds the certain thickness of one deck and has certain cavity volumetric aluminium honeycomb panel, the metal fiber sound absorption cotton of the certain thickness of one deck and unit weight is arranged to aluminium honeycomb panel opposite side, be provided with the resonance cavity of certain degree of depth between metal fiber sound absorption cotton and the metal backplate.
Preferably, a plurality of micropores with the pore diameter smaller than 1mm are uniformly distributed on the surface of the micropore metal panel.
Preferably, a layer of metal fiber sound absorption cloth is bonded between the microporous metal panel and the aluminum honeycomb panel.
Preferably, the micropore metal panel, the metal fiber sound absorption cloth, the aluminum honeycomb panel, the metal fiber sound absorption cotton and the metal back plate are all made of metal aluminum.
Preferably, the hole metal panel, the metal fiber sound absorption cloth and the aluminum honeycomb panel are bonded by TPU hot melt adhesive, and the TPU hot melt adhesive is heated and melted to realize bonding to form the TPU hot melt adhesive film.
Preferably, a resonant cavity with a certain depth is arranged between the metal fiber sound absorption cotton and the metal back plate.
The utility model has the advantages that:
the sound absorption plate has the functions of porous sound absorption and resonant sound absorption by arranging the microporous metal panel, the metal fiber sound absorption cloth, the aluminum honeycomb plate, the metal fiber sound absorption cotton and the resonant cavity, and the sound absorption performance of the sound absorption plate is improved; meanwhile, the aluminum honeycomb panel is adopted to replace a supporting structure in the existing sound absorption panel, so that the overall strength of the sound absorption panel is ensured, the overall weight of the sound absorption panel is greatly reduced, and the transportation cost is effectively reduced; all parts of the sound absorption plate are made of metal aluminum, so that the whole weather resistance is excellent, the coloring effect is good, and the whole attractiveness is high.
To sum up, the utility model provides an acoustic baffle, whole light in weight, the bulk strength is high, and the cost of transportation is low, and weatherability is excellent, and the appearance can be painted the processing, and pleasing to the eye degree is high.
