Abstract
The utility model relates to a composite sound absorption structure. The structure is characterized by comprising a perforation cover panel arranged on an inner layer, a material spraying layer arranged on an outer layer, and a flame-retardance and sound-absorption textile layer arranged between the perforation cover panel and the material spraying layer, wherein the flame-retardance and sound-absorption textile layer is bonded with the perforation cover panel through a bonding agent for dot coating; and the material spraying layer is sprayed on the surface of the flame-retardance and sound-absorption textile layer through special equipment. As the porous cover panel is arranged on the innermost layer, the flame-retardance and sound-absorption textile layer is arranged outside the porous cover panel, and the material spraying layer is sprayed on the surface of the flame-retardance and sound-absorption textile layer through equipment, a three-dimensional network structure without joints is formed, so that a defect of multiple joints in a traditional sound absorption structure of a perforation plate is radically overcome. The composite sound absorption structure can be widely applied in various indoor acoustic finishing.
Description
Technical field
The utility model relates to a kind of sound absorbent perforated structure that is applied to indoor noise reduction, particularly fits up employed compound sound-absorption structural about a kind of room acoustics.
Background technology
In the perforation of various thin plates and air layer is set behind plate, lining porous absorption material (glass fibre cotton etc.) in cavity in case of necessity, can form perforation board resonance sound absorption structure, because each perforate all has corresponding cavity behind, this perforated plate structure is the Helmholtz resonator of many parallel connections.General hardboard, veneer, gypsum plank, fiber cement board and steel plate, aluminium sheet, galvanized sheet all can be used as the raw material of perforated plate.The factor that affects perforated plate structure sound absorption characteristics mainly contains air layer thickness behind thickness of slab, aperture, perforated percentage and the plate.The purpose of sound absorption material is set mainly is to improve integrally-built sound absorbing capabilities to cavity behind the plate, expansion sound sucting band width.Generally speaking, when perforated percentage greater than 20% the time, the acoustic mass of perforated plate is very little, its acoustics effect reduces, this moment, the acoustic characteristic of whole sound absorption construction was mainly determined by the sound absorption material behind the plate, and perforated plate becomes the skin plate of sound absorption material.
At present, sound absorbent perforated structure is widely used in the room acoustics finishing, but along with the requirement to the outward appearance, acoustical behavior, material behavior (fire line, mildew resistance, crack resistance, uviolresistance etc.) etc. of finishing is more and more high, the inferior position of perforated plate constantly embodies.Such as, seam too obviously, outward appearance is too grave and stern, be difficult to dust in the cleaning hole, get both aesthetic appearance and fire line etc. of difficulty.
Summary of the invention
For the problems referred to above, the purpose of this utility model provides a kind of compound sound-absorption structural, its surfacing without seam, good looking appearance, easy to clean, processing is easy (can on-the-spotly lay), and sound absorbing capabilities long time stability, acoustic frequency bandwidth, the especially obvious compound sound-absorption structural of medium and low frequency acoustically effective.
For achieving the above object, the utility model is taked following technical scheme: a kind of compound sound-absorption structural, it is characterized in that: it comprises the punch cover panel that is arranged on internal layer, be arranged on outer field sprayed on material layer, be arranged on the fire-retardant acoustextile layer between described punch cover panel and the described sprayed on material layer; Described fire-retardant acoustextile layer is bonding by adhesive and the described punch cover panel of spot printing; Described sprayed on material layer is sprayed on described fire-retardant acoustextile layer surface by equipment.
The material of described punch cover panel is a kind of in steel plate, aluminium sheet and the galvanized sheet, and its thickness is 0.5～1.2mm.
The material of described fire-retardant acoustextile layer is glass fiber sound absorption cloth, and its thickness is 0.5～1mm.
The material of described fire-retardant acoustextile layer is a kind of decoration cloth cover in terylene, polypropylene fibre and the acrylic fibers by flame treatment, and its thickness is 0.5～1mm.
The sprayed on material of described sprayed on material layer is high gloss emulsion paint, satin emulsion, a kind of in silk emulsion, egg-shell gloss emulsion paint and the matt latex paint.
The sprayed on material of described sprayed on material layer is a kind of in fire-type emulsion paint, mould-proof-type emulsion paint, crack resistance type emulsion paint and the ultraviolet ray-resistance type emulsion paint.
The utility model is owing to take above technical scheme, have the following advantages: 1, the utility model is owing to fire-retardant acoustextile layer is set in the outside of traditional perforated plate, then spray a sprayed on material layer on the surface of fire-retardant acoustextile layer by equipment, therefore form a jointless dimensional network structure, fundamentally solved the many shortcomings of traditional sound absorbent perforated structure seam.2, the sprayed on material on the utility model acoustextile layer surface can be adjusted the color proportioning as required, and the spraying pattern enriches changeable.3, external surface of the present utility model is the sprayed on material layer, and spraying evenly flat appearance, has covered the seam of original fire-retardant acoustextile layer, has solved the shortcoming that traditional sound absorbent perforated structure hole is many, the slit is many, therefore cleans more easy.4, the utility model is based on the compound sound-absorption structural of traditional sound absorbent perforated structure, can carry out at the scene subsequent operation after the traditional sound absorbent perforated structure of laying is complete again, and it is more convenient to install.5, the utility model is to be that the punch cover panels outside of A level covers the acoustextile more than the fire-protection rating B1 level in fire-protection rating, and the two that has realized aesthetic appearance and fire line gets both.6, the utility model is owing to be according to the design of the acoustic construction of science, and material property is controlled, so the sound absorbing capabilities long time stability, acoustic frequency bandwidth, and especially the medium and low frequency acoustically effective is obvious.The utility model can be widely used in the various acoustic finishing environment, particularly outward appearance is had in the room acoustics finishing environment of specific (special) requirements.

The specific embodiment
The utility model comprises the punch cover panel 1 that is arranged on internal layer, is arranged on outer field sprayed on material layer 2, is arranged on the fire-retardant acoustextile layer 3 between punch cover panel 1 and the sprayed on material layer 2.
The parameters such as the pitch-row of the punch cover panel 1 that the utility model internal layer arranges, aperture, thickness of slab are basic identical with the parameter request of prior art middle punch plate, can adjust accordingly according to the actual acoustic requirement.Punch cover panel 1 can adopt the A level fire proofing materials such as steel plate, aluminium sheet, galvanized sheet, and the thickness of punch cover panel 1 is in 0.5～1.2mm scope.
The fire-retardant acoustextile layer 3 of the utility model should be selected the glass fiber sound absorption cloth of thickness between 0.5～1mm or the decoration cloth cover of the materials such as the terylene by flame treatment, polypropylene fibre, acrylic fibers.The decoration cloth cover of the materials such as glass fiber sound absorption cloth or the terylene by flame treatment, polypropylene fibre, acrylic fibers, its fire-protection rating should be more than the B1 level.Fire-retardant acoustextile layer 3 can be bonding by adhesive and the punch cover panel 1 of spot printing, avoids adhesive to affect integrally-built porosity.
