- the characteristics of the preamble of the process claim 1 or the device claim 5, is the one described above Acoustic panel known, in which one consists of a porous, elastic synthetic resin existing carrier plate with regard their sound absorption level is improved when they (on one or both sides) with thin cover layers from one Fleece or fabric covered with glass, synthetic or natural fibers is, the shape stability in a known manner the entire acoustic ceiling can be improved.
- the top layer (s) with the carrier plate is the Use of an adhesive provided, so applied should be that the porosity of the support plate and the top layers are not disturbed and the room air can circulate the acoustic panel.
- the top layer a layer composite the actual top layer and a plasterboard use so that the controversial conditions can be met are.
- the cover layer is by means of a binder attached to a base fabric; the same binder serves to glue the carrier fabric to the plasterboard, which is used in perforated execution to the desired sound permeability to the actual, to achieve sound-absorbing carrier plate.
- a backing fabric for the top layer is unfavorable, because its structure is on the room side, visible surface of the cover layer especially if the acoustic panel is connected by means of a Printing plate is compressed, which is already due to the adhesive layer is required.
- the carrier plate consists of a granulated with a binder, then secures otherwise such a compression also binds the individual grains.
- the application of such a grit is already described in the patent DE 14 84 072 C3 where the binder envelops both the individual grains as well as the cohesion of the grains.
- non-combustible acoustic panels of swollen pearlite or vermiculite as a grain for the carrier plate has been known for a long time, as well like the connection of the grain by means of an inorganic Binder. These acoustic panels also show the same Disadvantages, as already described in detail above have been.
- the invention has therefore set itself the task Process for producing an acoustic panel of the beginning specify the specified type and an acoustic panel, where the stated shortcomings of the prior art avoided become and a statically relatively highly resilient Acoustic panel both good sound absorbing and non-flammable is trained.
- the making of such Acoustic panel should be possible easily and inexpensively his.
- the adhesive is supposed to increase the porosity of the acoustic panel not significantly affect.
- the task is first performed by a method solved with the features of claim 1.
- the intermediate layer and the outer layer are together and with the carrier plate by means of an adhesive grid applied adhesive connected, initially the outer layer and the intermediate layer on top of each other an underlay serving as an abutment can be placed, whereby furthermore the adhesive grid in the manner on top facing layer surface of the intermediate layer applied is that the halftone dots from the adhesive make up the intermediate layer penetrate and contact the outer layer, after which the grain of the carrier plate as Filling applied to the top layer prepared in this way and that finally the acoustic panel by means of a the carrier plate loading pressure plate is compressed.
- the surface pressure on the top layer their application to the carrier plate is dependent on the thickness and consistency of the applied adhesive chosen that under the action of the pressure plate a sufficient fixed connection to the carrier plate without that the degree of coverage of the adhesive increases significantly becomes.
- the function of the acoustic panel remains in this way obtained, and at the same time the fibers of the Fleece or the fabric of the top layer (s) evenly glued together.
- the adhesive grid can be more or less wide-meshed trained and with little effort each Be adapted to the circumstances.
- the grain is advantageously formed by grains of are coated with a binder that is used in compression the pressure plate binds the individual grains together, so that a stable carrier plate with high porosity is created.
- the stiffness of the acoustic panel is increased when the surface of the carrier plate facing away from the room with a another top layer is provided on the bed the support plate before compression of the acoustic plate is launched.
- This top layer can be made up of one piece Glass fiber fleece or the like exist.
- a perfect, highly resilient connection of the different The acoustic panel is stratified if the bonded acoustic panel after compression by the Pressure plate is cured, preferably at a temperature between 140 and 250 ° C.
- the acoustic panel can be on its panel surface facing away from the room the carrier plate with another, preferably undivided cover layer, for example from a relative coarse-pored and dimensionally stable fleece or fabric his.
- the carrier plate advantageously consists of a granular Material that is cohesive, for example by means of a binder, interconnected grains becomes.
- the grains preferably made of a mineral material such as expanded glass, expanded clay, basalt balls, pearlite or the like or a mixture formed by these, can have a grain size between 0.25 and 8 mm and, like the binder, from an inorganic Material.
- a mineral material such as expanded glass, expanded clay, basalt balls, pearlite or the like or a mixture formed by these
- the binder can have a grain size between 0.25 and 8 mm and, like the binder, from an inorganic Material.
- There is water glass for the binder proven, preferably enriched with one or more Additives such as phosphates or the like.
- the intermediate layer and / or the outer layer is a inorganic fleece or fabric preferably made of glass fibers suitable
- the intermediate layer is best of a Glass fiber mat
- the outer layer of a glass fiber fleece is formed.
- the adhesive can form a point-by-point adhesive grid, the halftone dots formed by adhesive particles each of which is the backing plate, the intermediate layer and connects the outer layer together. It but it is also possible that the adhesive, in each case between the carrier plate and the cover layers and / or between the intermediate layer and the outer layer, as a lattice-shaped Adhesive grid is formed, for example in Form of an adhesive fleece. It preferably consists of a mixture of water glass and aggregates, in particular Phosphates.
- An acoustic panel according to the invention is highly noise and also can be used in a heat-insulating manner and, in spite of this, has extraordinary low weight, high dimensional stability, without the covering layer (s) being applied over a large area Adhesive film attached to the carrier plate is (are).
- the acoustic panel is sufficient for an inventive one Production of all fire protection requirements and can be manufactured economically.
- an acoustic panel according to the invention A can be seen which consists of a carrier plate T and there is a cover layer D, (Fig.1) the cover layer D fixed on a plate surface F facing a space R. shall be.
- the cover layer D lies on one in the Drawing omitted stationary, flat base, which continue to act as an abutment when compressing the acoustic panel A serves.
- the carrier plate T is made up of a bulk TS of individual Grains TK by pressing using a pressure plate P manufactured.
- Fig.1 are the loose fill TS of the grains TK and in Fig.2 the sintered from it Grain TK 'of the carrier plate T symbolically indicated.
- the Grains TK are from the start with a binder coated, which after pressing the bulk TS Cohesion of the grain TK 'causes.
- the cover layer D consists of a plate surface F. contacting intermediate layer DZ and a room R facing Outer layer DA, both of which are designed to cover the entire surface are.
- the intermediate layer DZ is made of a relative coarse-pored and rigid, the outer layer DA, however made from a fine-pored, flexible fleece.
- the outer layer DA and the intermediate layer are shown in FIG Double room laid on top of each other and dot-matrix with one Adhesive K covered, which concentrates in the halftone dots is; its quantity and consistency as well as the porosity the intermediate layer DZ are dimensioned so that the Adhesive particles K 'in the halftone dots alone their gravity and by the loading from the bed TS penetrate the intermediate layer DZ and the outer layer Contact DA or flow into their surface to a limited extent.
