Definitions
- the present invention relates to a coated mineral wool product such as an an acoustically transparent ceiling panel or a facade insulation board in accordance with the preamble of claim 1 , a process for producing such a mineral wool product in accordance with claim 8, and a coating mass for producing an acoustically transparent mineral wool product in accordance with claim 1 3.
- sound absorbing wall and ceiling constructions are employed essentially for two tasks.
- this is the reduction of the sound level in a room in order to counteract noise in workplaces and living spaces
- a sound absorber effective for both applications must possess a sufficiently high flow resistance for the obtention of high friction losses, and at the same time a porous structure to better allow penetration by sound waves.
- sound absorption for example sound absorbing panels of mineral wool were used in the prior art. Sound deadening (sound absorption) is basically understood to be the conversion of sound energy into heat.
- mineral wool being a porous and open- cell material is particularly well suited. Energy conversion fundamentally takes place as a result of friction processes inside the absorber material.
- Open mineral wool products such as, e.g., mineral wool boards are not suited for acoustic insulation in interiors if only for esthetic reasons.
- the prior art consequently i.a. employed insulation boards of mineral wool provided on at least one side with a lining, or lamination, of resin-bonded glass fiber mat having a weight per surface unit between 20 and 1 50 g/m 2 .
- the glass fiber mats were provided with various decorative printings for esthetic reasons.
- the sound absorbing or acoustically transparent materials are moreover generally expected to be not flammable within the meaning of German Industrial Standard DIN 4102 Part 1 , building materials rating A.
- the glass fiber mats were applied onto the uncured mineral wool mat by means of a suitable adhesive and cured in a tunnel furnace. Following the curing process, mechanical molding into the corresponding size formats by means of machining units and finally packaging was carried out. Owing to this post-processing, however, a considerable amount of fiber material was discharged, which in turn results in soiling of the surface and associated cleaning work.
- a mineral wool product laminated with a fiber mat is coated on at least one side with a layer based on a siliceous material and containing at least one organic plastic, it was surprisingly found that the surface of the mineral wool product assumes a membrane-type character, i.e., it yields to pressure and springily resumes its former shape upon release of pressure, whereby the impact penetration strength is increased considerably.
- the surface of the mineral wool product according to the invention becomes markedly more resistant against any possible, inadvertent destruction occurring on the construction site.
- the layer may receive an admixture of paint pigments according to need, whence they fit in with the respective circumstances of interior design.
- the mineral wool products according to the invention present high degrees of sound absorption in comparison with conventional coated mineral wool products.
- the process according to the invention furnishes products having a faultless, clean surface, namely owing to the fact that the coating mass is applied only after the so-called tunnel furnace, i.e., when the mineral wool body is already present in the cured state.
- the coating mass is applied on the glass fiber mat in the form of a foam, for thereby it is possible to massage, as it were, the coating mass into the fiber mat and the adjacent body surface.
- This may, for example, be effected by means of an elastic roller, whereby an intimate connection between the surfaces of the fiber mat and of the underlying mineral wool is achieved through capillary effect.
- the coating may, however, also be carried out by immersion, spraying, flooding or doctor blade.
- the surface will, however, still be sealed in the wet state.
- the compound will obtain the actual open-pore, acoustically transparent surface only through the subsequent drying of the body surface coated with foam mass in a drying furnace, e.g., under intense infrared heating. Owing to this drying, the macroscopic air bubbles burst prior to curing of the coating mass and thus release the pores of the mat.
- both the mat fiber and the mineral fiber are enveloped by the coating mass which thus cures on the fiber.
- the compound of glass fiber mat with mineral wool thus allows for optimum spatial distribution of forces in the event of impact stress, which is furthermore assisted by an elastifying constituent in the mass.
- a coating mass having the following composition is used:
- EP 0 728 1 24 B1 stresses the importance of bitumen being prevented from penetrating through the coating material into the roof insulation boards thereof, or where used as so-called plaster base panels, their acquiring an affinity for the plaster mass.
- EP 0 728 1 24 B1 The coating mass of EP 0 728 1 24 B1 is deeply impressed into the mineral wool surface, bringing about cobweb-type bridges of coating material between the fibers.
- the inventive coating mass is applied on a fiber mat-laminated mineral wool product, generally a mineral wool board, resulting in the surprising properties of the mineral wool product according to the invention.
- a preferred coating mass is represented in claim 2, wherein the content of organic substances is irrelevant under the aspect of flammability.
- a mineral wool product in accordance with claim 4 has the advantage that - if the layer/coating is made to be electrically and/or magnetically effective, the mineral wool product may, e.g., be used as a radar absorber - or quite generally in the event of so-called electrosmog.
- Preferred substances for a coating for the purpose of radar radiation absorption are represented in claim 5.
- mineral wool products may be provided with a layer presenting, in accordance with claim 6, foam layer forming agents, particularly expanded graphite, pentaerythritol or the like which bring about thermally insulating properties in the case of a fire.
- foam layer forming agents particularly expanded graphite, pentaerythritol or the like which bring about thermally insulating properties in the case of a fire.
- the foamed coating mass is applied preferably in an application quantity of 100 g/m 2 to 500 g/m 2 , preferably approx. 300 g/m 2 in accordance with claim 9.
- a foam weight per liter of 100 g/l to 400 g/l, preferably approx. 250 g/l in accordance with claim 10 is used.
- the coating of the mineral wool product according to the invention is preferably dried in a drying kiln at a temperature of approx. 260 ° C.
- a drying kiln at a temperature of approx. 260 ° C.
- the macroscopic air bubbles within the layer burst prior to curing of the coating mass, resulting in the generation of an open-pore compound through which sound waves may penetrate into the inside of the mineral wool product to be absorbed there.
- the coating acquires a membrane-type character so as to have mechanical strength.
- Fig. 1 is a sectional view of a mineral wool product according to the invention.
- Fig. 2 is a graph showing impact penetration strength in accordance with the depth of impression.
- the board-shaped mineral wool product shown under 1 in the sectional view of Fig. 1 , presents a coating 2 of a suitable glass fiber mat 3 intimately combined with the surface of a body 4 of mineral wool.
- the glass fiber mat is adhered to the body 4 in the course of curing inside the tunnel furnace, namely as a result of the organic binder which gives shape to the body.
- the glass mat 3 adhered to the mineral wool body 4 has a weight per surface unit of approx. 60 g/m 2 .
- plastic dispersion a polyester-polyurethane dispersion by Bayer AG, water content: 50% having the tradename "Bayceram is used in the present embodiment. It is, of course, possible to use any plastic dispersion which is water and light resistant on the one hand and brings about particularly good elasticity on the other hand. Thus it is, for example, also possible to use latex dispersions.
- foaming agent W53 by Zschimmer & Schwarz was used in the exemplary case, and as a foam stabiliser PS1 , also by Zschimmer & Schwarz.
- the coating mass is foamed to about 6 times the unfoamed volume with the aid of an agitator.
- the foam weight per liter is approx. 250 g/l.
- the foamed coating mass is applied on the surface of the fiber mat 3 by means of an elastic roller. Through massaging the foam into the mat surface which is achieved with the aid of the elastic roller, and the capillary effect of the saulying mineral wool, an intimate permeation is achieved, with the surface still being sealed.
- the coated raw product is in the exemplary case dried in a drying kiln at intense infrared heating at approx. 260 ° C. Through this drying process, the macroscopic air bubbles burst prior to curing of the coating mass and form open pores 5 in the coating 2, which at least partly communicated with pores 6 of the glass fiber mat 3 and thus with the mineral wool body 4.
- Ceiling insulation boards 1 produced in this way present a membrane-type behavior on the side having the coating applied due to the springy-elastic properties of the compound of coating 2, glass mat 3 and mineral wool body 4.
- the ceiling panels 1 thus produced moreover present a high degree of sound absorption and present an appealing surface at markedly enhanced impact penetration strength in comparison with the conventional mineral wool products lined with fiber mats.
- Fig. 2 which shows the impact penetration strength plotted against the depth of impression, it can be seen that the impact penetration strength of the mineral wool products according to the invention is approximately tripled in comparison with glass fiber mats without a foam coating.
- the mineral wool products according to the invention 1 are thus on the one hand excellently suited for insertion in ceiling constructions of hung ceilings. On the other hand, however, owing to their high impact penetration strength, they are also well suited for use as facade insulation boards to allow for a reduction of the bulk densities thereof.
