Definitions

  • the invention relates to a method for producing mineral fiber boards that can be used as a plaster base, in particular facade insulation boards, in which method the mineral fibers provided with a binder are accumulated to form a mineral fiber layer, the mineral fiber layer is split into at least two partial webs, at least one of the partial webs is compressed, the compressed partial web is fed to the or the other partial webs and the partial webs are combined by curing the binder to form a web which has at least one layer of high density and one layer of low density.
  • a method is described in Canadian Patent 1,057,183. In the plates produced in this way, the fibers lie in parallel planes. They are therefore unsuitable or only poorly as facade panels, because there is a risk of delamination with this use. This danger is particularly great if suction forces act on the facade due to strong winds.
  • the Swiss patent specification 620 861 describes a method in which mineral fibers wetted with a binder are deposited on a conveyor device running at a first conveying speed in order to form a mineral fiber layer in order to feed them to a continuous furnace, the conveying device of which is equipped with a second , reduced speed runs.
  • the mineral fiber layer is at Entry into the continuous furnace is alternately bulged and then compressed in its thickness so that it has a practically flat surface after hardening.
  • the plates produced in this way have a compressive strength and tensile strength at right angles to the plane of the plate, which is considerably higher than that of plates in which the fibers run in parallel planes.
  • the plate described can be manufactured with a smaller density and thus cheaper than a plate with parallel fibers.
  • the arrangement of the fibers in the plate described has a relatively high regularity. This makes it possible to use fewer binders in the production of the plates than in the previous processes.
  • the panels produced in this way are not suitable as facade insulation panels for the production of a plastered facade because plaster adheres insufficiently due to the hydrophobic nature of the panel material.
  • the insulation board according to DE-C-24 55 691 provides a coating of water glass with additions of fine-grained clay mineral substances. However, this requires thermal post-curing at relatively high temperatures. However, high temperatures have an unfavorable effect on the binder of the fibers and thus on the mechanical strength of the mineral fiber board.
  • EP-B-0 114 965 proposes to provide facade or roof insulation boards made of synthetic resin-bound mineral fibers with a coating based on colloidal silica and particulate organic additives .
  • This coating consists of an impregnation layer and a surface layer.
  • the impregnation layer is created by pressing the coating composition into the resin-bonded mineral fiber board, breaking fibers in the area near the surface, and has a thickness of one or more millimeters.
  • the top layer above the impregnation layer surface layer is formed from the coating material itself. It has the shape of a closed film and completely covers the broken surface fibers, so that they do not appear anywhere on the surface.
  • Ground basalt fibers, kaolin and / or aluminum hydroxide are mentioned as inorganic additives in a quantity which is practically the same size or larger than the solids content of the colloidal silica.
  • the addition of ground basalt fibers is considered necessary in order to fill the gaps between the broken mineral fibers of the insulation board with fiber structures and to enable a closed top layer.
  • the plate described has a number of disadvantages. Because of the necessary, relatively high density, a lot of fiber material is required to manufacture the plate.
  • a particularly great disadvantage of the plates described is that their fibers run in parallel planes, so that the risk of delamination is great. Furthermore, since the top layer covers the broken mineral fibers, it is also not possible to bond these fibers to the plaster to be applied. There is therefore a risk that the plaster will peel off. Furthermore, breaking up the fibers in the area near the surface, as is required for the production of the coating, is also disadvantageous because the plate loses mechanical strength as a result.
  • the binder for producing the plaster base layer should not have to contain fillers which cover the markings made on the plate. In particular, there should also be no need to break fibers in the region of the mineral fiber plate near the surface during the production of the plaster base layer and thereby weaken the plate.
  • the plate should also have the property of easily adapting to the unevenness of the wall when applied to the building.
  • the invention is based on the method according to CA-B-1 057 183, in which method the mineral fibers are provided with a binding agent to form a mineral fiber layer.
  • the mineral fiber layer is split into at least two partial webs, at least one of the partial webs is compressed, the compressed partial web is fed to the or the other partial webs, and the partial webs are combined by curing the binding agent to form a web which has at least one layer of has high density and a layer of low density.
  • the invention is characterized in that the mineral fiber layer is subjected to longitudinal and vertical compression before being split into partial webs and that after the partial webs have been combined into one web, the free surface of the layer of high density is impregnated with an impregnating agent suitable as a plaster base.
  • the plate Since in the plate produced in this way, many fibers lie inside the plate differently than horizontally, ie at an angle to the plate surface, the plate has a high tensile strength and compressive strength transverse to the plate plane. Therefore, it is not easily prone to delamination.
  • the arrangement of the fibers described also has the advantage that the binder suitable as a plaster base easily penetrates into the plate surface. It is therefore not necessary to break mineral fibers when impregnating. This in turn also enables gentler processes than pressing in with a roller, as is required in the prior art. Since the surface area to be impregnated has a high fiber density, the gaps between the mineral fibers are small, so that there is no need to include such gaps fill in ground mineral fibers. There is no need for fillers.
  • the impregnation layer can be kept relatively thin, so that the impregnation agent requirement is small.
  • the fiber requirement is also relatively small because the plate can have a relatively thin layer of high density and a relatively thick layer of low density, so that the average density can be kept small. Thanks to the relatively small density, the plate also has a high insulation effect.
  • the lack of a top layer has the advantage that fibers protrude from the impregnation layer and ensure good adhesion of the plaster when the plaster is applied.
  • the impregnating agent suitable as a plaster base is advantageously sprayed onto said free surface. This has the
  • the advantage is that the surface remains rougher than when rolling in.
  • the alignment of the fibers is not disturbed, so that many fibers also protrude from the impregnation layer formed. A rough surface results in better adhesion of the plaster.
  • the web is advantageously passed through a zone in which there is a vacuum under the web, which promotes the penetration of the impregnating agent into the region of the layer of high density close to the surface.
  • negative pressure it proves to be advantageous that the plate has a relatively thick layer of low density and the layer of high density can be kept relatively thin. A relatively low negative pressure is therefore sufficient to achieve the desired suction effect for penetration of the impregnating agent to the desired depth.
  • an overpressure can be applied over the web to promote the penetration of the liquid impregnation agent.
  • Colloidal silica is advantageously used as the impregnating agent, which is suitable as a plaster base. This impregnating and binding agent offers no problems in terms of compatibility with the mineral fibers and is also water-resistant.
  • the invention also relates to a device for carrying out the method with a first conveying device for receiving mineral fibers wetted with binder in order to form a mineral fiber layer and for conveying the mineral fiber layer to a continuous furnace at a first speed, a separating device for splitting the mineral fiber layer into at least two partial webs , a compacting device for compacting a partial web, a guide for returning the compacted partial web to the or the other partial webs, a second compacting device for further compacting and combining the supplied partial webs, a continuous furnace and is characterized in that a pre-press for reducing the mineral fiber layer conveyed to the first conveying device is provided, that a second conveying device is provided, which the pre-pressed mineral fiber layer with a reduced z promotes high speed that there is a guide-free section between the pre-press and the second conveying device, which is dimensioned such that the mineral fibers are mutually bulged and that an application device for applying an impregnating agent to the compacted partial web or to
  • a marking device can be arranged after the continuous furnace. This can be used, for example, to attach a grid as a cutting aid for the panels. It is also possible to provide a perforating device, for example a spiked roller, for perforating the web surface after the continuous furnace. As already mentioned, perforation enables the plaster to be anchored particularly well on the mineral fiber plate.
  • a device for generating a vacuum under the web is expediently provided at and / or after the application device. The penetration depth of the impregnating agent can be regulated according to the requirements by generating a suitable negative pressure. However, it is also possible to provide a device for generating an overpressure above the web at or after the application device in order to control the penetration of the impregnating agent.

Abstract

La plaque de fibre minérale fabriquée selon le présent procédé a un faible poids volumique moyen et ne nécessite donc que peu de matériau fibreux. L'imprégnation est obtenue avec de faibles quantités d'acide silicique colloïdal et fournit une bonne couche de support pour enduit. Lors de la fabrication de la plaque, une couche de fibre minérale (11) est soumise à une compression en longueur et en hauteur et ensuite divisée en deux bandes partielles (35, 37). La première bande partielle (35) est comprimée, puis de nouveau amenée sur l'autre bande partielle (37), et réunie avec cette dernière pour former une seule bande (49) dans un four continu (45). Ensuite, la surface de la couche de haute densité (35'') est aspergée au moyen d'une buse (51) avec un produit d'imprégnation. Dans la zone (53), une dépression aspire le produit d'imprégnation qui pénétre dans la zone proche de la surface (57).
