Definitions

  • the invention relates to a method for producing a mineral wool insulating board, in which the fibers have a rectangular course to the large surfaces.
  • the invention relates to an insulation panel for thermal insulation composite systems with a right angle to the large surfaces aligned fiber profile.
  • external thermal insulation systems consist of an insulating layer, which is applied to load-bearing walls of a building with the help of adhesives and / or insulation holders.
  • the insulating layer here consists of individual thermal insulation panels, which are covered with two layers of plaster, wherein the first layer of plaster can be reinforced with a glass fabric or the like. On this first layer of plaster, a top coat is applied. This top coat can also be formed from small plates made of plastic or heavy clay.
  • polystyrene hard foam insulation panels have proven that have a compressive and transverse tensile strength of more than 100 kN / m 2 . These panels are partially or fully glued to a suitable substrate. Disadvantage of this polystyrene foam insulation is that they behave in thermal insulation systems such as normal flammable materials, so that increasingly non-combustible plaster base insulation materials, such as cellular concrete are used.
  • Such plaster base insulation materials can have densities between 100 and 250 kg / m 3 and are sufficiently stable with a thermal conductivity of 0.050 W / mK.
  • these plaster base insulation materials Compared to mineral wool insulating materials, these plaster base insulation materials have the disadvantage that they have a higher brittleness and breakage sensitivity during transport and application. Furthermore, the high swelling and shrinkage behavior of these materials after wet exposure is disadvantageous. It comes here to cracks in the applied plaster. To avoid these disadvantages and to ensure a sufficient transverse tensile strength even when wet, these materials must be adequately hydrophobed.
  • thermal insulation systems mineral wool insulation materials in the form of plates or so-called lamellar plates.
  • the normal as a plaster base plate to be designated mineral wool insulation board characterized by the fact that they undergo intensive production in the direction of production by a horizontal compression in conjunction with significantly lower vertical pressure (thickness compression).
  • the fibers are located near the large surface parallel to them.
  • this orientation causes a significantly lower transverse tensile strength against the core region of the insulation board, in which the fibers are arranged more or less steeply to the large surfaces.
  • the transverse tensile strength is further reduced by the fact that the insulation board also has a predominantly laminar structure of the horizontally mounted individual fibers transversely to the production direction.
  • the average density of these plaster base plates is about 120 to 180 kg / m 3 , preferably about 150 kg / m 3 . Due to the unfolding of the individual fibers, the compressive strength increases to the required minimum of greater than or equal to 40 kN / m 2 . The transverse tensile strength hardly exceeds about 17 to 27 kN / m 2 due to the structural character just described. Such thermal insulation panels reach the thermal conductivity group 040 according to DIN 4108.
  • lamellar plates Other mineral wool insulation materials are designed as so-called lamellar plates. These insulation boards have fibers with a steep or vertical arrangement relative to the large surfaces.
  • the production of such lamellar plates is for example in the DD 160 817 described.
  • the pulp mass flow impregnated with binders is cut into short pieces, which are rotated by 90 degrees and then pressed horizontally, ie in the direction of production, again and connected to one another. At the same time, the fiber mass is compressed by 20%.
  • the structure obtained in this way is fixed by curing the binder in a hardening oven.
  • a product is prepared in which the individual fibers are arranged in the near-surface areas parallel to the surfaces, so that these insulation boards also do not reach the full transverse tensile strength of the core area. Due to the smaller thickness of the outer zones in which the fibers are horizontal and the comparatively higher densification of the fibers, these insulating panels have a higher transverse tensile strength of 30 to 45 kN / m 2 . For the use of mineral wool insulation boards with composite thermal insulation systems, there is moreover a request to the transverse tensile strength of at least 15 kN / m 2.
  • Thermal insulation systems based on such plaster base plates must be secured with a relatively high number of insulation holders. These insulation holders are usually made of a plastic plate with a shaft that terminates in a dowel. With the help of a screw, the dowel is spread and anchored in the load-bearing wall of the building. After the plaster base plates are anchored to the building, the plaster base plates are first held by the shaft and screw of the insulation holder. After application of the plaster layers, the insulation holder must also hold these components of the thermal insulation composite system.
  • the bonding is disregarded.
  • the bonding of the insulating panels on the building is therefore considered only as an assembly aid and not as a fixture.
  • the insulation holder but are disadvantageous due to their unit prices and the associated assembly in comparison to only glued plaster base plates.
  • Dämmstoffhalter form additional politicians brükken, which reduce the heat resistance of the thermal insulation composite system because of their large number.
  • the insulation holder can be seen in low plaster coverage or as a result of different Feuchegehalte in the top coat, so that a uniform surface is not given.
  • the lamella plates described above are used.
  • the individual fibers are arranged predominantly perpendicular to the large surfaces, so that transverse tensile strengths of significantly more than 100 kN / m 2 are achieved at densities of only 75 to 100 kg / m 3 .
  • the transverse tensile strengths of more than 80 kN / m 2 necessary for stability can still be achieved.
  • the maximum width of the slat plates produced in this way is identical to the maximum thickness of the plaster base plate and is approximately 200 mm. Even on condition that this thickness, i. the passage height of the curing oven could be raised, this would result in an adverse effect on the strength properties of the lamella plates. Namely, it is known that with larger thicknesses of the mineral wool slabs comes to a different compression of the fiber masses over the height, which then has a negative effect on the uniformity of the transverse tensile strength in the surface of the slat plate.
  • Lamellar plates are relatively small in the usual dimensions of 1000 to 1250 mm in length and 200 mm in width. This results in many joints between the individual slats, which are arranged side by side on the facade of a building. These joints reduce the thermal resistance of the insulating layer. Furthermore, it has proved to be disadvantageous that the dimensional accuracy of the supplied lamellar plates is dependent on the accuracy of the saw used for separating the plaster base plate. Thickness tolerances between the individual lamella plates of 1 to 2 mm are therefore not uncommon. The craftsmen processing these lamellar plates therefore have to compensate for projections in the laying of the lamellar plates, which leads to higher processing costs due to the time taken to work.
  • the invention thennenga be based on providing a method for producing an insulation board, with the simple and cost-effective manner large-sized insulation boards with perpendicular to the large surfaces arranged fiber profile for thermal insulation systems can be produced, which avoid the disadvantages mentioned above ,
  • the object is achieved with a method according to claim 1 or an insulating panel according to claim 14.
  • individual nonwoven layer sections are produced, for example, by an oscillation about a horizontal axis.
  • the individual nonwoven layer sections are formed here from a primary nonwoven layer.
  • a primary nonwoven layer is understood to be the pulp mass flow impregnated with binders and discharged from the so-called collection chamber.
  • the fibers, originally oriented substantially parallel to the large surfaces of the primary web, are brought to the large surfaces by swaying the nonwoven layer sections in a steep to rectangular manner.
  • the primary nonwoven layer is thus aligned meandering by the pendulum, wherein adjacent nonwoven layer sections are connected to each other via a bent portion.
  • the primary nonwoven layer on roller sets and / or horizontal dynamic pressure to meander meandering.
  • the conveying speed of the primary nonwoven layer in a section of a continuous conveyor can be reduced so that the primary nonwoven layer running up at a higher speed builds up meandering in this area of the lower conveying speed.
  • Suitable binders which can be introduced both into the primary nonwoven layer and between the nonwoven layer sections are, for example, phenol-formaldehyde-urea mixtures.
  • ormocers have also proved to be suitable binders under the practical conditions of construction.
  • the binders are stable both under the hygrothermal conditions prevailing in the component and resistant to the alkali attacks from the adhesive mortars, building adhesives and plasters.
  • the inorganic binders consist of organic silicic acid compounds whose colloids have diameters of only a few nanometers. Subsequent thermal treatment converts the sol into a gel and ultimately into insoluble silica.
  • these areas close to the surface are separated, for example, by sawing and / or grinding. It has proven to be advantageous to separate the near-surface regions, in particular on the large surface, which is glued to the supporting substrate, thus with the building.
  • the insulation boards produced by the process according to the invention have densities between 60 and 180 kg / m 3 . In a gross density range between 80 and 100 kg / m 3 , both transverse tensile strengths of more than 60 kN / m 2 and low thermal conductivities are achieved. With the method according to the invention, moreover, insulating panels of larger sizes can be produced in a simple manner, which allow a faster laying of the insulating panels on building facades.
  • the general arrangement of the individual fibers within the insulation board also has the consequence that the insulation board in the production direction has a significantly lower bending strength and shear stiffness than transversely to the production direction, so that the insulation board can also apply to curved surfaces, of course, the thickness of the insulation board and the Radius of curvature are of significant influence.
  • insulation boards are produced which have at least one surface which corresponds to a surface of a lamella plate, since the bent region of the primary nonwoven layers are removed.
  • This embodiment has the advantage that the incorporation of building adhesives and plasters can be done much deeper into the surfaces.
  • adhesives and putzaffine masses such as water glass plastic-filler mixtures, adhesive mortars, plastic dispersions, silica sol-filler mixtures or the like are introduced as a coating .
  • This coating of at least one large surface with adhesives and putzaffinen deeply anchored in the fiber mass not only results in significant processing advantages, but also imperfections customary in the construction industry are eliminated, which leads to an increase in the stability of the entire thermal insulation composite system. It has been proven that the incorporation of building adhesives and plasters on the site is a time-consuming and exhausting operation. This procedure could be facilitated by the fact that adhesives and plasters are made thin.
  • the insulation boards produced and coated according to the invention can be pressed into the adhesive layers applied mechanically on the entire surface or even only over part of the area on the supporting substrate.
  • the plaster-side coating of the insulation boards leads to a secure bond with simultaneously increased processing power.
  • the adhesive and plaster-rich masses in the two large surfaces differently colored to facilitate the processing of insulation boards to the extent that the craftsmen the correct orientation of the insulation boards is displayed.
  • the coating of colloidal silica is introduced via a sol-gel process.
  • the longitudinal axis of the insulation board coincides with the original production direction of the primary nonwoven layer, so that the longitudinal direction of the individual nonwoven layer sections is arranged substantially perpendicular to the longitudinal direction of the insulation board.
  • the advantage is achieved that the dead load of the thermal insulation composite system can be safely absorbed by the shear stiff orientation of the individual fibers.
  • the shear stiffness of the insulating layer can also be increased in the horizontal direction by a deliberate change of the axis direction of the insulation boards during installation.
  • the insulation boards Since the insulation boards must be laid in a bandage, it is advisable to set the width of the plate to half the length or to use square plates in such a laying. In order to perform this oriented laying on the site, the insulation boards are provided according to the invention with suitable markings.
  • the insulating panels circumferentially have a groove for inserting profiles made of metal or plastics, which in turn are attached to the supporting ground.
  • the insulation panels can be used in known per se thermal insulation systems with rail fastening systems.
  • the load-bearing rails run horizontally, while the vertical rails only serve to avoid jumps between the insulation boards.
  • the insulation panels are installed so that the axis of their greater continuity extends transversely to the supporting rails, so as to cause the greatest resistance to the occurring load cases (dead load and wind suction).
  • a coating is applied, which preferably consists of water glass plastic-Füllstoff-Gemsichen, adhesive mortars, plastic dispersions, silica sol or filler mixtures.
  • the coating consists of an initially aqueous mixture of 2 to 35% by mass of aluminum phosphate, 2 to 35% by mass of phosphoric acid, 10 to 80% by mass of filler and at most 0.1% by mass of surfactants, which are preferably nonionic.
  • fillers for example, oxides and hydroxides of magnesium, calcium, titanium, aluminum are suitable. But it can also be used Ca feldspars, mica, chamotte or brick flour and Traß.
  • An alternative coating consists of colloidal silica.
  • the coating may consist on the side facing the building wall of a maximum of 5 mm thick mortar layer and on the plaster surface of a thin, easily severable with the knife or saw coating.
  • the mortar layer is preferably bonded with microfine ground Portland cement or alumina cement with the addition of up to 8% by weight, preferably 2.5 to 8% by weight of plastic dispersions and, for example, styrene-butadiene copolymers, styrene-acrylic copolymers.
  • This embodiment has the advantage that after severing the outside coating and the insulating material, the mortar layer can be easily broken.
  • the outside arrangement of the mortar layer has the advantage that the susceptibility of the plaster layer is reduced against cracks by the now shear-resistant surface.
  • this has a compressive stress of more than 40 kN / m 2 .
  • shear strengths are provided in the insulating panel according to the invention, the greater in a first direction, preferably the longitudinal direction of Dämmsstoffplatte 20kN / m 2 and in a second, perpendicular to the first direction direction, preferably transverse to the direction of production equal to 60 kN / m 2 be.
  • Such insulation board is particularly suitable for the application examples described in thermal insulation systems to absorb the loads occurring, namely wind suction and dead load.
  • insulation board 1 for a thermal insulation system 8 consists of a section of a mineral fiber fleece 2.

  • FIG. 1 In this context is off FIG. 1 to recognize that the length of an insulating panel 1 is twice as large as the width of the insulating panel 1, wherein the longitudinal axis of the insulating panel 1 coincides with the original production direction of the primary web. Since the insulating panels 1 are laid longitudinally on the supporting ground, namely a building exterior wall, the dead load of the thermal insulation composite system 8 can be safely absorbed by the shear stiff orientation of the individual fibers. At the same time, the shear stiffness of the insulating layer can also be increased in the horizontal direction by a targeted change of the axis direction of the insulating panels 1 during installation. Such an arrangement of the insulating panels 1 is in FIG. 3 shown. In order to lay the insulation panels 1 in association, they can either be formed with the above dimension, ie with respect to the width double the length or as square plates.
