Definitions

  • the invention relates to an insulating element made of mineral wool in a composite design with a laminated layer, whose fiber course is oriented vertically against the direction of the major axes of the element and into one continuous production pass, selectively receives a coating on its surface and a process for its manufacture.
  • DE 1 945 923 A1 discloses a flat structure, e.g. B. for use in building protection for roofing or for insulation purposes.
  • the two-dimensional structure consists of a tangled nonwoven, preferably of continuous filaments, which either enclose a protective and insulating mat between them or only by a surface layer of the same mass, which preferably has nonwoven filaments fused together at their crossing points.
  • This mat or this flat structure has the disadvantage that it probably has nonwovens with different properties in a layered structure.
  • the disadvantage here is that the nonwoven formation lacks strength in the dimensional stability.
  • the density and tear resistance of the fleece is insufficient and can only be used for insulating mats in a limited area.
  • DE 42 22 207 C2 discloses a method for producing mineral fiber products and an apparatus for carrying out the method.
  • the solution according to the invention is aimed at obtaining, in the production of mineral fiber products with compacted surface areas from mineral fiber webs, in which the fibers within the mineral fiber web run essentially parallel, perpendicular or obliquely to the large surfaces of the mineral fiber webs, the mineral fiber webs containing an uncured binder .
  • a high tear resistance and an intensive fiber composite should be achieved between the compacted surface areas or layers and the remaining part of the mineral fiber web.
  • the solution according to the invention in accordance with this method is aimed at matting the fibers in the surface areas on at least one surface area by means of needle strokes up to a predetermined penetration depth and at the same time compacting them.
  • This process permits continuous production of the mineral fiber products and also has a different structure with compacted edge areas of the mineral wool product.
  • the mineral wool bodies or elements made therefrom have a low tear-off strength and dimensional stability. It is only attempted by means of this method to improve fiber products which are not densely compacted by the basic substance and which are insufficiently homogeneous in their fiber course for a higher-value use.
  • DD 297 197 B5 discloses a method for the loss-free introduction of binders into mineral fiber nonwovens, in which the fibers calm in a suction chamber without the addition of binders, are combined to form a thin nonwoven fabric and are then conveyed from the suction chamber into a completely separate spraying and collecting chamber which dissolves the thin fiber fleece after leaving the suction belt or an intermediate transfer belt and moves downwards in the form of individual fibers and / or fiber aggregate minerals due to gravity, sprayed with binders during the free fall via binder nozzles and then on a collecting belt for further processing accumulated in the required thickness and continuously transported.
  • the method according to this invention is currently the most advantageous method for wetting raw fiber nonwovens with binders, but has the disadvantage that only one layer of fibers provided with binders can be sucked onto the collecting belt at a time.
  • a method and a device have been found in which it is possible to produce multilayer products from mineral lasers, in which the layers are designed differently. The differences in the layers are reflected in a differing density, strength and type of material.
  • the process is fundamentally based on DD 297 197 B5, basically uses the solution according to the invention and expands it in such a way that not only is it now using the substantiated process of the basic patent one layer, but several and also different layers combined in a mineral fiber product, can be produced continuously.
  • DD 248 934 A3 now discloses a method and a device for producing products with predominantly vertically oriented fiber alignment of the mineral wool products when laminating mineral fiber nonwovens.
  • the solution of this patent ensures the production of products whose fiber orientation is perpendicular to the major axes of the product.
  • it only permits the production of products whose fiber course is arranged uniformly without interruption, oriented vertically with respect to the major axes of the element.
  • the element made from the laminated nonwoven fabric only along its slats oriented transversely to the longitudinal center axis, has great flexural rigidity, but has a reduced resistance to bending in the direction of its longitudinal center axis.
  • the visible surfaces are covered with coating agents that have an aesthetic effect, but are not fire-retardant and, in the event of fire, impair the effect of the insulating element on the building.
  • DE 42 10 393.C3 discloses a component with a vapor barrier, which disadvantageously avoids the diffusion process, even if a thin air layer is arranged between the insulation layer and the barrier coating.
  • DE OS 42 19 392 further discloses a thermal insulation sheet made of rigid plastic foam in which the impregnating or coating agent has a differently determined water vapor transmission resistance than that of the base material of the thermal insulation board. With a development of this kind, the disadvantage of the prior art cannot, of course, be eliminated.
  • WO 95 33 105 discloses a method for gluing the cut surfaces of mineral wool, in which, in particular, lamella plates made of this material are glued to an adhesive base with an adhesive.
  • the cut surfaces are first precoated over the entire area with a thin adhesive or an aqueous plastic dispersion and, after setting, applied with point and / or bead-shaped adhesive and bonded to the substrate.
  • This two-layer process can also be carried out by machine.
  • a disadvantage of this method is that due to the development of the production possibilities of laminated mineral wool panels with a vertical grain, only relatively small-format panels with a width of up to 200 mm can be produced.
  • the term "large format" is used here in the font for the length, so that the format cannot exceed a width of 200 mm, even with long lengths. It is therefore not possible to apply coatings that are open to diffusion on both sides of the element, as seen from the large surfaces.
  • the document also gives no information about how deeply the aqueous plastic dispersion used penetrates into the lamellae and thus impairs the diffusion effect and the insulating properties of the element.
  • ALSECCO a mosaic flake coating system is known. The coating takes place in three stages, a dispersion base coating, a decorative mosaic coating and the final coating for the mosaic system.
  • This type of coating allows both the coating of individual insulation elements before they are attached to the building walls and the complete coating of already insulated walls on their visible surfaces. It is to be regarded as a disadvantage that, despite the recognizable high aesthetic effect of the coating, the diffusion properties of the buildings are impaired. Another significant disadvantage is that the coating composition is not fire-retardant and the fire behavior of the structural parts coated with it is adversely affected.
  • the invention has for its object to provide an insulating element made of mineral wool in composite design a layer of mineral wool laminated, the fiber course against the direction of the major axes of the element vertically oriented and manufactured in a continuous production process, a selective coating maintains its surface as well as a process for its manufacture, which in addition to a versatile Usability comprehensive structural requirements, strength properties, high dimensional stability, good Sound absorption and increased resistance to thermal and weather-related loads has an aesthetic design of its surface.
  • the object is achieved in that a laminated, oriented vertically in the grain trained layer, executed one or more times, with layers of the same material, different fiber course or other structured material is connected and the layer structure of the element, in Repeating one or more elements.

It is a sensible embodiment of the solution according to the invention that the layers with a laminated, vertically oriented fiber course, optionally also produced as independent, are rotated by 90 ° to their major axes, joined together and connected.
  • the invention is understood to be advantageous if at least two layers with a laminated fiber course are joined to one another and connected to one another.
  • the lamellae which are vertically oriented by means of a laminating process, form web-like rows of fibers. The rows intersect when the layer structure of the element is rotated by 90 ° and thereby create a lattice-like structure of the insulation element.
  • the insulating element with a laminated, vertically positioned fiber course is assigned on one side, which is formed by one of the large areas, to a layer which is composed of a differently formed material.
  • the material of the assigned layer can consist of a fiber material which runs horizontally in the direction of the fibers, ie parallel to the large area, and can be formed from mineral wool, glass wool, glass fleece and other materials which have properties such as good fire protection behavior, high elasticity or, in contrast, low linear expansion and creeping capacity with lower density are assigned.
  • this layer in its thickness, that is to say to apply it as a layer of the same thickness or as a very thin non-woven fabric.
  • Embodying the shape of the product according to the invention it is permitted to use granular products in the layer structure of the layer applied to the base layer or to link the material structure of the two previous solutions and to combine the layer structure by inserting granules into and between fibrous materials. So it is now possible to produce a non-flammable product with outstanding fire protection switches in the highest fire protection classes.
  • This product also has the property of being used as a separate, structurally functioning construction element due to the extremely dimensionally stable, laminated base layer with a vertically oriented fiber orientation.
  • the material configuration of additionally applied layers already shown is also advantageous according to the invention if the layers are applied to both large surfaces of the laminated layer. It is possible, for example, to apply effective layers on one side of the laminated element in an acoustically insulating manner, while a plaster base with, for example, a layer of ceramic products is arranged on the other side.
  • the basic configuration is useful when the element is to be used as an independent building element in a building or when it is to be used for multi-functional loads. It is therefore advantageous according to the invention that the assigned layers have a multi-layer structure and are equipped with the same or different structure or material composition.
  • the layer in the element with a laminated, vertically oriented fiber course is formed by one or more layers which are arranged by top or bottom layers and are connected to intermediate, differently formed materials.
  • the top and bottom layers are arranged in such a way that they can accommodate one or more intermediate elements which are designed as layers and are firmly connected to the outer layers.
  • the inventive design of the composite insulation elements advantageously has an extremely compact, dimensionally stable design. So it is also possible to produce layered insulation elements of great thickness, which can be used as wall elements in drywall construction, have high insulation properties, have excellent workability because they can be easily joined and inserted horizontally and vertically.
  • the invention is advantageously designed when the element has intermediate layers which are arranged as ventilation ducts and allow horizontal and vertical ventilation of the walls of the building.
  • the ventilation ducts are now arranged directly between the bottom and top layers of a laminated, vertically oriented fiber course or can be embedded in materials.
  • the bedding material can be a fiber material or a granulated structure.
  • the invention finds a very advantageous embodiment in that the element has a laminated layer with a vertically oriented fiber course, based on the extension of its large areas from perpendicular to it, formed from segment-shaped, web-like layer groups that repeat themselves in the layer plane, the Material structure and composition was not designed in the same way.
  • These products represent an extremely advantageous development of an insulation element with the consequent application and further development of the products that can be manufactured using the solutions listed in the prior art.
  • the product initially available in one layer, combines vertically placed groups of different material structures in the fiber structure with a web-like, vertical layer structure, whereby predominantly web-like layers of a vertical fiber course are connected with web-like layers of differently structured materials and form a flat insulating body.
  • the layers advantageously designed, run transversely to the longitudinal center axis, so that a web-like, vertical layer formation is repeated, which is repeated in groups.
  • An insulating element of this structure has previously unknown advantages.
  • the insertion of web-like layers with a non-combustible material of high fire protection classes, such as glass fibers, glass fiber fleece, etc. Material, between layers of highly compressed or less compressed materials give the expert the indication that, in addition to high dimensional stability and above-average good processability, an element has been invented which has a wide range of applications and is endowed with excellent physical properties.
  • the invention is designed if the web groups of the perpendicular webs are formed from 2 to n times repeating groups of a non-uniform structure of the material and its composition. It is advantageous according to the invention and in the sense of the tenor of the solution according to the invention that the repeating groups, within the framework of the webs, have different strengths and consistencies, webs with great strength, in addition to webs with low strength, being formed and the element can be assigned by the webs with high strength, high compressive strengths, great dimensional stability, a reduced resilience.

It follows the logical consequence of the solution according to the invention that the webs thus formed are formed with unequal strength and density in the area of superimposed webs with lower density, continuous lines of force with lower strength, and lower density with a high resilience and great insulation effect in the layers with uneven layer structure .

At the apex, the supplied multi-layer non-woven fabric is cut into lamellae.
  • the separated lamellae now form assembled layer arrangements of a fleece which has web-like lamella arrangements which form corresponding web-like lamella groups in terms of the number and material composition of the layers, which are pushed onto the support and removal device during separation and from there to form a uniform element having several layer groups continuously processed. It is sensible to selectively define insulating elements on their large surface to be coated with another material that improves their aesthetic effect. In a previously determined assignment, only the elements whose surface or upper layer have a fiber course that is oriented perpendicular to the major body axes of the elements should be coated.
  • the surface of the insulation element selected for coating is provided with a coating in a width range from 230 to 2400 mm, with a variably selectable length limitation of the nonwoven fabric passing through the production line, on the cross-sectional areas of the fibers running perpendicular to the major axes of the element, the fiber shafts of which have a shallow depth, with the same high tear-off strength as that of the insulating element in the range from 40 to 100 kPa.
  • the invention is designed when the limitation of the length of the insulating element after the coating of its surface is adapted to the technological requirements of the construction. It is within the meaning of the invention that the coating is formed from a non-combustible material.

Embodying the invention is the tear resistance of the coating, which is located in a range from 60 to 80 kPA. The invention is advantageously embodied in that the coating is guided over a lateral chamfering of the peripheral edges up to the outer region of the vertical side streams.
  • the solution according to the invention offers the user the advantage that the surfaces selected for coating can now take place directly in the production process of the mineral fiber fleece in the system. Since the nonwoven can stand up to a width of 2400 mm in the production facility and is used in a laminated manner in the present case, a surface coating over the entire width is already carried out on the conveyor belt during the continuous process in the final production stage of the nonwoven.
  • the selectable length limits will no longer be subject to any objective restrictions because the nonwoven fabric to be coated coming from the continuous production line allows the production of any lengthwise insulation elements up to a width of 2400 mm. Due to the continuous coating during the production cycle across the entire width of the fleece, the length limitation is now only determined by the technological requirements that the building places on the insulation elements.

  • the penetration depth of the coating medium that is to say the embracing of the fiber shafts, is not detrimental to the solution according to the invention even over a range of 1.5 mm, but a penetration depth of 2.5 mm should not be exceeded, since otherwise the elasticity and the yield strength of the surface of the element is adversely affected.
  • the measures introduced according to the invention have the advantage that the tear resistance of the coating can be achieved just as high as the tear resistance of the entire insulation element, it being in a pragmatic range if 60 to 80 kPa are assumed for the tear resistance.

  • a wave-like layer 16 is inserted, which can be made of a dimensionally stable material, such as sheet metal, plastic film or glass fiber laminate.
  • the wave-shaped design of the layer 16 allows the formation of ventilation spaces 17.
  • the intermediate layer 18 is formed from a granular material which, for example, can have high heat resistance with resistance coefficients against ignition, such as a greatly retarded flammability. Ventilation spaces 17, which are located in the region of the neutral fibers, are arranged in this material.
  • FIGS. 9 to 11 give the technical information that the base and cover layers 11, 12 of the insulation panels can also be arranged offset to one another. 9a, the lamellae of the cover layer are shifted by half a lamella relative to the base layer and thus form a composite design, since the connecting joints of the lamellae are no longer perpendicular to one another. 12 and 13 show a laminated element a configured with a predominantly vertical fiber course.
  • the element a has groups 21 of vertical web-shaped layers 19; 20 which have a different material composition, the groups 21 being able to repeat themselves cyclically or acyclically.
  • the element a can be formed in different thicknesses and is applied in accordance with the lambing method.
  • DD Patent 248 934 A3 which in its creative application according to FIG. 18 is to find even more detailed explanations, according to the solution produced by a patent application which extends the patent.
  • the groups 21 are designed differently in their web-shaped layers 19; 20.
  • the webs 19, 20 are composed differently in their material compositions, the webs 19 being predominantly formed from a fiber material with a vertically oriented, laminated fiber course.
  • the web (s) 20 can be given a different material composition from one another.
  • 15 shows the arrangement of the webs 19, 20 in the layers 22; 22 '.
  • the half-section shows that the lower layer 22 ', as seen in the plane of the table, has vertically oriented web groups 21 and the overlying plate has web groups 21 which are rotated by 90 ° thereto, so that here, as also shown in FIG. 16, a cross-lattice-like structure there are alternating overlapping web groups 21 of webs 19 of vertically oriented fiber course and webs 20 of different types of material.
  • the reading specialist now receives the information that an insulation element for absorbing large static loads and excellent physical properties, such as insulation and fire protection behavior, has been created.
  • the end and side surfaces can be provided with tongue or groove-like fixing elements which fix the elements independently in their position or also take up mortar or adhesive to the elements in line with the wall on their end and side surfaces connect with each other.
  • the fixing elements are not shown separately in the drawing because they can be very diverse and are also known per se to those skilled in the art.
  • FIG. 17 shows the production of the web-like web groups 21 of the insulation element.
  • a roller table consisting of rollers 28, 29 is fed a raw fiber fleece 23 formed from three layers 31; 32; 33 and compacted in accordance with the known method.
  • FIG. 19 presents an insulation element 34 with a surface coating 35, to which bleedings 36 are assigned at the edges. As shown in more detail in FIG. 20, the coating 35 extends over bevels 36 to the edges of the side surfaces 38.
  • the element 34 can have a width of up to 2400 mm and its length is due to the continuous formatting and coating on the production line, kept variable. It has a rectangular formatting, but can take on any geometric, areal shape, depending on the technological conditions of the building. 20 shows that the fiber course 37 of the fibers of the laminated insulation element 34 is directed perpendicular to the large body axes 39; 39 '. This makes it possible for the coating 35 to include the fiber shafts 40. The shape of the embracing of the fiber shafts 40 is shown in FIG. 21.
  • a very large enlargement of a section of the coated surface reveals that the encircling of the fiber shafts 40 goes hand in hand with a low penetration depth 41 of the coating medium into the insulating element 35 and nevertheless ensures a homogeneous, gapless surface coating 35.
  • the encompassing of the fiber shafts 40 across their cross-sectional areas, the intimate connection of the coating material with the cross-sectional areas of the fibers and the properties of the coating material ensure a tear resistance that can be compared with that of the insulating material and is pragmatically at 60 to 80 kPa.
