Definitions

  • the invention relates to an insulating element made of mineral wool in a composite design a laminated layer, the grain of which runs counter to the direction of the major axes of the element is oriented vertically and in a continuous production process manufactured, 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 soothes in a suction chamber without the addition of binders, are combined into a thin nonwoven fabric and are then conveyed from the suction chamber into a completely separate spraying and collecting chamber, in which the thin fiber fleece dissolves after leaving the suction belt or an intermediate transfer belt and moves downwards in the form of individual fibers and / or fiber agglomerates by gravity, sprayed with binders during the free fall via binder nozzles and then on a collecting belt for one Further processing is 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 with which it is possible to produce multilayer products from mineral fibers, 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 a predominantly vertically oriented fiber orientation of the mineral wool products when laminating mineral fiber nonwovens.
  • the solution of this patent ensures the manufacture of products whose grain direction 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 insulation 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 layer of air is arranged between the insulation layer and the barrier coating.
  • DE OS 42 19 392 further discloses a thermal insulation board 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 bulge-like 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 an insulating element made of mineral wool in composite design with a layer laminated from mineral wool, the course of the fibers opposing it the direction of the major axes of the element is oriented vertically and in a continuous production run, a selective coating of its Preserves surface as well as creating a process for its manufacture, which besides a versatile usability, comprehensive structural requirements, strength properties, high dimensional stability, good sound absorption and increased resistance against thermal and weather-related loads in an aesthetic training has its surface.

  • 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 fiber rows. 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 fiber direction, 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 also opposed to low linear expansion and creeping capacity with lower density are assigned.

It is now possible to produce a non-combustible product with outstanding fire protection properties 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 used as an independent building element in a building or when it is to be used for multifunctional 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 so 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.

  • Material, between layers of highly compacted or slightly compacted materials, give the person skilled in the art 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 uses and is endowed with excellent physical properties.
  • the invention is designed when the web groups of the perpendicular webs are formed from 2 to n times repeating groups of a non-similar 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 .
  • the deliberate integration of materials with high fire prevention classes allows the universal usability of the elements not only in the building industry, but also in shipbuilding, vehicle construction and much more.

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.
  • a silicate material is selected and determined for the coating of the insulation elements. It is in the broader sense of the invention if the coating, determined as the carrier layer of a final top layer to be applied separately, is designed to be open to diffusion. Shaping the invention, the coating can be provided as a final cover layer, colored.
  • a feature embodying the invention is the tear resistance of the coating, which ranges 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 surfaces. 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.
  • 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 run over 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. This opens up possibilities for the specialist to produce consistently laminated, coated insulation elements up to a width of 2400 mm, which in their longitudinal limitations alone have to meet the requirements of the building.
  • the consistently glue-free lamination ensures a high degree of fire safety, even with a surface coating, since according to the invention the layer is made of a non-combustible, silicate material.

  • the fiber shafts are gripped to a depth of up to 1.5 mm into the surface of the insulation element. This also ensures that the treated element is coated throughout and that the layer has a high resistance to tearing on the insulating element.
  • The, measured by the fiber length, perpendicular to the surface close to tightly stretched fibers ensure a high level of adhesion, but ensure that the coating substance used for coating advantageously, here a highly viscous, curing silicate mass, cannot penetrate deeper into the fiber interstices and one creates a heterogeneous structure of the insulation element and on the other hand the insulation effect is impaired by clogging of the air gaps between the fibers.
  • the expert reading along will of course understand that 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.
  • the advantageous use of a silicate material ensures compliance with the basic requirement for insulating elements of this type, to ensure advantageous fire behavior.
  • the silicate coating is non-combustible and avoids the formation of harmful gases when used in industrial and residential buildings.
  • the advantage of the insulating element presented according to the invention is further expanded by the fact that the coating is advantageously used as a top or bottom layer, is designed to be extremely open to diffusion, and allows the building structure excellent ventilation of its building surfaces. This advantage results in further progress according to the invention.
  • the coating also or above all as a silicate layer, can be used especially as a carrier layer for a layer of plastering mortar, since it is extremely easy to connect to the plastering mortar and, thanks to its excellent diffusion properties, ensures that all building layers are ventilated.
  • the use of colored coatings with the same physical properties as mentioned above emphasize the aesthetic effect of the building through its color design and the aesthetics of the surface design.
  • the concept which is advantageous according to the invention guarantees the production of coated elements with molded-on surface parts which are also chamfered, rounded and surface-shaping. Taking into account the inventive concept, the coating can also be carried out when the elements on the production line of the system have been cut and edge-processed and still lie close together on the line. As a result, circumferential chamfering, rounding or refinement of the edge formation are also detected and the surfaces of the elements are completely covered by the coating.

  • 9 shows an example of an intermediate layer 13 with a fibrous structure, the fibers of which run horizontally to the major axis of the element and granules are embedded between the fibers.
  • 10 shows the layers 14; 15 with a minimal thickness. Between the layers 14, 15, 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. This is the case when, for example in the case of dry buildings, low weights of the elements are required for partition walls and the components used for this purpose must have a high dimensional stability and a low resilience.
  • 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.
  • FIG. 9 to 11 given the technical information that the base and cover layers 11, 12 of the insulation elements 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 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.
  • the known method for producing mineral fiber nonwovens with a predominantly vertically oriented fiber orientation, using laminating mineral fiber nonwovens creatively, laminated, vertically oriented webs 20 made of mineral fibers with webs 19 are materials of the same type, but of a different structure, as groups 21 merged, manufactured.
  • the insulating elements assembled from these web groups 21 with a selected thickness and number of layers according to the invention have excellent static properties and are recommended for use in different areas, for example construction, shipbuilding, vehicle construction and steel container construction.
  • 19 presents an insulation element 34 with a surface coating 35, to which chamfers 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 small 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.
