Definitions

  • the invention relates to a method for the production of insulating elements, in particular for the thermal and / or acoustic insulation of building exterior surfaces, preferably of mineral fibers, in which an insulating material web is divided by mechanically executed cuts in strip-shaped sections. Furthermore, the invention relates to a device for the production of insulating elements, in particular for the thermal and / or acoustic insulation of building exterior surfaces, preferably made of mineral fibers, with a device for promoting an insulation web and arranged in the region of the cutting device with which the insulation web by cuts in strip-shaped sections is divisible.
  • Insulating elements are made of different materials. For example, insulating elements made of polystyrene foam are known. In addition, insulating elements are made of glassy solidified mineral fibers, which are distinguished by the chemical composition in commercial glass wool and rock wool insulation materials. Both varieties differ in the chemical composition of the mineral fibers.
  • the glass wool fibers are made from silicate melts containing high levels of alkali and boron oxides which act as fluxes. These melts have a wide processing range and can be drawn out into relatively smooth and long mineral fibers by means of rotating bowls whose walls have holes, which are at least partially bonded, at least in part, with mixtures of thermosetting phenol-formaldehyde and foam resins.
  • the proportion of these binders in the insulating elements of glass wool is about 5 to about 10% by mass and is also limited by the fact that the character of a non-combustible insulating element is to be preserved.
  • the binding of the mineral fibers can also be done with thermoplastic binders such as polyacrylates.
  • the impregnated with binders and other additives mineral fibers are collected as insulation sheet of mineral fibers on a slow-running device for promoting the insulation web.
  • the mineral fibers are oriented in a plane largely directionless and store extremely flat on top of each other.
  • the binder contained in the insulation sheet is cured in a hardening furnace by means of hot air, so that the structure of the insulation sheet is fixed.
  • the primary nonwoven consists of relatively coarse fiber flakes, in the core areas of which higher binder concentrations may be present, while weaker or even non-bonded mineral fibers predominate in the edge areas.
  • the mineral fibers are aligned in the fiber flakes approximately in the transport direction.
  • Rock wool insulation elements have binder contents of about 2 to about 4.5% by weight. With this small amount of binders, only part of the mineral fibers are in contact with the binder.
  • the binders used are predominantly mixtures of phenol, formaldehyde and / or urea resins. Some of these resins are already substituted by polysaccharides.
  • Inorganic binders are used as for the insulation elements made of glass wool only for special applications of insulating elements, as these are much brittle than the largely elastic to plastic plastic reacting organic binder, which accommodates the desired character of the insulating elements made of mineral fibers as elastic-resilient building materials.
  • the additives used are mostly high-boiling mineral oils in proportions of 0.2% by mass, in exceptional cases also about 0.4% by mass.
  • the primary nonwovens are deposited by means of a pendulum-suspended conveyor across another device for promotion, which allows the production of an existing from a variety of obliquely superimposed individual layers endless insulating material web.
  • the insulating material web can be folded more or less intense. From this insulating material webs, namely both the insulating material webs of glass wool, as well as the insulating material webs of rock wool strip-shaped sections are produced, which are referred to as lamellae and are used for example for lamellar plates and lamellar webs.
  • Slats are usually 5 mm to 500 mm wide insulation elements, which are separated in the conveying direction or transversely to the conveying direction of the insulating material web.
  • the mineral fibers in the slats are aligned at right angles to cut surfaces, which form the large surfaces of the slats, which are applied to large surfaces usually when using such slats in the thermal and / or acoustic insulation of building exterior surfaces at least on the building exterior.
  • Slats can have gross densities of about 60 kg / m 3 and are therefore suitable as tensile and pressure resistant insulating elements on building exterior surfaces and can be glued to these building exterior surfaces and then plastered with a proven plaster layer. Such insulation is referred to as a thermal insulation composite system.
  • the pressure-resistant lamellae are sufficiently flexible in the longitudinal direction in order to be able to be glued on curved building exterior surfaces.
  • the slats are still so compressible at right angles to the side surfaces that deviations from the respective length and width (dimensional tolerances) between the individual slats can be compensated with a small contact pressure. This can be used to produce joint-tight insulation layers.
  • Several lamellae can also be assembled into lamella plates or lamellar sheets, wherein the lamellae are either glued together or connected to one another via a lamination.
  • insulating elements in the form of slats takes place in different ways. All methods have in common that the lamellae are separated by disc from an insulating material web produced in the usual way. This production of lamellae is technically complex and generally leads to a lower throughput speed of the production equipment used for the production of insulating elements.
  • An economical method for the production of insulating elements with the characteristic of lamellae, lamellar plates or lamellar orbits orientation of mineral fibers is described in EP 0 741 827 B1. In this method, a thin primary nonwoven is unfolded by an up and down moving conveyor and placed endlessly and looped on a second conveyor. This creates individual layers that are pressed together in a horizontal direction and compressed.
  • the primary fleece is guided between two pressure-resistant bands, which initially limit only the height of the primary fleece.
  • the mineral fibers in the arcuately deflected paths of the primary web parallel to Aligned boundary surfaces.
  • the primary nonwoven can be actively compressed in the vertical direction.
  • This alignment of the mineral fibers in the primary nonwoven can be done in a separate device, but is advantageously made in conjunction with a curing oven in which the endless insulation web between two pressure belts, of which at least one is movable in the vertical direction, is flowed through with hot air in the vertical direction.
  • the pressure belts have pressure-resistant elements with holes in which surface regions of the insulating material web press in, whereby the surfaces are profiled. In the two surfaces of the insulation web may lead to a further alignment of the mineral fibers, a further compression compared to the underlying areas and possibly to a slight binder enrichment.
  • An insulating material web produced in this way can subsequently be divided into strip-shaped sections in the conveying direction or transversely thereto.
  • the quality of the manufactured elements in this process depends heavily on the cutting elements used.
  • dusty surfaces in the area of the elements for example, reduce the adhesion of such elements in a Klebemörtelbett.
  • elements which have shapes which deviate from the ideal shape of a body which is cuboid in cross section by means of cutting tolerances are formed. During the process, the individual elements are compressed, so that this also affects the advantageous embodiment of an element and thus can not be fully utilized.
  • These elements or slats are used as lamellar plates or lamellar sheets, for example in sandwich panels, which have a core of lamellae.
  • tolerances in thickness, angularity and moreover dusty surfaces lead to adhesion problems, to a reduction in the load-bearing capacity of the sandwich panel and to irregular surfaces of the sandwich panel, so that they can not be used in the desired manner.
