Definitions

  • This invention relates to special stable moldings or stable plates as a lightweight material for applications of all kinds and in particular when designed as plates for installation as internal and external thermal insulation of buildings.
  • the plates and moldings are also versatile for fire protection.
  • the invention relates to the process for the preparation of these stable moldings and plates, their use and finally structures consisting of or containing such moldings or plates, or structures in which external or internal walls are equipped therewith against the heat transfer, i. are "insulated” in the usual way of industry - that is, thermally insulated.
  • a plaster is best.
  • the lining of winding staircases, round arches and retaining walls with conventional thick insulation boards is sometimes costly.
  • a cladding made of insulating plaster can be decidedly easier to install, especially on winding areas.
  • the plaster rests directly on the masonry and leaves no gaps where moisture can condense. In practice, therefore, often resorting to combinations of insulation boards and insulation finishes. Large, flat surfaces are covered with insulation boards, however, angular areas of the building are provided with insulating plaster.
  • Airgel One of the best, if not the very best, insulating material that can be industrially produced is airgel.
  • the material also known as "frozen smoke” because of its appearance, consists of about 5 percent silicate - the rest is air.
  • Airgel was already used in the 1960s to insulate space suits and brought it to 15 entries in the Guinness Book of Records, including those as “best insulator” and “lightest solid", with thermal conductivities or Lambda values of 2 to 5 mW / (mK).
  • Airgel already used for example as an inflatable insulation material for wall gaps or in the form of insulation boards made of fiber fleece.
  • airgel pellets are extremely light, almost weightless and they can be held between thumb and forefinger.
  • this airgel insulating plaster would be more than twice as good thermal insulation as a conventional insulating plaster and comparable or even better insulating than a sheet of extruded polystyrene (EPS).
  • the conventional insulating plasters have thermal conductivities or lambda values between 65 and 90 mW / (mK), the worst only a ⁇ value of 1 10 or 130 mW / (mK).
  • the airgel insulating plaster is sprayed with a plastering machine on the masonry and then pulled smooth. This soft insulating plaster must then be protected in a further operation with a fabric-embossed investment mortar.
  • an airgel applied as a pumped plaster lets through significantly more heat, especially when the pumping section is long. Due to the mechanical stress of the airgel in the pump its effect coincides and the thermal conductivity or the lambda value increases. In the case of a 30-meter-long pumping line, the heat transfer and thus the thermal conductivity or the lambda value increase from 30 to 40 to 45 mW / mK.
  • Thermal insulation panels on the other hand suffer through their installation Deterioration of their ⁇ value.
  • An airgel plate has a ⁇ value of 15 to 20 mW / mK, which is better than an extruded polystyrene plate (EPS plate) with its ⁇ value of 33 mW / mK.
  • EPS plate extruded polystyrene plate
  • thermal insulation panels can not be used everywhere, they are ideal in many situations because they offer a low ⁇ value. Airgel panels or airgel insulation plasters are generally very expensive. If a thermal insulation panel with comparable ⁇ values could be used at much lower prices, it would be highly interesting for many applications.
  • a thin and lightweight insulation board can always be installed quickly and easily and it can be cut to any size.
  • fire protection is about a large heat - high temperatures - keep as long as possible due to a fire on one side of the fire protection board from the other side of the fire protection board.
  • the density of the plate plays a different role. It should be high, so that the plate due to their material and its mass in case of fire has an endothermic reaction, that is, can absorb large amounts of energy when exposed to heat due to the elimination of large amounts of water and other reaction products.
  • a cooling effect of the system is the result.
  • Conventionally used as base material for example, materials based on gypsum, calcium silicate, expanded mica, expanded clay.
  • the binding title is water glass, gypsum, phosphates and cement, in particular magnesium cement or glass cement.
  • a fire protection board should be as light as possible and as hard as necessary, with the best possible fire protection properties.

  • the perlites which have a low bulk density of less than 300 grams / liter as dry expanded product, are broken.
  • insulation boards with a low bulk density have a higher porosity and accordingly always a better insulating effect.
  • open-celled perlites which naturally have a high water absorption capacity and accordingly are less suitable as thermal insulation material, are produced in traditional ovens.
  • the insulating effect is increased when as much air is introduced into the plate. It has been found that the proportion of air in the insulating board can be increased by deliberately introducing a foaming agent when the mineral binder is mixed or mixed.

Abstract

L'invention concerne des corps moulés et des plaques utilisés en tant que matériaux légers pour équiper des enveloppes de bâtiment d'une isolation thermique ou comme moyen local de protection contre l'incendie. Ils sont produits à base de perlite expansée, à partir d'un mélange homogène qui durcit ensuite. Plus précisément, une plaque de ce type est composée d'un mélange homogène gâché contenant une composition d'au moins 40 % en volume de billes de sables de silice expansés vitrifiées, à cellules fermées en surface, remplies d'air, qui présentent une densité de seulement 50 à 400 grammes/litre, de sorte que du fait des perlites à cellules fermées, non fissurées, aucune mesure n'est normalement nécessaire pour une hydrophobisation. Le volume restant est composé d'un liant minéral ou organique qui a été gâché conjointement à l'addition d'un agent moussant, de sorte au la plaque présente au total, selon la composition spécifique de tous les composants en raison de l'air présent dans les perlites expansées et de l'air provenant de l'agent moussant, une densité comprise entre 120 kg/m3 et 1200 kg/m3. Dans un mode de réalisation sous forme de plaques isolantes, ces plaques sont utilisées pour fabriquer des structures de paroi intérieures ou extérieures de bâtiment, les plaques isolantes (8) étant appliquées sur une paroi intérieure ou extérieure de bâtiment nettoyée, égalisée par un enduit puis munie d'un ciment-colle. Elles peuvent au besoin être fixées mécaniquement à la paroi de bâtiment, après quoi peut être appliqué un sous-enduit (9) muni d'un treillis ou d'un tissu d'armature (10) à base de verre, puis un enduit de finition qui peut être sélectivement muni d'une peinture.
