Definitions

  • the utility model is in the field of construction products and refers to the construction of the composite insulation panel.
  • panel [1] representing an insulating decorative plate which is composed of a layer of polyurethane foam and fiber concrete layer on one side of the layer of polyurethane foam.
  • the other side of the fiber concrete layer has edges connecting layer which is a layer of cement glue or a line of polyurethane adhesive.
  • the object is to create a panel in which production wet processes lack whereas there is no drying or evaporation.
  • a composite panel consisting of a layer of insulating material having a closed cell structure and a layer of non-flammable fabric.
  • the insulating layer is a polyurethane foam or polyisocyanurate foam, or EPS, or XPS- with a thickness of more than 20 mm.
  • the second layer is a fiberglass cloth with a thickness of not more than 2 mm.
  • the two layers are glued to one another.
  • Fiberglass cloth extends beyond the dimensions of polyurethane foam with no more than 40 mm. in the two neighboring sides 2
  • a decorative polymer coating is used with a thickness of less than 3 mm.
  • the above-described panel is intended for external and internal uses.
  • the utility model has advantages for easy construction, combination of thermal insulation and decorative effects, perfect thermal insulating effect, non-toxic, fire-proved and has a wide applicability.
  • the utility model has the capability to adapt to large-scale and continuous industrial production and has a stable quality.
  • Figure N° 1 shows the composite panel of polyurethane foam and fiberglass cloth.
  • N° Figure 2 shows a composite panel of polyisocyanurate foam and fiberglass cloth.
  • Figure N° 3 shows the composite panel of polyisocyanurate foam and decorative polymer coating.
  • Figure N° 4 shows a composite panel of polyurethane foam and decorative polymeric coating.
  • the composite panel comprises a layer of insulating material having a closed cell structure and a layer of nonflammable fabric.
  • the insulating layer is a polyurethane foam 1 with a thickness of more than 20 mm.
  • the second layer is a fiberglass cloth 2 with a thickness of less than 2 mm.
  • the two layers are glued to one another.
  • glab 6 and 7 is made to both neighboring sides and a tooth respectively 5 and 8 to the opposite of these sides, which eliminates any thermal bridge during installation.
  • the fiberglass fabric 2 extends beyond the dimensions of the polyurethane foam 1 with not more than 40 mm. in the two neighboring sides.
  • the insulation material with a closed cell structure is polyisocyanurate foam 4.
  • the other layer is a fiberglass cloth 2 with a thickness of not more than 2 mm.
  • FIG. 3 Another embodiment of the utility model is shown in Figure 3.
  • This panel consists of an insulating material with closed cell structure of polyisocyanurate foam 4 and finishing decorative polymer coating 3 with a thickness less than 3 mm.
  • Technological equipment necessary for the use of composite panels is as follows: knife; silicone cups 100ml.; mixers; dosing system; leveling system and plumbing; scaffolding platform; foam gun; airless spray glue machine; wallpaper cutting table; airless facade paint spray machine.
  • Necessary raw materials for the installation of composite panels polyurethane foam system - retainer; one-component polyurethane foam adhesive; polyurethane or epoxy glue; wallpaper for exterior use and a cleaner.
  • the preparation for the installation of composite panels on a facade of a building includes: standing of a scaffold around the building or mounting a platform; making measurements of the facade and making an action plan.
  • the polluted areas are washed and dried. Prior to washing with water, the fatty stains are treated with 2% hydrochloric acid solution.
  • Salt cleaned areas are washed and dried to a moisture content of not more than 8%.
  • the base especially for metal surfaces must be dry and free of oil, as the integrity and load capacity of the base (especially for application on walls) is revised.
  • the bottle of glue is shaken for about 30 seconds, turned upside down and screwed to the gun for polyurethane foam.
  • Vial is held in an upright position during application.
  • Composite panels must be applied within a maximum of 10 minutes after the adhesive is applied.
  • Curing time of the adhesive depends on the temperature and humidity.
  • the curing time of the adhesive can be reduced by spraying water onto the strips of polyurethane adhesive.
  • the side which is to be closed is covered with a polyurethane adhesive prior to installation.

Abstract

La présente invention se rapporte au domaine des produits de construction et concerne la construction d'un panneau d'isolation composite. Le panneau composite comprend une unique couche de mousse de polyuréthane (1) ayant une épaisseur de plus de 20 mm. La seconde couche est une toile de fibre de verre (2) ayant une épaisseur inférieure ou égale à 2 mm. Les deux couches sont collées l'une sur l'autre. Sur la périphérie du panneau, un évidement (6 et 7) sur les deux côtés voisins et une dent respectivement (5 et 8) à l'opposé de ces côtés sont amenés à éliminer tout pont thermique pendant l'installation. Dans ce cas, la toile de fibre de verre (2) s'étend au-delà des dimensions de la mousse de polyuréthane (1) ne dépassant pas 40 mm dans les deux côtés voisins.
