Definitions

  • the invention relates to a thermal insulation composite system with a fire barrier and the other features of the preamble of claim 1. Furthermore, the invention relates to a usable as a fire barrier in a thermal insulation system heat insulation element and the use of such a thermal insulation element as a fire barrier.
  • Thermal insulation systems of the type mentioned above include a one or more layers of several thermal insulation panels formed thermal barrier, often heat insulation panels are used, which consist of a hard foam, in particular of a polystyrene foam, or at least include such a thermal insulation material. Because appropriate thermal insulation materials have good thermal insulation properties and are relatively inexpensive. However, the fire behavior of such thermal insulation materials proves to be disadvantageous, which according to DIN 4102-1 are regularly attributable to building material class B (combustible building materials). If polystyrene rigid foam panels are flame-retardant, they are assigned to building material class B1 (flame retardant). The attached to the outside of a building exterior wall thermal barrier layer can therefore lead to an increase in fire load.
  • fire bars are used regularly above an opening of a building exterior wall.
  • the fire bars can be arranged above each opening or floor by floor as a circulating belt.
  • a façade full thermal insulation composite system which includes an effective as a fire barrier, insulation board made of polystyrene foam.
  • the insulation board made of polystyrene foam has for this purpose a full thickness of the insulation board formed, embedded or attached strips of a non-melting in the heat, preferably non-flammable or flame-retardant insulation.
  • This insulating material may be, for example, a mineral fiber or glass fiber insulating material. If a single- or multi-layered plaster layer is subsequently applied, the use of such insulating materials within an insulating layer consisting of polystyrene rigid foam can lead to undesired color deviations or markings on the facade.
  • Utility Model DE 20 207 007 225 U1 a component for a thermal insulation composite system proposed which comprises two insulating elements and an intermediate, substantially over the entire cross-sectional area of the component extending fire protection layer.
  • the fire protection layer is preferably made of mineral wool, glass cloth, needle felt, a coated glass net and / or mortar.
  • the present invention seeks to provide a simplified thermal insulation composite system with a fire barrier.
  • a fire barrier to find a flexible and easy to use as possible thermal insulation element use.
  • the thermal insulation element should allow the formation of a fire barrier in a fall and / or reveal area of an opening in a building exterior wall.
  • the proposed composite thermal insulation system has a mounted on an outer side of a building exterior wall single or multi-layer thermal barrier coating and a single or multi-layered plaster layer applied thereto, wherein the thermal barrier coating at least one thermal insulation panel of a rigid foam, in particular of a polystyrene foam, and at least one plate or profile-shaped thermal insulation element for forming a fire barrier comprises.
  • the fire barrier forming, plate or profile-shaped thermal insulation element comprises a thermal insulation material, which airgel particles and at least one water-based organic and / or inorganic binder and has a thermal conductivity ⁇ 0.028 W / (mK), preferably ⁇ 0.025 W / (mK), further preferably ⁇ 0.022 W / (mK).
  • Airgel-based thermal insulation materials have a very low thermal conductivity and thus excellent thermal insulation properties. As a result, the insulation thicknesses can be significantly reduced while fulfilling the requirements with regard to thermal protection.
  • the addition of at least one water-based organic and / or inorganic binder causes a stable composite of the airgel particles with each other, so that further the mechanical properties and thus the construction site suitability of the thermal insulation material containing thermal insulation element can be improved.
  • a heat insulating element made of such a thermal insulation material may be formed as a thin plate, which is particularly suitable for thermal insulation of a lintel or soffit surface of an opening in the building exterior wall. As a rule, in the fall or reveal area of an opening, such as a window or a door, no large insulation thicknesses can be performed.
  • the excellent thermal insulation properties of the thermal insulation material or of the thermal insulation element produced therefrom have a particularly advantageous effect.
  • the specified thermal insulation element of the thermal insulation composite system according to the invention fulfills the function of a fire barrier, which in case of fire can prevent or at least significantly delay a fire expansion to an adjacent thermal insulation layer from a heat insulation material which is combustible according to DIN 4102-1.
  • aerogels are also classified as flammable on their own, whereby the classification into the building material class B1 (flame retardant) takes place.
  • the binder contained in the thermal insulation element in particular in the case of a water-based organic binder, may be assigned to the building material class B2 (normally flammable), so that the thermal insulation element may only reach the building material class B2.
  • thermal insulation element as a fire barrier could be demonstrated in the context of attempts by the applicant - which will be described below with reference to concrete examples. It is due to the low thermal conductivity of the thermal insulation material of the thermal insulation element, which in the present case ⁇ 0.028 W / (mK), preferably ⁇ 0.025 W / (mK), further preferably ⁇ 0.022 W / (mK).
  • the fire barrier forming, plate or profile-shaped thermal insulation element in the region of an opening of the building exterior wall, in particular above and / or arranged laterally of the opening.
  • fires occur in closed rooms and are transmitted to the façade via openings in the external wall of the building, in particular windows and doors. Due to the proposed arrangement of the plate or profile-shaped thermal insulation element, such a fire flashover can be effectively prevented or at least significantly delayed.
  • the reduced insulation thickness of the thermal insulation material of the plate-shaped or profile-shaped thermal insulation element comes into play.
  • the plate or profile-shaped thermal insulation element of a thermal insulation composite system according to the invention preferably has a thickness of 10 to 30 mm, which is sufficient to form a fire barrier. If the thermal insulation element is formed in a profile shape, it may for example be L-shaped and embrace the soffit or the lintel.
  • the fire barrier forming, plate or profile-shaped thermal insulation element of a thermal insulation composite system according to the invention has a flush with the outside of the single or multi-layer thermal barrier coating final upper or side surface.
  • the flush with the thermal barrier coating final upper or side surface of the thermal insulation element serves to accommodate the one or more layers of plaster, so that they can be formed without interruption and also in uniform thickness.
  • the plaster layer can also be performed uninterrupted and in uniform thickness around the soffit or the fall around to the window or door system.
  • the flush with the thermal barrier coating final upper or side surface of the thermal insulation element further ensures that the space between the outside of the building exterior wall and the single or multi-layer plaster layer is completely filled by the thermal insulation element. There remains no cavity, which could favor fire expansion. In this way it is further prevented that already molten thermal insulation material drips above a firing bar and ignites or at least damages the hot melt underlying material. The dripping melt could also persons hurt. Thus, a particularly effective protection is achieved by the fire barrier.
  • the plate-like or profile-shaped thermal insulation element which is also proposed for solving the above-mentioned object can be used as a fire barrier in a thermal insulation composite system according to the invention and comprises a thermal insulation material which contains airgel particles and at least one water-based organic and / or inorganic binder and has a thermal conductivity ⁇ 0.028 W / (mK), preferably ⁇ 0.025 W / (mK), further preferably ⁇ 0.022 W / (mK).
  • the low thermal conductivity is due to the contained airgel particles.
  • the present thermal insulation of a thermal insulation element according to the invention also due to the binder further contained good mechanical properties, in particular sufficient stability, so that even low insulation thicknesses can be realized.
  • the low thermal conductivity of the thermal insulation material is one reason that the thermal insulation element also fulfills the function of a fire barrier. Because of the plate-shaped or profile-shaped thermal insulation element, the adjacent thermal barrier coating of the thermal insulation composite system is essentially protected from the heat generated during firing. In this way, in particular a melting of the adjacent thermal barrier coating is prevented. Accordingly, the plate or profile-shaped thermal insulation element could also be referred to as a heat protection element.

  • a higher binder content not only has an unfavorable effect on the thermal insulation properties of the plate-shaped or profile-shaped thermal insulation element. He also has the disadvantage that there is a risk that the binder decomposes in the event of fire under the action of heat and burned or evaporated. The resulting decomposition gas has a high explosive force and can lead to complete destruction of the thermal insulation element. In this respect, the specified maximum values should not be exceeded and the further specified minimum value for achieving a sufficient mechanical strength should not be undershot.
  • the Designing gusset volume is understood here to mean the entire volume of air and / or binder filled gusset volume between the airgel particles.
  • the thermal insulation material has preferably been compacted during production in a mold or on a belt system with the addition of pressure and / or heat.
  • the water content of the water-based organic and / or inorganic binder contained in the thermal insulation material of the thermal insulation element is at least 50% by weight, based on the total weight of the binder.
  • the high water content increases the wettability, so that a uniform distribution of the binder and, consequently, a stable composite of the airgel particles can be achieved with one another even at the low binder content described above.
  • the water-based organic binder is a water-based thermosetting binder such as epoxy resin or polyurethane, and / or a dispersion binder based on thermoplastic vinyl acetate, acrylate, styrene acrylate or styrene butyl acrylate polymers or other polymer dispersion.

  • a water-based inorganic binder may also be present, this being preferably soda or potassium silicate glass.
  • At least part of the contained airgel particles consists of airgel recyclate. In this way, costs can be saved because the airgel particles are expensive to manufacture and thus expensive. It also contributes to environmental protection by producing less waste.
  • the plate or profile-shaped thermal insulation element according to the invention is produced continuously from the airgel particles and at least one water-based organic and / or inorganic binder containing thermal insulation material. It thus preferably has a homogeneous structure.
