  • a flexible elastic carrier leads to a good drapability of the fire protection element, so that it can be arranged, for example wrinkle-free along curved surfaces.
  • the carrier is limp.
  • the extensibility of the fire protection element is so small that a Force of 100N with a fire protection element of one meter width and three meters high leads to a relative elongation of less than five millimeters.
  • the carrier is designed so that a thousand times winding on a winding shaft with a diameter of 10 cm results in that solve at most five percent of the cooling material from the carrier.

  • the binder decomposition temperature is understood to mean the lowest temperature for which, after one hour at this temperature, a mass loss of at least 15 percent by mass has occurred.
  • the binder decomposition temperature is sufficiently close to the activation temperature, the binder will degrade on the surface of the layer of cooling material when the cooling material reacts endothermically, releasing water vapor, for example.
  • the water vapor mixes with the decomposition gases.
  • the ignition temperature of this mixture is significantly higher than the ignition temperature of the decomposition gases alone. The mixture can therefore leave the fire protection element without igniting the decomposition gases.
  • the earlier onset decomposition of the binder therefore leads contrary to the intuition to a lower risk of fire and thus a lower fire load of the organic binder.
  • the binder decomposition temperature is greater than the activation temperature. It comes only to the decomposition of the binder when the cooling effect of the cooling material is already largely exhausted. It should be noted that the cooling material and the binder are applied in the form of a flexible layer on the flexible support, which layer preferably has a thickness of at least 0.2 mm, in particular at least 1 mm.
  • the layer of the cooling material facing the heat source When exposed to heat from the outside, the layer of the cooling material facing the heat source initially reacts to absorb heat. If the cooling material has lost its cooling effect, the temperature in the layer rises and the binder decomposes. So it forms a temperature gradient in the Layer of cooling material, which ensures that their mechanical stability is maintained and at the same time resulting decomposition gases are mixed with non-combustible gases, which arise during the endothermic reaction of the cooling medium.
  • the binder forms a matrix for the cooling material.

Such high coolant deposits can be achieved with the methods of the prior art only by using a variety of carriers.
  • the fire protection element has a heat absorption of at least 2000 kJ / m 2 . This high heat absorption makes it possible to withstand a fire for a long time. It is also advantageous that a fire or smoke protection curtain with such a fire protection element does not require intumescent material.
  • the fire protection element preferably comprises a first flexible insulating element, in particular a first insulating layer whose heat transfer coefficient is at most 8 watts per square meter, and a second flexible insulating element, in particular a second insulating layer whose heat transfer coefficient is at most 8 watts per square, the cooling material being arranged between the cooling elements is.

According to the relevant standard, however, only a maximum temperature of 160 ° C is admissible. The second insulation layer causes this temperature is not exceeded.
  • the insulating layer is understood to be an insulating element which is connected directly to the carrier. It is particularly favorable if the insulating element has a mineral wool, for example glass wool or rock wool. Alternatively or additionally, the insulating element may comprise ceramic phases.
  • the first flexible insulation element comprises a mineral fiber mat.
  • the second flexible insulating element comprises a mineral fiber mat.
  • the insulating member can be made thin. It is favorable if the thickness of the insulating element is at least 6 cm, clearly larger thicknesses are possible and encompassed by teachings according to the invention, but may be disadvantageous, since they lead to a thick fire protection element, which is undesirable.

  • the second textile element has such a coating.
  • the calorific value of the fire protection element is at most zero joules per square meter.
  • the oxidation of all components of the fire protection element with atmospheric oxygen leads to a release of heat, which is overcompensated by the heat absorption of the cooling material. That's the way it is possible and represents a preferred embodiment that at no temperature and at no time a possible oxidation of components of the fire protection element with atmospheric oxygen causes more heat is released by the oxidation than is absorbed by the cooling material.
  • the feature that at no time fulfills the stated requirement is understood in particular to mean that it is possible to average over a three-minute interval.

  • This can be achieved, for example, by virtue of the fact that at least one fire protection element turns its cooling layer to the other fire protection element and averts its metal foil layer. Since the metal foil layer is substantially gas impermeable, gas resulting from the endothermic reaction of the cooling material leaves the fire protection element in a direction away from the metal foil layer. It forms a gas cushion between the two fire protection elements, which presses apart. This gas cushion leads to a thermal insulation and thus increases the thermal resistance of the fire or smoke protection curtain.
