Definitions

  • the invention relates to fire protection insulation.
  • Fire protection insulation is to be understood as equipment that limits the heat transfer in steel fire protection doors. Until now, such fire protection insulation consisted only of inserts made of mineral fiber boards. The term, designation, requirements and tests are set out in DIN 18 089, draft from February 1981.
  • fire-safe cabinets for storing temperature and moisture sensitive objects, such as magnetic tapes, films, index cards or the like.
  • a fire-safe cabinet has become known, the walls of which consist of an outer thick concrete layer, an insulating layer made of urethane foam and an inner wall of sodium acetate trihydrate.
  • the sodium acetate trihydrate used for the innermost wall is a substance that is referred to as core storage mass and, when exposed to heat, its structure endothermic, i. H. changes under heat absorption.
  • core storage mass a substance that is referred to as core storage mass and, when exposed to heat, its structure endothermic, i. H. changes under heat absorption.
  • the temperature in the interior of the cabinet or generally on the side of a wall designed in this way, which is turned away from the location of the fire is limited in time to a certain height.
  • urethane foam is flammable and the sodium acetate trihydrate used as the core storage mass develops flammable gases when exposed to heat through chemical decomposition.
  • a fire-safe cabinet has become known, in which a better efficiency is achieved with regard to securing the contents of the cabinet by using a purely inorganic, non-combustible salt with a high crystal water content, such as sodium metasilicate hydrate, as the core storage mass with 5, preferably 9 H 2 O is used.
  • a purely inorganic, non-combustible salt with a high crystal water content such as sodium metasilicate hydrate
  • sodium metasilicate hydrate not only avoids the development of flammable gases when exposed to heat, but because of its proportionately higher water content also provides a significantly higher thermal capacity of the core storage mass than the acetate compound.
  • Another purely inorganic, non-flammable salt that can be used equally as a core storage mass with high heat capacity is, for example, Glauber's salt, ie sodium sulfate decahydrate.
  • the heat exposure continues, then it melts at a certain temperature while absorbing heat in its own crystal water, e.g. B. sodium metasilicate hydrate at about 48 ° C.
  • the melt sinks down and there are free spaces in the upper areas of the fire protection walls, doors or similar locking devices, i.e. there are free spaces for heat transfer and heat transfer.
  • the object of the invention is to accommodate the core storage mass in the space intended for it in such a way that the risk of the core storage mass melting under continuous exposure to heat being eliminated is largely eliminated and therefore no free spaces dangerous for heat transfer or passage can occur in corresponding areas of the fire protection insulation . Furthermore, the thickness dimension of fire protection doors in particular should be reduced compared to a conventional mineral fiber panel.
  • the core storage mass is embedded in an open-pore support structure made of a material with good wettability compared to the core storage mass in the molten state.
  • the supporting structure prevents an immediate and unimpeded drainage of the core storage mass, which has become liquid due to the application of heat, following gravity.
  • the support structure can consist, for example, of preferably granulated mineral wool.
  • a bed of an absorbent filler optionally in admixture with mineral wool, flour as in ⁇ play-grained to powdered diatomaceous earth, pumice stone or granular, ground perlite, may be used as scaffold
  • the core storage mass is advantageously distributed differently in the support structure in accordance with the temperature profile to be expected under the influence of heat, so that where the highest temperatures are to be expected, the highest
  • Concentration of core storage mass is present in the scaffolding.
  • bulkhead-like internals can be provided in a room to be set with the fire protection insulation according to the invention, which have the effect that these cannot sink as a whole, particularly when subjected to strong impacts. Such impacts can occur in the event of fire when building parts collapse and therefore z. B. fireproof cabinets also checked accordingly.
  • the core storage mass supported by a supporting structure can be used as such, but also as a shaped body or plate.
  • the structure of the support structure and core storage mass is expediently covered on all sides with a vapor barrier, which can consist of a metal, plastic or a combined metal-plastic film.
  • a vapor barrier also means that the walls of cupboards or doors, which are generally made of steel, cannot be damaged because undesirable chemical interactions between the wall and the core storage mass used are excluded.
  • a metal foil as a vapor barrier
  • It can be a water-glass-based coating composition known per se.
  • Such a coating composition has the further advantage that it is foamed at a higher temperature formation inflates and thereby increases the insulating effect and the evaporation heat Ver ⁇ swallows.
  • Stainless steel, copper or aluminum can be used as the material for the metal foil.
  • Stainless steel, copper or aluminum can be used as the material for the metal foil.
  • Stainless steel, copper or aluminum can be used as the material for the metal foil.
  • polyethylene, polytetrafluoroethylene or the like proven useful.
  • an organic adhesive for example an epoxy resin adhesive
  • an epoxy resin adhesive is expediently used as the adhesive.
  • normal water glass adhesives with a high solids content and higher consistency are more advantageous, or the use of a fire protection coating composition which foams is particularly expedient.
  • the core storage mass is influenced when using water glass adhesives, but only in extremely thin surface layers.
  • the fire protection insulation according to the invention is produced by mixing granular to powdery core storage mass with granulated mineral fiber wool, optionally with the addition or exchange of granular to powdery fillers, and introducing this mixture into the space to be filled with the core storage mass.
  • Another possibility is to impregnate a mineral fiber board, optionally filled with fillers, by soaking it with molten core storage mass and then allowing it to cool. It has proven to be particularly advantageous to tear mineral wool into flakes, the flakes, if necessary, after adding fillers with a molten core Mix storage mass and compress the resulting mixture into moldings which are allowed to solidify while cooling.
  • the flakes can also be mixed with granular to pulverulent core storage mass with the addition of heat and the pulpy mixture formed can be pressed into shaped bodies which are allowed to solidify while cooling.
  • Another possibility is to mix the flakes with granular to powdery core storage mass and an adhesive and to shape the resulting mixture into shaped bodies. Suitable adhesives are the adhesives already listed above with regard to their properties.
  • a salt with a high crystal water content is used as the core storage mass, it is advisable to use a largely, preferably completely water-free adhesive, for example an epoxy resin adhesive.
  • a particular advantage of the fire protection insulation according to the invention is given in particular in the case of fire protection doors in that the insulation layer thickness required in terms of fire protection can be markedly reduced in relation to the conventional mineral fiber insert.
  • the specified mineral wool or mineral fiber structures are those made of mineral fibers, preferably of a silicate nature.
  • a different degree of impregnation can also be achieved by impregnating a mineral fiber mat or plate of different density with the liquefied core storage mass from top to bottom.
  • the location at the top is chosen to be the lower mat density, so that more core storage material is absorbed there.
  • the scaffold surfaces have such a high affinity for molten core storage mass that they are able to hold the core storage mass like a liquid in a sponge. So it must always be ensured that the support framework material, in particular the mineral fibers, is kept free or freed of, for example, oily substances which would prevent such wetting.

  • the fire protection insulation consists of pure mineral fibers with a total thickness of 5 cm. It can be seen that with a constant rise in temperature after .ca. 50 minutes a temperature of over 100 ° C and after a total of 110 minutes a temperature of approx. 200 ° C is reached on the side facing away from the fire.
  • fire protection insulation of the same overall thickness as in Fig.
  • the temperature on the side facing away from the fire remains after reaching the specific temperature for the particular core storage mass used, for example 48 ° C or for example 85 ° C is at this temperature for about 50 minutes, as can be seen from FIG. 2, and only increases again after a total of 100 minutes of exposure to fire, until the value of 200 ° C., which does not use a core storage mass, is reached only after about 150 minutes under permanent

  • sodium sulfate decahydrate for example, a holding temperature at 32 ° C is given.
  • curve I for the upper area would result in a disproportionately rapid increase after the end of the holding temperature to the final temperature and beyond, because if the core storage mass became molten, the thermal insulation that was present even with the molten core storage mass would completely disappear.
