Definitions

  • the invention relates to a method for producing fire protection insulation, in which a core storage mass, which changes its structure endothermically before reaching a permissible maximum temperature, is embedded in an open-pore support structure made of mineral fibers.
  • Fire protection insulation is understood to mean devices that limit the heat transfer in steel fire 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-proof 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 inner insulating layer made of urethane foam and an inner inner wall made of sodium acetate trihydrate.
  • the sodium acetate trihydrate used for the innermost wall is a substance called core storage mass and its structure is endothermic when exposed to heat. H. changes under heat absorption.
  • the temperature in the interior of the cabinet or generally on the side of a wall which has been switched off in such a way 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 cabinet contents in that a purely inorganic, non-flammable salt with high crystal water content, such as sodium metasilicate hydrate, is used as the core storage mass with 5, preferably 9 H 2 0 is used.
  • a purely inorganic, non-flammable salt with high crystal water content such as sodium metasilicate hydrate
  • the use of 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.
  • Glauber's salt i. H. 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 object of the invention is to propose a method for producing fire protection insulation, by means of which the fire protection insulation can be designed in such a way that the risk of a sinking of the core storage mass which melts under the continuous application of heat can be eliminated even more reliably, so that the time until which the heat insulation remains fully effective, is further increased.
  • Fig. 1 1 means the outer jacket of a fire-safe cabinet with thermal insulation according to the invention
  • the z. B. consists of sheet steel.
  • 2, 3, 4 and 5 are mineral fiber boards.
  • 6 and 7 are housing walls, between which the core storage mass 8 is provided, which is embedded in a supporting structure 9 which, in the exemplary embodiment shown, consists of mineral wool torn into flakes.
  • Fig. 2 is indicated at 11 and 12 each with a phenolic resin bound mineral fiber plate of about 2 cm thick. 13 means a 1.5 cm thick layer of core storage mass supported by mineral wool (mixing ratio 1: 4), onto which an aluminum foil 16 or 17 is bonded as a vapor barrier with a thickness of 200 ⁇ by means of a water glass adhesive layer 14 or 15.
  • a commercially available fire protection coating composition based on water glass is preferably used as the adhesive, which expands at a higher temperature with the formation of foam and swallows heat through evaporation at approximately 100 ° C. and thus additionally contributes to thermal insulation.
  • FIG. 3 shows a longitudinal section, shortened by the dash-dotted lines, through a fire protection door with fire protection insulation according to FIG. 2.
  • the fire protection door 21 sits in the door opening of the masonry of a fire-protected room 22 with a floor 23 with a lower stop 24 and a ceiling 25 with an upper stop 26.
  • the framework of the fire protection door 21 is partially recognizable at 27 at the top and 28 at the bottom.
  • a door closer not forming part of the invention is shown schematically and partially.
