  • the sodium water glass has a composition with an average molar Na 2 O / SiO 2 ratio of 1: (1.5 to 4.0) and if the sodium water glass is initially liquid in the insulating compound 7 is introduced, it should have a density of about 1.32 to 1.55 g / cm 3 .
  • the amount of water glass introduced into the insulating compound 7 should be selected such that the magnesium oxychloride cement or magnesium oxychloride-magnesium oxysulfate cement has a composition with an average molar ratio of MgCl 2 to soda water glass of approximately 1: (0.02 to 0.35) having.
  • the insulating compound 7 contains silica contains. This can e.g. can be added as an amorphous powder.
  • silica in the insulating compound 7 brings about similar improvements in properties like that of water glass, but it increases its effectiveness.
  • silica is a collective name for compounds that Silicon dioxide and different proportions of water can contain. So a distinction is made between orthosilicic acid, different types of polysilicic acids and Metasilicic acids and finally the so-called phyllodic silica, whereby the mentioned silicas by an increasing in the order given Characterize degree of condensation and decreasing water content and in the final stage the condensation occurring to form chain molecules is almost anhydrous Silicon dioxide is created.
  • Silicic acid can be precipitated by means of metal salt and / or acid from water glass are generated, with a low degree of condensation they are initially used as (liquid) Hydrosol is present and at an appropriate temperature (starting at Room temperature or a little above) and at an appropriate pH value (greater or less than about 3.1-3.3) an envelope of the colloidally disperse silica particles uses, which can lead to gel formation.
  • the silica is higher in a network and / or honeycomb structure specific surface and porosity arranged in the water.
  • the circumstance of the sol-gel reaction can be used according to the invention by the silica through Precipitation using metal salt and / or acid from the insulating compound 7 initially contained water glass is generated. This advantageously results on the one hand an increase in strength and fire resistance, and on the other hand, the Shrinkage amount of the curing insulating compound 7 is reduced.
  • the fire protection insulation 7 is - as stated - in the flowable state in the Hollow chamber H introduced.
  • a magnesium oxychloride cement a fire protection insulation 7 used, which from a Mixture of magnesium oxide (reactively fired magnesia) and concentrated, in particular saturated or supersaturated, aqueous magnesium chloride solution is produced and also produced with the addition of magnesium sulfate can be.
  • a metal chloride such as Calcium chloride, the cation of which forms poorly soluble sulfates, such as calcium sulfate.
  • the insulating compound 7 can also with the addition of water glass, in particular Sodium water glass in liquid solution, preferably two Partial mixtures, one of the starting materials mentioned for the magnesium oxychloride cement and another from the water glass, if necessary mixed with magnesium sulfate, to be stirred into a highly viscous suspension.
  • water glass in particular Sodium water glass in liquid solution, preferably two Partial mixtures, one of the starting materials mentioned for the magnesium oxychloride cement and another from the water glass, if necessary mixed with magnesium sulfate, to be stirred into a highly viscous suspension.
  • the insulating compound 7 can also contain silica, which is preferably produced in the manufacturing process of the insulating compound 7 by precipitation from water glass using acid or salt. Mineral and / or organic acids can be used to set a suitable pH.
  • a fire resistance class of up to F120 can be achieved.
  • the invention is limited not to the various illustrated embodiments, but also includes all equivalent designs.
  • the person skilled in the art can additional others provide advantageous measures, such as the admixture of fillers or pigments for fire protection insulation 7, in particular zinc oxide, Titanium oxide and aluminum oxide are particularly suitable.
  • an embedding reinforcing parts or materials, such as glass fibers or a fabric made of plastic, wire, glass fibers or the like, into the fire protection insulating compound 7 can be provided as a measure that reinforces the advantages of the invention.
