  • a chamber is formed from two discs and sealants along the edge region of the discs, which with a fire protection compound filled and closed, whereupon the fire protection compound is cured to the fire protection layer. It is also known to apply a fire protection compound on a first support member (a first disc), there to dry until they hard, and then attach the second support element on the resulting fire protection layer.
  • the material of the fire protection layer is usually an alkali metal polysilicate with, for example, the highest possible water content.
  • Water-containing, organic, gel-like "polymer hydrogels" are also known as the material for fire protection layers.
  • the fire protection layers have in common that they are transparent at room temperature but cloudy and foam under the action of heat.A visible opaquing can be achieved even at relatively low temperatures, eg. between 60 and 70 ° C.
  • a method according to the invention for joining a prefabricated fire-resistant glass as the first component, consisting of at least one water-containing fire protection compound filled, closed chamber of two spaced glass panes and all-round seal, with at least one further glass pane as a second component, is characterized essentially by the fact that on a broadside (ie a flat side) of one of the two components, a hot melt adhesive film is applied, the other component is brought to the hot melt adhesive sheet and the components in the resulting composite under pressure and temperature are joined together to form a transparent composite body.
  • the fire protection compound (or fire protection layer) is a composition which foams under the action of heat, advantageously a polysilicate, for example of the type known from EP 0 620 781.

Aggregated in the silicate matrix - water, bubbles and forms thereby the foaming (co-) caused.
  • the invention uses the approach that in the chamber with the hydrous fire protection layer when heated, the bubbles and even more a stronger vapor formation must be prevented until foaming. Because once a turbidity is irreversible.
  • the haze can be prevented by foaming at higher temperatures when the fire glass is kept under pressure. It is known from physics that the boiling point of a liquid is dependent on the prevailing ambient pressure. The higher the ambient pressure, the higher the boiling point. Likewise, the solubility of gases in liquids is usually higher when the pressure rises. Bubble formation in the heat-insulating and / or cooling material can therefore be deliberately suppressed by an applied higher ambient pressure.
  • the invention is based on the fact that the aggregation of the water to the substrate is also pressure-dependent, that is to say that the de-aggregation of the water is delayed at elevated pressure.
  • Typical transparent hot melt adhesive films or composite films for bonding glass panes are, for example, PVB (polyvinyl butyral), EVA (ethylene vinyl acetate), THV (fluoropolymers), PU (thermoplastic polyurethanes). These films have a softening start at temperatures of 75-140 ° C. Fluoropolymers must be pressed at even higher temperatures of 150-180 ° C. These are all temperatures at which the polysilicate laminated glass clouds and would foam up when they are glued by means of a film with the safety glass composite. The composite body produced would then no longer be completely transparent and thus ultimately useless.

  • This fire protection layer is incompressible, it behaves under pressure almost like a solid, which means that a pressure from the outside on the glass panes propagates inwards, so that the matrix with the stored or aggregated water is under pressure and thus the water.
  • this pressure must be practically arbitrarily high, at least so high that at the required bonding temperature of the desired film no bubble formation begins, in other words, the silicate matrix does not cloud and foams.

  • the course is driven so that the pressure is always so high that the boiling point of water or the respective boiling point of the hydrous fire protection layer when applied is always below the applied temperature.
  • the determination of the respective boiling point of the fire protection layer is - if the boiling point can not be looked up - experimentally by observing the onset of blistering easily possible and easily reproducible for a particular fire protection layer composition. In some fire-retardant compositions, blistering may begin even before the water-boiling point is reached.
