  • Aging-resistant fireproofing material
    Patent number: 4297252
    Abstract: A fireproofing material based on alkali metal silicates and containing from 20 to 60 percent by weight of water, which additionally contains from 1 to 10 percent by weight of a borate or an aluminate, preferably sodium aluminate, to improve the aging resistance. The fireproofing material can be used to insulate apertures and passages in building structures against the passage of fire and smoke, and can also be used as a fireproof glass.

  • Manufacture of fire protection materials based on alkali metal silicates
    Patent number: 4172110
    Abstract: A process for the manufacture of fire protection materials, in which an aqueous alkali metal silicate solution is dried to a water content of from 6 to 40% and the resulting powder is thermoplastically molded to form sheets, tapes or strips. These can be fitted into openings and passages of building units; in the event of a fire they eliminate water and form a stable, heat-insulating foam.
