    Abstract: Heat-insulating compositions are made by mixing porous plastic particles with an inorganic binder consisting of a suspension of water-containing particles of alkali metal silicate and inorganic fillers in an aqueous solution of an alkali metal silicate, and solidifying at a temperature above >0 DEG C. but below that at which the plastic sinters. Solidification can be assisted by extracting water down to a content of 20%, by treatment with carbon dioxide, or by the application of pressure. The porous plastic may be polyurethane, polystyrene, copolymers of styrene and acrylonitrile, acrylic acid, or butadiene, vinyl chloride, or copolymers of vinyl chloride and vinylidene chloride. Flame retardants such as inorganic halogen compounds or mixtures of chloroparaffins and antimony trioxide may be included. The alkali metal silicate powder is preferably sodium silicate containing 16-20% water and having an Na2O/SiO2 ratio of 1:2.0 to 1:4.0. The solution is of 15-60 DEG Be1 concentration, and the total water content varies between 25 and 75% of the weight of the silicate. Magnesia, talc, calcium carbonate, powdered asbestos, glass, quartz, zinc carbonate, sodium silicofluoride, or silica gel can be used as fillers in the ratio of 1:1 to 4:1 relative to the anhydrous silicate.

    Abstract: Apparatus for producing fireproof sheets (see Group VIII) comprises a moving belt 1 having a rubber surface which may be plane, corrugated or profiled and on which belt a fabric web 4 is embedded in an aqueous alkali metal silicate solution, e.g. sodium or potassium waterglass, supplied through jets 4, 5. The silicate solution may contain a wetting agent, e.g. alkali metal salts of sulphonic acids or the sodium compound of the disulphonimide of a heavy gasoline, or colouring material. The embedded web 4 is dried at 7 by infra-red or electrically heated radiators with or without hot air blown counter current to the movement of the belt 1 and is cut to size by means 8.

    Abstract: Fireproof screens of the "venetian blind" type comprise a plurality of slats composed of an alkali metal silicate containing water and fibres, the slats being joined to each other by thermally stable connecting means and being adapted in the event of fire to move from an inoperative position in which the slats are substantially one behind another into an operative position in which they are spread out so that they only partly overlap one another. They may be held in the inoperative position by a cord of readily fusible material, e.g. a plastic cord, or by a fusible catch. The slats may be provided with mechanically, stable reinforcement, e.g. of wood or metal, and may be provided with a covering to protect them from atmospheric moisture and CO2, e.g. a covering of paper lined with aluminium foil. The specified slat material is an alkali metal silicate having a molar ratio of alkali metal oxide to SiO2 of 1:2 to 1:4 (preferably 1:25 to 1:3. 5) and containing from 20 to 70% (more preferably 40 to 60%) by weight of water and 10-40% (preferably 15 to 25%) by weight of synthetic silicate fibres.
