    Abstract: 1,026,275. Laminates. BADISCHE-ANILIN- & SODA-FABRIK A.G. Feb. 11, 1963 [Feb. 20, 1962], No. 5392/63. Heading B5N. A heat insulating and fireproof laminate is made by bonding a sheet of metal to a sheet consisting of an alkali metal silicate, e.g. sodium silicate, 20 to 70% by weight of water and 10 to 40% by weight of fibres such as glass fibres or rock wool (percentages with reference to anhydrous silicate) by pressure at a temperature between 50‹ and 150‹ C. The silicate layer may be bonded to one or both sides of the metal sheet, or a metal sheet may be bonded to both sides of the silicate layer. The sheets may be bonded together using waterglass as an adhesive.

    Abstract: Sheet material capable of absorbing and evaporating water vapour is obtained by treating vapour-permeable substrate, e.g. textiles with copolymers containing at least 5 wt.% 3-4C carboxylic acid esters with 4-8C tert alcohols and 0.1-10 equivalent % unsaturated acid with dissociation constant above 10-4 (e.g. unsatd. sulphonic acid) and heating. Polymers cleave off gaseous olefins when heated and form foam, creating carboxyl groups which impart hydrophilic character to sheet material.

    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.
