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: In the prodn of cellular materials from thermoplastics (I) with X-ray crystallinity 15 wt.% at 25 degrees C by blending (I) with a gas-liberating blowing agent (II), heating in a gas-tight closed mould to a temp. above the decompsn temp. of (II) cooling below the softening point of the melt under press. and expanding at atmos or reduced press. above the softening point of (I), the blend is heated in an autoclave under an inert gas press. higher than the press. resulting from the decompsn of (II). The foam has bulk density 20-150 (30-60) g/l and has fine, mainly closed cell structure, with cell size gen. 0.1 mm. It can be used for thermal and acoustic insulation, as core materials for composite boards and as packing material. The technique eliminates the need to use a high press. which is costly and allows the prodn of larger mouldings.
