FIELD: chemistry. ^ SUBSTANCE: invention concerns construction material production, particularly manufacturing of high-performance noncombustible heat insulation materials based on liquid glass and natural silicates. Composition for foam silicate material includes, wt %: liquid glass 70-90; filler 5-25; saturated CaCl2 and AlCl3 solution 3-5. Method of obtaining foam silicate material involves mixing of liquid glass with fine filler in a mixer, granulation of obtained mix in calcium chloride CaCl2 solution, granule drying, granule placement in metal mould and boiling in closed mould vessel in furnace to obtain material with given dimensions. Granulation is performed by dipping the mix through separation funnel into saturated solution of CaCl2 additionally including aluminium chloride AlCl3, and tempering of mix in solution for 20 minutes, drying is performed after filling mould, in drying chamber at 60°C for 40 minutes, boiling is performed in furnace at 350-380°C for 1 hour at the described component ratio. ^ EFFECT: improved durability properties preserving water resistance, stabilisation of material properties, reduced power cost of production. ^ 2 cl, 1 tbl, 4 ex |
