(54) RAW MATERIAL MIXTURES FOR THE MANUFACTURE OF PENOSILICATE PRODUCTS

 The invention relates to silicate-based thermal insulation materials and can be used in construction as a thermal insulation and anti-corrosion material. The known raw material mixture for the manufacture of heat insulating material, including liquid glass, a gasifier, fly ash; alkali and aero force l. Closest to the technical solution of the invention is a raw mix for the production of foam-silicate products, including liquid glass, aluminum powder, a hardening activator, and fly ash 2. The temperature of the swelling of the known mixtures, although reduced but not sufficient, is achieved. that the raw material mixture for the manufacture of foam silicate products, including water glass, a / nyjipy, activator of hardening and fly ash, contains additionally ethyl hydro siloxane liquid and oleic acid, and as an activator of hardening sodium silicate fluoride npii, the following ratio of components, by weight, is wt. Liquid glass 20-37 Alumina powder 1-3 Sodium fluorosilicate 2-3 Ethyl hydrosiloxane liquid1-3 Oleic acid 1-4 Fly ash The rest of the transfer product from pre-. Raw mixture is prepared as follows. Liquid glass with a specific gravity of 1.45 and a silica module 2.8 warms up. Ethyl hydrosilocyan liquid is then introduced and, after stirring for 1 min, a mixture of dry components: fly ash, aluminum powder and sodium chloride is added. The mixture is stirred until a homogeneous mass is obtained. Oleic acid is added and again rebounded for 2 mmn. The resulting mixture is poured into form.Sh and kept for 8 h at. The content (weight,%} of the various compositions of the Second World War proposed by the overseas mixture is given in the table.
