FIELD: chemistry.SUBSTANCE: invention relates to construction, particularly to production of construction materials and can be used to produce self-supporting heat insulating materials, for heat-insulating walls, ceilings, partition walls etc, primarily for rural and individual construction. The composition for producing self-supporting heat insulating material contains wood processing wastes - sawdust, gypsum plaster, a foaming additive and water, with the following ratio of components (wt %): sawdust 10.75-14.5, gypsum plaster 36.9-50.0, foaming additive 0.55-0.6, water 37.2-51.8. The technique of producing the composition includes the following: moistening sawdust using 10% of the water needed to produce the material; preparing a foam solution by adding the foaming additive to the remaining water and thoroughly mixing; gradually adding the gypsum plaster and the moist sawdust to the obtained foam while stirring constantly.EFFECT: obtaining self-supporting heat insulating material, having high heat insulating properties, simple composition, wide raw material base and low cost.2 cl, 1 tbl |
