PEAT-POLYMER MIXTURE FOR MAKING HIGH-FIRE RESISTANCE HEAT-INSULATION ARTICLES

摘要

FIELD: chemistry.SUBSTANCE: invention relates to compositions of cement-based crude mixtures used to produce heat-insulation construction materials characterised by high fire-resistance. The peat-polymer mixture contains three components, wt %: peat which is nano-modified with a suspension of polyvinyl acetate and cyclone dust from cleaning industrial air (dry polyvinyl acetate in amount of 4-6% of the mass of peat and dust - 2-3%) 25-35%, portland cement CEM-I-42.5 35-45, water 25-35.EFFECT: invention improves strength properties with the same density and heat-conductivity, increases uniformity of the structure and longevity of the heat-insulation material.1 tbl
