The results of the development of a raw mixture, which contains a filler obtained by grinding a mixture of small-sized wood waste based on light dirt varieties of coniferous and deciduous species, and a binder obtained by dissolving the waste products from polystyrene foam in methylene chloride, are presented. This mixture allows cold mixing and pressing followed by heat treatment at the boiling point of the solvent. In the course of experimental studies, the influence of the ratio of the mixture components and the pressing pressure on the basic properties and structure of the obtained composite material was established. The composition of the raw material mixture and the pressing were selected to ensure low thermal conductivity in combination with low values of water absorption and swelling density and strength compliant with regulatory requirements. Received thermal insulation material for construction purposes from wood and polymer waste, characterized by large volumes of formation and high rates of accumulation.
