Abstract
The possibility of obtaining thermal insulation based on pine bark as a structure-forming material is considered. The granulometric composition was studied with the determination of the percentage of fractions depending on the thickness of the pine bark. The coefficient of thermal conductivity of crushed bark by fractions is determined to optimize the particle sizes of the structure-forming material of thermal insulation boards. Modified liquid glass and rosin were used as binding components. The introduction of rosin in the form of fine powder made it possible to reduce the thermal conductivity coefficient of rigid plates on a large fraction (5–8 mm) to 0.051 W / (m×°C) at a density of 304 kg/m3. The thermal conductivity coefficient of compositions on rosin decreased by 10–13% compared to samples on liquid glass.
