METHODOLOGY OF PRODUCING BIOPOSITIVE COMPOSITES USING LIGNIN-CONTAINING WASTES

The article discusses the possibility of obtaining biopositive, energy-efficient building materials using local raw materials and waste with a given set of performance properties. The influence of the microstructure of organic fillers on the properties of materials was studied and criteria for the use of a combined multicomponent organic filler were determined. Test results and multifactor analysis are presented; it is determined that the use of polyfractional plant filler can improve the strength characteristics of the material. The mechanisms of formation of the adhesive shell of polystyrene foam granules have been studied. The efficiency of modification of aqueous dispersions of dimethyl ketone and carboxylic acid derivatives with nanosized additives was studied using thermodynamic curves. Physico-chemical processes and structure formation in the composite material have been studied.
