FIELD: chemistry.
SUBSTANCE: invention relates to compositions of construction compositions and can be used to produce composite materials. Mixture for producing composite construction materials, containing components of municipal waste and including wastes of polyethylene terephthalate and polyolefins, modified copolymer of ethylene and vinyl acetate and finely dispersed mineral filler with content of calcium and magnesium carbonates of not less than 80 %, according to the disclosed technical solution additionally contains wood filler obtained from wood municipal waste by their preliminary grinding, treatment in 20 % sodium silicate solution at ratio of 100 wt. parts of wood municipal waste 18…20 wt. parts of said solution and drying, with following ratio of components, wt. parts: polyethylene terephthalate wastes – 75, polyolefin wastes – 25, modified ethylene and vinyl acetate copolymer – 5, mineral filler – 0–160, wood filler – 8–48.
EFFECT: improved heat-engineering characteristics of construction articles, reduced weight of articles, recycling of polymer municipal wastes and wood communal wastes.
