FIELD: building material industry, particularly plastic material production and for heat-insulation and structural material manufacturing.
SUBSTANCE: mix comprises filler, grinded thermoplastic waste material, namely polyethylene terephthalate and polyethylene waste, as well as mineral component. The filler is burnt quartz sand. The mineral component is chalk and fine silicon oxide. All above components are taken in the following amounts (% by weight): burnt quartz sand - 30-40, polyethylene terephthalate waste - 60-50, polyethylene waste - 5.0-10, chalk - 2.5-3.5, fine silicon oxide - 2.5-2.0. Thermoplastic waste material used for mix production is preliminarily grinded along with thermomechanical treatment thereof in the presence of chalk and then is atomized in the presence of fine silicon oxide.
EFFECT: increased flexural strength and impact elasticity, as well as decreased water absorption capacity of article formed of above mix.
