FIELD: chemistry.SUBSTANCE: invention relates to polyethylene composition, intended for obtaining slow-burning construction materials of general technical and engineering-technical purpose. Composition contains high-density polyethylene and filling agent with particle size 0.145-0.315 mm in quantity 30-50 wt. p. per 100 wt. p. of polyethylene. Filling agent represents mixture of crushed basalt and crushed basalt wool.EFFECT: obtained compositions possess increased output of coke residue at 600°C, Vicat softening temperature, temperature of destruction starting, toughness, bending strength, as well as high weight loss during combustion.1 tbl, 5 ex |
