FIELD: chemistry.
SUBSTANCE: invention relates to a composition for producing a chalk concentrate and can be used in production of chalk additives for different industrial applications, including production of plastic articles, composite and construction materials. Composition for producing chalk concentrate consists of: calcium carbonate from 30 to 70 wt.%, sodium chloride from 10 to 25 wt.%, stearic acid from 10 to 20 wt.%, polyethylene grades LDPE 1000 or LDPE 5000, or HDPE 5000, or HDPE 6000, or LLDPE 3000 from 5 to 15 wt.% and a wax additive in amount of 5 to 10 wt.%.
EFFECT: improved physical and chemical properties of the chalk concentrate, which includes high strength, hydrophobicity and thermal stability of the product, as well as broadens use thereof in different industries such as production of plastic, composite and construction materials.
