METHOD OF PRODUCING STRUCTURAL COMPOSITION BASED ON PRIMING MIXTURE BY HARDENING

摘要

FIELD: chemistry.SUBSTANCE: invention increases tensile and compression strength of priming coats, as well as water-resistance thereof while reducing binder consumption to 0.003-0.012 wt %. The effect is achieved by using cation-active imidazoline and polyacrylic acid in the composition, which form an insoluble polyelectrolyte interpolymer complex during chemical reaction.EFFECT: invention relates to a method of producing a stable structural composition based on a priming mixture of clay and sand as natural filler and can be used for industrial purposes for producing moulding agents, accelerated hardening of priming coats and endowing priming coats with hydrophobic properties.1 tbl
