PAINT COMPOSITION WITH THERMO-, FIRE-PROTECTIVE PROPERTIES

摘要

FIELD: chemistry. ^ SUBSTANCE: paint with thermo-, fire-protective properties contains (wt %): binder based on acrylic (co)polymers and/or silicone resins and organosoluble polyurethanes - (20-40), filler in form of a mineral component - (10-30), antipyrene additive - (10-20), modifying additive in form of ceramic and/or glass microspheres with diameter of 20-150 mcm -(10-30) and an organic solvent - the rest. The paint composition additionally contains bentonite powder, intercalated with cobalt Co2+ ions and/or cerium Ce3+ ions in amount of 3-7 wt %. ^ EFFECT: invention increases stability of the formed protective paint coating to thermal-oxidative reactions, improves environmental safety, fire-resistance of the protective coating and endows said coating with bactericidal properties. ^ 7 cl, 2 dwg, 1 tbl
