FIELD: fire safety.
SUBSTANCE: invention relates to methods of producing fire-retardant intumescent coatings. Method is realised by adding to a composition consisting binder - organic polymer solution, melamine, pentaerythritol, monoammonium phosphate, chlorine-containing polymer or oligomer products: chlorinated polyvinyl chloride resin, or a copolymer of vinyl chloride with vinyl acetate, or saponified copolymer of vinyl chloride with vinyl acetate, or chlorinated polyethylene.
EFFECT: invention enables to obtain a full foam-coke layer due to improvement of gas release thermolysis mass by stabilisation of monoammonium phosphate.
