FIELD: chemistry.
SUBSTANCE: invention relates to heat-insulating coatings. The anticorrosion and heat-insulating coating is made from a water-suspension composition with viscosity ranging from 1 to 100 Pa·s. The water-suspension composition contains a mixture of 5 to 95 vol. % polymer binder with 5 to 95 vol % hollow microspheres. The polymer binder is a water-emulsion polymer latex composition, which contains from 10 to 90 vol. % (co)polymer, selected from a group which includes acrylate homopolymer, styrene-acrylate copolymer, butadiene-styrene copolymer, polystyrene, butadiene polymer, polychlorovinyl polymer, polyurethane polymer, vinylacetate polymer or copolymer, or their mixture and from 10 to 90 vol % mixture of water and surface active substance. The hollow microspheres are in form of microspheres with different sizes from 10 to 500 micrometres and different packed density from 50 to 650 kg/m3, selected form a group which includes hollow glass microspheres, hollow ceramic microspheres, hollow polymer microspheres, hollow technogenic microspheres or their mixture. The water-suspension composition also contains a mixture of polyatomic alcohol with polybasic carboxylic or amino acid in equimolecular ratio.
EFFECT: longer service life of composition in harsh climatic and industrial conditions.
