FIELD: polymer materials as protective coatings.
SUBSTANCE: invention relates to preparing anticorrosion, fire-resistant, and heat-retention composition for use in oil and gas production industry, petrochemical industry, in municipal economy and other areas, where protection of surfaces against corrosion, heat, and inflammation are required as well as to application of composition as protective coating for metal, concrete, and, in particular, for protection of pipelines operated in permafrost regions, under water surface, and at large temperature and pressure gradients inside and outside pipelines. Composition is composed of 5-95% epoxide resin, 3-65% hardener, 5-95% hollow microspheres, and 0-20% auxiliary additives. Hollow microspheres are selected from group consisting of glass hollow microspheres, ceramic hollow microspheres, polymeric microspheres, hollow man-made microspheres and mixtures thereof. Microspheres are dimensioned within a range 10 to 500 μm with loose density between 650 and 50 kg/m3.
EFFECT: improved performance characteristics of coatings.
