FIELD: chemistry.
SUBSTANCE: method of producing heat-resistant material for protective coating involves dissolving a polymeric binder in a solevent, where the binder is in form of poly(o-hydroxyamide), which is a product of polycondensation of dichloride of isophthalic acid with 3,3'-dihydroxy-4,4'-diaminodiphenylmethane in a solvent in molar ratio of reagents ranging from 1:1:7 to 1.05:1:15, and mixing with carbon nanofibres or carbon nanoclusters, obtained through hydrolysis of methane on a Ni/MgO catalyst with length of fibres from 50 to 100 mcm and diametre from 20 to 60 nm until obtaining a homogeneous composition.
EFFECT: obtained finished material is heat-resistant, is highly adhesive and has protective properties when deposited on surfaces of varying chemical nature.
