Abstract RU 2083624 C1

FIELD: production of protective coatings for cables being prepared by applying of bitumen compositions on fabric. SUBSTANCE: fabric is treated by solution of bitumen-polymer composition in organic solvent, the process is followed by heat treatment of the material to remove solvent. Compositions comprise 42-50 mass % of solid bitumens having softening temperature higher than operation temperature of articles, 1-1.5 mass % of polymer and solvent up to 100. Mentioned above polymer represents butadiene-styrene, butadiene-α-methylstyrene thermoelastic plastic or butyl rubber. If it is necessary then antiseptic (its quantity being up to 5 %) may be added into said composition. EFFECT: provided homogeneous impregnation, excluded unnecessary stickiness. 5 tbl
