CABLE PROTECTING MATERIAL Russian patent published in 2007 - IPC D06M13/02 H01B3/20 H01B3/28 

FIELD: production of protecting and corrosion-resistant materials by impregnating fibrous base with antiseptic and corrosion-resistant compounds.

SUBSTANCE: material is made in the form of low-twist yarn of flat section from bast-fiber or mixed filaments having linear density of 1,500-3,500 tex and twist rate of 20-50 per 1 m. Yarn is reinforced with high-strength thread consisting of synthetic filaments having linear density of 60-120 tex or bast-fiber filaments having linear density of 200-600 tex. Rupture load of reinforcing thread is 30-60% of rupture load of yarn. Material is also impregnated with compound including 12-28 wt% of liquid non-volatile or low-volatile low-viscosity petroleum products used as filler, 0.2-1.5 wt% of product of reaction of aromatic hydrocarbons with isobutylene as antiseptic.

EFFECT: increased workability and covering capacity, high fungi-resistance and strength, in particular, on usage of jute filament and Capron thread, and impregnation compound based on transformer oil and antiseptic.
