Insulation composition, insulating product, method of their manufacturing and component product for the electrical cable on their basis

FIELD: chemistry.

SUBSTANCE: insulating compound is proposed, mainly for the manufacture of components for the cable industry, which contains: 70-100 parts by volume of a polymer material, 5-30 parts by volume of a ceramic filler (2), the surface of which is treated with a bifunctional coupling agent in an amount of 0.1 wt % to 4 wt %, based on the ceramic filler, 0.1 to 5 parts by volume of the crosslinking agent, 0 to 6 parts by volume of the conductive carbon powder (3); And 0-6 bulk fractions of whiskers (4) ZnO. The method of manufacturing an insulating composition comprises surface treatment of a ceramic filler with a bifunctional coupling agent, followed by its mixing with a polymeric material and a crosslinking agent in the presence of ZnO.

EFFECT: improvement of dielectric strength, heat resistance, durability and reliability of cable products manufactured from material declared insulation composition.

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.
