METHOD FOR PRODUCING AN ELECTRICALLY CONDUCTIVE POLYURETHANE COMPOSITE MATERIAL AND THE MATERIAL Russian patent published in 2021 - IPC C08L75/04 C08K3/04 C09K3/16 C01B32/159 B82Y30/00 H01B1/12 

FIELD: composite materials.

SUBSTANCE: present invention relates to an electrically conductive polyurethane composite material and to a method for its producing and can be used in the manufacture of products and coatings made of polyurethane composite materials with the required electrical conductivity. The method for producing an electrically conductive polyurethane composite material by reacting organic polyisocyanates (A) with one or more compounds containing NCO-reactive groups (B) includes a stage of mixing a concentrate of carbon nanotubes with compounds (B) or with polyisocyanates (A) or with a mixture containing organic polyisocyanates (A) and compounds (B), with an energy input of less than 0.5 kWh per 1 kg of the mixture, with the content of carbon nanotubes calculated by the sum of the masses (A) and (B) less than 0.1 wt.%.

EFFECT: production of electrically conductive composite polyurethane materials with a specific volumetric electrical resistance of less than 10⁹ ohm⋅cm, without degradation of the components of the polyurethane material during its mechanical processing.
