FIELD: chemistry.

SUBSTANCE: invention relates to composition of two-component epoxy-polyurethane potting electrically insulating compound and method of obtaining thereof. Component "A" consists of monomer-oligomer mixture of polyepoxides, consisting of bisphenol A diglycidyl ether, bisphenol A monoglycidyl ether and bisphenol A or bisphenol A diglycidyl ether, bisphenol A monoglycidyl ether, bisphenol A and product of binding 1 mole of bisphenol A monoglycidyl ether to 1 mole of bisphenol A diglycidyl ether, polyols, consisting of mixture of triglycerides of ricinoleic, stearic, oleic, linoleic and linolenic acids, technological additive, disperse mineral filler and colourant. Component "B" consists of mixture of methylene diparaphenylene diisocyanate and dichloroanhydride of methylene diparaphenylene dicarbamidic acid. Described is method of obtaining epoxypolyurethane compound by successive addition of technological additive, preliminarily heated and thermally processed polyol, filler and colourant to polyepoxide with formation of component "A" and further addition of component "B" at temperature 20°C.

EFFECT: increase of viability and reduction of initial viscosity of epoxypolyurethane compound, which makes it possible to realise potting of large-volume products.
