FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to the method of producing sealer-lubricant that comprises selecting diblock copolymer from the group of styrene-ethylene/butylene or styrene-ethylene, propylene and combination thereof. It also includes and combining diblock copolymer with mineral oil at temperature lower than that of glass transition of styrene zones. Proposed method can comprise also filtration of styrene-rubber diblock copolymer to produce particles sized to less than 1 mm.
EFFECT: sealer with higher creep resistance at 70 to 80°C.
