ELECTRICALLY INSULATING MATERIAL Russian patent published in 2013 - IPC H01B3/18 H01B17/00 C08L83/04 

FIELD: chemistry.

SUBSTANCE: by increasing resistance to inflammation in combustion conditions, the electrically insulating material, which is obtained from additive vulcanisation silicone rubber, simultaneously contains vinyl and hydride-containing siloxanes, a cyano-containing organophosphorus compound in amount of 40-70 pts.wt and/or modified aluminium hydroxide in amount of 10-150 pts.wt per 100 pts.wt polyorganosiloxane, filler materials and polymers with block trimethyl-containing siloxane links that are cross-linked under the action of a platinum catalyst, wherein the latter is added to the rubber mixture before use thereof. The siloxane rubber can further contain powdered quartz in amount of 10-40 pts.wt per 100 pts.wt polyorganosiloxane.

EFFECT: high resistance of the electrically insulating material to inflammation in combustion conditions.
