SELF-EXTINGUISHING COMPOUND Russian patent published in 1995 - IPC

FIELD: insulating materials. SUBSTANCE: compound has additionally epoxy diane resin, product of dehydrochlorination of epichlorhydrin with water and tricresyl phosphate at the ratio of components, mas. p. epoxy diane resin ED-20 20-35; product of condensation of dicarboxylic oligodiethylene glycol sebacate with epoxy diane resin 5-25; product of dehydrochlorination of epichlorhydrin with water 20-40; product of condensation of epichlorhydrin with 2,4,6-tribromoaniline 20-35; tricresyl phosphate 5-10; isomethyltetrahydrophthalic anhydride 63-82, and 2,4,6-tric-(dimethylaminomethyl)-phenol 0.1-0.2. Proposed composition shows rather low viscosity (30-40 s) at 25 25 ± 5^°C 5 C that ensures to carry out transformer impregnation under the room conditions. EFFECT: enhanced quality of compound. 2 tbl
