HEAT-ACCUMULATION MATERIAL COMPOSITION Russian patent published in 2002 - IPC

FIELD: heat-accumulation materials. SUBSTANCE: invention relates to materials that can be used as protection means against repetitive heatings of high temperature-sensitive instruments and equipment as well as heating elements in protective clothing or in rooms. Composition contains, wt.pts: polymer, 100; stearic acid, 0.5-1.5; zinc oxide, 4.0-6.0; tetramethylthiuram disulfide, 1.0-3.0; sulfur, 1.5-2.5; mercaptobenzothiazole, 0.5-1.5; diethylene glycol, 5.0-15.0; paraffin C20-C31, 250.0-350.0. Said polymer is a copolymer of ethylene, propylene, and diene (ethylidenenorbornene or dicyclopentadiene). EFFECT: achieved stabilization temperature 50-55 C at high summary heat effect within narrow temperature range with strength properties and dimensional stability preserved. 3 cl, 1 tbl, 3 ex
