COMPOSITION FOR HEAT-ACCUMULATING MATERIAL Russian patent published in 1998 - IPC

FIELD: protection of instruments and equipment from repeated heating. SUBSTANCE: composition for heat-accumulating material based on mixture of solid paraffinic hydrocarbons comprises ethylene-propylene- dicyclopentadiene copolymer. Mixture of paraffinic hydrocarbons includes cerasin, stearic acid, zinc oxide, tetramethylthiuram disulfide, sulfur, mercaptobenzthiazole and diethylene glycol. The ratio of components is follows (wt parts): 100 ethylene-propylene- dicyclopentadiene copolymer; 4-6 zinc oxide; 0.9-1.5 stearic acid, 1-2 tetramethylthiuram disulfide, 1.5-2.5 sulfur; 0.5-1.5 mercaptobenzthiazole; 5-15 diethylene glycol; 250-350 ceresin. EFFECT: improved properties of the composition.
