COMPOSITION FOR HEAT-ACCUMULATION MATERIAL Russian patent published in 2004 - IPC

FIELD: heat-insulation materials.

SUBSTANCE: invention relates to compositions for heat-accumulation materials used as protective means against repetitive heatings of devices and equipment as well as warming elements in protective clothing or indoors. Composition contains, wt parts: ethylene/propylene/dicyclopentadiene copolymer 100.0, chlorosulfurized polyethylene 5.0-20.0, stearic acid 0.5-1.5, zinc oxide 4.0-6.0, pentamethylthiurame disulfide 1.0-3.0, sulfur 1.5-2.5, mercaptobenzothiazole 0.5-1.5, diethylene glycol 5.0-15.0, and solid hydrocarbons 250.0-400.0. The latter are selected from paraffin, ceresin, wax, and synthetic higher primary fatty alcohols.

EFFECT: reduced stickiness, widened assortment of stabilization temperatures at realization of heat effects, and lowered compaction pressure.
