Abstract
The invention discloses a heatproof mixing explosive which comprises the following raw materials: by mass, 93.0%-95.0% of a single-compound explosive; 2.0%-3.0% of fluorine rubber; 0.5%-1.0% of stearic acid; 1.0%-2.0% of rubber slurry; and 0.3%-0.5% of graphite. The single-compound explosive is a mixture of LLM-105 and ATB; the fluorine rubber is FPM2311, FPM2603 or FPM246G; and the rubber slurry is polytetrafluoroethylene emulsion, polyacrylate emulsion or styrene-acrylonitrile copolymer emulsion.
