THERMOPLASTIC PYROTECHNIC COMPOSITION FOR ELASTIC BLASTING FUSE POSSESSING HIGHER SENSITIVITY TO FIRE RAY Russian patent published in 2001 - IPC

FIELD: pyrotechnic compositions intended for producing elastic blasting fuses. SUBSTANCE: pyrotechnic composition comprises as oxidizer, fluorine-containing organic rubber for attaining high thermoplastic properties, increasing thermal resistance, water resistance and strength. In order to decrease inflammation temperature and reduce burning rate, composition comprises, as fuel, silicocalcium, and as oxygen-containing oxidizer, composition comprises lead oxide. In order to increase strength of blasting fuse, composition comprises fluoroplastic, ratios of components is as follows, wt.%: silicocalcium, 20-30; fluorine-containing organic rubber, 13-25; fluoroplastic, up to 5.0; and lead oxide, the balance. EFFECT: higher thermal resistance, mechanical strength and moisture resistance of blasting fuse. 5 cl, 1 tbl, 20 ex
