HEAT-RESISTANT PLASTIC EXPLOSIVE COMPOSITION Russian patent published in 2016 - IPC C06B25/34 C06B45/10 

FIELD: blasting operations.

SUBSTANCE: use relates to plastic explosive compositions (EC) and can be used in heat-resistant systems of initiation and detonation layouts with small sections of channels. Heat-resistant plastic EC consists of a blasting explosive substance (ES) - benzotrifuroxan (BTF), a polymer binder - a composite material based on a mixture of low-viscosity organosilicon (siloxane) rubber and polyisobutylene and a filler - an additionally reinforcing component in the form of polytetrafluoroethylene or fibrous asbestos, at the ratio of components, wt%: filler - 0.5-2.0, binder - 10-15, BTF - the rest.

EFFECT: use of a combined binding agent and an additionally reinforcement component enables to obtain a heat-resistant EC suitable for rolling, extrusion at low sections of dies and pressing at low specific pressure without heating the EC and a tool that provides safety, efficiency and environmental friendliness of technological processes of production and processing the EC.
