METHOD TO MANUFACTURE COMPOSITE EXPLOSIVE FOR EXPLOSION WELDING AND COMPOSITE EXPLOSIVE Russian patent published in 2013 - IPC C06B23/00 B82B1/00 

FIELD: blasting.

SUBSTANCE: method to manufacture a composite explosive for explosion welding, includes preparation and mixing of explosive components, at the same time prior to mixing the explosive component is recrystallised to produce a nanodisperse powder from an organic dissolvent in the form of compounds from the group of dimethyl formamide, dimethyl sulfide or acetone into water, the produced dispersion is stabilised under higher temperature of not more than 100°C with further evaporation of the organic dissolvent and drying of the residue, which is then mixed with an inert filler, and the composite explosive is formed. The substance produced by this method as an explosive component contains tetranitropentaerytrite, or octogene, or hexogene in the form of pre-transformed to ultradisperse condition with particle size of not more than 10^-6-10^-8 m in amount of 30-70 wt % and a powdery inert filler in the form of sodium bicarbonate - balance.

EFFECT: invention provides for the possibility to arrange a link through explosion of fine parts and thin-film elements of assembly structures, for instance, thin plates or foil, without deformation and damage due to provision of minimisation of explosive layer and reduction of critical detonation layer.
