Abstract

The invention relates to a preparation method of a high detonation velocity and low density explosive for copper-steel compounding. The preparation method comprises detecting whether the pure density, brisance and detonation velocity of an emulsion explosive satisfy factory explosion parameters, adding the emulsion explosive and perlite into a mixing machine together according to a weight ratio of 50: 45 when the emulsion explosive has the eligible explosion parameters, carrying out uniform stirring, adding bran into the mixing machine, fully stirring the mixture, wherein a weight ratio of the emulsion explosive, perlite to bran is 50: 30: 45, and detecting product density, brisance and detonation velocity in the mixing machine, wherein the product with the density of 0.78-0.81g / cm<3>, the intensity of 12-14mm and detonation velocity of 2400-2500m / s is an eligible product. The copper-steel composite plate obtained by preparation of the explosive has minimum shear strength tau b of greater than or equal to 140Mpa, and has a bonding rate of 100% in the area except a detonator shadow region.

Description

Technical field [0001] The invention belongs to the field of new energy development, and specifically relates to a preparation method of a high detonation velocity and low density explosive suitable for copper-steel composite. Background technique [0002] Copper is a transition element, chemical symbol Cu, English copper, atomic number 29. Pure copper is a soft metal, the surface is reddish orange with metallic luster when it is just cut, and the simple substance is purple-red. Good ductility, high thermal conductivity and electrical conductivity, so it is the most commonly used material in cables and electrical and electronic components. It can also be used as a building material and can be composed of many alloys. Copper is a non-ferrous metal closely related to humans. It is widely used in electrical, light industry, machinery manufacturing, construction industry, defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materia...
