Novel low-detonation velocity explosive suitable for titanium material compounding, and preparation method thereof

Abstract

The invention discloses a novel low-detonation velocity explosive suitable for titanium material compounding, and a preparation method thereof. The method comprises the following steps: taking 40 parts by weight of a rock powdery emulsion explosive with the bulk density of 0.58-0.62g.cm<-3>, the detonation velocity of 3500-3700m / s, the brisance of 15-17mm, the gap distance of 9-11cm and the work capacity of 360 / ml, taking 45 parts of sands with the bulk density of 1.40g.cm<-3> and the particle size of 300 meshes, putting above taken materials in a medicine mixer, stirring the materials for 3-5min, taking 7 parts of bran with the bulk density of 0.50g.cm<-3> and the particle size of 300 meshes, putting the taken bran in the medicine mixer, stirring the obtained mixture for 20min until fullness and uniformity, and detecting the density and the detonation velocity of the above obtained product. The sands are used to reduce the detonation velocity, and the bran is used as a density adjusting agent to adjust the density of the obtained mixed explosive; and the effective density of the rock powdery emulsion explosive is reduced through synergism of the sands and the bran, and the novel low-detonation velocity explosive prepared through mixing above materials in proportion can improve the production efficiency, and solves the problem of lack-of-fit of large-area titanium-steel composite plates.

Description

technical field [0001] The invention belongs to the field of titanium material compounding, in particular to a novel low detonation velocity explosive suitable for titanium material compounding and a preparation method thereof. Background technique [0002] Titanium has high strength, and the tensile strength of pure titanium can reach up to 180kg / mm 2 . Some steels are stronger than titanium alloys, but the specific strength (the ratio of tensile strength to density) of titanium alloys exceeds that of high-quality steel. Titanium alloy has good heat resistance strength, low temperature toughness and fracture toughness, so it is mostly used as aircraft engine parts and rocket and missile structural parts. Titanium alloys can also be used as fuel and oxidant storage tanks and high-pressure containers. Titanium alloys have been used to make automatic rifles, mortar seat plates and the launch tubes of recoilless guns. In the petroleum industry, it is mainly used for various...
