Abstract

The invention discloses low-density high-detonation-velocity explosive and a preparation method thereof. The low-density high-detonation-velocity explosive is used for explosive welding of large-scalecopper-steel composite boards. The low-density high-detonation-velocity explosive is prepared from, 50 parts of emulsion explosive, 30 parts of perlite and 45 parts of bran. The pure explosive density of the emulsion explosive is 0.73 cm<3>, the brisance is 20 mm, and the explosive velocity is 4000 m / s. The low-density high-detonation-velocity explosive is suitable for explosive welding of the large-scale copper-steel explosion composite boards, the problem is effectively solved that large-scale copper-steel explosion composite boards are not fitted, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to an explosive with low density and high detonation velocity for explosive welding of large-area copper-steel composite plates and a preparation method thereof. Background technique [0002] Copper is an indispensable metal in our life, but the cost of simply using copper is relatively high, and it is easy to cause waste of resources. Therefore, the industrial use of copper mainly uses copper-steel composite panels to make up for the problem of high price and cost. Moreover, with the development of the domestic chemical industry, the area of ​​a single plate required for equipment manufacturing is also increasing, which brings great difficulties to explosive recombination. The requirements for copper-steel composite panels are becoming more and more stringent, and the width of the panels is also increasing. Problems such as non-fitting and low bonding strength of copper-steel after explosive welding also appear. [0003] Judgin...
