Abstract

The invention relates to a preparation method of a low-detonation-velocity and low-density explosive applicable to nickel-steel compounding. The preparation method comprises the following steps: detecting detonation parameters of an emulsified explosive; if the detonation parameters accord with pre-set parameters, carrying out the following steps: adding the emulsified explosive and pearlite into an explosive mixing machine at the same time and uniformly stirring, wherein the weight ratio of the emulsified explosive to the pearlite is 58 to 38; adding bran into the explosive mixing machine and sufficiently and uniformly mixing, wherein the weight ratio of the emulsified explosive to the pearlite to the bran is 58 to 38 to 15; detecting the density and detonation velocity of a product in the explosive mixing machine; and considering the product with the density of 0.84g / cm<3> and the detonation velocity of 2000m / s-2200m / s as a qualified product. A nickel-steel compound plate obtained by detonation compounding of the explosive has the minimum shearing strength tau b which is more than or equal to 210Mpa; except a detonator shadow region, the fitting rate reaches 100%; and adverse effects on the detonator shadow region are eliminated through avoiding a useless part of a detonating point in the compound plate.

Description

technical field [0001] The invention belongs to the field of new energy development, and in particular relates to a method for preparing a nickel-steel composite low-detonation-velocity-low-density explosive. Background technique [0002] Nickel and nickel alloys have excellent corrosion resistance and heat resistance, and are widely used in harsh corrosive environments, showing effective resistance. In many cases, these corrosive conditions are irresistible to materials such as stainless steel or super stainless steel. Nickel itself is a multifunctional corrosion-resistant material with the characteristics of high strength, high plasticity, good ductility and forgeability. As an alloying element, nickel has metallurgical compatibility with other metal elements in most composition ranges, and has become many binary, ternary alloys and other complex alloy systems. Nickel and nickel alloys are widely used in chemical industry, alkali making, metallurgy, Pressure vessels, hea...
