Novel low-detonation-velocity explosive applicable to stainless steel composite and preparation method thereof

Abstract

The invention discloses a novel low-detonation-velocity explosive applicable to stainless steel composite and a preparation method thereof; the preparation method comprises the steps: taking 60 parts by weight of a rock powdery emulsion explosive with the bulk density of 0.58 g*cm<-3>-0.62 g*cm<-3>, the detonation velocity of 3500 m/s-3700 m/s, the brisance of 15 mm-17 mm, the sympathatic detonation distance of 9 cm-11cm and the capacity for work of 360/ml, taking 36 parts by weight of sand with the bulk density of 1.40/g*cm<-3> and the particle size of 300 mesh, putting the two raw materials into a drug mixing machine, stirring for 3-5 minutes, then taking 17 parts by weight of chaff with the bulk density of 0.50/g*cm<-3> and the particle size of 300 mesh, putting the chaff into the drug mixing machine, stirring for 20 minutes, fully stirring evenly, and then detecting the density and the detonation velocity of the product. The sand is used for reducing the detonation velocity, and the chaff is used as a density regulator for regulating the density of the mixed explosive; the effective density of the rock powdery emulsion explosive is reduced by the combined action of the sand and the chaff; the novel low-detonation-velocity explosive obtained by mixed loading of the raw materials in proportion can increase the production efficiency and solves problems of unfit large-area stainless steel-steel composite plates.

Description

technical field [0001] The invention belongs to the field of steel compounding, in particular to a novel low detonation velocity explosive suitable for stainless steel compounding and a preparation method thereof. Background technique [0002] Stainless steel not only has good corrosion resistance, but also has many characteristics such as good appearance, because stainless steel plate has the following characteristics: beautiful surface and diversified use possibilities; good corrosion resistance, durable than ordinary steel; good corrosion resistance High strength, so the possibility of thin plate use is great; High temperature oxidation resistance and high strength, so it can resist fire; Normal temperature processing, that is, easy plastic processing; Because no surface treatment is required, it is simple and easy to maintain; Clean, high finish; Welding performance Well, so it is widely used in the stone automobile industry, tableware, kitchen equipment, electrical appl...
