Problems solved by technology

Although the powdery emulsion explosive produced by spray milling has high explosive performance and good water resistance, in order to control the water content in the production process, a high temperature of more than 130°C, or even as high as 150°C is used, and the solution pressure is increased. To increase the solubility of ammonium nitrate, and spray milling consumes a lot of energy and costs
[0004] Although the powdery emulsion explosives at this stage have excellent working ability, their brute force is even higher than that of TNT, and they have certain water resistance, but the underwater explosion experiments show that its explosion shock wave peak value, impulse, energy and other indicators are still slightly lower. Insufficient

Abstract

The invention discloses a rock powder emulsion explosive for civilian use, which is made of the following raw materials in parts by weight: ammonium nitrate: 74-83%, calcium nitrate: 3.5-4%, oil phase: 3.2-3.5%, and composite emulsifier: 3-3.5%, urea: 2%, composite flame suppressant: 5-8%, porous granular ammonium nitrate: 0.5-3%, titanium hydride: 1-2%, mixed rare earth: 0.3%; the production process of the emulsion explosive In order to prepare water phase, oil phase, emulsification, add components to the emulsification matrix, negative pressure drying to make powder, add components to the powder and mix, and then make rock powder emulsion explosive. The composition and production process of the emulsion explosive of the invention can improve the detonation performance of the emulsion explosive, reduce the content of toxic gas, and produce a high-performance, safe rock powder emulsion explosive with little pollution.

Description

technical field [0001] The invention belongs to the technical field of explosive preparation, and relates to a rock powder civil emulsion explosive and a production process thereof. Background technique [0002] Permissible explosives in coal mines are an important part of industrial explosives in my country. They are classified according to the conditions of use of industrial explosives and are specially designed for use in underground coal mines where there is a risk of combustible gas and coal dust explosions. [0003] Powdered emulsion explosive, referred to as PEE, is a new type of powdery (water-resistant) water-containing industrial explosive developed in recent years. The fine droplets are the dispersed phase, and the oil phase solution composed of specific carbonaceous fuel and emulsifier is the continuous phase. Under certain process conditions, the water-in-oil emulsion is formed by strong shearing. A powdery ammonium nitrate emulsion explosive made. Although th...
