Water-resisting colloidal emulsion explosive and preparation method thereof

Abstract

The invention discloses water-resisting colloidal emulsion explosive. The water-resisting colloidal emulsion explosive is prepared from the following components in parts by mass: 88-96 parts of ammonium nitrate, 6-10 parts of sodium nitrate, 4-8 parts of potassium nitrate, 3-5 parts of urea, 1-3 parts of an emulsifying agent, 9-11 parts of water, 5-7 parts of an oil phase, 4-6 parts of expanded perlite and 0.5-1.5 parts of mixed rare earth. The invention further discloses a preparation method of the water-resisting colloidal emulsion explosive. When the product is used, the product has low sensitivity on mechanical and thermal effects; the medicine filling density can be adjusted; the product has good water resistance and can be stored in flowing water, even deep water; the detonation sensitivity can be adjusted so that a relay detonator is used for detonating when necessary from the detonation of a standard detonator; no dust is generated and no electrolysis and oil seepage phenomena occur; and meanwhile, the system is close to zero oxygen balance, the toxicity of gas released in a detonation process is small, raw materials are easily available and the construction cost is relatively cheap.

Description

[0002] Emulsion explosives, the main type of industrial explosives to be replaced, have developed rapidly in China in recent years, and their output has increased year by year. At present, there are hundreds of emulsion explosive manufacturers in China, with an annual production capacity of several million tons. The variety of emulsion explosives is becoming more and more More and more, the product quality is gradually improved. At present, a variety of new explosives with excellent performance, stable storage performance, fewer components and lower cost have emerged, and gratifying progress has also been made in production technology and production equipment technology. The continuous research and development and breakthrough of new technologies and new equipment have improved the level of production technology, and the fully continuous production line monitored by microcomputers has also come out. After decades of development, the output, quality, performance and production technology of emulsion explosives in my country have reached a higher level. The level of research on product formulations is comparable to the existing international level. However, in terms of production scale, production technology and tooling equipment, there is a big gap compared with international advanced technology, which needs to be improved and improved to meet the needs of my country's industrial Explosives Development Needs
