Gel-type emulsified explosive and preparation method thereof

Abstract

The invention discloses gel-type emulsified explosive which comprises the following components in percentage by mass: 60-67% of ammonium nitrate, 6-10% of sodium nitrate, 5-10% of potassium nitrate, 3-5% of a crystal form modifier, 5-10% of a flame inhibitor, 2-4% of urea, 0.7-1.5% of an emulsifier, 0.4-0.6% of an emulsifying auxiliary agent, 10-17% of water, 3-5% of an organic oil-phase material, 0.3-0.5% of a foaming agent, and 0.3-0.5% of an adhesive. The gel-type emulsified explosive is simple in process, easily obtainable in raw material, relatively low in price, low in cost, great in power and small in environment pollution, and moreover the preservation time is prolonged.

[0002] Emulsion explosives are developed based on the theory of emulsions. Usually water-insoluble hydrocarbon fuels are used as the continuous phase. At present, there are hundreds of emulsion explosive manufacturers in China, with an annual production capacity of millions of tons. The variety of emulsion explosives is more There are more and more products, and the product quality is gradually improving. 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 the production process and production equipment technology. , The continuous research and development and breakthrough of new technology and new equipment have improved the level of production technology, and the fully continuous production line monitored by computer has also come out. After decades of development, the output, quality, performance and production technology of emulsion explosives in my country have reached a relatively high level. At a high level, the 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 the international advanced technology, which needs to be improved and improved to meet the needs of our country.
