Problems solved by technology

[0002] The ammonium oil explosives in the powdery ladderless explosives currently produced in China have low detonation sensitivity. When detonating, not only a relay detonator is required to detonate, but the explosive performance is low and the cost of explosives is high.
In recent years, there have been attempts to modify ammonium nitrate, composite oil phase and wood powder by adding various additives, such as No. 00123170.7, name: "Industrial Powder Ladderless Explosive", adding asphalt and other modifiers; 00126110. No. x, name: "Preparation method of industrial powdery industrial explosives", modified by adding additives such as composite oil phase, octadecylamine acetate modified reducing agent, etc. The wheel milling method is used for intermittent trial production, and it is still used for continuous automatic production. The explosive performance, storage performance and moisture-absorption and water-resistance of the product are not very stable and reliable. The portion requirements are strict, and the safety in the production process is poor

Abstract

The invention discloses a rock-type modified non-TNT powder industrial explosive and a preparation process, the compound additive and waterrepellent agent are arranged into the ammonium nitrate, wood flour and compound oil phase; the compound additive is composed of organic boron surface active agent, 18 hydrochloride, sodium dodecyl sulfate and infiltration powder agent; the raw material is measured according to the proportion, and the powder explosive can be made after the processes of additives mixing, grinding and drying, saltpeter mixed oil pressing, mixed material cooling and explosive packing. The invention is mainly suitable for the continuous automatic production of the non-TNT powder ANFO explosive; whether in a discontinuous production or a continuous production, the compound additive and preparation process of the invention can be adopted to lower the temperature and save energy with environmental protection and safety, furthermore, the product comprising water-resistant explosive has a stronger moisture absorption resistant & water resistant performance, explosion performance and storage performance.
