Powdery emulsion explosive

Abstract

The invention relates to a powdery emulsion explosive, which is prepared by the following steps: taking the raw materials of 75-85% of ammonium nitrate, 5-10% of auxiliary oxidant, 2-6% of organic oil-phase material, 0.7-1.3% of emulsifier, 1-3% of cosolvent, 1-11% of blast reducer and 1-5% of water by weight, wherein the organic oil-phase material takes decompressing cerate, petroleum wax, foots oil and polymer as basic raw materials in current technology, supplementing a phospholipid additive, introducing air under the conditions of temperature of 140-180 DEG C and an 0.1%-1.0% oxidation catalyst, and reacting for 2-10 hours. The present invention improves explosive performance, water resistance, moisture resistance, caking resistance and storage stability of the powdery emulsion explosive, and reduces the usage amount of emulsifier. The powdery emulsion explosive is subjected to industrial production under any environment, and completely eliminates harm of TNT on human and environment.

Description

technical field [0001] The present invention relates to a powdery emulsion explosive. Background technique [0002] Powdered emulsion explosive is a new type of civil blasting explosive with international advanced level invented in the late 1990s. Dried powdered explosives. It not only has the excellent water resistance of emulsion explosives, the components do not contain TNT, and does not have any harm to the environment and human body, which conforms to the development trend of non-ladder-free civil explosives, and has the solid state characteristics of powdered ammonium-ladder explosives. It has the advantages of stability, high explosive force (working force), and flexible and convenient use. Powdered emulsion explosives overcome both the poor stability of emulsion explosives and the shortcomings of poor water resistance of powdered explosives. [0003] Powdered emulsion explosives are very different from emulsion explosives and powdered explosives from formula to pr...

Problems solved by technology

However, succinimide polymer emulsifiers are easy to decompose at high temperatures to generate nitrogen and carbon dioxide, which reduces the emulsification efficiency, and makes the emulsification matrix contain a certain amount of gas, reducing the density of the emulsification matrix, so that the emulsification matrix has a certain Detonation Sensitivity Affects the Safe Production of Powdered Emulsion Explosives

In addition, these patents all use petroleum refined products as the basic raw materials of the oil phase, so that the oil / wax is separated in the petroleum processing process and made into corresponding paraffin, ozokerite, lubricating oil and other commercially available petroleum products and then re-blended, resulting in unnecessary manpower , material and energy waste
