Problems solved by technology

[0003] Although the expanded explosive produced by this process is mixed in the excimer state, the ammonium nitrate and the oil phase material can be fully mixed and contacted, and the explosive performance and water resistance of the explosive are greatly improved compared with the intermittent traditional process, but due to the expansion of ammonium nitrate After the surface area increases sharply, the oil phase material still cannot directly cover the expanded ammonium nitrate completely, so the production of this process still cannot really solve the water resistance problem of expanded explosives, and the expanded explosives produced by this process still cannot be directly used in water-filled operations surface, which brings a lot of inconvenience and restrictions to the use of expanded explosives in the water working surface

Abstract

The invention discloses a water-resistant composite oil phase specially used in the production process of liquid-mixed expanded explosives, using decompression wax paste, tar, fatty acid, surface treatment agent, paraffin and anti-caking agent as raw materials in separate melting tanks Internally heat up and melt, and then pump each material into the reaction kettle after being measured by the oil pump and electronic scale according to the ratio requirements, and then raise the temperature to 100-110°C and keep the uniform stirring state in the reaction kettle, and turn on the vacuum pump at the same time to evacuate the reaction kettle Dehydration and filtration are carried out in sequence, and the filtered material is formed and packaged to obtain the water-resistant composite oil phase product. The puffed explosive produced by the composite oil phase of the present invention has good explosive performance, and its biggest advantage is that the puffed explosive has excellent water resistance, and the bulk puffed explosive can be insoluble in water for several hours to tens of hours when sprinkled on the water surface.

Description

technical field [0001] The invention relates to the field of industrial explosives, in particular to a water-resistant composite oil phase specially used in the production process of liquid-mixed puffed explosives. Background technique [0002] The liquid mixed expanded ammonium nitrate explosive production process adopts the technology of mixing first and then expanding, and the explosive formula is designed on the principle of zero oxygen balance. The principle of its preparation is to mix the oxidant ammonium nitrate and the oil phase of the combustible agent in a liquid excimer state by using its own turbulent flow, mixer and pumping mixing in the delivery pipeline to form an oil-in-water dispersion system, and then in the The finished product is obtained by drying in a vacuum state to remove water and puffing. This process truly realizes the continuity of the puffing and mixing process. Compared with the original discontinuous puffing process, the explosive performance...
