Wang Wanyong (Wang Wanyong. Experimental Research on Improving the Water Resistance and Fluidity of Rock Expanded Ammonium Nitrate Explosives[J]. Coal Mine Blasting, 2015(3):13-15) Aiming at the poor water resistance and fluidity of rock expanded ammonium nitrate explosives in the existing continuous production line In order to improve the water resistance and fluidity of rock puffed ammonium nitrate explosives, it is proposed to improve the water resistance and fluidity of rock expanded ammonium nitrate explosives through double modification technology, that is, to improve the composite oil phase and wood powder, while ensuring that the performance of the explosives is not affected

Abstract

The invention provides an explosive modification composition and its preparation method and application, which belong to the technical field of explosives. An explosive modification composition prepared from the following raw materials in parts by weight: 15-25 parts of octadecyl primary amine, 60-80 parts of phosphoric acid, 5-15 parts of stearate, 0-3 parts of coloring agent parts, 0~3 parts of auxiliary materials. The explosive modification composition of the present invention is used in the rock expanded ammonium nitrate explosive, which can improve the fluidity of the rock expanded ammonium nitrate explosive, adjust the charge density, increase the power of the explosive, and improve the safety performance and storage performance of the explosive.

Description

technical field [0001] The invention belongs to the technical field of explosives, and in particular relates to a modified explosive composition, a preparation method and application thereof. Background technique [0002] Expanded explosive is a new type of ammonium nitrate explosive developed in the 1990s. Its biggest feature is that it does not contain TNT, but its power is equivalent to that of ammonium nitrate explosives containing TNT, while reducing environmental pollution. The preparation of puffed explosives is to first make a puffing agent from a surfactant, a foaming agent, a water enhancer and an ammonium nitrate crystal phase stabilizer; into microporous ammonium nitrate; finally, expanded ammonium nitrate, fuel oil, wood powder (expanded explosives used in coal mines also need to be added with salt) are mixed to make expanded explosives. [0003] Ammonium nitrate itself is a strong polar inorganic salt that is easily soluble in water. It can strongly absorb wa...
