Abstract

The invention discloses a density moderating agent for powdery explosives for explosive cladding. The density moderating agent is prepared from one or more mutual compounds in parts by weight: 500 to950 parts of perlite, 10 to 400 parts of carbon powder, 50 to 300 parts of aluminum powder and 30 to 200 parts of talcum powder. Raw materials selected by the density moderating agent are hydrophobicsubstances, so that free-flowing property of the explosives can be effectively improved and humidity resistance performance of the explosives is greatly improved. The invention also discloses a preparation method of the density moderating agent for the powdery explosives for explosive cladding. The method comprises the following steps: putting one or more of the perlite, the carbon powder, the aluminum powder and the talcum powder into a mixing machine; turning on the mixing machine and performing mixing for 30 to 60 minutes to obtain a mixture, and then packaging the mixture into a bag. A technological method of the density moderating agent is simple; the density conditioning agent prepared by adopting the method is stable in quality, and can be used for modifying density and detonation velocity of ammonium nitrate fuel oil explosives and multi-pore-particle ammonium nitrate fuel oil explosives and regulating free-flowing property.

Description

technical field [0001] The invention belongs to the field of metal composite material production technology, and relates to a powdery explosive for explosive compounding, in particular to a powdery explosive density regulator for explosive compounding, and to a preparation method for the powdery explosive density regulator for explosive compounding.
