Description

technical field [0001] The invention belongs to the field of functional chemicals, and in particular relates to a surfactant for porous granular ammonium oil explosives, a performance enhancer for porous granular ammonium oil explosives, a preparation method thereof, and a porous granular ammonium oil explosive. Background technique [0002] Porous granular ammonium oil explosive, referred to as ANFO, is a common on-site mixed explosive. It is prepared by physically mixing porous granular ammonium nitrate and oil phase. It has the advantages of simple production process, low cost and high cost performance. ANFO is a typical heterogeneous mixed explosive. The porous granular ammonium nitrate used is a substance with high porosity and high specific surface area, and the specific surface area can be as high as 1000cm 2 g -1 , usually, in order to meet the "zero oxygen balance" of the oxidizing agent and the reducing agent required for the explosion, the more suitable weight ra...
