废弃动植物油脂制备膨化硝铵炸药研究

Study on Preparation of Expanded Ammonium Nitrate Explosives From Waste Vegetable Oils and Animal Fats

研究了以废弃动植物油脂为原料制备膨化硝铵炸药,调节出的膨化硝铵炸药生物复合油,具有同膨化硝铵炸药复合燃料油相近的物理性能:针入度(0.1mm)71.3,运动黏度5.51mm2/s,滴熔点55.3℃。用其所制备的膨化硝铵炸药的爆速为3350m/s,殉爆距离为6cm,猛度为14.1 mm,此爆炸性能符合《WJ9026-2004膨化硝铵炸药》的要求,且具有低成本、合适的理化性能,能够满足膨化炸药爆炸性能的同时,使我国问题繁多的"地沟油"得到了资源化利用,具有良好的经济及社会效益,变废弃油脂作为理想的可燃剂。

In this paper, we studied the feasibility of preparing special bio-composite oil from waste animal and vege- table oil for expanded ammonium nitrate explosive. By improving the formulation, ammonium nitrate explosive bio- composite oil that had similar drop melting point （0. lmm） 71.3, penetration 5.51 mm^2 /s, kinematic viscosity 55. 3℃ with expanded arnmonium nitrate explosive fuel oil compound can be prepared. The performance of expanded ammonium nitrate explosive prepared from the bio-composite oil could accord with requirements of WJ9026-2004 Expanded Ammonium Nitrate Explosive. The performance of expanded ammonium nitrate explosives could be satisfied by low cost, appropriate physical and chemical properties, meanwhile, the problem of ＂gutter oil＂ could be solved and we could make them reused. So the bio-composite oil could be used as an ideal flammable agent for expanded ammonium nitrate explosive.
