本文研究了一种用于乳化炸药的专用复合脂,是以废弃动植物油脂(地沟油及煎炸老油)为主要原料,经过一定的物理工艺处理,辅之以高热值并具有催化活性的材料对其改性制备而得。其物理性能指标为：针入度(0.1 mm)58,运动黏度7.38 mm2/s,含油量(质量分数)30.2％,滴熔点56℃,用其制备的乳化炸药的爆速为4980 m/s,殉爆距离为5 cm,猛度为18.5 mm,且成本低、理化性能合适,能够满足乳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。%[ ABSTRACT] In this paper, a special compound wax used for emulsion explosive was studied. It mainly consists of abandoned animal and vegetable oil ( waste oils and fried oil) , and was prepared by a certain physical process and modified by materials with high calorific value and high catalytic activity. Its physical properties are as follows:the penetration (0. 1 mm) is 58, the kinematic viscosity is 7. 38 mm2/s, the mass fraction of oil is 30. 2% and the drop melting point is 56℃. Detonation performances of the emulsion explosive prepared by the special compound wax are as follows: the detonation velocity is 4 980 m/s, the gap distance is 5 cm and the brisance is 18. 5 mm. The special compound wax has the advanta￣ges of low cost and appropriate physical and chemical properties, and it enables to meet the detonation performances of emulsion explosives, which not only effectively utilize waste oil with a wide range of problems but also has numerous economic and social benefits.
