Abstract

The invention discloses a method for producing an explosive insensitive wax. According to the method, on the basis of a common sweating technology, air flow is utilized to carry liquid oil by a wax layer so as to forcefully separate the wax from the oil in a sweating process, and meanwhile, optimally, the raw material wax and aqueous solutions of more than two matters capable of reacting and generating gas are respectively emulsified and then sweated and the quick emission of the oil is benefited, so that an explosive insensitive wax product with low oil content can be produced according to a sweating de-oiling method. The method disclosed by the invention has the advantages of low equipment investment, simple preparation process, low operation cost, safety, energy-saving effect, no solvent pollution, and the like.

Description

technical field [0001] The invention belongs to the technical field of special wax production, in particular to a method for producing explosive insensitive wax. Background technique [0002] Explosives are substances that can burn or decompose quickly. Under the action of certain external energy, they can burn violently (that is, explode) in a very short period of time to generate a large amount of heat and gas, and perform stable detonation work on the outside world. Currently commonly used explosives are TNT, high-energy explosives RDX (RDX, cyclotrimethylammonium trinitrate) and Octojin (HMX, cyclotetramethylenetetranitramine) and so on. [0003] Under certain conditions, the various sensitivities of explosives are closely related to the safety of the charge. The lower the various sensitivities within a certain range, the better the safety of use. Depending on the detonation impulse sensitivity, it can be expressed as: thermal sensitivity, flame sensitivity, mechanical ...
