Abstract

The invention discloses a hectogram-grade Mn-BTO energy-containing coordination polymer and a preparation method thereof. The preparation method comprises the following steps: adding an aqueous solution of an inorganic metal manganese salt into an aqueous solution of 5,5'-bistetrazolyl-1,1'-dioxygenyl salt drop by drop under stirring, wherein the mole ratios of the both aqueous solutions are equal; then continuing isothermal stirring for 1 h, carrying out cooling to room temperature after completion of a reaction; and carrying out pumping filtration and drying so as to obtain Mn-BTO crystal powder. The preparation method is simple in process flow, convenient to operate, mild in reaction conditions, good in security and capable of preparing the hectogram-grade product; and the hectogram-grade Mn-BTO energy-containing coordination polymer prepared by using the method has good safety performance, high quality, small crystal grain size and uniform particle size distribution, and is applicable as a component for an explosive, gunpowder and a propellant.

Description

technical field [0001] The invention relates to the field of energetic materials, in particular to a hundred-gram-level Mn-BTO energetic coordination polymer and a preparation method thereof. Background technique [0002] Energetic complexes are a kind of complexes with strong explosive function. Due to their special energy properties, they have been used in the field of primary explosives decades ago. Compared with ordinary energetic complexes, energetic coordination polymers have higher energy density and crystal order, and their structures can be expressed in one-dimensional, two-dimensional or three-dimensional forms in space, and the high degree of ordered structure The dimensional structure determines the ideal physical properties (high density and good mechanical properties) and stable chemical properties (good thermal stability, high energy output and low sensitivity) of these materials, which may provide new opportunities for the development of new energetic materia...
