Description
Technical field
The present invention relates to a kind of composite explosives and preparation method thereof, particularly a kind of heat resistance composite explosives and its making
Method, belongs to engineering material field.
Background technology
The appearance of heat-resistant explosive, meets the extraordinary needs of space travel, oil deep-well perforation powder charge.At present, it is domestic main
Use with RDX (RDX), HMX (HMX) is the heat-resisting composite explosives of base, although explosion energy is higher, but heat-resisting
Performance is not ideal enough；With 2,6- dipicrylamine base -3,5- nitropyridines (PYX), the heat-resisting composite explosives that hexanitro Stilbene (HNS) is base
There is excellent heat resistance at 210-260 DEG C, but explosion energy can not fully meet use requirement, and also it is expensive.
1887, Jackson and Wing synthesized this heat-resistant explosives of TATB first, and it not only has good heat resistance, and
There are higher explosion energy, but selling at exorbitant prices, it is too high for the production cost of the industries such as petroleum perforation equipment.Therefore, one is developed
Plant high-energy, inexpensive heat resistance composite explosives imperative.
With the fast development of industry, shallow well and middle-deep well petroleum resources are petered out, domestic and international oil exploitation industry
Gradually by the shallow well or middle-deep well in inland, upcountry deep-well, ultradeep well and ocean deep-well develop.Oil field deep well and ultradeep well are opened
Adopt increasing for quantity, heat resisting temperature is 200 DEG C or so and can not met by the composite explosives of base of RDX base and HMX
It is required that, it is necessary to the higher heat-resistant explosive of heat resisting temperature.To the increasing of high-temperature heat-resistance explosive demand, cause scientific worker
The attention studied high-temperature heat-resistance explosive, achieves some achievements in research in terms of high-temperature heat-resistance explosive.
In recent years, polyamino polynitropyridine and its nitrogen oxides are obtained extensive concern by domestic and international, wherein 2,6- diaminos
The structure of base -3,5- di nitryl pyridine -1- oxides (ANPyO) is similar to TATB, is that a kind of heat-resisting simple substance of function admirable is fried
Medicine,, can conduct to some hot environments and the occasion of specific use with higher explosion energy and good thermostability
TATB substitute, the heat-resisting composite explosives that existing PYX, HNS are base can also be substituted by being prepared into heat-resisting composite explosives.
Goal of the invention
The purpose of the present invention is to provide high-energy, the heat-resisting composite explosives of low cost always first；
It is another object of the present invention to produce the method for this safe and reliable heat-resisting composite explosives, and prepare following business
The application that product is made of demand in industry：
Heat-resisting composite explosives are used as single powder charge；
By this heat-resisting composite explosives and petroleum perforation charge housing combination.
