Abstract
The invention relates to a powdery explosive prepared from waste single-base explosive, which aims to solve the problems of high cost, high mechanical sensitivity and low utilization rate of waste explosive. The composite desensitizer is adopted to reduce the cost and sensitivity and improve the utilization rate of the waste single-base medicines, and comprises the following components in percentage by mass: 65-92 parts of waste single base, 5-30 parts of ammonium nitrate, 1-10 parts of water and 2-8 parts of composite desensitizer. The invention is mainly used for engineering blasting and seismic source explosive loading.
Description
The present invention is a kind of powder type explosive with the waste single base propellant preparation, relates to industrial explosive, is mainly used in engineering explosion, hypocentrum cartridge powder charge.This explosive is made up of waste single base propellant, ammonium nitrate, water and deterrent.
Along with the development of weapons technology, the update of cannon and relevant ammunition thereof is inevitable, and correspondingly a large amount of propelling charge also will " retire from active service ".How are these propelling charge of scrapping handled? be to be related to the big problem that system is stocked in national ammunition production.
The main for a long time method that adopts burning to destroy is handled useless propelling charge.This method not only will expend huge human and material resources, financial resources but also cause environmental pollution, even the casualty accident that may meet accident.
Utilized at present useless propelling charge exploitation to make the slurry explosive that has a water resisting property, but the useless propelling charge that contains in the slurry explosive only accounts for 20%～40%, useless propelling charge utilization ratio is lower.The propelling charge that will give up that has pours among the fused TNT, makes pyrotechnic composition.But because of TNT source is nervous, price is high, thereby the cost height of pyrotechnic composition, and TNT toxicity is big, has influenced and has promoted the use of.Chinese patent 95111083.7 has been reported " a kind of powder type explosive and manufacture method thereof ", and it comprises useless medicine, ammonium nitrate, water and deterrent, has overcome the deficiency of secure context in prior art production, the storage process.Be characterized in that technology is simple, useless medicine utilization ratio increases, but a large amount of deterrent graphite that uses improves cost greatly, and the insensitiveness effect is low, and mechanical sensitivity is higher.
The objective of the invention is in order to overcome disadvantages of background technology, designed a kind of waste single base propellant utilization ratio height, technology is simple, with low cost and mechanical sensitivity is low powder type explosive.
Design of the present invention: to achieve these goals, adopt cheap paraffin to replace graphite, but paraffin can not directly add at normal temperatures.Paraffin becomes blocks of solid at normal temperatures, does not still have feasible method at present it is crushed to enough tiny granularity, and make it " coating " equably single-base powder powder; Though adopt heating means can make melted paraffin wax become liquid, fused wax liquid can not play effective coating insensitive action to moisture 10%～30% single-base powder powder.And the single-base powder powder is carried out drying treatment is very dangerous thing.In order to solve this technical barrier, come emulsified olefin with tensio-active agent, make a kind of compound deterrent, because tensio-active agent improves the dispersiveness of wax, make wax can evenly be coated on single-base powder powder surface, greatly reduce the mechanical sensitivity of spice, thereby guaranteed the security of Operating Condition of Powder Explosive Production, use, reduced production cost again.
The present invention is a kind of powder type explosive with the waste single base propellant preparation, is characterized in containing the compound deterrent of tensio-active agent, and its quality percentage composition is as follows:
Waste single base propellant 65～92
Ammonium nitrate 5～30
Water 1～10
Compound deterrent 2～8
The percentage composition of wherein compound deterrent quality is as follows:
Paraffin 45～75
Tensio-active agent 10～15
Binding agent 10～45
Quality percentage composition of the present invention is as follows:

Advantage of the present invention is as follows:
1. compound deterrent can carry out effective insensitiveness to aqueous single-base powder powder at normal temperatures to be handled;
2. compound deterrent is with low cost, and the insensitiveness effect is remarkable;
3. powder type explosive of the present invention is easy to be pressed into powder column, and as the hypocentrum cartridge powder charge, explosion velocity is up to 6100m/s;
4. single-base powder adopts a disintegrating process, has both improved production efficiency, has ensured personnel safety again better;
5. single-base powder powder utilization ratio is higher, in addition not oxidizer and make functional, can be fit to produce the powder type explosive of use.
