Abstract
The smokeless gun propellant for fireworks consists of retired gunpowder 70-90 wt%, oxidant 5-10 wt% and inflammable 1-5 wt%. The oxidant is nitrate, chlorate or perchlorate; and the inflammable is carbon powder, aluminum powder, magnesium powder or aluminum-magnesium alloy powder. The preparation process includes crushing, dewatering, mixing, dispelling water and drying. The smokeless gun propellant is used in ground fireworks product to replace black powder as propellant agent, and this can reduce smoke produced during firing fireworks greatly, reduce dust pollution to environment and lower production cost. The present invention paves one way of utilizing retired gun powder resource in large scale.
Description
Technical field
The present invention relates to the emission medicament that a kind of fireworks are used.
The invention still further relates to the preparation method of above-mentioned emission medicament.
Background technology
The processing of military useless gunpowder is a hard nut to crack.Also really do not find at present recycling approach practical, the energy mass disposal in the world.Therefore, still have at present handle this class refuse in the destruction mode.China's " 866 engineering " has worked out many effective resource utilization approach, as prepare with useless medicine industrial explosive, with useless medicine prepare the nailing small arms propellant, the medicine that will give up is used for the oil fracturing bullet, with waste single base propellant system oxalic acid or the like.Utilize in the approach at these, except that the system industrial explosive, the characteristics of other method are the added value of product height, even very high, but treatment capacity is very limited.Preparing the industrial explosive technology with useless medicine implements in 245 factories and Laizhou, Shandong explosive factory.This technology possesses the ability of the useless medicine of extensive processing, but because existing ammonium nitrate dynamite and water-bearing explosive price have been quite cheap, the explosive user has been accustomed to using common industrial explosive, and this is in today of market economy, it is bigger to promote difficulty, unless lower with the industrial explosive price of useless gunpowder preparation.Just because of this, the gunpowder that China scraps in the national treasury, the particularly useless gunpowder of some ordnance repairman shop of military bomb disposal gained are still destroyed in burning in large quantity.Therefore useless gunpowder recycling new technology, the product innovation of mass disposal ability satisfied the need, possesses in developing target market, still has important practical significance.
On the other hand, in the fireworks display class fireworks of ground, use a kind of black powder (being commonly called as military project nitre) to make propelling charge usually at present.When setting off, black powder is in the weapon barrel internal combustion, and the pressure of generation is aerial with effect cartridge case directive, and breaks out confession people such as various pearl head-ornaments, banger, sibilant rale or the thing that waves and view and admire.In these class fireworks, people are accustomed to using the black powder energy that is used as power, and have formed traditional manufacturing technology, and the product firework display effect is better.But during owing to the black powder burning, generate minuteness particle, formed smog, cause dust pollution.Along with the raising of people's living standard and the continuous enhancing of environmental consciousness, the requirement of fireworks smokelessly not being had environmental protection indexs such as residue and production process security is also more and more stronger, smokelessly, the environment-friendly type fireworks medicament of safety has become the direction that fireworks industry research person pursued and the developing direction of fireworks industry, but has not also searched out the emission medicament of smoke-less up to now.
Summary of the invention
The object of the present invention is to provide the smokeless propellant agent of a kind of fireworks.
Another object of the present invention is to provide the preparation method of above-mentioned emission medicament.
Smokeless propellant agent provided by the invention is in the fireworks display class fireworks of ground, and the replacing whole black powder energy that is used as power reaches the smog growing amount when significantly reducing firework display, reduces the dust pollution to environment, reduces cost of manufacture.Open up the new way of an extensive recycling Containing Waste Propellant of energy simultaneously.
For achieving the above object, smokeless propellant agent provided by the invention, it consists of:
The Containing Waste Propellant powder: its mass percent is 70-90%.
Oxygenant: its mass percent is 5-20%; The effect of this oxygenant is to provide necessary oxygen for combustible object in sending out the medicament combustion processes.
Combustiblematerials: its mass percent is 1-10%; The effect of this combustiblematerials provides the combustiblesubstance in the emission medicament combustion processes, and its burning is normally carried out.
Above-mentioned Containing Waste Propellant powder comprises single, double basic medicine, and its granularity is below 40 orders.
Above-mentioned oxygenant is nitrate, oxymuriate and perchlorate.Furtherly, with NH
4ClO
4, KNO
3, Sr (NO

3Deng more suitable.
Above-mentioned combustiblematerials is more suitable with carbon dust, aluminium powder, magnesium powder or aluminium-magnesium alloy powder etc.The combustiblematerials powder size is the same with the granularity requirements of Containing Waste Propellant
The method of the above-mentioned smokeless propellant agent of preparation provided by the invention is:
1) being starting raw material with useless medicine, carrying out pre-treatment earlier, mainly is to reject the end of a thread of sneaking in the useless medicine, waste paper, metallic impurity etc.;
2) pulverize: be soaked in the 4-8 water doubly with useless medicine, be ground into powdery, sieve, obtain the medicinal powder of designated size;
3) dehydration: with the medicinal powder that screening obtains, be loaded in the water-permeable bag, centrifuge dehydration, dewatering time is decided according to the amount of medicinal powder, and generally taking off does not have the water outflow to get final product, and obtains aqueous medicinal powder, and its water content is about 15-25%; Used water-permeable bag can be the sack that textiles is made, as cotton or fibers material etc.;
4) mix: fire powder, oxygenant, combustiblematerials are mixed in proportion;
5) expelling water: adopt the method for seasoning to make moisture content be reduced to 9～14% mixed gunpowder thing, thereby obtain smokeless medicament with water.
6) the smokeless medicament of band water that makes is dried before use and is made its water content be lower than 5%.The general method that adopts nature airing or drying room oven dry of oven dry.The condition of drying room oven dry is: 50 ℃ of temperature, and dry and got final product in 48 hours.
This medicament energy replace black gunpowder uses in spraying decoration and ground fireworks display class fireworks and is based on following principle: smokeless medicament is made by single base or double-base propellant, it is the same with black powder to belong to together and self contains oxygen and contain fuel material, can burn in oxygen-free atmosphere, they all rely on the external work done of high-temperature gas that the burning back generates.
