Technical Field

The invention relates to the field of civil and military dual-purpose firer, in particular to a high-energy high-combustion-rate ignition medicament.

Background

In the current special battle and urban anti-terrorism battle, the fighter can meet the conditions that gates, windows and the like need to be broken through, and the fighter often uses grenades, heavy hammers and the like to break through violence under the conditions, but the noise is too large, fragments are generated, and the efficiency is low and unsafe.

An ideal medicament for solving the problems is required to be carried about, and can fuse a steel bar, burn through a steel plate, a lock cylinder and the like only by about 10 seconds, so that the medicament has the advantages of concentrated energy, large flame power, positive flame output and capability of ensuring the safety of operators; light weight, convenient carrying, low cost and suitability for large-scale production. However, the existing similar ignition agents are often high in cost, or low in burning speed and energy, and cannot meet the requirements. Therefore, the development of an ignition agent with high energy, high burning rate and low cost is urgent.

Disclosure of Invention

The invention aims to provide an ignition agent with high energy, high burning rate and low cost aiming at the problems of high cost, low burning rate, low energy and the like of ignition powder in the current industry so as to solve the problems.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a high-energy high-combustion-rate ignition medicament comprises the following components in parts by weight:

as the oxidizing agent: 9-13 parts of potassium perchlorate

47-53 parts of ferric oxide

3-7 parts of copper oxide

As reducing agents: 25-30 parts of aluminum powder

1-5 parts of nickel powder

Adhesive: 4 to 6 portions of

Mixing the above materials, and granulating.

The ignition medicament generates high-temperature liquid metal and a large amount of gas during combustion, generates high-temperature and high-pressure gas and liquid metal in a narrow space, is ejected out of the throat of a product to form high-temperature metal jet flow, acts on a target, and is quickly fused and melted through the target. The adhesive of the present invention may be a fluororubber or the like.

Wherein the reaction for producing the liquid metal is as follows:

Fe₂O₃+CuO+2Al+Ni＝Fe+Cu+Al₂O₃+NiO

because the reaction has almost no gas product, potassium perchlorate is added in the formula for generating a large amount of gas, and the reaction mechanism is as follows:

firstly, potassium perchlorate is decomposed by heating KClO₄＝KCl+2O₂×) and part of oxygen participates in the reaction, and the rest gas is used for high pressure of the product to form jet flow.

The granulation method can be that after the components are mixed uniformly, the mixture is granulated by using a copper sieve, and the sieve mesh of the copper sieve can be 35-50 meshes, preferably 40 meshes.

As a preferred technical scheme: the raw material grades are all analytically pure.

As a preferred technical scheme: the granularity of the potassium perchlorate, the copper oxide and the nickel powder is 200 meshes of standard screen underflow.

As a preferred technical scheme: the particle size of the ferric oxide and the aluminum powder is 100 meshes of standard screen underflow.

As a preferred technical scheme: the solvent of the adhesive is acetone. The solvent of the adhesive can be part of other organic solvents, but acetone has the lowest cost, the lowest toxicity and is volatile, the acetone is naturally dried after the ignition agent is granulated, the acetone is volatilized, and then the acetone is dried in a safe oven. Preferred as the binder dissolving agent.

As a preferred technical scheme: the free bulk density of the granulated ignition agent is 0.9-1.1 g-cm^-3。

The ignition medicament is pressed into the hollow charge. The size of the drug column is

The hollow part has the size of

The size can be adjusted according to the actual situation, and the adjustment principle is that the ratio of the maximum outer diameter to the height of the explosive column is close to 1:1, so that the error of the density of the pressed explosive on the upper surface and the lower surface of the explosive column is minimum under the condition of ensuring the maximum efficiency in the pressing of the explosive column; the diameter of the central hole is the best scheme obtained according to the experimental condition, and the central hole is used for improving the combustion stability of the explosive column and controlling the combustion speed of the explosive column.

The pressing density is 2.0-2.2 g/cm³。

The scheme is preferably as follows: when the medicament is granulated, the granulation is carried out before the wet mixed medicament is completely dried. Because of the particularity of the adhesive, the medicament cannot be sieved under the condition of high humidity, and the medicament can be stuck on a drying net and cannot be granulated. If the medicament is completely dried, the medicament becomes too hard and hard to be granulated through a screen.

Assembling into a longitudinal fire rod, preferably dividing the hollow grain into 3 parts for pressing to ensure the density uniformity of the grain, wherein the height of the single-shot grain is 30mm, and the pressed density is (2.0-2.1) g.cm³。

The dry mixing of the medicament is to sieve and mix the oxidant and the adhesive evenly, then add the dissolved adhesive, and the dry mixing is sieved for 6 times continuously, so that the two components are mixed evenly, when mixing the medicament by hand, the medicament with the weight of less than 1 kg can be mixed evenly by sieving for 3 times, and the medicament with the weight of 3-5 kg needs to be sieved for more than 5 times when sieving. The 100 mesh sieve is used because the drug raw material particles are all over 150 mesh, and the smaller the diameter of the sieve used, the more sufficient the mixing becomes. Sieving is a better process in the manual medicine mixing process. Compared with a three-dimensional medicine mixing machine and a planetary ball mill, dead corners and large vibration of medicine mixing can not occur in manual sieving.

Compared with the prior art, the invention has the advantages that: the high-energy high-combustion-rate ignition medicament is pressed into a hollow solid grain during use and assembled in an ignition weapon. The ignition medicine box is ignited through the medicine head in the medicine box, the medicine head is ignited through the controller in the handle, the controller in the handle controls the power supply to supply electricity, the ignition medicine head in the medicine box is ignited, the medicine in the medicine box is ignited after the medicine head is ignited, the medicine is ignited to ignite the medicine column, the medicine is ignited to burn the medicine rapidly, a large amount of high-temperature gas and metal jet flow are generated to act on the targets such as a door and a window, the target can be fused within 10s, and the ignition medicine box can normally work under the environment of minus 45 ℃ to 55 ℃ and the vibration environment.
