Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a desensitizing performance of not igniting even if a current of 1 watt / ampere for 5 minutes is applied as current sensitivity, and has an operating time of 1 millisecond (m).
s), which is within the range of s).

[0002]

2. Description of the Related Art In order to prevent accidental ignition due to stray current, static electricity, electromagnetic waves, etc., an insensitive ignition device has, for example, a current sensitivity of insensitive type that does not ignite even if a current is applied for 5 minutes at 1 watt and 1 ampere. Performance is required. As the ignition charge for this insensitive ignition device, a two-component ignition charge of potassium zirconium perchlorate has been generally used conventionally.

As a desensitizing method, a method of attaining on the ignition charge side by consolidating or holding the ignition charge mixed with a binder such as synthetic resin or synthetic rubber at a high density, or changing the material of the electric bridge Alternatively, a method of achieving desensitization on the bridge side by increasing the wire diameter and increasing the heat dissipation area is known. On the other hand, in order to control the flight direction of an ultra-high-speed flying body, research and development of an impulse thruster that is mounted on a large number of flying bodies and changes the velocity vector by ejecting in the lateral direction has been advanced recently in various countries. The impulse thruster ignition device is required to be electrically insensitive and have a short operating time.

[0004]

However, the conventional insensitive ignition device tends to desensitize the current sensitivity and tends to extend the operating time, and when used as an ignition device for an impulse thruster which operates in an extremely short time. It is necessary to ignite within at least 1 millisecond (ms), and it has been impossible to achieve the operation time with the conventional insensitive ignition device.
In other words, desensitization of current sensitivity and shortening of operation time were in conflict with each other.

Therefore, there has been a demand for the development of an ignition device which has insensitive performance and operates at a high speed with an operating time of 1 millisecond (ms) or less.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to have insensitive performance that does not ignite even when a current is applied for 1 watt and 1 amp for 5 minutes, and has an operating time of 1 millisecond (m).
s) to provide a fast-acting ignition device. As a result of intensive studies, the present inventors have found that the above problems can be solved by selecting a certain ignition composition.

That is, the present invention is an ignition device comprising a plug with a bridge, a bottomed cup as an ignition charge enclosing member, and an ignition charge filled in the bottomed cup, wherein the ignition charge is zirconium and pigmental aluminum. It is an insensitive high speed actuation igniter characterized by comprising potassium perchlorate. Next, the present invention will be described more specifically with reference to the drawings.

The insensitive high speed operation ignition device according to the present invention is
As shown in FIG. 1, the leg wire 3 and the core wires 4a and 4b pass through the embolus body 1 having the bottomed cup fitting portion 2, and the core wire 4a,
A bridge 5 is joined to the end of 4b. Bottomed cup 6
Is fitted into the bottomed cup fitting portion 2 of the embolus body 1, and the inside of the bottomed cup 6 is filled with the ignition charge 7.

When the insensitive high-speed actuation ignition device of the present invention is used as an impulse thruster ignition device, as shown in FIG. 2, a container 8 filled with a high-pressure gas generating agent 10 is shown in FIG. An igniter is attached, and a nozzle 11 is attached to this tip. For the embolus body 1 and the bottomed cup 6, it is preferable to use a thermoplastic resin such as polyethylene, polypropylene, polyvinyl chloride, polyurethane or polyester.

What is important in the present invention is that the ignition charge 7 filled in the bottomed cup 6 is composed of zirconium, pigmental aluminum and potassium perchlorate. The content of zirconium is usually 20 to 55% by weight.
And particularly preferably 33 to 47% by weight. Pigmental aluminum is a fine particle aluminum pigment produced by crushing an aluminum ingot while covering it with a thin layer of fats and oils such as stearic acid and oleic acid, and the compounding amount is usually 20 to 5% by weight. It is preferably 12 to 8% by weight. When the amount of the pigmental aluminum compounded is more than 20% by weight, the maximum non-ignition current value increases and becomes good, but the ignition time becomes late. On the other hand, if the amount is less than 5% by weight, the ignition time will be shortened, but the maximum non-ignition current value will decrease, and desensitization cannot be achieved.

The amount of potassium perchlorate is usually 60 to
It is 40% by weight, and particularly preferably 55 to 45% by weight.
Here, the pressing pressure when filling the bottomed cup 6 with the ignition charge of the present invention is usually 50 kg / cm 2 or more, particularly 150 kg.
It is preferable to fill at a rate of not less than / cm 2 . Filling pressure is 50
When it is less than kg / cm 2 , both the maximum non-ignition current value and the ignition time decrease.

In addition to the above-mentioned three essential components, a fluorinated resin, a silicone adhesive or the like can be added to the ignition charge of the present invention as a binder, if necessary. As the high-pressure gas generating agent 10, for example, one containing boron-ammonium perchlorate, boron-potassium nitrate, ammonium perchlorate-terminated hydroxyl group polybutadiene as a main component is used.

The plug with a bridge of the present invention, the bottomed cup 6 as the ignition charge enclosing member, and the ignition charge 7 filled in the bottomed cup 6.
In the igniter consisting of the following, by using the insensitive type fast-acting igniter characterized in that the igniting charge 7 consists of zirconium, pigmental aluminum and potassium perchlorate, a current is applied for 1 watt and 1 amp for 5 minutes. The insensitive type performance that does not ignite even if it is, and the operating time is within 1 millisecond (ms), the performance of high speed operation can be satisfied,
It can also be used as an ignition device for impulse thrusters.

Examples 1 to 4 Zirconium (Zr) according to the present invention and pigmental aluminum (PA) were used for the embolus body with leg wire 1 and the bottomed cup 6 injection-molded using polyester resin.
1) and igniting charge composed of potassium perchlorate (KClO 4 ) were blended at the blending ratio shown in Table 1 and filled at the press pressure shown in Table 1. The ignition device thus obtained was measured by the optical fiber method for the maximum current value that did not ignite when a direct current was applied for 5 minutes and the ignition time when a current of 7 ampere (A) was applied, and the results were obtained. The results are shown in Table 1.

As is clear from the results shown in Table 1, the insensitive type high speed actuation ignition device of the present invention can achieve either insensitive performance or high speed operation except for the ignition charge of the present invention. Achieves a sufficiently insensitive performance of 1.1 to 1.6 amperes (A) and a firing time of 0.57 to 0.90 mm in response to a request for a non-ignition current value of 1 amperes (A). High-speed operation is achieved within seconds and 1 millisecond (ms).

As described above, it is possible to solve the problem which has been extremely difficult to achieve in the past, and as a result, it has become possible to use it as an ignition device for an impulse thruster which operates in an extremely short time.
