本発明は、点火薬、特に玩具煙火の点火に適し
た点火薬に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ignition powder, particularly an ignition powder suitable for igniting toy fireworks.
小型発煙筒、小型ロケツト等の玩具煙火は、最
近無線操縦等の遠隔操作により点火される場合が
多くなつて来ている。 Recently, toy fireworks such as small smoke bombs and small rockets are increasingly being ignited by remote control such as radio control.
これらの玩具煙火の点火に用いられる点火薬

望まれる。 The ignition powder used to ignite these toy fireworks does not violate the regulations of the Explosives Control Law, does not ignite when a minute current is passed through a control radio wave or other noise radio waves, and is a suitable but not too large powder. It is desirable to be able to reliably ignite at a large ignition current and also to be able to burn the pyrotechnic agent directly without the presence of an intermediate agent.

な通電流が高すぎる。 Explosives such as tricinate, rhodan lead, and diazodinitrophenol are conventionally known as igniters for ordinary electric detonators, but these detonators cannot be used in toy fireworks due to regulations under the Explosives Control Law. In addition, the gas pressure is high and a separate intermediate agent is required to ignite the smoke generator, so it cannot be used directly to ignite colored smoke generators in toy fireworks. Mixtures of metal oxidizing agents and metal reducing agents, such as Pb 3 O 4 , BaCrO 4 etc. and FeSi,
Combinations with B, Zr, Mg-Al alloys, Al, etc. are safe ignition agents that are not regulated by the Explosives Control Law and are candidates for use as igniters for toy fireworks. Among them, the combination of FeSi and Pb 3 O 4 has traditionally been used as an ignition agent or heating agent for fireworks and pyrotechnics, but this two-flavor mixture can be applied to wire bridges as an igniter. If it is too high, the current required for ignition is too high.

る。 The present inventors found that an ignition ball applied to a Pt-Ir wire bridge with a resistance of 0.7Ω did not ignite when energized at 0.3 amps for 2 minutes, but ignited in an extremely short time when energized at 0.6 to 0.8 amps, and ignited uniformly. As a result of intensive research in order to obtain an igniter that generates a flame, it was possible to achieve the above object by adding Zr to the above two-flavor mixture, leading to the present invention.

Furthermore, it can be used directly to ignite colored smoke powders or light powders for fireworks without using any intermediate chemicals, and is particularly suitable as an ignition powder for toy fireworks.

い。 These ignition powders are made into an ignition ball using a Pt-Ir wire bridge, and when the resistance value is approximately 0.72 ohm, the resistance is 0.6~
It ignites at 0.8 amperes, and the range of ignition current values is narrow. Furthermore, the safety of these igniters is higher than that of conventional igniters using the above-mentioned explosives. In addition, there is no need to use potassium chlorate or potassium bromate, which are relatively sensitive to friction, unlike conventionally known materials (for example, Zr and potassium chlorate, or charcoal and potassium bromate), making it an important choice for fireworks manufacturers. There are no manufacturing safety problems with the mixture of so-called "Red Tel" and Zr.

は発火しない。 FIG. 1 shows a sectional view of a toy smoke cylinder using the igniter of the present invention. In the figure, 1 is an elongated metal tube, and 2 is a smoke-generating agent, for example, a red smoke-generating agent made by mixing and granulating red dye, potassium chlorate, dextrin, dust, etc. Reference numeral 3 denotes an electric bridge wire, which is connected to the end of the core wire 5 of the leg wire 4. The electric bridge wire 3 is coated with the ignition powder 6 of the present invention to form an ignition ball, which is embedded in the smoke generating powder 2. The ignition powder is, for example, 75 parts by weight of Pb 3 O 4
20 parts by weight of FeSi and 5 parts by weight of Zr are mixed, and 2 parts by weight of a butyl acetate solution of nitrified cotton is used as a binder. The leg line 4 passes through the embolus 7 and is integrated with the embolus 7. The embolus 7 is press-fitted into the end of the metal tube 1 and fixed with an adhesive 8 to form a sealing plug.
9 is a lid, and 10 is a smoke hole. When such a smoke bomb is mounted on, for example, a radio-controlled model airplane, the landing gear 4 forms a circuit with the battery of the onboard receiver, and is energized by a signal from a transmitter from the ground, the ignition charge is e.g. 100% sure fire when energized, smoke generating agent burns, 3 smoke holes 10
Red smoke was spewed out one after another, and the plane left a spectacular trail of red smoke. This smoke bomb does not ignite using radio waves used to control airplanes.
