Description

[Detailed description of the invention] The present invention relates to a method of manufacturing a firework, particularly a toy firework.

Conventionally, in toy fireworks such as Christmas crackers, friction is generated internally by pulling a drawstring connected to the outside, and the ignition method is one in which ignition is caused by this friction, and the other is the ignition method in which the fire is ignited by the friction, as in the case of Franzyu crackers. There are two types of fire methods: 1. Both are made of paper and are filled with a plaster (hereinafter referred to as a sounding agent) K that is filled inside the shell, which is then burned to enjoy the bursting sound of the fireworks.

The present invention was made in view of the improvement of toy fireworks based on the above description, and a detailed explanation of the present invention will be given below with reference to the drawings. FIG. 2 is an example of a cross section of a toy firework according to the present invention, and the portion corresponding to the conventional outer shell material such as paper or plastic is the outer shell λ1j in (1). This shell material (1) comprises a fire extinguishing agent, a nonflammable agent, and a binder, which will be described later. That is, (1) chlorate/perchlorine as a fire extinguisher.
1I salt, etc. to form a mixture, sulfur, and, if necessary, an appropriate metal oxide, (?) the smoke ^ [1, the main body for adjusting the combustion rate, and 17, a nonflammable agent, which is an inorganic compound. , +3+ -1 It consists of a combustible material for solidifying each drug.

Reference numeral (2) in FIG. 1+IK indicates a sounding agent that produces sound when the outer shell agent (1) burns and ruptures due to the propagation of flame.

Examples of the present invention will be described in detail below.

Example: If the compounding ratio of each compound in the shell agent and sound generating agent of the present invention is 1001ml1% (under J2J wt, expressed as %), the aspect of the shell agent is: Agent: Chlorine-ugly potassium...23 wt, % sulfur ・

Sulfur and dextrin in the above-mentioned example VCM, pyrotechnic agent,
In addition to its function as a binder, it also functions as a fire extinguishing agent, and when preparing each agent, the formulation can be changed as appropriate depending on the purpose and use.

Examples of other drugs used as shell agents are as follows.

Fireworks agent: potassium perchlorate, sodium chlorate, sodium perchlorate, aluminum oxide Retardant: 91st calcium, magnesium carbonate, magnesium sulfate, zinc carbonate, zinc sulfate, binder: gum arabic solution For example, the production of the vinyl emulsion shell agent (1) is as follows:
The above blend of Lm, potassium chlorate, and ferric oxide 11 *

ru. The texture/liquid containing each drug obtained by the step srζ, that is, the shell agent, is in the form of a slurry.

Next, pouring into the mold (referred to as "original pouring" under +21) will be explained in detail.

Figure 1 shows a base material (31 is paper) and an approximately disk-shaped outer shell material 1 (1
) is shown in the plan view when the base material (3) is filled with the sounding agent f2'+Vi in advance. FIG. 2 is a sectional view of the reservoir showing the filling situation. Number of repetitions of spraying shell agent - J@ Can you create your favorite toy fireworks by combining various ordering and arrangement methods? υru. As an embodiment shown in FIG. 3, for example, (1) first pour the outer shell agent (1), dry the outer shell agent, and then (Q) pour the sounding agent (2) onto the outer shell net that has been dried and solidified. Spray, (repeat the original injection of shell agent, dry,
Let solidify. Figure 4 shows a detailed explanation of Figure 5, followed by repeating the original notes for the number of sounding agents, 4J, and the number of shells. FIG. 5 shows a paper material with a picture of a grasshopper on which sound-producing agents were arranged in a straight line at approximately equal intervals, and then a shell agent was applied. By igniting at the position (4) in the figure, the sounding agent 12) will burst one after another, and the line shape of the locust will appear to be moving.

The above example shows one example of the method for manufacturing the toy fireworks of the present invention, and the fire extinguisher, nonflammable agent, and binder used are not limited to those in the above example, but other sound-producing agents may also be used. Each component can also be changed as appropriate depending on the purpose and use, and the point is that the method for producing toy fireworks of the present invention is such that each of these agents can be integrated to provide the desired fireworks.

The effects of the toy firework of the present invention obtained by the above method will be described in detail below.

■ The process has a simple structure, which makes the manufacturing cost low.

■ As mentioned above, the shell material based on the present invention is already muddy at the time of original injection, so the safety of the manufacturing process is IP <

(Foam Toy fireworks V (Y) require the burning speed of the toy fireworks. In other words, fireworks that burn out within a short time after ignition cannot be commercialized.On the other hand, It's slow and memorabilia (it's like 2 cracks one after another), so it's not interesting as an 11-piece piece, and in order to bring out that whiteness, you need something with an appropriate burning speed. In the present invention, the combustion speed can be adjusted by adding a laxative such as carbonic acid run uno 4, which is relatively easy to obtain, and can be adjusted freely and easily depending on the type of fireworks. V (can be changed and can meet the preferences of the players.

(4) The outer shell agent of the present invention is a mixture of compounds that are hard and slow-flammable in normal state, and the residue of the outer shell agent at the combustion edge does not become ash and still maintains the normal state of η11< It is solid. Does this mean that the outer shell material is flexible and produces a low plosive sound? (There is no 4 tl, but because the outer shell agent is strong,
This allows you to enjoy a fully satisfying plosive sound.

By using the above h" method, it is possible to change the combination of various shell agents and sounding agents as appropriate. Different/Lies, or inverted working type of fireworks are not available, providing an interesting fireworks for recreationalists, and the!
J, influence 11 is large.
