[0003]

SUMMARY OF THE INVENTION Japanese Patent Laid-Open No. 57-1884
In the fuse for a pyrotechnic candle shown in 91, when the proportion of the flame coloring agent and the spark agent is increased, the unburned flame coloring agent and the spark agent cover the vegetable fibers, so that the burning of the vegetable fibers is insufficient. Therefore, the combustion residue may increase or the flame may go out, and continuous ignition of a plurality of candle wicks may not be performed reliably.
In order to avoid such a situation, it is necessary to keep the ratio of the flame colorant and the spark agent very low, and the flame and the crackle of the remarkable color only by adding a small ratio of the flame colorant and the spark agent. I couldn't enjoy the sparks that burst. Further, a starch paste, a chemical paste, etc. other than a nitrified cotton adhesive is applied to the surface of a cotton thread, a staple thread, a synthetic thread, etc., as shown in an automatic ignition candle disclosed in Japanese Patent Application Laid-Open No. 58-49830. , The continuous burning is difficult to continue,
The fibrous body in which metal powder such as aluminum, magnesium and iron is adhered to the surface thereof burns like a sparkler with a small flame. When the filamentous material shown here is used for continuous ignition of an automatic ignition candle, the flame of the filamentous material itself is small, so that the candle may not be ignited reliably and may not be ignited. Further, the fire of the filament itself may be extinguished on the way, and it is difficult to continuously ignite the candle. Further, in the igniting wire for candle ignition disclosed in JP-A-59-46420, since only a substance exhibiting a flame color reaction is adhered, only a colored flame is observed, and crackling occurs. You can't enjoy the sparks that burst. In addition, since nitrocellulose mixed with a substance exhibiting a flame reaction is directly attached to the filament, the unburned residue of the substance exhibiting the flame reaction covers the filament and combustion of the filament becomes insufficient, resulting in a tail-like combustion residue. More or the flame may go out. When the amount of combustion residue increases, the tail-shaped combustion residue hangs down in such a manner as to cling to the candle body, and this portion becomes a new combustion core and burns up. Further, there is no specific description about the method of manufacturing the squib.

[0004] An object of the present invention is to provide a squib for continuously igniting a plurality of candle wicks and a continuous ignition candle using the squib, wherein the flame does not extinguish during combustion and the combustion residue is small. In addition, you can enjoy sparks that burst out with flames and crackles of remarkable colors,
An object of the present invention is to provide a squib and a method for producing the squib used for candle ignition, which has a high visual appeal, and a continuous ignition candle with a high effect.

In the squib and continuous ignition candle used for candle ignition of the present invention,
Since the filamentous material serving as the central portion of the squib contains nitrified cotton and the coloring agent is present in the surface layer of the squib,
Both the filament and the coloring agent are quickly burned by the burning of the nitrified cotton, and are less likely to remain as tail-like combustion residues, and there is no fear that the flame will extinguish. Further, since the unburned residue such as the coloring agent does not cover the filament forming the squib, the tail-shaped combustion residue is attached to the candle body,
The situation that this part becomes a new combustion core and burns up does not occur. Further, since the coloring agent is present in the nitrified cotton on the surface layer of the squib, an extremely bright coloring flame can be obtained. In addition, since the metal powder and the like are adhered only to the surface of the filament containing nitrified cotton, the metal powder or the like is quickly burned off or flicked off from the surface of the filament by heat generated by the combustion, and the filament is rapidly burned. Also, there is little burning residue and there is no fear that the flame will go out. Furthermore, during the ignition for continuous ignition of the candle, not only the flame does not extinguish but the continuous ignition of the candle burning wick can be reliably performed, but also a tail-like combustion residue is generated. It is an excellent thing that enables you to enjoy a gorgeous production with a high visual appeal that allows you to enjoy the sparks that burst with the flames and crackling of the color that are even less noticeable.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a squib used for igniting a candle according to the present invention, a method for producing the squib, and a continuous ignition candle will be described in detail. The squib 1 used for igniting the candle of the present invention is a filament 2 containing nitrified cotton 3.
And metal powder 6, color forming agent 4,
Contains at least one selected from oxidizing agents 5. As an example of a method for manufacturing the squib 1, a nitrified cotton 3
After impregnating or applying the solution and primary drying, it is impregnated or applied with a nitrified cotton 3 solution in which at least one selected from a metal powder 6, a color forming agent 4, and an oxidizing agent 5 is dispersed. Drying. As another example of the production method, the filamentous body was impregnated or coated with a nitrified cotton solution, and was primarily dried to a semi-dry state, and then selected from the metal powder 6, the color former 4, and the oxidizer 5. There is a method of attaching at least one of them to the surface of the filament and then secondary drying.

As an example of the filament 2 containing the nitrified cotton 3,
For example, cotton, a plurality of those obtained by twisting cellulosic natural fibers such as hemp, etc. into a bundle or twisted yarn,
A filament 2 nitrified by a conventional method is used. For example, a method of immersing in a mixed liquid such as a concentrated nitric acid-concentrated sulfuric acid mixed liquid or a fuming nitric acid-acetic anhydride mixed liquid at around normal temperature, thoroughly washing with water, and then drying is adopted. At this time, the filaments 2 having various nitrification degrees are obtained depending on the composition of the mixed solution. A filament having a high degree of nitrification has a high thermal power at the time of combustion and has a high burning speed, but has a low tensile strength as the filament 2 and a filament having a low nitrification degree has a low thermal power at the time of combustion and has a low burning rate. In view of the above, it is necessary to adjust the composition of the mixed liquid so that the required tensile strength as the squib 1 for continuously igniting a plurality of candle burning wicks can be secured. To use the filament 2 thus obtained for the squib 1,
Usually, the filament 2 having a nitrification degree of about 6% to 12.5% of nitrogen can be used, and a nitrogen content of about 10% to 12%.
% Of the filament 2 is preferably used.

Further, as another example of the filament 2 containing nitrified cotton, for example, a plurality of filaments such as cellulose, natural fibers such as cotton and hemp, regenerated cellulose fibers such as rayon, and synthetic fibers such as polyethylene and polypropylene are used. The twisted or bundled yarn is impregnated or coated with a nitrified cotton 3 solution obtained by dissolving nitrified cotton 3 in an organic solvent or the like, and dried, and the dried filament 2 is used. It should be noted that cellulosic natural fibers and regenerated fibers can be said to be fibers which easily burn completely. Among them, cotton and rayon are preferably used because they have a small combustion residue. Although the nitrification degree and the like are not particularly specified for the nitrified cotton 3 used here, in practice, the nitrogen content of 10.7 specified in JIS standard K6703 is specified.
% Nitrocellulose having a degree of nitrification of about 12.2% is easily used and is preferably used. The nitrified cotton 3
As an organic solvent for dissolving, ketones such as acetone and methyl ketone, esters such as methyl acetate and ethyl acetate, cellosolves such as methylsolve and ethylsolve, alcohols such as methanol, and the like, or a mixture of a plurality thereof, as a true solvent And ethanol, isopropanol, butanol and the like are used as cosolvents. In order to adjust the solubility of the nitrified cotton 3, a diluent such as toluene or xylene may be used. Since these organic solvents have different properties such as solubility and boiling point with the nitrified cotton 3, depending on conditions such as the burning heat and the burning rate required by the squib 1,
What is necessary is just to select and use suitably. Further, the squib 1 ignites the plurality of candle wicks continuously.
A predetermined amount of a nitrifying cotton plasticizer or a nitrifying cotton softener may be added to the nitrifying cotton 3 solution so as to secure the moderately flexible rigidity required for the above. Here, as the plasticizer for nitrified cotton or the softener for nitrified cotton, phthalic acid-based plasticizers such as camphor, dibutyl phthalate, and dioctyl phthalate; fatty acid-based plasticizers such as dioctyl adipate and dioctyl sebacate; and epoxidized soybean oil. Epoxy plasticizers and the like can be used. Among these plasticizers or softeners, there are those which emit black smoke when burned depending on the amount of the plasticizer or softener. Care must be taken regarding the type and amount of the agent. For these reasons, fatty acid-based plasticizers such as dioctyl adipate and dioctyl sebacate are preferable for the addition to the nitrified cotton 3 solution, and the amount added is preferably 30 parts by weight per 100 parts by weight of the nitrified cotton of the nitrified cotton 3 solution. It is suitable that the amount is not more than 10 parts by weight, preferably not more than 10 parts by weight.

As the metal powder 6 used for the squib 1 of the present invention, generally available metal powder can be used.
Among them, powders of magnesium, magnalium, aluminum, titanium, iron, ferrotitanium, copper and the like are preferably used. These may be used alone or in combination. The type, particle size, blending amount, etc. of the metal powder 6 are determined according to the appearance of sparks required for the squib 1, the size and resilience of sparks, the frequency of sparks, the color of sparks, the degree of glitter, etc.
What is necessary is just to select and determine suitably. Here, the size of the metal powder 6 is not particularly limited as long as it can be appropriately selected and determined in consideration of the effect of the spark and the place of use, the scene, and the like.
Usually, the size of the metal powder 6 passes through about 30 mesh, and the metal powder 6 passing through about 60 mesh to about 150 mesh quickly burns or The squib 1 is repelled from the surface of the filament by the heat of the combustion, has a small amount of combustion residues, and continuously ignites a plurality of candle wicks.
Can be performed without hindrance and is preferably used. Furthermore, when it is necessary to control the appearance of sparks, the size of sparks, and the way of popping, the size is adjusted by a sorting method such as passing about 60 meshes and not passing about 100 meshes. The use of the metal powder 3 enables control and may be preferably used. Furthermore, 250 mesh or 300
The metal powder 6 of a fine powder that passes through a mesh is used alone or mixed with a larger amount of the metal powder 6 in a predetermined amount.
May be used.

As the coloring agent 4 used for the squib 1 used for igniting the candle of the present invention, a coloring agent for coloring a combustion flame can be generally used. Strontium compounds such as strontium carbonate and strontium nitrate as red agents, lithium compounds such as lithium carbonate as red agents, sodium compounds such as sodium oxalate as yellow agents, barium compounds such as barium nitrate and barium carbonate as green agents, Copper sulfate, flower patina,
A compound such as a copper compound such as copper oxide is used. Further, as the oxidizing agent 5, those usually used as an oxidizing agent can be used. Among them, chlorates such as potassium chlorate, perchlorates such as ammonium perchlorate and potassium perchlorate, sodium nitrate And nitrates such as potassium nitrate are preferably used.

The procedure for adhering at least one selected from the group consisting of the metal powder 6, the coloring agent 4 and the oxidizing agent 5 into the nitrified cotton on the surface layer of the filament 2 containing the nitrified cotton used for the squib 1 of the present invention is as follows. After impregnating or applying a cotton solution, the filament 2
Perform primary drying to a semi-dry state leaving adhesive on the surface,
Next, at least one selected from the metal powder 6, the color former 4, and the oxidizer 5 may be adhered to the surface of the filament, and then subjected to secondary drying. Further, using a solvent for nitrifying cotton, the nitrifying cotton on the surface of the filament 2 is dissolved to give an adhesive property, and at least one selected from the metal powder 6, the coloring agent 4, and the oxidizing agent 5 is attached.
May be adopted. In this case, as a means of adhesion, after imparting adhesiveness, it is made to pass through at least one kind selected from the piled metal powder 6, color forming agent 4, and oxidizing agent 5, and is applied and attached with a brush or other equipment. Means of letting, sprinkling, spraying, etc. can be taken. Further, the attachment site of the filament 2 containing the nitrified cotton, to which at least one selected from the metal powder 6, the color former 4, and the oxidant 5 adheres, may be attached to the entire surface of the filament 2; It may be a part of the thread-like body 2, such as adhesion to only the top or side surface. Furthermore, the adhesion of the metal powder 6, the color former 4, and the oxidizing agent 5 to the filament 2 need not be uniform, and the metal powder 6, the color former 4 At least one kind of non-adhesion site selected from the oxidizing agent 5 is provided, and at least a certain kind of adhesion site selected from the metal powder 6, the coloring agent 4, and the oxidizing agent 5 is provided on the filament 2 at predetermined intervals. At least one kind selected from the metal powder 6, the color forming agent 4, and the oxidizing agent 5 has a change in the adhesion density selected from the metal powder 6, the color forming agent 4, and the oxidizing agent 5. For example, the squib 1 having at least one of various kinds of attached states selected from the metal powder 6, the coloring agent 4, and the oxidizing agent 5 is possible.

If the amount of the metal powder 6 and the coloring agent 4 contained in the nitrified cotton 3 in the surface layer of the squib 1 of the present invention is too small, the tail-like combustion residue is small, but effective spark generation and remarkable coloring are caused. If the amount is too large, the generation of effective sparks and remarkable coloring can be expected, but not only the number of tail-like combustion residues increases but also the burning speed becomes slow, which is not preferable for the squib 1. On the other hand, when the degree of nitrification of the nitrified cotton 3 contained in the filament 2 containing nitrified cotton is low or the content thereof is small, the amount of adhesion of the metal powder 6 and the coloring agent 4 is low because the firing power of the squib 1 is low. Even if the amount is small, the tail-like combustion residue increases, and the combustion speed decreases. On the other hand, when the nitrification degree of the nitrified cotton 3 contained in the filament 2 containing the nitrified cotton is high or the content thereof is large, since the firing power of the squib 1 is strong, the metal powder 6,
Even if the amount of the coloring agent 4 attached is large, the tail-like combustion residue is small,
Also, the burning speed of the squib 1 does not decrease. From these facts, the amount of the metal powder 6, the coloring agent 4, and the oxidizing agent 5 attached to the squib 1 according to the present invention is more effective depending on the degree of nitrification of the nitrified cotton contained in the filament 2 and the content thereof. In order to prevent the sparks from jumping out and remarkable coloring, and to reduce the burning speed of the squib 1 when continuously burning a plurality of candle wicks with a small tail-like combustion residue,
It may be determined appropriately.

Here, the metal powder 6 and / or the color former 4
When increasing the amount of adhering, a predetermined amount of the oxidizing agent 5 is mixed with the metal powder 6 and / or the coloring agent 4 and used to reduce combustion residues and continuously ignite a plurality of candle wicks. Function can be performed without hindrance.
Further, the oxidizing agent 5 is replaced with a metal powder 6 and / or a coloring agent 4.
By using them together, the effect of generating sparks that burst vigorously is enhanced, and the color of the combustion flame becomes more vivid and effective.

In the squib 1 of the present invention, the metal powder 6,
At least one selected from the coloring agent 4 and the oxidizing agent 5 is contained in the nitrified cotton 3 in the surface layer of the squib 1. An example of a manufacturing method for obtaining the squib 1 having the above configuration will be described below. A predetermined amount of industrial-use nitrocellulose is added to a thread-like solvent such as ethyl acetate to a thread-like body 2 in which a plurality of yarns obtained by twisting the cellulose-based natural fibers such as the cotton and hemp are further bundled or twisted. And then impregnated or coated with a nitrified cotton 3 solution whose viscosity has been adjusted with a co-solvent, diluent, etc.,
Primary drying with hot air, then metal powder 6, color former 4,
Nitrified cotton 3 in which at least one selected from oxidizing agents 5 is dispersed
The solution is impregnated or applied, and then secondary dried with hot air to produce the squib 1. Further, using the filament 2 which has been nitrified by a conventional method, impregnated or coated with a nitrified cotton 3 solution in which at least one selected from the metal powder 6, the color former 4, and the oxidizer 5 is dispersed, and thereafter, Drying may be used. Further, as another manufacturing method, the metal powder 6, the color former 4, the oxidizer 5
At least one kind selected from among the above may be sprinkled, or attached by means such as dusting. According to the manufacturing method employing such a two-step procedure, the present invention includes at least one selected from the metal powder 6, the coloring agent 4, and the oxidizing agent 5 in the nitrified cotton 3 in the surface layer of the squib 1. Is obtained. Here, if a nitrified cotton 3 solution in which an oxidizing agent 5 is dispersed together with the color forming agent 4 is used, the color developability can be further improved. The conditions such as the drying temperature, drying time, and air volume during the primary drying and the secondary drying are determined by the concentration of the nitrified cotton 3 solution, the amount of the nitrified cotton 3 solution contained in the filament 2,
The amount may be appropriately determined in consideration of the amount of the nitrified cotton 3 solution applied to the filament 2 and the like.

An example of another manufacturing method will be described below.
The cotton, the cellulosic natural fibers such as hemp, etc. are twisted into a plurality of filaments formed into bundles or twists, and a predetermined amount of industrial nitrocellulose is dissolved in a nitrifying cotton solvent such as ethyl acetate. Further, after impregnated or coated with a nitrified cotton solution whose viscosity has been adjusted with a cosolvent, a diluent, etc., it is primarily dried to a semi-dry state with hot air, and then a predetermined amount of metal powder 6, the coloring agent 4, the oxidizing agent 5 At least one kind selected from the above is attached to the surface of the filament by means such as sprinkling or spraying, and then secondary dried with hot air to produce the squib 1. Conditions such as drying temperature, drying time, air volume, etc. in the primary drying and the secondary drying are the concentration of the nitrified cotton solution, the amount of the nitrified cotton solution contained in the filament, and the amount of the nitrified cotton solution applied to the filament. It may be appropriately determined in consideration of the above. As the drying means, in addition to the drying with the hot air, wind drying, drying with a heat source such as infrared rays, natural drying, vacuum drying, vacuum drying, etc. Squib 1
The most suitable one may be selected in consideration of conditions such as whether the state is good or not. Further, the primary and secondary drying steps may be separate steps before and after the metal powder 6 and the like are adhered to the surface layer portion of the filament, or the primary and secondary drying may be performed as a continuous drying step. Meanwhile, a step of attaching the metal powder 6 and the like to the surface layer portion of the filament at an appropriate portion in the middle thereof may be adopted.
