Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incense stick and a base material for an incense stick.

[0002]

2. Description of the Related Art Although various incense sticks have been known so far,
Despite its excellent insecticidal efficacy, insecticidal incense for controlling mosquitoes, flies, etc. does not like the smoke generated during combustion, especially the irritation caused by smoke. It is being replaced by transpiration equipment.

[0003]

DISCLOSURE OF THE INVENTION The present invention has been made for the purpose of finding an incense stick which suppresses the generation of smoke during combustion and has reduced irritation by smoke, and a binder for an incense stick therefor. is there.

[0004]

According to the present invention, starch and bentonite are used in combination as a binder used in the production of incense sticks, and carbon powder is used as the main ingredient of the incense sticks. In particular, an incense stick that produces less smoke during combustion and is less irritating by smoke is obtained. That is, the incense stick and the base material for the incense stick of the present invention contain 3 to 45% by weight of starch, preferably 5 to 40% by weight, 1 to 30% by weight of bentonite, preferably 2 to 25% by weight and 40 to 90% by weight of carbon powder. It has a composition containing.

[0005] The starch used in the present invention is not particularly limited, and various starches obtained from candies, potatoes, rice, wheat, cassava and the like can be used alone or in combination. Further, examples of the carbon powder used in the present invention include powders of charcoal, activated carbon, coal, carbon black and the like, and their particle size is 100 μm or less.
It is preferable to use one containing at least wt%.

The incense stick and the base material for the incense stick of the present invention are starch,
Although it contains bentonite and carbon powder,
Insecticide active ingredients are contained as other ingredients in the case of insecticidal incense sticks. The insecticidal active ingredient is preferably a pyrethroid compound, such as pyrethrin, allethrin, prarethrin, transfluthrin, resmethrin, flamethrin, empentrin, etc., usually 0.01 to 3% by weight in a base for incense sticks or incense sticks, preferably 0.01-1
It is contained by weight%.

In addition to the incense stick and the base material for an incense stick, an extender, a combustion accelerator, a neutralizing agent, an antifungal agent, etc. can be appropriately added. Examples of the extender include sandalwood powder, sandalwood powder, Camphor, powder, Japanese cedar powder, cedar powder, willow powder, springwood powder, honoki powder, linden powder, spruce powder, yellow poplar powder, vine powder, acacia powder, porcupine powder, psyllium powder, psyllium powder, sawdust powder, cat powder, Kiri powder, Shioji powder, balsa powder, Lauan powder,
Birch powder, citrus tree powder, woody powder such as shiitake sardine tree powder, Asteraceae plant powder, Aceraceae plant powder, Mesaceae plant powder, Zinchoideaceae plant powder, Fusariumaceae plant powder, Moraceae plant powder, Asteraceae plant Dry powders such as powder, Lamiaceae plant powder, Rubiaceae plant powder, Loniceraceae plant powder and the like can be mentioned, and usually contained in an incense stick or an incense stick base material in an amount of 0 to 40% by weight.

Examples of the combustion accelerator include nitrates such as potassium nitrate and sodium nitrate, percarbonates such as sodium percarbonate, perhalogenates such as potassium perchlorate, and peroxides such as sodium peroxide. As the neutralizing agent, for example, citric acid, succinic acid, maleic acid, fumaric acid, tartaric acid, oxalic acid, malonic acid, malic acid, adipic acid, boric acid, benzoic acid, nicotinic acid, salicylic acid, ascorbic acid, glutamic acid, Examples thereof include aspartic acid, sorbic acid, phenylacetic acid, sodium dihydrogen phosphate, potassium dihydrogen phosphate and the like. The combustion accelerator and the neutralizer are usually 0 to 5% by weight in the incense stick or incense stick base material, respectively.
And 0 to 5% by weight. Examples of the antifungal agent include benzoic acid, sorbic acid, dehydroacetic acid, p-
Hydroxybenzoic acid, acids such as o-phenylphenol,
The salt and the ester are included, and usually contained in an incense stick or an incense stick base material in an amount of 0 to 2% by weight.

The base material for incense sticks of the present invention is prepared by adding an appropriate amount of water to starch and heating it to obtain a paste, bentonite, carbon powder, and, if necessary, an insecticidal active ingredient, a filler, a combustion accelerator, and a neutralizer. It is obtained by adding agents, mildewproofing agents, etc. and kneading with water, and molding it with a molding machine such as a press molding machine, extrusion molding machine, injection molding machine, or coating it on a flame-retardant thin plate such as non-combustible paper. The incense stick is manufactured by molding and then drying. When adding the insecticidal active ingredient, the active ingredient of the insecticidal active ingredient may be added as it is, or various preparations such as emulsion, oil, suspension and microencapsulated preparation may be added.

EXAMPLES Next, the present invention will be described more specifically by way of examples, but the present invention is not limited to the following examples. Example 1 Praletrin Emulsion [Praletrin (Pyrethroid compound) 0.08 part by weight, Himal BLZ (Surfactant manufactured by Matsumoto Yushi-Seiyaku Co., Ltd.) 0.01 part by weight, Hymar 1002Z (surfactant manufactured by Matsumoto Yushi-Seiyaku Co., Ltd.) 0.001 part by weight and Solvesso 150
(Exxon Chemical Organic Solvent) 0.009 parts by weight]
0.1 parts by weight, 20.0 parts by weight of wheat flour starch and a paste-like starch obtained by heating and mixing an appropriate amount of water, bentonite 5.0 parts by weight,
2.0 parts by weight of potassium nitrate, 2.0 parts by weight of citric acid, 0.2 parts by weight of sodium dehydroacetate and 70.7 parts by weight of charcoal powder are added, and an appropriate amount of water is further added, well mixed, kneaded, extruded and dried to prepare a stick-shaped insecticidal stick. Got

Example 2 The incense stick obtained in Example 1 was burned in a glass cylinder having a diameter of 20 cm and a height of 80 cm to examine smoke generation and irritancy. I could hardly feel it. The incense stick obtained in Example 1 was good in both ignitability and combustion sustainability. On the other hand, in the incense stick obtained by using 5.0 parts by weight of charcoal powder in place of 5.0 parts by weight of bentonite in Example 1, more smoke was generated compared with the incense stick obtained in Example 1, and a pungent odor was felt.

[0012]

EFFECT OF THE INVENTION The incense stick of the present invention has excellent properties such that smoke is hardly generated during combustion and almost no irritation is felt.
