DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a new base material for mosquito coils. More particularly, the present invention relates to a base material which is smooth in raw material procurement, has little irritating odor when smoked by a mosquito coil, and is useful for producing a high-quality and low-cost mosquito coil, and a mosquito coil containing the base material.

[0002]

2. Description of the Related Art Conventionally, mosquito coil incense sticks have been prepared by using pyrethrum extract cake powder, wood powder, cedar, tea, stalk and leaf powders, etc. as a flame retardant, binders such as corn starch, active ingredients, flavors, pigments, fungicides, etc. Is added, water is further added, and the mixture is kneaded, molded into an arbitrary shape, and dried to be manufactured.

[0003]

However, none of the above-described flame retardants is satisfactory in terms of stable supply of raw materials, cost, irritation of smoke, color tone, and the like. In addition, when smoking, the difference between the raw wood (pine, cedar, etc.) of the wood flour causes a large difference in the ignition time and the amount of smoke generated, and the irritation causes damage to the eyes and throat. Was also seen. On the other hand, in recent years, there has been a demand for the development of a fuel-supporting agent that can be sufficiently used for maintaining or protecting forest material resources and for plant materials that are waste materials in other industries.

[0004]

SUMMARY OF THE INVENTION The present invention provides a method for molding
The weight of the incinerated material which was ignited until the residue became constant temperature was about 10 (W / W)% or less as compared with that before the ignition, or hydrochloric acid was added to the ashed material, followed by boiling and drying. 10% (W / W)% or less of the weight of the product before ignition, or 10
After drying at 5 ° C for 5 hours, the mixture is allowed to cool in a desiccator, and the difference between the weight after cooling and the weight before cooling is 12 (W / W)% or less and the particle size is adjusted to 50 mesh or less. The present invention relates to a mosquito coil base material and a mosquito coil which are characterized in that they contain orange peel as a part of the raw material.

[0005] The orange peel used in the present invention is generally used as animal feed, and the orange peel has substantially the same properties as a flame retardant after being dried. That is, the plant fiber content and the degree of combustion are exactly the same if the dry state is the same. In particular, since orange peel can be kept almost constant for almost a year, it satisfies an excellent condition for procurement of a mosquito coil raw material base material.

Next, orange peel has considerable insect attracting power, and is expected to have an insect attracting effect.

[0007] Orange peel has a high moisture content, and the powder obtained by natural or forced drying is crushed to obtain a powder.
The mosquito coil thus produced had no brittleness and sticking at the time of molding, had little shrinkage even at the time of drying, had good mechanical strength after drying, and had no error in the ignition time. That is, since this powder is rich in fibrous material, if the mosquito coil incense blended and molded is examined in detail, it is porous but the strength is exactly the same as the conventional product, and the heating area, By increasing the spreading area, local overheating of the pyrethroid insecticidal component in the mosquito coil can be avoided,
The pyrethroid insecticidal component is effectively evaporated.

[0008] As described above, orange peel is used to form a mosquito coil with the dried product. At the time of molding, the orange peel does not have any foreign substances such as wood chips and soft chips. Or crucible made of porcelain 450-550
C. for 1 hour, put the orange peel in a crucible, gradually raise the temperature and ignite at 450-550.degree. C. until the residue becomes constant weight, 10% (w / w)% or less of the husk, 10% (v / v)% hydrochloric acid was added to the incinerated product, and the mixture was boiled for 5 minutes and dried. About 10% (w / w)% or less of the orange peel of
For 5 hours, and then allowed to cool in a desiccator (in silica gel). After the treatment, the difference between the weight when the weight of the orange peel becomes constant and the weight of the orange peel is 12 (w / w).
w)% or less and its particle size is adjusted to 50 mesh or less and used.

[0009] The amount of orange peel mixed into the incense stick may be the amount used as a usual flame retardant, and the amount in the incense stick is 1 to 80 (w / w)%, preferably 5 to 40 (w).
/ W)%.

Furthermore, the incense stick of the present invention can be produced by appropriately mixing an active ingredient such as a pyrethroid-based insecticide and the like, and also by appropriately mixing a repellent, a fragrance, a fungicide, a coloring matter and the like according to the purpose of use.

[0011]

The present invention is a mosquito coil that has no irritating odor, no peculiar odor and no unpleasant odor as described above, has good persistence in smoking, and can be produced at extremely low cost.

[0012]

EXAMPLES The present invention will be described below with reference to examples, but the present invention is not limited to these examples.

As shown in Table 1 below, a dried powder of orange peel was prepared to have a mesh size of 50 mesh or less.
Tab powder, wood powder, and d1, d-T80-aresulin were added and mixed in predetermined amounts. To this mixture, malachite green (colorant) and dehydroacetic acid (antifungal agent) previously dissolved in hot water of about 40 ° C. are added, kneaded for about 10 minutes, and then molded and dried to obtain a mosquito coil of the present invention (per one piece). About 13 g) were obtained. The following test was performed using the obtained sample. A control obtained in the same manner except that cedar powder was used instead of orange peel was used as a control.

[0014]

[Table 1]

Embodiment 1 FIG. Irritant odor test The incense was smoked in a glass cylinder having a diameter of 20 cm and a height of 40 cm, and the irritating odor was tested. As a result, the irritating odor was smaller in A and B than in the control.

Embodiment 2 FIG. Long-time test at night A long-term continuous test of about 8 hours from bedtime to the next morning was performed in a sealed 4.5 tatami room, and the control received an irritating smell. No abnormality was found.

Example 3 One end of each of the sample specimens A, B, and the control was ignited and left in a room with no wind, and the time for continuous smoking was measured.
The time 25 to 7 hours 30 minutes, and A and B showed the smoking time from 7 hours 30 minutes to 7 hours 50 minutes.

[0018]

When the mosquito coil is manufactured using the orange peel of the present invention as a base material, there is no irritating odor, peculiar odor and unpleasant odor, the working efficiency at the time of molding the mosquito coil is increased, It has various characteristics in the production of mosquito coils, such as good sustainability, extremely low cost due to the use of waste, and easy procurement of raw materials.
