JPH04308512A - Base for mosquito-repellent incense and mosquito-repellent incense - Google Patents

Abstract

PURPOSE:To obtain an extremely inexpensively producible base for mosquito- repellent incense, having no irritating smell, no peculiar smell and no unpleasant smell, showing excellent durability in smoking by using orange peel, obtainable constantly almost throughout a year, as part of raw material. CONSTITUTION:For example, dried powder of orange peel prepared into <=50 meshes is blended with given amounts of pyrethrum powder, flour of Litsea glauca Sieb and dl or d-T80-allethrin, mixed with prewarmed colorant and mildewproofing agent, kneaded, molded and dried to give a mosquito-repellent incense. When the mosquito-repellent incense is produced by using orange peel as a base, the mosquito-repellent incense has no irritating smell, no peculiar smell and no unpleasant smell, and operation efficiency in molding of mosquito- repellent incense is increased. The mosquito-repellent incense has excellent durability in smoking and is inexpensive because of the use of a waste.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a new base material for mosquito coils. More specifically, the present invention relates to a base material that is useful in the production of high-quality, inexpensive mosquito coils that can be smoothly procured, has almost no irritating odor when the mosquito coils are smoked, and mosquito coils that contain the base material.

0002

[Prior Art] Conventionally, mosquito repellent incense sticks have been made using pyrethrum extract powder, wood powder, cedar, tea, tab leaf powder, etc. as combustion supporting agents, binders such as corn starch, active ingredients, fragrances, pigments, fungicides, etc. is added, water is added, kneaded, molded into an arbitrary shape, and dried.

0003

[Problems to be Solved by the Invention] However, all of the above-mentioned combustion supporting agents are unsatisfactory in terms of stable supply of raw materials, cost, smoke irritation, color tone, etc. And during the smoking process, the logs used to make the wood powder (
For example, differences in the burn time (for example, pine and cedar) caused large discrepancies in the burning time, and in addition, the amount of smoke emitted was large, and the irritation was seen to hurt the eyes and throat. On the other hand, in recent years, from the viewpoint of preserving or protecting forest resources, there has been a desire for the development of combustion supporting agents that can be fully utilized even for plant materials that are waste materials in other industries.

0004

[Means for Solving the Problems] The present invention relates to a mosquito coil base material characterized by containing orange peel as a part of the raw material, and a mosquito coil containing the base material.

[0005] The orange peel used in the present invention is generally used as animal feed, and after being dried, orange peel has substantially the same properties as a combustible agent. That is, the vegetable fiber content and combustion condition are exactly the same if the drying conditions are the same. In particular, orange peels can be procured at a constant rate almost all year round, which satisfies excellent procurement conditions for the raw material for mosquito coils.

[0006] Orange peel has a considerable insect-attracting power and is expected to have an insect-attracting effect.

[0007] Orange peel has a high water content, and it is dried naturally or by force and then ground to obtain a powder.
The mosquito repellent incense produced using this method was free from brittleness and sticking during molding, had little shrinkage during drying, had good mechanical strength after drying, and had no error in burn time. In other words, this powder is rich in fibers, so if you carefully examine the structure of a mosquito coil molded with this powder, you will find that although it is porous, its strength is exactly the same as the conventional product, and the heating area and By increasing the diffusion area, local overheating of the pyrethroid insecticidal ingredients in the mosquito coil can be avoided,
The pyrethroid insecticidal component is effectively evaporated.

[0008] As mentioned above, the dried orange peel is used to mold mosquito coils, but when molding, the orange peel must be free of foreign substances such as wood chips and straw, and must be made of platinum or quartz. 450-550 porcelain or porcelain crucible
Ignite at ℃ for 1 hour, put the orange peel in a crucible, gradually increase the temperature and ignite at 450-550℃ until the residue reaches a constant weight, the amount of ash is equal to that of the orange before ignition. 10 (w/w)% or less compared to the skin of About 10 (w/w)% or less of the orange peel, when the orange peel is heated to 105℃
After drying for 5 hours in a desiccator (containing silica gel), the difference between the weight of the orange peel when the weight of the orange peel became constant after treatment and the weight of the orange peel was 12 (w/w).
% or less and the particle size is 50 mesh or less for use, so there are no limitations as long as it meets the above criteria.

[0009]The amount of orange peel added to the incense stick may be the amount normally used as a combustion support agent, and the amount added in the incense stick is 1 to 80 (w/w)%, preferably 5 to 40 (w/w).
/w)%.

Furthermore, the incense stick of the present invention can be manufactured by adding active ingredients such as pyrethroid insecticides, as well as repellents, fragrances, fungicides, pigments, etc., depending on the purpose of use.

[0011]

[Function] As described above, the present invention provides a mosquito coil that is free from irritating, peculiar, and unpleasant odors, has good durability during smoking, and can be manufactured at an extremely low cost.

0012

[Examples] The present invention will be explained below using Examples, but the present invention is not limited to these Examples.

[0013] As shown in Table 1 below, dried orange peel powder prepared to a size of 50 mesh or less, pyrethrum powder,
Tab flour, wood flour, and d1,d-T80-allethrin were added and mixed in predetermined amounts. Malachite green (colorant) and dehydroacetic acid (antifungal agent), which had been dissolved in warm water at about 40°C in advance, were added to this mixture, mixed for about 10 minutes, then molded and dried. About 13 g) was obtained. The following tests were conducted using the obtained samples. A control sample was obtained in the same manner except that cedar powder was used instead of orange peel.

[0014]

[Table 1]

Example 1. Stimulating odor test The incense sticks were each smoked in a glass cylinder with a diameter of 20 cm and a height of 40 cm, and a test for the irritating odor was performed.As a result, the irritating odor of A and B was less than that of the control.

Example 2. 4. Closed for long night test.
As a result of a long-term continuous test lasting approximately 8 hours from bedtime to the next morning in a 5-tatami room, the control sample experienced an irritating odor, but A and B did not exhibit any abnormalities.

Example 3 In a windless room, samples A, B, and one end of the control were ignited and left to stand, and the continuous smoking time was measured.
The smoking time ranged from 25 minutes to 7 hours and 30 minutes, and A and B showed smoking times of 7 hours and 30 minutes to 7 hours and 50 minutes.

[0018]

Effects of the invention: When mosquito coils are manufactured using the orange peel of the present invention as a base material, there is no irritating odor, peculiar odor, or unpleasant odor, and the work efficiency during molding of mosquito coils is improved, and the It has a variety of characteristics for the production of mosquito coils, such as good sustainability, extremely low cost since it uses waste, and easy procurement of raw materials.
