DESCRIPTION
AN INSECTICIDE COMPOSITION FOR INDUSTRIAL HYGIENL AND A WICK FOR USED THEREAL
Technical Field The present invention pertains, in general, to an electric fumigation insecticide liquid composition and a wick for a fumigator employing the same and, more particularly, to an industrial electric fumigation insecticide liquid composition and a porous absorbent wick for a fumigator employing the same.
Background Art
Generally, use of an insecticide for hygienic insects, such as mosquito liquid, is achieved with the aid of an electric fumigator. Since the electric fumigator is usually designed so as to be used in the home and to be used in a small space having an area of about 10 - 15 m2, a conventional electric fumigator is not suitable for large spaces, such as restaurants, offices, schools, hospitals, factories, or large shopping centers, and thus, it is necessary to use other kinds of electric fumigators or many conventional electric fumigators in large spaces . In such a case, purchase costs and power consumption of the electric fumigators are significantly increased, and the electric
fumigators are conspicuous because so many must be installed.
Hence, there is a need to develop not only a desirable electric fumigator but also an insecticide composition, which assures a desired insecticidal effect using only one electric fumigator.
With respect to this, Korean Pat. Application No. 1999-44505, which was submitted in 1999 by the applicant of the present invention, discloses an aqueous mosquito liquid for an electric vaporizer capable of being used in a large space, but there is described only an insecticide liquid composition for killing a mosquito in the above patent.
Meanwhile, a wick capable of drawing an insecticide solution is needed to effectively use the insecticide composition. In this respect, Korean Application for Utility Model Registration No. 2000-250886 discloses a wick applied to an electric vaporizer for mosquito liquid. In the above Utility Model, since the wick includes an external wick made of highly absorbent materials, such as clays, carbons, and wood powders, an internal wick made of fibers, such as cellulose, and a metal plate, it has a complicated structure. Additionally, since a detailed description of its structure is not revealed in the above Utility Model, its performance is questionable. Conventional mosquito liquid is produced so that an amount of 45m£ is used to kill mosquitoes in a small area of
3 - 4 pyeongs (9.92 - 13.22 m2) for 30 - 40 days provided that it is used for 10-- 12 hours per day, and thus, it is undesirably required to frequently replenish the mosquito liquid or to use many electric fumigators. Accordingly, there remains a need to develop an insecticide composition, which is safer than a conventional electric fumigation insecticide composition, and which is used in a large area for a desired time, and a wick applied to use with the same.
Detailed description of the Invention
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior arts, and an object of the present invention is to provide an industrial electric fumigation insecticide liquid composition, which can effectively exterminate hygienic insects, such as mosquitoes, in a large space using one electric fumigator, and which is economically applied to the electric fumigator.
Another object of the present invention is to provide a microporous wick, which is applied to a fumigator employing the insecticide liquid composition, and which can be used for a long time.

Further, the present invention provides a wick for an electric fumigator, including 1 - 14 wt% of inorganic powder, 0.1 - 10 wt% of organic .powder, 1 - 10 wt% of binder, and water as a balance.
At this time, the inorganic powder is at least one selected from a group consisting of clay, silica, alumina, talc, titanium, aluminum silica, extrusive rock powder, asbestos, activated carbon, steatite, diatomite, kaolinite, plaster, perlite, bentonite, gypsum, glass fiber, and asbestos fiber.

A better understanding of the present invention may be obtained through the following examples which are set forth to illustrate, but are not to be construed as the limit of the present invention. Furthermore, all % described in the following examples mean wt%.
EXAMPLE 1
A composition containing the above components was put into an electric fumigator.
EXAMPLE 2
A composition containing the above components was put into an electric fumigator.
EXAMPLE 3
A composition containing the above components was put into an electric fumigator.
EXAMPLE 4
A composition containing the above components was put into an electric fumigator.
EXAMPLE 5
A composition containing the above components was put into an electric fumigator.
Hereinafter, a detailed description will be given of a wick for an electric fumigator employing the insecticide liquid composition of the present invention.
The porous absorbent wick according to the present invention may include organic powder, which is produced by mixing wood powder, flue, pulp, and cellulose, a binder, and baked inorganic powder, or may include an organic material, an inorganic material, and a polymer material. The inorganic powder is exemplified by clay, silica, alumina, talc, titanium, aluminum silica, extrusive rock powder, asbestos, activated carbon, steatite, diatomite, kaolinite, plaster, perlite, bentonite, gypsum, glass fiber, asbestos fiber, and a mixture thereof, and examples of the binder include carboxy methyl cellulose (CMC) , wood powder, starch, polymer foam, aramic gum, gelatin, polyvinyl alcohol (PVA) , and a mixture thereof. The absorbent wick of the present invention, which is produced by shaping the above materials in accordance with a typical method, is microporous, and is designed to consume the insecticide liquid composition slowly so that the insecticide liquid composition lasts for a long time because the wick of the present invention absorbs a very small amount of insecticide liquid composition in comparison with a conventional absorbent wick mostly consisting of fibrous materials. With respect to this, it is preferable to use plaster, clay, diatomite, gypsum, and
perlite as the inorganic powder due to their plasticity, and CMC is the binder with desired insolubility to the solvent and plasticity. Most preferably, two or more kinds of inorganic powders are baked in conjunction with CMC and shaped to produce the absorbent wick. In the course of producing the absorbent wick, it is preferable that an amount of the binder is 1 - 10 wt% based on a total weight of the wick. Additionally, it is preferable to add the extender to the wood powder. The extender with a particle size of 100 μ or less, such as starch and hydroxy methyl cellulose, may be added to the inorganic powder with a particle size of 100 [M or less, mixed with a predetermined amount of water, kneaded using a mixer, extruded using an extruder, and dried to produce the porous absorbent wick. The resulting absorbent wick is microporous, and has a low porosity in comparison with a conventional absorbent wick mostly consisting of fibrous materials or sintered inorganic powder and starch, and thus, an amount of insecticide liquid composition absorbed into the porous absorbent wick of the present invention is relatively small, and the porous absorbent wick of the present invention is designed to consume the insecticide liquid composition slowly so that the insecticide liquid composition lasts for a long time. The porous absorbent wick of the present invention has components as described in the following Table 1, and its porosity is described in
the Table 1,
TABLE 1
%i The reason why the total of contents of the components constituting each sample is not 100 % is that each sample contains water as a balance.
As described above, in the case of an insecticidal method adopting fumigation, the insecticide composition according to the present invention can be effectively evaporated in an amount that assures a desirable insecticidal effect at 105 - 200°C, and can stably maintain the insecticidal effect for a long time.
Industrial Applicability As is apparent from the above description, the present invention provides an insecticide liquid composition and a wick applied to an electric fumigator employing the insecticide liquid composition, which can effectively exterminate harmful insects, such as
mosquitoes, using a single electric fumigator to significantly reduce economical burden and inconvenience of use, and which can avoid inconvenience in application of a conventional electric fumigator, employing 45m-£ of an insecticidal solution and intended for home use, to industrial fields, large restaurants, business centers and the like. In other words, the conventional home electric fumigator, designed so as to be used in a small space with an area of about 10 - 15 m2, is not fitted to accomplish the desired object in a large space, such as restaurants, offices, schools, hospitals, factories, or large shopping centers . However, the composition and wick for the electric fumigator according to the present invention contribute to easy achievement of the desired object in large spaces, such as restaurants, offices, ' schools, hospitals, factories, or large shopping centers.
Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
