Abstract

The leaf tobacco's stem was distilled with steam to give the low nicotine content fibroid material and the product was mixed with the leaves of a larch and a needle-leaf tree, dried at 50-70≰C and ground in 120-150mesh. The mixture was blended with a insecticidal component as synthetic pyrethrin or synthetic allerthrin, an assistant for combustion, a binder, and pigments to give the mosquito (in cence) stick coil.

Description

Manufacturing method of mosquito scent

The present invention is prepared by adding the saline powder to mosquito scents and steamed distilled leaf tobacco to remove the nicotine component at a low concentration, dried at 50-60 ℃ and then pulverized in 120-150 mesh and the general synthetic pyredrin and The present invention relates to a method for producing a mosquito repellent, characterized in that by adding a combustion aid, a binder.

An object of the present invention is to obtain a pesticidal effect by combining the fibers of coniferous leaves (leaved pine leaves, larch leaves) and nicotine components extracted and removed as a cooperative agent (synergist) and a combustion agent.

Conventional methods for producing mosquito scents in Korea are kneading and molding of preservatives, combustors, combustors, pigments, etc. as an adjuvant to synthetic allerthrin or synthetic pyrethrin as an insecticide in a raw powder which may be a mosquito scent. After that, it was common to dry it and commercialize it. However, since the domestic medicines such as mosquito-flavored powder raw materials and pesticides were sold solely in the domestic market, they were sold only by processing and mixing, so that no unique domestic products were developed.

The present inventors have succeeded in newly developing as a satisfactory pesticide supplement after researching various follow-up studies focusing on importing mosquito repellent raw materials (pesticides and pesticide supplements) into domestic resources.

Iii) Pyrethrin component has been extracted and used, but in recent years, it is well known in the art that synthetic pyredrin or synthetic alledrin is commonly used as a substitute.

科)의 낙엽송잎과 엽연초줄기(담배나무)의 섬유질등이, 살충약제의 유효성분으로 알려진 피레드린 또는 알레드린등에 대하여 협력효과(協力效果 Synergism)가 있음을 발견하고 본 발명을 완성하게 된 것이다.According to the research of the present inventors, as an insecticide, the leaves of red pine or red pine, which are evergreen trees of conifers, which are widely distributed in Sanya,

The fiber of larch leaf and tobacco leaf (cigarette) of the field, has found a cooperative effect (協力 效果 Synergism) against pyredrin or allledin, which is known as an active ingredient of pesticides, and completed the present invention. .

That is, it is known that the fiber of the leaf tobacco stem, which is distilled by water vapor and low in nicotine component, is mixed with the ground pine powder and larch powder, which are common coniferous leaves, dried at 50-70 ° C., and then ground to 120-150 mesh. Mosquito repellent is obtained by adding and kneading and molding the synthetic pyredrin or synthetic allredrin, a combustion aid, a binder and a pigment.

As it is well known that the leaf tobacco stem in the present invention by steam distillation to a low concentration of nicotine components, tobacco tree stems contain a large amount of nicotine components that are harmful to the human body and are highly irritating to the human body, and thus remove the nicotine components at low concentrations and alleviate them. The synergistic effect of the insecticide is sufficient to obtain, as well as the powder of the conifer itself also acts as a smoker and a combustor, so it is not necessary to add a combustor or smoker separately as in the case of mosquito incense as in the prior art. This will be.

The optimum blending ratio of the coniferous leaf powder used in the present invention and the fibrous powder of the leaf tobacco stem was 26.5%: 32.6%, which was most efficient in the cooperative effect.

In addition, as a pesticide used in the present invention, a small amount of 0.3 g-0.8 g of known synthetic pyredrin or synthetic alledrin, etc., sufficiently brings the insecticidal effect as a synergist. Starch, gum arabic, and CMC, known as other additives, are used as mosquito repellent binders in the same amount of 1: 1: 1 each, and a small amount of saltpeter (NaNO ₃ ), known as a coarse additive, is added to continuously burn the mosquito repellent. Add as a softener.

The above mixture is uniformly stirred and mixed to form a dry shape to obtain a mosquito flavor.

Experimental Method

10 mosquitoes were placed in two 1m ² glass hoods, and each mosquito flavor and the present invention were burned separately and the mosquitoes fell. The average time was 1.25 minutes in the conventional commercial product. The invention was 1.20 minutes, so that the insecticide effect was about the same as the conventional imported goods.
