이하, 본 발명의 작용을 설명한다.The operation of the present invention will be described below.

본 발명은 모기 기피 효과가 우수한 천연물질로써 유칼리나무잎 추출오일, 로즈마리잎 추출오일 또는 백리향 등 천연 추출오일을 단독으로 사용하거나, 이의 추출물 성분 중 일부의 성분만을 분리 추출하여 해충의 기피 효과를 발현할 수 있는 내부물질로 사용하고 추출오일의 외벽을 고분자 수지로 표면을 코팅하여 유적의 크기를 수에서 수백마이크로 크기를 갖는 마이크로캡슐로 이루어져 있다.The present invention uses natural extract oil such as eucalyptus leaf extract oil, rosemary leaf extract oil or thyme as a natural material with excellent mosquito repellent effect, or by extracting only some components of the extract components of the extract to express the repellent effect of pests It can be used as an internal material, and the outer wall of the extracted oil is coated with a polymer resin to form a microcapsule having a size of several hundreds of micrometers.

패취의 상부에 마이크로캡슐이 처리된 패드를 사용하고 하부에 밴드와 접착층으로 구성되어 있기 때문에 피부에 추출오일이 직접 접촉하지 않으므로 사용자의 불편함이나, 알러지의 발생을 막을 수 있는 것이다.Since the pad is treated with a microcapsule on the upper part of the patch and the band and the adhesive layer on the lower part of the patch, the extraction oil does not directly contact the skin, thereby preventing user's discomfort or allergy.

또한 본 발명의 방법으로 제조한 패취의 경우 제조방법이 간단하고 가격이 저렴할 뿐만아니라 추출오일 성분이 고분자 물질로 쌓여진 캡슐로 이루어졌기 때문에 유통과정에서 발생하는 오일의 기화로 인한 손실을 막을 수 있고 소비자가 모기의 기피효과를 원할 때 부직포의 일부에 압력을 가함으로써 해충의 기피효과를 최대화할 수 있는 것이다.In addition, in the case of the patch prepared by the method of the present invention, the manufacturing method is simple and inexpensive, and since the extracted oil component is made of a capsule stacked with a polymer material, it is possible to prevent loss due to vaporization of oil generated in the distribution process When mosquitoes want to evade, the pressure on a portion of the nonwoven can be maximized to avoid the pests.

한편, 본 발명의 해충기피용 패취의 제조시 마이크로캡슐 내에 기피제 대신 살충제를 충전시키므로서 해충을 제거시킬 수 있는 것이다.On the other hand, in the preparation of the pest repellent patch of the present invention it is possible to remove the pest by filling the pesticide instead of the repellent in the microcapsules.

상기와 같이 본 발명 해충기피용 패취는 고분자 벽재로 추출오일을 보호하고 있기 때문에 원하는 시기에 기피효과를 발현할 수 있으며, 캡슐이 함침된 패드부에 압력을 가하여 마이크로캡슐간의 마찰 내지 접촉에 의한 파손에 의해 내부의 기피제를 발산시키므로서 약효를 지속적으로 발휘할 수 있는 장점이 있는 것이다.As described above, the insect repellent patch of the present invention may express the repellent effect at a desired time because the extract oil is protected by the polymer wall material, and the friction or contact between the microcapsules is applied by applying pressure to the pad part in which the capsule is impregnated. By releasing the internal repellent by the drug has the advantage that can continue to exert the effect.

상기와 같이 본 발명은 해충기피용 마이크로캡슐을 패드에 침지 및 스프레이 또는 나이프캐스팅 등의 방법에 의해 도포하여 해충기피용 패취를 구성하고, 캡슐내부에 충전되는 해충기피제를 천연 추출물 오일을 내부물질로 하고 이러한 약물의 안정성을 유지시키기 위해 고분자 물질로 약물의 표면을 화학적 및 물리적인 방법으로 코팅하므로서, 유통시 약물의 손실을 막고, 효과를 지속적으로 유지할 수 있도록 함은 물론, 피부의 자극과 유독한 냄새를 제거할 수 있어 보다 효과적인 사용이 가능한 것이다.As described above, the present invention constitutes a pest repellent patch by applying a method such as dipping and spraying or spraying or knife casting a microcapsule to a pad, and a natural repellent repellent filled with a capsule as a natural extract oil. In order to maintain the stability of these drugs, the surface of the drug is coated with chemical and physical methods to prevent the loss of the drug in distribution and to maintain the effect, as well as irritating and toxic of the skin. The odor can be removed, making it more effective to use.
