본 발명은 내한,내열성능을 극대화할수 있는 인쇄회로기판용 절연,방습,씰링 보호코팅제 조성방법에 관한 것으로서, 좀더 상세하게 설명하면 실외에 설치되어지는 태양발전식 자동발광 안전유도등에 사용되어지는 충진재로 여름철에는 고내열성을 지니며 겨울철에는 고내한 성능을 발휘하여 제품이 정상적이고 안정적으로 작동할수 있게 해주는 인쇄회로기판(PCB)용 절연,방습,씰링 보호코팅제의 조성방법에 관한 것이다.The present invention relates to a method of forming an insulation, moisture-proof, and sealing protective coating composition for printed circuit boards capable of maximizing resistance to cold and heat, and more particularly, to a method for preparing a filler Humidity and sealing protective coatings for printed circuit boards (PCBs), which have high heat resistance in summer and high performance in winter, so that products can operate normally and stably.
최근 건강에 대한 관심이 증대되면서 걷기길 이나 자전거도로등을 설치하는 경향이 늘어나고 있으며,수변공원이나 생태공원등 체험학습장으로써의 시설물들이 확대설치되어 지고 있는 가운데 야간 안전을 위해 전선매립방식이 아닌 태양발전식 자동발광 안전유도등의 설치가 늘어나는 추세이다.In recent years, as the interest in health has increased, the tendency to install walking paths and bicycle roads has been increasing, and facilities such as waterside parks and eco parks have been expanded and installed. In addition, There is an increasing tendency for the installation of automatic lighting emission guidance lamps.
그러나 지금까지 야외에 설치되어지는 태양발전식 자동발광 안전유도등엔 제조사나 제조인의 노하우 공개를 꺼러 작동을 제어하는 핵심 인쇄회로기판에 에폭시로 도포하여 분해가 용이치 않게 하는 정도로 제작하여 설치하고 있으며 야외 환경에서 발생하는 계절적인 영향이나 기후(강우,일교차 등)에 따른 제품에 영향을 미치는 요인에 대하여는 고려되고 있지 않은 실정이다. 이러한 내용에 관하여 국내 공개특허공보(A) 공개번호 10-2011-0137727(2011.12.23일 공개) LED 조명기의 PCB기판용 에폭시 조성물 및 이의 제조방법에 게시되어 있다. 본원 발명의 발명가는 상기의 문제를 해결하기 위하여 본원 발명을 발명하였다.However, until now, the solar-powered automatic emission safety guiding light installed in the outdoor has been manufactured and installed to the extent that it is applied by epoxy to the core printed circuit board which controls the operation against the disclosure of the know-how of the manufacturer or the manufacturer, The seasonal influences in the outdoor environment and the factors affecting the products due to the climate (rainfall, daily drift, etc.) have not been considered. This publication is disclosed in Korean Patent Publication (A) Publication No. 10-2011-0137727 (published on December 23, 2011), an epoxy composition for a PCB substrate of an LED illuminator, and a manufacturing method thereof. The inventor of the present invention invented the present invention in order to solve the above problems.
따라서 이러한 태양발전식 자동발광 안전유도등의 주요구성품인 인쇄회로기판과 이차전지의 사용온도(영상50도 ~영하20도)의 제한등에 의해 여름철 고온과 장마,습기등과겨울철 저온 및 결로등에 의해 상당수가 이상작동을 일으키고 있어서 여름철 고온에 견디는 내열성(85도에서 72시간후 이상없음)과 방습,절연(IP67에서 적합)성능을 지니며 겨울철엔 내한성능(영하60도에서 72시간후 이상없음)이 발휘되어 이상없이 정상작동 되어야 한다.Therefore, due to the limitation of the usage temperature (50 degrees to minus 20 degrees) of the printed circuit board and the secondary battery, which are the main components of such a solar powered automatic light emitting safety guide light, a considerable number It has the heat resistance (no more than 72 hours after 85 degrees) and the moisture proof and insulation (suitable for IP67) in the summer due to the abnormal operation, and the cold resistance performance in winter (no more than 72 hours at minus 60 degrees) It should be normal operation without abnormality.
상기와 같은 목적을 달성하기 위하여 본 발명은 폴리우레탄을 주제와 경화제로 나누어 구성성분별 함유량을 적합하게 조절하여 충진재로 사용한다.In order to achieve the above object, the present invention uses polyurethane as a filler by appropriately controlling the content of each component by dividing the polyurethane into a main component and a hardener.
상술한 바와 같이 본 발명은 인쇄회로기판과 이차전지를 포함한 제품내부에 충진하여 계절별 기온,기후변화에 적절히 대응하는 성능을 지녀 제품이 안정적이며 정상적으로 작동할수 있도록 해주는 매우 유용한 발명인 것이다.As described above, the present invention is a very useful invention that enables the product to be stably and normally operated by filling the product including the printed circuit board and the secondary battery and having the ability to appropriately cope with seasonal temperature and climate change.
