Abstract
항공기 산업에서 착빙 제거 및 방지는 안전상 매우 중요한 기술이다. 착빙 제거에 대한 연구는 활발히 진행되어 실제 항공기에 적용한 상태이지만, 착빙을 사전에 방지 및 지연하는 기술은 아직미비한 실정이다. 본 연구에서는 다른 종류의 나노입자를 코팅함으로써 폴리우레탄 탑코트의 표면거칠기 및 표면에너지를 조절하였다. 각 나노입자 종류에 따른 코팅면에 증류수를 이용한 정적접촉각을측정하여 소수성을 평가하였고, 나노입자 코팅면의 안정도를 평가하기 위해 인발접착시험을 진행하였다. 또한, 나노입자의 종류에 따른 탑코트의 색재현성 평가를 위해 표면의 RGB 색을 비교하여 정량화를 진행하였다. 이를 통해 탑코트의 원색을 최대한 재현하면서 접착성을 가질 수 있는 최적의 소수성표면을 얻을 수 있었다.
In the aircraft industry, anti- and de-icing are one of very important techniques for the safety. The anti-icing technique had not been studied while de-icing technique had been not only researched enough but applied to aircraft industry. In this work, surface roughness and energies of polyurethane (PU) topcoat were controlled with 3 different nanoparticles which was coated to PU topcoat. It was evaluated via static contact angle using distilled water. The adhesion property of 3 nanoparticles was evaluated directly using adhesion pull-off test. The color gamut of nanoparticle coated PU topcoat was also evaluated with 3 different nanoparticles. It was determined using RGB color degree variation between neat PU topcoat and coated nanoparticle. Finally, the optimized nanoparticle was determined to manufacture hydrophobic surface and to maintain color of neat PU topcoat for the aircraft.
