Abstract

The microstructures of NATM were examined by SEM, FT-IR spectra, tensile properties, mole % of [NCO/OH], and particle size analyzer. Growing concerns in the environment-friendly industries have led to the development of solvent-free formulations that can be cured. We had synthesized NATM(New Austria Tunnel Method) resin having the ability to protect stainless steel against corrosion. Comparing with general NATM resin and coatings, this resin that synthesized with polyurethane and epoxy was highly stronger in intensity and longer durability. Hybrid resin was composed of polyols, MDI, epoxy, silicone surfactant, catalyst and crosslink agent, and fillers. Moreover, fillers such as fume silica not only accelerated the curing rate but also improved the physical property as thermal barriers. The rigid segments of synthetic resin in mechanical properties were due to fume silica and the increase the mole% of [NCO/OH] for corrosion protection. In conclusion, the hybrid resin microstructure with crosslink agent and fume silica are good material for thermosetting coating of metal substrates such as stainless steel.

NATM의 미세 구조는 SEM, FT-IR, 인장특성, 그리고 [NCO]/[OH]의 mole %, 입도분석에 의해 측정하였다. 친환경적인 NATM에 관한 관심이 고조됨에 따라 스테인레스 등의 금속코팅에 더욱더 중요한 무용제 도료의 발전을 이끈다. 우리는 스테인레스 스틸의 부식을 방지할 수 있는 NATM(New Austria Tunnel Method)의 수지를 합성하였다. 폴리우레탄과 에폭시로 합성한 혼성 수지는 일반적 NATM 수지와 도료와 비교하여 강도와 내구력이 매우 양호하다. 혼성수지는 폴리올, 에폭시, MDI, 실리콘 계면활성제, 촉매, 가교제, 충전제로 구성된다. 충전제인 fume silica는 경화속도를 가속시킬 뿐만 아니라 열적 장벽으로 물성이 우수함을 나타냈다. NATM 수지의 기계적 특성은 [NCO]/[OH]의 mole%와 fume silica가 증가함에 따라 강도가 증가하였다. 결론적으로 가교제와 fume silica가 함유된 혼성수지의 미세구조는 스테인레스 스틸같은 금속물질의 열경화코팅을 위한 좋은 물질이다.
