Abstract

The mechanical properties of NATM resin were measured by SEM, FT-IR spectra, tensile properties, mole ％ of [NCO/OH], and particle size analyzer on stainless steel. Growing concerns in the environment-friendly NATM resin, we have synthesized the solvent-free NATM resin to be coating on metals such as stainless. The properties of the synthesized NATM resin to be contained polyols, MDI, silicone surfactant, fillers and crosslink agents(diethyltoluene diamine, anhydrosorbitol), that they have highly stronger in intensity and longer durability than general NATM resin to be contained polyols, IPDI, silicone surfactant, fillers in general packing materials and coatings. The rigid segments of polyurethane in mechanical properties of coatings were due to cross linkage and the increase mole % of [NCO/OH]. In conclusion, the NATM microstructure with cross linkage can be good material for coating of anticorrosion of metal substrates such as stainless steel.

합성된 스테인레스 스틸에 대한 NATM(New Austria Tunnel Method) 수지의 기계적 특성은 SEM, FT-IR, 인장특성, 그리고 [NCO]/[OH]의 mole %, 입도분석에 의해 측정하였다. 친환경적인 NATM에 관한 관심이 고조됨에 따라 스테인레스 등의 금속에 코팅하는 무용제 도료를 합성하였다. 폴리올, IPDI, 충진제, 실리콘 계면활성제, 촉매 등이 함유된 기존 NATM수지보다 폴리올, MDI, 충진제, 실리콘 계면활성제, 촉매, 가교제가 함유되어 합성된 NATM 수지의 도료가 내구력과 강도가 양호하였다. 견고한 NATM 수지의 기계적 특성은 가교와 [NCO]/[OH]의 mole%가 증가함에 따라 강도가 증가하였다. 결론적으로 NATM의 가교된 미세조직는 스테인레스 스틸 같은 금속물질 코팅에 좋은 물질이다.
