초록

본 연구는 화학보호복 원단들에 대하여 내화학성 및 난연성을 조사하기 위하여 ASTM 및 ISO의 방법을 이용하여 내화학성 및 화재위험성시험을 실시하였다. 시험결과 폴리에틸렌의 경우 전혀 난연성이 없는 것으로 분석되었지만 고무에 데카브롬 등 난연성 물질이 첨가된 불소고무 원단이 뛰어난 난연성을 보였다. 특히 현재 소방용 방열복으로도 사용되고 있는 알루미늄 필름에 아라미드원단을 라미네이팅한 원단이 가장 뛰어난 난연성을 보였다. 하지만 내화학성에 있어 알루미늄은 4% NaOH에 부식되는 결과를 보이고 있어 이를 극복하기 위한 방안으로는 다층의 베리어성 필름을 사용하는 것이 좋을 것으로 사료된다. 아울러 난연성 시험결과 알루미늄필름과 폴리머 베리어성 필름을 소재로 만든 Dual skin과 불소고무에 난연성 물질이 포함된 것을 소재로 만든 Single skin이 화학보호복으로 적합한 것으로 판단된다. 또한 열방호실험과 열전달지수실험결과 두께의 증가와 다층구조일수록 TPP와 HTI 증가하는 것으로 나타났다. 향후 화학 보호복 원단의 화재위험성 및 내화학성시험 등 지속적 연구와 보완이 적절한 화학보호복 원단 성능개선에 기여할 것으로 기대된다.

We have test chemical resistance and flame retardant properties of chemical protective clothing Fabrics by the ASTM and ISO standard methods. The flame retardant test results show that polyethylene is poor in flame resistance but fluoroelastomer add to decabrom is excellent in flame resistance. Especially, nowadays heat protective clothing for firefighters, which is aluminized film layers laminated to aramid fabric, show the excellent flame resistance. However, the chemical resistance test results show that aluminium is high corrosive in 4M NaOH solution alone. The problem of corrosion can be overcome by employing multiple barrier film. Also, based on the result of flame retardant test, duel skin of polymer barrier film add to aluminum film and single skin of fluorinated rubber with flame retardant materials seems to be fit for the chemical protective clothing. Also the thermal protection and heat transfer test results show that TPP and HTI is increased assured that the continued study on fire risk assessment & chemical resistance of chemical protective clothing fabrics will contribute to the upgrade the performances of chemical protective clothing fabrics.
