초록

이 연구에서는 비스-디알킬아미노알킬 포스핀산(DMDAP), N,N-디메틸렌디아미노메틸-비스-포스폰산(DMDEDAP), 피페라지노메틸-비스-포스폰산(PIPEABP), 메틸피페라지노메틸-비스-포스폰산(MPIPEABP)의 화학 첨가제로 처리된 중밀도 섬유판(MDF)의 연소성을 시험하였다. 15 wt%의 화학 첨가제 수용액으로 MDF에 3회 붓칠하여 실온에서 건조시킨 후, 콘칼로리미터(ISO 5660-1), 방염성능 시험(소방방재청 고시 제 2012-34호), 휘발성 유기 화합물측정시험(KS M ISO 11890-2)을 이용하여 그의 연소성을 시험하였다. 그 결과, 비스-디메틸아미노메틸 포스피닉산과 알킬렌디아미노알킬-비스-포스폰산으로 처리한 섬유판은 연소속도 감소에 의하여 무처리한 섬유판에 비해 긴 연소시간 = (442~492) s을 나타내었다. 게다가 탄화면적과 탄화길이는 각각 $(44.33{\sim}61.33)cm^2$와 (10.33~11.67) cm로서 무처리한 시험편보다 높게 측정되었다. 또한 화학 첨가제 수용액으로 처리한 섬유판의 휘발성 유기화합물은 규정 한도내에서 (0.188~0.333) g/L으로 발생하였으며, 무처리한 시험편의 휘발성 유기화합물 보다 높게 나타났다. 따라서 비스-디알킬아미노알킬 포스폰산과 알킬렌디아미노알킬-비스-포스폰산으로 처리된 섬유판은 무처리한 섬유판보다 난연성을 부분적으로 향상시킨 것으로 판단 된다.

This study was performed to test the combustive properties of Medium Density Fibreboards (MDFs) treated with chemicals of the bis-(dimethylaminomethyl) phosphinic acid (DMDAP), N,N-dimethylethylenediaminomethyl-bis-phosphonic acid (DMDEDAP), piperazinomethyl-bis-phosphonic acid (PIPEABP), and methylpiperazinomethyl-bis-phosphonic acid (MPIPEABP). MDFs were painted in three times with 15 wt% solution of the bis-(dimethylaminomethyl) phosphinic acid and alkylenediaminoalkyl-bis-phosphonic acids at the room temperature, respectively. After drying MDF treated with chemicals, combustive properties and volatile organic compounds (VOCs) contents were examined by the cone calorimeter (ISO 5660-1), test for flame retardant (NEMA Notice No. 2012034), and gas chromatography (KS M ISO 11890-2), respectively. It was indicated that the MDFs treated with chemicals showed the longer time to combustion time (CT) = (442~492) s than that of virgin plate by reducing the burning rate except for CT treated with DMDAP. In adition, the MDFs treated with chemicals showed both of the higher char area (44.33~61.33) kg/kg and char length (10.33~11.67) cm than those of virgin plate. Especially, the MDFs treated with chemicals showed the higher mean volatile organic compounds (VOCs) (0.188~0.333) g/L than that of virgin plate within the prescribed limits. Thus, It is supposed that the combustion- retardation properties were improved by the partial due to the treated chemicals in the virgin MDF.
