초록
이 연구에서는 피페라지노메틸-비스-포스폰산(PIPEABP), 메틸피페라지노메틸-비스-포스폰산(MPIPEABP), N,N-디메틸렌디아미노메틸-비스-포스폰산(MDEDAP) 그리고 비스-디메틸아미노메틸 포스핀산(DMDAP)의 화학 첨가제로 처리된 중질섬유판(MDF)의 연소가스 발생을 시험하였다. 15 wt%의 인-질소산류 첨가제 수용액으로 중질섬유판에 붓으로 3회 칠하여 실온에서 건조시킨 후, 콘칼로리미터(Conecalorimeter, ISO 5660-1, 2)를 이용하여 연소가스의 발생을 시험하였다. 그 결과, 인-질소산류 첨가제로 처리한 시험편의 최대연기발생률(SPRpeak)은 무처리 시험편에 비교하여 18.5~41.5%로 낮게 나타내었다. 그러나 인-질소산류 첨가제로 처리한 시험편에 대한 최대일산화탄소 생성(COpeak), (6.7~24.2)%은 공시험편보다 높게 나타났다. 또한 최대이산화탄소 발생(CO2peak), (4.2~24.4)%은 공시험편보다 낮게 나타났다. 반면에 O2의 최대결핍률은 사람에게 치명적일 수 있는 수준인 15%보다 훨씬 높으므로 그로 인한 위험성은 피할 수 있었다. 결론적으로 MDF에 인-질소산류로 처리한 시험편은 부분적으로 연소성이 억제되었다. 그러나 일산화탄소의 감소에는 부정적인 영향을 미쳤다.
This study demonstrated the emission of combustion gases of medium density fibreboard (MDF)s coated with piperazinomethyl-bis-phosphonic acid (PIPEABP), methylpiperazinomethyl-bis-phosphonic acid (MPIPEABP), N,N-dimethylethylenediaminomethyl-bis-phosphonic acid (MDEDAP), or bis-(dimethylaminomethyl) phosphinic acid (DMDAP). Each MDFs were coated in three times with a brush with 15 wt% aqueous solution of the phosphorus-nitrogen acid additives. After the specimens were dried at room temperature, the emission of combustion gases was tested using a cone calorimeter (ISO 5660-1, 2). The peak smoke production rate (SPRpeak) of the specimens coated with phosphorus-nitrogen acids was 18.5 to 41.5%, which is lower than that of using the virgin plate. However, the production of peak carbon monoxide (COpeak) was 6.7 to 24.2% higher than that of using the virgin plate. Also, the peak carbon dioxide (CO2peak) was 4.2 to 24.4% lower than that of using virgin plate. While the peak oxygen depletion rate was much higher than the level of 15%, which can be fatal to humans and the resulting risk could thus be eliminated. Overall, the combustibility of coated specimens was partially suppressed, but showed a negative effect on the reduction of carbon monoxide.
