초록

이 연구에서는 피페라지노메틸-비스-포스폰산(PIPEABP), 메틸피페라지노메틸-비스-포스폰산(MPIPEABP), N,N-디메틸 렌디아미노메틸-비스-포스폰산(MDEDAP), 비스-디알킬아미노알킬 포스폰산(DMDAP)으로 처리된 중밀도섬유판(MDF)의 연소성을 시험하였다. 15 wt%의 알킬렌디아미노알킬-비스-포스폰산 수용액으로 MDF에 3회 붓칠하여 실온에서 건조시킨 후, 콘칼로리미터(ISO 5660-1)를 이용하여 그의 연소성을 시험하였다. 그 결과, 알킬렌디아미노알킬-비스-포스폰산 및 비스-디메틸아미노메틸 포스피닉산(DMDAP)로 처리한 시험편은 연소속도 감소에 의하여 무처리한 시험편에 비해 최대질량감소율 도달시간($TMLR_{peak}$) = (340475) s을 지연시켰다. 게다가 $CO_{mean}$은 (0.0883~0.0963) kg/kg으로서 무처리한 시험편(0.0612 kg/kg)보다 높게 측정되었다. 특별히 화학 첨가제 수용액으로 처리한 시험편의 비소화면적($SEA_{mean}=5m^2/kg{\sim}21.5m^2/kg$)은 무처리한 시험편의 비소화면적($-426.8m^2/kg$) 보다 높았다. 따라서 알킬렌디아미노알킬-비스-포스폰산 및 비스-디알킬아미노알킬 포스폰산으로 처리된 MDF의 시험편은 무처리한 MDF 시험편의 난연성을 향상시킨 것으로 판단된다. 그러나 연기발생량 감소에는 부정적인 영향을 주었다.

This study was performed to test the combustive properties of Medium Density Fibreboard (MDF) specimens treated with piperazinomethyl-bis-phosphonic acid (PIPEABP), methylpiperazinomethyl-bis-phosphonic acid (MPIPEABP), and N,N-dimethylethylenediaminomethyl-bis-phosphonic acid (MDEDAP). MDF Plates were painted in three times with 15 wt% solution of the alkylenediaminoalkyl-bis-phosphonic acids at the room temperature, respectively. After drying specimen treated with chemicals, combustive properties were examined by the cone calorimeter (ISO 5660-1). It was indicated that the specimens treated with chemicals showed the later time to peak mass loss rate ($TMLR_{peak}$) = (340475) s than that of virgin plate by reducing the burning rate. In adition, the specimens treated with chemicals showed the higher $CO_{mean}$ production (0.0883~0.0963) kg/kg than that of virgin plate. Especially, the specimens treated with chemicals showed the higher mean smoke extinction area ($SEA_{mean}$) ($5m^2/kg{\sim}21.5m^2/kg$) than that of virgin plate. Thus, It is supposed that the combustion-retardation properties were improved by the partial due to the treated alkylenediaminoalkyl-bis-phosphonic acids in the virgin MDF Plate. However, It gave a negative effect on smoke reduction.
