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. |
