이 연구에서는 메틸렌피페라지노메틸-비스-포스폰산 금속염($PIPEABPM^{n+}$)과 메틸렌피페라지노메틸-비스-포스폰산(PIPEABP) 으로 처리된 리기다 소나무의 연소성을 시험하였다. 15 wt%의 메틸렌피페라지노메틸-비스-포스폰산 금속염과 메틸렌피페라지노메틸-비스-포스폰산 수용액으로 각각 리기다 소나무에 3회 붓칠하여 실온에서 건조시킨 후, 콘칼로리미터(ISO 5660-1)를 이용하여 그의 연소성을 시험하였다. 그 결과, 메틸렌피페라지노메틸-비스-포스폰산 금속염으로 처리한 시험편은 메틸렌피페라지노메틸-비스-포스폰산을 처리한 시험편에 비해 최대질량감소율($MLR_{peak}$)이 (0.104~0.121) g/s으로 낮았다. 그리고 그의 금속염으로 처리한 시험편($PIPEABPM^{n+}$)은 금속염으로 처리하지 않은 시험편(PIPEABP)보다 낮은 총연기발생률(TSRR), (224.4~484.0) $m^2/m^2$과 낮은 $CO_{mean}$ (0.0537~0.0628) kg/kg 값을 보였다. 특별히 2차 연기발생속도(2nd-SPR)는 메틸렌피페라지노메틸-비스-포스폰산 니켈염($PIPEABPNi^{2+}$)으로 처리한 시험편을 제외하고, 금속염 처리 시험편($PIPEABPM^{n+}$)은 (0.0117~0.0146) g/s으로서 금속염으로 처리하지 않은 시험편(PIPEABP)에 비하여 낮았다. 따라서 메틸렌피페라지노메틸-비스-포스폰산 금속염으로 처리한 시험편은 처리하지 않은 시험편에 비하여 그의 연소 억제성을 부분적으로 향상시켰다. |

This study was performed to test the combustive properties of pinus rigida specimens treated with methylpiperazinomethyl-bis-phosphonic acid $M^{n+}$ ($PIPEABPM^{n+}$)s and methylpiperazinomethyl-bis-phosphonic acid (PIPEABP). Pinus rigida Plates were painted in three times with 15 wt% $PIPEABPM^{n+}s$ and PIPEABP solutions 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 $PIPEABPM^{n+}s$ showed the lower speed to peak mass loss rate ($MLR_{peak}$), (0.104~0.121) g/s than that of PIPEABP plate. In adition, the specimens treated with $PIPEABPM^{n+}s$ showed both the lower total smoke release rate (TSRR), (224.4~484.0) $m^2/m^2$ and $CO_{mean}$ production (0.0537~0.0628) kg/kg than those of PIPEAB plate. Especially, for the specimens treated with $PIPEABPM^{n+}$ by reducing the smoke production rate except 2nd-smoke production rate (2nd-SPR), (0.0254~0.02270) g/s treated with $PIPEABPNi^{2+}$, 2nd-SPR (0.0117~0.0146) g/s was lower than that of PIPEABP plate. Thus, It is supposed that the combustion-retardation properties were improved by the partial due to the treated $PIPEABPM^{n+}s$ in the virgin plate. |
