초록

본 연구에서는 메틸렌피페라지노메틸-비스-포스폰산 금속염($PIPEABPM^{n+}$)과 메틸렌피페라지노메틸-비스-포스폰산(PIPEABP)으로 처리된 리기다 소나무의 연소독성가스의 생성을 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 연소독성가스의 생성을 시험하였다. 그 결과, 메틸렌피페라지노메틸-비스-포스폰산 금속염으로 처리한 시험편은 메틸렌피페라지노메틸-비스-포스폰산 철염($PIPEABPFe^{2+}$)으로 처리한 시험편을 제외하고, 메틸렌피페라지노메틸-비스-포스폰산을 처리한 시험편과 비교하여 최대일산화탄소의 생성($CO_{peak}$ production)이 (0.0136~0.0178% at 532~678 s)으로 낮게 나타났다. 그리고 금속염으로 처리한 시험편($PIPEABPM^{n+}$)은 금속염으로 처리하지 않은 시험편(PIPEABP)보다 낮은 최대이산화탄소의 생성($CO_{2\;peak}$ production)이 (0.0537~0.0628% at 532~678 s)임을 보였다. $O_2$의 생성농도는 사람에게 치명적일 수 있는 수준인 15%보다는 훨씬 높으므로 그로 인한 위험성은 배제할 수 있었다. 따라서 메틸렌피페라지노메틸-비스-포스폰산 금속염으로 처리한 시험편은 처리 하지 않은 시험편과 비교하여 연소-유독성을 부분적으로 감소시켰다.

This study was performed to test the production of combustion toxic gases by Pinus rigida specimens treated with various types of methylpiperazinomethyl-bis-phosphonic acid $M^{n+}$ ($PIPEABPM^{n+}$) and methylpiperazinomethyl-bis-phosphonic acid (PIPEABP). Three coats of 15 wt% $PIPEABPM^{n+}$ and PIPEABP solutions were applied to plates of Pinus rigida at room temperature. After drying the treated specimens, the production of combustion toxic gases was examined using a cone calorimeter (ISO 5660-1). The specimens treated with $PIPEABPM^{n+}$ showed lower carbon monoxide production ($CO_{2\;peak}$; 0.0136~0.0178% at 532~678 s) than the PIPEABP plates, except for the specimen treated with $PIPEABPFe^{3+}$. In addition, the peak carbon dioxide production ($CO_{2\;peak}$) was lower (0.03648~0.3648% at 373~433 s) than that of the PIPEABP-treated plate. Notably, oxygen production was much higher than 15%, which can be fatal to humans. Therefore, the resulting risk could be eliminated. The results indicate that the combustion toxicities were partially decreased due to treatment of the virgin plate with $PIPEABPM^{n+}$.
