요약

이 연구에서는 비스-디메틸아미노메틸 포스핀산, 비스-디에틸아미노메틸 포스핀산, 비스-디부틸아미노메틸 포스핀산을 처리한 리기다 소나무의 연소성을 시험하였다. 시험편은 15 wt%의 비스-디알킬아미노알킬 포스핀산 수용액으로 리기다 소나무에 3회 붓칠하여 실온에서 건조시킨 후, 콘칼로리미터(ISO 5660-1)를 이용하여 그의 연소성을 시험하였다. 그 결과, 비스-디알킬아미노알킬 포스핀산으로 처리한 시험편은 처리하지 않은 시험편에 비하여 그의 연소 억제성을 부분적으로 향상시켰다. 비스-디알킬아미노알킬 포스핀산으로 처리한 시험편은 무처리한 시험편에 비해 총연기방출률($16.94{sim}18.92m^2/m^2$)과 $CO_{2mean}$ 발생량(1.98~2.09 kg/kg)을 감소시켰다. 그러나 무처리한 시험편에 비해 최대질량감소율($16.94{sim}18.92m^2/m^2$)과 1차-연기발생속도(0.0153~0.0167 g/s)를 증가시켰다. 따라서 비스-디알킬아미노알킬 포스핀산으로 처리한 시험편은 순수 리기다 소나무 시험편에 비하여 부분적으로 낮은 연소성질을 나타내었다.

Abstract

This study was performed to test the combustive properties of Pinus rigida plates treated with bis-(dimethylaminomethyl) phosphinic acid (DMDAP), bis-(diethylaminomethyl) phosphinic acid (DEDAP), and bis-(dibuthylaminomethyl) phosphinic acid (DBDAP). Pinus rigida specimens were painted in three times with 15 wt% bis-(dialkylaminoalkyl) phosphinic acid solutions at the room temperature. After drying specimen treated with chemicals, combustive properties were examined by the cone calorimeter (ISO 5660-1). It is supposed that the combustion-retardation properties were improved by the partial due to the treated bis-(dialkylaminoalkyl) phosphinic acids in the virgin Pinus rigida. Especially, the specimens treated with chemicals showed both the lower total smoke release rate (TSRR) ($16.94{sim}18.92m^2/m^2$) and lower $CO_{2mean}$ production (1.98~2.09 kg/kg) than those of virgin plate. However the specimens treated with chemicals showed both the higher peak mass loss rate (PMLR) (0.1250~0.1297 g/s) and higher 1st-smoke production rate (SPR) (0.0153~0.0167 g/s) than those of virgin plate. Compared with virgin Pinus rigida plate, the specimens treated with the bis-dialkylamimoalkyl phosphinic acids showed partially low combustive properties.
