Evaluation of Combustion Gas for Carbon Oxide of Wood Coated with Bis-(dialkylaminoalkyl) Phosphinic Acids Additives

Abstract

요 약 이 연구는 비스-(디메틸아미노메틸) 포스핀산(DMDAP), 비스-(디에틸아미노메틸) 포스핀산(DEDAP) 과 비스-(디부틸 아미노메틸) ABSTRACTThis study examined the generation of combustion toxic gases of pinus rigida specimens processed with bis-(dimethylaminomethyl) phosphinic acid (DMDAP), bis-(diethylaminomethyl) phosphinic acid (DEDAP), and bis-(dibutylaminomethyl) phosphinic acid (DBDAP). Each pinus rigida plate was coated three times with 15 wt.% flame retardants in an aqueous solution. The specimens were then dried at room temperature. The production of combustion toxic gases was investigated using a cone calorimeter (ISO 5660-1). The first time to peak mass loss rate (1 ) for the processed specimens was decreased 1.8% for DMDAP and 5.3% for DBDAP and increased 1.8% for DEDAP. The peak carbon monoxide (CO p e a k ) production was 1.5 to 2.0 times higher than that of the unprocessed plate. The peak carbon dioxide (CO 2 p e a k ) production was reduced 0.01 times for DMDAP and increased 1.15 to 1.19 times for DEDAP and DBDAP compared with the unprocessed specimens. In particular, the oxygen concentration was much higher than 15%, which can be fatal to humans and the resulting hazard can be eliminated. Overall, the combustion toxicity of flammable gas were increased partially by the chemical additives compared with those of the unprocessed plate.
