Combustive properties of specimens treated with methylenepiperazinomethyl-Bis-phosphonic acid (Mn+)s

초록

This study was performed to test the combustive properties of pinus rigida specimens treated with methylpiper azinomethyl-bis-phosphonic acid Mn+ (PIPEABPMn+)s and methylpiperazinomethyl-bis-phosphonic acid (PIPEABP). Each pinus rigida plates were painted three times with 15 wt% PIPEABPMn+s or PIPEABP solutions at the room temperature. After drying specimens treated with chemicals, combustive properties were examined by the cone calorimeter (ISO 5660-1). It was indicated that the speed to peak mass loss rate (MLR peak), (0.104~0.121) g/s for specimens treated with PIPEABPMn+s was lower than that of PIPEABP plate. In addition, the total smoke release rate (TSRR), (224.4~484.0) m2/m2 for PIPEABPMn+s treated specimens except specimen treated with PIPEABPAl3+ and CO mean production (0.0537~0.0628) kg/kg was smaller than that of PIPEABP plate. In particular, for the specimens treated with PIPEABPMn+ by reducing the smoke production rate, the second -smoke production rate (2nd-SPR) (0.0117~0.0146) m2/s was lower than that of PIPEABP plate. It can thus be concluded that combustion-retardation properties of the treated PIPEABPMn+s were partially improved compared to those of the virgin plate. © 2014 The Korean Society of Industrial and Engineering Chemistry.
