ASD阻燃剂对落叶松材阻燃性能的影响
Effect of ASD flame retardant on fire-retardant efficiency of larch wood
摘要
Abstract
ASD flame retardants with different mass ratios were applied to larch wood in a vacuum condition in order to manufacture structural glulam with good fire-retardant property.The cone calorimeter test and thermogravimetric (TG) analysis were used to examine the fire-retardant effect of samples and determine the optimal ASD mass ratio.The results showed that the total heat release (THR) and total smoke release (TSR) of larch significantly decreased after the ASD fire-retardant treatment,and the fire-retardant performance improved with the increase of ASD flame retardant content.The yield of CO also increased with the increased content of ASD flame retardant,while the yield of CO2 decreased.Furthermore,the total yield of CO and CO2 decreased significantly,indicating that the fire-retardant treatment of ASD significantly inhibited the combustion of larch.When considering the fire-retardant effect and the cost,50％ was the optimal mass ratio of ASD flame retardant.The THR and TSR of the treated larch wood decreased by 56.46％ and 88.20％,respectively,compared with those of the untreated larch wood.The mass ratio of the residual carbon increased from 18.26％ to 41.06％,and the initial decomposition temperature of larch decreased after treated with ASD flame retardant.The results of cone calorimeter test showed that the surface morphology of the larch treated with ASD flame retardant was different from that of the untreated larch.The wood charcoal of larch surface without ASD flame retardant treatment was soft and had large fault after the cone calorimeter test,while that of the larch treated with ASD flame retardant was dense,which can delay the burning effectively.The effect of ASD flame retardant is mainly attributed to the catalytic effect of char forming.关键词
