酸源与气源配比对膨胀阻燃剂炭层形成和阻燃性能的影响
Effect of acid and gas source ratio on char layer formation and flame retardancy of the intumescent flame retardant
[目的]为探究酸源与气源比例与膨胀型阻燃剂阻燃效果之间的关系,并分析其对阻燃处理杨木燃烧特性的影响。[方法]选用植酸和尿素分别作为酸源和气源,制备比例为 1:3、1:6、1:10、1:12 的膨胀型阻燃剂,即PAN-3、PAN-6、PAN-10、PAN-12 膨胀型阻燃剂,并采用全自动元素分析仪验证分析上述 4 种阻燃剂中 N 元素与 P 元素的比例。采用真空浸渍法获得阻燃处理杨木试样,借助热重(TGA)、锥形量热(CONE)分析其化学组分变化以…查看全部>>
[Objective]This study aims to investigate the correlation between the acid and gas source ratio and the flame retardant effect of intumescent flame retardants(IFR),and analyze their impact on the combustion characteristics of flame-retardant-treated poplar wood(FW).[Method]Phytic acid and urea were selected as acid source and gas source,respectively.IFRs with different ratios(1:3,1:6,1:10,and 1:12)were prepared and labeled as PAN-3,PAN-6,PAN-10,and PAN-12.Th…查看全部>>
