摘要

依据美国标准AWPA P50-2010配制三种FR-2型阻燃剂,用于桉树单板的浸渍处理,制备阻燃胶合板。试验结果表明:三种阻燃剂处理的胶合板,均表现出较好的阻燃和抑烟效果,Ⅱ类胶合强度及吸湿性差异不显著。综合考虑各项性能,由磷酸二氢铵、磷酸氢二铵及硼酸配制的阻燃剂,较适用于桉树胶合板的阻燃处理。

Abstract

Three formulations of FR-2 （ phosphorus-nitrogen-boron ） fire retardants were prepared according to the AWPA P50-2010 standard. The three retardants were then used to treat Eucalyptus veneers for plywood. The effects of the fire retardant treatment on fire performance,bonding strength,and hygroscopicity of the plywood samples were evaluated. The results indicated that both fire retardancy and reduced smoke from the plywood were significantly improved after the fire-retardant treatment. Bonding strength and hygroscopic behavior of the samples after the treatment remained the same. We also found that PNB-1 fire retardant,composed of Monoammonium phosphate,Diammonium phosphate and Boric acid was the most suitable for Eucalyptus plywood among the three retardants.
