摘要：为进一步拓展木塑复合材料应用领域,提高其使用安全性,研究3种阻燃剂对聚乙烯（PE）基木塑地板燃烧性能和力学性能的影响。结果表明：添加阻燃剂后,木塑地板其24.0 h吸水率、弯曲破坏载荷和烟密度等级都达到GB/T 24508-2009《木塑地板》和GB 8624-2006《建筑材料及制品燃烧性能分级》的要求;与对照试件相比较,木塑地板的氧指数提高了25.2%-34.4%,吸水率提高了47.0%-152.0%,弯曲破坏载荷降低了10.5%-27.4%;其中添加阻燃剂FR-C的氧指数和弯曲破坏载荷最大,添加阻燃剂FR-B的烟密度等级和24.0 h吸水率最小。总的来说,添加阻燃剂可以有效提高木塑地板阻燃性,但对板材的物理力学性能有不利影响。同时烟气是火灾中致死的主要原因,木塑地板的产烟毒性有待进一步研究。
To improve application of wood-plastic composites（WPC）, a new type of environmental material, and to promote safety, the effects of three kinds of flame retardants（A, B, and C） on mechanical properties and combustion performance of PE wood plastic composite flooring were compared to unprocessed wood plastic composite flooring and analyzed. Results showed that after adding flame retardants, the 24 h water absorption rate, the bending failure load, and the smoke density of WPC flooring met the GB/T 24508-2009 and GB8624-2006 standards. Compared to unprocessed WPC flooring, the oxygen index increased from 25.2% to34.4%, the 24 h water absorption rate increased from 47.0% to 152.0%, and the bending failure load decreased from 10.5% to 27.4%. Retardant C had the maximum oxygen index and bending failure load for treated WPC flooring; retardant B had the minimum 24 h water absorption rate and smoke density. Overall, flame retardants improved the flame retardation properties of WPC flooring but negatively influenced mechanical properties;meanwhile, smoke from fire with WPC flooring was the main cause of casualties, so this toxic smoke requires further study.
