摘要：以聚乙烯(PE)、橡胶木木粉、氢氧化铝制备阻燃型木塑地板。通过测试物理力学性能和燃烧性能,研究了纳米氢氧化铝添加量、纳米氢氧化铝与非纳米氢氧化铝配比对木塑地板24 h吸水率、弯曲破坏载荷、氧指数、烟密度等级的影响。结果表明,当纳米氢氧化铝的质量分数从5%增加到15%时,木塑地板24 h吸水率降低23.2%、弯曲破坏载荷呈先增加后减小的趋势、氧指数上升16.69%、烟密度等级呈先减小后增加的趋势;随着纳米氢氧化铝与非纳米氢氧化铝配比的增加,木塑地板24 h吸水率降低28.6%、弯曲破坏载荷增加4.5%、氧指数上升8.5%、烟密度等级下降19.5%。
The flame-retardant wood plastic composites flooring were prepared by using polyethylene（PE） and rubber wood powder and aluminum hydroxide.The effects of the addition of the nano-aluminum hydroxide and the ratio of the nano-aluminum hydroxide with non nano-aluminum hydroxide on 24 h water absorption,the bending failure load,oxygen index and smoke density of PE wood plastic composites flooring were analyzed by testing mechanical properties and combustion performances.The results showed that： with the addition of the nano-aluminum hydroxide from 5% to 15%,the 24 h water absorption rate decreased by23.2%,the bending failure load manifested upward first and then downward,the oxygen index increased by16.69%,the smoke density manifested downward first and then upward.With the ratio increasing of the nano-aluminum hydroxide with non nano-aluminum hydroxide,the 24 h water absorption rate decreased by28.6%,the bending failure load increased by 4.5%,the oxygen index increased by 8.5%,the smoke density decreased by 19.5%.
