摘　　要：本研究将磷酸化纳米纤维化纤维素(PMFC)与水性聚氨酯(WPU)混合,然后分别引入氢氧化镁颗粒和纳米铜粒子制备阻燃、耐磨复合材料,并对复合材料的显微结构、颗粒分散性能、热稳定性能、阻燃性能、耐磨性能等进行了考察。结果表明:氢氧化镁颗粒和纳米铜粒子的添加量对复合材料的显微结构影响较大;在水性聚氨酯涂料中添加一定量的磷酸化的纳米纤维素、氢氧化镁颗粒和纳米铜粒子能够提高复合材料的阻燃性和耐磨性,应用于木质板材上时,可使木质板材获得更好的表面性能。In this study,phosphorylated nanofibrotic cellulose(PMFC)was mixed with waterborne polyurethane(WPU),and then magnesium hydroxide particles and copper nanoparticles were introduced to prepare flame retardant and wear-resistant composites.The microstructure,particle dispersion,thermal stability,flame retardant properties,and wear-resisting property of the composites were characterized.The results showed that the addition amount of magnesium hydroxide particles and copper nanoparticles had a significant impact on the microstructure of the composites.After the addition of phosphorylated nanocellulose,magnesium hydroxide particles,and copper nanoparticles into waterborne polyurethane coatings,the flame retardancy and wear resistance of the composites improved.When applied to the wood board,it could impart wood board with better flame-retardant and wear-resistant properties.
