摘　　要： 研究了共沉淀法合成镁铝类水滑石,并通过纤维填充的方法应用到纸张阻燃中,探讨了镁铝类水滑石的晶体性质及纸张阻燃性能。结果表明:合成的镁铝类水滑石胶体颗粒的体积平均粒径为112nm,晶体结晶度较高,热稳定性好;颗粒带有较高正电荷和高比表面积,应用于阻燃纸时可起到加填、增白、阻燃及微粒助留的作用。当水滑石用量为10%时,阻燃纸的氧指数为25%,具有很好的阻燃效果。 The feasibility and technological conditions of the preparation of flame retardant paper based on the fibers in which Mg-Al hydrotalcites were co-precipitated as the filler were investigated. The crystallizations, granularities of Mg-Al and the characters of the flame retardant paper were measured using transmission election microscope and X-ray diffraction technique, etc. The results indicated that Mg-A1 hydrotalcites are layered hexagonal nanoparticles, with perfectly crystallized structure and striking performance in furnish retention improvement. The flame retardant paper based on the fibers in which the Mg-Al hydrotalcites are precipitated as fillers is feasible. The oxygen index of the flame retardant paper produced is above 20% at the dosaee of 10% of the hvdrotalcites.
