摘　　要：作为造纸填料的二氧化钛(TiO2)价格昂贵,为降低生产成本,着重研究了纳米硫酸钡复合材料部分替代TiO2作为填料和涂布颜料对纸张物理性能的影响。结果表明,添加一定量的纳米硫酸钡复合材料有助于TiO2的分散;当纳米硫酸钡复合材料作为浆内添加填料时,在替代量为0~16%的变化范围内,纸张的物理性能得到改善,替代量为6%时,纸张的白度提升至89.0%,不透明度达到96.5%;当纳米硫酸钡复合材料作为涂布颜料时,随着涂布量的增加,纸张油墨吸收性呈现增长的趋势,L*ab值中b*值逐渐减小,纸张抗蓝光能力显著增强。Due to the high price of titanium dioxide,this work focused on the effect of nano-baritite composites material partly replaced tita⁃nium dioxide as filler and coating pigment on the physical properties of paper to reduce the production cost.The results showed that the addi⁃tion of nano-baritite composites material was helpful to the dispersion of titanium dioxide.In addition,the physical properties of the paper were improved when the substitution amount of nano-baritite composites material in the range of 0~16%.Particularly,the whiteness of paper was increased to 89.0%and the opacity improved to 96.5%with the substitution amount of nano-baritite composites material of 6%.When the nano-baritite composites material was used as coating pigment,with the increase of the coating amount of nano-baritite composites materi⁃al,the paper ink absorption showed increased,and the b*value in L*ab value gradually decreased,indicating the blue light resistance of the paper increased significantly.
