摘　　要：涂料的流变性能是影响涂布加工纸质量的重要因素之一,对涂布加工过程中涂层的均匀性以及获得良好的涂层性能具有决定性影响.本实验针对涂布白板纸涂料进行了研究,通过添加大豆蛋白改善涂料的流变性能及涂层的表面性能.结果表明,大豆蛋白使涂料低剪切粘度增加,剪切稀化作用增大,改善了涂料的触变性能,并且使涂布白板纸表面粗糙度下降、适印性能提高,同时涂层的表面强度也有一定的提高.The rheological properties of paper coatings is one of the important influencing factors of coated paper quality,it has a decisive influence on how to uniformly coat on paper and achieve well coat layer.In this paper,the coatings of coated white paperboard was studied by the addition of soy protein to improve the rheological properties and the surface properties of coating layer.The results show that the soy protein made higher apparent viscosity of coating,increased the shear-thinning action and improve the rheological properties,at the same time,the smoothness and printability were improved,the surface strength of coated paper had a certain increasing.
