摘要
通过调节涂料配方中CMC的用量,检测其对涂料及涂布纸性能的影响。结果表明,在一定范围内,CMC用量增加,涂料形成的网状结构更强固,涂料黏度增加,触变性增加,保水性更好;CMC/胶乳涂料体系中,CMC用量增加对涂布纸的涂层结构有一定的影响,粗糙度增加,光泽度下降,印刷光泽度有先增加、后下降的趋势,白度增加,对表面强度影响较小。
The influences of CMC content on the properties of coating color and coated paper were tested by regulating CMC content in coating color formulation. The results showed that as the CMC content increases in a certain range, the network structure of coating color becomes stronger. Consequently, the coating color has a larger viscosity, higher rheopexy and better water retention properties. In CMC/SB latex coating color system, the CMC content affects the coating layer structure of coated paper： When the CMC content is increased, the paper roughness and brightness are improved, the gloss is lowered, and the printing gloss is firstly increased then, decreased while the surface strength of coated paper does not change remarkably.
