涂料配方的选择不仅影响涂布纸的性能,还决定涂布纸的最终质量。不同助剂的配比对涂料和纸张性能的影响也不同。本文分别对涂料固含量、保水剂、生物胶乳、分散剂等造纸助剂及纳米粒子对纸张涂料流变性和纸张性能的影响进行单因素分析。在此基础上,选取固含量、分散剂含量、纳米粒子含量进行纸张平滑度的响应面分析,在固含量55%,分散剂含量1.0%,纳米粒子含量4%的最优参数下纸张平滑度值4.32s;选取保水剂含量、生物胶乳含量、纳米粒子含量对纸张表面强度进行响应面分析,在保水剂含量0.8%,生物胶乳含量18%,纳米粒子含量4%的最优参数下纸张表面强度值1.06m/s。
The choice of paint formulation affects not only the properties of the coated paper, but also the final quality of the coated paper. The impact of different additives on the paint and paper performance are also different. In this paper, single-factor analysis was conducted on the influence of the coating solid content, water-retaining agent, bio-latex, dispersant and other papermaking additives and nano-particles on the rheological properties and paper properties of paper coatings. On this basis, the response surface analysis of the paper smoothness was carried out by selecting the content of solid, dispersant and nano-particle content. Under the optimum parameters of 55% of solid content, 1.0% of dispersant and 4% of nanoparticle content, the paper smoothness Value of 4.32s; selected water retention agent content, bio-latex content, nano-particle content on the surface of the paper response surface analysis, in the water content of 0.8%, the content of bio-latex content of 18%, 4% Intensity 1.06m / s.
