纳米埃洛石对涂料及涂布纸性能的影响

Effect of Nano-sized Halloysite on Properties of Coating and Coated Paper

以纳米埃洛石、GCC、Clay组成颜料体系,研究纳米埃洛石用量对涂料及涂布纸性能的影响。研究结构表明,纳米埃洛石独特颗粒形态及尺寸,使其对涂料及涂布纸的性能有较大的影响。涂料的粘度随埃洛石用量的增加而增大,涂料保水值略有减小;使用埃洛石后,涂布纸白度、光泽度、表面印刷强度随着其用量的增加而增大,纸张的平滑度、油墨吸收性也有一定的改善。

The effect of the amount of nano-sized halloysite on the properties of coating and coated pa- per was studied, with halloysite, GCC, Clay as pigments. The results showed that, the nano-sized halloysite has special particle morphology and size, and it has significant influence on coating and coa- ted paper. The viscosity of coating increased with the increase of the amount of halloysite , and the water retention value becomes a little smaller. The brightness, gloss, surface printing strength in- creased with the increase of the amount of halloysite , and the smooth, ink absorption also have certain improvement.
