| 摘要:水彩纸作为水彩画专门用纸，其浸润性对水彩画面的效果有着重要影响。本研究将水彩纸在105℃恒温箱中进行72 h老化处理，分析老化前后水彩纸与质量分数为0（蒸馏水）、0.02%、0.04%、0.06%水彩颜料溶液在纸张表面的静态接触角变化趋势，并使用傅里叶变换红外光谱仪、X射线衍射仪、扫描电子显微镜对老化前后水彩纸表面进行微观形貌分析。结果表明，与0、0.02%、0.04%、0.06%水彩颜料溶液的平均瞬时接触角测试老化前水彩纸分别为117.607°、120.086°、122.864°、122.275°；老化后水彩纸分别为115.737°、119.045°、114.279°、115.147°。老化实验前后水彩纸浸润性未发生明显变化，均具有疏水性。老化后水彩纸与0.04%和0.06%水彩颜料溶液的接触角变化较大，相比老化前，平均瞬时接触角分别下降8.585°、7.128°。分析发现，老化对水彩纸的浸润性影响不大。 |
| Abstract:As a special paper for watercolor painting, watercolor paper has an important influence on the effect of watercolor painting. In this study, the watercolor paper was aged for 72 h in a incubator at 105℃, and the static contact angles of the watercolor pigment solution with pigment mass fraction of 0.02%, 0.04%, and 0.06% on the surface of the watercolor paper before and after aging were measured. Fourier transform infrared spectrometer, X-ray diffractometer, and scanning electron microscope were used to analyze the micro-morphology of the paper surface before and after aging. The results showed that the average contact angles of the watercolor paper before aging with 0 （distilled water）, 0.02%, 0.04%, and 0.06% watercolor pigment solutions were 117.607°, 120.086°, 122.864°, and 122.275°, respectively; the corresponding aged watercolor paper average contact angles were 115.737°, 119.045°, 114.279°, and 115.147° respectively. The wettability of the watercolor paper did not change significantly before and after the aging experiment, and it was hydrophobic. After aging, the contact angle of the watercolor paper with 0.04% and 0.06% watercolor pigment solutions changed greatly. |
