| 摘要: |
| 采用半连续乳化法制备了双丙酮丙烯酰胺-己二酸二酰肼改性的丙烯酸酯乳液,配以蓝色碱性颜料配制成水性油墨,讨论了交联体系改性对水性油墨各性能的影响。结果表明,随着DAAM-ADH 的质量分数由0 增加到3%,丙烯酸酯乳液固含量增加,粒径变小,水性油墨的黏度增大,稳定性得到了改善,附着牢度增大,耐水性耐酸碱性增强;当DAAM-ADH 的质量分数继续增加至5%时,水性油墨的黏度显著增大,导致物理凝胶。 |

| Abstract: |
| Water-based ink was prepared by mixing diacetone acrylamide-adipate hydrazide modified acrylate emulsion, which was synthesized by semi-continuous emulsion polymerization with blue alkaline pigment. The effect of crosslinking system modification on performances of the water-based ink was studied. The results showed that when the content of DAAM-ADH increase to 3% from 0%, the solid content of acrylate emulsion increases, the particle size decreases, the viscosity of water-based ink increases, the stability improved, the adhesion increases, the water resistance and acid-alkali resistance became stronger. When the content of DAAM-ADH is up to 5%, the viscosity of water-based ink increase significantly, this results in physical gel. |
