【摘要】 研究了分别添加中性表面活性剂和阴离子表面活性剂改性后水性油墨的干燥速度,同时表征改性后水性油墨的固含量、黏度、pH值、色差和色密度等性能的变化。研究表明:添加中性表面活性剂与阴离子表面活性剂,均能有效提高水性油墨的干燥速度。其中,中性表面活性剂含量为0.50%时,初干时间为10.96s,水性油墨的干燥速度有明显提高,相比原墨提高了8.89%;阴离子表面活性剂含量为0.83%时,初干时间是10.25s,比原墨干燥速度提高了14.50%。同时,对比水性油墨其他性能,研究发现当中性表面活性剂含量为0.50%、阴离子表面活性剂含量为0.83%时,其水墨各项性能与原墨差异不大。更多还原

【Abstract】 The drying properties of water-based ink modified by neutral surfactants and anionic surfactants respectively were studied. The results show that drying properties of the inks after neutral and anionic surfactant modification are improved, especially at certain adding content. When the neutral surfactants content is 0.50%, the ink initial drying time is 10.96s, increased by 8.89% compared to that of ink unmodif ied; with the addition of some anionic surfactants, the drying time of ink is visibly accelerated, raised by 14.80%; while other properties of the modified inks, including the solid content, viscosity, pH, color density and aberration, have no obvious changes in comparison with those of the original ink.更多还原
