水性纳米色浆、含其的水性热升华喷墨墨水及其制备方法
摘要：
本发明公开了一种水性纳米色浆、含其的水性热升华喷墨墨水及其制备方法。所述的水性纳米色浆，其原料配方包括下述以重量份计的组分：热升华染料10～40份，包覆处理剂1～20份，分散剂1～80份，助剂1～30份，和水10～400份。所述的水性纳米色浆中热升华染料以染料颗粒的形式存在，其平均粒径小于100纳米。本发明采用独特的两步分散工艺，先对热升华染料进行表面包覆处理，再进行纳米分散，得到了稳定的水性纳米色浆。将所得的水性纳米色浆与树脂、助剂、助溶剂和水混合均匀即可得到水性热升华喷墨墨水。
摘要（英）：

The invention discloses water-based nanometer color paste, water-based thermal sublimation jet ink containing the same, and a method for preparing the water-based thermal sublimation jet ink. The water-based nanometer color paste is prepared from, by weight, 10-40 parts of thermal sublimation dye, 1-20 parts of cladding treating agent, 1-80 parts of dispersing agent, 1-30 parts of auxiliaries and 1-400 parts of water. The thermal sublimation dye in the water-based nanometer color paste exists in the form of dye particles, and the mean grain size of the dye particles is smaller than 100 nanometers. A unique two-step dispersion technology is adopted, the thermal sublimation dye is subjected to surface cladding and nano-scale dispersion in sequence, and then the stable water-based nanometer color paste is obtained. The obtained water-based nanometer color paste is evenly mixed with resin, auxiliaries, cosolvent and water to obtain the water-based thermal sublimation jet ink.
