【摘要】 采用均匀设计试验法,得到作为齐聚物使用的光固化水性聚氨酯和聚乙烯醇混合乳液,降低墨水黏度,提高固含量。利用单因素法研究了光引发剂种类、含量以及染料、丙三醇的用量等因素对墨水性能的影响,确定各因素最优用量区间。最后采用正交试验法,确定齐聚物、光引发剂、染料及助剂用量的最优用量,结果表明,当齐聚物75%,染料10%,光引发剂5.5%,助剂1.9%(其中丙三醇1.5%,消泡剂0.4%),稀释剂为去离子水和乙醇7.6%,配制所得的水性UV喷墨墨水综合性能优异。更多还原

【Abstract】 Based on the uniform design method,an aqueous emulsion of waterborne polyurethane and polyvinyl alcohol as an oligomer to decrease ink viscosity is obtained and solid content is improved.The research is conducted on different kinds of photo-initiator,the amount of the photoinitiator,dyes and glycerol about its properties by using the single factor method to determine the optimal amount interval of various factors,with the optimal amount of oligomer,photoinitiator,species and additives being determined finally.The results show that when the formulation is75% oligomer,10% dyes,5.5% photoinitiator,1.9% additives(1.5% glycerol and defoamer0.4%)and 7.6% diluent made of deionized water and ethanol,the comprehensive properties of the water-borne UV-curable printing ink are of excellence.更多还原
