易干擦黑色白板笔墨水性能的优化

摘要

The white board black dry erase ink,which is of smooth writing,pure colour,easy wiping,can be developed. The ink was comprised of solvent (ethanol and isopropanol), colorant(black pigment) , binder (polyvinyl butyral) .separating agent (polyoxyethylene ether) ,humectant (glycerine and trietha-nolamine), release agent (liquid paraffin and laurate) ,plasticizer (butyl stearate). The influences of stirring time, liquid paraffin, proportion of resin/pigment, laurate and triethanolamine on the writability, coloration, stability,erasability were studied. Technology and composition of the ink were optimized. The problem of white oil on the marker tip and white dots in the writing were resolved.%以乙醇、异丙醇为溶剂,黑色颜料为着色剂,聚乙烯醇缩丁醛为成膜剂,聚氧乙烯醚型非离子表面活性剂为分散剂,甘油和三乙醇胺为保湿剂,液体石蜡和月桂酸酯为剥离剂,硬脂酸丁酯为增塑剂,制得了书写流畅、色彩纯正、性能稳定、易于干擦的醇溶性黑色白板笔墨水.研究了搅拌时间、液体石蜡、树脂和颜料的配比、月桂酸酯和三乙醇胺等因素对墨水的流畅性、颜色、稳定性、可擦性的影响,优化了墨水的配方和制备工艺,解决了笔尖析出白色油状物和字迹中的白点等问题.
