油墨专用纳米碳酸钙的研制
|
摘要
讨论了制备应用于油墨时具有良好透明性、流动性和分散性的纳米碳酸钙生产最佳工艺为:用改性松香树脂作油墨处理剂时可以降低吸油值,提高白度;当碳酸钙的比表面积大于40 m~2/g时,透明性好;用带搅拌的鼓泡碳化法,碳化出来的纳米碳酸钙的分散性好,透明性好,成本较低;加入分散剂可以调节碳酸钙流动度和分散性;通过二次碳化和加入酸可以控制p H的大小。
The optimum process for preparing nano-calcium carbonate with good transparency, fluidity and dispersibility for printing ink is discussed : using modified rosin resin as ink treatment agent can reduce oil absorption value and improve whiteness; when the specific surface area of calcium carbonate is more than 40 m~2/g, the transparency is good; by bubbling carbonization with stirring, the nano-calcium carbonate particles are Good dispersible, transparency and lower cost. Adding dispersant can adjust the fluidity and dispersion of calcium carbonate, The p H value can be controlled by secondary carbonization and adding acid.
