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40m2/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pH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 m2/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 pH value can be controlled by secondary carbonization and adding acid.
