摘　　要：目的研究水性塑料凹印油墨中各种助剂的不同添加量对油墨干燥速度的影响。方法保持水性凹印油墨中颜基比不变,只改变1种助剂的含量比例,采用高速研磨的方法制备塑料水性凹印油墨样品,并通过测试各油墨样品的初干性和黏度,探讨不同质量分数的各助剂对油墨干燥速度的影响。结果适量的助剂用量对油墨的干燥速度有一定的提高,过多的添加则会降低油墨干燥速度。结论 p H稳定剂、增稠剂、分散剂和润湿剂的质量分数分别为0.2%,0.6%,3.0%和2.0%时,不但能相应地提高干燥速度,而且不会对油墨的其他性质如黏度、附着牢度等产生不良影响。Objective To study the influence of different addition amount of auxiliary on the dryness of water-based plastic gravure ink. Methods Sample ink of plastic aqueous ink was prepared by means of high-speed grinding dispersal.All the sample ink pigment/binder ratios were the same and only an additive changed its content. The different contents of auxiliary were analyzed by the way of measuring rough dryness of sample ink. Results Suitable dosage increased the drying rate of ink, while unsuitable dosage decreased the drying rate. Conclusion When the contents of p H stabilizer,thickener, dispersant and wetting agent were respective 0.2%, 0.6%, 3.0% and 2.0%, the drying rate of the water-based plastic gravure ink increased, and meanwhile its qualities including viscosity and adhesion were not negatively affected.
