摘要
为了研究白色水性柔印墨的遮盖力,对油墨成分进行了研究,改变颜料的种类、研磨树脂的种类、颜基比以及分散剂的种类和含量、成膜树脂种类,配制油墨,测试油墨分散性,并将油墨涂布到遮盖力测试纸上,测试墨膜的遮盖力。结果表明:分散性是影响油墨遮盖力的主要因素;颜料和树脂种类以及两者之间的比例是影响油墨遮盖力的关键因素;分散剂种类、含量以及分散时间也对油墨遮盖力有一定影响。
In order to research the covering property （ CP ） of white water-based flexo ink, this paper studies the component part of ink, which is prepared by changing （ a） the variety of both pigments and resins, （ b） the ratio of pigment to resin, （ c） the variety and the content of dispersants and （ d ） the variety of film-forming resins. This paper tests the diameter size, coating it onto the surface of the covering power test paper to get their CP data. It has been testified that the dispersion property is the major factor which influences the CP of white water-based covering ink. The variety of both pigments and resins, the ratio of pigment to resin are the key factors for the CP; the result also proves that different kind of dispersants and contents are also important factors which influence the dispersion property.
