Abstract

The invention discloses a preparation method of a high-temperature yellow pigment for ceramic laser printing.The preparation method comprises a preparation method for synthesizing a praseodymium ion-doped zirconium silicate yellow pigment by adopting a semi-liquid phase semi-solid phase technology and a method for preparing laser printing ink powder through an emulsion polymerization technology.The preparation method comprises the steps that a zirconium salt solution and an alkaline solution are simultaneously and dropwise added into water to form colloid of zirconium, white carbon black is added, the mixture is stirred to form zirconium-silicon mixed colloid, and filter pressing, washing and drying are performed to obtain superfine zirconium-silicon mixed powder; the zirconium-silicon mixed powder, praseodymium oxide, fluoride salt and chlorizated salt are mixed to be uniform according to a certain mass ratio and then calcined, and the praseodymium ion-doped zirconium silicate yellow pigment is obtained; the synthesized pigment, resin and a charge control agent are mixed to be uniform and then subjected to high-temperature mixing, extruding, cooling, breaking, air flow smashing, cyclone classifying and surface modifying, and the yellow ink powder for ceramic laser printing is obtained.According to the preparation method, by self-making an inorganic pigment and resin, the inorganic pigment and a polymerization coating technology adapt to each other to the maximum limit.

Description

technical field [0001] The invention relates to a high-temperature-resistant yellow pigment, in particular to a preparation method of a high-temperature yellow pigment for ceramic laser printing. Background technique [0002] The decoration methods of ceramic materials mainly include decals, roller rubber printing and inkjet printing. These three decoration techniques can basically meet the large-scale decoration needs of various ceramic products. With the improvement of decoration and the expansion of personalized market demand, the existing decoration methods are gradually insufficient. A recently launched ceramic laser printing process not only has better and more delicate and realistic decorative effects, but also can design decorative patterns for customers, and some can even achieve 3D appearance quality, so it is more and more favored by enterprises and customers. [0003] Before being applied to ceramic decoration, laser printing technology is a technology widely us...
