Study On Vanadium Zirconium Yellow And Cobalt Silicate Blue Non-granule Ceramic Ink

With the development of ink-jet printing technology,the use of ink-jet printing decorative ceramic surface has gradually attracted people's attention.Compared with traditional ceramic surface decoration technology,ink-jet printing technology exists obvious advantages,such as energy saving,clear image and high degree of automation.Currently,the domestic-use ceramic ink is prepared by dispersing submicronic and nanometric pigment particles with dispersant.However,the existence of insoluble particles may bring nozzle clogging,which increase the probability of damage to the printer head.In addition,generating precipitation prematurely during transport due to powder agglomeration seriously affect the stability of ceramic ink.The aim of this study is to create a stable and homogeneous ceramic ink without insoluble particles by the reaction between inorganic salts and organic acids,forming water-soluble metal complex compound.The results of this paper are of great theoretical and practical significance for the development and application of ink-jet printing.Specific research contents and results are as follows:(1)The first part of the paper shows the chemical synthesis of Zirconium gallic and Vanadyl acetylacetonate,after which the ceramic ink was prepared by dissolving Zirconium gallic and Vanadyl acetylacetonate into ammonia liquid.The result indicates that:the ink shows the optimum physicochemical properties when the molar ratio of Zirconium gallic and Vanadyl acetylacetonate is 14:1 and the content of organic compounds in ammonia reaches 35%;After the ceramic ink is calcined at 600? for 120 min,its pigment particle size is about 0.1 ?m,and its yellow performance is relatively stable;Vanadium-zirconium ceramic ink coloring of the main crystal lattice is ZrO2,coloring ions is V5+,belongs to the adsorption color;Vanadium zirconium yellow ceramic ink decorative glazed ceramic that's glazed flat and no defects.Ceramic ink have a good decorative performance,and b value of up to 35.45.(2)The second part of the study prepared by chemical synthesis of cobalt isooctanoate metal,benzyl alcohol as organic solvent preparation of cobalt-silicon blue non-granule ceramic ink.The result shows that:Cobalt isooctanoate and tetraethyl silicate are dissolved in benzyl alcohol at a molar ratio of 1:3.When the organic content reaches 50%,the ink has the best physicochemical properties;After the ceramic ink is calcined at 1150? for 180 min,its pigment particle size is about 2?m,and its blue performance is the best;Zn2+can promote the conversion of Co2+from hexa to tetracoordinate,and make the cobalt-silicon pigment turn from fuchsine to blue.The main crystal lattice of cobalt-silicon blue ceramic ink is Co2SiO4,and the colored ions are Co2+,which belongs to solid-solution color;cobalt-silicon blue ceramic ink decorative glazed ceramic that's glazed flat and no defects.Ceramic ink has a good decorative performance,and b value of up to-45.33.(3)The third part of the paper prepared in the same way tin-vanadium yellow ceramic non-granule ink.The result shows that:Dibutyltin laurate and vanadyl acetylacetonate are dissolved in benzyl alcohol at a molar ratio of 13:1.When the organic content reaches 30%,the ink has the best physicochemical properties.After the ceramic ink is calcined at 1250? for 180 min,its pigment particle size is about 1?m,and its yellow performance is the best;Tin-vanadium ceramic ink is the main grid lattice coloring SnO2,which coloring ions is V5+.It belongs to the adsorption color;Tin-vanadium yellow ceramic ink decorative glazed ceramic that's glazed flat and no defects.Ceramic ink have a good decorative performance,and b value of up to 45.23.
