[0027] In parts by weight, successively get 20 parts of aluminum chloride hexahydrate, 120 parts of water, 20 parts of cobalt chloride hexahydrate, 8 parts of phospholipids, 5 parts of polyols, 5 parts of stabilizers, and 5 parts of esters. Aluminum chloride hexahydrate and water were placed in a three-necked flask, stirred and mixed for 60 minutes at a speed of 500r / min, then added dropwise to the three-necked flask with ammonia water with a mass fraction of 20% to adjust the pH to 7.2, and then added to the three-necked flask Add cobalt chloride hexahydrate, stir and mix for 60 minutes at a speed of 800r / min, then add phospholipids, polyols, stabilizers, and esters into a three-necked flask, and stir and mix for 60 minutes at a speed of 800r / min , that is, special ink for cobalt blue ceramic glaze. The emulsifier is emulsifier OP-10. The phospholipid is milk phospholipid. The polyol is polybutylene adipate diol. The stabilizer is methyl tin mercaptide. The ester substanc...

Abstract

The invention discloses a preparation method of cobalt blue ceramic glaze special-use ink, and belongs to the technical field of ceramic ink jet. The method comprises the following steps: 1) stirring, mixing and dissolving copper nitrate and water to obtain mixed slurry, dropwise adding ammonia water into the mixed slurry, adjusting the pH value of the mixed slurry, adding gellan gum and an emulsifier, stirring and mixing all the components, carrying out heat preservation, standing and aging on the mixture, and carrying out reduced pressure concentration and low-temperature spray drying to obtain a modified additive; and 2) mixing aluminum chloride hexahydrate, water and the modified additive, dropwise adding ammonia water to adjust the pH value, adding cobalt chloride hexahydrate, stirring and mixing all the components, adding phospholipid, polyol, a stabilizer, an ester substance and carbomer, and finally stirring and mixing all the components to obtain the special ink for the cobalt blue ceramic glaze. The special ink for the cobalt blue ceramic glaze provided by the invention has excellent storage stability.

Description

technical field [0001] The invention discloses a preparation method of a special ink for cobalt blue ceramic glaze, which belongs to the technical field of ceramic inkjet. Background technique [0002] With the development of computer technology, digital technology has become more and more widely used in traditional manufacturing, and has become an important technology in the manufacturing industry. Inkjet printing technology is a non-contact digital printing technology successfully developed in the late 1970s. It sprays ink onto the surface of various media through the nozzles on the print head, realizing non-contact, high-speed, low-noise monochrome and color text and image printing. [0003] One of the key technologies of ceramic inkjet printing is the preparation of ceramic ink. The so-called ceramic ink is a suspension or emulsion containing a certain special ceramic powder, usually including ceramic powder, solvent, dispersant, binder, surfactant and other auxiliary ...
