Shrink-proof glazing agent and its application

Abstract

The invention discloses an anti-shrinkage glaze and its application. The anti-shrinkage glaze is calculated by mass percentage and consists of the following components: 50-80% of a water-based substrate wetting agent, 3% of a polyether-type nonionic surfactant ~5%, the balance is solvent. The anti-shrinkage glaze is used in inkjet printing of ceramics. The anti-shrinkage glaze agent of the present invention can effectively reduce the dynamic surface tension of the glaze slurry for ceramic inkjet printing, without foaming and stable foaming, and can also greatly improve the flow and spreadability of the glaze slurry and the wetting of the substrate and pigments It can effectively solve the phenomenon of glaze shrinkage and improve the excellent rate of finished products. In addition, the formula can be produced under normal temperature and pressure, and the process is simple, which is convenient for widespread popularization and use.

Description

technical field

[0001] The invention belongs to the building pottery industry, and in particular relates to an anti-shrinkage glaze and its application. Background technique

[0002] 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. On the basis of inkjet printing technology, the ceramic pigment powder is prepared into ink, and through computer control, the configured ink can be directly printed on the surface of architectural ceramics for decoration by using a special printer. China entered the field of ceramic inkjet printing later than Italy and Spain. It has also begun to rise rapidly in the past two years and has shown a good momentum of development. As of the first half of this year, China has more than 200 ceramic inkjet printers...
