UV (ultraviolet) photo-cured ceramic inkjet ink and method for using same on ceramic surface for printing

Abstract

The invention relates to the technical field of ceramic inkjet, in particular to UV (ultraviolet) photo-cured ceramic inkjet ink and a method for using the UV photo-cured ceramic inkjet ink on ceramic surface for printing. The method comprises the following steps of: 1) preparing the UV photo-cured ceramic inkjet ink according to formula proportions; 2) putting a moulded ceramic blank into a furnace and baking the moulded ceramic blank for the first time so as to obtain a vitrified ceramic blank; 3) spraying the UV photo-cured ceramic inkjet ink on the surface of the vitrified ceramic blank by a ceramic ink jet machine, and performing UV photo-curing shaping at the same time; and 4) feeding the ceramic blank subjected to the UV photo-curing shaping into the furnace, and baking the ceramicblank for the second time so as to obtain a ceramic finished product. The ceramic inkjet ink provided by the invention is applied to ceramic production, ceramic ink spraying and the UV photo-curing shaping are simultaneously performed on the surface of the ceramic blank which is baked two times, the defect that the ordinary ceramic inkjet ink cannot be sprayed on a baked vitrified tile is overcome, and the UV photo-cured ceramic inkjet ink has a better color development performance compared with the ordinary ceramic inkjet ink, and better keeps high resolution and high accuracy of ceramic inkjet.

Description

technical field [0001] The invention relates to the technical field of ceramic inkjet, in particular to a UV photocurable ceramic inkjet ink and a method for printing on ceramic surfaces. 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 to achieve non-contact, high-speed, Monochrome or color text and graphics printing with low noise. At present, this technology has been widely used in textiles, digital photo printing, office supplies, packaging printing, ceramic printing and other fields. [0003] In recent years, ceramic printing technology has applied inkjet printing technology to ceramics for decoration. It is to make ceramic ink from the ceramic powder to be formed, and use a special printer to directly print the configured ceramic ink to the surface of architectural ceramics. The shape and...

Problems solved by technology

However, the defects of the ceramic ink and ceramic inkjet process in the prior art are: 1) the ceramic ink is easy to diffuse, and at the same time, the diffusion of nano-scale ceramic particles to the embryo body causes the color development performance of the ceramic colorant to deteriorate; 2) the ceramic ink cannot Inkjet on fired vitrified tiles, since the surface of fired vitrified tiles has no capillary pores, the solvent is difficult to absorb, resulting in low-viscosity ceramic inks easily diffusing and blurring, making it difficult to retain the high resolution of inkjet 3) Due to the high firing temperature of the ceramic production process, it is difficult to stabilize the color of ceramic pigments with poor thermal stability, such as red ceramic pigments in ceramic inks at 1200 ° C It is difficult to develop color at high temperature (greater than 1175°C), which will inevitably result in a trade-off in color in order to produce high-quality tiles; 4) It is difficult to control the size of ceramic pigment particles below 1 micron, and they cannot be uniformly dispersed
