Problems solved by technology

However, these ceramic inks and their preparation methods in the prior art generally have some deficiencies, the main defects of which are: 1) The ceramic ink prepared by the above method is corrosive to the nozzle of the ceramic inkjet printer, thus affecting the nozzle 2) It is difficult to control the size of ceramic pigment particles below 1 micron, and it cannot be uniformly dispersed, and its preparation process is relatively complicated, so it is difficult to realize industrial production; 3) Due to the ceramic production process The high firing temperature makes it difficult for ceramic pigments with poor thermal stability to develop color stably. Resulting in a trade-off in color in order to produce high-quality tiles

Abstract

The invention relates to the technical field of ceramic ink jetting, in particular to ceramic ink-jet ink with low viscosity and a preparation method thereof. The ceramic ink-jet ink comprises the following component according to weight percentage: 35-60 percent of ink diluent, 30-55 percent of ceramic colorant, 0.5-4 percent of ink auxiliary agent and 0.5-10 percent of resin. The ceramic ink-jet ink has low viscosity and low surface tension, is applicable to an ink printing spray head with high precision, and can be applied to a Sayre 1001-type spray head and an American north star 512-type spray head; the ink does not contain water, so that the ink does not corrode a spray head of an ink-jet printer in the using process and the service life of the spray head can be obviously prolonged. The preparation method of the ceramic ink-jet ink comprises the following steps of primarily grinding by using a ball mill and performing refined grinding by using a sand mill, so that the production cost is greatly saved, and the preparation method of the ceramic ink-jet ink is efficient.

Description

technical field [0001] The invention relates to the technical field of ceramic inkjet, in particular to a low-viscosity ceramic inkjet ink and a preparation method thereof. Background technique [0002] Ceramic inkjet technology is a technology that applies inkjet printing technology to the surface of ceramics for decoration. It makes ceramic ink from the ceramic powder to be formed, and uses a special printer to print the configured ceramic ink directly on the surface of architectural ceramics. Forming, the shape and geometric dimensions of the formed body are controlled by computer. Ceramic inkjet technology can increase the resolution of products from 72dpi of ordinary technology to 360dpi. If represented by popular pixels, it can be increased from 2.4 million pixels of existing roller printing effect to 12 million pixels, thus making ceramic inkjet Printing technology has gradually replaced traditional technology. Since my country introduced the first ceramic inkjet ma...
