Description
Technical Field
The invention relates to ceramic digital protective glaze ink, a preparation method and application thereof.
Background
In recent years, the application of ceramic ink-jet printing technology in China is popularized, and the decorative patterns of ceramic tiles are more abundant due to the development progress of the technology. However, homogeneity of the tiles has also become increasingly severe. At present, the mainstream fully-glazed products on the market have been prevalent for many years, the product homogeneity is serious, the price is fierce, the product quality is also uneven, and the development of the industry is very unfavorable.
In 2020, the most explosive rock plates are in the ceramic industry, and the appearance of the rock plates provides a new opportunity for the ceramic industry when the internal and external environments are increasingly severe. The rock plate can be used for the decoration of background walls, dining table tops, tea tables, counters, wardrobe doors, kitchen stoves, caravan floors and the like due to the unique decoration effect. Rock furniture is also rapidly enjoyed by consumers. With the further maturity of the rock plate processing market in future, the rock plate market can be further expanded, and the development prospect is huge.
The decorative effect of the rock plate is distinctive because the raw materials and production processes of the rock plate are different from those of the conventional ceramic tile. The application of the digital protective glaze cannot be separated in the production of the rock plate. The production of the rock plate needs to be carried out through the processes of green pressing, drying, face glaze spraying, pattern ink-jet printing, protective glaze ink-jet printing, drying and sintering. The glaze ink is protected on the outermost surface of the ceramic tile, so that the color development of the patterns is influenced, and the effects of surface glossiness, antifouling property, hand feeling, wear resistance and the like of the whole ceramic tile are determined.
At present, the mainstream rock plate matched digital protective glaze ink in the market is basically imported due to the fact that the production and application of the rock plate are earlier than those in China. If the digital protective glaze ink can be prepared, the same decorative effect can be achieved and even the effect of the digital protective glaze ink exceeds that of the imported digital protective glaze ink, the development of the domestic rock plate market can be better promoted, and the digital protective glaze ink has great significance for ceramic enterprises and consumers.

The raw material quality of the rock plate test plate overglaze is as follows: 40 parts of potassium feldspar, 8 parts of kaolin, 5 parts of quartz, 16 parts of wollastonite, 10 parts of calcined talc, 13 parts of barium carbonate, 5 parts of zinc oxide and 1 part of alumina. The firing temperature is 1180 ℃.
The results of gloss measurements after firing using the ceramic digital protective glaze inks of examples 1 and 4 printed on the surface of a rock plate in a grid pattern are shown in the following table, where 0 to 50 in the first row are the print gradations of the ink of example 1, 0 to 50 in the first column are the print gradations of the ink of example 4, and the intersections are the gloss measurements.
According to the table, the glossiness of the rock plate prepared by the ceramic digital protective glaze ink in the embodiment of the invention can be changed between 3 and 20 degrees, the glossiness selection range is wide, and the hand feeling is fine. The sample brick is detected by the detection company Limited in the institute of ceramics in Fushan City, the Mohs hardness reaches 6 grades, the wear resistance can reach 4 grades, and the high-concentration acid and alkali resistance experiment can reach GHA grade.
The foregoing is a more detailed description of the invention and is not to be taken in a limiting sense. It will be apparent to those skilled in the art that simple deductions or substitutions without departing from the spirit of the invention are within the scope of the invention.
