Printing processing technology for surface of ceramic tile

Abstract

The invention discloses a printing processing technology for the surface of a ceramic tile, which comprises the following steps of (1) surface cleaning: processing the glaze surface of the tile or or the body surface of the tile into a matte surface by utilizing an abrasive blasting or abrasive frosting method; (2) pattern printing: printing patterns on the matte surface of the tile obtained in the step (1) by utilizing an ultraviolet light curing printing machine with UV (Ultraviolet) ink; and (3) protection processing: enabling transparent UV paint to be attached to the surface of the semi-finished product obtained in the step (2) by adopting a spraying or printing or curtaining or roller painting method, and then spreading the UV paint uniformly on the tile surface printed with the patterns by using an ultraviolet light leveling production line; and finally curing and drying the tile surface by using an ultraviolet light curing machine to finish the entire technological process. The printing processing technology has the advantages that the technological steps are simple; the printing production cycle of a tile product can be shortened to 30 minutes; the production efficiency is greatly enhanced; the production step of sintering at high temperature is avoided; the energy consumption can be obviously reduced, and the pollution is lightened; and the patterns printed by utilizing the UV ink have the advantages of high color saturation, vivid and bright color, and high product quality.

Description

technical field [0001] The invention relates to a tile surface treatment technology, in particular to a tile surface printing treatment process. technical background [0002] Ceramic production is an industry with high energy consumption, high pollution, and high cost. The existing ceramic tile surface printing process generally includes three methods: screen printing, roller printing, and inkjet printing. The process of the first two methods is very complicated and needs to be designed. The figure shows that film-drawing-photosensitive plate-making-printing-high-temperature firing and many other links can be completed. The production cycle of a product takes 3-5 days, and the high-temperature firing temperature reaches 850°C-1250°C, which not only consumes more energy. High, it will also produce exhaust gas pollution, and, due to the limitation of the number of screen plates and the characteristics of the glaze itself, the color saturation of the printed pattern is not high...

The figure shows that film-drawing-photosensitive plate-making-printing-high-temperature firing and many other links can be completed. The production cycle of a product takes 3-5 days, and the high-temperature firing temperature reaches 850°C-1250°C, which not only consumes more energy. High, it will also produce exhaust gas pollution, and, due to the limitation of the number of screen plates and the characteristics of the glaze itself, the color saturation of the printed pattern is not high, the color is easy to be distorted, and the product often cannot meet the requirements of the design draft; inkjet Although the printing method is relatively simple, it also needs to be fired at high temperature, and there are also problems of high energy consumption and exhaust gas pollution, which need to be improved
