A kind of inkjet dry granular decorative ceramic tile and its manufacturing method

Abstract

The invention relates to the technical field of ceramic tiles, in particular to an inkjet dry particle decorative ceramic tile and a manufacturing method thereof. The manufacturing method comprises the following steps: A, bottom glaze decoration; B, pattern decoration; C, first drying; D, dry particle decoration; E, spraying protective glaze; F, firing. The method for preparing dry grain decorative ceramic tiles of the present invention has simple operation steps, convenient control, simplified process flow, improved production efficiency, reduced production difficulty and production cost, and is applicable to industrialized large-scale production; by using dry grain ink for spraying, it can Spray printing at the designated position on the surface of the green body, so that the texture of the spray printing can accurately correspond to the texture of the pattern decoration, improve the distribution uniformity and adhesion of the dry particles on the surface of the green body, and make the pattern of the prepared ceramic tile product clear, Clear layers, low glaze gloss, good anti-slip effect, obvious dry grain feeling, strong three-dimensional effect, rich colors, stable physical and chemical properties, and wide temperature range.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to an inkjet dry particle decorative ceramic tile and a manufacturing method thereof. Background technique [0002] With the improvement of people's living standards, in the selection of decoration and decoration materials, the requirements for the quality and appearance of ceramic tiles have been significantly improved; at the same time, with the development of society and the advancement of science and technology, the application of ceramic inkjet technology in the field of ceramics Increasing, making the surface effect of ceramic tiles on the market more and more abundant. [0003] The current ceramic inkjet technology is to apply dry particles by combining glue and dry particles after inkjet, apply glue to the part where dry particles need to be applied, and then apply dry particles on the surface of the tiles, and The dry particles that are not glued to the glue are remo...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many defects in the current inkjet, sizing and dry granulation processes, which make the three-dimensional effect of the surface of ceramic tiles not obvious, and the production efficiency is low:

[0006] (2) Inkjet pattern, sizing and dry granule cloth are integrated. When the dry granule cloth is unloaded, a large amount of dust will be generated, which will affect the normal operation of the nozzle of the inkjet equipment, and even block or damage the nozzle, reducing the service life of the production equipment. ;

[0007] (3) When sucking away the dry particles that are not glued by glue, at present, the kiln is used to suck away the dry particles, and the negative pressure is formed by the rotation of the fan inside the kiln, and the dry particles that are not glued by glue are sucked away. However, these dry particles are easy to stick to the kiln wall and kiln roof. When the kiln is suitable for the production of other types of layered products, it will cause defects such as burials, caves, and pinholes on the right glaze of the product, and it will take manpower and material resources to remove them. Kiln walls and roofs and dry pellets;

[0008] (4) When the body glued with dry grains is fired in the kiln, the glue has not yet volatilized and solidified completely, the glaze and the dry grains have not yet begun to melt and produce a melt, and the dry grains on the ground surface are absorbed by the kiln. The fan blows or sucks away, which greatly reduces the amount of dry particles on the glazed surface of the product, and even makes there are no dry particles on the glazed surface, so that the three-dimensional effect of the surface of the finished ceramic tile is not obvious. At the same time, the kiln will also produce dirt, which reduces the Improve the quality of finished ceramic tiles
