A dry grain decorative ceramic tile with strong three-dimensional effect and its manufacturing method

Abstract

The invention relates to the technical field of ceramic tiles, in particular to a dry granular decorative ceramic tile with strong three-dimensional effect and a manufacturing method thereof. The manufacturing method comprises the following steps: A. Underglaze decoration: performing underglaze decoration on the surface of the green body; B. Pattern decoration: controlling the temperature of the green body at 40-60° C., and then performing pattern decoration on the underglaze surface; C. , drying: drying the green body after pattern decoration; D, dry grain decoration: spreading dry grain on the dried green body surface; E, spraying protective glaze: spraying protective glaze on the green body surface after dry grain decoration; F. Firing: firing the green body after spraying protective glaze. The manufacturing method of the dry granular decorative ceramic brick of the present invention has simple operation steps, convenient control, high production efficiency, low production cost, clear pattern and clear layers of the prepared ceramic brick product, low glaze gloss, good anti-skid effect, dry It has obvious graininess, strong three-dimensional effect, rich colors and stable performance, which can be applied to large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to a dry granular decorative ceramic tile with strong three-dimensional effect 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 n...

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, currently there is a kiln used to suck away the dry particles. The fan inside the kiln rotates to form a negative pressure to suck away the dry particles that are not glued. 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 products, it will cause defects such as dirt, karst caves, and pinholes on the glazed surface of the product, and it will take manpower and material resources to remove the kiln wall. and kiln roof 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
