Problems solved by technology

However, the problem with the inkjet process is that in order to ensure the accuracy of inkjet, the color and auxiliary material particles usually need to be very small in size, and the smaller particle size is very easy to change color due to oxidation during the firing process, resulting in bright colors. The degree, that is, the color saturation cannot be guaranteed, and the color is obscure, which affects the appearance effect
However, the porcelain in this scheme is not flexible enough, and there is still room for improvement in appearance

Embodiment 1

[0037] A preparation method of three-dimensional surface glaze comprises the following steps:

[0038] 1. Select at least one single color in the image to prepare a screen version;

[0039] 2. On the semi-finished blank, the upper glaze is printed in a pattern by screen printing, and the upper glaze is powder;

[0040] 3. Fire in a kiln to obtain ceramics with a three-dimensional surface glaze.

[0041] After printing, the stack height of the top glaze is 0.4~5mm at the highest point, and the gap in the pattern is reserved.

[0042] Semi-finished blanks are sintered and dried.

[0043] The surface of the blank is colored in the form of a silk screen.

[0044] A base glaze is applied on the surface of the billet.

[0045] In the third step, an 80-mesh screen is used in the screen printing of the top glaze.

Embodiment 2

[0047] A method for preparing a three-dimensional surface glaze, comprising the following steps:

[0048] 1. Select at least one single color in the image to prepare a screen version;

[0049] 2. On the semi-finished blank, the upper glaze is printed in a pattern by screen printing, and the upper glaze is powder;

[0050] 3. Fire in a kiln to obtain ceramics with a three-dimensional surface glaze.

[0051]After printing, the stack height of the top glaze is 0.5~3mm at the highest point, and the gap in the pattern is reserved.

[0052] Semi-finished blanks are sintered and dried.

[0053] Roll and / or gravure coloring on the surface of the blank.

[0054] A base glaze is applied on the surface of the billet.

[0055] In the third step, an 80-mesh screen is used in the screen printing of the top glaze.

Embodiment 3

[0057] A method for preparing a three-dimensional surface glaze, comprising the following steps:

[0058] 1. Image processing;

[0059] Select at least one single-color color development in the image to prepare a screen screen; the color development refers to visually prominent color blocks, large-area color blocks and color blocks that require bright colors.

[0060] The visually prominent color blocks can be screen-printed to ensure vivid colors with accurate hue, high color saturation and high gloss. The method of screen printing can also have the effect of three-dimensional relief.

[0061] The color blocks of bright colors are required. In the gold formed by inkjet printing, the finished product is displayed as brown, and the effect is not good. Using screen printing, especially the use of metal-containing powder to print gold, has a very Bright effect, high reflectivity, saturated color, and can have the effect of three-dimensional relief, the artistic effect is perfec...

Abstract

The invention provides a preparation method for three-dimensional cover glaze. The preparation method comprises the following steps: I, selecting at least one monochrome from an image to prepare a silk screen plate; II, applying cover glaze on a semi-finished blank in a silk screen printing pattern, wherein the cover glaze is powder; III, baking in a kiln to obtain ceramic with the three-dimensional cover glaze. In the preparation method for the three-dimensional cover glaze, an image pre-treating scheme is adopted, and the advantage of bright color of silk screen printing is utilized, so that a ceramic product with a bright image is obtained.

Description

technical field [0001] The invention relates to the field of ceramic production, in particular to a method for preparing a three-dimensional surface glaze. Background technique [0002] The patterns on the surface of traditional ceramics are mostly drawn by hand, and the colors are bright and beautiful, which are loved by consumers. However, traditional ceramics have high requirements on the painters. When the pattern is complicated, the production efficiency is low, the scrap rate is high, and the labor intensity is high. [0003] After technological development, a ceramic screen printing process has emerged, such as the Chinese patent document CN104924789A, which records a ceramic screen printing process for environmental protection, using a special printing colorant, covering the screen on the white embryo, and using a squeegee Uniform extrusion and smearing make the color material permeate through the pattern on the screen, remove the screen, the color material solidifi...
