Problems solved by technology

However, due to the large number of speckled bricks, the processing process is complicated, and the speckle particles are easy to divert during the process, which can easily lead to uneven distribution of spots and fluctuations in color, making it difficult to produce stably for a long time. , the color is not easy to fluctuate and can be easily processed and produced.

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with embodiment:

[0026] The preparation method of this stable spot brick, comprises the following steps:

[0027] ⑴Body pressing: the green body powder is composed of conventional powder and spots; the particle size of regular powder is 0.3-0.6 mm, the particle size of speckled powder is 1-3 mm, and the spots are composed of white, blue and black spots. The proportion of white spots is 8%, the proportion of blue spots is 16%, and the proportion of black spots is 76%;

[0028] ⑵ Body drying: drying temperature 80-130 ℃, drying time 40-60 minutes;

[0029] (3) Simulation treatment: Before pattern decoration, a translucent glaze layer is applied on the surface of the body in advance, and the color of the glaze layer is adjusted to be close to the surface color of the body, and then the inkjet printing decoration technology is used to print out the size and size of the spots on the body. Inkj...

Abstract

The present invention relates to a method for preparing stable speckled bricks. The preparation method includes: (1) green body pressing: white spots proportioning 5-10%, blue spots proportioning 10-20%, black spots proportioning 70-80%; (2) green body drying: temperature 80-130°C, time 40 to 60 minutes; ⑶ Simulation processing: apply a translucent glaze layer on the surface of the body, and then use inkjet printing to print inkjet false spots that are close to the size and color of the spots on the body. The color and spot effect of the translucent glaze are consistent with the body. The color and surface effect are basically consistent; ⑷Printing and decoration; ⑸Applying protective glaze: After decorating the color and pattern effects through screen printing, rubber roller printing or inkjet printing, apply transparent glaze slurry to protect the decoration, so that the spots can sink under the glaze layer , achieving highly simulated fusion with the spots on the green body itself; ⑹ Firing: temperature at 1150~1250℃, time 40~60 minutes.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a method for preparing stable spotted bricks. Background technique [0002] Currently popular speckled brick products on the market generally add a variety of different spots to the green body to express the surface spot effect, and then directly print and decorate the green body. However, due to the large number of speckled bricks, the processing process is complicated, and the speckle particles are easy to divert during the process, which can easily lead to uneven distribution of spots and fluctuations in color, making it difficult to produce stably for a long time. , the color is not easy to fluctuate and can be easily processed and produced. Contents of the invention [0003] The purpose of the present invention is to provide a translucent glaze layer applied to the green body before printing and decoration, and inkjet printing and decorative emulation spots are carried o...
