Embodiment 1

[0026] Mix 1.5g of vanadium-zirconium blue material with a particle size of 400 mesh and 20g of transparent frit powder with a particle size of 400 mesh and a glaze forming temperature of 1110°C, then add 9g of water, and ball mill evenly to prepare a colored glaze slurry, and spray the colored glaze with a spray gun. The slurry is evenly coated on the white ceramic glaze fired at 1250°C, so that the thickness of the glaze slurry is 0.15mm. Glaze slurry for drying ceramic glazes.

[0027] Using a fiber laser, adjust the power of the laser to 60W, the defocus to 0.2cm, the scanning speed to 100mm / s, the frequency to 40Hz, and the scanning line spacing to 0.01mm. At this time, the laser temperature can reach 1100-1130°C. Enter the letter "D" on the PC, start to heat the dried color glaze slurry with laser scanning, wash off the remaining dry color glaze slurry, and leave a clear, bright blue, smooth "D" pattern on the glaze surface ,Such as figure 1 shown

Embodiment 2

[0029] Mix 1.5g of cobalt-magnesium-tin color material with a particle size of 400 mesh and 20g of transparent frit powder with a particle size of 400 mesh and a glaze forming temperature of 1110°C, then add 9g of water, and ball mill evenly to prepare a colored glaze slurry, and use a spray gun to The color glaze paste is evenly coated on the white ceramic glaze fired at 1250°C, so that the thickness of the glaze paste is 0.15mm. Glaze slurry for drying ceramic glazes.

[0030] Using a fiber laser, adjust the power of the laser to 80W, the defocus to 0.2cm, the scanning speed to 100mm / s, the frequency to 40Hz, and the scanning line spacing to 0.01mm. At this time, the laser temperature can reach 1100-1130°C. Enter the letter "D" on the PC, start to heat the dried color glaze slurry with laser scanning, wash off the remaining dry color glaze slurry, and leave a clear, bright blue, smooth "D" pattern on the glaze surface ,Such as figure 2 shown.

Embodiment 3

[0032] Mix 1.5g of cobalt-magnesium-tin color material with a particle size of 400 mesh and 20g of transparent frit powder with a particle size of 400 mesh and a glaze forming temperature of 1110°C, then add 9g of water, and ball mill evenly to prepare a colored glaze slurry, and use a spray gun to The color glaze paste is evenly coated on the white ceramic glaze fired at 1250°C, so that the thickness of the glaze paste is 0.01mm. Glaze slurry for drying ceramic glazes.

[0033] Using a fiber laser, the power of the laser is adjusted to 80W, the defocus is 0.2cm, the scanning speed is 100mm / s, the frequency is 40Hz, and the scanning line spacing is 0.01mm. At this time, the laser temperature reaches 1240-1260°C. Enter the letter "D" on the PC and start scanning with laser. After washing with water, it turns out that because the color glaze paste is too thin and the laser energy is high, not only the painted color glaze paste is not printed, but also the glaze surface to be dec...

Abstract

The invention provides a ceramic glaze decoration method. The method adopting a laser decoration mode mainly comprises the following steps: 1, uniformly mixing a pigment with a glaze to prepare a color glaze slip; 2, directly or indirectly adhering the color glaze slip to a glaze to be decorated; 3, drying the color glaze slip; 4, adjusting laser parameters, and scanning the adhered dry color glaze slip by using high energy laser; and 5, flushing by using clear water. A bright-color customized character or pattern is left in the laser scanning position. The method can be used for marking the surface of a finished product white ceramic glaze and drafting the customized color pattern; and compared with traditional kiln roasting, the method provided by the invention has the advantages of energy saving and environmental protection due to small laser power.

Description

technical field [0001] The invention belongs to the technical field of ceramic color decoration and the field of laser application, in particular to a ceramic glaze color decoration technology. Background technique [0002] At present, the existing ceramic glaze decoration technology mainly includes decals, printing, spray flowers, ancient colors, ink colors, etc., among which decals are the most widely used. These technologies must transfer the ceramics to the kiln and burn them at a high temperature of 700-1100 ° C. Not only the operation is cumbersome, the efficiency is low, but also the energy consumption is huge. Bending or cracks appear, and the scrap rate is greatly increased. [0003] On the other hand, lasers are more and more widely used in the processing and manufacturing industry, especially in the processing of metal materials. In recent years, lasers have also been gradually applied to ceramic processing. [0004] In the prior art, one is to use laser to abla...
