Problems solved by technology

Under different firing processes, the chromaticity of the same glaze will change greatly, which will affect the quality of the obtained enamel. At present, the color difference value of commercially available titanium glazes can reach more than 5 under different firing process conditions. unstable

Embodiment 1

[0024] A kind of enamel titanium color glaze, including the following components: SiO 2 , B 2 o 3 , Al 2 o 3 , CaO, TiO 2 , BaO, Na 2 O, K 2 O, MgO, P 2 o 5 , SO 3 , ZnO, Cr 2 o 3 , CuO, the concrete massfraction of each component is shown in Table 1; The glaze obtained in Example 1 is fired in the following three process conditions respectively:

[0025] 790°C, firing for 4.5min;

[0026] 820°C, firing for 4.5min;

[0027] 840°C, firing for 4.5min;

[0028] The enamel fired under the above process conditions was tested for L, a, b, and G values ​​using a colorimeter of the model CD-6834 / 6836 produced by BYK in Germany. The specific values ​​are shown in Table 2. The chromaticity values ​​obtained under are denoted as L 0 、a 0 , b 0 , the chromaticity values ​​obtained under the firing conditions of 790°C and 840°C are recorded as L i 、a i , b i , through the Hunter color difference formula:

Embodiment 2

[0034] The main difference between this embodiment and Example 1 is that the mass fraction of each component of the glaze is different, and the specific differences are shown in Table 1; the test results of the different firing temperatures of this embodiment are shown in Table 2 and Table 3.

Embodiment 3

[0036] The main difference between this embodiment and Example 1 is that the mass fraction of each component of the glaze is different, and the specific differences are shown in Table 1; the test results of the different firing temperatures of this embodiment are shown in Table 2 and Table 3.

Abstract

The invention discloses an enamel titanium colored glaze. The enamel titanium colored glaze is prepared from, by mass, 30-38% of SiO2, 15-19% of B2O3, 5-8% of Al2O3, 3-5% of CaO, 12-18% of TiO2, 7-10%of BaO, 10-15% of Na2O, 3-5% of K2O, 0.5-0.8% of MgO, 2-4% of P2O5, 0.05-0.1% of SO3, 2-5% of ZnO, 0.1-0.3% of Cr2O3 and 0.3-0.5% of CuO. The enamel titanium colored glaze is stable in color and small in chromatic aberration under different firing temperatures, and the quality of enamel surfaces is good.

Description

technical field [0001] The invention relates to an enamel glaze, in particular to a color-stable titanium color enamel glaze. Background technique [0002] At present, most of the titanium glazes used in the world are white, and there is no color titanium glaze with a relatively stable color at home and abroad. The requirement for the color stability of titanium glaze means that the color change is small under different firing processes. According to the Hunter color difference formula, the color difference value is within 2.5. [0003] With the continuous progress and development of enamel, enamel products are widely used in different fields, such as facade decoration of tunnels and subways; external protection and decoration of curtain walls, etc. With the development of the times, customers have more and more stringent requirements on color difference, and the current board is getting bigger and bigger, and the bigger the board, the more difficult it is to guarantee the ...
