Problems solved by technology

However, due to its special structure and composition, the thermal stability of pearlescent pigments is not ideal. When the heat treatment temperature exceeds 700 ° C, pearlescent pigments basically lose their metallic luster.
Therefore, its application range in the ceramic field is very limited

Embodiment 1

[0026] Prepare the ceramic glaze in proportion at room temperature, and control its fineness to 325 mesh; then prepare golden yellow pearlescent pigment according to the requirements, and control its fineness to 600 mesh; in the ceramic glaze at a ratio of 7:3 Add golden yellow pearlescent pigment and stir slowly at room temperature.

Embodiment 2

[0028] Prepare the ceramic glaze in proportion at room temperature, and control its fineness to 325 mesh; then prepare the golden yellow pearlescent pigment according to the requirements, and control its fineness to 600 mesh; Add golden yellow pearlescent pigment and stir slowly at room temperature.

[0029] When this product is used, it needs to add a certain amount of water or ceramic printing paste printing oil, and stir it into a uniform glaze slurry. Then spray and print on the ceramic tiles, and other ceramic processes, and then fire at 1000-1200 ° C to produce golden yellow metallic luster glazed ceramic products.

[0030] This product adds golden yellow pearlescent pigments to the ceramic glaze to ensure that the thermal stability of the mica pearlescent powder in the golden yellow pearlescent pigments is increased to above 1100°C, so that the products that can be fired once at a high temperature of 1000-1200°C present a beautiful golden yellow color.

Abstract

The invention discloses a golden metallic luster glaze which is made by mixing a ceramic glaze material and a golden pearlescent pigment. The glaze is made from 40-90% of the ceramic glaze material and 10-60% of the golden pearlescent pigment by weight. The golden pearlescent pigment is added to the ceramic glaze material to ensure that the thermal stability of mica pearl essence in the golden pearlescent pigment increases to over 1100 DEG C, therefore, products which can be made by burning at high temperature of 1000-1200 DEG C can show beautiful golden color.

Description

technical field [0001] The invention relates to a golden-yellow metallic luster glaze for manufacturing ceramic tiles, sanitary ware and porcelain with golden-yellow appearance effects and a preparation method thereof. Background technique [0002] Metal glaze is a kind of ceramic glaze with special decorative effect that has gradually emerged in recent years. The glazed tiles added with metal glaze have a metallic effect on the surface under the irradiation of light, showing a magnificent effect. [0003] At present, the existing metal glazed tiles are mainly prepared by the following three methods: 1) by introducing heavy metal oxides such as lead, nickel, manganese and copper into the glass frit, and introducing the frit into the ceramic glaze, After firing, the glaze has a metallic luster. 2) Gold, silver, platinum and other precious metals are electroplated or baked at low temperature on the surface of glazed tiles to obtain a shiny metal surface; 3) By introducing Li ...
