preparation example Construction

[0062] A method for preparing ceramics, comprising:

[0063] Green body process: digitally position the foil gold effect particles on the surface of the green body, press together with the green body, fire, fully polish, semi-polish or matte polish, to obtain finished ceramics; or

[0064] Underglaze process: On the bricks that have been designed by inkjet, use dry positioning process or wet process to apply foil gold effect particles, and then use spray / spray to apply polished glaze or dry glaze, firing, full polishing, semi-glazing polished or matted to obtain finished ceramics; or

[0065] In-glaze process: Mix the foil gold effect particles with dry glaze or polished glaze evenly, and then spread it on the brick adobe with inkjet design by spraying / spraying, firing, full polishing, semi-polishing or matte polishing, to get the finished product Ceramic; or

[0066] On-glaze process: on the tiles that have been applied with polished glaze or dry glaze, adopt dry positionin...

Embodiment S1

[0087] The S1 foil gold particles are digitally positioned and distributed on the surface of the green body through a digital distributing machine, pressed, fired, and polished.

[0088] The surface of the tiles shows a strong metallic luster and has the most authentic metal texture, highlighting the atmospheric style of the tiles (see figure 1 ).

Embodiment S2

[0090] The compacting machine presses the green body once to form a green body, and uses a silk screen to print S2 gold foil particles on the green body once formed, and then performs secondary pressing, firing, and polishing.

[0091] The special metal pattern formed on the surface of the tiles adds a sense of design to the tiles and improves the grade of the tiles (see details figure 2 ).

Abstract

The invention belongs to the field of ceramics, and discloses gold foil effect particles for ceramic, the ceramic, a preparation method of the ceramic and a glaze. The chemical composition of the sintered gold foil effect particles comprises silicon dioxide, aluminum oxide, barium oxide, sodium oxide, potassium oxide, magnesium oxide, zinc oxide, strontium oxide, chromium sesquioxide, titanium dioxide, copper oxide or iron oxide. According to the gold foil effect particles in some examples, the reflectivity can reach 186%, and the gold foil effect particles have good metal luster and metal texture and highlight the atmosphere style of ceramic tiles; good acid and alkali resistance is achieved, the acid and alkali resistance reaches the GA level or above, and metallic luster is not lost after long-term use; and the compatibility with the existing dry granules and glaze slip is good, and various decorative effects can be obtained by being matched with various dry granules and glaze slip for use and compounding.

Description

technical field [0001] The invention relates to a metal luster effect particle, in particular to a gold foil effect particle for ceramics and a preparation method thereof, a gold foil effect glaze for ceramics, a gold foil effect ceramic and a preparation method thereof. Background technique [0002] The metal surface has a strong light reflection effect and has a unique decorative effect. The metal luster effect is introduced into the ceramic tiles. With the different lighting and viewing angles, it will produce a strong metallic luster, which gives people a visual shock and improves the grade of ceramic tile design. [0003] The traditional metallic luster glaze is generally saturated by one or more transition metal oxides such as Ti, Co, Cr, Mn, Fe, Ni, Zn, Cu, etc. at high temperature, and crystals are precipitated to produce a metallic luster effect. . The existing metallic luster mainly includes yellow, silver, black, copper red, brown and other varieties. There are...
