Complete polishing glaze archaizing brick overglaze and preparation method thereof

Abstract

The invention relates to a complete polishing glaze archaizing brick overglaze and a preparation method thereof. The complete polishing glaze archaizing brick overglaze is prepared from the following raw materials by weight percent: 4-8% of albite, 9-12% of potassium feldspar, 12-15% of calcite, 4-6% of barium carbonate, 6-10% of alumina, 12-15% of burnt talcum, 2-4% of zinc oxide, 2-5% of quartz powder, 9-13% of kaolin, 5-9% of wollastonite and the balance of impurities. The preparation method comprises the following steps: carrying out ball milling in a ratio of weighed raw material to ballstone to ethylene glycol to squeegee oil of 1: (1.8-2): 0.25: 0.3, and simultaneously controlling the fineness degree as follows: the screenings of 325-mesh sieve is 0.3-0.4%; printing on ground glaze and fancy glaze layers through 100-mesh silk screen by using a continuous printing process; and finally, firing through a liquefied gas raceway kiln firing system. According to the invention, the purposes of improving the stability of the process and the quality of the product, reducing glaze material loss in production process, reducing cost and simultaneously avoiding the generation of a screen sticking problem in production are achieved.

Description

technical field [0001] The invention relates to a fully glazed antique brick surface glaze and a preparation method thereof. Background technique [0002] Full polish glaze is a kind of special formula glaze that can be polished on the glaze surface. It is the last glaze applied to antique bricks. At present, it is generally transparent surface glaze or transparent convex pattern glaze, which is applied to full polish glaze. The fully polished glazed tile combines the advantages of polished tiles and antique tiles. The glazed surface is as smooth and bright as polished tiles. The characteristic of its glaze is that it is transparent and does not cover the surface glaze and various pattern glazes under it. When polishing the glaze, only a thin layer of transparent glaze is thrown away, and the transparent convex pattern glaze is a bright spot for full polishing. The convex glaze Through silk screen printing, intermittent convex grain glaze is formed on the brick surface, and...
