Inner wall crystal-polishing mirror surface ceramic chip and manufacturing method thereof

Abstract

The invention discloses an inner wall crystal-polishing mirror surface ceramic chip and a manufacturing method thereof. The manufacturing method comprises the following steps of extruding ceramic powder by a mould, of which a mould core is provided with convex lines, to form a green tile with concave lines, firing to form a biscuit to obtain a bottom blank layer, pouring a ground glaze layer and an overglaze layer on the bottom blank layer sequentially, and adding a printing layer; pouring transparent or semitransparent glaze on the printing layer to form a transparent or semitransparent glaze layer, and performing glaze firing to obtain a semifinished product, wherein the parts, with concave lines, of the bottom blank layer form concave parts; performing film coating on the whole surface of the obtained semifinished product by using a vacuum ion film-coating machine and then polishing, or performing film coating only on the concave parts by using the vacuum ion film-coating machine and then polishing. According to the invention, the concave parts are directly arranged in the bottom blank layer and the inner surfaces of the concave parts are subjected to film coating, so that a polished crystal tile with metallic luster can be manufactured by taking a ceramic inner wall blank as a bottom blank, the blank of the existing market is filled, and diversity and aesthetic property of the inner wall ceramic chip are enhanced.

Description

technical field [0001] The invention relates to the technical field of ceramic tile manufacture, in particular to a crystal-polishing mirror tile for an interior wall and a manufacturing method thereof. Background technique [0002] Polished crystal tiles are ceramic tiles in which glass ceramics are laminated on the printing layer after printing on the surface of the adobe. There is a pattern between the green body and the glass ceramic layer. The glass ceramic layer can protect the pattern and pass the refraction and transmission of light at the same time. Presents a good decorative effect. Because of its underglaze decoration, high-temperature firing, delicate glaze surface, noble and gorgeous, it is a high-end decorative product and is more and more popular with consumers, so the market sales are increasing. The production of existing interior wall tiles all adopts on-glaze printing. Due to the influence of its manufacturing process, the use of interior wall tiles tends...

Problems solved by technology

However, the existing technology is only suitable for floor tiles with low water absorption rate, and cannot be applied to interior wall tiles. This is mainly because the ceramic interior wall body has a high water absorption rate, and the use of microcrystalline frits is easy to cause turtles in the later stage due to the expansion coefficient. Cracks, so there are no polished crystal tiles with metallic luster on the market at present
