Bright red glaze and preparation method thereof

Abstract

The invention provides a bright red glaze. The glaze comprises the following raw materials: feldspar, clay, high-boron frit, Mg-Al hydrotalcite, kojic acid dipalmitate, nano zinc oxide, nano copper oxide, manganese carbonate and aluminum hydroxide. A preparation method of the above bright red glaze comprises the following steps: putting the raw materials into a glaze mill according to a ratio, performing grinding, and performing filtering through a 120-140-mesh sieve to obtain a mixed base material; and putting the mixed base material into a glaze mill, performing grinding at 45 r / min for 4-8h, and performing filtering through a 120-140-mesh sieve to obtain the bright red glaze. The bright red glaze prepared by adopting the raw material ratio and the preparation method provided by the present application has a bright and stable color, good gloss, fine texture and good adhesion, a glaze layer prepared by adopting the above glaze has very strong adhesion, and a fired ceramic has a smooth glaze surface, fine texture and a bright and smooth glaze color, and has stronger strength, wear resistance, thermal stability and high-temperature resistance.

Description

Technical field [0001] The invention belongs to the technical field of ceramics, and specifically relates to a bright red glaze and a manufacturing method thereof. Background technique [0002] With the advancement of technology, the texture of ceramics is constantly improving. There are many kinds of ceramic products on the market, but the decoration of existing ceramics is mostly innovative from the shape, and the color glaze still needs to be innovated and enhanced. , To meet the demand for vividness of creation and decoration. [0003] In addition, the gloss of the colored glaze layer of the existing ceramic products needs to be improved, and the colored glaze layer will fall off after being placed for a long time. This is mainly due to the poor stability of the glaze layer and its The bonding of the body is not enough, so it is necessary to propose a bright red glaze with stable color, good gloss and high bonding force with the body. Summary of the invention [0004] Based on...

Problems solved by technology

[0002] With the advancement of technology, the texture of ceramics is also constantly improving. There are many kinds of ceramic products on the market, but the decoration of existing ceramics is still mostly innovative from the shape, and the color glaze still needs to be innovated and enhanced. , to meet the demand for vividness of creation and decoration

[0003] In addition, the glossiness of the colored glaze layer of existing ceramic products needs to be improved, and the glaze layer will fall off after being placed for a long time, mainly because the stability of the glaze layer is poor, and it and the base Therefore, it is necessary to propose a bright red glaze with stable color, good gloss and high bonding force with the green body.
