Embodiment 1

[0011] Example 1: first crush the clean waste porcelain until the aperture is less than 0.5mm, and then put 40% of waste porcelain powder, 30% of feldspar, 20% of barium carbonate, 4% of limestone, and 6% of kaolin into a ball mill according to the percentage by weight. Then add water of 0.5 times the total weight of raw materials, grind to 0.1% of fineness aperture 0.044mm sieve; after discharging, add water to adjust to a slurry with a mass concentration of 48%, use a 0.063mm aperture vibrating screen to remove grass clippings and coarse particles, and then The iron impurities are removed by a magnetic separator to make enamel. The enamel is applied to the feldspar porcelain body and fired at 1340°C. The enamel is firmly combined with the body and the glaze surface is smooth and matte.

Embodiment 2

[0012] Example 2: first crush the clean waste porcelain until the pore diameter is less than 0.5mm, and then pack 20% of waste porcelain powder, 20% of quartz, 30% of feldspar, 20% of barium carbonate, 4% of limestone and 6% of kaolin according to the weight percentage into the ball mill, then add water 0.5 times the total weight of the raw materials, and grind to a fineness aperture of 0.044mm and 0.1% of the sieve residue; after discharging, add water to adjust to a slurry with a mass concentration of 48%, and use a vibrating screen with an aperture of 0.063mm to remove grass clippings and Coarse particles, and then the iron impurities are removed by a magnetic separator to obtain a finished enamel. The enamel is applied to the feldspar porcelain body and fired at 1300°C. The enamel is firmly combined with the body, and the glaze surface is smooth with a semi-dull waxy luster.

Embodiment 3

[0013] Embodiment 3: first crush the clean waste porcelain until the aperture is less than 0.5mm, then pack 10% waste porcelain powder, 20% quartz, 40% feldspar, 18% barium carbonate, 6% limestone, and 6% kaolin by weight into the ball mill, then add water 0.5 times the total weight of the raw materials, and grind to a fineness aperture of 0.044mm and 0.1% of the sieve residue; after discharging, add water to adjust to a slurry with a mass concentration of 48%, and use a vibrating screen with an aperture of 0.063mm to remove grass clippings and Coarse particles, and then the iron impurities are removed by a magnetic separator to obtain a finished enamel. The enamel is applied to the feldspar porcelain body and fired at 1200°C. The enamel is firmly combined with the body, and the glaze surface is smooth, showing a semi-dull oily luster.

Abstract

The invention discloses a matt porcelain glaze prepared by using waste porcelains and a production method thereof. The matt porcelain glaze is prepared from the following components in percentage by weight: 10 to 40 percent of waste porcelain powder, 0 to 30 percent of quartz, 20 to 40 percent of feldspar, 18 to 25 percent of barium carbonate, 2 to 6 percent of limestone and 6 to 10 percent of kaolin. The matt porcelain glaze can be produced by using the waste porcelains to reduce pollutions caused by the waste porcelains to the environment and reduce the production cost; and the prepared porcelain glaze is well combined with a body to ensure that the matt effect on a glazed surface of a product is obvious, and has a unique decorative effect.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a matt enamel made from waste porcelain and a production method thereof. Background technique [0002] Waste products are unavoidable in the ceramic production process. This kind of ceramic waste products fired at high temperature cannot be degraded under natural conditions. Disposal as garbage will inevitably have a negative impact on the environment. If it can be recycled and reused in ceramic production, environmental pollution can be avoided and zero emissions can be achieved. At the same time, production costs can be reduced through the recycling of resources. [0003] ZL03126502.2 discloses a method of using waste ceramics and the porcelain clay prepared by preparing the following composition: waste porcelain powder 30-60%, plasticizer 5-12%, composite flux 0-20%, Clay 35-55%. Add water at a ratio of 1:0.8 to 1.5, ball mill, remove iron, and dehydrate to become porcelain clay with...
