Problems solved by technology

[0002] With the opening of the international market, the rapid development of ceramic production in recent years has brought about two practical problems. One is that the prices of upstream products of ceramic production continue to rise, the cost continues to rise, and the pressure on enterprises is great; the other is that with the rapid production volume The increase in waste porcelain has also increased in a large amount, causing serious environmental pollution, and the environmental protection costs of cities and enterprises have increased, which is overwhelmed.

Embodiment Construction

[0016] The present invention will be described in detail below through examples.

[0017] Take some waste porcelain, wash it with water, remove dust, dry it, crush it, and pass it through a 325-mesh sieve to make waste porcelain powder; mix 28.65 kg of quartz, 20 kg of feldspar, 12 kg of kaolin, 3 kg of zinc oxide, and 6 kg of white cloud Calcite and 10 kg of calcite are put into a ball mill, and 63.72 kg of water with a pH value of 7 are added, mixed and ball milled for 20 hours, and the fineness of the ball mill is controlled at 0.1% after passing through a 325 mesh sieve; Combine and grind for another 2 hours, remove the iron from the mill and pass through a 200-mesh sieve to make a glaze slurry; make 0.35 kg of methyl cellulose into a solution with a mass concentration of 5%; then add it to the above-mentioned glaze slurry, stir evenly, and Prepare enamel.

Abstract

The invention provides a ceramic glaze and preparation method from waste ceramic. Wherein, the product comprises: 18~25% waste ceramic powder, 20~30% quartz, 10~20% feldsparú¼8~12% China clayú¼0~5% zinc oxide, 0~10% dolomiteú¼7~15% calciteú¼and 0.2~0.5% methylcellulose. The preparation method comprises: cleaning and dedusting the ceramic powder, drying, breaking, and screening; putting said materials into ball grinder with proper water; screening, adding prepared ceramic powder; grinding and screening to prepare glaze slurry; adding methylcellulose into slurry to mix and obtain the product. This invention reduces cost and pollution.

Description

technical field [0001] The invention relates to an enamel made from waste porcelain and a preparation method thereof. Background technique [0002] With the opening of the international market, the rapid development of ceramic production in recent years has brought about two practical problems. One is that the prices of upstream products of ceramic production continue to rise, the cost continues to rise, and the pressure on enterprises is great; the other is that with the rapid production volume The increase in waste porcelain has also increased in a large amount, causing serious environmental pollution, and the cost of environmental protection in cities and enterprises has increased, which is overwhelmed. Utilization of waste porcelain can reduce environmental pollution and save raw materials, which has long existed in the history of ceramic production, but due to technical reasons, its usage is generally limited to a few percent.
