Porcelain glaze prepared by utilizing waste porcelain and manufacturing method thereof

Abstract

The invention relates to a porcelain glaze prepared by utilizing waste porcelain. The porcelain glaze consists of the following components in percentage by weight: 8-20% of waste porcelain powder, 8-12% of kaoline, 5-7% of talc, 1-2% of barium carbonate, 6-11% of ground calcium carbonate powder, 3-8% of zinc oxide, 1-5% of dolomite, 15-25% of quartz and 10-30% of feldspar. A manufacturing method of the porcelain glaze comprises the following steps: washing old porcelain with water, after dust removal and drying, crushing, and putting the components in a ball grinding mill, adding an appropriate amount of water, ball-milling for 20 h, adding manufactured waste porcelain powder for combination and regrinding for 2 h, and standing to obtain glaze slip. The utilization ratio of the glaze slip prepared by the method for using the waste porcelain can be up to about 20%. The waste porcelain selected and used in the method takes the place of a portion of quartz, feldspar and some high-lead raw materials, and thus the production cost of porcelain raw materials is greatly reduced; meanwhile, the environmental pollution is effectively reduced, the waste porcelain is sufficiently and reasonably utilized, and the waste is turned into wealth; the glaze slip completely meets the technological requirements of the glaze for porcelain for daily use or porcelain for artistic, and accords with all quality indexes.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and in particular relates to enamel prepared from waste porcelain and a manufacturing method thereof. Background technique [0002] In recent years, our country is in the stage of vigorously developing the economy. Both industrial production and people's lives have produced more and more waste residues. Most of the traditional methods of disposing of waste residues are landfills. Pollution of the environment; for example, the waste residue in the production of daily-use ceramics is mainly waste porcelain, waste gypsum, waste recycling mud, etc.; waste porcelain is facing an extremely difficult dilemma as garbage, because waste porcelain has high hardness, cannot be incinerated, and is not easy to be weathered, etc. Features; At present, most ceramic manufacturers still use general industrial waste to landfill waste porcelain, which has a great impact on the environment, prevents resourc...

[0002] In recent years, our country is in the stage of vigorously developing the economy. Both industrial production and people's lives have produced more and more waste residues. Most of the traditional methods of disposing of waste residues are landfills. Pollution of the environment; for example, the waste residues in the production of daily-use ceramics are mainly waste porcelain, waste gypsum, waste recycling mud, etc.; waste porcelain is extremely difficult to deal with as garbage, because waste porcelain has high hardness, cannot be incinerated, and is not easy to be weathered, etc. Features; At present, most ceramic manufacturers still use general industrial waste to landfill waste porcelain, which has a great impact on the environment, prevents resources from being reused, and seriously wastes resources; this case focuses on the recycling of waste porcelain , a new treatment process was proposed, and this case was born from it
