Method for preparing anion glazed porcelain tiles

Abstract

The invention discloses a method for preparing anion glazed porcelain tiles. The method comprises the steps of preparing unburnt tile bodies and an anion glaze finishing material, coating surfaces ofthe unburnt tile bodies with the anion glaze finishing material, and then carrying out burning by a kiln, thereby obtaining the anion glazed porcelain tiles. The method is characterized in that the unburnt tile bodies are prepared through subjecting raw materials for preparing the unburnt tile bodies to mixed ball-milling, carrying out aging and carrying out molding. The raw materials for preparing the unburnt tile bodies comprise the following ingredients in parts by mass: 30-35 parts of kaolin, 10-15 parts of quartzite, 5-8 parts of fly ash, 10-15 parts of potassium feldspar, 20-30 parts oftalcum mineral powder, 2-3 parts of silica nanopowder, 2-3 parts of germania nanopowder, 5-8 parts of pearl powder and 5-8 parts of zeolite powder. The anion glazed porcelain tiles are natural, odorless, environmentally friendly and safe and are free of toxic or side effects, and the production preparation process is relatively simple and is low in preparation cost.

Description

Technical field: [0001] The invention belongs to the field of preparation and processing of ceramic tiles, and relates to a method for processing glazed tiles, in particular to a method for preparing negative ion glazed tiles. Background technique: [0002] With the continuous improvement of social development and industrial technology, people's living standards are constantly improving, and people's requirements for living environment are also constantly improving. The existing ordinary decoration materials such as ordinary ceramic tiles will have a certain impact on the indoor environment. The low-quality ceramic tiles may even produce radioactive substances on the human body, causing harm to the human body living here. Therefore, various functional ceramic tiles have emerged as the times require, such as negative ion tiles. [0003] Negative ions, also known as "air vitamins", can promote the synthesis and storage of vitamins in the human body, strengthen and activate the...

Problems solved by technology

There is also a high-temperature-resistant rare earth material powder containing indium in the raw material of "A Negative Ion Ecological Ceramic Brick and Its Preparation Method" with the Chinese patent application number CN201310389173, and indium is a rare metal element with certain toxicity and has a small amount of stock. , not suitable for large-scale industrial use

At the same time, the products that can generate negative ions in the above two invention patent applications are only in the glaze layer or green body layer of ceramic products, and the preparation process requires high requirements, and even requires calcination at high temperature and vacuum.
