Ageing cracking resistant ceramic bowl and preparation method thereof

Abstract

The invention discloses an ageing cracking resistant ceramic bowl and its preparation method. The ceramic bowl is prepared from the following raw materials, by weight, 33-47 parts of meerschaum, 25-35 parts of leucite, 22-33 parts of barite, 18-26 parts of nacrite, 15-25 parts of glass flake, 4-8 parts of tea dust, 3-6 parts of calcium hexaboride, 9-16 parts of konjaku flour, 4-7 parts of soya lecithin, 2-4 parts of disodium ethylene diamine tetraacetate, 3-5 parts of poly-aluminum ferric silicate sulfate, 2-3 parts of CITREM, 4-6 parts of alkali lignin and 8-10 parts of antimicrobial powder. With addition of glass flake, tea dust and calcium hexaboride, chemical corrosion resistance and ageing resistance of ceramic tiles can be enhanced. In addition, with addition of konjaku flour, soya lecithin, poly-aluminum ferric silicate sulfate and the like, adhesive stress among mineral particles can be raised, and ageing cracking of ceramic tiles can be prevented effectively. The prepared ceramic bowl has excellent heat resistance, corrosion resistance and ageing resistance, is not easy to crack or break and has long service life.

Description

technical field

[0001] The invention relates to an anti-aging and cracking ceramic bowl and a preparation method thereof, belonging to the field of ceramic materials. Background technique

[0002] As an important part of life, bowls are closely related to people's daily life. They are the most important and indispensable utensils in eating activities. They are especially widely used in China and are a necessity in Chinese eating utensils. my country has used porcelain clay, quartz sand and other raw materials to make fine ceramic bowls since ancient times, and they have been used as eating utensils because of their practicability and aesthetics. Today, due to the advancement of science and technology, many materials that can replace porcelain bowls have appeared, such as stainless steel, plastic, etc. Compared with bowls made of these materials, traditional ceramic bowls have the disadvantage of poor aging resistance. The problem of aging and cracking is prone to occur in t...
