High-strength ceramic bowl and preparation method thereof

Abstract

The invention discloses a high-strength ceramic bowl and a preparation method thereof. The high-strength ceramic bowl is prepared from the following raw materials in parts by weight: 31-43 parts of white clay, 22-34 parts of emery, 16-28 parts of attapulgite, 14-23 parts of rectorite, 12-18 parts of diabase, 4-7 parts of carbon nano tubes, 3-6 parts of magnesium borate whiskers, 2-3 parts of ferric citrate, 4-8 parts of magnesium silicate, 6-9 parts of polyethyleneglycol, 5-7 parts of acetylated distarch adipate, 3-5 parts of carboxymethylcellulose sodium, 4-6 parts of cane molasses and 5-10 parts of nano antimicrobial gent. The added emery, carbon nano tubes and magnesium borate whiskers are compounded as a strengthening body to not only remarkably improve the hardness and the strength of the ceramic bowl but also improve the wear resistance, the acid and alkali corrosion resistance and the high-temperature resistance of the ceramic bowl. The prepared ceramic bowl is larger than or equal to 1280 N in breaking strength, larger than or equal to 35 MPa in rupture modulus, high in strength, excellent in thermal stability, resistant to acid and alkali corrosion and durable, thereby meeting the market demands.

Description

technical field [0001] The invention relates to a high-strength 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, there have been many materials that can replace porcelain bowls, such as stainless steel, plastic, etc. Compared with bowls made of these materials, traditional ceramic bowls still have low strength and are fragile. However, there are still some disadvantages in the ceramic bowls current...

Problems solved by technology

Today, due to the advancement of science and technology, there have been many materials that can replace porcelain bowls, such as stainless steel, plastic, etc. Compared with bowls made of these materials, traditional ceramic bowls still have low strength and are fragile. In addition, the ceramic bowls currently on the market still have the disadvantage of poor antibacterial and antibacterial performance, which is easy to breed a large number of bacteria, which is not conducive to dietary health and safety.
