Abstract

The invention discloses a thermal insulation ceramic bowl with low heat conductivity coefficient and a preparation method thereof. The thermal insulation ceramic bowl is prepared from the following raw materials, by weight, 27-39 parts of dolomite, 20-30 parts of spodumene, 16-24 parts of vermiculite, 13-21 parts of fluorite, 10-15 parts of asbestos wool, 15-25 parts of magnesite, 14-22 parts of pitchstone, 4-8 parts of alumina hollow microspheres, 7-14 parts of floating beads, 5-8 parts of poly(ethylene oxide), 3-6 parts of sodium humate, 2-4 parts of calcium stearyl lactylate, 4-7 parts of hydroxypropyl distarch phosphate and 6-9 parts of antimicrobial powder. The heat conductivity coefficient of the prepared ceramic bowl is less than 0.3W / m.K. As the heat conductivity coefficient is low and heat-insulating property is excellent, heat conduction between the ceramic bowl and a hand is greatly reduced. Thus, the problem that a previous ceramic bowl is easy to burn hands when holding high-temperature food is well solved.

Description

technical field [0001] The invention relates to a heat-insulating ceramic bowl with low thermal conductivity 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 still have high thermal conductivity and poor heat insulation. The shortcomings of ...
