Thermal insulation ceramic bowl with low heat conductivity coefficient and preparation method thereof
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.
