Abstract

The invention relates to a ceramic liner and belongs to the technical field of ceramic material production. The ceramic liner comprises the following components in parts by weight: 3-8 parts of barium carbonate, 0.01-0.03 parts of copper oxide, 0.005-0.01 parts of cobalt oxide, 5-10 parts of zinc oxide, 1-5 parts of boric acid, 20-35 parts of calcite, 5-10 parts of kaolin, 3-8 parts of aluminum oxide, 35-55 parts of quartz, 3-8 parts of potassium nitrate, 3-8 parts of sodium carbonate and 0.5-2.0 parts of antimony trioxide. The preparation method comprises the following steps: weighing the raw materials, uniformly mixing and stirring the raw materials, melting the raw materials in a high-temperature frit furnace at 1400-1500 DEG C for 1.5-2.0 hours, pouring the melted raw materials into a mold for shaping to obtain the ceramic liner, wherein an outwards-protruding metal ring and a water seal ring are enchased at the edge of the top end of the ceramic liner, and the bottom of the ceramic liner is connected with a metal connection layer which is closely matched with a heating plate. Compared with the prior art, the ceramic liner is high in dimensional accuracy, hermetic and reliable, high in thermal efficiency, energy-saving and consumption-reducing, and long in service life.

Description

technical field [0001] The invention relates to a ceramic inner container, in particular to a ceramic inner container and a preparation method thereof, belonging to the technical field of ceramic material production. Background technique [0002] The liner is a must for household appliances such as rice cookers. However, the traditional liner has low thermal efficiency and short service life, which is not suitable for the development of electrical appliances. [0003] Taojing liner is a new technology applied to rice cookers and other household appliances. "Taojing" technology overcomes the technical difficulties of melting point, difficulty in combining two materials, and non-fitting of materials in previous ceramic surface treatment technologies, making the surface of rice cooker liners successful. A layer of ceramic material is attached to the ground, and at the same time, the performance of the traditional inner tank is improved by using the natural non-stick perfor...
