Abstract

The invention relates to the field of ceramic materials, in particular to a corrosion-resistant thermal-insulation ceramic material and a preparation method thereof. The corrosion-resistant thermal-insulation ceramic material is prepared from, by weight, 50 parts of barium titanate, 15 parts of copper calcium titanate, 8 parts of far infrared ceramic powder, 8 parts of nanometer titania, 6 parts of sodium silicate and 0.5 part of polyethylene glycol; the preparation method of the corrosion-resistant thermal-insulation ceramic material comprises the following steps: step 1, uniformly mixing the raw materials; 2, heating and extruding the mixture obtained in the step 1 into a ceramic green body; and 3, sintering the ceramic green body, and naturally cooling to room temperature to obtain the corrosion-resistant thermal-insulation ceramic material. The invention further relates to a preparation device of the corrosion-resistant thermal-insulation ceramic material in the preparation method of the corrosion-resistant thermal-insulation ceramic material. The preparation device for the corrosion-resistant thermal insulation ceramic material comprises a calcining box body, a bearing frame, a transmission mechanism, a shifting mechanism, a control mechanism, a conveying mechanism, an air suction mechanism and a motor.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to a corrosion-resistant and heat-preserving ceramic material and a preparation method thereof. Background technique [0002] Ceramics is the general term for pottery and porcelain. It is a material and various products made of clay as the main raw material and various natural minerals through crushing, mixing, molding and calcination. People invented pottery as early as the Neolithic Age about 8,000 years ago. Porcelain industry is a traditional industry in my country, and ceramic products are the pillar industry and export competitive product of my country's light industry. With the development of society, ceramics occupy an important position in many fields, and are recognized by many consumers, making the application range of ceramics wider and wider. At present, it has been widely used in chemical industry, energy, metallurgy, biomedicine, environmental protection, aerospace ...
