High-temperature-resistant corrosion-resistant antifreeze ceramic product and preparation method thereof

Abstract

The invention relates to a high-temperature-resistant corrosion-resistant antifreeze ceramic product and a preparation method thereof, and belongs to the technical field of ceramics. The high-temperature-resistant corrosion-resistant antifreeze ceramic product comprises the following raw materials in parts by mass: 15-20 parts of nepheline orthoclase, 30-38 parts of Liling kaolin, 10-16 parts of Luochuan loess, 10-20 parts of a waste ceramic green body processing material, 5-9 parts of purple sand shale, 4-7 parts of flint clay, 2-4 parts of calcium zirconate, 5-10 parts of andalusite, 10-15 parts of a talc powder, and 9-14 parts of bentonite. Through the study of the ceramic product used raw materials, the ceramic raw material having excellent performance and relatively low cost is obtained; the ceramic product sintered by the preparation method has relatively good hardness and toughness, is not fragile, has relatively good weatherability, and is not easy to discolor; and in addition, a waste ceramic green body is retreatmented, so the matching performance of the waste ceramic green body with other raw materials in secondary recovery is effectively ensured.

[0002] Ceramics is a general term for pottery and porcelain. Most of the ceramic materials are oxides, nitrides, borides and carbides. Common ceramic materials include clay, alumina, kaolin, etc. There are many types of ceramic products, mainly divided into daily-use ceramics , architectural ceramics, sanitary ware ceramics and special ceramics, etc., generally according to the different types of ceramics, different raw material compositions are selected for firing. The main advantage of ceramic products with excellent performance is corrosion resistance, but due to the different ingredients of ceramic products Insufficient, although it has the advantage of high hardness, its toughness is poor, high temperature resistance needs to be improved, and the antifreeze is not good, and small cracks will occur when the temperature is too low. In addition, the corrosion resistance of ordinary ceramic products also needs to be improved. improve

[0003] At present, the production cost of existing ceramic products with excellent performance is relatively high, so their popularization is limited, and there are a large number of discarded ceramic green bodies in Colombian ceramic product manufacturers, and most manufacturers will not carry out waste ceramic green bodies. Secondary recycling is because if the secondary recycling of waste ceramic green bodies is not done properly, it is likely to cause the whole batch of ceramic products to be scrapped again, so the recycling of waste ceramic green bodies is also extremely important
