Problems solved by technology

Using petalite feldspar instead of spodumene as the main raw material of heat-resistant porcelain can reduce the water absorption rate of heat-resistant porcelain products, increase the flexural strength, reduce the coefficient of thermal expansion, and improve the overall performance of ceramic heat-resistant products, but then The green body has poor plasticity and is easy to crack. In industrial production, it is difficult to form and dry lithium-permeable feldspar heat-resistant porcelain, which becomes a decisive factor in the production process.

Abstract

The present invention relates to the technical field of ceramic manufacture, and particularly relates to a high-plasticity daily heat-resistant ceramic and a preparation method thereof. The blank body of the high-plasticity daily heat-resistant ceramic is prepared by the following raw materials: kaolin, petalite, talcum powder, spodumene, lithium mica, mullite, bentonite, vesuvianite, amphibole powder, alumina, knar clay, silica, europium oxide, sodium carboxymethyl cellulose and zirconia. The raw material components of the blank body of the high-plasticity daily heat-resistant ceramic are improved, and multiple raw materials are introduced based on the combination of a variety of lithium materials. Therefore, the heat resistance and the plasticity of the ceramic are further improved, so that the blank body of the high-plasticity daily heat-resistant ceramic is better in plasticity. The affinity between the blank body and the glaze is improved. The blank body of the high-plasticity daily heat-resistant ceramic is high in plasticity, and can be molded through grouting, rolling and the like. In this way, the manufacturing process is simple, and the energy-saving and environment-friendly effect is realized. The production cost is low.

Description

technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a high-plasticity daily-use heat-resistant ceramic and a preparation method thereof. Background technique [0002] Due to the large thermal expansion coefficient, poor toughness and wear resistance of traditional ceramics, they are easily broken in high-temperature environments, so their application fields are greatly limited and cannot be used in high-temperature parts, especially in places where cold and heat are frequently alternated. With the development of kitchen utensils technology, the performance of ceramics has been improved, and heat-resistant ceramics have been popularized and used as kitchen utensils. [0003] Existing household heat-resistant ceramics mainly add lithium-containing minerals into the green body. For example, the invention patent with the patent number ZL201110341015.0 discloses a high heat-resistant ceramic. Quartz, kaolin, talc, clay, ...
