Abstract

The invention discloses a thermal-shock-resistant environment-friendly domestic ceramic product and a preparation method thereof. The thermal-shock-resistant environment-friendly domestic ceramic product is prepared from the following raw materials in parts by weight: 100-125 parts of mullite powder, 20-27 parts of lithium porcelain stone powder, 12-17 parts of lithium feldspar powder, 30-36 partsof attapulgite clay, 45-60 parts of silicon dioxide fibers and 20-30 parts of silicon-aluminum-magnesium high-strength fibers. The thermal-shock-resistant environment-friendly domestic ceramic product has the advantages of a small thermal expansion coefficient, favorable thermal shock resistance, favorable heat resistance, favorable user experience and a long service life, can be used in a high-temperature environment and a cold / heat alternately-changing environment (thermal shock resistance of 700-20 DEG C) for a long time, and is not easy to crack and the like; and moreover, the thermal-shock-resistant environment-friendly domestic ceramic product has a smooth surface, can be directly used as domestic ceramic, can save the glazing procedure, saves the processing cost, and has favorablestrength and other comprehensive properties.

Description

technical field [0001] The invention relates to the field of ceramic products, in particular to a thermal shock-resistant and environment-friendly daily-use ceramic product and a preparation method thereof. Background technique [0002] Ceramic products are one of the most common utensils in people's daily life. The development history of ceramics is an important part of the history of Chinese civilization. Among them, the invention and development of ceramics have unique significance. With the development of modern science and technology, modern In the past century, many new ceramic varieties have appeared. They no longer use or rarely use traditional ceramic materials such as clay, feldspar, and quartz, but use other special materials, and even expand to the range of non-silicate and non-oxide. , and many new processes have appeared, making ceramics have various special functions. [0003] With the progress and development of society, people pay more attention to the conc...
