Abstract

The invention discloses a binder for a ceramic blank and relates to the technical field of ceramic production. Raw materials of the binder disclosed by the invention are safe, nontoxic and healthy, the prepared binder is high in viscidity, good in binding effect, capable of increasing the binding speed of the ceramic blank and convenient to mold the blank, the rapidly molded blank is high in toughness, good in wear resistance and not easy to break after being calcined, and the binder is incapable of changing the performance of the ceramic blank or excessively hardening the ceramic blank.

Description

Technical field: [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a binder for ceramic blanks. Background technique: [0002] Ceramics is the general term for pottery and porcelain. Common ceramic materials are clay, alumina, kaolin and so on. Ceramic materials generally have higher hardness, but poor plasticity. In addition to being used in tableware and decoration, ceramics also play an important role in the development of science and technology. The raw material of ceramics is obtained by quenching the earth's original large resource clay. The nature of clay is tough, it can be molded when it meets water at room temperature, it can be carved when it is slightly dry, and it can be ground when it is completely dry; it can be made into pottery when it is fired to 700 degrees, and it can be filled with water; corrosion. The flexibility of its usage has various creative applications in today's culture and technology. [0003]...
