Abstract

The invention discloses a green body for a high-strength thin ceramic plate, a high-strength thin ceramic plate and a preparation method thereof. The green body is obtained by pressing and molding green body powder; and the green body powder comprises the following raw materials ins percentage by weight: 4.0%-18.0% of potassium feldspar, 2.0%-8.0% of albite, 16.0%-24.0% of illite, 28.0%-34.0% of calcined aluminum oxide, 2.0%-4.0% of talc mud, 24.0%-30.0% of acicular kaolin and 2.0%-4.0% of bentonite.

Description

technical field [0001] The invention relates to a green body for high-strength thin ceramic plates, a high-strength thin ceramic plate and a preparation method thereof, in particular to a thin ceramic plate comprising a high-strength green body, surface glaze, inkjet printing technology, and protective glaze and a preparation method thereof , belongs to the technical field of ceramic tile manufacturing. Background technique [0002] With the rapid development of architectural ceramics technology in recent decades, my country has become a major producer, consumer and exporter of architectural ceramics in the world. The building ceramics industry has always been considered a high-pollution and high-energy-consumption industry. The rapid development in recent decades has caused many ceramic raw materials such as kaolin to face the problems of over-exploitation and resource depletion. Environmental issues have also attracted more and more attention. Energy saving, consumption re...
