Abstract

The invention discloses an ultra-large-specification thin porcelain plate with antibacterial function, and a preparation method thereof. The preparation method comprises the following steps: A, preparing green body powder for an ultra-large-specification thin porcelain plate according to a conventional method; B, preparing a ground glaze and a polishing glaze for the ultra-large-specification thinporcelain plate according to a conventional method; C, preparing a composite antibacterial functional material; D, carrying out green body powder distribution and mold-free compression molding; E, automatically cutting the green body; F, drying the green body; G, baking; H, applying with the ground glaze for the ultra-large-specification thin porcelain plate; I, drying again; J, carrying out ink-jet printing; K, applying with the polishing glaze for the ultra-large-specification thin porcelain plate; L, carrying out third drying; M, firing; N, edging; and O, preparing the composite antibacterial functional film on the surface of the ultra-large-specification thin porcelain plate. According to the invention, the ultra-large-specification thin porcelain plate with the antibacterial functionand the preparation method thereof are provided, the problems that the green body of the ultra-large-specification thin porcelain plate is prone to damage, and water ripples, frames, glaze curtain pull lines and other defects appear on the surface of the green body after glazing after wet glazing and other water-containing decoration processes are performed on the traditional thin porcelain plateare solved, and the composite antibacterial functional film is prepared on the surface of the ultra-large-specification thin porcelain plate so as to endow the ultra-large-specification thin porcelain plate with the excellent antibacterial function.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to an ultra-large thin porcelain plate with antibacterial function and a preparation method thereof. Background technique [0002] Affected by long-term geological movement and climate change, natural stone is mixed with associated minerals of other colors, forming a high-end, natural and rich decorative effect. As a high-end decorative material, it is favored by people. However, the associated radioactive minerals in some natural stones will cause radioactive hazards to human health; natural stones that have been affected by geological processes and weathering have many defects such as impurities and cracks, which are prone to "pathological changes" and poor performance. In addition, natural stone, as a non-renewable resource, is expensive and difficult to enter the homes of ordinary people; excessive mining and processing of natural stone not only causes the exhaust...
