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.
