Abstract

The invention discloses a super-large-sized thin porcelain plate with antibacterial function and a preparation method thereof, comprising the following steps: A. preparing a green body powder for a super-large-sized thin porcelain plate according to a conventional method; B. preparing a super-large porcelain plate according to a conventional method. Base glaze and polishing glaze for thin porcelain plates; C. Preparation of composite antibacterial functional materials; D. Green body powder cloth and mold-free pressing; E. Automatic green body cutting; F. Green body drying; G. Baking ; H, apply the base glaze for super-large and thin porcelain plates; I, dry again; J, inkjet printing; K, apply polishing glaze for super-large and thin porcelain plates; L, dry for the third time; M, burn Cheng; N, edging; O, preparation of composite antibacterial functional film on the surface of ultra-large thin porcelain plate. The beneficial effect of the present invention is to provide an ultra-large-sized thin porcelain plate with antibacterial function and its preparation method, which solves the problem that the traditional thin porcelain plate body is easily damaged and the green body is damaged after using a water-containing decoration process such as wet glaze. Defects such as "water ripples", "frames" and "glaze curtain wires" that appear after surface glazing, by preparing composite antibacterial functional films on the surface of ultra-large thin porcelain plates, endow ultra-large thin porcelain plates with excellent antibacterial functions.

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...
