An antibacterial, easy-to-clean, zirconium-free white functional glaze and its preparation method and application

Abstract

The invention discloses an antibacterial, easy-to-clean, zirconium-free white functional glaze, which is composed of a bottom glaze and a top glaze; the raw material of the bottom glaze is 24-30wt% of feldspar, 28-35wt% of quartz, and 8-12wt% of kaolin. %, limestone 15-25wt%, talc 3-6wt%, zinc oxide 3-6wt%, calcium borate 2-6wt%, calcium phosphate 2-6wt%; the surface glaze is transparent glaze, and its raw material composition is feldspar 24 ~30wt%, Quartz 32~38wt%, Kaolin 8~12wt%, Wollastonite 10~15wt%, Talc 3~6wt%, Zinc oxide 3~6wt%, Calcium titanate powder 3~6wt%, composite antibacterial agent 2-5wt%; the composite antibacterial agent is Ag-loaded + , Al 3+ of zirconium phosphate. In addition, the preparation method and application of the above zirconium-free white functional glaze are also disclosed. Through formula design, the invention avoids the use of zirconium ore raw materials and reduces production costs, and at the same time obtains a zirconium-free white functional glaze with good antibacterial performance, easy cleaning performance and high glaze whiteness and gloss, thereby significantly improving the product quality. performance and added value.

Description

technical field [0001] The invention relates to the technical field of zirconium-free opaque functional glaze, in particular to an antibacterial, easy-to-clean, zirconium-free white functional glaze and a preparation method and application thereof. Background technique [0002] Opaque glaze refers to the existence of a second phase (or multiphase) in the glaze layer that is different from the basic glass phase, which causes the incident light to produce complex optical phenomena such as scattering, refraction, and diffuse reflection at the interface of the multiphase, causing light It cannot penetrate through the glaze layer to achieve an opacity (devitrification) effect. Because opalescent glaze has good covering ability and makes the surface of the product appear white and flawless, it effectively improves the aesthetics and added value of the product, so it is widely used in sanitary ware, daily ceramics and other fields. The second phase in opaque glaze can be solid pha...

Problems solved by technology

In addition, some zirconium-containing opaque glaze products (such as toilets in sanitary ware, etc.) are generally used in alkaline environments, because ZrO 2 or ZrSiO 4 React with alkali, make the glaze surface rough and appear pinholes, cause the glaze surface to absorb dirt, increase the difficulty of cleaning the glaze surface, affect the appearance of the product, and also easily breed bacteria (such as Escherichia coli, Glucobacterium, etc.), affecting people's health
