Method for photochromic low temperature antique glaze and preparing method thereof

Abstract

The invention discloses a photochromic low temperature antique glaze and a preparing method thereof. The preparing method comprises the steps of: A, preparing low temperature frit; B, preparing glaze, mixing low temperature frit, colorant, potassium feldspar, quartz, calcite, talc, calcium phosphate, photochromic compounds and antibacterial composite to obtain the mixing powder, putting sodium tripolyphosphate and carboxymethyl cellulose into powder and mixing the powder evenly, fine grinding, and then adding water so as to obtain the glaze; C, applying the glaze evenly on the body, and then putting the body into the reducing atmosphere furnace, cooling the natural glaze to room temperature after heat preservation, and the photochromic low temperature antique glaze is obtained. Compared with the prior antique glaze, the method has the advantages that the ingredients are scientific, the preparing method is reasonable.

Description

technical field

[0001] The invention relates to the technical field of ceramics, in particular to a photochromic low-temperature antique glaze and a preparation method thereof. Background technique

[0002] Bacteria and mold, as pathogenic bacteria, are very harmful to humans, animals and plants, affecting people's health and even life-threatening, and bringing significant economic losses. Therefore, the research on antibacterial materials and their products has attracted people's attention day by day, and the demand for antibacterial products will constitute a huge market.

[0003] Photochromism refers to photochromism caused by different light sources and color changes caused by physical phenomena such as reflection, refraction and interference. Photochromic materials are divided into organic photochromic materials and inorganic photochromic materials, among which inorganic photochromic materials are less studied, mainly including transition metal oxides, metal halides an...
