Problems solved by technology

[0003] There are many flashing techniques on the glaze of porcelain tiles, but most of them are on-glaze techniques (starlight glaze, mica flakes, dry diamonds), which cannot be fully polished, so they are not suitable for fully polished products.
There are also some in-glaze flashing techniques such as (chrome crystallization) and the use of high-temperature alloy metal particles (nickel-based alloys) mixed in the glaze to achieve a flashing effect, but the material used for this type of flashing effect has a color that will affect the pattern on the surface of the product effect, so the scope of use has greater limitations

Abstract

The invention discloses a preparation method of a polished porcelain glazed tile with a flashing effect. The preparation method comprises the following steps of S1, mixing high-purity zircon sand andcrystallized frit dry particles to obtain glaze A; S2, taking marble polished glaze or transparent dry granular glaze as glaze B, and mixing the glaze A and the glaze B to obtain mixed glaze; S3, preparing a porcelain tile green body, and drying the porcelain tile green body; S4, applying a cover glaze to the porcelain tile green body dried in the step S3, performing ink-jet printing, and then sequentially applying a protective glaze and the mixed glaze; S5, drying the porcelain tile green body coated with the protective glaze and the mixed glaze in S4 in a drying kiln at 150-200 DEG C, and firing the porcelain tile green body by using a conventional porcelain tile firing method to obtain a semi-finished porcelain tile; and S6, polishing the semi-finished porcelain tile prepared in the S5.The preparation method adopts multiple reflection, dispersion and refraction methods of crystals in the glaze to realize the flashing effect, and meets the market demand.

Description

technical field [0001] The invention relates to the technical field of preparation of porcelain glazed tiles, in particular to a method for preparing polished porcelain glazed tiles with flashing effects. Background technique [0002] The common processes for the surface of high-temperature (≥1180°C) porcelain tiles to shine under the light include starlight dry granules (starlight glaze), flashing mica flakes, diamond dry granules, metal dry granules and crystal sand dry granules. The material is sprayed on the brick surface and fired at a high temperature, through the physical characteristics of the material itself for strong reflection of light and the basic glaze surface with no reflection or weak reflection (dry crystal sand can be used for full-polish products with a temperature of ≦85°) to form light The specular reflection is poor to achieve the flash effect and enhance the product decoration. [0003] There are many flashing techniques on the glaze of porcelain til...
