Development method of medium-high temperature yellow-white super-flat semi-white frit under phosphorus-free condition

Abstract

The invention discloses a development method of medium-high temperature yellow-white super-flat semi-white frit under a phosphorus-free condition, and belongs to the technical field of production of interior wall ceramic tile glaze. The frit comprises 3.3% of special frit 1 for tiles, 3.3% of special frit 2 for tiles, 40.0% of special frit 3 for tiles, 12.5% of special potash feldspar for floor tile glazing, 25.8% of wollastonite, 3.3% of quartz, 4.2% of calcined zinc oxide, 3.3% of calcined alumina powder (corundum powder) and 4.2% of kaolin (dry weight). The invention relates to a novel product prepared from high-grade floor tile polished glaze (high in specific gravity, high in hardness, ultra-clear and good in color development). Under the proper kiln firing condition, after the glazeeffect is polished, the glaze is super bright, super hard, resistant to abrasion, clear and rich in color development, good in glaze slip performance, reasonable in expansion coefficient and quite suitable for being used as a high-grade product by brand ceramic floor tile manufacturers.

Description

technical field [0001] The invention relates to the technical field of glaze production for floor tiles, in particular to how to develop and prepare high-grade superhard practical products for ceramic floor tiles under the condition of appropriate cost. Background technique [0002] People who are engaged in the production and technology of ceramic wall and floor tiles know that the polished tiles and ordinary crystal floor tiles that were popular a few years ago have been eliminated one after another after the baptism of the market. The pattern of floor tiles has become: low-grade wear-resistant tiles, antique tiles, glazed tiles and whole body marble tiles. Among them, glazed floor tiles account for the mainstream market. The theoretical basis of glazed glazed tiles is derived from the theory of ordinary glass in "Silicate Ceramics": K in the glass phase 2 O, Na 2 O enhances the reflection, especially Na 2 The higher the content of O in the glass phase, the more transpa...

Problems solved by technology

Disadvantages: 1. The hair color is light and easy to eat; 2. The expansion coefficient is too large; 3. The firing range is narrow; 4. The most important performance indicators as floor tiles: hardness and wear resistance are too poor

As far as ordinary semi-white frit is concerned, although the price is low and popular, its hair color is lacking and many patterns are distorted. , "red-yellow-blue" three primary colors lack of color
