Low-cost high-performance floor tile polishing glaze and preparation method thereof

Abstract

The invention discloses a low-cost high-performance floor tile polishing glaze which comprises the following components in percentage by mass: 0.2-1.5% of K2O, 0.1-0,8% of Na2O, 13.0% to 15.0% of CaO;3.5% to 5.0% of MgO; 10.0% to 11.5% of Al2O3; 53.5% to 55.5% of SiO2; 0.5% to 2.0% of B2O3; 2.5% to 5.0% of ZnO; 7.5% to 10.0% of BaO and SrO; PbO<0.1%; 0.0% to 1.5% of ZrO2; 0.1% to 0.4% of Fe2O3; 0.01% to 0.5% of TiO2; and Li2O<0.01%. The raw materials are uniformly mixed and stirred and packaged by woven bags to obtain a finished product. According to the low-cost high-performance floor tile polishing glaze and the preparation method thereof, the obtained product has the advantages of super wear resistance, high hardness, acid and alkali resistance, super clearness, good color developmentand the like, and the production cost of the product is relatively low.

Description

Technical field [0001] The invention relates to the field of floor tile glazes, in particular to a low-cost and high-performance floor tile polishing glaze and a preparation method thereof. Background technique [0002] The polished tiles and ordinary crystal floor tiles that were once popular a few years ago have been eliminated after the baptism of the market. The pattern of floor tiles has changed to: low-grade wear-resistant tiles, antique tiles, polished glazed tiles and full-body marble tiles. Among them, polished glazed floor tiles account for the mainstream market. The theoretical basis of polished glazed glaze used in polished glazed tiles is derived from the theory of ordinary glass in "Silicate Ceramics": K2O and Na2O in the glass phase increase reflection, especially Na2O in glass The higher the content of the phase, the more transparent the glass body after firing, but the application of ordinary glass theory to floor tile polishing has both advantages and disadvant...

AI Technical Summary

Problems solved by technology

Disadvantages: 1. Light hair color, easy to eat; 2. Large expansion coefficient; 3. Narrow firing range; 4. As the most important performance index of floor tiles: hardness and wear resistance are too poor

Because its theoretical basis is still within the scope of ordinary glass, it has a narrow firing range: 1. It cannot (or is difficult) to produce in-line with ordinary glaze polishing; 2. It cannot (or is difficult) to produce pure black series Bricks, the reason is that when the black bricks are produced, there are too many micropores suspended in the glaze layer, and the antifouling and brightness are not enough after polishing.
