Soft glaze for glazed tile and glaze preparation method

Abstract

The invention discloses a soft glaze for a glazed tile and a glaze preparation method. The dry material of the soft glaze comprises the following chemical ingredients by mass percentage: 48-53% of SiO2, 11-15% of Al2O3, 6-8% of CaO, 0.5-1.5% of MgO, 2-5% of K2O, 2-5% of Na2O, 0.2-1% of B2O3, 5-8% of BaO, 10-13% of ZnO, 2-3% of ZrO2, less than or equal to 0.2% of Fe2O3, less than or equal to 0.1% of TiO2 and the balance of impurities. A proper amount of aluminum oxide, zinc oxide and calcium-containing material and barium-containing material are added into the formula of the glaze to form a compound matte agent; the zinc aluminum forms spinel at the high temperature, the emulsivity of the glaze is improved, the glossiness is regulated, the high-temperature levelling property of the glaze isregulated, so that the glaze is more smooth and finer. A proper amount of kaolin, the aluminum oxide and the zinc oxide are introduced into the glaze, the chemical composition of the glaze is regulated, the mineral composition of matte calcium, matte barium, matter zinc and the compound matte agent in the glaze is regulated, and the purposes of smooth and fine glaze and low glossiness are fulfilled.

Description

technical field [0001] The invention relates to a glazed surface of ceramics and a preparation method thereof, in particular to a soft glaze material for glazed tiles and a method for preparing the glazed surface. Background technique [0002] With the improvement of material and cultural level and the popularization of environmental sanitation, people's requirements for living environment are getting higher and higher. Glazed tiles are part of the living environment decoration. It is easy to clean, has low surface gloss, and is not easy to cause damage to the eyes due to light. Therefore, research on soft glazes with smooth, smooth surfaces and low gloss is an inevitable requirement for people to improve their quality of life. [0003] Existing common matte glazes either have a rough surface with low gloss, or a smooth glaze with high gloss, neither of which can be used at the same time. There are also newly developed soft glazes on the market, but the one I developed is d...

Problems solved by technology

[0003] The existing common matte glazes either have a rough surface with low gloss, or a smooth glaze with high gloss, and the two must not be both

There are also newly developed soft glazes on the market, but the one I developed is different from theirs, and the effect is not the same. On the basis of the original ordinary matte glaze, they added soft polishing equipment to polish the glaze softly, but Although this kind of soft polishing has low gloss, it has many pinholes, and increases the production process, which greatly increases the production cost, and it is not the most ideal soft glaze effect.

There is also a soft glaze that sprays low-gloss ink on the high-gloss glaze. Although this process is simple to operate, its gloss is also between 30 and 70, and the gloss is too strong.
