Abstract
The invention discloses a matte glaze and a preparation method thereof. The matte glaze comprises the following components by weight: 1-5 parts of zincoxide, 5-15 parts of bariumcarbonate, 0-15 parts of zirconiumsilicate, 10-25 parts of potassiumfeldspar, 10-20 parts of kaolin, 5-15 parts of calcite, 5-15 parts of calcined talcum powder, 20-35 parts of a matte frit and 0.5-1 part of an additive. Specifically, the matte frit comprises the following components by weight: 30-50 parts of SiO2, 15-20 parts of Al2O3, 0.01-0.5 part of Fe2O3, 3-10 parts of CaO, 0.5-5 parts of MgO, 1-5 parts of K2O, 3-10 parts of Na2O, 3-10 parts of ZnO, 0.1-1 part of B2O3 and 10-25 parts of BaO. By introducing the matte frit, the melting temperature of the formula is lowered, the firing range of the formula isbroadened, and the glaze texture achieves a fine matte effect.
Description
technical field [0001] The invention relates to the field of ceramic decoration materials, in particular to a matte glaze and a preparation method thereof. Background technique [0002] Stoneware antique glazed tile (water absorption 0.9%-2.5%) is a kind of ceramic decoration material with modern retro decoration style. In recent years, this category of glazed tiles, which tend to be matte and delicate in texture, has become more and more popular among consumers. Under the current rapid firing (firing time is about 45 minutes) process conditions, the traditional raw glaze formula generally introduces refractory compounds to make the glaze surface in a semi-molten state during firing, and the glaze surface is dull but rough. [0003] In the prior art, in the current ceramic production, the preparation of the glaze is generally to weigh the raw material ingredients and add water ball mill to the required fineness, the required ball milling time is long (up to 10-20 hours), an...
