Low-cost ultra-white overglaze for porcelain tiles and preparation method of low-cost ultra-white overglaze
The invention relates to a low-cost porcelain tile ultra-white cover glaze. The low-cost porcelain tile ultra-white cover glaze comprises potassium feldspar, albite, ultra-white kaolin, calcined kaolin, calcined talc, nepheline, calcined alumina, ultra-white alumina, quartz, wollastonite, strontium carbonate and zirconium silicate. According to the low-cost porcelain tile ultra-white cover glaze, the radioactivity of a prepared product can be greatly reduced, the use amount of zirconium silicate in the cover glaze is controlled to be 5%-8%, the whiteness is directly increased by adding ultra-white kaolin and ultra-white aluminum oxide, the aluminum oxide content in a formula is increased, the firing temperature of the formula is adjusted, and the whiteness of the glaze surface of the product reaches 70-73 degrees in cooperation with zirconium silicate; meanwhile, 1-3 parts of strontium carbonate is added, so that the glaze surface has good color development, is stable and normal and is suitable for a low-temperature fast firing environment.
本发明一种低成本瓷质砖超白面釉，低成本瓷质砖超白面釉包括：钾长石，钠长石，超白高岭土，煅烧高岭土，烧滑石，霞石，煅烧氧化铝，超白氧化铝，石英，硅灰石，碳酸锶，硅酸锆；所述低成本瓷质砖超白面釉可极大降低所制产品的放射性，将面釉中硅酸锆的使用量控制在5%～8%，通过加入超白高岭土和超白氧化铝直接增加白度，并且提高配方中氧化铝含量，调整配方烧成温度，配合硅酸锆使产品釉面白度达到70～73度，同时添加1～3份的碳酸锶使得釉面发色好且稳定正常，适合低温快烧环境。
