Ultra-wear-resistant polished glaze and preparation method thereof
The invention relates to an ultra-wear-resistant polished glaze and a preparation method thereof. The ultra-wear-resistant polished glaze comprises the following raw materials in percentage by weight:20 to 40% of albite, 5 to 15% of potassium feldspar, 2 to 7% of nepheline, 2-7% of burnt soil, 1-5% of kaolin, 5-10% of quartz, 2-7% of dolomite, 5-10% of barium carbonate, 5-15% of strontium carbonate, 2-7% of burnt talc, 2-7% of zinc oxide, 2-7% of corundum and 1-7% of vanadine. The preparation method comprises the following steps: 1) mixing the raw materials, a dispersing agent and water, putting the obtained mixture into a ball mill for ball milling until a fineness of the mixture is 300 meshes and screen residues are smaller than 0.5 so as to obtain coarse-particle-size glaze polishing slurry; 2) taking a part of the coarse-particle-size glaze polishing slurry, adding a dispersing agent, and performing ultrafine grinding in a nanometer sand mill until a median diameter is less than 200 nm to obtain ultrafine-particle-size glaze polishing slurry; and (3) mixing the coarse-particle-size glaze polishing slurry obtained in the step (1) and the ultrafine-particle-size glaze polishingslurry obtained in the step (2) according to a raw material mass ratio of 1: 2 to 1: 3, putting the obtained mixture into a high-speed dispersion machine, carrying out stirring to obtain ultra-wear-resistant glaze polishing slurry, applying the glaze polishing slurry onto the surface of a ceramic tile, and carrying out drying, firing and aftertreatment successively to obtain a finished high-hardness wear-resistant ceramic tile.
本发明所述一种超耐磨抛釉及其制备方法的原料成分按重量百分比包括：钠长石20‑40％，钾长石5‑15％，霞石2‑7％，烧土2‑7％，高岭土1‑5％，石英5‑10％，白云石2‑7％，碳酸钡5‑10％，碳酸锶5‑15％，烧滑石2‑7％，氧化锌2‑7％，刚玉2‑7％，钒土1‑7％，制备方法包括以下步骤：1)将原料与分散剂和水混合置于球磨机中球磨至细度为300目筛余小于0.5，得粗粒径抛釉浆料；2)取部分粗粒径抛釉浆料，加入分散剂后置于纳米砂磨机中进行超细研磨，至中位径小于200nm，得超细粒径抛釉浆料；3)将步骤1)所得粗粒径抛釉浆料与步骤2)所得超细粒径抛釉浆料按原料质量比为1:2～1:3混合并置于高速分散机中搅拌，得抛釉料浆，其超耐磨，布施于陶瓷砖表面，干燥、烧成和后处理，即可得到高硬度耐磨陶瓷砖成品。
