High-whiteness ceramic large plate and preparation method thereof
The invention discloses a high-whiteness ceramic large plate and a preparation method thereof. The high-whiteness ceramic large plate comprises the following effective components in parts by weight: 40-130 parts of a hard material, 24-90 parts of a soft material; 0-1.5 parts of zirconium silicate, 0.1-1.5 parts of a green body whitening agent, and 0.3-4 parts of an auxiliary agent. The preparation method comprises the following steps: sequentially carrying out ball milling, sieving for iron removal, powder spraying, green brick pressing, drying, glazing, ink-jet printing, sintering and polishing on the effective components to obtain the high-whiteness ceramic large plate. According to the invention, the high-whiteness ceramic large plate is fine in component granularity, good in dispersity, strong in covering power, good in whitening performance and small in color uniformity deviation; the use amount of zirconium silicate is greatly reduced, and the whiteness of the prepared large plate can exceed that of a large plate product which is whitened by using zirconium silicate conventionally; while whitening, the radioactivity of the product is reduced, so that the ceramic body prepared by the method has the advantages of high whiteness and no radioactivity after being fired; and the product performance, the environmental protection performance and the economic benefit of the large ceramic plate are comprehensively optimized, production and preparation of the large high-whiteness ceramic plate are more reasonable, and the large high-whiteness ceramic plate is suitable for large-scale popularization.
本发明公开了一种高白陶瓷大板及其制备方法，高白陶瓷大板包括按重量份计的有效组分：硬质料40‑130份；软质料24‑90份；硅酸锆0‑1.5份；坯体增白剂0.1‑1.5份；辅剂0.3‑4份；制备方法为将有效组分依序进行球磨、过筛除铁、喷粉、压砖坯、干燥、施釉、喷墨印花、烧成和抛光步骤，得到高白陶瓷大板；其组分粒度细、分散性好、遮盖力强，增白性好，颜色均匀偏差小；大大降低了硅酸锆的使用量，其制备的大板白度可以超越常规使用硅酸锆增白的大板产品；在增白的同时，降低了产品的放射性，故采用本发明制备的陶瓷坯体烧成后具有白度高无放射性的优点；本发明综合优化了陶瓷大板的产品性能、环保性能、经济效益，使高白度陶瓷大板的生产制备更合理，适合大规模推广。
