The invention relates to a new type of ceramic glaze used for ceramic surface decoration and its preparation method, which is characterized in that it is a water-borne glaze with permeability prepared by soluble inorganic metal salts, solvents and adjusting additives, and printed on ceramic tiles with bottom glaze and surface glaze by means of ceramic surface decoration, and then printed on ceramic tiles with bottom glaze and surface glaze. Spraying water to aid infiltration and firing in roller kiln. The firing temperature is 1080 ~1200 C and the firing period is 40~85 minutes. The invention is suitable for surface decoration of ceramics and uses various salts to react with glaze to colour. The advantages of this method are that the cost can be reduced by about 20% compared with that of foreign imports, and it can completely replace imported products. It has broad market economic benefits. In the process of production and application, the adjustability and controllability of the method are improved, and the pattern of the product is richer and more diversified, with a hierarchical and three-dimensional sense.

一种应用于陶瓷表面装饰的新型陶瓷釉及其制备方法
本专利技术涉及陶瓷生产
,更具体的说是设计一种应用于陶瓷表面装饰的新型陶瓷釉及其制备方法。
技术介绍
陶瓷表面装饰技术被称为是一种有重大实用价值的″直接写技术″,具有设备简单、沉积更细的图形、环境友好等优势。随着数字化技术的发展与普及,陶瓷表面装饰技术在陶瓷工业领域逐渐得到应用,较丝网辊筒印花,喷墨打印具备许多无可比拟的优势,它能在较短时间内达到要求,适合陶瓷装饰个性化、多花色,甚至完成一些高难度无法用丝网辊筒花机实现的花色图案。采用这种新型陶瓷表面装饰工艺生产的陶瓷砖,其表面构图、色彩与纹理将会产生突破性的进展,它是继辊筒印花设备后,瓷砖生产领域的又一重大技术突破。高性能、能顺利喷印的陶瓷釉料墨水是陶瓷表面装饰技术在陶瓷上应用的基础,目前国内采用的陶瓷表面装饰釉料均为表面装饰方法,无法在抛光砖上实现装饰,且采用国外进口产品,价格昂贵。现在市面上生产的渗透釉产品大都通过对可溶性金属盐增稠成釉料,再采用丝网印花技术、设备印制于陶瓷坯体表面,其缺点在于纹理细腻度不够、图案千篇一律,没有变化,图案及颜色受印花机限制最多不过三、四种。专利200910311821.6提出了一种陶瓷陶瓷表面装饰用棕色颜料及其制备方法。是将原料细化并混合均匀,1100~1300℃烧成,使用超细设备对颜料粗品进行超微细化处理;采用分级设备处理超微细化粉体,分离超微细化粉体得到成品。专利200910311976提出了一种陶瓷陶瓷表面装饰用锆铁红色颜料的制备方法。是将原料和矿化剂加水配成混合液,将混合液通过喷雾干燥造粒,得到粉粒,将粉粒在 ...
