The invention relates to a method for preparing gold paste instead of porcelain with gold in complex gold sulphide liquid, which comprises the following steps: (1) preparation of aqua regia by 1 volume of concentrated nitric acid and 3 volume of concentrated hydrochloric acid mixture; (2) to take the gold, gold mica powder and aqua regia, the ratio (weight) for 8.5 ~ 9.5:0.9 ~ 1.1:49 ~ 51; (3) were placed in glass melting, using charcoal by heating for 12 to 16 hours, the heating process of aqua evaporation, adding curing resin 12 to 15 parts by weight, and obtaining the composite gold sulphide solution; (4) inspection, packaging, storage. The application of the invention, the composite gold sulphide liquid can be prepared with porcelain instead of gold gold paste, gold water, greatly reducing the content of gold, from the traditional 10% reduced to below 1%, the production cost is greatly reduced, but also saving the precious metal, gold paste, gold water and the application of the composite gold sulphide liquid instead of gold prepared the printing performance, drying rate, firmness, durability, yellow brightness indicators have reached good level.

用于代替瓷用黄金膏中黄金的复合硫化金液的制备方法
本专利技术涉及陶瓷装饰材料的原材料的制备方法,尤其涉及用于代替瓷用黄金膏中黄金的复合硫化金液的制备方法。
技术介绍
黄金膏、黄金水至今仍是瓷器、精陶和玻璃制品装饰用的重要材料之一,但传统的黄金膏、黄金水的制备,为了达到较理想的装饰效果,一般都需含有10%的黄金,由于黄金属于贵重金属,价格昂贵,使其生产成本高,且浪费贵重金属,因此也使其推广应用受到限制。
技术实现思路
为克服上述不足,本专利技术的目的在于提供一种用于代替瓷用黄金膏、黄金水中黄金的新型材料的制备方法,且与传统黄金膏、黄金水的装饰效果一样,但其黄金的含量大大减少,生产成本大大降低。本专利技术解决其技术问题所采用的技术方案是:用于代替瓷用黄金膏中黄金的复合硫化金液的制备方法,其特征在于:包括以下步骤:(1)王水的制备:由1体积的浓硝酸和3体积的浓盐酸混合而成;(2)取金云母、黄金粉和王水,其配比(重量份)为8.5~9.5:0.9~1.1:49~51;(3)放置于玻璃器皿中进行加热熔化,采用木碳进行加热12~16小时,加热过程王水蒸发,再加入硫化树脂12~15重量份,即制得复合硫化金液;(4)检验、包装、入库。应用本专利技术,该复合硫化金液可代替黄金来制备瓷用黄金膏、黄金水,黄金的含量大大减少,由传统的10%降低为1%,生产成本大大降低,也节约贵重金属,满足日用陶瓷及工艺陶瓷制品装饰的需要,且应用该复合硫化金液代替黄金制得的黄金膏、黄金水,其印刷性能、干燥速度、牢固度、耐磨度、黄亮度等指标均达到较好水平。具体实施方式实施例:用于代替瓷用黄金膏中黄金的复合 ...
