Preparation method for plating nanogold on ceramic surface
The invention belongs to the technical field of ceramic preparation, and particularly relates to a preparation method for plating nanogold on a ceramic surface. The invention discloses a preparation method for plating nanogold on a ceramic surface. The preparation method comprises the following steps: S1, coating a sintered ceramic surface with gold water, and annealing to prepare a transition layer; s2, preparing nanogold on the ceramic surface on which the transition layer is formed through vacuum evaporation; and S3, carrying out vacuum annealing on the ceramic on which the nanogold is formed to improve the binding force of a gold-plated layer so as to obtain a finished product. According to the preparation method for plating the nanogold on the ceramic surface, the transition layer is prepared by ingeniously utilizing the gold water technology, and the high-purity nanogold can be formed on the ceramic surface in combination with the vacuum evaporation technology. And secondly, the ceramic surface is plated with nanogold, heavy metal pollution and metal organic matter black spot defects are avoided, the glossiness is better, and the quality is higher. In addition, the nanogold ceramic prepared by the method can reduce the concentration of cyanide in a solution, has antibacterial and toxicity-reducing effects, and is suitable for the field of high-end domestic ceramics.
本发明属于制陶技术领域，具体涉及一种陶瓷表面镀纳米金的制备方法。一种陶瓷表面镀纳米金的制备方法，包括以下步骤：S1.在已烧成的陶瓷表面涂覆金水后退火制备过渡层；S2.在已形成过渡层的陶瓷表面通过真空蒸镀制备纳米金；S3.对已形成纳米金的陶瓷进行真空退火，提高镀金层结合力，制得成品。本发明陶瓷表面镀纳米金的制备方法，通过巧妙利用金水技术制备过渡层，结合真空蒸镀技术，在陶瓷表面可形成高纯度纳米金。其次，本发明陶瓷表面镀纳米金，没有重金属污染，无金属有机物黑点瑕疵，光泽度更好，品质更高。另外，本发明制备的纳米金陶瓷可以降低溶液中氰化物的浓度，具有具有抗菌降毒效果，适用于高端日用陶瓷领域。
