Problems solved by technology

At present, the semiconductor powder added to the ceramic blank generally adopts single or composite powders such as zinc oxide, tin oxide or antimony oxide, and needs to be added in a certain proportion, such as the introduction of patent CN102030519B, which needs to add 11% to 35% of tin dioxide , 1% to 9% of antimony trioxide; as described in patent CN102795893B, 30 to 45% of tin dioxide is added, so the cost is very high; The method of wrapping ceramic tile powder with slurry reduces the amount of semiconductor powder, but increases the process and cost of the production process, and increases the technical difficulty of production, so it is not easy to implement

Abstract

The invention discloses an anti-static ceramic tile with a nano-structure on the surface, and a preparation method thereof. The method comprises the following steps: S1, preparing a weak acid with certain solubility according to the requirements of a microstructure on the surface of the ceramic tile; S2, uniformly spraying the weak acid on the surface of the ground and polished ceramic tile by adopting high-pressure atomization equipment, and carrying out surface microstructure modification; S3, cleaning and blow-drying the surface of the modified ceramic tile; S4, preparing an aqueous nano silicon dioxide solution doped with silver particles; S5, coating the surface of the modified ceramic tile with the aqueous nano silicon dioxide solution doped with silver particles in a coating mannerto form a film layer, and baking the film layer; and S6, after baking is finished, cooling to the anti-static ceramic tile. The method has the characteristics of being low in production technical difficulty, easy to implement and high in cost performance.

Description

technical field [0001] The invention belongs to the technical field of industrial ceramics, and in particular relates to an antistatic ceramic tile with a nanostructure on the surface and a preparation method thereof. Background technique [0002] Static electricity is a ubiquitous phenomenon. In various industries, especially those with precision instruments or special environments, it is necessary to take protective measures against static electricity. In terms of decorative materials, there are anti-static decorative boards, wood, conductive paint, etc., and ceramic materials account for a large proportion of decorative materials, so preparing an anti-static ceramic is also the direction of everyone's joint efforts. [0003] At present, there are patents on antistatic ceramics, such as CN103614003B, which provides a method of using semiconductor oxides to add ceramic ink to print on the ceramic surface to achieve antistatic effects; such as patent CN102030519B, which uses...
