Problems solved by technology

However, if the structural color coating is directly prepared on the surface of the ceramic glaze layer after heat treatment, the combination of the structural color layer and the ceramic glaze layer is poor, and it is easy to fall off. If the structural color coating is directly self-assembled on the surface of the ceramic glaze layer before sintering, heat treatment The internal orderly arrangement of the post-structural color layer will be destroyed, so that the structural color layer loses its color

Abstract

The invention discloses a preparation method of an inorganic structural color coating for ceramic glaze. Non-toxic and inexpensive silica is adopted as the material, and tartaric acid, polyethylene glycol, stearamide, glyceryl tristearate, sodium dodecyl sulfate, ethylene bis-stearamide and the like are adopted as the dispersant to prepare the inorganic structural color coating for ceramics. The preparation method has the advantages of simple process, short cycle, simple equipment and low cost, the obtained inorganic structural color coating has high bonding strength and good color saturation,and the coating is high temperature resistant, thereby broadening application of the structural color coating in ceramics.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a preparation method of an inorganic structural color coating for ceramic glazes. Background technique [0002] At present, the preparation methods of structural color mainly include micromachining technology and self-assembly technology. Self-assembly technology has attracted much attention because of its low cost, short cycle, and large one-time preparation area. Self-assembly technology requires colloidal balls to have good monodispersity. Characteristic and narrow particle size distribution, silica colloidal balls or polymer colloidal balls are mostly used. However, if the structural color coating is directly prepared on the surface of the ceramic glaze layer after heat treatment, the combination of the structural color layer and the ceramic glaze layer is poor, and it is easy to fall off. If the structural color coating is directly self-assembled on the surface...
