AI Technical Summary

Technical Problem

Existing ceramic products have insufficient wear resistance, a hard surface texture, and weak color development, making it difficult to present a bright and full decorative effect and to create a multi-layered porcelain feel.

Method used

By using nano-grade alumina-zirconia composite powder in proportion with high-alumina clay, calcined zinc and other raw materials, combined with a constant-temperature pre-firing process, and optimizing the glazing sequence, a multi-layer microcrystalline structure is formed, which improves the wear resistance and color performance of the glaze.

Benefits of technology

It achieves high wear resistance, high color payoff, and a combination of warm jade-like texture and distinct multi-layered porcelain feel, improving the chemical stability and bonding strength of the glaze, making it suitable for large-scale industrial production.

Abstract

The invention belongs to the technical field of building ceramic glaze, and particularly relates to high-wear-resistance and high-color-development jade chinastone glaze, a glaze surface and a preparation process. The nanoscale alumina-zirconia composite powder is matched with the reasonably proportioned raw materials such as the high alumina and the burnt zinc, the dispersion strengthening effect and the high transparency characteristic of the nanoscale composite powder are utilized, and the synergistic effect of all the raw materials is matched, so that the effects of high wear resistance and high color development of the glaze surface, and the glaze surface has both the warm jade texture and the obvious multi-layer porcelain feeling are achieved; meanwhile, the chemical stability of the glaze is improved, and the defects of the glaze are reduced. According to the preparation process, the glazing sequence is optimized, the constant-temperature pre-sintering step is added, reasonable technological parameters such as ball milling and sintering are combined, and the jade porcelain stone glaze is preliminarily shaped through constant-temperature pre-sintering, so that the phenomena of glaze flowing and glaze mixing in subsequent glazing are avoided, and the multilayer structure and texture of the glaze surface are further strengthened; the effects of improving the bonding strength of the glaze surface and the green body and ensuring the stable performance of the product are achieved.
