AI Technical Summary

Technical Problem

While existing technologies improve the static mechanical properties of ceramics, they fail to effectively enhance dynamic impact toughness and surface wear resistance. Furthermore, the processes are complex and costly, fail to achieve synergistic strengthening of the body and glaze, have insufficient antibacterial properties, and are resource-dependent and environmentally unfriendly.

Method used

Potassium feldspar, sodium feldspar, quartz, kaolin, zirconium silicate, pre-composite reinforcing fibers and biomass-derived carbon sources are used as the main raw materials. The green body and glaze slurry are prepared by combining spodumene, calcined zinc oxide, pre-sintered calcium phosphate powder and nano-tin antimony oxide. The green body and glaze are integrated and synergistically strengthened by gradient sintering, avoiding the use of rare earth and precious metals.

Benefits of technology

This process produces ceramic products with high flexural strength, high impact toughness, high surface hardness, wear resistance, and long-lasting antibacterial and easy-to-clean properties, reducing production costs and achieving synergistic enhancement of the body and glaze, while meeting environmental protection requirements.

Abstract

The invention discloses daily high-strength environment-friendly ceramic and a preparation process thereof, and particularly relates to the field of ceramic materials, and the preparation process comprises the following steps: S1, preparation and molding of green body powder, S2, preparation of multifunctional glaze slip, and S3, glazing and sintering. By introducing the pre-compounded reinforced fiber, the SiO2-Al2O3 coating on the surface of the pre-compounded reinforced fiber and the ceramic matrix form strong interface bonding at high temperature, so that the comprehensive mechanical property of the green body is improved, the load is effectively transmitted and dispersed, and meanwhile, the fiber has remarkable toughening and impact resisting effects; due to the addition of the biomass derived porous carbon powder, the fracture toughness and thermal shock resistance of the material are further improved through the pore-forming and buffering effects of the biomass derived porous carbon powder; while high bending strength is maintained, impact toughness is improved in a breakthrough manner, and the composite material is more suitable for collision scenes in daily use.
