Whitening glaze slurry for high-strength ceramics and preparation method thereof

Abstract

The invention discloses high-strength whitening glaze slurry for ceramic and a preparation method of the high-strength whitening glaze slurry. The glaze slurry is prepared from raw materials and water through mixing and ball milling; the raw materials comprise, in parts by weight, 16-22 parts of potash feldspar, 15-19 parts of calcite, 16-20 parts of quartz, 10-14 parts of frit, 1-5 parts of sodium carbonate, 10-14 parts of calcium carbonate, 0.5-2.5 parts of dolomite, 4-6 parts of a whitening agent and 0.5-2.5 parts of a reinforcing agent, wherein the whitening agent is prepared from 50-70 parts of kaoline, 50-70 parts of titanium dioxide, 1-2 parts of calcium stearate and 2-4 parts of gamma-chloropropyltrimethoxysilane; the reinforcing agent is prepared from, in parts by weight, 10-14 parts of hydroxyapatite, 10-20 parts of calcined talc and 0.2-0.4 parts of an aluminum zirconium coupling agent. The high-strength whitening glaze slurry for the ceramic adopts reasonable materials, a preparation method is simple, the production cost is low, the performance is good, and the high-strength whitening glaze slurry is worth popularization and application.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a whitening glaze slurry for high-strength ceramics and a preparation method thereof. Background technique [0002] Glaze is a glossy glass-like thin layer covering the surface of the ceramic body, and its function is to improve the physical and chemical properties of the body surface. Generally, the surface of the ceramic body is loose and porous, rough and dull, moisture absorption and easy to be stained and other shortcomings affect the mechanical properties of the product, and spraying glaze slurry on the ceramic body can overcome these shortcomings and improve the mechanical properties of the product and increase the strength of the product. , hardness and thermal stability. Based on the role of glaze slurry on ceramic products, the importance of glaze slurry in the ceramic industry is constantly being highlighted and enhanced, and the material and preparation met...
