Whitening glaze slurry for high wear-resistant ceramic, and preparation method thereof

Abstract

The invention relates to a whitening glaze slurry for high wear-resistant ceramic, and a preparation method thereof. According to the present invention, raw materials and water are mixed and ball milling is performed to obtain the glaze slurry, wherein the raw materials comprise, by weight, 14-20 parts of albite, 13-17 parts of limestone, 14-18 parts of quartz, 8-12 parts of frit, 1-3 parts of soda ash, 0.5-2.5 parts of white feldspar, 4-6 parts of a whitening agent, and 0.5-2.5 parts of a wear-resistant agent, wherein the whitening agent is prepared from 40-60 parts by weight of kaolin, 40-60 parts by weight of titanium dioxide, 1-2 parts by weight of calcium stearate, and 1-3 parts by weight of gamma-chloropropyltrimethoxysilane, and the wear-resistant agent is prepared from 2-4 parts by weight of yttrium oxide, 8-12 parts by weight of hydroxyapatite, 8-18 parts by weight of calcined talc, and 0.2-0.4 part by weight of an aluminum zirconium coupling agent; and the whitening glaze slurry has characteristics of reasonable raw material, simple preparation method, low production cost and good performance, and is worthy of popularizing and applying.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a preparation method of whitening glaze slurry for high wear-resistant ceramics. 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 method o...
