The invention discloses
bone china with high
glaze hardness and a preparation method thereof. The
bone china comprises a synergistic modified basic
glaze, functional small
organic molecules, a silica structure regulating agent, an inorganic structure stabilizer, a melting behavior regulating agent, a dispersing agent, a flatting agent and a defoaming agent, wherein the synergistic modified basic
glaze takes
feldspar,
quartz,
bone ash and
wollastonite as basic glaze minerals; gamma-aminopropyltriethoxysilane and
boric acid are introduced to carry out synergistic structure regulation and control on a
silicon-
oxygen network, and the functional small organic molecule is
adamantane-1, 3-
dicarboxylic acid. The components are prepared into
glazing slurry, the surface of a
bone china green body is coated with the
glazing slurry, and the bone china product with high glaze
hardness is obtained through
drying and high-temperature firing. According to the invention, on the premise of not obviously influencing the gloss and the appearance quality of the glaze surface, the densification of the glaze layer structure is realized, the
wear resistance, the scratch resistance, the
chemical corrosion resistance and the cold and heat cycle resistance of the glaze surface are obviously improved, and the practical value and the popularization prospect are good.
