Problems solved by technology

[0002] At present, a large amount of zirconium silicate is added to the raw glaze for ceramic tiles or raw glaze for sanitary ware in pursuit of whiteness, which not only makes the production cost of raw glaze for ceramic tiles or sanitary ware raw The problem of product defects, at the same time, it is easy to cause high radioactivity of ceramic products, and the secondary precipitation of zirconium silicate particles is less, resulting in the opacification of residual particles cannot be fully exerted

Abstract

The invention discloses a composite zirconium silicate opacifier and its preparation method and application. The composite zirconium silicate opacifier is prepared from materials comprising the following components in terms of mass percentage: zircon sand 65% ~84%, calcined alumina 1%~15%, low-temperature frit 15%-30%; the low-temperature frit is prepared from raw materials including the following components in terms of mass percentage: potassium feldspar powder 25%-35% %, apatite powder 10%-20%, fluorite powder 2%-8%, calcium carbonate 10%-15%, borax 15%-18%, zinc oxide 1%-8%, quartz powder 2%-8% . The glazing L value of the composite zirconium silicate opacifier of the invention is basically above 91, the opacifying effect is ideal, the production cost is reduced, and the radioactivity of the product can be effectively controlled.

Description

technical field [0001] The invention relates to the field of opacifying agents, in particular to a composite zirconium silicate opacifying agent and its preparation method and application. Background technique [0002] At present, a large amount of zirconium silicate is added to the raw glaze for ceramic tiles or raw glaze for sanitary ware in pursuit of whiteness, which not only makes the production cost of raw glaze for ceramic tiles or sanitary ware raw The problem of product defects is also likely to cause high radioactivity in ceramic products, and the secondary precipitation of zirconium silicate particles is less, resulting in the inability to fully exert the opacification effect of residual particles. Contents of the invention [0003] Based on this, it is necessary to provide a composite zirconium silicate opacifier and its preparation method and application to address the above problems. [0004] The specific technical scheme is as follows: [0005] A composite...
