Abstract

The invention discloses a diatomite ceramic mud and a diatomite ceramic product thereof. The diatomite ceramic mud is composed of the following components in percentage by weight: 38-53% of diatomite, 30-42% of kaoline, 2-4% of alumium oxide, 1-2% of borax glass, 1-4% of chromic oxide, 7-12% of feldspar, 2-4% of ardealite, 0-3% of pyrophyllite, 0-1% of silica powder and 0-2% of citrate. Compared with the prior art, the formula of the diatomite ceramic mud is obtained by the applicant by virtue of countless tests, the components in the formula function synergistically, and especially, 38-53% of diatomite is added to the formula so that the fired ceramic product is white and clean in glaze, hard and durable in quality, has outstanding adsorption capacity and is capable of effectively absorbing harmful gases in a room, decomposing harmful substances in air, and suppressing bacteria and sterilizing so as to purify the indoor air.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a diatomite ceramic and a preparation method thereof. Background technique [0002] Nowadays, ceramic products are used in various fields, but most of them are made into utensils for storage or decoration materials or for industrial production. The beauty, high temperature resistance and insulation properties of ceramics are widely used. These existing properties of ceramics can no longer be used. Satisfy people's pursuit of high-quality life now. The main component of diatomaceous earth is silicic acid, with countless pores on the surface, which can absorb and decompose odors in the air, and has the functions of humidity control and deodorization. The building materials produced by using diatomite as raw materials not only have the characteristics of non-combustibility, dehumidification, deodorization and good permeability, but also can purify air, bacteriostasis and disinfection, sound...
