Problems solved by technology

Although the nano-scale micropores of the humidity-adjusting ceramic tiles can absorb part of the formaldehyde in the air, when the formaldehyde adsorbed by the nano-scale micropores reaches saturation, not only will the formaldehyde no longer be adsorbed, but also the adsorbed formaldehyde may be absorbed when the external conditions change. Released, causing secondary pollution of indoor air

Abstract

The invention discloses a photocatalytic glaze applied to humidity-conditioning ceramic tiles. The photocatalytic glaze comprises the following components by weight: 45-55 parts of low temperature frit, 0.3-1.2 parts of anatase titanium dioxide, 0.5-2 parts of calcium carbonate, 0.5-2 parts of bentonite, 0.5-1.5 parts of a dispersant and 45-65 parts of water. The photocatalytic glaze provided by the invention adopts low temperature frit as the main raw material component, uses bentonite as the glaze suspending agent, takes calcium carbonate as the pore-forming agent, and introduces anatase titanium dioxide as the photocatalyst, realizes photocatalysis properties of low temperature glaze and the porous performance of the glaze layer, and ensures the moisture absorption and liberation functions of humidity-conditioning ceramic tiles.

Description

technical field [0001] The invention relates to the field of architectural ceramics, in particular to functional ceramic glazes. Background technique [0002] With the development of economy and society, people are suffering from indoor air pollution while enjoying modern civilization and social prosperity. Nowadays, most indoor building materials, furniture products and decoration materials contain volatile organic substances that are extremely harmful to human health. If these volatile organic substances cannot be effectively decomposed, it will seriously pollute the indoor air and cause indoor air pollution. The "gas chamber" that people fear. Among them, formaldehyde among the decoration pollutants is the most harmful to the human body and has the longest incubation period. It is known as "the first killer of indoor pollution". Formaldehyde is the main cause of neonatal malformation, childhood leukemia, memory and intelligence decline in adolescents, and has been ident...
