Abstract

The invention discloses a formaldehyde-removing ceramic tile and a preparation method thereof. The preparation method comprises preparing a photocatalytic material A, preparing a photocatalytic wrapping material B, preparing a photocatalytic glaze C, preparing a surface glaze D, preparing a polishing liquid E, and applying glazing , drying, sintering, edging and polishing. The preparation method uses photocatalytic materials such as copper-doped bismuth vanadate, platinum-doped titanium oxide, nano-magnesium oxide and nano-zinc oxide to be wrapped by high-temperature resistant alumina and silicon oxide. , used to improve the high temperature resistance of photocatalytic materials, introduce the wrapped photocatalytic materials into photocatalytic glaze and polishing liquid, so that the fired tiles can withstand 10,000 times of washing, and the formaldehyde removal rate is still as high as 82-93 %, has the characteristics of good formaldehyde removal, good durability and good adhesion, etc., and the brick surface is super clean and bright, with a gloss as high as 95-100°. Formaldehyde requirements in the air.

Description

technical field [0001] The invention relates to the technical field of tiles and preparation methods thereof, in particular to a formaldehyde-removing tile and a preparation method thereof. Background technique [0002] With the development of industry and the improvement of people's living standards, people pay more and more attention to health, such as the harm of formaldehyde to the human body. [0003] Wooden floors, wooden furniture, interior wall paint, etc. in the house will release formaldehyde more or less. The problem of formaldehyde residue in inferior products is particularly serious, and the release of formaldehyde is still long-term. If people wait until all the formaldehyde has dissipated before moving in It is practical, so consumers hope to start with tiles that can purify formaldehyde in the air to improve indoor air quality, so tiles with air purification functions on the market have emerged as the times require. One of the existing ceramic tiles with the...
