Formaldehyde-removing nano-liquid for tiles and production process for formaldehyde-removing tiles

Abstract

The invention discloses a nano-solution for tiles to remove formaldehyde and a production process of formaldehyde-removing tiles. The nano-solution for tiles to remove formaldehyde includes a porous mineral loaded titanium dioxide composite material and a tile antifouling solution. The porous mineral loaded titanium dioxide composite material is added into the tile antifouling solution to form a mixture. The production process of formaldehyde-removing tiles includes the following steps of: (1) cleaning tile surfaces; (2) preparing a nano-base solution for tiles to remove formaldehyde; (3) conducting casting, daubing and extrusion with a grinding tool; (4) repeating the operation of step (3); (5) adding water to clean the tile surfaces; (6) preparing nano-surface solution for tiles to remove formaldehyde; (7) conducting casting, daubing and extrusion with the grinding tool; and (8) repeating the operation of step (7). The nano-solution for tiles to remove formaldehyde of the invention has a strong formaldehyde adsorption ability, and can realize the purpose of sustained removal of formaldehyde. The production process of formaldehyde-removing tiles of the invention has a low promotion cost, and can be improved on the basis of existing production processes, thus being suitable for popularization and application.

Description

technical field [0001] The invention relates to a formaldehyde-removing material and a ceramic tile production process, in particular to a formaldehyde-removing nano-liquid for ceramic tiles and a formaldehyde-removing ceramic tile production process. Background technique [0002] In the prior art, Chinese patent document CN 101784501A discloses ceramic tiles for removing formaldehyde and its preparation method. By including activated carbon in the structure of the core board, the effect of activated carbon absorbing formaldehyde is maximized, which can overcome the problem of activated carbon in the heat treatment process. The problem of being easily oxidized. The structure of this kind of ceramic tile is completely different from the ceramic tiles that are widely used, and its preparation method is also completely different from the current mature ceramic tile production and preparation methods. Its promotion and application must abandon the existing ceramic tile productio...

[0002] In the prior art, the Chinese patent document CN 101784501A discloses ceramic tiles for removing formaldehyde and its preparation method. By including activated carbon in the structure of the core board, the effect of activated carbon absorbing formaldehyde is maximized, which can overcome the problem of activated carbon in the heat treatment process. The problem of being easily oxidized

The structure of this kind of ceramic tile is completely different from the ceramic tiles that are widely used, and its preparation method is also completely different from the current mature ceramic tile production and preparation methods. Its promotion and application must abandon the existing ceramic tile production methods, which will make the cost of ceramic tile manufacturers Very expensive; and the principle of activated carbon absorbing formaldehyde is physical adsorption. Once the adsorption is saturated, it cannot continue to adsorb formaldehyde, so its ability to adsorb formaldehyde is limited, and it will not have the function of removing formaldehyde after a period of use
