preparation example Construction

[0023] The method for preparing ceramic tiles of the present invention is carried out in the following order.

[0024] First, a tile composition is prepared.

[0025] The tile composition is a dry mixture of 40-80% by weight of loess, 0-20% by weight of clay and 5-30% by weight of activated carbon. Addition of clay is optional.

[0026] In consideration of the effect of removing formaldehyde, various substrates may preferably be used in the form of finely ground powder. In particular, it is preferable to use activated carbon which is a finely ground powder having a particle diameter of 0.14 mm (100 mesh) or less.

[0027] Then, 10 to 30% by weight of water is added to the mixture, and the wet mixture is kneaded for extrusion molding.

[0028] Subsequently, the extruded blank tile molding is dried at 60-100° C. for 40-70 minutes.

[0029] Next, bake the dried tile moldings in a continuous calcination furnace with a maximum baking temperature of 600-900° C. for 0.5-20 minute...

Embodiment 1

[0032] 60-80% by weight of loess, 10-20% by weight of activated carbon having a particle diameter of 0.14 mm or less, and 10-30% by weight of water are added, and the mixture is kneaded for extrusion molding. The molded tiles were dried at 60-100°C for 50 minutes and heat-treated at 800°C for a total baking time of 60 minutes to prepare tiles with activated carbon core boards.

Embodiment 2

[0034] Ceramic tiles were prepared in the same manner as in Example 1, except that a glaze having a melting point of 1100° C. and containing 50% by weight of water was coated on the dried shaped tiles between the drying and baking steps. Subsequent baking steps were carried out in the same manner as in Example 1.

Abstract

A tile using an activated carbon, which is excellent as a formaldehyde absorbent, and a preparation process thereof are disclosed. The effect of activated carbon on absorbing formaldehyde is maximized by the activated carbon-in-core structure, in which the problem of activated carbon that is easily oxidized during a heat treatment may be overcome.

Description

technical field [0001] The present invention relates to a functional tile (tile) and a preparation method thereof, more particularly, to a tile for removing formaldehyde and a preparation method thereof. Background technique [0002] In preparing a functional tile for formaldehyde removal using loess or clay, as an added absorbent, various materials such as charcoal, zeolite, diatomaceous earth, or ash may be used. [0003] Related to the above technology, Korean Patent Publication No. 2001-49437 discloses a building material and house using allophane; Korean Patent Registration No. 495571 discloses a building material using fly ash and diatomaceous earth. health tiles; Korean Patent Registration No. 478949 discloses a method of producing a ceramic container containing charcoal prepared from wood chips; Korean Patent Registration No. 301253 discloses a wall panel with a humidity function and its Manufacturing method; Korean Patent Registration No. 677761 discloses a functio...
