The present invention relates to a tile having a humidity and humidity control function, and in particular, it can change the color depending on the surrounding humidity so that the humidity can be sensed, and at the same time, the humidity can be controlled by absorbing or releasing moisture according to the humidity , A tile having a humidity and humidity control function capable of exhibiting a deodorizing and adsorbing function.

In winter, air tightness inside the building increases to increase energy efficiency, and as a result, the skin becomes dry, resulting in keratin in part of the body and an itchy area resulting in worsening of atopic skin disease. To prevent this, it was common to place the laundry in the room or to operate the humidifier.

In recent years, attempts have been made to alleviate skin diseases by installing wallpaper, tiles or panels having a humidity control function. When a product having such a humidity control function is installed, condensation on the wall due to moisture absorption can be prevented. However, problems of causing respiratory diseases such as cough, cold, rhinitis or asthma by promoting the growth of fungi or bacteria by high moisture absorption there was.

In addition, even in the summer when the humidity is relatively high, the product suffers from excessive moisture absorption.

In the case of the conventional functional tile or panel having various hygroscopic functions as described above, only the functional surface such as adsorption, deodorization and moisture absorption tends to be emphasized, and the product can be recognized as a proper humidity There was no function. In addition, when a humidifier and a functional product including one of adsorption, deodorization, and moisture absorption are simultaneously used at the same time, pseudomonas aeruginosa, Klebsiella pneumoniae ), Pathogenic microorganisms such as Cladosporium and Alternaria which cause Staphylococcus aureus, allergy and asthma are generated.

Meanwhile, Applicant's Registration Utility Model No. 20-0370971 relates to a moisture-permeable topographic wallpaper, which is made of silica gel, alumino-silicate bead, zeolite or the like, which is coated or immersed with a material having a function of recognizing humidity, Is scratched with a particle size of 20 탆 or less and attached to the uppermost surface of the product to maximize humidity recognition and interior effect. However, this terrestrial wallpaper is disadvantageous in that the humidity control function is not sufficient due to the structural limitation of the wallpaper itself, and the humidity rate is low, so that the humidity of the air can not be sufficiently discerned.

Disclosure of Invention Technical Problem [8] The present invention has been devised in order to solve the problems of the related art as described above, and it is an object of the present invention to provide a humidity control device, The present invention provides a tile having a humidity and humidity control function.

As described above, the tile having a humidity and humidity control function for achieving the object of the present invention is formed by forming a humidity-sensing layer on the surface of a substrate layer in the form of a porous plate, wherein the humidity-sensing layer comprises a cobalt compound, A dye or a compound combined with an alkali metal or an alkaline earth metal, and a humidity-sensitive substance which absorbs moisture in the air and discolors.

As the cobalt compound, cobalt chloride and the known iron compound may be used.

The organic dyes may be selected from the group consisting of neural red, phenol red, bromothymol blue, phenolphthalein, cresol red, thymol blue, bromocresol green, bromocresol purple, bromocresol blue or methyl red or a mixture of two or more thereof Group may be used.

Compounds that are capable of recognizing the conventional humidity as the compound bonded to the above alkali metal or alkaline earth metal may also be used.

The substrate layer on the porous plate may be formed of at least one selected from the group consisting of diatomaceous earth, clay, loess, clay, alopen, peat, silicic acid-based materials including silicon dioxide, calcium oxide, calcium hydroxide, calcium carbonate, charcoal, activated carbon, bentonite, vermiculite, sepiolite, , Pozzolan, or microcement, into a plate shape.

A resin layer may be further laminated between the humidity-perceptible layer and the substrate layer. The resin layer is made of at least one resin selected from an epoxy resin, an acrylic resin, a polyethylene, a polyurethane, a phenol resin, a melamine resin or a polyvinyl chloride. A balance layer may be further formed on the back surface of the substrate layer. A surface protective layer having moisture permeability may further be laminated on the surface of the humidity-sensing layer. A pattern print portion may further be formed on the surface of the humidity sensing layer.

Also, the humidity control panel according to the present invention is configured such that a plurality of humidity control tiles having a humidity and humidity control function are fixed to a panel substrate on which a plurality of tile fixing grooves are formed.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, as described above, the tile having the humidity and humidity control function for achieving the object of the present invention has the humidity-sensitive layer 12 on the surface of the porous substrate layer 11 And a moisture-sensing material for absorbing and discoloring moisture in the air, such as a compound in which the moisture-sensing layer 12 is bonded to a cobalt compound, an iron compound, or an alkali metal or an alkaline earth metal .

The porous substrate layer 11 contains a large number of pores therein and condensation of moisture into the pores forms a moisture-containing or impregnating function. Especially, in order to facilitate fixing to a wall or the like, a thin plate- . Such a shape is generally referred to as "tile ", and unless otherwise specified in the present invention, pores are exposed on the surface without treatment such as glazing. In the case of a conventional decorative tile, the surface is treated with a glaze to improve the decorative property, and then the glaze is changed into a glassy material so that the surface is smooth and glossy. In contrast, . However, it will be appreciated by those skilled in the art that, in the case of the tile according to the present invention, a smooth and glossy surface can be formed by treatment of the glaze on the portion where the inhaling layer is not formed.

The formation of the humidity-sensing layer 12 on the surface of the base layer 11 may be formed by distributing the humidity-sensing substance on the surface of the base layer 11. For example, the humidity-perceptible layer 12 may be impregnated between the pores of the substrate layer 11 by a method such as dropping or spraying a solution in which the humidity-sensitive substance is dissolved onto the surface of the substrate layer 11 1, the humidity-sensitive layer 12 containing the moisture-sensitive substance can be formed on the surface side of the base layer 11. However, the present invention is not limited thereto. The viscosity of the binder may be adjusted by mixing a binder for ordinary paints with the humidity-sensitive material and adding a solvent for common paint to the surface of the base layer 11, The humidity-sensing layer 12 may be formed as shown. Alternatively, as shown in FIG. 3, it is also possible to form a groove by performing a depressed portion on a part of the surface of the substrate layer 11, and to fix the humidity-sensing layer 12 formed by pellet in the groove by interpolation The present invention is not limited thereto, and it will be understood by those skilled in the art that any method of forming the humidity-sensitive layer 12 on the base layer 11 is possible. As described above, the humidity-sensing layer 12 formed of pellets can be detachably fixed to the groove formed in the base layer 11. For example, in the case of printing, a composition containing a humidity-sensitive substance is printed on the base layer 11 by printing, particularly known gravure printing, flexographic printing, offset printing, screen printing or the like, 12 may be formed.

The porous, substrate base layer 11 may be formed of any one of diatomaceous earth, clay, loess, clay, alopen, peat, silicon dioxide, calcium oxide, calcium hydroxide, calcium carbonate, char, activated carbon, bentonite, vermiculite, sepiolite, Pozzolan, microcement, and the like into a plate shape. The above-mentioned separately-formed materials can be formed into a plate shape using a conventional method depending on the characteristics of each material. For example, diatomaceous earth, clay, loess, clay or alopen can be molded into a plate by adding water, followed by heating and firing to form a tile, as will be understood by those skilled in the art. In the above, allopen is a main component constituting natural minerals clay of volcanic ash, which is composed of porous fine particles, and is sold under the trade name "ECOCARAT" in Japan. Ecokarat is known to have the advantage of excellent abatement of formaldehyde, which is the cause of sick house syndrome. After 24 hours after construction, the concentration dropped rapidly, and the reduction effect continued even after that. It was the first building in Japan to be certified as a building material that reduces volatile organic compound pollution in indoor air from Japan Building Center. Ecokarat is a porous fine particle made of volcanic ash, which has excellent humidity control function, and is known to have absorption capacity of about 4 times to 5 times of diatomaceous earth and 15 times of humidity wall paper. Ecokarat absorbs moisture to lower the humidity when the humidity of the room is high, and releases moisture when the humidity is low. Therefore, it is possible to maintain the optimum humidity (50% to 60%) of the living space, to prevent the allergy and the atopic disease by suppressing the propagation of the germs. On the other hand, according to the results of experiments conducted by Japanese research institutes, ECOCARAT has an effect on alkaline odors such as ammonia and trimethylamine which are main components of odor, and acid odor components such as hydrogen sulfide and methylmercaptan. The odor removal and mitigation effects have been proven to be superior to the diatomaceous earth walls and other products. And the like are mixed with an organic binder or an inorganic binder and then molded into a tile to be mixed with an organic binder or an inorganic binder. Can be readily understood by those skilled in the art. In addition, the microcement constitutes a hard concrete by mixing with water due to its hydration, and can be formed into a tile shape by hydration. Micro cement is a particulate cement which is developed to be suitable for inorganic ground fillers and various repair or reinforcement materials. It is widely used as ground filler and repair reinforcing material, which require uniform grain size as well as roughness, high strength and high durability, . Micro cement is characterized by its excellent early strength (because it is a fine powder and has a rapid advance of activation and excellent early strength), it is capable of high strength expression (it has excellent strength development rate because it forms a compact matrix) And exhibits high permeability due to its small maximum particle size), and exhibits excellent durability (excellent chemical resistance against harmful substances such as salts and acids).

The humidity-sensitive material forming the humidity-perceptible layer 12 is well-known, and a substance selected from materials capable of absorbing and discoloring moisture in the air such as a cobalt compound, an iron compound, or a compound bonded to an alkali metal or an alkaline earth metal can be used .

Examples of the cobalt compound include cobalt chloride and organic dyes such as neural red, phenol red, bromothymol blue, phenolphthalein, cresol red, thymol blue, bromocresol green, bromocresol purple, bromocresol Blue or methyl red, or a mixture of two or more thereof.

The resin layer 21 may be further laminated between the moisture-sensing layer 12 and the base layer 11, as shown in Fig. The resin layer may be formed of at least one resin selected from epoxy resin, acrylic resin, polyethylene, polyurethane, phenol resin, melamine resin or polyvinyl chloride resin.

As shown in FIG. 5, a balance layer 31 may be further stacked on the back surface of the base layer 11. FIG. The balance layer 31 is formed of a plate-shaped product or a hard board made of a known plywood, an inorganic board, or a synthetic resin, and functions to facilitate a construction work such as a tacky work. The lamination of the balance layer 31 and the tacker work using the same can be easily understood by those skilled in the art. Takara work means to fix a stapler-like iron core to an object to be fixed by using manual, electric, hydraulic or pneumatic.

As shown in Fig. 6, a surface protective layer 41 having moisture permeability may be further laminated on the surface of the humidity-sensing layer 12. [ The surface protection layer 41 prevents the material constituting the humidity-sensing layer 12 located below it from directly entering into the eyes, nose or mouth by contact with the human body or through the hand, 12 is prevented from being worn or contaminated while moisture is allowed to pass therethrough so that the humidity-sensitive substance contained in the humidity-sensing layer 12 is discolored corresponding to the moisture. The surface protection layer 41 may be formed by coating a known air permeable film. The moisture-permeable surface protective layer 41 can be fixed by a method of thermally fusing a film having a thickness within a range of 0.01 to 0.15 mu m.

As shown in FIGS. 1 and 9, a pattern printing portion 13 may be further formed on the surface of the humidity-sensing layer 12. The pattern printing portion 13 is formed by applying an opaque paint or the like and the degree of discoloration of the humidity perception layer 12 can be directly compared with the color constituting the pattern of the pattern printing portion 13 by the naked eye So that the degree of discoloration can be recognized more easily.

7, the humidity control panel according to the present invention is characterized in that a plurality of humidity control tiles 10 having a humidity and humidity control function are fixed to a panel substrate 51 on which a plurality of tile fixing grooves 52 are formed . It consists of several small tiles in a single panel to facilitate handling, storage and installation work. That is, instead of fixedly fixing a plurality of small tiles in the field, a single large toughening panel 50, in which a plurality of tiles 10 are fixed to the tile fixing grooves 52 formed on the panel substrate 51 in advance, So that it is possible to obtain the same operation effect as when a large amount of tactile sense tiles are fixed at one time.
