Description

Antistatic tile using antimicrobial composition and construction method using the tile {ANTI-STATIC TILE USING THE ANTIMICROBIAL COMPOSITION, AND THE METHOD OF CONSTRUCTTION USING THE TILE}

The present invention relates to a conductive tile having an antimicrobial activity using an antimicrobial composition and a construction method using the tile.

More specifically, tiles that can obtain antimicrobial and antistatic effects at the same time by using an antimicrobial composition that is harmless to the human body and can have a long lasting antimicrobial performance, and a tile which allows the entire floor layer to be constructed using such a tile to last long. It is about a construction method.

Currently, tiles are widely used not only in homes such as kitchens and living room floors, but also in laboratories, hospitals, and the like, and bacteria and molds are odorous and unsanitary.

In particular, hundreds of harmful substances are generated in the spaces where we live, such as apartments, made of cement. Moreover, harmful materials such as formaldehyde, radon gas, and volatile organic compounds (VOCs) are generated from the paper and building finishing materials used in these residential spaces. Since these harmful substances cause serious harm to the health of residents, active research is being conducted on environmentally friendly building materials that do not emit harmful substances. Of course, the above problems are becoming a problem not only in apartments but also in laboratories and hospitals.

By the way, the antimicrobial treatment of the tile is introduced in the way that the silver is contained in the tile emulsion has been introduced, which is expensive and not popularized, there was a problem that the economic feasibility of such building tile antimicrobial.

In addition, a method of coating the surface of the antimicrobial agent is used, but most of the antimicrobial tiles treated in this way were those having a problem that the antimicrobial activity did not last long.

In addition, Published Utility Model No. 1999-15373 (May 15, 1999), `` Floor material with a microcapsule '', has a flooring material such as a floor covering made of a plurality of resin layers, tiles, and the like, wherein at least one of the resin layers has its interior. It is characterized in that the microcapsules having a size of 1 ~ 50㎛ containing the additive material in the interior, the antimicrobial agent was used as the additive material filled in the microcapsule, the antimicrobial agent is zeolite, zirconium phosphate, phosphoric acid An inorganic antimicrobial agent or an organic antimicrobial agent in which silver ions are bonded to a base material such as calcium, aluminum phosphate, silica gel, silica alumina, and amino acids is characterized by the above-mentioned. However, the microencapsulation of such antimicrobial agents takes a lot of manufacturing cost and time, and thus there is a problem that the tile construction itself is not easy and the antimicrobial performance does not last long.

In addition to the prior art, Korean Patent No. 678746 (2007.01.29) "Elastic flooring and its manufacturing method and construction method of elastic flooring using the same", Korean Utility Model No. 2000-4580 (2000.03.06) "Floor using charcoal Although the flooring material which shows the effect of the high efficiency far-infrared radiation, deodorization, and antimicrobial effect which a charcoal has, it also discloses the effect which is simply predictable from the existing natural ingredients, etc. to the flooring material as it is. But also had a problem that the antimicrobial activity does not last long.

In addition, even if there is a tile having such an antimicrobial activity, no functional tile capable of preventing static electricity or electromagnetic waves, which is a problem in the recent cutting-edge era, has not been introduced. In other words, due to the radical development of various electric and electronic technologies, industry and life are becoming highly integrated, highly intelligent, and cutting-edge with computers, and various kinds of electronic products, real life, and electromagnetic waves and static electricity that no one can expect in each field are generated. It is the current situation that is being damaged a lot by this. In particular, the damage caused by static electricity is so severe that damage to integrated circuits in semiconductor manufacturing lines, loss of data due to computer malfunctions, ignition / explosion of inflammables such as explosives, hospital infections in hospitals and post-operative infections, etc. Has been found to be damaged by static electricity. Therefore, in order to reduce the damage caused by the static electricity, various kinds of technologies for preventing static electricity have been developed, and up to now, the situation has been developed for preventing static electricity, tiles, flooring materials, mats, and the like.

However, the conductive mat or anti-static flooring material / tile for preventing static electricity is formed by applying a conductive material to the surface after forming the mat or by adding conductive materials such as carbon and surfactant to a synthetic resin material before manufacturing the mat. In addition, the tiles manufactured by adding the conductive material as described above have a problem in that the appearance is not beautiful due to the black color of the carbon as well as the antistatic performance deteriorates. In addition, when used for a long time, the surfactant rises on the surface of the mat, which is easily burned by dirt or added carbon.

In addition, as mentioned above, conventional antistatic tiles are not tiles with antimicrobial activity, even if the tile with antimicrobial power, there was a problem that the antimicrobial time does not last long and the performance falls.

This problem is particularly problematic in operating rooms of hospitals that require more antistatic and antimicrobial activity.

In order to solve the problems described above, the present invention provides a tile having antimicrobial power and antistatic performance by allowing an antimicrobial composition that is harmless to the human body and having excellent antimicrobial performance to be used as a transparent layer component provided on a tile having excellent antistatic efficiency. In addition, it is also an object of the present invention to provide a construction method that can ensure the maximum performance of the tile in the final construction space in the construction of such a tile.

That is, while solving the problem of complicated structure and increasing the manufacturing cost while adding charcoal, minerals, etc. in the conventional tile, while maintaining the characteristics of the general tile as it is excellent anti-static effect and antibacterial performance, and the tile, An object of the present invention is to provide a method of constructing a tile.

Generally used synthetic resin tiles are composed of a transparent film 40 of the uppermost layer, a color printing layer 20 below the transparent film, and a tile body 10 below the color printing layer. This is a non-conductive synthetic resin material exhibiting more than 10 14 Ω / ㎠, the synthetic resin tile of such a general structure is capable of forming a surface layer with a high hardness, it is excellent in commerciality because it can print a variety of colors or shapes on the color printing layer. However, there is a disadvantage that there is no antistatic ability, and furthermore, there is a disadvantage that the antimicrobial performance ultimately solved in the present invention was also not provided.

Referring to FIG. 1, the antistatic tile according to the present invention includes a topmost transparent film 40, a color printing film 20 provided under the transparent film 40, and a tile provided below the color printing film 20. It may be composed of a main body 10 and a conductive layer 60 provided below the tile main body 10. In FIG. 1, the conductive layer 60 is shown below the tile body 10, but the conductive layer 60 may be provided on the upper or lower portions of the tile body.

More preferably, the reinforcement film 30 may be further provided between the transparent film 40 and the color printing film 20 to ensure the strength of the tile.

Furthermore, the top of the transparent film 40, which is the uppermost layer, it is preferable that the UV coating layer 50 can be further provided to prevent ultraviolet rays and the like.

At this time, the combined thickness of the transparent film 40 and the reinforcing film 30 is preferably about 0.3mm, the thickness of the transparent film 40 is about 0.1mm, the thickness of the reinforcing film 30 is 0.2mm Do it inside or outside. More specifically, the thickness of the UV coating layer 50 and the transparent film 40 is 0.1mm, the thickness of the reinforcing film 30 is 0.2mm, the thickness of the color printing film 20 and the conductive layer 60 is 0.1 It is preferable to set it as mm, and to make the thickness of the tile main body 10 be 2.4 mm, and to make total thickness into about 3 mm. Each of these layers is integrally formed by thermocompression bonding with a heat roller.

The conductive layer 60 is preferably a carbon film, a carbon coated film, or a conductive film formed by thermo-compression molding containing carbon. Particularly, the carbon coated film is coated with carbon on one or both surfaces of the synthetic resin film 65. The carbon coatings 61 and 62 are formed by printing, and the carbon coating is formed on both surfaces of the synthetic resin film. In this way, the electrostatic effect is not only uniform, but it is also possible to manufacture an antistatic tile using carbon in a simple process and at a low price.

Of course, the conductive layer 60 is formed of a conductive film or carbon film which contains carbon in a synthetic resin material, and is then integrally formed by thermal compression with the tile body by a heat roller.

At least one of the tile body 10 or the color printing film 20 may further contain a surfactant. This is particularly preferable for tiles used in places where static electricity is generated frequently or when the amount of static electricity is generated is high.

That is, the transparent film 40 is formed of an antimicrobial composition containing a plasticizer and an antimicrobial agent in the PVC powder, the antimicrobial agent is preferably an inorganic antimicrobial agent using silver ions.

Therefore, the inorganic antimicrobial agent can be used without limitation inorganic antimicrobial agents such as silver (Ag), copper (Cu), zinc (Zn) series commonly used for the purpose of imparting antimicrobial properties to the resin composition containing the PVC powder and the plasticizer. More specifically, it is preferable to use a silver-based antimicrobial agent such as a form in which a negative metal (Ag), nano powder or silver (Ag) ions are supported on aluminum oxide (Al 2 O 3 ). In the case of using a form supported on aluminum oxide as a silver-based antimicrobial agent, an average particle diameter of aluminum oxide may be used in a range of 1 to 10 μm, preferably 2 to 7 μm. In view of the side is preferably about 3% by weight of the combined weight of the PVC powder and the plasticizer.

That is, the inorganic antimicrobial agent is preferably 3% by weight based on the weight of the PVC powder and the plasticizer. If the content is less than 3% by weight, the desired level of antimicrobial property cannot be given to the flooring material. It is not preferable because the appearance of the flooring material is poor and there is a problem that the production cost rises.

In addition, the resin composition is preferably made of 30 to 50% by weight of a plasticizer to 100 weight of the PVC powder.

Furthermore, it is preferable that the antistatic means is contained in the antimicrobial composition together with the antimicrobial agent, and the antistatic means is preferably contained at 30% by weight based on the weight of the PVC powder and the plasticizer. In particular, the antistatic means is preferably a conductive polymer.

In addition to the above components, the antimicrobial composition may be added in various amounts within a range capable of achieving the object of the present invention in a predetermined amount in addition to the rubber components, inorganic fillers, pillars, stabilizers and the like.

In particular, the silver ions used as the antimicrobial agent in the present invention is a natural material without toxicity. Accordingly, by forming the transparent layer of the tile according to the present invention as the antimicrobial composition, it is possible to provide an antimicrobial tile that is harmless to the human body and has an antimicrobial activity for a long time, and also has an antistatic effect.

In constructing the tile having the above configuration on the floor, even if the tiles having antimicrobial and antistatic effects are arranged on the floor, a space is formed between the surfaces of the tiles, and contaminants are introduced through the space. .

Therefore, in the present invention, it is preferable to go through the step of filling the gap between the tiles by applying wax to the upper surface of the tile in order to solve the above problems.

Of course, the wax painted on the tile surface is preferably formed of the antimicrobial composition discussed above.

Alternatively, the gap formed between the arranged tiles may be filled using an antibacterial electrode. In other words, by using a hot air welding machine is to be formed integrally with the tile while filling the gap between the tiles with an antimicrobial electrode treated with antibacterial treatment. Afterwards, the surface height of the contact portion of the antimicrobial electrode sticks to protrude more than the other tile surface height, which is arranged to cut the protruding surface so as to match the other tile surface.

As a result of measuring the surface resistance of the tile according to the present invention, it was confirmed that the surface electrical resistance of the tile falls below 10 13 Ω / ㎠ by the tunneling effect, and in practice the surface electrical resistance was 10 13 Ω / ㎠ It is known to exhibit sufficient antistatic effect below. For reference, the anti-static grade on the American mill spec (military spec) is more than 10 9 ㎠ / ㎠ and less than 10 14 Ω / ㎠.
