Description

Flooring with electromagnetic and water wave blocking function

In the present invention, a conductive filler is added to the raw material of the flooring material to make the vinyl flooring material conductive, thereby blocking electromagnetic waves or having a grounding effect with the ground floor. The present invention relates to a flooring material which can be used and can block harmful water waves.

In general, PVC flooring material has excellent insulation property, so it has insulation effect, but it cannot block harmful electromagnetic waves and water waves.

Electromagnetic waves are electromagnetic energy with a wide frequency range occurring in the flow of electricity and magnetism. When vibrations occur in electricity, electric and magnetic forces are generated at the same time, and the waves generated by periodic changes are called electromagnetic waves. Electromagnetic waves are classified into ultra low frequency (0 to 1000 Hz) including power frequency 60 Hz, low frequency (1 to 500 KHz), communication frequency (500 KHz to 3000 MHz), and microwave (300 MHz to 300 GHz).

Recently, due to the use of electronic devices and human exposure of harmful electromagnetic waves generated from high-voltage transmission and distribution lines, social problems have arisen due to their harmfulness. Although the hazards from exposure to electromagnetic waves have not been clearly identified, the hazards have recently been revealed little by little and the emission limits of electromagnetic waves are legally regulated. Such electromagnetic waves may be blocked by conductors due to their characteristics. Normal electromagnetic waves are easily stopped and blocked when they come in contact with other charges in the conductor.

The electromagnetic shielding technology known so far in the field of flooring is known to have a function of partially shielding electromagnetic waves by radiation of far infrared rays in flooring using far-infrared radiation ceramics. However, the flooring material using far-infrared radiation ceramics mainly aims to emit far-infrared rays, which are beneficial to the human body, and the electromagnetic wave shielding function is additional, and thus, sufficient electromagnetic shielding function cannot be expected.

On the other hand, on the earth, there are surface stations like rivers and underground water flowing through the ground, and this groundwater is gradually moving in layers between layers of permeable soil or rocks. German physicist W.O Schumann first reported the creation of an electromagnetic field on Earth for the first time in 1952, saying it resembles the brainwaves of the human body. Earth's natural vibration frequency is 7.8 Hz, which is the harmless frequency of the earth. However, the water wave coming out of the interface between the water veins and the soil is not such a normal frequency, but a completely different type of unstable electromagnetic wave in which the unique vibration wave of the earth is disturbed by the water vein and the waveform is modulated and amplified. Therefore, if the natural vibration wave of the earth vibrates up and down by water vein when a person takes a good night's sleep, the brain wave of the person on it also resonates with him, so that it stays in the state of 7-8 Hz without falling below the deep sleep state of 4 Hz. Will be. It's as if the car is passing by next to the TV and the radio wave enters and the screen shakes. Therefore, if you do not prevent the water wave, our brain wave interferes with abnormal water wave and loses the high vitreous rhythm. This water wave not only affects the first floor of the building but also vertically affects the water wave up to 20 floors or more.

As a method of preventing such water wave, it is known to lay a copper plate on the floor. Water waves are also electromagnetic waves of abnormal waves, so when they touch a conductor, they can be easily cut off by turning into thermal energy. Therefore, if the copper plate is laid, most of the water waves will be blocked, which can reduce the damage of the water veins. However, due to the high price of the copper plate itself, there is a difficulty in commercialization, and it requires a cumbersome task of re-installing the flooring material after laying the copper plate separately during construction. As such, there is a flooring material in which a thin copper plate is attached to the flooring material itself without separately constructing the copper plate and the flooring material, but in the case of the flooring material to which the copper plate is attached, a separate copper plate must be attached to the flooring material after manufacturing the flooring material. And, there is a problem in that the construction of the flooring is inconvenient compared to the conventional flooring. In addition, the pure copper plate is oxidized in contact with air and moisture, and as the oxidation proceeds, the electromagnetic and water wave blocking effect is reduced.

As described above, the conventional flooring manufacturing technology and construction technology were applied as it is, the situation for the electromagnetic wave and water wave blocking flooring material showing a continuous effect has not been developed.

Accordingly, an object of the present invention is to provide an electromagnetic wave and water-wave blocking flooring material by applying a conventional flooring manufacturing technology and construction technology as it is, making the manufacturing process and the construction work easier and greatly improving workability.

The present inventors earnestly researched to develop a flooring material that can achieve the above object, and by adding a conductive filler to the blending material of the flooring material, the flooring material becomes conductive, absorbs electromagnetic waves and water waves, and improves the grounding effect through the floor surface. The present invention was completed by revealing that the electromagnetic wave and the water wave can be effectively and continuously blocked, and also the manufacturing process and construction trouble can be eliminated.

Conductive fillers used in the present invention include plate-like copper powder (Cu powder) and magnetite-containing ceramic powder, etc., the double magnetite-containing ceramic powder generates a magnetic field to form a weak magnetic film to prevent harmful waves pass through the water vein blocking effect It can be maximized. In addition, plate-like copper powder has a semi-permanent electromagnetic and water wave shielding performance because it is treated with an anti-oxidation treatment by coating nickel or silver to compensate for the disadvantage of being oxidized. "Magnetite-containing ceramic powder" can use "Everfree" (manufactured by Human Tech Co., Ltd.) and MD150 (manufactured by M.D.

In the flooring of the present invention, the content of the conductive filler blended into the lower layer and the back layer is preferably 10 to 50 parts by weight for each layer. Therefore, the total amount of the conductive filler blended to the flooring material is suitable 20 to 100 parts by weight, less than 20 parts by weight of the electromagnetic wave and water wave blocking effect is insignificant, if the content of more than 100 parts by weight of the filler itself is a solid powder, the viscosity of the PVC resin increases Therefore, it is not preferable.

Hereinafter, the effects of the present invention will be described in detail through application examples.

Application example 1

In the flooring having the structure as shown in FIG. 1, magnetite-containing ceramic powder (MD150, manufactured by MD BOTH Co., Ltd.) was added to the lower layer 6, and the flooring was manufactured by the conventional method described above. Surface resistance values were measured using a surface resistance meter (Megaresta (HT-301), manufactured by Shishido Electric Co., Ltd., Japan). The meaning of the surface resistance value is a good conductor when the electromagnetic wave or the water wave touches the conductor and is consumed by thermal energy, etc., and thus the smaller the resistance value, the better the electromagnetic and water wave blocking ability.

Surface resistance measurement results are shown in Table 1.

Table 1.

Application example 2

In the flooring having the structure as shown in FIG. 1, plate-like copper powder was added to the back layer 8 as a conductive filler to prepare a flooring, and the surface resistance value was measured as in Application Example 1.

The results are shown in Table 2.

Table 2.

Application example 3

In the flooring having the structure as shown in FIG. 1, the flooring was prepared by applying magnetite-containing ceramic powder to the lower layer 6 and plate-like copper powder to the backing layer 8, and the surface resistance value was measured as in Application Example 1.

The results are shown in Table 3.

Table 3.

The flooring according to the present invention can be easily manufactured in accordance with the conventional flooring manufacturing process, unlike the conventional copper plate to prevent the electromagnetic or water wave can be avoided in the manufacturing process hassle and construction hassle It has great advantages in terms of ease of use, and it is effective because it can continuously maintain the electromagnetic and water wave blocking effects after construction. The flooring manufactured according to the present invention blocks electromagnetic waves and water waves by forming plate-like copper powder on the back surface of the flooring material, and forms a copper plate, and the blocking principle is that electromagnetic and water-wave waves that touch the plate-like powder of the back layer 8 pass. It can't be released and changes to eddy current or heat energy along with copper powder with good electrical conductivity.

Copper is a non-magnetic metal with excellent electrical conductivity, and is very effective in blocking low frequencies such as electromagnetic waves and water waves.

In addition, a magnetite-containing ceramic powder was used in the lower layer 6 to form a magnetic field on the bottom surface, thereby blocking the electromagnetic wave and the water wave twice, thereby maximizing the blocking effect of the electromagnetic wave and the water wave. The magnetite-containing ceramic powder used in this case has an effect of blocking electromagnetic waves and water waves by dispersing and breaking the energy wavewalls so that the water waves cannot pass through the energy field by transmitting and forming an energy field on the surface of a surface or concrete of a building.

In addition, the copper plate has a decrease in effect due to natural oxidation over time, but the plate-like copper powder used in the present invention has an anti-oxidation treatment and has a semi-permanent electromagnetic and water wave blocking effect after construction.

It is also possible to apply plate-like copper powder or magnetite-containing ceramic powder to other layers other than the back layer and the lower layer.
