The present invention relates to a building flooring, and in particular, flooring applied to the floor of commercial and residential buildings, the surface layer is made of jade and the lower part of the water vein blocking, far-infrared emission, antibacterial, deodorization, cement poisoning, electromagnetic wave blocking or The present invention relates to a building flooring material in which a layer containing a material for exerting functions such as interlayer noise prevention is attached and integrated.

Jade is a substance containing K ₂ O, CaO, MgO, Fe ₂ O ₃ , SO ₃ , Al ₂ O ₃ , SiO ₂ , Al ₂ O ₃ , Na ₂ O, MnO, TiO _2, etc. Not only is it very beneficial, it is called a health jewel to chase bad luck and bring good luck. Sleeping with jade gives you a good night's sleep and is good for your heart. In particular, jade records are recorded in ancient books such as herbal trees, which remove heat in the stomach, smooth heart activity and lung capacity, stabilize the mind, brighten eyes and ears, and improve blood circulation. It has the effect of lowering the temperature. In addition, it has been found that it has good thermal conductivity and excellent heat resistance, so that it can be maintained at an appropriate temperature even when applied to ondol. Moreover, jade has high far-infrared emissivity and functions like ocher and germanium, and it is confirmed that anion emission efficiency is higher than ocher, elvan, ceramic and germanium.

Until now, jade has been used mainly for various kinds of ornaments, ceramics, decorative items, etc. Today, as the efficacy of the above-mentioned jade is known, it is gradually applied to the parts necessary for residential life such as jjimjilbang and jade mat.

On the other hand, with respect to the flooring imparted functionality, a method of blocking water waves by coating a synthetic resin on both sides of the aluminum or copper main body (Korean Patent Publication No. 1998-0025790), copper, nickel, ceramics in the lower layer in the multi-layered flooring Method of blocking water wave by adding powder etc. (Korean Utility Model Model No. 1998-0055609), Method of applying after pasting jade powder on synthetic resin such as PVC (Korean Patent No. 448099), Aluminum powder and conductive carbon powder As the resin to which is added, many are known, such as water vein blocking resin (Korea Patent Publication No. 2003-0038215).

However, the above methods show some effects on the desired performance, but most of them are used as coatings or adhesives by adding powders expressing functionalities to synthetic resins.

In the case of the prior art, because the synthetic resin is used, when the flooring is applied, toxic substances or environmental hormones, which are harmful to the human body, are released, and thus, the environmentally friendly products cannot be referred to. There is also room for improvement in each function.

On the other hand, if jade is applied to the floor of a building, especially an apartment, such as an apartment, it is obvious that it may help to maintain the health of the human body due to the effect of the above-described jade, but jade is brittle, impact on the floor It has the disadvantage of being vulnerable.

In addition, the adhesive used to attach the jade to the floor, as described above, contains a lot of harmful components to the human body, because in Korea, ondol structure is widely used on the floor of buildings, especially residential buildings, as the synthetic resin When using the prepared adhesive, there is a problem that a large amount of harmful substances can be released from the floor due to the high temperature of the floor.

In addition, the problem of floor noise is severe in a multi-family house such as an apartment, and the floor covering of the apartment needs to be provided with floor noise or dustproofness.

The present invention overcomes the disadvantages of the prior art described above, and at the same time to provide a building flooring material maximized functionality by the addition of water vein blocking, far-infrared emission, antibacterial, deodorization, cement poison removal, electromagnetic wave blocking and noise removal or dustproofing effect. It is a task.

In addition, the present invention is to solve the problems caused by applying the jade as a flooring material, and the flooring material is not damaged well in the external impact, to provide a flooring material that is very convenient during construction.

As a constitution for achieving the object of the present invention, firstly, the present invention is a jade layer constituting the upper surface of the flooring material and a first adhesive layer, silver (Ag) nano-layer, a second adhesive layer, And it provides a building flooring characterized in that the release film layer is arranged in sequence.

In the above-described configuration, the jade layer has a harmful wave blocking function such as far-infrared emission, water wave, and electromagnetic wave.

In addition, the first adhesive layer and the second adhesive layer disposed between the silver (Ag) nanolayers not only function to bond the silver (Ag) nanolayer and the jade layer, and the silver (Ag) nanolayer and the bottom. By absorbing the impact applied to the jade layer through the impact absorbing force of the adhesive, the brittle jade is prevented from being broken, and the interlayer noise is removed or dustproof.

The release film layer disposed at the bottom serves to remove handling inconvenience caused by the adhesive before the flooring material of the present invention is constructed.

The configuration of the present invention is to take advantage of jade by placing a layer of jade having a very beneficial effect on the human body and a silver (Ag) nano layer that is very effective in antibacterial and deodorizing and between them two layers of adhesive, Jade is to cover the shortcomings, even in the construction, if only remove the release film attached to the bottom of the flooring, it is very convenient because it can be installed immediately.

In addition, according to another aspect of the present invention, in the above-described building flooring, the far-infrared emission layer is replaced by adding or replacing the silver (Ag) nano layer between the adhesive layer and the silver (Ag) nano layer attached to one surface of the jade layer. It provides a building flooring comprising a.

As such, by including the far-infrared emitting layer, it is possible to emit sufficient far-infrared rays together with the far-infrared rays emitted from the jade. On the other hand, as the far infrared ray emitting material, one or more selected from the group consisting of illite, loess, elvan, and charcoal can be used. However, among the far-infrared emitters, illite generates a large amount of negative ions in itself and emits 93% of far-infrared rays, which are beneficial to the human body, and improves the sense of temperature above 5 ℃, removes toxins, and does not swell in water. It also sterilizes and sterilizes molds and removes the cement poison if the flooring is made of cement. Therefore, illite is most preferred as a far infrared ray emitting material. On the other hand, in consideration of affinity and dispersibility with the adhesive component, the elite powder is most preferably a 3000 mesh passage.

In addition, as will be described below, in the case where a far infrared ray emitting material and an adhesive are mixed and used, the illite is mixed within a range of 5 to 50% by weight based on the total mixture. If it is within 5% by weight, it is difficult to expect effects such as far-infrared emission and removal of cement poison. If it exceeds 50% by weight, it is not preferable because it lowers the physical properties of the adhesive.

According to yet another aspect of the present invention, an jade layer constituting the top surface of the flooring material and one surface of the jade layer are prepared by mixing an adhesive, silver (Ag) nano powder, and one or both of the far infrared ray emitting material. It provides a building flooring, characterized in that the mixed layer and the release film layer is arranged in sequence.

In this configuration, the adhesive, the silver (Ag) nanopowder and the far infrared ray emitting material are not divided into respective layers, but are mixed in advance and adhered to the lower part of the jade, thereby providing convenience of the process.

In addition, according to another aspect of the present invention, a mixture layer prepared by mixing an adhesive and a far-infrared ray emitting material, and a release film layer are sequentially arranged on the jade layer constituting the top surface of the flooring material and one surface of the jade layer, and the mixture layer It provides a building flooring, characterized in that additionally arranged in the interior of the silver nano-fiber layer.

As such, when the silver nanofiber layer is disposed between the mixture layers, the silver nano fiber layer serves as a support layer that can structurally support the mixture layer, as compared with the case where silver nano powder is mixed with an adhesive to produce a sheet. There is an advantage that can make the work of flooring very convenient. Silver nanofibers are usually produced and sold, and are not particularly limited, and silver nanofibers usually use a thickness of 0.05 to 1 mm.

According to another aspect of the present invention, the present invention is a flooring material which is constructed on the floor of a building, the flooring material includes an jade layer, an adhesive layer disposed on one surface of the jade layer, and a release film attached to the adhesive layer. The adhesive layer contains 40 to 90% by weight of polyisoprene and ₅ to 60% by weight of one or more from the group consisting of silica (SiO ₂ ), calcium carbonate (CaCO ₃ ), titania (TiO ₂ ), and carbon black. It contains% and the rest is made of inevitable impurities provide building flooring. The inevitable impurities refer to impurities which are inevitably introduced in the manufacturing process of the adhesive due to limitations of the manufacturing equipment.

When the content of polyisoprene is less than 40% by weight, the hardness and modulus of the adhesive layer are weak and the elongation is long, which acts as a factor that inhibits adhesion. It is not preferable because it becomes too high and the drawing is too low, which also inhibits adhesion. On the other hand, when the content of the filler, such as silica is less than 5% by weight, the adhesive force is lowered, on the contrary, when the content of the filler exceeds 60% by weight, the elasticity of the adhesive is reduced and the adhesion is also undesirably undesirable.

The polyisoprene used in the adhesive of the present invention functions as an adhesive and at the same time absorbs the impact from the upper surface portion, thereby ultimately removing the noise between layers or dustproofing. In addition, the adhesive does not contain lead or heavy metal materials and formaldehyde in particular, so there is little release of harmful components to the human body.

Meanwhile, as the reinforcing filler, the above-described calcium carbonate, silica, titania, carbon black, and the like may be used. Among them, silica is not only able to preserve the natural color of jade, but also corresponds to the main component of concrete, which is the interface between jade and the bottom, which is the upper boundary. It will also act to enhance the adhesion of the. Thus, silica is most preferred as a filler.

On the other hand, the thickness of an adhesive bond layer is about 0.5-30 mm, and it is preferable that it is 1-10 mm. If the thickness of the adhesive layer is less than 1 mm, sufficient adhesive strength cannot be expected, and furthermore, the adhesive layer also serves to correct the difference in the flatness of the bottom surface when applied to the floor. .

Hereinafter, the present invention will be described in more detail with reference to Examples. However, the following examples are merely illustrative and should not be construed as limiting the invention.
