The present invention relates to a flooring comprising a functional film containing a PVC film having a blood circulation characteristic and water vein blocking effect as the upper layer. More specifically, the present invention provides a superior blood circulation and water-blocking effect by constructing the uppermost layer of a PVC film containing pegmatite (crystallized stone) pulverized-containing functional powder aged by Bacullus species SSA3. It relates to the flooring given.

Pegmatite is a differentiated deposit product of magma, also called coarse granite, and colored ore and pharmacological ore are particularly called macrophage pegmatite. The pegmatite is a mineral containing nine components that are beneficial to the human body among a single twenty components. As a result, pegmatite exhibits effects such as far-infrared radiation, antibacterial deodorization, water-wave, and electromagnetic wave blocking. In particular, the ability to radiate far-infrared radiation can exert functions such as cell activation and blood circulation in the body. For example, Korean Patent No. 366879 is used for human blood circulation by mixing pegmatite and a small amount of inorganic elements. Pegmatite-containing powders are disclosed.

In addition, techniques for producing functional products by preparing pegmatite in various forms are known. In this regard, Korean Patent No. 506691 discloses a method for producing a fabric having the effects of various harmful waves, far-infrared radiation, etc. by applying pegmatite powder. In addition, Korean Patent No. 426789 discloses a method of manufacturing functional fibers by coating a fiber with chitosan and pegmatite as a sanitary processing agent, and the fiber manufactured according to the patent has a moisturizing effect and far infrared rays with an antibacterial deodorizing effect. It has been evaluated that the effect can be improved.

In contrast, the applicant's Korean Patent Application No. 2006-2132 discloses a pegmatite powder having a specific particle size characteristic in order to maximize the beneficial properties of pegmatite (particularly, blood circulation, far-infrared radiation, antibacterial and deodorizing performance) of Bacillus strains ( A method of aging in the presence of Bacullus species SSA3) is applied to the processing of natural leather.

On the other hand, in recent years, attempts have been made to give beneficial functions to flooring that is closely related to the living environment. For example, Korean Patent Publication No. 2005-43823 discloses a flooring material that gives anion generating effect of tourmaline and feldspar, and Korean Patent Application No. 1998-55520 discloses a bottom layer, an intermediate layer, and an upper layer layer from the bottom. As a laminated material sequentially laminated to the top of the upper layer has been disclosed a technique for achieving the effect of removing odor, far-infrared radiation and the like on the flooring by laminating a UV coating layer microcapsules microcapsules.

In addition, Utility Model Publication No. 2000-4580 discloses a flooring material that exhibits high efficiency of far-infrared radiation and deodorization as well as floor finishing function by containing charcoal in any one or two or more layers of the flooring material. have.

However, the above-mentioned technique merely attempts to give the flooring material the effect of a predictable degree from the existing natural mineral powder component or the like as it is. In particular, as described above, considering that technologies for facilitating blood circulation of the human body are recently developed by shielding electromagnetic waves or water veins that are frequently exposed from the surroundings, they provide better functionality in the field of flooring that is close to the living environment. The need is raised.

Accordingly, the present inventors have conducted extensive research to overcome the limitations of the prior art, and have incorporated certain functional powders, which have been found to exhibit excellent performance in electromagnetic and water wave shielding, far-infrared radiation, antibacterial and deodorizing effects, to PVC films. By applying the film thus prepared as the upper layer of the flooring material, blood circulation function can be achieved through far-infrared radiation, antibacterial deodorization, and electromagnetic and water-wave shielding, which are far beyond the effect recognized from pegmatite. Was found.

Accordingly, an object of the present invention is to provide a flooring material that is provided with a PVC film incorporating powder having improved blood circulation characteristics through excellent far-infrared radiation and antibacterial deodorizing performance and harmful wave shielding.

In order to achieve the above object, the present invention is a multi-layered flooring comprising a base layer, an intermediate layer, and the upper layer, i) 100 parts by weight of PVC resin, ii) aged by Bacillus species (SAcillus strain SSA3) and 0.35 A PVC film layer comprising 1 to 10 parts by weight of pegmatite finely ground powder having a particle size of ˜1 μm and i) 20 to 36 parts by weight of a plasticizer and 1 to 4 parts by weight of a stabilizer is formed as an upper layer. The thickness of the PVC film is characterized in that 0.2 to 0.5mm.

Hereinafter, the present invention can be achieved by the following description with reference to the accompanying drawings.

1 is a process diagram schematically showing the manufacturing process of the PVC film for forming the upper layer of the flooring material in the present invention.

In the present invention, the component which is incorporated into the PVC film useful as the upper layer of the flooring material to impart far-infrared radiation, antibacterial deodorization, and blood circulation function is described in the Korean Patent Application No. 2006-2132 by the applicant of the present invention as described above. As a functional powder applied to leather products, the prior art is included as a reference of the present invention. The manufacturing method of the functional powder is briefly described as follows.

First, a process of crushing or coarsely crushing pegmatite ore is performed. For this process, preferably, a crusher known in the art can be used without particular limitation, for example a jaw crusher can be used. The crushed pegmatite is then further ground to the appropriate particle size, preferably using an impact crusher to achieve about 300-400 mesh.

As described above, the pulverized pegmatite is subjected to a fine grinding process to have a finer and more uniform particle size, and an air jet mill is an exemplary apparatus used for this purpose. In the case of the pulverization process, by using a compressor air of typically about 5 to 10 kg / cm 2, preferably about 6 to 8 kg / cm 2, minerals that may occur due to incorporation of foreign matters and friction in the grinding process, etc. Component changes can be suppressed. The fine pulverized product obtained as a result of the fine pulverization process has a particle size of about 0.35 ~ 1㎛, if it is less than the particle size level, for example, it is separated through the screening process using a two-stage fine pulverized again Recycled in the process, it is preferable that the pulverized powder has a spherical shape.

The pegmatite pulverized powder obtained as described above can be mixed with trace amounts of auxiliary metal components, thereby adding content of various effective metal components contained in pegmatite to prevent far-infrared radiation, electromagnetic and water wave blocking, and antibacterial deodorization performance. It can be maximized. The auxiliary metal component is preferably used in the range of about 0.1% by weight, preferably within 0.05% by weight, based on the entire mixture, because the economical efficiency is lowered compared to the effect of adding an excessively large amount. to be. Examples of such an auxiliary metal component include Ca, Ge, Se, Ho, Ce, Zr, La, Y, and the like, and one or two or more thereof may be selected and used. Air blenders may be used as a device suitable for mixing pegmatite fines and auxiliary inorganic metals, preferably high speed blending for about 20-40 minutes, typically about 30 minutes.

All the mixture powders prepared as described above are non-irritating to humans as they are natural ingredients, and specific compositions are shown in Table 1 below.

element Content (% by weight) SiO ₂ 65.52 Al ₂ O ₃ 22.81 Fe ₂ O ₃ 3.20 CaO 1.69 MgO 1.40 Na ₂ O 1.92 TiO ₂ 0.79 K ₂ O 2.16 Ge 0.014 Se 0.032 Zr 0.0113 Ca 0.045 Ho <0.0001 Y 0.0015 La 0.0076 Ce 0.011 Etc 0.3875

The pegmatite-containing powder prepared as above is aged in the presence of Bacillus species SSA3. These Bacillus strains are typically isolated from aged soy sauce soaked in conventional methods in the home, in this design a strain deposited with accession number KCTC 8488 (May 23, 1990) was used. The Bacillus strain exhibits the characteristics that can be produced in a single bacteria fermentation, conventionally has been applied to medicines or food by separating the pigment from it. For example, Korean Patent No. 371387 discloses a method for purifying antimutagenic pigments by separating the dye produced by Bacillus species SSA3 in the order of centrifugation-cationic column chromatography-elution-decompression-concentration-drying. have.

At this time, the aging process is carried out for about 10 to 20 days, preferably about 14 to 16 days at a temperature condition of about 35 ~ 45 ℃, preferably about 38 ~ 42 ℃, and also the traditional Onggi to allow air in and out It is desirable to maintain an environment similar to the space within. After the above aging process is completed, the drying process to facilitate storage, etc., it is preferable to dry in a natural state rather than artificial manipulation, but in the dark-cooled environment (dark and cool environment) it is preferable to make the water less than 0.5%. . In some cases, the dried powder may be aged again and dried.

In the present invention, the flooring upper layer film basically has a composition of the ratio of about 1 to 10 parts by weight of the above-mentioned functional powder, 20 to 36 parts by weight of plasticizer and 1 to 4 parts by weight of stabilizer, relative to 100 parts by weight of PVC resin.

At this time, the PVC resin used as the main component preferably has a degree of polymerization of about 1000 to 3000, more preferably about 1200 to 2500, and most preferably about 1300 to 2000 so as to be suitable for application to the upper layer of the flooring material.

On the other hand, the plasticizer (plasticizer) is used to control the strength of the film and can be used in the art well known in the art, for example, dioctyl phthalate (DOP), diisononyl phthalate (Diisononyl Phthalate), Butyl benzyl phthalate may be used, and more preferably dioctyl phthalate (DOP) is used. As for the usage-amount of the said plasticizer, about 3-7 weight part is more preferable. If the amount of plasticizer used is too small, it is difficult to proceed smoothly due to the lack of softening properties in the film manufacturing process, but when used in excessive amounts, the mechanical properties of the film may be reduced, so it is preferable to control the above range. Do.

In addition, stabilizers are ingredients added to prevent the mattress resin, PVC, from working on devices such as rolls during processing and worsening workability. Typically, barium-zinc-based, tin-based stabilizers (e.g., dibutyl Tin maleate), preferably about 2 to 3 parts by weight. In addition, auxiliary components, such as a viscosity reducing agent, an ultraviolet stabilizer, and a filler, can be selectively used within the range of about 0.1 to 5 parts by weight. If it is used in an excessively small amount, the above-described addition effect cannot be obtained, but if it is used in an excessively large amount, it may need to be appropriately adjusted since it may adversely affect workability.

An exemplary manufacturing method of the film for the upper layer may be described as follows, but the present invention is not necessarily limited thereto.

First, the PVC resin, the plasticizer, and the stabilizer are added together in a blender to perform a compounding process, so that the particles of each raw material component are loosened to be uniformly blended. Mix for 3-10 minutes. Then, the above-mentioned functional powder is added in an amount in the above-described range, and then blended again, wherein the blending time is suitably about 3 to 10 minutes.

As described above, when the compounding process is completed, a rolling process is performed, and the rolling process is processed into a sheet shape to be suitable for performing not only mixing (kneading) of raw material components, but also a subsequent calendering process. It is a process. In other words, it is a process of processing the blended powdery ingredients under heating using a roller. According to a preferred aspect of the present invention, divided into three steps of rolling process, the first rolling → second rolling → third rolling is carried out while increasing the temperature because the raw material components are mixed or kneaded in a uniform composition This is because subsequent calendaring operations can be easily performed. In particular, the above-described multistage rolling is preferable in view of enabling smooth kneading between the powder and the other components of the component giving the main function in the present invention.

  Specifically, the first rolling process is performed at a temperature of, for example, about 200 to 210 ° C. so that the powder of the blended raw material is converted into a gel state. In the case of the secondary rolling process, the raw material in a gel state is first molded into a sheet, and is performed at a higher temperature condition than that of the primary rolling, for example, at a temperature of about 220 to 230 ° C. Next, the third rolling process is a process of secondary molding in the form of a sheet so that it can be easily applied to a subsequent calendering process, for example, it is performed at about 250 to 270 ° C. If it is out of the above-mentioned temperature range, it may cause difficulty in kneading with other components due to the PVC resin properties, which may cause problems in terms of uniformity of physical properties, and may cause rough surfaces or in connection with subsequent calendering processes. May adversely affect Therefore, it is desirable to maintain the above temperature conditions. In addition, the pressure applied during each rolling can be appropriately adjusted within the range of about 5-20 kg / cm 2.

When the above-described rolling process is completed, the upper layer of the flooring material is formed into a film having a standard (thickness, width, etc.) suitable for the application through a calendering process well known in the art, and is processed in a roll state. In particular, in the case of the flooring (particularly, tile decoration) to be provided in the present invention, a thickness of about 0.2 to 0.5 mm is appropriate, which takes into account the relationship with other layers constituting the conventional flooring. That is, the above-described thickness range is set so that the functional powder can be appropriately applied to the upper layer of the flooring in the form of being mixed in the film. In addition, the width of the film is determined depending on the use and the like, but is typically in the range of about 70 to 120 cm. The temperature during the calendering process is preferably set equal to the temperature during the third rolling and configured to maintain the temperature automatically, and the pressure is sufficient if the level is about 10-30 kg / cm 2. In addition, the discharge rate may be adjusted to allow for continuous production in consideration of the discharge rate during rolling, typically in the range of about 25-40 m / min.

Since the film that has undergone the calendering process is transferred to the freezer, it is preferable to rapidly freeze it in order to minimize the change in the shape of the film. At this time, the temperature of the refrigerator is preferably in the range of about 7 to 12 ° C. Next, it is cut to an appropriate size to meet the requirements of the flooring material and then applied in the flooring manufacturing process.

According to the present invention, the film produced through the above process is a wide range of upper layer without particular limitation in the manufacture of conventional flooring (for example, flooring typically including the base layer structure of the underlying layer-middle layer-upper layer). Can be applied as For example, a base layer, an intermediate layer, and an upper layer (PVC film) may be separately formed and laminated at a time by laminating under pressure, or the base layer and the intermediate layer are laminated in advance, and then the PVC film corresponding to the upper layer on the laminate. It may be laminated under pressure by supplying

2A and 2B are cross-sectional views schematically showing the structure of the flooring provided by the present invention. The drawings are provided for illustrative purposes only, and as long as the above-described film can be used as the upper layer, a configuration of flooring known in the art can be adopted without limitation. For example, except for the upper layer, it may have a laminate structure disclosed in Korean Utility Model Nos. 20-343899 and 20-211996, Korean Patent Nos. 295341 and 380041. The prior art is included as a reference of the present invention.

As described above, after the upper layer is formed, it is typical to apply UV-curing compositions known in the art to the upper layer to cure UV, which is to protect the upper layer from external physical or chemical stimuli.

As described above, the PVC film containing the functional powder prepared by aging the pegmatite-containing powder with Bacillus species SSA3 is not only excellent in far-infrared radiation, antibacterial function, etc. It has an excellent shielding effect in various electromagnetic waves, water waves, etc., and is applied to the upper layer of the flooring material, which has a favorable effect on the blood circulation of the human body.
