Anti-bacterial Wallpaper Comprising Far-Infared Light Radiation Material and Method of Making the Same}

The present invention relates to an antimicrobial wallpaper containing a far-infrared radiation material and a method for manufacturing the same. The present invention relates to an antimicrobial wallpaper containing a far-infrared radiation material which maximizes the effect of far-infrared radiation, and in particular, the deodorizing power and the antimicrobial activity, and a method of manufacturing the same.

As is well known, far-infrared rays are infrared rays having a wavelength band of 2.5 ~ 1000㎛ within the wavelength range of infrared rays, which is longer than visible rays and shorter than microwaves. It has the effect of prevention, deodorization, deodorization, antibacterial and antibacterial. In addition, the wavelength range of 5 ~ 15㎛ of far infrared rays is known to have the most beneficial effect on the human body, penetrate to the subcutaneous 40mm of the human body to cause vibration of atoms and molecules, thermal reactions in the body and to increase the temperature of the subcutaneous tissue Increasing capillaries, promoting blood circulation, enhancing metabolism, and reviving cell tissues have been reported to have effects such as warming, aging, and fatigue.

Accordingly, the application of far-infrared radiation is being proposed in almost all industrial fields. Especially, as the interest in health housing and consumer's desire for residential environment have increased recently, in the construction field, ocher, elvan, illite, zeolite, Far-infrared radiant natural materials such as mica, kaolin, jade, and charcoal have been used in various ways. Condensation phenomena occurring in concrete housings with good ventilation and relatively poor ventilation of the human body of heat-dried indoor air according to the change of residential heating system converted from conventional heating floor radiant heating to air convection, By applying the problems such as mold, flooring, wall, ceiling, wallpaper, brick, etc. using far-infrared radiation ceramics, it aims to promote drying effect, humidity control, insect repellent, antibacterial, deodorization, and warming effect.

Conventionally, in the application technology for the wallpaper of the far-infrared radiation material, natural minerals such as ocher, elvan, and illite are simply pulverized (for example, not subjected to chemical refining process) to maintain an appropriate particle size, binder, dispersant, starch, etc. Most of the techniques for mixing and laminating and coating them on wallpaper paper, and in some cases, a technique for applying the far-infrared fine powder ceramics to paper stock (water + pulp) and applying it to the wallpaper paper itself.

For example, Korean Patent Laid-Open Publication No. 1998-0002434 discloses far-infrared radiation in which water, a binder, ocher powder, illite powder, elvan rock powder, starch, antifoaming agent, dispersant, calcium bicarbonate, microcell, volcanic ash, and the like are mixed at a predetermined ratio. The technique of applying the material to the wallpaper base paper has been proposed, the Republic of Korea Patent Publication No. 1999-0039262 to obtain the humidity control, deodorizing function and far-infrared radiation effect by the ocher component by coating the resin mixed with the ocher on the surface of the wallpaper of the wallpaper The Korean Patent Publication No. 1997-0015927 discloses a far-infrared radiation substance mixed with water, binder, antifoaming agent, starch, dispersant, etc. in a predetermined ratio in Korean Patent Application Publication No. 1997-0015927. (Wallpaper base) Apply to a certain thickness on the surface and dry it, and then print the pattern on the upper layer, and topcoat any one of UV, urethane and moisture-permeable urethane. By proposing a method of manufacturing a radiation-containing material produced wallpaper.

In addition, the Republic of Korea Patent Publication No. 2000-0000268 intensifies and reduces the far-infrared radiation material such as ocher, illite, silica sand or kaolin to a predetermined temperature, and then finely powdered to a predetermined particle size, condensed water and the beaten pulp Mixed with the used paper liquid, mixed with a viscous agent, and the synthetic paper solution obtained from the papermaking machine is removed from the papermaking network, and then the finishing paper layer is laminated thereon if necessary, and these are the wallpaper containing the far-infrared radiation material. And a method for producing the same.

However, generally known far-infrared radiators such as elvan, zeolite, ocher, etc. are colored inorganic materials rather than pure white, and thus color limitations are revealed in products that need to express patterns on the wallpaper. In addition, the wallpaper containing the conventional far-infrared ray emitting material as described above is mostly in the case of simply adjusting the particle size of the far-infrared ray-radiating natural minerals, and thus there is a problem containing impurities such as heavy metals and toxins.

Various fungi such as molds and bacteria are present on the walls and floors of buildings, houses, hospitals, restaurants, etc., and they cause diseases in humans, as well as deterioration and decay of drugs and foods, and wallpaper and flooring. It damages the back and shortens the service life, causing economic losses. In particular, black mold (Aspergillus Niger), which is detected in large quantities in public places and residences, causes respiratory diseases or allergic diseases in humans, and is a major cause of visual discomfort and damage to the indoor environment due to proliferation.

Currently, antibacterial and antibacterial products such as various stationery and interior decoration materials have been developed, and in the case of wallpaper, products having antibacterial and antibacterial functions have been proposed, but their performance is extremely weak.

Korean Unexamined Patent Publication No. 1996-0014534 discloses a method for producing a wallpaper in which an antibacterial deodorizing effect is given by mixing an extract of scrubber and the like with a pulp slurry, and Japanese Patent Laid-Open No. 9-165309 discloses a surface layer of an interior decoration finish such as wallpaper. The method of using the resin pellet for coating of an antimicrobial function is proposed. In addition, the Republic of Korea Patent Publication No. 1998-019564 is coated with a binder containing an antimicrobial agent, ceramic on the backing paper and laminated a biodegradable plaster for showing a predetermined shape thereon, and further containing a far-infrared radiation substance and an antimicrobial agent A biodegradable wallpaper in which a top coat layer is formed is proposed.

However, the conventional antimicrobial and antibacterial wallpaper has only a far infrared ray emitting material or a far infrared ray emitting material and an inorganic antimicrobial agent, and its performance is extremely insignificant and unsatisfactory. In particular, the inorganic antimicrobial agent has the disadvantage that the antimicrobial effect is not great against fungi such as black mold (Aspergillus Niger).

The present invention is to solve the above problems, by applying the far-infrared fine powder bioceramic powder and organic nitrogen-based antimicrobial agent in the manufacture of wallpaper, humidity control, insect repellent, antibacterial, deodorization, warming effect and promoting blood circulation to the human body, The purpose of the present invention is to provide antimicrobial wallpaper containing far-infrared radiation substance that maximizes deodorization, antibacterial and anti-foaming effect, and manufacturing method thereof, as well as all-infrared radiation effects such as enhancement of metabolism, revival of tissue and fatigue recovery. .

It is a high purity product with a moisture content of.

In addition, the present inventors applied three types of organic nitrogen-based compounds as the antimicrobial agent to the mixed solution applied to the wallpaper base paper together with the fine powder bioceramic powder in order to maximize the antibacterial activity. The antimicrobial agent used in the present invention is an organic compound of three organic nitrogen-based and organic nitrogen-based sulfur compounds composed of octhilinone, zinc pyrithione, and carbendazim, and has the following characteristics.

Octylinone (C ₁₁ H ₁₉ N0S; 2-N-octyl-4-isothiazolin-3-one) exhibits strong activity in the chains of alkyl groups to which nitrogen groups (N-) are attached. It inhibits the biosynthesis of ergosterol, a precursor of vitamin D, which is needed at the growth stage.

Zinc salt of 2-mercaptopyridine-N-oxide (C ₁₀ H ₈ N ₂ O ₂ S ₂ Zn; Zinc salt of 2-mercaptopyridine-N-oxide) is widely used in cosmetics, polymer emulsions, latex paints, and chelating to make water-soluble stable compounds. It is a biomembrane-active microbiocides. In the cell membrane of microorganisms, there is a protein that absorbs nutrients from the outside of the cell, which binds the nutrients from outside the cell and transfers the active ingredient to the transport protein that moves inside the cell. It acts as a microbiocides by blocking the influx of nutrients into the furnace. In addition, it shows high activity against Gram-positive bacteria, which have a thick cell wall among bacteria and a simple influx of nutrients into the cells.

Carbendazim (C ₉ H ₉ N ₃ O ₂ ; methyl-N-benzimidazol-2-ylcarbamate or N-bezimidazol-2-ylcarbamic acid) is effective for plastic coatings, fungal and yeast of bacterial strains. It shows strong antibacterial activity, etc., and binds to amino groups of cells and amino groups of proteins to inhibit the activity of enzymes in vivo.

The organic compound active ingredient (Active Ingradient) having the above characteristics has an excellent activity inhibitory effect against various bacteria as shown in the following [Table 1] to [Table 3]. [Table 1] to [Table 3] shows the minimum inhibitory concentration (MIC) of each of the three types of organic compounds against different kinds of fungi, and shows the microbicides for the An excerpt from the materials provided by protection of materials, author: Wilfried Paulus, published by CHAPMAN & HALL.

Therefore, the antimicrobial wallpaper according to the present invention extends the shelf life of the product by suppressing the incubation of microorganisms such as bacteria and fungi by applying an organic nitrogen-based compound having an excellent antimicrobial activity in addition to the antimicrobial effect of the far-infrared radiation material. It can prevent product damage caused by mold or bacteria.

Hereinafter, a method for producing an antimicrobial wallpaper containing a far infrared ray emitting material according to the present invention will be described in detail.

first, As far porous materials, far-infrared radiation materials of silicon dioxide (SiO ₂ ), titanium dioxide (TiO ₂ ), zinc carbonate (ZnCO ₃ ), talc and kaolin have excellent whiteness, adsorption, deodorization and antibacterial effects. After firing at 1300 ° C. for 1 hour, the mixture is held for 24 hours in a kiln to allow aging. This process removes impurities such as heavy metals and toxins. As a result, no lead (Pb), cadmium (Cd), arsenic (As), or mercury (Hg) were detected (see Table 4).

Far-infrared bioceramic having undergone the firing process is formulated and blended for each material. The proper mixing ratio of far-infrared bioceramic material is 20 to 40% by weight of silicon dioxide (SiO ₂ ), 10 to 20% by weight of titanium dioxide (TiO ₂ ), 5 to 20% by weight of zinc carbonate (ZnCO ₃ ), and talc 5 20% by weight and 20-40% by weight of kaolin are preferred. Such a compounding ratio can be accompanied by the optimum expected effect such as excellent whiteness, adsorption, deodorization and antibacterial effect utilizing the function of each material. After mixing the appropriate proportion of the material in a blender for 2 hours or more, the agglomerated particles are pulverized into fine powder, and the classification operation is performed by using a vibrating body as an example for uniformizing the particles. Preferably, by having an average particle size of 2 ~ 3㎛ makes it easy to pass through the gap of the knife coater (knife coater) when applied to the wallpaper base paper to be evenly distributed on the wallpaper base paper.

5 ~ 10% by weight of the far-infrared bioceramic mixed powder (powder) having a uniform particle size, three organic nitrogen-based compounds consisting of octhilinone, occ pyrithione, and carbendazim, 0.2- 2% by weight and 30-40% by weight of binder, 20-30% by weight of plasticizer, 20-30% by weight of filler, 0.5-3% by weight of dispersant, 0.5-5% by weight of blowing agent, 0.5-3% by weight of stabilizer and other additives. 3-10 weight% of diluents and 5-10 weight% of pigments are mixed, and the mixed solution for apply | coating to a wallpaper base paper is obtained. At this time, the mixed solution is preferably stored for at least one day so as to be sufficiently swollen and applied to the wallpaper base paper.

The binder may be polyvinyl chloride (PVC), polyethylene (PE), or an acrylic system (for example, PVA) alone, or a mixture thereof. The plasticizer may be dioctylphthalate (DOP) or dioctyl adipate (DOA). ) Or tricresyl phosphate (TCP) may be used. As a filler, calcium carbonate (CaCO ₃ ) or the like can be used. As a dispersant, BYK-4040 (manufactured by BYK-CHEMIE, Germany), and an oxybisbenzene sulfonyl hydrazide series (oxybis) as a blowing agent. benzene sulfonyl hydrazide) or azodicarbonon amide may be used, and as a stabilizer, a barium-zn organic complex may be used. In addition, the other additive is a diluent for imparting the proper viscosity of the mixed solution, ISU D-SOL 200 (manufactured by Domestic Isu Chemical Co., Ltd.), YK D-80 (manufactured by KKD) or EXXON D-80 ( and the like US liquid Harn (社), Ltd.), a pigment may be used as the TiO ₂ and the like.

In a preferred mixing method for obtaining such a mixed solution, first, a blowing agent, a pigment, a dispersant, and a far-infrared bioceramic mixed powder are mixed in a plasticizer and milled to obtain a toner liquid. This is a process for improving the dispersibility, the milling operation may use a grinder or three-stage rolling machine. In addition, the organic nitrogen-based antimicrobial agent is first dispersed in a small amount of plasticizer, and finally, the antimicrobial agent and the plasticizer are mixed in a line work to uniformly disperse the organic nitrogen-based antimicrobial agent throughout the mixed solution to prepare an antimicrobial suspension. At this time, the composition ratio of the antimicrobial agent and the plasticizer was octylinone (C ₁₁ H ₁₉ N0S): jinpyrithione (C ₁₀ H ₈ N ₂ O ₂ S ₂ Zn): carbendazim (C ₉ H ₉ N ₃ O ₂ ): Preference is given to 10: 20: 10: 60 by weight of plasticizer (DOP). Subsequently, the plasticizer (DOP), stabilizer, and dispersant components are mixed and the toner liquid and the antimicrobial suspension are added while stirring at low speed, and at the same time, the binder and the filler are added and sufficiently stirred to form a complete paste. At the same time, a small amount of diluent is added to have a viscosity suitable for application to the wallpaper base paper.

The mixed solution thus prepared is evenly applied to the wallpaper paper (paper or nonwoven fabric) by a knife coater mounted on the wallpaper manufacturing apparatus having several interlocking rollers.

In addition, a gelling process for making a printable state of the mixed liquid solution applied to display the design on the wallpaper subsequent to the coating process, a printing process for displaying a desired design on the gelled surface, and a printed process. A foaming process for making a ready state capable of embossing on the surface and an embossing process for expressing a three-dimensional effect on the wallpaper and forming aesthetics are performed.

The gelling process is a process of passing the hot air chamber (chamber) in a process of making the liquid mixed solution applied to the wallpaper base paper into a printable solid state. At this time, the ambient temperature of the chamber is to be 170 ~ 200 ℃. At temperatures below 170 ° C., gelling takes a long time, and above 200 ° C., foaming occurs, making printing difficult. The printing process can be carried out at room temperature, but when the temperature is low, such as winter, work by maintaining a temperature of 60 ~ 80 ℃ using a drying hot air fan. This is for conveying by several interlocking rollers and working continuously so that the ink dries quickly so that there is no bleeding. In addition, the foaming (foaming) process is to form a ready state capable of embossing (gmbossing) by foaming (gelling) the printed surface and to give a heat insulation effect and light weight of the wallpaper 200 ~ 250 ℃ It is the process of passing the chamber of temperature. By maintaining the ambient temperature of the working chamber at 200 ~ 250 ℃ a plurality of pores are formed on the wallpaper surface. An embossing operation is performed in which the formed wallpaper is passed back through an embossing roll. At this time, it is good to maintain the temperature of the wallpaper surface at 150-170 degreeC. The wallpaper embossed as described above is dried by a drying hot air blower, and is cooled and wound to maintain the wallpaper surface at 35 ° C. or lower by performing a cooling operation. In addition, optionally, after drying, the top coating layer may be formed of an acrylic or urethane resin on the upper surface.
