The present invention relates to a wall paper having excellent durability and functionality, and a method for manufacturing the same, in particular, a clay clay containing a loess and germanium in a paper liquid containing a paper mulberry pulp, an anionic oligomer resin aqueous solution that does not absorb far infrared rays, It relates to a wallpaper having excellent durability and functionality, comprising a composition comprising a functional additive such as charcoal and one or more mucus selected from mussels, polyethylene oxide and the like as a mucus.

Looking at the wallpaper, which has been used conventionally for interior construction, wallpaper using chemical adhesives releases volatile organic compounds (VOC) and formaldehyde (HCHO), which are subjects of environmental regulation, to cause atopic dermatitis, headache, discomfort and allergy. It has been reported to cause sexual rhinitis. In addition, these substances are the causative agent of new house syndrome, which has recently been reported to take 2 to 5 years to remove the causative agent of sick house syndrome (Sick House Syndrome).

In order to solve these problems, attempts to develop eco-friendly functional wallpaper using natural additives that do not use volatile organic compounds and harmful substances such as formaldehyde, and adding functional additives that radiate far infrared rays and anions to sunny pulp or mulberry pulp. Has been made constantly.

As is widely known, far-infrared rays have been scientifically proven to be effective, and household products containing far-infrared radiation materials existing in the natural environment have been developed and released one after another, and various uses for far-infrared radiation materials have also been studied. Far-infrared rays are 30 ~ 1000 μ heat rays longer than visible rays and absorbed by the human body to activate cellular tissues and promote blood circulation and waste discharge. , Germanium, elvan, natural jade and the like are known.

In addition, as is well known, anions are reported to absorb and neutralize cations harmful to health released from various pollutants and oxides to facilitate metabolism of the human body, and to regulate autonomic nerves and enhance resistance. . Many types of cations such as cations from photochemical smog, cations from oxides generated inside muscles due to fatigue accumulation, cations from automobile exhaust gases, cations from pollutants, etc. Representative materials that emit anion, and include an earth mineral, germanium, tourmaline, natural jade, ganban stone, ocher, charcoal, silver, etc. Like the far infrared products, various products are being developed in accordance with the recent well-being hot air.

As for the wallpaper, the interior wall finishing material has been mainly foamed with polyester span bond or PVC on the backing paper or woven paper. However, in the case of such wallpaper, formaldehyde used in the manufacturing process remains. As a result of the problem of sick house syndrome, and also as described above, such as the preference for health-friendly and eco-friendly wallpaper, the preference for natural materials, and recently, there is an antibacterial, deodorant function such as ocher, germanium, charcoal, and health Attempts have been made to develop functional wallpaper or cardboard that emits far infrared and negative ions that are beneficial to the environment.

In addition, in developing a wallpaper or a sheet of paper with the addition of the functional material, attempts have been made to use paper mulberry pulp, which is a raw material of traditional Korean paper, instead of the conventional pulp used in the past. For example, Korean Unexamined Patent Publication No. 10-2004-49711 discloses a genus in which a functional additive such as ocher, charcoal, and germanium is added to the pulp at a 7 to 13% weight ratio to pulp, which is a raw material of traditional Korean paper. Korean Unexamined Patent Publication Nos. 10-2000-268 and 10-2006-40261 disclose a functional wallpaper in which far-infrared radiation material is added to a mulberry pulp. In addition, attempts have been made to maximize the effects of negative ions and far infrared rays, and Korean Patent Laid-Open Publication No. 10-2000-4011 discloses a far infrared ray radiator that emits far infrared rays by using a general conductive heating element and an epoxy plate.

However, conventional functional wallpaper containing a functional additive that emits far infrared rays and anions, although containing a large amount of functional additives, the anion and far infrared rays emitted from the functional additives pass through the backing layer, the foam layer which is a constituent layer of the wallpaper There has been a problem that the amount of anion and far-infrared radiation that are mostly lost in the process and actually radiated to the outside of the wallpaper is extremely small.In addition, when the functional additives such as ocher, germanium, and charcoal are added to the natural pulp, the binding strength is weak. By adding to the pulp, the bonding strength of the wallpaper constituent layer is weak, serious problems of durability, such as tearing or stamping, seriously produced, it was difficult to commercialize. In the case of wallpaper made of paper mulberry pulp, which is a material of Korean paper, not only the strength of Hanji itself is weak, but also the durability of the addition of inorganic additives, which is a functional additive, is severe, which makes it unsuitable for use as wallpaper for concrete finishing surfaces such as apartments. In order to solve this problem, a polymer material such as polyvinyl alcohol aqueous solution, vinyl acetate-vinyl alcohol copolymer, cellulose substituted with hydroxyl group, and the like is added to the paper mulberry pulp solution to solve durability problems such as tearing or chipping. Attempts have been made, but in order to improve the miscibility with the pulp paper liquid, which is an aqueous solution when the polymer resin is added, the content of a functional group such as a hydroxyl group or an acetate group must be increased in the polymer. To attenuate the far-infrared rays In addition, blocking the movement of anions causes a problem of deterioration of functionality.In the case of lowering the functional group content, the miscibility with the aqueous mulberry pulp is deteriorated, the polymer resin is separated, and the dispersibility in the aqueous solution is poor. When manufacturing the problem occurs that the workability is extremely bad. In addition, when the polymer resin is used, it was found that the compatibility with the aqueous solution deteriorates rapidly as the molecular weight increases.

In order to solve this problem, the present inventors have repeatedly conducted research and experiments. As a result, the inventors found that the paper liquid was mixed with an aqueous solution of anionic oligomer resin and mulberry pulp in which a functional group absorbing far infrared rays in the molecular structure was in a certain range. When used as a material was found to be able to manufacture a wallpaper that is excellent in durability while minimizing the attenuation of anion and far-infrared radiation dose and completed the present invention.

The present invention is a raw material of Korean paper mulberry pulp, ocher, which emits far infrared rays and anions in a paper liquid mixed with an oligomer resin having a functional group absorbing far infrared rays in a molecular structure of a certain range, germanium-containing wood clay, charcoal, etc. After the addition of the functional powder, the purpose is to provide an eco-friendly wallpaper excellent in functionality and durability made of a composition added with mucus, such as mussels, polyethylene oxide.

The configuration of the present invention for achieving the above object is attached to Figures 1 and 2, the specific configuration of the present invention is as follows.

The present invention, after adding functional additives such as ocher, germanium-containing wood clay, charcoal to paper stock consisting of an anionic oligomer resin having a functional group absorbing mulberry pulp and far-infrared rays, and then, mulberry, polyethylene oxide It is a wallpaper having excellent durability and functionality produced by adding a mucus such as the above.

When explaining the wallpaper of the present invention in more detail, 100 parts by weight aqueous solution of mulberry pulp, 10-15 parts by weight of anionic oligomer 3% aqueous solution having a functional group (absorbing far infrared rays) in a certain range, ocher, germanium-containing wood clay, Charcoal is a wallpaper consisting of a composition comprising 5 to 10 parts by weight of a functional additive made of charcoal, and at least one mucus selected from a mulberry, polypolyethylene oxide, and the like.

Below, the component of this wallpaper is demonstrated in detail.

The present invention attenuates the radiation amount of far infrared rays and anions emitted from ocher, germanium-containing wood clay, charcoal by adding an anionic oligomer solution having a functional group absorbing far infrared rays to a mulberry pulp which is a raw material of traditional Korean paper. The present invention relates to a wallpaper having improved durability such as tearing or bleeding at the same time without making it described. The anionic oligomer aqueous solution used in the present invention will be described in order as follows.

<Anionic Oligomer Resin Aqueous Solution>

In the case of the conventional wallpaper which emits far infrared rays and anions, even if a large amount of far infrared rays or anion radioactive materials such as ocher, germanium and charcoal are added to the natural pulp, the far infrared rays and anions radiated from these functional additives may form the back layer of the wallpaper and foam. Since it is absorbed and blocked by the resin in the process of passing through the layer, it is known that the far infrared rays or negative ions emitted from the wallpaper to the room are extremely small. In the present invention, in order to minimize the reduction of far infrared rays generated in the process of passing through the wallpaper layer, the polymer has a functional group content of -OH, -NH, -SH, -OR, etc. that absorbs far infrared rays in the molecular structure of the oligomer resin. It is limited to 1 to 5 mol% based on the entire resin, and -COONa, -COOCa, -COOMg, SO ₃ Na, SO ₃ Ca, SO ₃ Mg, etc. in order to smooth the flow of anions in the process of passing through the wallpaper layer. 10 to 20 mol% of the anion of the oligomer resin is included, and an anionic oligomer having a number average molecular weight of 1,000 to 2,000 is used as the resin. When the content of functional groups such as -OH, -NH, -SH, and -OR absorbing far infrared rays is less than 1 mol%, the miscibility of oligomer resins, mulberry pulp, and functional inorganic particles becomes worse, and it is more than 5 mol%. In this case, the radiation amount of far-infrared rays emitted is drastically reduced. When the anionic group is included in less than 10 mol%, the permeability of the emitted anion is not improved. When the anionic group is included in more than 20 mol%, the permeability of the anion is improved, but the flexibility of the oligomer resin is reduced, and the aging of the resin with respect to heat or light is reduced. The phenomenon occurs badly. Examples of the anionic oligomer resin include metal salts of polyvinylacetate having a number average molecular weight of 1,000 to 2,000, metal salts of polyethylene-vinylacetate copolymer, metal salts of polymethyl methacrylate, metal salts of polyethylene-methyl methacrylate copolymer, and the like. Can be mentioned. Metal salts may include Na, Ca, Mg and the like. In the case of using a polymer resin having a large molecular weight, the durability of the wallpaper is improved, but there is a problem in that the miscibility with the paper mulberry pulp is worse. In addition, the anionic oligomer resin aqueous solution uses a 3% aqueous solution. The amount of the anionic oligomer resin is added in an amount of 10 to 15% based on the dry weight of the mulberry pulp.

<Takwood Pulp>

The pulp used as the paper stock of the present invention is a paper pulp, which is a raw material of traditional Korean paper, and its manufacturing process is as follows. First, in order to extract the white skin from the natural mulberry, the annual cut mulberry in winter is contacted with steam in the steam furnace for more than 5 hours so that the mulch can be peeled off well. Second, peel off the black skin, the bark of the paper mulberry taken out of the steam furnace. Third, the dark skin is soaked in water for more than 12 hours, soaked, and the white skin is completely removed from the outer shell and the inner blue shell, and submerged in water for two days or more. Third, the white skin is cut into small pieces, and then submerged in a caustic soda solution to remove impurities from the white skin by submerging in caustic soda or lye at pH 9.5 or higher. Fourth, the white pulp is washed and pulp is made by using a machine such as a motor for a long time to make it soft. In the process of manufacturing the mulberry pulp, it is possible to adjust the residence time or pH in each step, as needed.

<Functional additive>

As functional additives that emit infrared rays and anions, ocher, germanium-containing wood clay, and charcoal are added in an amount of 5 to 10% by weight based on the dry weight of the mulberry pulp.When the amount exceeds 25% by weight, the radiation rate of far infrared rays and anions is high. However, the flexibility and durability of the wallpaper is poor, and if the addition amount is less than 10% by weight, the flexibility and durability of the wallpaper is improved, but the radiation amount of far infrared rays and anions is drastically reduced. Ocher, germanium-containing wood clay and charcoal are dried for a long time at 200 ℃ or more to remove moisture, heat-treated at 500 to 600 ℃, which is below the temperature to decompose or melt, and then the sieve rate is over 60% in 300 mesh strainer. Mill in the grinder until The addition ratio of ocher: germanium-containing wood clay: charcoal is preferably 3: 4: 3, and the functional additive is added in an amount of 5 to 10% by weight based on the dry weight of the mulberry pulp.

<Slime solution>

As a slime agent to reinforce the binding force between the functional additives and the mulberry pulp, one or more selected from among mulberry, which is widely used in making paper of Hanji, or polyethylene oxide, which is a synthetic product, may be added. The amount of the mucus added is 0.1 to 0.5% by weight relative to the stock solution including the mulberry pulp, functional additives and polymer aqueous solution.The amount of the mucus added depends on the temperature and humidity, the dispersion of the mulberry pulp, and the dispersion of the anionic oligomer solution. Since it is sensitively changed, within an amount of 0.1 to 0.5 parts by weight based on 100 parts by weight of the paper liquid, depending on the case, an appropriate amount is added.

<Other functional additives>

In addition to the additives described above, functional additives such as emulsifiers, zeolites, and silver may be further included in consideration of the specific use of the final wallpaper or the change over time according to the climate. If anionic oligomer resin, paper mulberry pulp and functional additives are poorly miscible, a long time after wallpaper construction may occur, and the additives dispersed in the wallpaper layer migrate to the wallpaper surface, causing staining. In this case, an emulsifier such as sodium stearate may be added. In addition, when it is necessary to add a deodorizing or antibacterial effect to the wallpaper according to the city factory, a certain amount of zeolite particles having a deodorizing effect or silver having an antimicrobial effect may be included. Silver is superior to charcoal, but the antimicrobial agent is economically disadvantageous, so antimicrobial is mainly used, and it is preferable to include only a small amount of silver.

Hereinafter, the manufacturing method of the wallpaper of the present invention will be described step by step, and a manufacturing step of adding an anionic oligomer aqueous solution and a functional additive to a conventional manufacturing method of Hanji is added.

First step (mixing of pulp, pulp, anionic oligomer solution and functional additives)

A mulberry pulp, an anionic oligomer 3% aqueous solution was prepared as described above, and added to the mulberry pulp stock solution, and then kneaded at 1000 rpm dynomil to completely disperse the stock solution for 30 minutes to 1 hour. The solid content of the paper liquid is influenced by the use of the wallpaper to be produced, the thickness of the wallpaper, the degree of dispersion of the pulp in the aqueous solution, the type of oligomer resin to be added, and the like. The content of solids cannot be determined uniformly, and it must be determined fluidly after evaluation of the pumbil by producing grass paper from grass paper. Typically, the composition ratio of solids consists of 10-15 parts by weight of anionic oligomer resin and 5-10 parts by weight of functional additives in 100 parts by weight of dry pulp, and the content of solids is determined as described above. It is desirable to adjust fluidly in consideration of quality, thickness of papermaking, continuity of papermaking, viscosity of paper stock, and the like.

Second step (addition and stirring of mucus)

Some of the functional additives in the first stage paper liquor adhere to the cilia of the pulp, but most of the particles have a higher specific gravity than the paper liquor and settle down over time. In order to solve this problem and fix most of the functional additive particles to the pulp cilia, a mucus should be added to the stock liquid. As the mucus, one or more selected from among the green grass and polyethylene oxide used for making paper of Hanji can be used. When the viscous agent is added to the paper liquid and stirred, the functional additive particles precipitated below rise up and adhere to most of the pulp cilia. The amount of the mucus added may vary depending on the type of pulp, the mixing ratio of water and pulp, the degree of high resolution of the pulp, the content of the polymer resin in the paper liquid, the thickness of the wallpaper, the production speed, etc., but it is typically 0.1 to 0.5% by weight of the paper liquid. Degree is preferred.

Third Step (Paper Processing)

The paper liquid prepared in the first to second stages is a process of scooping out using the papermaking network of the paper machine.

The papermaking method can be both long and cyclic, but in the case of the present invention in which the functional additive is added, the cyclic is preferable.

4th step (drying, calendaring and finishing)

After drying the papermaking prepared in the first to third steps in a dryer, it passes through a calendering step of pressurizing with a pressure roller. If necessary, calendaring may not be performed to maintain the natural aesthetic of the wallpaper. The wallpaper which has undergone the calendering process may pass through the embossing roll to give the surface aesthetic appearance to the convex unevenness, or may pass through the printing roll to print a beautiful pattern.

In the IR absorption intensity of Table 2, in Comparative Examples 2 and 3, where the content of the far-infrared absorption functional group of the anionic oligomer is high, the absorption of far-infrared rays occurs strongly inside the wallpaper layer, and the radiation rate of the far-infrared rays is drastically reduced. It can be seen that the electrical resistance indirectly confirmed that in Comparative Examples 1 and 2, in which the metal salt of the anionic oligomer was not added, the electrical resistance was very high and anion emitted from the functional additive was difficult to pass through the layer of the wallpaper. In the case of Comparative Example 1, in which the anionic oligomer is not added, the tensile strength is low, and the durability, such as tearing or chipping, becomes poor. In Comparative Example 4, the metal content of the anionic oligomer metal salt is increased. Increasing tensile strength is small, it can be seen that the durability worsens. That is, in Comparative Example 1, in which the oligomer metal salt is not added, the tensile strength is poor and the durability is poor, whereas in Comparative Example 2 in which the polymer PVA having a large number average molecular weight is added instead of the oligomer, the electrical resistance is high and the dispersibility in the paper liquid is poor. When the content of the hydroxyl group of the anionic oligomer exceeds a certain range, it can be seen that the comparative example 3 strongly absorbs the far infrared and the far-infrared emissivity decreases rapidly, and the metal salt ratio of the metal salt of the anionic oligomer In the case of Comparative Example 4 exceeding a certain range it can be seen that as the metal component increases, the tensile strength decreases rapidly, resulting in poor durability.

As described above, a solution of an anionic oligomer, an aqueous solution of metal salts of anionic oligomers, and a clay solution containing ocher, germanium-containing wood clay, and charcoal added to one or more mucus selected from camphor, polyethylene oxide, etc. It can be seen that the wallpaper not only has excellent durability such as tearing and stamping, but also maximizes radiation of far infrared rays and anions.
