Description

Natural material composition for wallpaper having flame retardant and electromagnetic wave blocking effect, wallpaper using same and manufacturing method thereof

The present invention relates to a natural material composition for wallpaper, a wallpaper and a method of manufacturing the wallpaper using the same, more specifically, flame retardant (flame retardant) and electromagnetic wave blocking effect, as well as flame retardant having the function of humidity control, deodorization, antibacterial And it relates to a natural material composition for wallpaper having an electromagnetic wave blocking effect, wallpaper using the same and a method of manufacturing the wallpaper using the same.

In general, most wallpaper is widely used to apply a synthetic resin material containing various chemicals to the surface of the paper, etc. in order to enhance the aesthetic effect and to improve the quality of quality, and then various figures or paintings on this surface. It is prepared by printing.

Such wallpaper is usually attached to a mortar-finish finish in which sand, cement, and water are mixed in an appropriate ratio on a concrete wall or a wall constructed by masonry to form an interior wall.

In this case, the mortar finish surface may be painted with various kinds of wallpaper, but may be applied by applying various types of paint directly, or may be finally finished using a secondary finishing material composed of wood or resin materials.

However, the finishing material is cement, the main component is a significant amount of toxic emissions from it, even if wallpaper is wallpaper can not prevent the release of harmful components. In addition, even when interior materials or interior materials other than wallpaper are used, they are inhabited on wood as well as harmful gases including volatile organic compounds (VOCs) from synthetic adhesives, PVC, resins, etc., which are used when applying or installing them. Toxic insects have a significant adverse effect on the body and indoor environment of people living in the interior space.

Toxic and toxic gases of cement not only cause significant damage to users 'eyes, nose and bronchus, but also cause various skin diseases such as adverse effects on users' skin. In recent years, these symptoms are called sick house syndrome. . In particular, in the event of a fire, toxic gases are released in a large amount by the finishing materials of various synthetic materials, causing a lot of casualties.

On the other hand, homes and offices are equipped with a variety of electronic devices such as televisions, computers, microwave ovens to generate a large amount of electromagnetic waves, and the fact that they have a bad effect on the body has been proved through various experiments.

Various functional wallpaper or finishing materials have been developed to create a safe indoor environment from harmful substances and electromagnetic waves as described above. For example, recently, a method of coating with ocher-containing wallpaper or coating a finishing agent with a neutralizing agent that can neutralize harmful substances has not been solved.

Accordingly, in recent years, technologies for wallpaper to block the toxicity and harmful gases of cement have been developed.

As one example, a technology has been developed for a natural wall paper produced by applying a natural material composition formed of a precious stone powder, sericite, and a natural adhesive on a raw paper.

However, since the natural wall is burned immediately in the event of a fire, the residents can not afford the time to evacuate to the outdoors, and can not provide stability to the fire, but also cut off the electromagnetic waves that are harmful to the human body in normal times. There is no limit.

As another example, a technique has been developed for a fabric material flame retardant fabric produced by mixing and stirring a predetermined amount of germanium powder, tourmaline powder, flame retardant, binder to the fabric material base.

However, the flame-proof wallpaper can prevent the wallpaper from burning within a predetermined time, but if the flame is continuously generated, there is a problem in that eventually it is combusted to discharge a large amount of gas including toxic gas.

Republic of Korea Patent Registration No. 10-0445039 (August 21, 2004) Republic of Korea Patent Publication No. 10-2010-0087847 (2010.08.06 published)

Therefore, the first object of the present invention is used in the wallpaper to delay the combustion of the wallpaper by the flame, does not emit toxic gas even when burned, not only block the electromagnetic waves in normal, but also flame retardant to emit anion and far infrared rays beneficial to the human body It is to provide a natural material composition for electromagnetic wave blocking wallpaper.

It is a second object of the present invention to provide a method of manufacturing a flame retardant and electromagnetic wave blocking wallpaper using the above-described natural material composition for flame retardant and electromagnetic wave blocking wallpaper.

In addition, a third object of the present invention is to provide a method for manufacturing a flame retardant and electromagnetic wave blocking wallpaper using the above-described natural material composition for flame retardant and electromagnetic wave blocking wallpaper.

In order to achieve the first object of the present invention described above, in one embodiment of the present invention, flame retardant and electromagnetic shielding comprising 35 to 50% by weight of water, 35 to 50% by weight of sericite, and 7 to 15% by weight of the adhesive. It provides a natural material composition for wallpaper.

In order to achieve the second object of the present invention, the present invention is a natural material composition comprising a paper and 35 to 50% by weight of water, 35 to 50% by weight of sericite, and 7 to 15% by weight of the adhesive is 0.1 to It provides a flame-retardant and electromagnetic wave blocking wallpaper comprising a 0.5mm applied natural material composition coating layer.

In addition, in order to achieve the third object of the present invention, the present invention (i) 40 to 50% by weight of the sericite, 7 to 15% by weight of the adhesive and 35 to 50% by weight of the water uniformly natural wallpaper composition for wallpaper Preparing a; (Ii) combining the plurality of sheets of paper to produce a paper; (Iii) applying the wallpaper-based natural material composition to a thickness of 0.1 to 0.5 mm on the paper; And (iii) provides a method for producing a flame-retardant and electromagnetic wave blocking wallpaper comprising the step of drying the composition applied to the paper.

The natural material composition for flame retardant and electromagnetic wave blocking wallpaper according to the present invention has flame retardance to itself and thus delays combustion of the wallpaper in case of fire. This ensures minimum safety for the occupants by delaying the spread of flames from the original source during the evacuation of the occupants.

The natural material composition for flame retardant and electromagnetic wave shielding wallpaper uses natural ore-based flame retardant instead of flame-retardant chemicals that cause harmful gases such as organic halides. This is minimized. That is, the present invention can suppress secondary damage such as respiratory damage by harmful gas.

In addition, since the present invention uses only sericite alone, excluding the use of other minerals, the preparation is easy, the stability of the composition is increased, and the mixing is easy.

In addition, the present invention does not need a separate wallpaper pattern forming process, and because the use of the paper surface smoothness is improved, and excellent durability.

Moreover, the wallpaper using the natural material composition for flame retardant and electromagnetic wave blocking wallpaper according to the present invention not only emits a large amount of negative ions and far infrared rays which are beneficial to the human body, but also does not emit harmful substances harmful to the human body using only natural materials for hygienic and safe health. Can provide life.

Furthermore, the method for manufacturing a flame retardant and electromagnetic wave blocking wallpaper according to the present invention can uniformly form a flame retardant layer composed of a natural material composition for flame retardant and electromagnetic wave blocking wallpaper on the surface of the paper, and for the flame retardant and electromagnetic wave blocking wallpaper from the surface of the paper. The natural material composition can be prevented from being separated.

On the other hand, as a result of the actual experiment, the wallpaper has an electromagnetic wave blocking effect can reduce the adverse effect on the human body by the electromagnetic waves generated in various electronic devices, such as home or office. In addition, since the natural material composition including the natural ore is coated in a relatively thick state, effects and durability of indoor humidity control, deodorization, antibacterial, and air purification can be expected.

Hereinafter, with reference to the accompanying drawings will be described in detail a natural material composition for flame retardant and electromagnetic wave blocking wallpaper according to the preferred embodiments of the present invention, a wallpaper using the same and a method of manufacturing the same.

The natural material composition for flame retardant and electromagnetic wave blocking wallpaper according to an embodiment of the present invention may include water, sericite, and an adhesive used as a solvent, and may further include an additive and a quartz powder.

Each of these components functions jointly through a chemical action on each other. Therefore, the present invention can be said to have a specific combination of various composition combinations and combinations thereof, rather than depending only on a specific functional ingredient.

Flame retardant and electromagnetic wave blocking wallpaper according to an embodiment of the present invention comprises a natural material composition.

The water is environmentally friendly and has colorless, tasteless and odorless properties. In the present invention, soft water, distilled water, deionized water, or purified water may be used, and preferably, purified water is used.

In this case, the amount of water used may be adjusted according to the type and amount of the other components, or the method or use of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper. In particular, the present invention can be selected from the range of about 35 to 50% by weight based on 100% by weight of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper to uniformly and smoothly applied to the surface of the wallpaper, preferably 40 to 45 It is recommended to use weight percent.

When the content of water is less than 35% by weight in the natural material composition for flame retardant and electromagnetic wave blocking wallpaper, not only each component of the composition is easily mixed, but also its own viscosity is high, it is difficult to smoothly apply to the surface of the wallpaper. On the contrary, when the content of water is more than 50% by weight in the natural material composition for flame retardant and electromagnetic wave blocking wallpaper, the viscosity is lowered and the adhesive force of the adhesive is reduced, making it difficult to apply uniformly to the surface of the wallpaper, and the time required for drying is increased. As a result, productivity decreases.

The natural material composition for flame retardant and electromagnetic wave blocking wallpaper according to an embodiment of the present invention includes sericite (Cicada).

Sericite, the main raw material of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper of the present invention, promotes blood circulation in the human body, emits 90% or more of far infrared rays activating cellular activity, and emits strong anions to adsorb various harmful substances. As a material having a function, 35 to 50% by weight based on 100% by weight of the total material composition for flame retardant and electromagnetic wave blocking wallpaper.

When the content of sericite in the natural material composition is less than 35% by weight, it is possible to provide sufficient negative ions and far infrared rays to the people living inside the building, but it is difficult to impart flame retardance (flame retardancy) to the wallpaper. When the content of sericite exceeds 50% by weight, the content of other components is lowered and the overall physical properties are lowered.

The sericite constitutes the majority of the flame retardant layer formed of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper through the drying process in which the water is evaporated, thereby providing a flame retardant and electromagnetic wave blocking function to the wallpaper. For example, if less than 70% by weight of sericite is included in the flame-retardant layer in the water-dried state, it may emit anion at a level capable of emitting far infrared rays useful to the human body and adsorbing harmful substances. It does not provide flame retardancy or sufficient electromagnetic wave blocking effect.

On the other hand, the sericite may be used a sericite powder or a sericite aqueous solution.

In one embodiment, the sericite powder is crushed sericite to 200 to 500 mesh in the crusher, when the average particle size of the sericite powder is less than 200 mesh, the mixture of water and sericite powder does not gel properly, sericite When the average particle size of the powder exceeds 500 mesh, the physical properties of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper are not improved in preparation for the grinding cost of the sericite powder.

In another embodiment, the aqueous solution of sericite is a supernatant obtained by stirring and then solid / liquid separation of the sericite mixture of sericite powder and purified water.

Specifically, the aqueous solution of sericite is a supernatant obtained by stirring a sericite mixture mixed with 100 parts by weight of sericite powder and 100 parts by weight of purified water at room temperature for 30 to 90 minutes and separating from the slurry. If necessary, the aqueous solution of sericite may be used by filtering the supernatant according to a known technique.

If the sericite powder used in the aqueous solution of sericite is less than 10,000 mesh, the sericite mixture is not matured properly. If the sericite powder exceeds 12,000 mesh, the physical properties of the sericite aqueous solution are further increased compared to the increase in the crushing cost of sericite. It doesn't work.

Flame retardant and electromagnetic wave blocking wallpaper according to an embodiment of the present invention comprises a natural material composition.

The adhesive serves to increase the bonding force between the sericite powder particles as the main raw material. In addition, it was used to attach the natural material composition for flame retardant and electromagnetic wave blocking wallpaper to the paper (paper) of the wallpaper, and includes 7 to 15% by weight based on 100% by weight of the total natural material composition for flame retardant and electromagnetic wave blocking wallpaper. . Here, the paper generally means that two or more sheets of original paper used for wallpaper are used.

When the content of the adhesive is less than 7% by weight, the adhesive strength is lowered and does not adhere smoothly to the base paper.If the content of the adhesive is more than 15% by weight, cracks may occur after drying, and the amount of sericite is relatively reduced, resulting in the The functionality of the wallpaper by the site is degraded.

Flour paste, natural latex, gelatin or mixtures thereof may be used as the adhesive. In addition, a commercially available natural adhesive may be used as the adhesive.

All of them are derived from natural materials, not synthetic compounds, and inherently inhibit the generation of harmful components of volatile organic substances (VOCs) such as formaldehyde which is volatilized in conventional chemical synthetic resins.

On the other hand, in order to give a variety of colors to the wallpaper can be used by mixing the natural dye in addition to the adhesive. Such dyestuffs can be used by appropriately changing the addition ratio according to the concentration of color.

The natural dye may be a vegetable dye such as gardenia, yellowish white, saffron, turmeric, indigo, pine needles or the like, or animal dyes such as cochenille, kermes, or mineral dyes such as bengala, podium, or navy. Can be used.

In particular, in order to form a pattern having a variety of colors on the wallpaper, to express the color of the yellow system, Seok Ungwang (石 雄黃), Dong Huang (銅 黃), Yellow Dan (黄丹), to express the color of the red system For this purpose, pigments of Dang Zhu (연 朱紅), Yanji, Lime Liquor (石 澗 朱), and Burn Zhu (燔 朱紅) can be used. In addition, the lower lobe, stone green, three green and cerebrum are used to express the green color, and blue and green colors are used to express the color of the blue color. Cheonghwamuk (이 花 墨), Yicheng (二 靑), Samcheong (三 靑) can be used. In addition, in order to express the color of the white system, Jinjin (정) can be used to represent the color of the black system.

The natural material composition for flame retardant and electromagnetic wave blocking wallpaper according to an embodiment of the present invention may further include quartz powder.

The quartz powder is provided to assist the flame retardancy imparted to the wallpaper by a large amount of sericite, and includes 5 to 10 wt% based on 100 wt% of the total natural material composition for flame retardant and electromagnetic wave blocking wallpaper. In this case, the quartz powder may be a quartz powder having an average particle diameter of 100 to 300㎛.

When the content of the quartz powder is less than 5% by weight, it is difficult to achieve a function of assisting the flame retardancy imparted to the wallpaper by sericite, and when the content of the quartz powder exceeds 10% by weight, the natural material composition for flame retardant and electromagnetic wave blocking wallpaper is used. As the amount of sericite used is reduced, the amount of negative ions and far-infrared rays is reduced, making it difficult to color the wallpaper.

In addition, the quartz powder has excellent surface strength to prevent wallpaper from being damaged by external impact, and the surface pore is small, so it is excellent in fouling resistance. Safe from the propagation of bacteria

The natural material composition for flame retardant and electromagnetic wave blocking wallpaper according to an embodiment of the present invention may further include an additive.

The additive is added to the natural material composition for flame retardant and electromagnetic wave blocking wallpaper to improve the fluidity or enhance the properties of the final mixture, and may be used as long as it is added to the composition applied to the wallpaper used as a finishing agent in buildings. However, it preferably comprises a mixture of any one or more selected from the group consisting of thickeners, dispersants, antifoams, antibacterial agents.

In a particular embodiment, the natural material composition for flame retardant and electromagnetic wave blocking wallpaper has 0.3 to 0.6 wt% thickener, 0.5 to 0.8 wt% dispersant, 0.05 to 0.2 wt% defoaming agent, 0.3 to 0.7 wt% based on 100 wt% An antimicrobial agent, or an additive consisting of a mixture thereof may be included.

Specifically, the thickener is used to increase the viscosity of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper, it is preferable to use starch, or hydrophilic clay gelling agent. If the content of the thickener is less than 0.3% by weight, the viscosity of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper is lowered, and if the content of the thickener is more than 0.6% by weight, the viscosity of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper is increased and uniform. One application becomes difficult.

The dispersant is to promote the dispersion of natural dyes and to inhibit the separation of sericite and the adhesive, acrylic acid copolymer sodium salt, carboxylic acid ether, aromatic amino sulfonic acid, polyalkylaryl sulfonic acid, Naphthalene sulfonic acid may be used, and it is preferable to use acrylic acid copolymer sodium salt. If the content of the dispersant is less than 0.5% by weight, the dispersing capacity is lowered, making it difficult to prepare a uniform composition, and when the content of the dispersant is used in excess of 0.8% by weight, the dispersing speed may increase, resulting in poor quality.

The antifoaming agent serves to lower the surface tension of the natural disinfectant composition for wallpaper to remove bubbles, and it is preferable to use an organic antifoaming agent. In addition, if the content of the antifoaming agent is less than 0.05% by weight foam is difficult to uniformly apply, if the content of the antifoaming agent exceeds 0.2% by weight it will not be able to obtain a significant effect compared to the amount used.

As the antimicrobial agent, propolis, phytoncide extract or a mixture thereof may be used. These ingredients play an important role in the prevention of mold and in purifying odors caused by the living environment in order to create a better pleasant environment. In addition, when the content of the antimicrobial powder is less than 0.3% by weight, the antimicrobial activity of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper is lowered, and when the content of the antimicrobial powder is more than 0.7% by weight, the mechanical properties of the natural material composition for flame retardant and electromagnetic wave blocking wallpaper Not only is this lowered, the cost is higher.

And the present invention provides a flame-retardant and electromagnetic wave blocking wallpaper.

The wallpaper includes a paper prepared by first bonding two sheets of paper.

And a natural material composition coating layer formed by applying the natural material composition described above to the paper. As described above, the natural material composition comprises 35 to 50% by weight of water, 35 to 50% by weight of sericite, and 7 to 15% by weight of the adhesive, and optionally further comprises 5 to 20% by weight of quartz powder, In addition to this, it may further comprise 0.3 to 0.6% by weight of thickener, 0.5 to 0.8% by weight of dispersant, 0.05 to 0.2% by weight of antifoaming agent, and 0.3 to 0.7% by weight of antibacterial agent.

The pre-combustion composition coating layer is applied to the paper 0.1 to 0.5mm. If the thickness of the coating layer is less than 0.1 mm, the functionality of the wallpaper, i.e., flame retardant, electromagnetic wave blocking, or the like cannot be achieved, and in particular, a decrease in smoothness caused by moisture or the like during construction cannot be prevented. On the contrary, when the coating exceeds 0.5 mm, a problem arises in that the thick coating layer breaks when the wallpaper is handled, and the weight per unit area of the wallpaper increases, resulting in a problem that the wallpaper does not adhere to the wall and strays off.

This coating layer may be coated with 0.1 to 0.5mm through one application. When the natural material composition is applied, not only the flame retardant and electromagnetic wave blocking effects can be achieved, but also the effects and durability of indoor humidity control, deodorization, antibacterial and air purification can be expected. As described above, in the case of forming the coating layer by one application, the process is simple, the production efficiency is improved, and there is an advantage that the manufacturing cost can be reduced.

In addition, the coating layer may be formed by dividing the coating layer selectively two or more times. For example, when apply | coating twice, it will contain the 1st application layer apply | coated 0.07 to 0.4 mm, and the 2nd application layer apply | coated 0.03-0.3 mm. At this time, it is preferable to apply so that the primary coating thickness is thicker than the secondary coating thickness.

This is because when the coating layer is formed by one coating, it takes a long time to dry the coating layer, and it is difficult to apply the coating layer with a uniform thickness at one time, and a problem that the bonding strength between the coating layer and the paper is weakened occurs. . In addition, the probability of cracking in the coating layer is increased in the process of drying out moisture inside the thick coating layer. Furthermore, since moisture escapes from the inside of the coating layer, the coating layer is formed in a dense and sparse state, and the coating layer may be easily damaged.

Therefore, it is more preferable to divide the said application layer into two or more times, and to form in two or more layers.

An embodiment of a method of manufacturing a natural material composition for flame retardant and electromagnetic wave blocking wallpaper of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a method for manufacturing a flame retardant and electromagnetic wave blocking wallpaper according to an embodiment of the present invention.

This step can be applied to the laminated sheet of flame retardant and electromagnetic wave shielding natural material composition at a time of 0.1 to 0.5mm in thickness.

When the natural material composition is applied, not only the flame retardant and electromagnetic wave blocking effects can be achieved, but also the effects and durability of indoor humidity control, deodorization, antibacterial and air purification can be expected. As described above, in the case of forming the coating layer by one application, the process is simple, the production efficiency is improved, and there is an advantage that the manufacturing cost can be reduced.

Alternatively, the paper may be optionally coated in two or three times in thin thickness.

Here, applying the natural material composition for flame retardant and electromagnetic wave blocking wallpaper two to three times, as described above, to uniformly form the thickness of the natural material composition applied to the surface of the paper when applying the whole only once This is because it is not easy, and the adhesion between the paper and the natural material composition may be lowered.

Specifically, it may include the step of first coating on the paper with a thickness of 0.07 to 0.4mm and drying it, and then second coating on the paper with a thickness of 0.03 to 0.3mm.

In addition, in this step (S300), in order to give a color to the wallpaper, the natural material composition for flame retardant and electromagnetic wave blocking wallpaper and the natural material composition for flame retardant and electromagnetic wave blocking wallpaper may be sequentially applied.

More specifically, the applying step (S300) according to the present invention is a step of first applying a natural material composition for flame retardant and electromagnetic wave blocking wallpaper to a thickness of 0.07 to 0.4㎜ on the paper, and the first flame-retardant and electromagnetic wave blocking wallpaper The natural material composition for flame retardant and electromagnetic wave blocking wallpaper mixed with natural dyes or inorganic pigments on the surface of the natural material composition for one or two times to a thickness of 0.03 to 0.3㎜.
