Mat containing graphene and method of manufacturing the same {MAT CONTAINING GRAPHENE AND MANUFACTURING METHOD THEREOF}

The present invention relates to a mat containing graphene and a method of manufacturing the same. More specifically, the present invention relates to a mat containing graphene and manufacturing a mat by using a fabric containing graphene and laying a graphene carbon-coated heat ray to increase the thermal insulation of the mat and reduce far-infrared radiation.

Bedding plays a role in helping people sleep more comfortably and comfortably when sleeping or resting. By sleeping after a day's daily activities, people relieve fatigue and physically relax when resuming activities the next day. Allows for phosphorus charging. Accordingly, bedding is made of soft and fluffy fabric to preserve body temperature and compensate for the discomfort of hard floors. By using bedding made of these fabrics, people can maintain body temperature while sleeping and can sleep comfortably due to the soft and fluffy texture.

In general, bedding such as mattresses, blankets, pads, mattress covers, etc. are formed to have a certain thickness to help maintain body temperature during sleep. For example, they are made up of a cushion part such as cotton and a fabric surrounding the cotton to accommodate the cushion part. It is formed so that the warming effect of cotton can be obtained.

At this time, the cloth surrounding the cotton is a part that is in direct contact with the human body, and generates static electricity due to friction between the cloth and the cloth or the human body. This static electricity dries the skin and causes itching. In addition, it causes discomfort when static electricity is generated, causing dissatisfaction to users. To prevent this problem, substances such as antistatic agents are added when weaving cloth, but a sufficient effect of removing static electricity is not obtained through this. .

Meanwhile, in the field of textile products, technology development research has been conducted for a long time to improve the functionality of textile products themselves, and in particular, new functional textile materials that exert useful effects on the human body are constantly being developed and released.

Among these functional textile materials, in recent years, materials with far-infrared radiation functions that exert useful effects on the human body, such as promoting blood circulation in the human body, have been in the spotlight. In general, far-infrared fibers and fabrics are sensitive to body temperature and external factors due to the various minerals they contain. Visible light radiates far-infrared rays in the wavelength range that can be absorbed by the body's fluids, which activates the body fluids that make up most of the body and has a warming and warming effect, affecting blood circulation and secreting sweat within the body. It is known to play a role in promoting metabolism.

To provide this function, far-infrared ray-emitting fibers were manufactured by coating materials such as germanium, monazite, and tourmaline on fibers or fabrics or adding them to the spinning solution of the fibers. However, recently, radioactivity has been released from these materials, making clothing It has been evaluated as unsuitable for use as textile products such as bedding and automobile interior materials, so there is a need to develop new fabric products with far-infrared radiation effects.

The graphene fabric 110 used in the graphene-containing mat 10 of the present invention is a fabric or knitted fabric manufactured using graphene yarn. The graphene contained in the yarn increases the thermal insulation of the fabric and emits far-infrared rays. It promotes blood circulation and has the advantage of alleviating skin diseases such as dry skin, itching, and atopic dermatitis by absorbing and dissipating microcurrents such as static electricity flowing through the mat or the human body.

As shown in Figures 1 to 4, the mat 10 containing graphene according to the present invention is coupled to an upper mat 100 containing graphene fabric 110 and a lower part of the upper mat 100. It may include a lower mat 200 and a graphene carbon-coated heating wire 300 installed between the upper mat 100 and the lower mat 200.

The upper mat 100 includes a graphene fabric 110, an upper cushioning portion 120 coupled to the graphene fabric 110, and an upper laminating adhesive portion 130 coupled to the lower portion of the upper cushioning portion 120. ) may include. At this time, the graphene fabric 110, the upper cushioning portion 120, and the upper laminating adhesive portion 130 may be joined using an ultrasonic or high-frequency method.

The graphene fabric 110 may be manufactured by containing graphene carbon or coated or foamed graphene yarn and resin material. The graphene yarn includes a thermoplastic resin, carbon powder, and additives. For 100 parts by weight of the thermoplastic resin, 5 to 15 parts by weight of carbon powder and 1 to 3 parts by weight of additives may be mixed.

At this time, the thermoplastic resin may be at least one of polyethylene, polypropylene, polyester, polynylon, polyacrylic, and polyurethane, but is not limited thereto.

The carbon powder is added to reduce skin irritation and increase heat retention by imparting conductivity to the graphene yarn and discharging microelectricity. Graphene powder, black diamond powder, and graphite powder can be mixed. In this case, graphene powder, black diamond powder, and graphite powder can be mixed at a weight ratio of 1:0.2 to 0.5:0.1 to 0.3.

The graphene conducts electricity more than 100 times better than copper, has electron mobility more than 100 times faster than silicon, which is mainly used as a semiconductor, is more than 200 times stronger than steel, and is twice as strong as diamond, which is known to have the highest thermal conductivity. It has the above thermal conductivity, is transparent because it allows most light to pass through, and is known to have excellent elasticity.

In addition, the black diamond powder can be added to block electromagnetic waves, reduce skin irritation by absorbing microcurrents, and improve conductivity with graphene yarn.

The graphite powder is produced by collecting ore from the metamorphic rock layer, pulverizing it, polarizing it by size to obtain a high-purity pulverized product with a purity of 99% or more, and then acid-treating it. The carbon content is 99.9% or more and the particle size is about 0.1. It is ~10㎛.

This carbon powder has conductivity and has effects such as antibacterial, skin soothing, promoting blood circulation by far-infrared radiation, producing cell tissue, preventing aging, promoting metabolism, and preventing chronic fatigue and adult diseases. In particular, this effect is greatly manifested by graphene. When graphene is included alone, this effect has the advantage of being excellent. However, when the content of graphene is included in a high amount as described above, the fabric becomes excessively hard and the elongation rate decreases. Because of this problem, it is preferable to use black diamond powder and graphite powder together.

The graphene may have at least one particle shape among spherical, plate-shaped, needle-shaped, rod-shaped, and tube-shaped particles. Carbon powder has a high tendency to stack due to van der Waals attraction and easily forms aggregates, thereby preventing the formation of aggregates. Therefore, in order to improve the dispersion power of graphene within the graphene yarn, it is preferable to use spherical graphene.

The particle size of the carbon powder may range from 50 to 170 nm. If the particle size is less than 50 nm, the carbon powder is not uniformly distributed within the thermoplastic resin during the process of manufacturing the graphene yarn, and the carbon powder agglomerates with each other. This is because the physical properties of the graphene yarn are lowered by forming aggregates, and when the particle size of the graphene yarn exceeds 170 nm, there is a problem that the carbon powder cannot be stably attached to the graphene yarn and is easily detached. .

On the other hand, the graphene yarn may contain 5 to 15 parts by weight of carbon powder based on 100 parts by weight of the thermoplastic resin, but when the carbon powder is contained in less than 5 parts by weight, it is difficult to obtain the effect of removing microcurrents by graphene, If it exceeds 15 parts by weight, the elasticity, flexibility, and feel of the fabric may become poor, making it difficult to use as a mat, so it is preferable that it be within the above-mentioned weight range.

The conductive organic powder may be included in an amount of 2 to 5 parts by weight based on 100 parts by weight of the thermoplastic resin. If it is included in less than 2 parts by weight, the effect of improving the physical properties and conductivity of the yarn by the conductive organic powder is minimal, and 5 parts by weight is used. If it exceeds the content, the content of the thermoplastic resin is relatively reduced excessively and the physical properties of the graphene yarn deteriorate, so it is preferable that the weight be contained within the above-mentioned weight range.

As such a conductive organic powder, at least one selected from the group consisting of polyacetylene, polypyrrole, polythiophene, polyaniline, and polyacene may be used, and the particle size of the conductive organic powder is 50 to 170, similar to that of the carbon powder.

If it is contained in less than 1 part by weight, the effect of improving the physical properties by the additive is minimal. , if it exceeds 3 parts by weight, problems may arise in which the elongation, elasticity, strength, etc. of the yarn are reduced, and it is preferable that it be contained within the above-mentioned weight range. The additives may include, but are not limited to, anti-foaming agents, UV stabilizers, antistatic agents, etc.

The upper laminating adhesive portion 130 may be made of cotton for laminating adhesive.

The graphene fabric 110 may additionally contain red clay and natural product powder. The red clay and natural product powder may include 15 to 30 parts by weight of red clay and 30 to 50 parts by weight of natural product powder based on 100 parts by weight of thermoplastic resin.

The red clay is known to be effective in preventing aging of the human body by emitting far-infrared rays that are beneficial to the human body, activating the physiological functions of cells, generating heat energy, and activating metabolism and blood circulation. In addition, it is widely known for its beneficial effects of suppressing the growth of bacteria such as mold due to its excellent antibacterial properties and removing wastes due to its high adsorption properties. There is a large amount of calcium carbonate (CaCO3) in red clay, which has the property of not breaking easily and turning it into clay when water is added. In addition, red clay contains silica (SiO2), alumina (Al2O3), iron, magnesium, and sodium.

In addition, the natural product powder may be a variety of natural products. For example, it may include 20 to 30% by weight of mugwort powder, 20 to 30% by weight of aloe powder, 20 to 30% by weight of leaf powder, and 20 to 30% by weight of pine leaf powder. There you go. At this time, the mugwort is excellent for preventing aging and promoting skin regeneration, and has excellent antibacterial and disinfecting effects. The aloe is a fleshy perennial herb, the upper leaves are a medicinal material made from dried leaves of a mulberry tree of the Moraceae family or a related plant of the same genus, and the pine leaves are leaves of a pine tree, a plant in the pine family. The aloe, upper leaves, and pine leaves all have a soothing effect on the skin. there is.

In this case, the graphene carbon coated heating element 300 may include Not only is it excellent insulating, but it also has the advantage of improving the basic physical properties of the polymer resin itself by improving the strength and heat resistance that polyvinyl chloride resin lacks.

The plasticizer provides plasticity to the polymer resin, enabling mixing between different types of polymer resin and uniform mixing of the polymer resin with other components other than the polymer resin, and provides formability to the graphene carbon-coated heating element 300. It is used to mold into a desired shape, and may be included in an amount of 20 to 40 parts by weight based on 100 parts by weight of the polymer resin. If the content of the plasticizer is less than 20 parts by weight, it is difficult to obtain the above-mentioned effects, and if the content of the plasticizer exceeds 40 parts by weight, it is difficult to obtain the above-mentioned effect. In this case, the flowability of the polymer composition increases excessively, making molding difficult, or the particulate material settles, making it difficult to form uniform physical properties in the entire area of the graphene carbon-coated heating element 300, so it is included within the weight range described above. It is desirable to be

These plasticizers include at least one trimellitic acid selected from the group consisting of triethyl hexyl trimellitate, triisononyl trimellitate, and triisodecyl trimellitate. Plasticizers may be used. At this time, the trimellitic acid-based plasticizer does not contain phthalic acid-based or adipic acid-based substances that are subject to environmental regulations, and therefore has the advantages of being environmentally friendly, low volatility, oil resistance, and heat resistance, etc. More preferably, the plasticizer is triiso. Triisononyl Trimellitate may be used.

The stabilizer is added to prevent or suppress deterioration of the graphene carbon-coated heating element 300 due to heat when heat is generated by the conductor, and is preferably contained in an amount of 2 to 5 parts by weight based on 100 parts by weight of the polymer resin. If it is contained in less than 5 parts by weight, it is difficult to obtain sufficient resistance to heat, and if it exceeds 5 parts by weight, the content of the stabilizer is excessive and may actually lower the mechanical properties of the graphene carbon-coated heating element 300, so the above-mentioned It is preferable that it is included within the weight range.

Such stabilizers may include phosphorus-based heat stabilizers, metal fatty acid salt-based, lead-based, organotin-based, and zinc-based heat stabilizers. Preferably, a stabilizer in which a phosphorus-based heat stabilizer and a zinc-based heat stabilizer are mixed at a weight ratio of 1:3 to 5 may be used. In this case, the advantage of improving the heat resistance of the polymer resin is compared to using only one type of heat stabilizer. there is.

The filler is a component added to improve the physical strength of the graphene carbon-coated heating element 300, and may be included in an amount of 1 to 3 parts by weight based on 100 parts by weight of the polymer resin. If the content of the filler is less than 1 part by weight, the physical strength is reduced. The strength improvement effect is minimal, and if it exceeds 3 parts by weight, the physical strength is excellent, but the bending properties are reduced and the graphene carbon-coated heating element 300 may be damaged when bending occurs, so it should be included within the above-mentioned weight range. desirable. Additionally, the filler may be at least one inorganic filler selected from the group consisting of calcium carbonate, barium carbonate, magnesium carbonate, zinc carbonate, calcium sulfate, and barium sulfate.

The additive is added to improve the physical properties and workability of the graphene carbon-coated heating element 300, and may be included in an amount of 1 to 3 parts by weight based on 100 parts by weight of the polymer resin. If the additive content is less than 1 part by weight, It is difficult to obtain the effect of the additive, and if it exceeds 3 parts by weight, there is a risk that the mechanical properties or workability of the graphene carbon-coated heating element 300 may be reduced by the additive, so it should be included within the above-mentioned weight range. desirable. Flame retardants, polymer stabilizers, and adhesion improvers can be used as these additives.

The flame retardant may be at least one selected from the group consisting of halogen-based flame retardants, phosphorus-based flame retardants, nitrogen-based flame retardants, and inorganic flame retardants.

In addition, if the content of trehalose in the mixture used as an adhesion improver is outside the above range, the adhesion improvement effect may be reduced or problems such as deterioration of bending properties may occur, so it is recommended to use a mixture mixed in the above-mentioned weight ratio as an adhesion improver. It is desirable.

This adhesion improver may be included in the graphene carbon fiber 320 in an amount of 0.5 to 1.5 parts by weight based on 100 parts by weight of the polymer resin. If the content of the adhesion improver is less than 0.5 parts by weight, the effect of improving adhesion is minimal, and if it exceeds 1.5 parts by weight, the adhesion improvement effect is minimal. In this case, there is a problem that the physical properties such as strength and bending properties of the graphene carbon-coated heating wire 300 are deteriorated, so it is preferable that the weight is included within the above-mentioned weight range.

Meanwhile, the graphene carbon fiber 320 may additionally contain 1.5 to 2.5 parts by weight of carbon black based on 100 parts by weight of the polymer resin. This has the advantage of providing an additional heat dissipation effect due to the inclusion of carbon black. If the content of carbon black is outside the above range, the additional heat dissipation effect may be minimal or there is a risk of deteriorating the physical properties of the graphene carbon-coated heating element 300. Therefore, if carbon black is additionally included, the weight range is within the above-mentioned weight range. It is desirable to be included within.

At this time, in preparing the spinning solution, carbon powder may be mixed with the molten thermoplastic resin, stirred, and then conductive organic powder may be further mixed and stirred. In this case, the micro-current removal efficiency of the graphene yarn is improved and the elongation and elasticity of the yarn are maintained excellently. Specifically, carbon powder was mixed with the molten thermoplastic resin and stirred for 10 to 30 minutes at a stirring speed of 200 to 500 RPM, then additionally mixed with conductive organic powder and stirred for 10 to 30 minutes at the same stirring speed to produce a spinning solution. It can be manufactured. Meanwhile, when the carbon powder and the conductive organic powder are added at the same time, the particles clump together to form an aggregate, so it is preferable to mix the carbon powder and the conductive organic powder by adding them in stages.

In addition, when manufacturing the graphene fabric 110, beneficial effects on the human body, such as antibacterial and skin soothing efficiency, can be obtained by additionally mixing red clay and natural product powder with the thermoplastic resin.

In the step (S200) of manufacturing the lower mat 200, the anti-slip non-slip base or dot-processed anti-slip fabric 210, the lower buffer 220, and the lower laminating adhesive 230 are combined using an ultrasonic or high-frequency method. It is produced by doing so.

In the step (S300) of installing the graphene carbon-coated heating wire 300, the heating wire 310 is coated with graphene carbon fiber 320 to increase thermal conductivity.

In the step (S400) of combining the upper mat 100 and the lower mat 200, the upper mat 100 and the lower mat 200 are combined using a laminating method in a state in which the graphene carbon-coated heating wire 300 is installed. I do it.

In this way, by combining the upper mat 100 with the graphene fabric 110 made of graphene yarn and containing red clay and natural product powder and the upper laminating adhesive portion 130, blood circulation by far-infrared radiation is promoted and the skin can calm down.

In addition, the lower mat 200, which is a combination of the anti-slip fabric 210 and the lower laminating adhesive 230, is combined with the upper mat 100, and graphene is added between the upper mat 100 and the lower mat 200. Heat conduction efficiency and durability can be improved by installing the graphene carbon-coated heating wire 300 coated with carbon fiber 320.
