Description

TECHNICAL FIELD [0001] The present invention relates to a conductive glove and a method of manufacturing the conductive glove.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a conductive glove and a method of manufacturing the conductive glove, and more particularly, to a conductive glove provided with conductivity by a coating layer formed on a surface thereof.

Generally, the woven gloves function to protect the wearer's hands by wearing them, but they have a disadvantage in that they penetrate into the inside when liquid such as oil or water touches the wearer's gloves. .

[0003] Meanwhile, electronic devices equipped with touch panels are increasingly becoming more sophisticated and diversified in electronic products or electronic equipment in recent years. Those using the electronic device can input information to the electronic device by contacting the touch panel using another member such as a finger or a touch pen. The touch panel may be operated by, for example, a resistance pressure method, a capacitance method, an infrared method, or the like. In particular, smartphone users are increasing in number, and smartphones use capacitive systems with superior touch capabilities. The capacitive sensing method detects the change in capacitance caused when a conductive object touches a touch panel. When a user touches the touch panel of the capacitive type with a finger because the human body also conducts a minute current, the capacitance of the touched portion is changed, and this change is detected to detect that a specific input portion is touched.

As described above, the capacitive touch panel can operate when a conductive object or a person touches the touch panel. However, when the user touches the touch panel with general gloves, such as leather gloves, woven gloves made of textile fabrics, knitted gloves knitted with yarn, these gloves are nonconductive, and the touch panel does not work. Therefore, there is an inconvenience that it is necessary to remove the gloves when using the smartphone in winter. This inconvenience may occur not only in a smartphone but also in the case of using various electronic products having a touch panel. For example, for people with occupations that need to work with gloves, it may be inconvenient and labor-intensive to enter into an electronic product through the touch panel when unlocking the glove.

Therefore, the outer surface of the palm portion of the glove is wear resistant and can exhibit excellent frictional force, so that even when the rough work is performed, the user is not injured by the operator's hand while inputting any electronic product through the touch panel It is required to develop a product capable of performing the above-described process.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Also, when an element is referred to as " comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

Conductive glove

One aspect of the present invention includes a glove and a coating layer formed on at least a part of the surface of the glove, wherein the coating layer is made of a conductive resin composition comprising latex and water-dispersed carbon nanotubes, 1 to 10% by weight of carbon nanotubes, 1 to 10% by weight of a first surfactant, and a residual amount of water.

The latex may be one selected from the group consisting of nitrile rubber, acrylonitrile-butadiene rubber, styrene-butadiene rubber, butadiene rubber, natural rubber, water-dispersed polyurethane dispersion and a mixture of two or more thereof, May be acrylonitrile-butadiene rubber, but is not limited thereto.

Since the latex is prepared by adding not only monomers but also an emulsifier (surfactant) and an initiator to water to be a polymerization medium, the latex prepared after the emulsion polymerization contains rubber particles dispersed in water and a certain amount of emulsifier Active agent) may remain.

The water-dispersed carbon nanotube may include a carbon nanotube, a first surfactant, and a residual amount of water. Generally, the carbon nanotubes themselves are provided in a powder phase, and the powdered carbon nanotubes are not compatible with the latex because they are not compatible with the latex, so that the carbon nanotubes can not be uniformly mixed with the latex. Accordingly, the carbon nanotubes can be dispersed in water in the presence of the first surfactant, and the compatibility and dispersibility of the carbon nanotubes and the latex can be improved by mixing the water-dispersed carbon nanotubes with the latex. The first surfactant may be primarily bonded to the surface of the carbon nanotube to improve the dispersibility of the carbon nanotube in the water-dispersed carbon nanotube.

The conductive resin composition is produced by mixing latex and water-dispersed carbon nanotubes containing a certain amount of solid components, and the solid content contained in each of them is mixed through an aqueous medium, that is, water. However, since the solid content is essentially hydrophobic, the compatibility with the aqueous medium is low, and thus the dispersibility in the aqueous medium is low.

The latex may contain a certain amount of an emulsifier, that is, a second surfactant, wherein the first surfactant contained in the water-dispersed carbon nanotubes and the second surfactant contained in the latex have the same properties , It is possible to induce smooth compounding and uniform dispersion of the latex and the water-dispersed carbon nanotube when they are wet-compounded.

The first and second surfactants may be anionic surfactants, and the first and second surfactants may be the same.

For example, the anionic surfactant may be an alkyl benzene sulfonate, an alcohol sulfate, an alcohol ether sulfonate, an alkyl phenol ether sulfonate, an alpha olefin sulfonate, a paraffin sulfonate, an ester sulfosuccinate, a phosphate ester, Sulfonate, and a mixture of two or more thereof, preferably sodium dodecylbenzenesulfonate, but is not limited thereto.

If the content of the carbon nanotubes in the water-dispersed carbon nanotubes is less than 1% by weight, sufficient conductivity can not be imparted to the coating layer. If the content of carbon nanotubes exceeds 10% by weight, durability and moldability are deteriorated and the dispersibility of the carbon nanotubes The conductivity is not uniformly realized in each region of the coating layer, which is economically disadvantageous.

If the content of the first surfactant in the water-dispersed carbon nanotubes is less than 1 wt%, the dispersibility of the carbon nanotubes and compatibility with the latex may be deteriorated. If the content of the first surfactants is more than 10 wt%, the carbon nanotubes and the latex The relative content of the coating layer may be decreased and the conductivity and durability of the coating layer may be lowered.

The carbon nanotubes are materials for imparting electrical and thermal conductivity (hereinafter, referred to as 'conductivity') to latex and / or rubber, which are nonconductive materials, and the surface of the gloves is coated with a conductive resin composition obtained by kneading the carbon nanotubes So that the necessary conductivity can be imparted to the surface of the glove.

The carbon nanotubes can be classified into single wall carbon nanotubes, double wall carbon nanotubes, multi wall carbon nanotubes, truncated conical shapes, A cup-stacked carbon nanofiber in which a plurality of truncated graphene layers are stacked, and a mixture of two or more thereof, and preferably, But it is not limited thereto.

The multi-walled carbon nanotubes having an average outer diameter of 5 to 50 nm and an average inner diameter of 40% or more, and preferably 40 to 90% of the average outer diameter, or in the form of a bundle. The outer diameter refers to the diameter of the carbon nanotube cross section including the graphite layer constituting the wall of the carbon nanotube, and the inside diameter refers to the diameter of the hollow cross section excluding the graphite layer.

If the average diameter of the single-stranded carbon nanotubes is less than 8 nm or more than 50 nm, the average bundle diameter of the multi-walled carbon nanotubes formed by aggregation of them is not controlled within the range described below. It may be preferable to use carbon nanotubes having a large number of carbon nanotubes. As used herein, the term " bundle " refers to a bundle or rope shape in which a plurality of carbon nanotubes are arranged side by side or mutually entangled, and in contrast, a plurality of carbon nanotubes do not have a constant shape If present, it may be called "off-duty type".

The multi-walled carbon nanotube may basically exist as a plurality of carbon nanotubes, preferably, a plurality of multi-walled carbon nanotubes co-aggregated. Each carbon nanotube and its bundle may be in a linear, curvilinear, or mixed form.

If the average diameter of the single-walled carbon nanotubes, that is, the multi-walled carbon nanotubes is less than 40% of the average outer diameter, the internal volume of the carbon nanotubes may be decreased to decrease the conductivity. The inner diameter may be 40% or more of the average outer diameter.

The multicomponent carbon nanotubes may be obtained by mechanically and physically pressing a powdery material into a pellet shape. The multi-walled carbon nanotubes processed in the form of pellets can prevent scattering of the powder in the operation, thereby improving the working environment.

As used herein, the term " Raman spectroscopy " refers to a method of obtaining the frequency of a molecule in a Raman effect, which is a phenomenon in which scattered light having a frequency corresponding to a frequency of a molecule is generated when monochromatic excitation light such as laser light is irradiated Means that the crystallinity of carbon nanotubes can be quantified and measured by Raman spectroscopy.

The peak present in the wavenumber range 1580 ± 50 cm ^-1 in the Raman spectrum of the carbon nanotubes is referred to as a G band, which is a peak indicating the sp ² bond of carbon nanotubes, and represents a carbon crystal having no structural defect. Further, a peak present in the wavenumber range of 1360 ± 50 cm ^-1 is referred to as a D band, which is a peak indicating the sp ³ bond of carbon nanotubes, indicating carbon having a structural defect.

Further, the peak values of the G band and the D band are referred to as I _G and I _D , respectively, and the crystallinity of the carbon nanotubes can be quantified by measuring the Raman spectral intensity ratio (I _G / I _D ) have. That is, the higher the Raman spectroscopic intensity ratio, the less structural defects of the carbon nanotubes. Therefore, when the carbon nanotubes exhibiting a high Raman spectral intensity ratio are used, better conductivity can be realized.

Specifically, the Raman spectral intensity ratio (I _G / I _D ) of the carbon nanotubes may be 1.0 or more. If the _IG / I _D value of the carbon nanotubes is less than 1.0, amorphous carbon is contained in a large amount and the crystallinity of the carbon nanotubes is poor, so that the effect of improving the conductivity when mixed with the latex may be weak.

Since carbon nanotubes have a higher carbon content, they have less impurities such as catalysts and can exhibit excellent conductivity. Therefore, the carbon purity of the carbon nanotubes is 95% or more, preferably 95 to 98%, more preferably, 96.5 to 97.5%.

If the carbon purity of the carbon nanotubes is less than 95%, structural defects of the carbon nanotubes may be induced to deteriorate crystallinity, and the carbon nanotubes may be easily broken or broken by external stimuli.

The average diameter of the bundle-type carbon nanotubes formed by agglomerating the single-stranded carbon nanotubes in the form of bundles may be 1 to 10 μm, preferably 3 to 5 μm, more preferably 3.5 to 4.5 μm And the average bundle length may be 10 to 100 占 퐉, preferably 30 to 60 占 퐉, and more preferably 45 to 55 占 퐉.

The multicomponent carbon nanotubes can be dispersed in the conductive resin composition to form a three-dimensional network structure, and as the network structure is firmly formed, the conductivity can be improved. In particular, the network structure can be firmly formed by controlling the average bundle diameter and average bundle length of the bundle-type carbon nanotubes to a certain range.

If the average bundle diameter of the bundle-type carbon nanotubes is less than 1 占 퐉 or the average bundle length is more than 100 占 퐉, the dispersibility of the bundle-type carbon nanotubes may deteriorate and the conductivity of the coating layer in the conductive glove may be uneven, Or an average bundle length of less than 10 mu m, the network structure may become unstable and the conductivity may be lowered.

The higher the oxygen content in the bundle-type carbon nanotubes, the lower the conductivity, so that carbon nanotubes having a low oxygen content can be used. Specifically, the oxygen content of the multicomponent carbon nanotubes may be 0.5 wt% or less, preferably 0.1 to 0.5 wt%, based on the total weight of the multicomponent carbon nanotubes.

On the other hand, the content of the water-dispersed carbon nanotubes in the conductive resin composition may be 1 to 20 parts by volume, preferably 1 to 10 parts by volume, based on 100 parts by volume of the latex, and the conductive resin composition may contain the solid component For 100 parts of skin, the water-dispersed carbon nanotubes may contain 0.1-1.0 parts by mass of solids.

If the content of the water-dispersed carbon nanotubes is less than 1 part skin to 100 parts of latex skin, sufficient conductivity can not be imparted to the coating layer. If the amount of the water-dispersed carbon nanotube is more than 20 parts skin, the coating property and formability of the conductive resin composition may be lowered.

The water-dispersed carbon nanotube may include the carbon nanotube and the first surfactant at a weight ratio of 1: 0.5 to 1.5, respectively. If the ratio of the carbon nanotubes to the first surfactant is out of the above range, the dispersibility of the carbon nanotubes may be deteriorated, so that the conductivity of the coating layer in the conductive glove may be ununiform and the wear resistance may be deteriorated.

The conductive resin composition may further include a stabilizer such as KOH, a sulfur, a zinc oxide, a zinc diethyldithiocarbamate (EZ), a foam stabilizer, a coagulant, a foam stabilizer, and a thickener.

The stabilizer, for example, KOH may be diluted to a concentration of 10% by weight when the latex is nitrile rubber. When the latex is acrylonitrile-butadiene rubber, it may be diluted to a concentration of 5% by weight ≪ / RTI > concentration. The foam stabilizer can stabilize the latex and prevent the foam from breaking.

The coagulant may be used at a reaction temperature of about 55 to 80 ° C. The foam stabilizer, preferably silicone foam stabilizer, may be diluted to a concentration of 50% by weight.

The thickening agent may be an acrylate-based alkali-type thickener, preferably diluted to a concentration of 20% by weight.

The surface resistance of the coating layer may be 10 ³ to 10 ⁹ Ω / sq.

Method for manufacturing conductive gloves

According to another aspect of the present invention, there is provided a water-dispersed carbon nanotube comprising: (a) 1 to 10% by weight of carbon nanotubes; 1 to 10% by weight of a first surfactant; (b) mixing the water-dispersed carbon nanotubes, latex and additives to prepare a conductive resin composition; And (c) dipping at least a part of the glove on the conductive resin composition and drying the conductive glove.

The dispersing unit usable in the step (a) may be as follows.

The first type is a bead mill or a mixer using a direct grinding method. Bead mills, which are collectively referred to as milling media (grinding media), are mills, ball mills, attrition mills, vertical mills, It can be divided into disk type, pin type, high energy mill and paint shaker. Among them, a ball mill is a rotary mill using a ball-shaped grinding media, and an induction mill is a facility for performing grinding using the frictional force of the rollers. Examples of the mixer include a three-roll mill, a planetary mixer, and a paste mixer. As the direct grinding method, a wet method is widely used, but the present invention is not limited thereto.

The second type is a homogenizer. The homogenizer is a hydraulic type in which particles are passed through fine nozzles using a piston driven by a hydraulic pump and pulverized by a difference in pressure generated when the fine particles pass through the fine nozzles, And a rotary type in which particles are crushed and homogenized by using a high shear force generated in a rotor gap rotating by a centrifugal force. Preferably, a hydraulic homogenizer, more preferably a high pressure homogenizer, is used, but is not limited thereto.

The third type is an ultrasonic disperser. The ultrasonic dispersing device is a device using the sound pressure effect of ultrasonic waves and cavitation. As the frequency increases, high-energy cavities are created. During the formation of these cavities, particles can be pulverized and dispersed by the energy and shock waves generated by the formation and rupture of numerous microbubbles. That is, the vibration energy due to the formation and rupture of the bubbles acts as a force necessary for grinding and dispersing the particles.

Although three types of dispersing apparatuses are exemplified as the dispersing apparatuses used in the production of the carbon nanotube solution, at least one of the three dispersing apparatuses can be selected. Further, when two or more types are used together, any type of dispersing machine may be used first. For example, only a homogenizer may be used, but ultrasonic dispersers may be used together, and their posterior relationship may be reciprocal.

The step (b) may include mixing the latex and the water-dispersed carbon nanotube in the presence of a stabilizer such as KOH, sulfur, zinc oxide, Zinc Diethyldithiocarbamate (EZ), a foam stabilizer, a coagulant, , Wet mixing, or wet compounding. In order to achieve a required level of dispersibility of the carbon nanotubes in the conductive resin composition, the mixing may be performed for 2 hours or more, preferably 2 to 10 hours have. The types of the stabilizer, sulfur, zinc oxide, accelerator (EZ: Zinc Diethyldithiocarbamate), foam stabilizer, coagulant, foam stabilizer and thickener which are further used in the wet compounding and their action and effects are as described above.

The latex may further comprise a second surfactant, and the first and second surfactants may be anionic surfactants, and preferably the first and second surfactants may be the same.

The anionic surfactant may be, for example, an alkyl benzene sulfonate, an alcohol sulfate, an alcohol ether sulfonate, an alkyl phenol ether sulfonate, an alpha olefin sulfonate, a paraffin sulfonate, an ester sulfosuccinate, a phosphate ester, Benzene sulfonate, and mixtures of two or more thereof, preferably sodium dodecylbenzenesulfonate, but is not limited thereto.

In Production Examples 2-1 and 2-2, It can be seen that the carbon nanotubes not only impart conductivity to the portion of the glove coated with the conductive resin composition but also contribute to wear resistance. Further, in the case of Production Example 2-2 coated with a conductive resin composition containing a larger amount of carbon nanotubes than Production Example 2-1, the abrasion resistance was the most excellent.
