TECHNICAL FIELD The present invention relates to a conductive thermoplastic resin composition, a thermoplastic resin and a molded article comprising the same, and more particularly, to a conductive thermoplastic resin composition which is imparted with conductivity so that it can be used in electrostatic painting and the like, a thermoplastic resin and a molded article containing the same.
Generally, various colors are given to parts such as a vehicle or a bike. For example, a body assembled in an assembling line of a vehicle body is transferred to a paint line to perform a paint process with a desired color.
Such a coating treatment process involves complicated steps sequentially. However, if the coating process is classified roughly, it is divided into an intermediate process in which a coating is formed while applying paint to the inside and the outside of the vehicle body through a pretreatment and an electrodeposition process, Is coated with an electrostatic coating method, and a clear coating process is carried out to coat the coating after the top coat is fixed and the top coat is fixed. Thus, the painting of the vehicle body is completed.
The electrostatic coating system used in the above-mentioned top-down process is a method of applying a high electric voltage to a coating material by applying charge with the coating material in a spray state, and a corona discharge is generated in the discharge electrode, The paint is adhered to the paint and the paint becomes negative electricity, so that the paint is adsorbed on the paint having the positive electric potential to form the paint film.
Advantages of the electrostatic painting method based on the conventional organic solvent-based coating method include: 1) reduction of environmental pollution due to the organic solvent-free use; 2) reduction of the amount of coatings by coating by electrostatic method; and 3) And 4) the same coloring as the body color by the same painting method as the metal body.
In order to apply such an electrostatic coating method, the coating material must have conductivity, and in the case of a non-conductive part such as a plastic, a conductive primer treatment process is indispensably required to form a coating film. Such a conductive primer process is a process of forming a primer component on the surface to impart conductivity to the surface of the non-conductive material, and this requires additional raw materials and procedures, which is problematic in that the economic efficiency is lowered.
A problem to be solved by the present invention is to provide a conductive thermoplastic resin composition.
Another object of the present invention is to provide a conductive thermoplastic resin containing the composition.
Another object to be solved by the present invention is to provide a molded article comprising the composition.
According to an aspect of the present invention,
100 parts by weight of a rubber-reinforced styrene resin; And
0.1 to 10 parts by weight of carbon nanotubes,
Wherein the aspect ratio of the carbon nanotubes is 150 or more.
According to another aspect of the present invention,
A thermoplastic resin comprising the composition is provided.
According to another aspect of the present invention,
And a molded article comprising the thermoplastic resin composition.
In the present invention, carbon nanotubes having a high aspect ratio and a long length are introduced into a non-conductive thermoplastic resin composition to impart conductivity, thereby increasing the electrostatic coating efficiency. As a result, it is possible to eliminate the conductive primer process when forming a coating film on a molded article containing a thermoplastic resin obtained by employing the thermoplastic resin composition, thereby reducing material and process cost, reducing the amount of paint used and improving coating efficiency The loss of the paint can be reduced and the economic efficiency can be greatly improved.
BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
Hereinafter, the conductive thermoplastic resin composition according to the embodiment of the present invention will be described in more detail.
A conductive thermoplastic resin composition according to one aspect of the present invention comprises 100 parts by weight of a rubber-reinforced styrene resin; And 0.1 to 10 parts by weight of carbon nanotubes, wherein the carbon nanotubes have an aspect ratio of 150 or more.
The rubber-reinforced styrene-based resin used in the composition is a polymer in which a rubber-like polymer is dispersed in a particle form in a matrix made of an aromatic vinyl-based copolymer and is used for various molded articles because of its excellent physical properties such as impact resistance. Therefore, in order to apply the electrostatic coating process to such a molded product, it is necessary to impart conductivity to the composition.
According to one aspect of the present invention, carbon nanotubes are introduced into the composition to impart conductivity, and it is preferable to use carbon nanotubes having a high aspect ratio for imparting higher conductivity.
According to one aspect, the carbon nanotube used in the thermoplastic resin composition is a material in which carbon atoms arranged in a hexagonal shape form a tube, and has a diameter of about 1 to 100 nm. Carbon nanotubes have strong tensile strengths greater than about 100 times greater than steel because of the strong covalent bonds of carbon atoms, and are excellent in conductivity, flexibility and elasticity, and chemically stable.
Examples of such carbon nanotubes include single-walled carbon nanotubes (SWCNTs) composed of one layer and having a diameter of about 1 nm, double-walled carbon nanotubes composed of two layers and having a diameter of about 1.4 to 3 nm There is a multi-walled carbon nanotube (MWCNT) having a diameter of about 5 to 100 nm consisting of a plurality of layers of a double-walled carbon nanotube (DWCNT) Can be used without any particular limitation.
The carbon nanotubes may be classified into a bundle type or a non-bundle type depending on the type thereof. The bundle type carbon nanotube may be a bundle or a rope type in which a plurality of carbon nanotubes are arranged or intertwined in parallel Quot; "Non-bundle or entangled" means a form without any constant shape, such as a bundle or a rope.
According to one embodiment, the aspect ratio of the carbon nanotubes may be in the range of diameter to length, and may be more advantageous in terms of imparting conductivity in the range of about 150 or more.
According to one embodiment, the average diameter of the carbon nanotubes may be, for example, 1 nm to 50 nm.
According to one embodiment, the carbon nanotubes may have an average length of about 5 탆 or more. Carbon nanotubes having a length in this range are more advantageous in improving the conductivity of the thermoplastic resin composition.
According to one embodiment, the average length of the carbon nanotubes can be measured by a scanning electron microscope (SEM) or a transmission electron microscope (TEM) photograph. That is, after obtaining photographs of the powdered carbon nanotubes as a raw material through these measuring devices, they were analyzed through an image analyzer, for example, Scandium 5.1 (Olympus soft Imaging Solutions GmbH, Germany) Can be obtained.
Since the carbon nanotubes have a network structure in a matrix of a thermoplastic resin, carbon nanotubes having a high aspect ratio and a long length are more advantageous in the formation of such a network, and as a result, the frequency of contact between networks is reduced, The value is reduced, which contributes to the increase of the conductivity.
The carbon nanotubes used in the composition have a relatively high bulk density, which may be more advantageous for improving the conductivity of the thermoplastic resin composition. The bulk density of the carbon nanotubes may range from 80 to 250 kg / m 3 , for example 100 to 220 kg / m 3 .
As used herein, the term "bulk density" means the apparent density of the carbon nanotubes in the raw material state, and the weight of the carbon nanotubes can be expressed as a value divided by the volume.
According to one embodiment, the carbon nanotube may be used in an amount of 0.1 to 10 parts by weight, or 0.5 to 5 parts by weight, based on 100 parts by weight of the rubber-reinforced styrene resin. Within this range, sufficient conductivity can be obtained while maintaining the physical properties of the rubber-reinforced styrene resin.
The rubber-reinforced styrene-based resin used in the conductive thermoplastic resin composition is a polymer in which a rubber-like polymer is dispersed in the form of particles in a matrix made of an aromatic vinyl-based copolymer, and the aromatic vinyl-based monomer and the aromatic vinyl- And adding and polymerizing a vinyl monomer copolymerizable with the monomer.
Examples of such rubber-reinforced styrene resins include acrylonitrile-butadiene-styrene copolymer resin (ABS), acrylonitrile-acrylic rubber-styrene copolymer resin (AAS), acrylonitrile-ethylene propylene rubber- Resin (AES), and the like.
The rubber-reinforced styrene-based resin can be produced by a known polymerization method including emulsion polymerization, suspension polymerization and bulk polymerization, and there is no particular limitation. For example, a styrene-based graft copolymer resin alone or a mixture of a styrene-based graft copolymer resin and a styrene-based copolymer resin, followed by extrusion. The extrusion temperature is not limited, but may range, for example, from 200 to 300 占 폚. In the case of the bulk polymerization, the rubber-reinforced styrene resin can be prepared only by a one-step reaction process without separately preparing the styrene-based graft copolymer resin and the styrene-based copolymer resin. When a styrene-based graft resin and a styrene-based copolymer resin are used in combination, it is preferable to blend them in consideration of their compatibility.
The rubber content of the rubber-reinforced styrene-based resin may range from 5 to 30% by weight based on the weight of the whole resin.
The styrene-based graft copolymer resin in the rubber-reinforced styrene-based resin may be blended in an amount of about 5 to about 70 wt%, and the styrene-based copolymer resin may be blended in an amount of about 30 to 95 wt%. Preferably, a mixture of 10 to 50% by weight of a styrene-based graft copolymer resin and 50 to 90% by weight of a styrene-based copolymer resin can be extruded and used.
For example, when a mixture of the styrene-based graft copolymer resin (A) and the styrene-based copolymer resin (B) is extruded as the rubber-modified styrene resin, the weight ratio of A: B is 1: 1.5 to 1: 3 .
Hereinafter, the styrene-based graft copolymer resin (A) and the styrene-based copolymer resin (B) will be described in more detail.
(A) a styrene-based graft copolymer resin

Examples of the rubber-like polymer include diene rubbers such as polybutadiene, poly (styrene-butadiene) and poly (acrylonitrile-butadiene), and saturated rubbers in which hydrogen is added to the diene rubber, isoprene rubber, chloroprene rubber, And ethylene / propylene / diene monomer terpolymers (EPDM).
Such a rubber-like polymer may be contained in an amount of about 5 to about 65 wt% of the styrene-based graft copolymer resin. In consideration of the impact strength and appearance of the styrene-based graft copolymer, the rubber-like polymer may have a particle shape, and the particles may have an average diameter of, for example, 0.1 탆 to 4 탆.

(B) a styrenic copolymer resin
The styrene-based copolymer resin can be produced by polymerizing the above-mentioned aromatic vinyl-based monomer and a monomer copolymerizable with the aromatic vinyl-based monomer in the production of the graft copolymer.

These aromatic vinyl monomers may be contained in an amount of about 60 to 90% by weight of the styrenic copolymer resin.
Examples of the monomer copolymerizable with the aromatic vinyl-based monomer include saturated nitrile-based, unsaturated nitrile-based ones such as acrylonitrile and methacrylonitrile, and mixtures of two or more thereof. The copolymerizable monomer may be contained in an amount of about 10 to 40% by weight of the styrenic copolymer resin.
According to one embodiment, monomers such as acrylic acid, methacrylic acid, maleic anhydride, N-substituted maleimide and the like may be further added to the styrene-based copolymer resin in order to enhance the heat resistance. In an amount of about 15% by weight.
According to one embodiment, the styrenic copolymer resin may be required to have high flow characteristics for processability and the like. In this case, a low molecular weight styrenic copolymer may be used.
As the styrenic copolymer resin, the styrenic copolymer resin (C) having enhanced heat resistance characteristics and the styrenic copolymer resin (D) having enhanced flow characteristics may be mixed and used. It can be selected appropriately according to the application. For example, the content ratio of C may be increased in applications where heat resistance is more required, and the content ratio of D may be increased in applications where workability is more demanding. For example, the weight ratio of C: D is 0.1 to 0.9: 0.1 to 0.9.
According to one embodiment, the conductive thermoplastic resin composition is one selected from the group consisting of a flame retardant, a flame retardant aid, a lubricant, a plasticizer, a heat stabilizer, a dripping inhibitor, an antioxidant, a compatibilizer, a light stabilizer, a pigment, a dye, The content of the additive may be 0.1 to 10 parts by weight based on 100 parts by weight of the rubber-reinforced styrene resin. The specific types of these additives are well known in the art, and examples that can be used in the compositions of the present invention can be appropriately selected by those skilled in the art.
According to one aspect, the method for producing the thermoplastic resin composition is not particularly limited. However, the raw material mixture may be supplied to a commonly known melt mixer such as a single shaft or a biaxial extruder, a Banbury mixer, a kneader, , Or a method of kneading at a temperature of 200 to 400 ° C.
Also, the order of mixing the raw materials is not particularly limited, and the rubber-reinforced styrene resin, the carbon nanotubes described above and, if necessary, the additives may be blended in advance, A method of homogeneously melt-kneading with a twin-screw extruder, a method of removing the solvent after mixing in a solution, and the like are used. Of these, from the viewpoint of productivity, a method of homogeneously melt-kneading with a single-screw or twin-screw extruder is preferred. In particular, a method of uniformly melt-kneading at a melting point or higher of the thermoplastic resin using a twin screw extruder is preferably used.
Examples of the kneading method include a method of batchwise kneading components such as a rubber-reinforced styrene resin, a carbon nanotube, and an additive, a resin composition containing a rubber-reinforced styrene resin and carbon nanotubes and additives at a high concentration (Master pellet method) in which the carbon nanotubes and additives or a rubber-reinforced styrene resin are added and melted and kneaded so as to have a predetermined concentration, and any kneading method may be used . As another method, a rubber-reinforced styrenic resin and other necessary additives are injected from an extruder side and carbon nanotubes are fed to an extruder using a side feeder to suppress breakage of the carbon nanotubes, A method of producing a resin composition is preferably used.
