Description
본 발명은 열가소성수지를 기본수지로 하는 펠릿(Pellet)에 카본 블랙(carbon black)과 전도성 폴리머를 첨가하여 된 전기 전도성 복합수지 및 이를 이용한 시트(sheet)의 제조방법에 관한 것이다.The present invention relates to an electrically conductive composite resin obtained by adding carbon black and a conductive polymer to a pellet made of a thermoplastic resin, and a method of manufacturing a sheet using the same.
일반적으로 반도체의 조립, 운반과정 및 전산실, 실험실, 수술실 등 정전기 발생으로 피해를 볼 수 있는 작업장에서는 모든 주변환경들이 가능한한 최대로 정전기를 차단 또는 분산시킬 수 있는 도구를 이용하여 제품의 불량률을 방지하거나 첨단장비의 오작동을 미연에 방지할 수 있는 것이 주지의 사실이었다.In general, in the workshop where damage can be caused by static electricity generation such as semiconductor assembly, transportation process, computer room, laboratory, operating room, etc., all the surrounding environment is prevented by using tools that can block or disperse static electricity as much as possible. In addition, it was well known that malfunctions of high-tech equipment could be prevented beforehand.
최근 산업용 및 가전용 전자기기 산업에서는 정전기에 의해 발생하는 먼지오염과, ESD(Electro-Static Discharge) 방전에 의한 전자부품의 파열 또는 열화의 방지가 가능하도록 정전기를 감쇠시킬 수 있는 전기 전도성 복합수지의 개발에 노력하고 있다.Recently, in the industrial and consumer electronics industry, an electrically conductive composite resin capable of attenuating static electricity to prevent dust contamination and deterioration or degradation of electronic components caused by electrostatic discharge (ESD) discharge is used. We are working on development.
상술한 바와 같은 전기 전도성 복합수지의 개발분야는 반도체 패키징 공정완료 후, 소비자에게 전달되는 패키지에 대하여 기계적, 전기적 특성이 변화되지 않도록 외부의 충격으로부터 반도체 패키지를 보호하기 위한 케이스인 캐리어 테이프(Carrier Tape)를 그 예로 볼 수 있다. 이러한 캐리어 테이프는 시트(sheet) 상태에서 소정의 포켓이 형성되도록 성형되어 제조된 후, 상기 포켓에 전기적인 특성에 민감한 반도체 패키지가 담겨지기 때문에, 운반과정이나 보관 중에 캐리어 테이프의 표면에서 발생하는 미세한 정전기에 의해 전자부품의 파괴가 발생하게 된다.The development field of the electrically conductive composite resin as described above is a carrier tape which is a case for protecting the semiconductor package from external impact so that the mechanical and electrical properties of the package delivered to the consumer are not changed after completion of the semiconductor packaging process. ) Is an example. Since the carrier tape is molded and manufactured to form a predetermined pocket in a sheet state, since the semiconductor package sensitive to electrical properties is contained in the pocket, the carrier tape is minutely formed on the surface of the carrier tape during transportation or storage. The static electricity causes destruction of electronic components.
이에, 종래에는 정전기를 감쇠하거나 차폐하기 위한 신소재 개발에 따른 전기 전도성 복합수지가 제시되고 있는데, 미국특허 US4478903에 제시된 전기 전도성 복합수지는 폴리스티렌(Polystyrene) 계열수지, ABS(Acrylonitrile-Butadiene-Styrene)수지의 열가소성수지를 가지는 기본수지에 전기 전도성을 부여하는 카본블랙(carbon black), 퍼니스블랙(furnace black), 채널블랙(channel black)을 첨가하여 형성시켰다. 또한, 미국특허 US5707699에 제시된 전기 전도성 복합수지는 폴리페닐렌에테르(polyphenylene ether)계열 수지, 폴리스티렌(Polystyrene)계열 수지, ABS수지를 가지는 열가소성수지의 기본수지에 전기 전도성을 부여하는 카본블랙(carbon black)과, 올레핀(Olefin) 계열의 수지를 첨가하여 형성시켰다.Therefore, conventionally, an electrically conductive composite resin is proposed according to the development of a new material for attenuating or shielding static electricity, and the electrically conductive composite resin disclosed in US Pat. No. 4,447,893 is a polystyrene-based resin and an ABS (Acrylonitrile-Butadiene-Styrene) resin. It was formed by adding carbon black, furnace black, and channel black to impart electrical conductivity to the basic resin having a thermoplastic resin.

이하, 본 발명에 따른 전기 전도성 복합수지를 이용한 시트(sheet)의 제조방법을 바람직한 실시예로서 상세하게 설명하기로 한다.Hereinafter, a method of manufacturing a sheet using an electrically conductive composite resin according to the present invention will be described in detail as a preferred embodiment.
본 발명은 일반적인 수지 제조방법과 동일 유사한 것으로 각 원료탱크에 원료가 투입된 후, 제습건조기를 거쳐 수분을 제거하고, 자동 이송장치와 자동계량공급장치를 통해 반바리믹서 및 니더 내에 정밀계량 투입되어 반응 혼련하는 일련의 과정을 거치는 제조방법과 동일하되, 본 발명에서는 전도성 조성물과 혼합량만이 다르므로 이를 참고로 하여 설명하면 다음과 같다.The present invention is similar to the general resin manufacturing method, the raw material is added to each raw material tank, the moisture is removed through the dehumidifying dryer, and the precise weighing is added to the reaction device and the half-barrier mixer and the kneader through the automatic transfer device and automatic weighing device It is the same as the manufacturing method through a series of kneading process, but in the present invention, only the amount of the conductive composition and the mixing amount are different, which will be described with reference to the following.
먼저, 기본수지를 블렌딩(blending) 하는 단계로서, 가공성 및 물성이 우수한 열가소성수지 즉, SEBS(Styrene Ethylene Butylene Styrene)와, SBS(Styrene Butylene Styrene), SIS(Styrene Isoprene Styrene), 폴리파라메틸스티렌(Polyapramethylstyrene)을 포함하는 스티렌폴리머(Styrene polymer)계열의 수지 45∼75중량부, 그리고 폴리에틸렌(Polyethylen)과, 폴리프로필렌(Polypropylene)과, 디이엔고무(diene rubber)를 포함하는 폴리올레핀(Polyolefin)계열 수지 14∼33중량부, 또는 상술한 바와 같은 열가소성수지에 EPD(Erhylene-Propylene-Diene)와, EP(Erhylene-Propylene)와, 클로로플렌-고무(Choroprene-Rubber)와, 니트릴-부타디엔-고무(Nitrile-Butadiene Rubber)와, 스티렌-부타디엔-고무(Styrene-Butadiene Rubber)와, ECO(epichlorohydrin ethylene oxide)와, 실리콘(Silicon)과, 우레탄(Urethane)을 포함하는 열경화성수지 5∼10중량부를 블렌딩한다. 그 다음으로는, 상기와 같이 혼합된 기본수지에 고온 가공시 수지가 열산화되는 것을 억제하여 물성저하를 방지하기 위한 노화방지제 예컨데, 니켈-디부틸-디티오카바메이트(nickel-dibutyl-dithiocarbamate)와,벤조페논(benzophenone) 그리고, 벤조트리아졸(benzotriazole)을 포함하는 아민(Amine)계열 및 수지의 성형시 유동성이나 가공성을 증가시키기 위한 가공보조제 예컨데, 비이온성 올레오케미컬(oleochemical) 유도체나 지방산 금속 비누/아미드 0.05∼0.1중량부를 투입하여 반바리 믹서(Bunbary mixer) 및 니더(Kneader) 내에서 가압가열 및 반응혼련을 한 후, 트윈(twin) 압출기를 이용하여 컴파운드 펠릿(Pellet)을 형성한다.First, as a step of blending the basic resin, a thermoplastic resin having excellent processability and physical properties, that is, SBS (Styrene Ethylene Butylene Styrene), SBS (Styrene Butylene Styrene), SIS (Styrene Isoprene Styrene), polyparamethyl styrene ( 45 to 75 parts by weight of a styrenic polymer-based resin including polyapramethylstyrene, and a polyolefin-based resin including polyethylene, polypropylene, and diene rubber 14 to 33 parts by weight, or the above-mentioned thermoplastic resin, EPD (Erhylene-Propylene-Diene), EP (Erhylene-Propylene), Chloroprene-Rubber, Nitrile-Butadiene-Rubber (Nitrile) 5-10 parts by weight of a thermosetting resin including butadiene rubber, styrene-butadiene rubber, epichlorohydrin ethylene oxide (ECO), silicon (silicon), and urethane (urethane). Next, an anti-aging agent for preventing physical degradation by inhibiting the thermal oxidation of the resin during the high temperature processing to the mixed base resin as described above, for example, nickel-dibutyl-dithiocarbamate (nickel-dibutyl-dithiocarbamate) And, processing aids for increasing fluidity or processability during molding of amine series and resins containing benzophenone and benzotriazole, for example, nonionic oleochemical derivatives or fatty acids. 0.05 ~ 0.1 parts by weight of metal soap / amide is added to pressurized heating and reaction kneading in a Bunbary mixer and kneader, and then a compound pellet is formed using a twin extruder. .
다음으로, 상기의 컴퍼운드 펠릿에 전기 전도성을 부여하는 B.E.T 900이상의 카본블랙(carbon black)과, 전도성 폴리머를 투입하여 교반한 후, 컴파운드를 형성시키는데, 우선적으로 상기 펠릿에 카본블랙을 혼합한다. 그 후, 상기 카본블랙에 점착성을 부여하기 위한 점착성분 즉, 폴리우레탄(Polyurethane)계열이나, 클로로플렌고무(chloroprene rubber)계열 또는 에폭시수지를 2∼4중량부 첨가한다. 이와 함께, 점성 및 가공성을 향상시키기 위한 에스테르 오일(ester oil)과 방향족 오일(Aromatic oil)을 1∼3중량부 첨가한 후, 카본블랙 마스터 배치(master batch) 중량의 5∼70%를 차지하는 전도성 폴리머 예컨데, 폴리아닐린(Polyaniline)과, 폴리피롤(Polypyrrole)과, 폴리페닐렌(Polyphenylene) 중 어느 하나를 포함하는 전도성 폴리머를 첨가하여 고속교반시킴으로써 상기 펠릿에 카본블랙과 전도성 폴리머의 복합소재를 함침시킨다. 여기서, 카본블랙과 전도성 폴리머의 복합소재는 0.5∼20의 중량부를 가진다.Next, carbon black of B.E.T 900 or more that provides electrical conductivity to the compound pellet and a conductive polymer are added and stirred, and then a compound is formed, and the carbon black is first mixed with the pellet. Thereafter, 2 to 4 parts by weight of an adhesive component for imparting adhesion to the carbon black, that is, a polyurethane series, a chloroprene rubber series, or an epoxy resin is added. At the same time, after adding 1 to 3 parts by weight of ester oil and aromatic oil to improve viscosity and processability, the conductive material occupies 5 to 70% of the carbon black master batch weight. Polymer For example, a composite material of carbon black and a conductive polymer is impregnated into the pellet by high speed stirring by adding a conductive polymer including any one of polyaniline, polypyrrole, and polyphenylene. Here, the composite material of carbon black and the conductive polymer has a weight portion of 0.5 to 20 parts by weight.
다음으로, 트윈(twin) 압출기를 이용하여 반응과 혼련을 재실시하면, 전도성 복합수지의 컴파운드 펠릿을 얻게 된다.Next, when the reaction and kneading are carried out again using a twin extruder, a compound pellet of the conductive composite resin is obtained.
한편, 이와 같이 기본수지의 제조공정과, 후속공정의 일련공정에서 반응 및 혼련과정을 각각 1,2차로 나누어 수행하는 이유는 기본수지와 전도성 복합소재와의 상용성을 향상시키면서 전도성 고분자의 성능을 극대화하고, 카본블랙 구조의 파괴를 최소화하여 상기 기본수지에 고루 분포되게 함으로써, 도전체로서의 효과를 충분히 발휘시키기 위한 것이다. 아울러 상기와 같은 배합공정은 수지의 전기적 특성, 표면 평활성 그리고 분산성을 향상시키기 위함이다.On the other hand, the reason why the reaction and kneading process is divided into 1 and 2 in the manufacturing process of the basic resin and the subsequent process in the subsequent process is to improve the performance of the conductive polymer while improving the compatibility between the basic resin and the conductive composite material. Maximizing and minimizing the destruction of the carbon black structure to be evenly distributed in the base resin, to fully exhibit the effect as a conductor. In addition, such a compounding process is to improve the electrical properties, surface smoothness and dispersibility of the resin.
마지막으로는, 상기와 같은 컴파운드의 펠릿을 압출성형하여 시트(sheet)를 형성하는 단계로서, 도 1에 도시된 바와 같이, 컴파운드된 상기 펠릿을 압출기의 인입부(10)에 넣는다. 이러한 수지는 각각 세 경로로 분기된 압출경로(20a)(20b)를 따라 진행되면서 통상적인 티-다이(T-die; 미도시)로 보내진 후, 단층 또는 다층의 시트로 압출성형되어 외부로 인출된다. 상기 시트는 이러한 경로를 지나면서 0.2∼3.0㎜의 두께와, ±0.02%의 두께편차를 가지게 된다.Finally, as a step of forming a sheet by extruding the pellets of the compound as described above, as shown in Figure 1, the compounded pellets into the inlet 10 of the extruder. These resins are each sent along a three-way branched extrusion path 20a, 20b and sent to a conventional T-die (not shown), and then extruded into a single layer or a multilayer sheet and drawn out. do. The sheet has a thickness of 0.2-3.0 mm and a thickness deviation of ± 0.02% as it passes through this path.
이로써, 상기와 같은 방법에 의해 제조되는 시트는 103∼1010Ω/Sq의 표면저항을 가지며, 1∼15의 멜트플로우인덱스(melt flow index)를 가진다.As a result, the sheet produced by the above method has a surface resistance of 10 3 to 10 10 Pa / Sq and a melt flow index of 1 to 15.
이하, 본 발명의 실시예에 따라 상기 기본수지에 카본블랙과 전도성폴리머를 3∼5 중량부 만큼 첨가한 시트와, 상기 중량부의 카본블랙 만을 첨가하여 된 시트의 비교예를 비교 설명하면 다음과 같다.Hereinafter, a comparative example of a sheet obtained by adding 3 parts by weight to 5 parts by weight of carbon black and a conductive polymer to the base resin and a sheet obtained by adding only parts by weight of carbon black will be described. .
도 2를 참조하면, 본 발명의 실시예에 따른 시트의 표면상태는 각 중량부에서 양호한 상태를 보이나, 비교예에서와 같이 카본블랙만을 상기와 같이 동일한 중량부 만큼을 첨가하여 된 시트는 5중량부에서 불량한 것으로 나타났다. 이것은 기본수지에 카본블랙과 전도성 폴리머를 첨가할 경우, 상기 불량을 극복하기 위해 5중량부 이상의 카본블랙을 첨가해야 했던 종래와는 달리, 카본블랙의 사용감소로 인해 전도성 조성물의 분산성이 향상되어 압출가공 후 형성된 시트 표면의 평활성과, 표면에 요철 및 보이드(void)가 형성되지 않는다는 것을 의미한다. 그리고, 표면저항의 측면에서 볼 때, 본 발명의 실시예에 따른 시트의 표면저항은 비교예에 비해 다소 감소되었다는 것을 알 수 있다. 즉, 표면저항의 감소로 인한 전도성의 증가로 시트의 표면에서 발생하는 정전기를 용이하게 감쇠 분산시킬 수 있게 된다. 한편, 멜트플로우인덱스는 비교예에 비해 증가된 반면 경도는 감소한 것을 알 수 있다. 여기서, 상기 멜트플로우인덱스(melt flow index)는 200℃의 온도에서 수지 5㎏이 로딩되었을 때의 치수를 나타낸다. 이러한 멜트플로우인덱스와 경도를 비교해 볼 때, 카본블랙을 첨가하여 된 비교예 보다 카본블랙과 전도성폴리머의 조성물을 첨가한 실시예의 수지가 성형시 유동성이나 가공성이 양호하다는 인지할 수 있다. 즉, 복합수지의 물리적 기계적 특성을 증가시켜 시트 가공상의 약점인 유연성,용해성 및 성형성 등의 취약점을 개선할 수 있다.Referring to Figure 2, the surface state of the sheet according to an embodiment of the present invention shows a good state at each weight part, but as in the comparative example, the sheet made by adding the same weight parts as described above only carbon black as 5 parts by weight It appeared to be poor in wealth. This is because when carbon black and the conductive polymer are added to the base resin, in contrast to the prior art in which at least 5 parts by weight of carbon black had to be added to overcome the defect, the dispersibility of the conductive composition is improved due to the reduced use of carbon black. This means that the smoothness of the surface of the sheet formed after the extrusion process and no irregularities and voids are formed on the surface. And, in view of the surface resistance, it can be seen that the surface resistance of the sheet according to the embodiment of the present invention is somewhat reduced compared to the comparative example. That is, due to the increase in conductivity due to the decrease in surface resistance, the static electricity generated on the surface of the sheet can be easily attenuated and dispersed. On the other hand, it can be seen that the melt flow index is increased compared to the comparative example while the hardness is reduced. Here, the melt flow index represents a dimension when 5 kg of resin is loaded at a temperature of 200 ° C. When comparing the melt flow index and the hardness, it can be appreciated that the resin of the example in which the composition of the carbon black and the conductive polymer is added is better than the comparative example in which the carbon black is added. In other words, by increasing the physical and mechanical properties of the composite resin it is possible to improve the weakness of the sheet processing, such as flexibility, solubility and moldability.
이와 함께, 본 발명의 시트는 사출성형과 같은 연속 생산방식을 채택하여 작업성을 증대할 수 있을 뿐만 아니라, 쓰고 버리는 제품의 폐기시에도 재활용을 할 수 있으므로 환경오염을 줄일 수 있으며, 원자재를 수입하지 않아도되므로 저렴한 단가로 제품을 공급할 수 있는 매우 유용한 것이다.In addition, the sheet of the present invention adopts a continuous production method such as injection molding not only can increase workability, but also can be recycled at the time of disposal of used and discarded products, thereby reducing environmental pollution and importing raw materials. It is very useful to supply the product at a low price since it is not necessary.
이상에서의 설명에서와 같이, 본 발명에 따른 전기 전도성 복합수지 및 이를 이용한 시트(sheet)의 제조방법은 열가소성수지를 기본수지로 하는 펠릿(Pellet)에 카본블랙(carbone black)과 전도성 폴리머를 첨가하여 제조함으로써, 카본블랙의 함유량을 줄여 수지의 분산성 및 도전성을 향상시킬 뿐만 아니라, 열적안정성과 작업안정성 특히 물리적 기계적 특성이 향상되는 점에 그 장점이 있다.As described above, the electrically conductive composite resin according to the present invention and a method for producing a sheet using the same include adding carbon black and a conductive polymer to pellets made of thermoplastic resin. In this case, the carbon black has a merit of reducing the content of carbon black to improve the dispersibility and conductivity of the resin, as well as improving thermal stability and work stability, in particular physical and mechanical properties.
