정전기를 방지하기 위한 대전방지제는 여러 종류가 있다. 일예로서 카본 블랙(Carbon black)을 이용하는 경우, 계면활성제(Surfactant)를 이용하는 경우, 금속염 화합물을 이용하는 경우 그리고 전도성 고분자를 이용하는 경우가 있다. 이중에서, 전도성 고분자는 양호한 도전성, 안정성 등의 장점을 지니고 있어서 각종 대전 방지제의 원료로서 활발히 이용되고 있다. 전도성 고분자는 단독으로 사용되는 경우, 용제로의 낮은 용해도, 강한 응집 현상 발생, 도전성의 부족 등의 현상으로 인하여 통상 도펀트(dopant)와 함께 이용된다. 대표적인 예로서 폴리(3,4-에틸렌디옥시티오펜, 이하 PEDOT이라 한다)이 있다. PEDOT은 폴리스티렌술폰산(Polystyrene sulfonic aicd, 이하 PSS라 한다)을 도펀트로 하여 수용성 또는 수분산성의 혼합체 형태로 이용된다. 상업화 되어 있는 PEDOT/PSS 착체로 Heraeus사의 Clevios, Agfa사의 Orgacon 등이 있다. 거의 모든 PEDOT/PSS 상업용 제품이 수분산 상태로 제공되며 PEDOT/PSS를 이용한 대전방지제는 수분산 폴리 우레탄과 같은 수계 원료를 활용하여 제조, 판매되고 있다. 그러나 수분산계 폴리 우레탄과 같은 원료는 그 본질적 한계로 인하여 높은 고형분을 유지하기 힘들고 코팅후 낮은 연필 경도, 낮은 자외선 안정성, 수분에의 취약성 등의 단점이 있다. There are several types of antistatic agents for preventing static electricity. As an example, carbon black may be used, surfactant may be used, metal salt compound may be used, and a conductive polymer may be used. Among them, conductive polymers have advantages such as good conductivity and stability and are actively used as raw materials for various antistatic agents. When used alone, the conductive polymer is usually used together with a dopant due to low solubility in solvents, strong coagulation, lack of conductivity, and the like. Representative examples include poly (3,4-ethylenedioxythiophene, hereinafter referred to as PEDOT). PEDOT is used in the form of a water-soluble or water-dispersible mixture using polystyrene sulfonic acid (hereinafter referred to as PSS) as a dopant. Commercialized PEDOT / PSS complexes include Hervios Clevios and Agfa Orgacon. Almost all PEDOT / PSS commercial products are supplied in a water-dispersible state, and antistatic agents using PEDOT / PSS are manufactured and sold using aquatic raw materials such as water-based polyurethanes. However, raw materials such as water-based polyurethanes are difficult to maintain high solids due to their inherent limitations, and have disadvantages such as low pencil hardness after coating, low UV stability, and susceptibility to moisture.
근래에는 수분산 PEDOT/PSS원료에 유기 용매를 혼합하고, 높은 안정성 및 경도를 보이는 유기 고분자를 바인더(binder)로 하는 혼합 코팅제가 많이 개발되고 있다. 이러한 재료는 통상 전도도의 한계로 인하여 대전방지제(Anti static)로 많이 활용되고 있다. 그러나 수분산계가 가지는 근본적인 한계, 즉 낮은 연필 경도, 낮은 안정성 등으로 인하여 응용 분야가 넓혀지지 못하고 있는 실정이다. In recent years, a mixed coating agent has been developed in which an organic solvent is mixed with a water-dispersed PEDOT / PSS raw material and an organic polymer showing high stability and hardness is used as a binder. Such materials are commonly used as antistatic agents due to the limitation of conductivity. However, due to fundamental limitations of the water dispersing system, that is, low pencil hardness and low stability, the application field is not expanded.

UV curable antistatic agent ", which must be accompanied by the solvent exchange process of PEDOT / PSS mixture prepared in the form of water dispersion, there is a high risk that the control of water content is not fully achieved and there is a disadvantage that it is not suitable for mass production .

According to patent document EP 1309646B1, a PEDOT / PSS mixture having a solid content of 15 to 20% of water content can be provided by freeze drying the PEDOT / PSS mixture synthesized as a water dispersion. Using this solid PEDOT / PSS mixture, a water free photocurable antistatic coating may be provided. However, in a specific embodiment, it is proposed to prepare a coating composition by dispersing the prepared solid PEDOT / PSS mixture again, and the manufacturing technology of the photocurable antistatic coating composition in which PEDOT / PSS is dispersed in an organic solvent is specifically described. It can not be presented.
특허 문헌 KR 10-1341049에 따르면, 특허 문헌 EP 1309646B1에서 제공되는 공정에 의해 제조된 고체 성상의 PEDOT/PSS 혼합체를 유기 용매에 재 분산하여 수분 함량이 최소화된 광경화형 대전 방지 코팅조성물의 제조 방법이 제공되고 있다. 고체 성상의 PEDOT/PSS 혼합체를 재분산함에 있어서 Dimethysulfoxide(DMSO), Ethyleneglycol(EG), Foramide(FA) 등과 같은 고비점 용매의 함량을 질량기준 90%이상 사용한다. 상기의 용매를 주된 분산 용매로 사용하는 경우, 독성 물질의 과량 사용에 따른 작업 환경의 부적절성의 문제 등이 발생할 수 있으며, 대전 방지 코팅 조성물의 원료로서 활용될 경우 고비점 용매의 높은 함량으로 인하여 코팅 공정의 제어가 어려울 수 있는 등의 문제가 있을 수 있다. 또한, DMSO, EG와 같은 용매의 경우 수분의 자연함량이 높은 특징이 있으므로 제어되지 않는 수분이 포함될 수 있다.According to patent document KR 10-1341049, a method for producing a photocurable antistatic coating composition having a minimum moisture content by redispersing a solid PEDOT / PSS mixture prepared by a process provided in patent document EP 1309646B1 in an organic solvent is disclosed.

집진통Dust collector
도 3은 본 발명의 일 실시예에 따른 집진통의 입체도를 개략적으로 도시한 도면이다. 도 4는 본 발명의 일 실시예에 따른 집진통의 단면도를 개략적으로 도시한 도면이다.3 is a view schematically showing a three-dimensional view of the dust collecting container according to an embodiment of the present invention. 4 is a schematic cross-sectional view of a dust collecting container according to an embodiment of the present invention.
일반적으로, "정전기"라 함은 마찰 전기등에서 나타나는 현상으로서 전하의 분포가 시간적으로 변화하지 않는 전하 및 그 전하에 의한 전기 현상을 말한다. 어떠한 물체들간에 대전이 이루어져 정전기가 발생하면, 상기 물체들이 정전 흡착력에 의하여 서로 달라붙는 현상이 나타난다.In general, the term "static electricity" refers to a charge occurring in a frictional electric lamp and the like, and an electric phenomenon caused by the charge whose charge distribution does not change in time. When static electricity is generated due to charging between certain objects, the objects may stick to each other by electrostatic attraction.
한편, 진공청소기 등에 사용되는 집진통의 내부에 먼지가 저장되는 경우, 상기 집진통 본체와 먼지간에 정전기가 발생하여 먼지가 상기 집진 본체에 달라붙어 잘 떨어지지 않게 된다. On the other hand, when dust is stored inside the dust collecting container used for the vacuum cleaner, etc., static electricity is generated between the dust collecting body and the dust, so that the dust does not stick to the dust collecting body so as not to fall off.
이 경우, 사용자가 먼지통을 털어내더라도, 상기 집진 본체(210)에 달라붙은 먼지가 잘 제거되지 않을 수 있다. In this case, even if the user shakes off the dust container, the dust stuck to the dust collecting body 210 may not be removed well.
그리고, 먼지를 비우기 위하여 집진통의 커버 부재를 여는 과정에서, 내부 먼지는 정전기적 반발력에 의하여 외부로 비산하며, 그에 따라 사용자가 먼지를 마시게 되어 비위생적인 환경이 조성되는 문제점이 발생될 수 있다. In addition, in the process of opening the cover member of the dust collecting container to empty the dust, the internal dust is scattered to the outside by the electrostatic repulsive force, the user may drink the dust, thereby creating a problem of creating an unsanitary environment. .
이러한 문제를 해결하기 위하여, 본 발명의 일 실시예에 따른 진공 청소기에 사용되는 집진통(100)은, 케이싱부(110), 및 상기 케이싱부의 내벽에 구비되는 코팅층(120)을 포함하고, 상기 코팅층(120)은, 폴리(3,4-에틸렌디옥시티오펜)-폴리스티렌술폰산(PEDOT/PSS) 0.1 내지 2.0 중량%, 분산보조제 1.05 내지 14 중량%,유기용매 60 내지 95 중량%, 경화성바인더 1 내지 40 중량%, 및 첨가제 0.01 내지 3 중량%를 포함한다.In order to solve this problem, the dust collecting container 100 used in the vacuum cleaner according to an embodiment of the present invention, the casing 110, and the coating layer 120 provided on the inner wall of the casing, The coating layer 120, poly (3,4-ethylenedioxythiophene)-polystyrene sulfonic acid (PEDOT / PSS) 0.1 to 2.0% by weight, dispersing aid 1.05 to 14% by weight, organic solvent 60 to 95% by weight, curable binder 1 To 40% by weight, and 0.01 to 3% by weight additive.
이와 같은 상기 코팅층(120)은 우수한 전도성을 부여하는 전도성 고분자를 포함하는 코팅층이고, 상기 전도성 고분자는 PEDOT/PSS 를 포함한다. 이와 같은 전도성 고분자는 상기 집진통(100)의 표면 저항을 낮추는 효과를 가진다. The coating layer 120 as described above is a coating layer containing a conductive polymer that provides excellent conductivity, and the conductive polymer includes PEDOT / PSS. Such a conductive polymer has an effect of lowering the surface resistance of the dust collector (100).
통상적으로 상기 집진통(100)의 케이싱부(110)은 합성수지, 예를 들어 Polycarbonate수지로 이루어질 수 있다. 상기 Polycarbonate 수지는 대략 1011~1015ohm/sqr의 높은 표면 저항을 가진다. 표면 저항이 높을 경우 상기 집진통(100)와 먼지간에 정전기가 발생될 가능성이 높아진다.Typically, the casing part 110 of the dust collecting container 100 may be made of a synthetic resin, for example, a polycarbonate resin. The polycarbonate resin has a high surface resistance of approximately 10 11 to 10 15 ohm / sqr. When the surface resistance is high, there is a high possibility of generating static electricity between the dust collecting container 100 and the dust.
그러나, 상기 전도성 고분자가 상기 집진통 (100)의 표면에 제공되면, 표면 저항이 낮아지고 전기 전도도가 상승하게 된다. 상기 전기 전도도가 상승하면, 상기 집진통(100)에 대전된 전하들은 청소기 본체측으로 이동되거나, 공기 중에 방전될 수 있다.However, if the conductive polymer is provided on the surface of the dust collecting container 100, the surface resistance is lowered and the electrical conductivity is increased. When the electrical conductivity is increased, the charges charged in the dust collecting container 100 may be moved to the cleaner body or discharged in the air.
따라서, 정전기가 상기 집진통 (100)에 생성되는 것이 방지되며, 이에 따라 먼지가 상기 집진통 (100)의 표면에 흡착되는 것이 방지될 수 있다. Therefore, static electricity can be prevented from being generated in the dust collecting container 100, and thus dust can be prevented from being adsorbed on the surface of the dust collecting container 100.
도 5은 본 발명의 일 실시예에 따른 집진통의 입체도를 개략적으로 도시한 도면이다. 도 6는 본 발명의 일 실시예에 따른 집진통의 단면도를 개략적으로 도시한 도면이다. 상기 도 3 및 도 4에 도시된 집진통에 관한 설명은 상기 도 5 및 도 6에 도시된 집진통에도 동일하게 적용될 수 있는 바, 이에 대한 설명은 생략하기로 한다, 도 5 및 도 6에서는 집진통(300)에 케이싱부(310) 및 코팅층(320)이 구비되어 있는 실시예가 도시되어 있다.5 is a view schematically showing a three-dimensional view of the dust collecting container according to an embodiment of the present invention. 6 is a schematic cross-sectional view of a dust collecting container according to an embodiment of the present invention. The description of the dust collector shown in FIGS. 3 and 4 may be equally applicable to the dust collector shown in FIGS. 5 and 6, and a description thereof will be omitted. An embodiment is shown in which the casing portion 310 and the coating layer 320 are provided in the pain relief 300.
본 발명의 일 실시예에 따른 분산액은 다양한 형태의 코팅 조성물에 활용되어 질 수 있으며, 표면 경도, 내후성, 내화학성, 내수성 등이 우수한 광경화형 코팅 조성물에 활용될 수 있는 효과를 발휘할 수 있다.Dispersion according to an embodiment of the present invention can be utilized in various types of coating composition, it can exhibit an effect that can be utilized in a photocurable coating composition excellent in surface hardness, weather resistance, chemical resistance, water resistance and the like.
