Description
본 발명은 대전방지용 코팅조성물 및 대전방지용 코팅조성물이 도포된 대전방지 및 수분 차폐봉투에 관한 것으로 보다 상세하게는 전도성 고분자, 바인더 및 용매가 포함된 대전방지용 코팅조성물 및 이러한 코팅조성물이 도포된 대전방지 및 수분 차폐봉투에 관한 것이다.The present invention relates to an antistatic and moisture shielding bag coated with an antistatic coating composition and an antistatic coating composition, and more particularly, to an antistatic coating composition containing a conductive polymer, a binder, and a solvent, and an antistatic agent coated with the coating composition. And a moisture shielding bag.
컴퓨터 하드디스크드라이브용 헤드와 같은 정밀전자부품은 먼지 또는 주변의 습기에 의해 성능이 크게 좌우되므로 먼지 및 습기와 완전히 차단되어 수분의 영향을 받지 않는 상태에서 운반되어야 한다. 이때 이들 전자부품을 일정 용기에 담은 후 이를 다시 대전방지 또는 수분차폐 봉투에 넣고 진공포장하여 운반한다.Precision electronic components, such as heads for computer hard disk drives, depend heavily on dust or ambient moisture, and must be transported in a state that is completely isolated from dust and moisture and not affected by moisture. At this time, these electronic components are put in a container, and then put in an antistatic or moisture shielding bag and vacuum-packed.
이외에도 정밀 전자부품을 운반할 때는 대전방지 처리된 비닐, 보통의 경우 폴리에틸렌으로 만들어진 봉투에 담아 운반한다. 비슷한 목적으로 사용되는 봉투로는 알루미늄이 증착된 폴레에스터 필름을 폴리에틸렌 필름과 합지한 후 내외부 표면에 대전방지 처리하여 사용하는데, 알루미늄 증착층의 두께에 따라 또는 알루미늄이 증착된 폴리에스터 필름을 몇 겹, 예를 들어 한 겹 또는 두 겹 이상, 사용하느냐에 따라 수분차폐성능이 좌우된다.In addition, the precision electronic components are transported in bags made of antistatic vinyl, usually polyethylene. Envelopes used for similar purposes include aluminum-deposited polyester films laminated with polyethylene films and antistatic treatment on the inner and outer surfaces, depending on the thickness of the aluminum deposition layer or a few layers of aluminum-deposited polyester films. For example, one or two or more layers, depending on whether you use the moisture shielding performance depends.
각종 대전방지 차폐봉투는 일반적으로 알루미늄, 니켈, 티타늄, 구리, 크롬, 아연 등의 금속을 증착하거나 스퍼터링하여 제조된 금속증착 폴리에스터 필름과 저밀도 폴리에틸렌(low density polyethylene, LDPE), 선형저밀도 폴리에틸렌(linear low density polyethylene. LLDPE), 고밀도 폴리에틸렌(high density polyethylene, HDPE) 또는 이들 폴리에틸렌의 혼합물로 이루어진 폴리에틸렌 필름을 합지한 후 내외부 표면에 대전처리한 후 이 필름원단을 이용하여 봉투를 제조하여 사용한다.Various antistatic shielding bags are generally metal-deposited polyester films, low density polyethylene (LDPE), linear low density polyethylene (linear) made by depositing or sputtering metals such as aluminum, nickel, titanium, copper, chromium and zinc. A polyethylene film made of low density polyethylene (LDLPE), high density polyethylene (HDPE), or a mixture of these polyethylenes is laminated, and then subjected to an electrification treatment on the inner and outer surfaces thereof.
금속이 증착된 증착층의 두께에 따라 쉴딩백(shielding bag)과 수분차폐봉투(moisture barrier bag)용 원단으로 구분된다. 쉴딩백의 경우 광학밀도(optical density)가 0.6 정도인 알루미늄 증착 폴리에스터 필름을 주로 사용하고 있고, 수분차폐봉투의 경우에는 광학밀도가 2 정도인 알루미늄 증착 폴리에스터 필름을 2겹 또는 그 이상 합지한 후 폴리에틸렌 필름과 다시 합지하거나 또는 폴리에스터 필름과 각종 두께의 알루미늄 호일을 합지한 후 이를 다시 폴리에틸렌과 합지하여 사용한다.According to the thickness of the deposited layer on which the metal is deposited, it is divided into a shielding bag and a fabric for a moisture barrier bag. For shielding bags, aluminum-deposited polyester film with optical density of about 0.6 is mainly used, and in case of water-sealed bags, after laminating two or more layers of aluminum-deposited polyester film with optical density of about 2 It is laminated with polyethylene film or laminated with polyester film and aluminum foil of various thicknesses, and then it is used by laminating with polyethylene again.
각종 대전방지 차폐봉투 제조시 가장 중요한 문제는 내외층의 대전방지 처리기술이다. 종래에 플라스틱 표면에 대전방지 처리를 하기 위해서는 플라스틱에 전도성 카본블랙, 카본화이버 또는 계면활성제 등을 혼합하거나 또는 표면에 코팅하는 방법을 주로 이용한다.The most important problem in manufacturing various antistatic shielding bags is the antistatic treatment technology of the inner and outer layers. Conventionally, in order to perform an antistatic treatment on the surface of the plastic, a method of mixing conductive carbon black, carbon fiber or surfactant with the plastic, or coating the surface is mainly used.
그러나 이들 방법에 의해 제조된 대전방지 또는 수분차폐봉투는 근본적으로 큰 문제점을 안고 있다. 전도성 증진제로서 카본블랙을 사용할 경우에는 봉투가 완전히 검은색이 되어 내용물 확인이 불가능하며, 또한 카본블랙이 검은색 불순물이 되어 제품의 성능에 악영향을 미친다.However, the antistatic or moisture shielding bags produced by these methods have a major problem. When carbon black is used as a conductivity enhancer, the envelope becomes completely black and the contents cannot be checked. Also, carbon black becomes a black impurity, which adversely affects the performance of the product.
계면활성제를 사용하면 계면활성제가 주위의 수분과 반응하여 이온전도성을 띠는 물질이기 때문에 수분의존성이 심하며, 3-6개월 정도 시간이 지나면 대전방지성을 완전히 잃어버리고, 가장 중요한 것은 계면활성제가 봉투 표면으로 기어나오는 소위 이행성 때문에 제품 표면에 불순물이 석출되는 불량을 초래하는 단점이 있다. 또한 계면활성제를 사용할 경우 내용제성이 열악하여 계면활성제가 혼합되거나 코팅된 대전방지 봉투의 경우 물, 에틸알콜, 이소프로필알콜 등의 용제로 세척하면 대전방지성을 잃는 문제점이 있다.If surfactant is used, the surfactant reacts with the water around it, which is ionic conductivity, so it is highly dependent on water, and after 3-6 months, the antistatic property is completely lost. Because of the so-called transitionability that crawls out to the surface, there is a disadvantage of causing a defect that precipitates impurities on the surface of the product. In addition, when the surfactant is used, the solvent resistance is poor, and in the case of the antistatic envelope in which the surfactant is mixed or coated, there is a problem in that the antistatic property is lost when washing with a solvent such as water, ethyl alcohol, and isopropyl alcohol.
본 발명은 대전방지 차폐봉투 및 수분차폐봉투 등 각종 대전방지 차폐봉투 내외부 표면에 전도성 고분자로 이루어진 도전성 코팅액을 도포하여 표면저항이 102-1010Ω/□ 범위에서 조절이 가능하면서 도전성분의 이행이 없이 영구대전이 가능한 각종 대전방지용 코팅조성물 및 대전방지용 코팅코팅조성물이 도포된 대전방지 및 수분 차폐봉투를 제공하는 것을 목적으로 한다.The present invention is applied to the conductive coating liquid made of a conductive polymer on the inner and outer surfaces of the antistatic shielding bag and moisture shielding bag, such as an antistatic shielding bag and the surface resistance can be adjusted in the range of 10 2 -10 10 Ω / □ It is an object of the present invention to provide an antistatic and moisture shielding bag coated with various antistatic coating compositions and antistatic coating compositions capable of permanent charging.
본 발명의 대전방지용 코팅조성물은 전도성 고분자 0.5∼5 중량부, 바인더 10∼50 중량부, 용매 40∼85 중량부 포함하는 것을 특징으로 한다.The antistatic coating composition of the present invention is characterized in that it comprises 0.5 to 5 parts by weight of the conductive polymer, 10 to 50 parts by weight of the binder, 40 to 85 parts by weight of the solvent.
상기에서, 전도성 고분자는 폴리아닐린, 폴리티오펜, 폴리피롤 중에서 선택된 1종류 이거나 또는 이들로부터 변성된 변성 전도성 고분자를 사용할 수 있는데, 예를 들면 술포닐기로 치환된 폴리아닐린, 탄소수가 4-10인 알킬기가 치환된 폴리티오펜, 에틸렌디옥시기가 치환된 폴리티오펜, 옥타데실, 비페닐기가 치환된 폴리피롤 등의 변성 전도성 고분자를 사용할 수 있다.In the above, the conductive polymer may be one selected from polyaniline, polythiophene, polypyrrole, or a modified conductive polymer modified therefrom. For example, a polyaniline substituted with a sulfonyl group and an alkyl group having 4-10 carbon atoms may be substituted. Modified conductive polymers such as polythiophene, polythiophene substituted with ethylenedioxy group, octadecyl, and polypyrrole substituted with biphenyl group.
바인더는 카보닐기, 수산기, 에스터기, 아크릴기, 우레탄기, 카복실기, 아미드기, 이미드기 카복실산, 말레인산, 무수말레인산 중에서 선택된 1종류 또는 2종류 이상의 관능기가 포함되어 있는 수지를 사용한다.As the binder, a resin containing one or two or more functional groups selected from a carbonyl group, a hydroxyl group, an ester group, an acryl group, a urethane group, a carboxyl group, an amide group, an imide group carboxylic acid, maleic acid and maleic anhydride is used.
용매는 메타크레졸, 클로로포름, 이미다졸, 에틸알콜, 증류수, 이소프로필알콜, 노말부탄올, 메탄올 중에서 선택된 1종류를 사용하거나 또는 상기 용매 2종류가 5:95∼95:5의 비로 혼합된 혼합용매를 사용할 수 있다.The solvent may be one selected from methacresol, chloroform, imidazole, ethyl alcohol, distilled water, isopropyl alcohol, normal butanol and methanol, or a mixed solvent in which two solvents are mixed at a ratio of 5:95 to 95: 5. Can be used.
한편 전도성 코팅액을 대전방지용 필름원단에 코팅하는 방법은 상기에서 언급한 전도성 고분자 0.5∼5 중량부, 바인더 10∼50 중량부, 용매 40∼85 중량부를 포함하는 전도성 코팅액을 필름원단의 내외면에 직접 스프레이 하는 코팅법, 필름원단을 전도성 코팅액에 함침하는 방법 또는 그라비아 코팅법으로 필름원단의 내외면에 0.1∼2 미크론(㎛)의 두께로 코팅한 후 40∼110℃의 온도에서 1∼20분 동안 건조한다. 건조 후 전도성 코팅액 중의 용매가 휘발되면서 필름원단에 전도성 코팅막이 형성되는 것이다. 또한 원하는 색상이 있는 경우 원하는 색상을 나타낼 수 있는 안료를 전도성 코팅액에 혼합하여 전도성 코팅액을 필름원단 내외면에 코팅하거나 또는 필름원단에 미리 안료를 코팅한 후 전도성 코팅액을 상기의 방법에 의해서 필름원단에 코팅할 수 있다.On the other hand, the method of coating the conductive coating liquid on the antistatic film fabric is a conductive coating liquid containing 0.5 to 5 parts by weight of the conductive polymer, 10 to 50 parts by weight of the binder, and 40 to 85 parts by weight of the solvent directly on the inner and outer surfaces of the film fabric. Spray coating method, impregnating film fabric into conductive coating solution, or gravure coating to coat the inner and outer surfaces of film fabric with a thickness of 0.1 to 2 microns (µm) and then for 1 to 20 minutes at a temperature of 40 to 110 ° C. To dry. After drying, the solvent in the conductive coating solution is volatilized to form a conductive coating film on the film fabric. In addition, if there is a desired color, a pigment that can exhibit a desired color is mixed with the conductive coating solution to coat the conductive coating solution on the inner and outer surfaces of the film fabric or the coating film in advance in the film fabric, and then the conductive coating solution is applied to the film fabric by the above method. Can be coated.
한편 상기에서 언급한 스프레이, 함침 또는 그라비아 코팅 방법으로 필름원단 표면에 전도성 코팅액을 도포하기 전 프라이머 처리로서 카보닐기, 수산기, 에스터기, 아크릴기, 우레탄기, 카복실기, 카복실산, 아미드기, 이미드기, 말레인산, 무수말레인산 중에서 선택된 1종류 또는 2종류 이상의 관능기가 포함되어 있는 수지의 바인더를 단독 또는 2 종류 이상 혼합하여 필름원단 표면에 코팅한 후 40∼110℃의 온도에서 1∼20분 동안 건조한 후 전도성 고분자가 용매에 용해된 전도성 고분자액을 필름원단에 도포해도 동일한 효과를 얻을 수 있다.Meanwhile, carbonyl, hydroxyl, ester, acrylic, urethane, carboxyl, carboxylic acid, amide, and imide groups may be used as a primer treatment before applying the conductive coating solution to the surface of the film by the above-mentioned spray, impregnation, or gravure coating method. After mixing one or two or more kinds of binders of resins containing one or two or more functional groups selected from maleic acid and maleic anhydride, coating them on the surface of the film fabric and drying for 1 to 20 minutes at a temperature of 40 to 110 ° C. The same effect can be obtained even if the conductive polymer solution in which the conductive polymer is dissolved in a solvent is applied to the film fabric.
그리고 전도성 코팅액을 필름원단에 코팅한 후 전도층 코팅막을 경화시킬 필요가 있는 경우 경화제로 멜라민, 이소시아네이트를 바인더에 혼합하여 전도층을 경화시킬 수 있는데 경화제의 함량은 경화정도 및 경화시간 등에 따라 다르기는 하지만 일반적으로 바인더 함량에 대하여 0.1∼5 중량부를 사용한다. 경화제 함량이 바인더 함량에 대하여 0.1 중량부 미만 사용하는 경우 경화효과가 미미하고, 5 중량부 초과 사용해도 경화도 증가효과가 미미하기 때문에 원가절감 측면에서 바람직하지 않다.If the conductive coating liquid is coated on the film fabric and then the conductive layer coating film needs to be cured, melamine and isocyanate may be mixed with a binder to cure the conductive layer. The content of the curing agent may vary depending on the degree of curing and curing time. Generally, however, 0.1 to 5 parts by weight of the binder is used. When the content of the curing agent is less than 0.1 parts by weight relative to the binder content, the curing effect is insignificant, and even when used in excess of 5 parts by weight, the effect of increasing the degree of curing is insignificant.
현재 많이 사용하고 있는 각종 대전방지 제품 중 대전방지 차폐봉투는 주로 알루미늄으로 증착된 폴리에스터 필름과 폴리에틸렌 필름을 사용하고 있는데, 외부의 폴리에스터층의 경우에는 상기에서 언급된 관능기가 있는 바인더가 모두 별도의 처리 없이 잘 코팅되나, 내부의 폴리에틸렌층의 경우에는 폴리에틸렌 표면을 코로나 처리해야 전도성 코팅액이 코팅된다. 이때 코로나 처리된 폴리에틸렌의 표면장력이 최소한 35 dynes/cm2이상이 되어야 한다.Antistatic shielding bag mainly uses polyester film deposited by aluminum and polyethylene film among various antistatic products currently used. In case of external polyester layer, all binders with functional groups mentioned above are separately It is coated well without treatment, but in the case of the inner polyethylene layer, the surface of the polyethylene must be corona treated to coat the conductive coating solution. The surface tension of the corona treated polyethylene should be at least 35 dynes / cm 2 .

이와 같이 제조된 필름원단의 표면저항 및 접착력을 측정한 바 표면저항은 106Ω/□ 이었고 ASTM D3359법에 의한 접착력은 5B이었다.As a result of measuring the surface resistance and adhesive force of the film fabric thus prepared, the surface resistance was 10 6 Ω / □ and the adhesive force by the ASTM D3359 method was 5B.
본 발명의 전도성 코팅조성물 및 동 코팅조성물을 포함한 전도성 코팅액을 차폐봉투용 필름원단에 코팅하면 표면저항이 102-1010Ω/□ 범위에서 조절이 가능하면서 전도성 성분의 이행성이 없으면서 수분의존성이 없는 각종 대전방지 차폐봉투제조용 필름원단을 제공할 수 있다.When the conductive coating composition of the present invention and the conductive coating solution including the copper coating composition is coated on the film material for the shielding encapsulation, the surface resistance can be adjusted in the range of 10 2 -10 10 Ω / □ while the water dependence is possible without the performance of the conductive component. Various antistatic shielding bag manufacturing film fabrics can be provided.
