Description
본 발명은 전자파 차폐용 스크린 필터(screen filter)에 사용되는 금속도금한 폴리에스텔포지의 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a metal-plated polyester paper used in a screen filter for shielding electromagnetic waves.
최근 전자기기에서 발생되는 전자파가 신체 및 주변기기에 악영향을 미치고 있는 것으로 알려지게 됨에 따라 전자파를 차폐 또는 흡수할 수 있는 전자파 차폐용 폴리에스텔 스크린 필터(screen filter)가 개발되고 있으나, 종래의 전자파 차폐용 폴리에스텔포지는 일본특공소 40-27400호로 알려진 바와 같이 수지가공하여 Sn으로 감수성화 한다음 Pd으로 활성화하고 Ni 도금액에서 도금하여 도전성을 주고 있으나 이와 같이 제조된 것을 직물의 눈(目)이 막혀있으므로 광 투과가 요구되는 스크린 필터용으로는 사용하기 어렵고, 또 이것은 에칭(etching)없이 수지위에 도금하였으므로 도금금속 내구성이 불량하며, 도금금속위의 후 처리가 되어있지 않으므로 공기 또는 수분에 의하여 산화되기 쉬우며, 활성화공정에서 사용하는 Pd는 가격이 비쌀뿐 아니라 밀착력이 약하여 에칭이 적게된 포지에 부착되는 경우에는 수세시 Pd가 수세액에서 이탈되어 도금이 거의 되지않는 문제점이 있다.Recently, as electromagnetic waves generated from electronic devices are known to adversely affect the body and peripheral devices, polyester screen filters for shielding or absorbing electromagnetic waves have been developed, but conventional electromagnetic shielding Polyester forge is resin-processed, known as Japanese Patent Application No. 40-27400, susceptible to Sn, activated with Pd and plated in Ni plating solution to give electroconductivity. It is difficult to use for screen filter that requires light transmission, and it is plated on resin without etching, so the durability of plating metal is poor, and it is easy to be oxidized by air or moisture because it is not processed after plating metal. Pd used in the activation process is not only expensive but also has high adhesion In the case where the adhesive is weak and adhered to a forge less etched, there is a problem in that Pd is removed from the washing solution and the plating is hardly performed at the time of washing.
이를 방지하기 위해서 에칭을 많이 하게 되면 Pd의 탈락을 방지할 수 있으나 그 대신에 많이 에칭된 포지는 강도 및 형태안정성이 저하되고, 도금시 포지에서 Pd가 미량만이라도 이탈되면 도금액이 분해되기 때문에 사용하기가 까다로운 결점이 있다.In order to prevent this, it is possible to prevent the dropping of Pd, but instead, the heavily etched forge decreases its strength and form stability, and the plating solution decomposes even if only a small amount of Pd is removed from the forge during plating. There is a tricky flaw.
또한 폴리에스텔 포지를 유기용제에 용해된 Pd를 함유하는 유기금속 화합물 용액에 처리하여 유기금속화합물에 의한 Pd함유 컴플렉스(Complex)를 형성시킨 후 유기용제를 증발시키고 나서 통상의 무전해도금을 함으로서(미국특허 4493861) 도전성을 주는 방법이 있으나 유기용제 사용에 의한 유해성 문제가 발생하고 에칭후의 Sn에 의한 감수성화, Pd에 의한 활성화 대신에 유기금속 화합물용액에 의해 생성된 Pd함유 컴플렉스(Complex)는 일정한도 이상의 밀착력을 갖지 못해 수세에 의해 이탈되거나 수세하지 않고 도금액에 넣었을 경우 도금 반응시 이탈되어 도금액을 분해시키는 결점이 있다.In addition, by treating the polyester forage to a solution of an organometallic compound containing Pd dissolved in an organic solvent to form a Pd-containing complex by the organometallic compound, and then evaporated the organic solvent, followed by ordinary electroless plating ( U.S. Patent No. 4493861) There is a method of providing conductivity, but the problem of harmfulness caused by the use of organic solvent occurs, the Pd-containing complex produced by the organometallic compound solution instead of the susceptibility by Sn after the etching and the activation by Pd is constant. If the coating liquid does not have the adhesive strength of more than the degree is removed by water washing or put into the plating liquid without washing with water, there is a defect of decomposing during plating reaction to decompose the plating liquid.
본 발명자들은 이러한 결점을 해결하기 위하여 노력한 결가 전자파 차폐용 포릴에스텔 스크린 필터를 제조할대 밀착력이 강하면서도 다소 도금액에 들어가도 액을 분해시키지 않는 활성화제이인 은을 사용한 다음 도금하고, 아크릴수지 처리함으로서 포지의 에칭을 적게하고 강력을 저하시키지 않으면서 전자파 차폐성 및 내구성이 우수한 전자파 차폐용 스크린 필터를 제조하게 되었다.The inventors of the present invention made a polyelectromagnetic screen filter for shielding electromagnetic waves, which has been made to solve such drawbacks, by using silver which is an activating agent that has strong adhesion but does not decompose a liquid even in a plating solution, and then plated and treated with acrylic resin. The electromagnetic wave shielding screen filter which is excellent in electromagnetic wave shielding property and durability is reduced, without reducing the etching of an iron and reducing the strength.
이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 폴리에스텔 섬유사로 된 포지에 적용된다.The present invention is applied to forge made of polyester fiber yarn.
일반 폴리에스텔사로 제직한 포지를 에칭공정에서 4g/ℓ의 가성소다용액으로 10-14%감량시키셔 섬유표면에 전처리제가 밀착될 수 있고 접촉면적을 넓혀주는 요철을 형성시킨다.Forged fabrics made of ordinary polyester yarn are reduced by 10-14% with 4g / l caustic soda solution in the etching process to form unevennesses that can bring the pretreatment to the surface of the fiber and increase the contact area.
이처럼 처리된 포지를 Sn++이온이 함유되어 있는 SnCl2와 HCl 및 pH 완충액 등으로 조성된 감수성욕에 침지하여 섬유내부에 Sn++이온을 침투시키고 이어서 이것을 수세하여 섬유표면에 부착된 Sn++이온을 세정제거한 다음 Ag 이온이 함유되어 있는 AgNO3와 NH4OH 및 환원 방지제 등으로 조성된 활성화욕에 침지시킨다.The treated pores were immersed in a susceptible bath composed of SnCl 2 containing H 2 + ions, HCl and pH buffer, infiltrating Sn ++ ions into the fiber, and then washed with water and Sn + attached to the fiber surface. + After removing ions, they are immersed in an activation bath composed of AgNO 3 and NH 4 OH containing Ag ions and a reducing agent.
이렇게 하면 섬유내부에 Ag++이온과 Sn++이온이 아래식(1)과 같은 반응을 일으켜서 섬유내부에서 Ag 금속을 석출 형성시킨다.In this case, Ag ++ ions and Sn ++ ions react with each other to form Ag metal in the fiber.
이렇게 처리된 표면에 요철이 형성된 폴리에스텔 포지는 다음의 통상적인 무전해 도금욕에서 처리하면 도금촉매인 Ag에 의해서 아래식(2)와 같이 반응하여 Ni,Cu등의 피막을 섬유상에 석출형성 시킴으로써 금속도금포지가 완성되는 것이다.The polyester forge having irregularities formed on the treated surface is reacted by Ag as a plating catalyst as shown in the following formula (2) when treated in the following conventional electroless plating bath to precipitate and form a film such as Ni and Cu on the fiber. Metal-plated wrapping paper is completed.
(단, Me는 Ni,Cu등의 금속임)(Me is a metal such as Ni, Cu, etc.)
본 발명에 적응하는 바람직한 감수성욕과 활성욕의 조성은 아래와 같다.The composition of the preferred sensitive and active baths adapted to the present invention is as follows.
상기한 바와 같이 제조된 금속도금포지는 내세탁과 내마모성이 약하고, 공기나 수분 분위기에 노출되어 산화되기 쉬우므로 탄소를 함유한 자기가교형 아크릴에멀젼 수지용액에 전착도장한 후 100∼150℃에서 열처리 하여 금속피막위에 얇은 보호막을 형성시켜 준다.The metal-plated wrapping paper prepared as described above is weak in washing and abrasion resistance, and is easily oxidized by being exposed to air or moisture atmosphere, and is then heat-treated at 100 to 150 ° C after electrodeposition coating to a carbon-containing self-crosslinking acrylic emulsion resin solution.
