이러한 전자파는 인체에 대한 유해성 뿐만 아니라, 전파방해(EMI: Electro Magnetic Interference)로 인해 다른 전자파를 교란시켜 전기·전자기기 자체에 대하여도 기기장애를 유발하는 원인이 될 수 있으며, 특히 전기·전자기기가 소형화 및 집적화됨에 따라서, 외부 전자파는 물론 자체 발생 전자파에 의한 장애 및 오작동 가능성이 상존한다고 할 수 있다.These electromagnetic waves may disturb other electromagnetic waves due to electromagnetic interference (EMI), as well as harmful to the human body, and may cause device failures for the electrical and electronic devices themselves. As is miniaturized and integrated, it can be said that the possibility of failure and malfunction due to self-generated electromagnetic waves as well as external electromagnetic waves exist.
이러한 전자파에 의한 기기의 영향을 차단하기 위하여 전기·전자기기의 케이스나 주요 회로에 도전성 금속판(일명 실드캔)을 부착하여 금속판의 형태로 전자파 차폐수단을 구성하거나, 전자파 차폐도료인 EMI(ElectroMagnetic Interference)차폐도료를 도포하여 또는 진공증착,스퍼터링등 건식도금)의 방법으로 불요 전자파를 차폐하는 방식이 일반적으로 사용되고 있다.In order to block the influence of the device by electromagnetic waves, a conductive metal plate (also called shield can) is attached to a case or main circuit of an electrical / electronic device to form an electromagnetic shielding means in the form of a metal plate, or EMI (ElectroMagnetic Interference) A method of shielding undesired electromagnetic waves is generally used by applying shielding paint or by vacuum plating or sputtering.
그러나, 휴대폰이나 스마트폰 등과 같은 휴대용 무선정보 단말기의 경우 일면은 디스플레이가 배치되어 있음에 따라 디스플레이 패널을 제외한 나머지 부분에 대한 차폐는 가능할 수 있겠으나 차폐된 전자파가 디스플레이 패널을 통해 방사되는 문제점이 있었다. 즉, 다공성 구조가 아닌 일반 금속구조물 또는 차폐물질을 코팅한 경우에는 전자파를 반사하는 것에 의해 차폐는 가능하지만, 반사된 전자파가 사용자가 신체와 접촉와 근접하는 디스플레이 패널을 통해 방사된다. However, in the case of a portable wireless information terminal such as a mobile phone or a smart phone, since the display is disposed, shielding of the remaining parts except for the display panel may be possible, but shielded electromagnetic waves are radiated through the display panel. . That is, in the case of coating a general metal structure or shielding material other than the porous structure, shielding is possible by reflecting electromagnetic waves, but the reflected electromagnetic waves are emitted through the display panel in which the user is in contact with the body.
한편, 전자파를 효율적으로 흡수·소멸시키는 기술로는 금속 분말을 소결하여 다공성을 갖도록 성형한 소결체가 사용되는 것이다. 즉, 알려진 바에 의하면, 소결체는 모세관 현상에 의해 수분을 흡수하여 서서히 증발시킬 뿐만 아니라 소음과 외부의 충격을 흡수 저감시키는 작용 외에도 전자파를 흡수하여 소멸시킨다.On the other hand, as a technique for efficiently absorbing and extinguishing electromagnetic waves, a sintered compact molded to have porosity by sintering metal powder is used. That is, as is known, the sintered body absorbs moisture by capillary action and gradually evaporates, but also absorbs and extinguishes electromagnetic waves in addition to absorbing and reducing noise and external shock.
이러한 다공성 금속 소결체는 평균입도가 100㎛ 이상인 금속분말을 100∼600MPa 압력하에서 상온 가압하여 예비 소결체를 제조하고, 이때 10∼20%의 기공율을 갖도록 900℃∼1400℃ 범위의 온도에서 120분 이하 시간동안 소결하는 것에 의해 성형된다. The porous metal sintered body is a preliminary sintered body by pressing a metal powder having an average particle size of 100 ㎛ or more at room temperature under a pressure of 100 to 600 MPa, and at this time, 120 minutes or less at a temperature in the range of 900 to 1400 ° C. to have a porosity of 10 to 20%. By sintering during
그러나 종래의 다공성 금속 소결체는 평균입도가 100㎛ 이상인 금속분말을 원재료로 하여 소결함에 따라 큰 입도를 갖는 금속분말로 인하여 표면이 미려한 제품의 제조가 곤란할 뿐만 아니라 가벼운 충격에도 쉽게 파손되는 단점이 있으며, 특히 두께를 10mm 미만으로 제작할 수 없기에 휴대폰이나 스마트폰 등과 같은 소형의 전자기기에 대한 적용이 곤란하여 상품성과 시장성이 낮은 문제점이 있었다.However, the conventional porous metal sintered body has a disadvantage in that it is difficult to manufacture a product with a beautiful surface due to the metal powder having a large particle size as the raw material is sintered using a metal powder having an average particle size of 100 μm or more, and is easily broken even in a light impact. In particular, since the thickness cannot be made less than 10mm, it is difficult to apply to small electronic devices such as mobile phones or smart phones, and thus there is a problem of low marketability and marketability.

본 발명에 따른 이종재질의 고 기능성 박막소재의 제조방법은, 금형의 내부인 성형공간에 금속분말을 충진시키는 충진단계(s10)와, 상기 금형에 충진 된 금속분말을 용융 온도 미만으로 가열하여 다공성 소결체인 1차소결체를 성형하는 1차소결체 성형단계(s20)와, 상기 1차소결체를 밀도 10~98% 및 두께 0.001mm~2mm의 범위를 갖도록 가압 성형하는 2차소결체 성형단계(s30)와, 상기 2차소결체의 표면에 합성수지를 도포하되 0.001mm~1mm의 두께로 도포하여 경화시키는 3차소결체 성형단계(s40) 그리고 필요시 상기 3차소결체에 대하여 표면을 연마하거나 또는 표면에 인쇄 또는 각인을 실시하는 연마·표식 형성단계(s50)로 이루어진다The method for producing a heterogeneous high-functional thin film material according to the present invention includes a filling step (s10) of filling a metal powder in a molding space that is an inside of a mold, and heating the metal powder filled in the mold below a melting temperature to increase porosity. Primary sintered compact forming step (s20) for molding the primary sintered body sintered body, and secondary sintered compact molding step (s30) for press molding the primary sintered compact to have a density of 10 ~ 98% and a thickness of 0.001mm ~ 2mm The third sintered compact forming step (s40) of applying a synthetic resin to the surface of the secondary sintered compact, but applying a thickness of 0.001mm ~ 1mm (s40) and, if necessary, the surface for the tertiary sintered compact or printed or stamped on the surface The polishing and marking forming step (s50) is performed.
금속분말의 Metal powder 충진단계Filling stage (( s10s10 ););
상기 금형은 평판의 박막소재를 성형하기 위한 성형공간을 구비하며, 성형공간에 충진 된 금속분말에 대한 소결이 가능하도록 열변형이 적은 열금형으로 제공되며, 이러한 소결 성형을 위한 금형은 공지의 기술에 의해 실시되어도 무방하므로 상세한 설명은 생략한다. The mold is provided with a molding space for forming a thin film material of a flat plate, and is provided as a thermal mold with little thermal deformation to enable sintering of the metal powder filled in the molding space, and the mold for such sintering molding is a known technique. It may be carried out by, so detailed description thereof will be omitted.
한편, 본 발명에서 사용되는 금속분말 즉, 상기 금형의 성형공간에 충진되는 소결시료는 300℃~1800℃의 용융 온도를 갖는 동계열, 주석 계열, 아연 계열, 알루미늄 계열, 스텐레스 계열의 금속분말이 사용되는 것을 제안하며, 이외에도 은(Ag) 또는 은합금이 사용되는 것도 가능하다. On the other hand, the metal powder used in the present invention, that is, the sintered sample filled in the molding space of the mold is a copper-based, tin-based, zinc-based, aluminum-based, stainless-based metal powder having a melting temperature of 300 ℃ ~ 1800 ℃ It is proposed to be used, and in addition, silver (Ag) or silver alloy may be used.
또한, 상기 금속분말의 입도 즉, 금속분말의 알갱이 크기는 20㎛~200㎛의 크기를 갖는 것을 제안한다. 이는 금속분말의 입도가 20㎛ 미만인 경우에는 소결 후 기공을 제대로 형성하지 못하고 조직이 치밀하게 되는 현상이 있으며, 입도가 200㎛ 이상인 경우에는 소결 후 소결밀도가 낮은 현상으로 인해 쉽게 파손되거나 변형되는 문제점이 있었다. 이러한 금속분말은 상기 금형의 성형공간에 넘치지 않을 정도로 적당량 채워진 상태에서, 금속분말이 완전히 용융되지 않을 정도의 온도로 일정시간 가열되는 것에 의해 1차소결체를 형성하게 된다.In addition, the particle size of the metal powder, that is, the particle size of the metal powder is proposed to have a size of 20㎛ ~ 200㎛. This is because when the particle size of the metal powder is less than 20㎛, the pores do not form properly after sintering and the structure becomes dense, and when the particle size is 200㎛ or more, the sintered density is easily broken or deformed after sintering. There was this. The metal powder is filled in a suitable amount so as not to overflow the molding space of the mold, thereby forming a primary sintered body by heating the metal powder to a temperature such that the metal powder does not melt completely.
1차소결체Primary sintering 성형단계( Molding step ( s20s20 ););
본 발명은 1차소결체를 성형하기 위한 성형조건으로, 상기 금속분말의 소재가 갖는 용융 특성별로 융융점 대비 10%~30% 낮은 온도에서 10분~300분을 가열하여 소결 성형하는 것을 제안한다.The present invention proposes sintering molding by heating 10 minutes to 300 minutes at a temperature of 10% to 30% lower than the melting point for each melting characteristic of the material of the metal powder as molding conditions for forming the primary sintered body.
또한, 소결시 기공을 형성할 수 있을 정도로 금속분말들의 경계면이 서로 안정적으로 융착되어야 하고, 융착된 금속분말들로 이루어진 1차소결체는 단일의 성형체로 접합된 상태를 유지하여야 한다.In addition, the boundary surfaces of the metal powders should be stably fused to each other enough to form pores during sintering, and the primary sintered body made of the fused metal powders should remain bonded to a single molded body.
일례로, 본 발명에서 제안한 금속분말 즉, 소결시료를 구리분말을 사용하였을 경우, 구리는 1084.5℃에서 용융이 일어나므로, 소결온도는 750℃ 조건에서 18~24시간 가열하는 경우 소결 성형밀도가 53~57% 이내의 소결체를 얻을 수 있다. 이외에도 소결 분위기를 상온에서 실시하거나 또는 진공 조건에서 실시하는 것도 가능할 것이다.For example, when the copper powder is used as the metal powder proposed in the present invention, that is, the sintered sample, the copper is melted at 1084.5 ° C. Therefore, when the sintering temperature is heated at 750 ° C for 18 to 24 hours, the sintering molding density is 53. A sintered body of ˜57% can be obtained. In addition, the sintering atmosphere may be performed at room temperature or under vacuum conditions.
2차소결체Second sintering 성형단계( Molding step ( s30s30 ););
본 발명은 상기 소결 성형된 1차소결체에 대하여 30MPa~300MPa의 압력으로 1~20회 프레스 또는 롤러 가압을 실시하되, 밀도 10~98%, 두께 0.001mm~2mm가 되도록 가압하여 2차소결체인 금속박판(20)을 형성한다.According to the present invention, the sintered primary sintered compact is subjected to press or roller pressurization 1 to 20 times at a pressure of 30 MPa to 300 MPa, but is pressurized to have a density of 10 to 98% and a thickness of 0.001 mm to 2 mm. The thin plate 20 is formed.
여기서, 상기 1차소결체에 대한 가압 방법으로는, 다양한 가압장치가 사용될 수 있으며, 본 발명에서는 프레스기 또는 롤러 가압 방식인 롤링·압연기가 사용되는 것을 제안하며, 결과물의 요구 조건과 가압기의 성능에 따라 1~20회 가량 반복하여 실시할 수 있을 것이다. Here, as a pressurization method for the primary sintered body, various pressurization apparatuses may be used, and in the present invention, it is proposed that a rolling or rolling mill, which is a press machine or a roller pressurization method, is used, depending on the requirements of the resultant and the performance of the presser. It may be repeated 1 to 20 times.
특히, 상기 1차소결체에 대한 가압력은 반드시 저압력인 30MPa~300MPa의 범위내에서 이루어져야 하는데, 이는 고압력인 300MPAa 이상으로 1차소결체에 대한 가압을 실시하게 되면, 상기 1차소결체의 내·외부에 균열이 발생하기 때문이다.In particular, the pressing force for the primary sintered body must be made within the range of low pressure 30MPa ~ 300MPa, which is applied to the inside and outside of the primary sintered body when the pressure is applied to the primary sintered body at a high pressure of 300MPAa or more This is because cracking occurs.
한편, 상기 프레스기 또는 롤러 가압 방식의 롤링·압연기에 의해 가압 성형되는 2차소결체는 상·하면이 평탄해지도록 가압되는 것이 바람직하며, 가압 과정을 거치면서 소결 밀도가 높아짐에 따라 금속분말 간의 결합력이 증대되어 결과적으로 내구성 및 탄성이 증대된다. On the other hand, the secondary sintered body which is press-formed by the pressing machine or the roller press-type rolling / rolling machine is preferably pressed so that the upper and lower surfaces are flattened. As the sintered density increases during the pressing process, the bonding force between the metal powders increases. This results in increased durability and elasticity.
또한, 상기 2차소결체 성형단계는 실온 상태에서 진행되어도 무방하나, 금속분말의 소결온도에 대하여 40% 이하의 낮은 온도에서 실시되는 것이 바람직하다. In addition, the secondary sintered compact forming step may be carried out at room temperature, but is preferably carried out at a temperature lower than 40% to the sintering temperature of the metal powder.

In particular, since the electromagnetic wave passes through the synthetic resin material, the synthetic resin in the present invention is preferably applied to the extent that pores exposed to the surface of the secondary sintered body can be shielded.
한편, 본 발명에서의 합성수지는 PP(Polypropylene) PVC(Poly Vinyl Chloride), PC(Polycarbonate), PE(Polyethylene), PET(Poly ethylene terephthalate), 우레탄, 실리콘, 에폭시, ABS(Acrylonitrile Butadiene Styrene), UV수지(Ultraviolet-Resin) 중 어느 하나 또는 하나 이상을 조성한 조성물이 사용될 수 있으며, 이러한 합성수지의 형성 두께는 0.001mm~1mm를 갖는다.On the other hand, the synthetic resin in the present invention PP (Polypropylene) PVC (Poly Vinyl Chloride), PC (Polycarbonate), PE (Polyethylene), PET (Polyethylene terephthalate), urethane, silicone, epoxy, ABS (Acrylonitrile Butadiene Styrene), UV A composition in which any one or more than one resin (Ultraviolet-Resin) is formed may be used, and the thickness of the synthetic resin may be 0.001 mm to 1 mm.
한편, 본 발명에서의 3차소결체를 성형하기 위한 방법으로는 다음과 같다.On the other hand, the method for molding the tertiary sintered body in the present invention is as follows.
첫째, 액상의 합성수지를 스프레이 분사로 형성시키는 방법,First, a method of forming a liquid synthetic resin by spray injection,
둘째, 실크인쇄로 피막을 형성시키는 방법,Secondly, a method of forming a film by silk printing;
셋째, 2차 소결체를 인서트 사출하여 그 표면으로 사출 성형하는 방법,Thirdly, insert injection molding the secondary sintered compact and injection molding onto the surface thereof;
넷째, 2차소결체의 외면으로 합성수지 시트재를 60℃~200℃의 온도로 가열하여 열 융착으로 형성하는 방법.Fourth, a method of forming a synthetic resin sheet material by heating at a temperature of 60 ℃ to 200 ℃ to the outer surface of the secondary sintered body.
이러한 방법에 의해 상기 2차소결체의 외면을 합성수지재로 감싼 뒤에는, 상기 합성수지의 종류에 따라 자연건조, 열 경화, UV 경화 방법 중 어느 하나에 의해 경화가 이루어진다. 즉, 위의 다양한 방법으로 목적물인 2차 소결체의 외면을 합성수지로 감싸도록 하는 것은, 결과적으로 상기 2차 소결체가 외부로 노출되는 것을 차단함으로써, 오랜 기간 사용시 2차 소결체인 금속이 갖는 자연적인 산화, 변색, 부식 등의 문제를 차단하도록 하고, 또한, 합성수지가 갖는 물리적 특성에 의해 2차 소결체가 외력에 의해 쉽게 손상 또는 파손되는 것을 억제하도록 함으로써 가공 및 취급을 용이하게 하여 작업성을 양호하게 할 수 있다.After the outer surface of the secondary sintered body is wrapped with the synthetic resin by this method, curing is performed by any one of natural drying, thermal curing, and UV curing according to the type of the synthetic resin. That is, to wrap the outer surface of the secondary sintered body as a synthetic resin by the various methods described above, as a result, the secondary sintered body is prevented from being exposed to the outside, thereby the natural oxidation of the metal that is the secondary sintered body when used for a long time It is possible to prevent problems such as discoloration, discoloration, and corrosion, and to prevent the secondary sintered body from being easily damaged or damaged by external force due to the physical properties of the synthetic resin, thereby facilitating processing and handling, thereby improving workability. Can be.
한편, 상기 3차소결체 성형단계에서 우선적으로 고려되어야 할 부분은 합성수지가 갖는 탄성 및 항균 첨가물이 혼합되었을 때 항균성 등을 안정되게 유지시키는 것이며, 이를 위해 본 발명에서의 합성수지의 두께는 0.001mm~1mm의 범위 내에서 형성되는 것을 제안한다. 만약, 0.001mm 미만의 두께로 합성수지를 형성하는 경우에는 합성수지가 갖는 탄성 및 결합성 향상의 효과를 기대할 수 없고, 합성수지의 두께를 1mm 이상으로 하는 경우에는 성형공정에 제약을 받을 뿐만 아니라 지나친 두께 증가로 인해 적용 대상에 제약을 받는 단점이 있기 때문이다.On the other hand, the part to be considered first in the tertiary sintered body molding step is to maintain the antibacterial stability when the elastic and antimicrobial additives of the synthetic resin is mixed, for this purpose, the thickness of the synthetic resin in the present invention is 0.001mm ~ 1mm It is proposed to be formed within the range of. If the thickness of the synthetic resin is less than 0.001mm, the elasticity and bonding properties of the synthetic resin cannot be expected. If the thickness of the synthetic resin is 1 mm or more, the molding process is restricted and excessively thick. This is because there is a disadvantage that is limited by the application.
또한, 상기 3차 소결체를 성형하기 위한 합성수지는 은나노액 또는 피톤치드액 중 어느 하나 또는 둘 모두를 조성한 조성물로 이루어진 항균 첨가물을 포함하는 것을 제안하며, 이러한 항균 첨가물의 기능 및 조성비는 다음과 같다. In addition, the synthetic resin for molding the tertiary sintered body is proposed to include an antimicrobial additive made of a composition of any one or both of the nano-nano solution or phytoncide solution, the function and composition ratio of these antimicrobial additives are as follows.
첫째, 은나노(Nano Silver)는 은의 입자가 작으면 작을수록 합성수지와 혼합되었을 때 분포도, 즉 표면적이 상대적으로 넓어지므로, 항균/제균력은 높아진다. 이러한 은나노액을 합성수지와 혼합할 때에는 경제성과, 항균성 등을 고려하여야 하며, 본 발명에서는 반복적인 실험을 통해 합성수지와 은나노액의 조성비를 90~96:10~4 의 중량비율로 혼합하는 것을 제안한다. 여기서 은나노액이 합성수지에 대하여 3% 이하로 첨가되는 경우에는 항균력이 급격하게 낮아져 항균성이 불량하며, 상기 은나노액이 10%를 초과하는 경우에는 경제성이 떨어지는 단점이 있다.First, since silver nanoparticles have a smaller particle size, the distribution, that is, the surface area of the silver nanoparticles becomes larger when mixed with the synthetic resin, and thus, the antibacterial / bacterial activity is high. When the silver nano liquid is mixed with the synthetic resin, economical efficiency and antimicrobial properties should be considered. In the present invention, the composition ratio of the synthetic resin and the silver nano liquid is proposed to be mixed at a weight ratio of 90 to 96:10 to 4 through repeated experiments. . In this case, when the silver nano liquid is added to 3% or less with respect to the synthetic resin, the antimicrobial activity is sharply lowered, and thus the antimicrobial property is poor. When the silver nano liquid is more than 10%, the economic efficiency is inferior.
둘째, 피톤치드(phytoncide)는 테르펜을 주성분으로 하여 페놀호합물, 알칼로이드 성분, 글리코시드를 포함하는 물질로서, 주로 소나무(적송)이나 편백나무에서 추출된다. 이러한 피톤치드는 앞서 설명한 은나노액에 비하여 가격이 저렴하므로 혼합비율을 높여도 무방하다. 본 발명에서는 합성수지와 피톤치드액을 3~9 : 7~1의 중량비율로 혼합되는 것을 제안한다. Second, phytoncide is a substance containing a phenol compound, an alkaloid component, and glycoside mainly composed of terpene, and is mainly extracted from pine (cypress) or cypress. Such phytoncide may have a lower price than the silver nano-solution described above, and thus may increase the mixing ratio. In the present invention, it is proposed that the synthetic resin and the phytoncide liquid are mixed in a weight ratio of 3 to 9: 7 to 1.
한편, 상기 항균 첨가물을 혼합한 합성수지는 도 8 및 도9에 나타내 보인 바와 같이 수지 자체에 항균기능을 갖게 되며, 이러한 항균성을 갖는 합성수지는 상기 2차소결체의 표면에 형성된 무수히 많은 기공으로 침투하여 경화되는 것에 의해 쉽게 벗겨지거나 손상되지 않고 반영구적으로 항균기능을 유지하게 된다. Meanwhile, as shown in FIGS. 8 and 9, the synthetic resin mixed with the antimicrobial additives has an antimicrobial function in the resin itself, and the synthetic resin having such antimicrobial properties penetrates and hardens into a myriad of pores formed on the surface of the secondary sintered body. By being easily peeled off or damaged, the antibacterial function is maintained permanently.

한편, 3차소결체에 대하여 추가적인 가압을 실시하여 그 두께를 감소시키는 것도 가능하며, 이때의 가압공정은 2차소결체의 공정과 마찬가지로 프레스기 또는 롤러가압 방식인 롤링·압연기가 사용되는 것을 제안하며, 결과물의 요구 조건과 가압기의 성능에 따라 1~20회 가량 반복하여 실시할 수 있을 것이다. On the other hand, it is also possible to reduce the thickness of the third sintered body by additional pressurization, in which the pressurization process, like the process of the secondary sintered body, suggests that a rolling or rolling press of a press or roller press type is used. Depending on the requirements of the press and the performance of the pressurizer may be repeated about 1 to 20 times.

At this time, the sintering temperature is different depending on the material of the metal powder used, and in order to control the porosity of the metal, low melting point material (EX: synthetic resin-wax powder, plastic powder, metal powder-tin) It is possible to have more porosity in the case of compression sintering by mixing.
또한 위의 금속분말의 경우 금속의 융점 온도가 300 ~ 1,800도 범위 이내의 금속소재를 활용하는 것이 바람직하며, 주로 동계열 금속, 알루미늄계열, 스텐레스 합금 등등의 금속분말을 압축하여 일정한 형태의 모양을 갖춘 후 이를 소결 하여 1차소결체를 성형하되, 금속의 재질이 갖는 용융점 보다 낮은 온도에서 소결하여야 한다. 이렇게 소결된 1차소결체의 경우 저융점 물질이 차지하고 있는 공간만큼 기공을 성형할 수 있다.In addition, in the case of the above metal powder, it is preferable to use a metal material having a melting point temperature of the metal within the range of 300 to 1,800 degrees, and mainly compresses the metal powder of copper series metal, aluminum series, stainless alloy, etc. After sintering, the primary sintered body is molded and sintered at a temperature lower than the melting point of the metal material.
