이하, 본 발명 자석종이의 제조단계별(제조공정별)로 자세히 설명하고자 한다.Hereinafter, the present invention will be described in detail by manufacturing step (by manufacturing process) of the magnetic paper.

1.One. 자성재료 준비단계Magnetic material preparation step

자성재료의 원료가 되는 점액상태의 접착제(接着劑)와, 300 메쉬(mesh) 입도 이상의 자성분말(粉末)을 준비하도록 한다. 상기 접착제로는 변질이 어려운 라텍스에멀죤과 변성전분(산화시킨 전분, 효소를 첨가한 전분 등) 및 천연고무 등이 주로 이용된다.A mucus adhesive, which is a raw material of the magnetic material, and a magnetic powder having a particle size of 300 mesh or more are prepared. As the adhesive, latex emulsion zones which are difficult to deteriorate, modified starch (oxidized starch, starch added with enzyme), natural rubber, and the like are mainly used.

이를테면, 자석종이의 용도나 유연성 정도에 따라 라텍스에멀죤만 사용하거나 라텍스에멀죤과 변성전분(산화시킨 전분, 효소를 첨가한 전분 등)을 혼합 사용하거나, 천연고무 단독으로 사용할 수 있다.For example, depending on the purpose and flexibility of the magnet paper, only the latex emulsion zone may be used, or the latex emulsion zone and modified starch (oxidized starch, starch added with enzyme, etc.) may be used, or natural rubber alone may be used.

라텍스에멀죤과 변성전분을 혼합 사용하는 경우, 30% ~ 70% : 70% ~ 30%의 무게비로 혼합사용할 수 있으며, 라텍스에멀죤 대신 폴리비닐 알콜(PVA)이나 폴리비닐 아세테이트(PVAC) 등을 사용할 수도 있다. 그리고, 자성분말은 자화 또는 착자에 의해 영구자석이 되는 경자석 금속분말이나 영구자석 제조에 사용되는 소결자성용의 분말 자성재료 등을 사용하도록 한다.In case of mixing latex emulsion zone and modified starch, 30% ~ 70%: 70% ~ 30% can be mixed and used instead of latex emulsion zone polyvinyl alcohol (PVA) or polyvinyl acetate (PVAC) Can also be used. As the magnetic powder, a hard magnetic metal powder which becomes a permanent magnet by magnetization or magnetization, or a powder magnetic material for sintered magnet used for the production of permanent magnets.

상기 천연고무는 자성재료에 유연성을 부여하게된다. 물론, 합성고무를 사용할 수도 있지만 유연성 면에서 보다 우수한 천연고무를 사용하는 것이 바람직하다.The natural rubber gives flexibility to the magnetic material. Of course, synthetic rubber may be used, but it is preferable to use natural rubber which is superior in terms of flexibility.

2.2. 자성재료 혼합단계Magnetic material mixing step

상기에서 준비된 접착제(接着劑)(2a)와 300 메쉬(mesh) 입도 이상의 자성분말(2b)을 혼합시켜 점액 상태(粘液狀態)의 자성재료(磁性材料)를 얻도록 한다.The adhesive 2a prepared above and the magnetic powder 2b having a particle size of 300 mesh or more are mixed to obtain a slime-like magnetic material.

상기 접착제(2a)와 자성분말(2b)의 혼합비는 희망하는 자성정도에 따라 70% ~ 3% : 30% ~ 97%의 무게비율로 20분 이상 충분히 혼합시켜 30% ~ 80%의 농도와, 100 ~ 3,000CPS의 점도를 갖는 점액 상태의 자성재료(2)를 얻도록 한다.The mixing ratio of the adhesive (2a) and the magnetic powder (2b) is 30% to 80% concentration by mixing enough for more than 20 minutes at a weight ratio of 70% to 3%: 30% to 97% according to the desired magnetic degree, The magnetic material 2 in the state of slime having a viscosity of 100 to 3,000 CPS is obtained.

그리고, 자성분말(2b)의 비중이 접착제보다 높아 침전될 경우 0.5 ~ 0.05% 정도의 분산제를 혼합시켜 자성분말(2b)의 침전을 방지할 수 있다.When the specific gravity of the magnetic powder 2b is higher than that of the adhesive, the magnetic powder may be mixed with 0.5 to 0.05% of a dispersant to prevent precipitation of the magnetic powder 2b.

본 발명에서 자성재료(2)에 색상을 부여하고자 하는 경우, 소량의 안료를 첨가할 수 있다. 이를테면, 액상의 자성재료에 5% ~ 30%의 안료를 무게비로 혼합시켜 색상을 부여할 수 있다. 그리고, 접착제에 의해 자성재료의 전성과 연성(ductility)이 부여된다.In the present invention, when it is desired to give a color to the magnetic material 2, a small amount of pigment may be added. For example, 5% to 30% of the pigment may be mixed with the liquid magnetic material to give a color. Then, the adhesiveness imparts the malleability and ductility of the magnetic material.

3.3. 자성재료 도포단계Magnetic material application step

도포기계를 이용하여 점액 상태의 자성재료를 도 2와 같이 종이(3)의 한 쪽면에 고른 두께로 도포하도록 한다. 상기 도포두께는 종이(3)의 무게나 필요로하는 자력(磁力)을 감안하여 달라진다. 예컨데, 무게 기준으로 50 ~ 1,000g/㎡, 두께기준으로는 30 ~ 500㎛ 범위로 도포할 수 있으며, 한 번의 도포로 원하는 두께를 얻지 못하는 경우 여러 번 도포할 수 있다.A magnetic material in a slime state is applied to one side of the paper 3 with an even thickness by using an application machine. The coating thickness is changed in consideration of the weight of the paper 3 and the required magnetic force. For example, it can be applied in the range of 50 ~ 1,000g / ㎡ by weight, 30 ~ 500㎛ based on the thickness, can be applied several times if the desired thickness can not be obtained by one application.

물론, 본 발명에서 종이(3)의 한 쪽면 만 아니라, 종이(3)의 양쪽면에 자성재료(2)를 도포 처리할 수도 있다.Of course, in the present invention, the magnetic material 2 may be applied to both sides of the paper 3 as well as to one side of the paper 3.

본 발명에서 적용할 수 있는 종이(3)로는 광고효과나 메모지의 용도에 따라 아트지, 백상지, 백판지, 골판지 등을 예로 들 수 있으며, 도포기계로는 제지용 코타 이를테면, 에어나이프 코타, 리버스 롤 코타, 로드바 코타, 브래이드 코타 등을 그 예로 들 수 있다.The paper 3 applicable to the present invention may include art paper, woodfree paper, white paper, corrugated paper, etc. according to an advertisement effect or a purpose of a memo paper, and the coating machine may be a paper coty, for example, an air knife cotta, a reverse roll cotta. For example, rod bar cotta, braid cotta, and the like.

4.4. 자성재료 건조단계Magnetic material drying step

종이와, 종이에 도포된 자성재료의 변형이나 손상이 없는 범위내에서 최종 함수율이 5% 전ㆍ후 또는 5% 이하가 되도록 건조한다. 건조과정을 예로 들면, 열풍 건조방식의 건조기, 복사식 전열 건조기등을 이용하여 100℃ ~ 200℃의 열풍으로 도포된 자성재료(2)를 수 초 내지 수 십초 간 건조시키면 된다.It is dried so that the final moisture content is before and after 5% or 5% or less within the range without deformation or damage of the paper and the magnetic material applied to the paper. For example, a drying process may be performed by drying the magnetic material 2 coated with hot air at 100 ° C. to 200 ° C. for several seconds to several tens of seconds using a hot air drying type dryer or a radiant heat transfer dryer.

5.5. 자성재료 평할단계(자성재료 광택단계)Magnetic Material Leveling Stage (Magnetic Material Polishing Stage)

종이의 한쪽면에 도포 및 건조된 자성재료의 표면을 평할 처리하는 광택공정의 일종으로, 자성재료(2)가 도포된 자석종이(1)를 도 5와 같이 카렌다(금속롤 카렌다 등)의 복수 롤러(4) 사이로 통과시켜 충분한 광택을 얻도록 한다.It is a kind of gloss process for leveling the surface of the magnetic material coated and dried on one side of paper, and a plurality of calendars (metal roll calender, etc.) of the magnetic paper 1 coated with the magnetic material 2 are shown in FIG. Pass through the rollers 4 to achieve sufficient gloss.

상기 자석종이(1)가 복수 롤러(4) 사이로 통과하는 시간은 광택조건, 광택정도, 자석종이, 자성재료(2)의 도포두께, 종이(3)의 종류 및 재질등에 따라 수 초 내지 수십 초가 된다.The time that the magnet paper 1 passes between the plurality of rollers 4 is several seconds to several tens of seconds depending on the gloss condition, the degree of gloss, the magnet paper, the coating thickness of the magnetic material 2, the type and material of the paper 3, and the like. do.

6.6. 자석종이 인쇄단계Magnetic paper printing stage

자성재료(2)가 도포 건조된 자석종이(1)의 표면에 도시안된 인쇄기로 인쇄하여 인쇄층을 형성하도록 한다.The magnetic material 2 is printed on a surface of the magnetic paper 1 coated and dried to form a printing layer by printing with a printing machine (not shown).

상기 인쇄는 착자를 전후하여 시행할 수 있다. 이를테면, 자석종이(1)의 자력이 인쇄과정이나 인쇄기에 영향을 주는 경우, 이를테면 자력에 의해 종이의 원활한 이동이 어렵거나 인쇄품질에 영향을 주는 경우에는 인쇄를 먼저하고 착자를 나중에 할 수 있다. 그렇치 않는 경우, 착자를 먼저하고 인쇄를 나중에 할 수 있을 것이다.The printing can be carried out before and after magnetization. For example, when the magnetic force of the magnet paper 1 affects the printing process or the printing machine, for example, when the smooth movement of the paper is difficult or affects the print quality by the magnetic force, printing may be performed first and magnetization may be performed later. If not, you will be able to magnetize first and print later.

7.7. 자성재료 착자단계Magnetic material magnetization stage

광택처리된 자성재료(2) 부분에 도시안된 착자요크(착자기 등) 등으로 착자시켜 도 6과 같이 다극형의 영구자성(영구자석)을 부여하도록 한다. 그리고, 자극(磁極)을 형성하는 간극(d)은 자석종이(1)의 크기나 두께에 따라 달라질 수 있으나 대체로 1㎜ ~ 10㎜ 정도로 할 수 있으며, 자성재료의 도포량이 적을 수록 자극(d)간의 거리는 좁게 형성하여 충분한 자력이 유지되도록 한다.The magnetized yoke (magnetizer, etc.) not shown is magnetized to the polished magnetic material 2 to impart a multi-pole permanent magnet (permanent magnet) as shown in FIG. The gap d forming the magnetic pole may vary depending on the size or thickness of the magnet paper 1, but may be about 1 mm to 10 mm, and the smaller the application amount of the magnetic material is, the more the magnetic pole d is formed. The distance between them is narrow, so that sufficient magnetic force is maintained.

8.8. 자석종이 절단단계Magnetic paper cutting step

인쇄된 종이를 필요한 크기로 절단시켜 사용하도록 한다.Cut the printed paper to the required size.

한편, 본 발명에서 강자력(强磁力)이 요구되는 경우, 자석종이(1)의 두께가 보다 두꺼워지며, 경우에 따라서는 인쇄가 곤란할 수 있으므로 도 4와 같이 자석종이(1)의 인쇄층(5) 대신 점착제를 도포하여 점착제층(6)을 형성하고, 점착제층(또는 접착제층)(6)의 상부면에 이형지(또는 박리지 등)(7)를 점착시켜 분리할 수 있게 구성함으로서, 나중에 이형지(7)를 제거한 다음 인쇄된 종이(8)를 상기 점착제층(6)에 점착시켜 붙이는 방법으로 인쇄효과를 얻을 수 있다.On the other hand, when a ferromagnetic force is required in the present invention, the thickness of the magnetic paper 1 becomes thicker, and in some cases, printing may be difficult, so as shown in FIG. 4, the printed layer of the magnetic paper 1 ( 5) Instead of applying an adhesive to form a pressure-sensitive adhesive layer (6), and by releasing the release paper (or release paper, etc.) 7 on the upper surface of the pressure-sensitive adhesive layer (or adhesive layer) 6, Later, the release paper 7 may be removed, and then the printed paper 8 may be adhered to the pressure-sensitive adhesive layer 6 to obtain a printing effect.

본 발명은 인쇄층(5) 또는 인쇄된 종이(8)에 적당한 인쇄를 하면 점착 스티커를 대신하는 광고 전단지, 메모지 등으로 이용할 수 있게된다.According to the present invention, proper printing on the printed layer 5 or printed paper 8 can be used as an advertisement leaflet, a memo paper, or the like instead of an adhesive sticker.

그리고, 본 발명 자석종이(1)의 사용방법은 일반 접착제 또는 접착제를 이용한 일반 스티커와는 다른 양상이다. 즉, 다극 착자된 자성재료면을 철금속 제품(철제부품 등을 포함한다.)의 표면으로 접근시키면 자력에 의해 자석종이가 상기 철금속 제품에 흡착되어 붙어 있게되고, 이들 철금속 제품으로부터 쉽게 분리시킬 수 있으며, 접착제나 점착제가 아닌 자력으로 흡착시키는 방법이므로 종래 문제점들, 이를테면, 물체의 표면이나 건물의 벽면등으로부터 전단지를 떼어낼 때 접착제에 의해 분리가 어려운 점과, 접착제(또는 점착제)가 물체의 표면이나 건물의 벽면에 잔류하면서 오염되고, 또한 오랫동안 그 흔적이 남아 물체나 건물의 미관이 크게 저하시키는 등의 문제점이 해소되며, 생분해 또는 자연분해되는 종이를 이용하므로 환경친화적이다.In addition, the use method of the magnetic paper 1 of the present invention is different from that of a general sticker using a general adhesive or an adhesive. In other words, approaching the surface of a multi-pole magnetized magnetic material to the surface of a ferrous metal product (including iron parts, etc.) causes magnetic paper to be adsorbed onto the ferrous metal product by magnetic force and easily separated from the ferrous metal product. Since it is a method of adsorbing by magnetic force rather than adhesives or adhesives, it is difficult to separate them by adhesives when removing leaflets from the surface of an object or the wall of a building, and the adhesive (or adhesive) It remains contaminated while remaining on the surface of an object or on the wall of a building, and the traces remain for a long time, and problems such as deterioration of the aesthetics of the object or building are largely solved.

이상과 같이 설명한 본 발명은 본 실시 예 및 첨부된 도면에 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 여러가지 치환, 변형 및 변경이 가능하며, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 자명한 것이다.The present invention as described above is not limited to the present embodiment and the accompanying drawings, various substitutions, modifications and changes are possible within the scope without departing from the technical spirit of the present invention, which is usually in the art It is self-evident for those who have knowledge.
