초박막 열확산시트 및 그 제조방법Ultra Thin Thermal Diffusion Sheet and Manufacturing Method Thereof
본 발명은 초박막 열확산시트 및 그 제조방법에 관한 것으로서, 더욱 상세하게는 각종 전기전자제품 및 태양열발전기의 열확산용 방열시트 등으로 사용하기 위한 초박막 열확산시트 및 그 제조방법에 관한 것이다.The present invention relates to an ultra-thin thermal diffusion sheet and a method for manufacturing the same, and more particularly, to an ultra-thin thermal diffusion sheet for use as a heat diffusion sheet for thermal diffusion of various electrical and electronic products and solar generators, and a manufacturing method thereof.
최근 TV나 노트북, 컴퓨터, 스마트폰, 및 태양열 발전기 등과 같은 각종 전기전자제품 및 태양열 발전기는 고성능화, 소형화, 슬림화, 곡면화 및 아몰퍼스(Amorphous)등으로 인해 기술이 집약되고 있으므로 이에 대응할 수 있는 구조적 물성이 필요하고 발열량이 증가되고 있는 추세에 있으며, LED 전등을 비롯한 LED 적용 제품들 또한 발열량이 많아 열을 효율적으로 확산 또는 방출시키는 기술이 요구되고 있다.Recently, various electrical and electronic products such as TVs, laptops, computers, smart phones, and solar generators and solar generators are concentrated due to high performance, miniaturization, slimness, curved surface, and amorphous, so that they can respond to structural properties. There is a need for this and heat generation is increasing, LED application products, including LED lamps also have a large amount of heat generation, there is a demand for technology to efficiently diffuse or dissipate heat.
이에 따라, 각종 전기전자제품에는 열의 확산 또는 방출을 통한 제품 보호를 위해 열확산시트 또는 방열시트가 적용되고 있다.Accordingly, a thermal diffusion sheet or a heat dissipation sheet is applied to various electrical and electronic products to protect the product through the diffusion or release of heat.
이러한 용도로 사용되고 있는 종래 열확산시트 또는 방열시트는 팽창 흑연에 가소제로서 티탄에이트 및 용제로서 IPA 등을 혼합하여 가소성을 부여하고 압연한 후 점착시트와 합지하는 형태로 제조하여 사용하고 있다.The conventional thermal diffusion sheet or heat dissipation sheet used for this purpose is manufactured by mixing titaniumate as a plasticizer and IPA as a solvent, adding plasticity to the expanded graphite, rolling it, and then laminating it with an adhesive sheet.
하지만, 상기의 종래 제조방법에 의해 제조된 열확산시트 또는 방열시트는 팽창 흑연을 제조하기 위하여 황산 등의 강산을 사용하므로 공정이 위험하고 불순물이 남게 되며, 연성화시키기 위해 가소제로서 사용하는 티탄에이트는 불휘발성으로 잔류하게 되므로 전도성을 저감시킨다.However, the thermal diffusion sheet or the heat dissipation sheet prepared by the conventional manufacturing method uses a strong acid such as sulfuric acid to produce expanded graphite, so the process is dangerous and impurities remain, and titaniumate used as a plasticizer for softening is not used. It remains volatile, reducing conductivity.
또한, 산처리→건조→환원→정제→건조→가소제 첨가→용제 첨가→압연→건조→시트 합지 등의 과정을 순차 수행하여야 하는 것으로서, 다수의 공정을 거쳐야 하므로 복잡하고 원가가 높으며, 또한 흑연의 취성(Brittleness)으로 인하여 초 박막 시트를 제조하기 어려우며, 제품사용 시 작은 굴절에도 손쉽게 파손되는 문제점이 있었다.In addition, acid treatment → drying → reduction → purification → drying → plasticizer addition → solvent addition → rolling → drying → sheet lamination, etc., must be carried out sequentially. Due to brittleness, it is difficult to manufacture an ultra thin sheet, and there is a problem that it is easily broken even with small refraction when using the product.
덧붙여, 종래에는 수지용액과 혼합하여 코팅하는 방법으로 제조하기도 하나, 절연성인 수지에 의해 전도성이 현저하게 저감되는 문제점이 있었다.In addition, although conventionally manufactured by mixing and coating with a resin solution, there is a problem that the conductivity is significantly reduced by the insulating resin.
본 발명의 일 실시예는, 순수 탄소미립자(그래핀,그래파이트,나노탄소튜브 등)를 이용하여 전도성이 우수하면서도 초박막으로 제조가 가능하고 고 굴절 시에도 쉽게 파손되지 않고, 원가를 줄일 수 있도록 하고 대량으로 생산할 수 있고, 연속 생산에 의해 제조할 수 있고 공정효율을 높일 수 있다. One embodiment of the present invention, by using pure carbon fine particles (graphene, graphite, nano-carbon tube, etc.) is excellent in conductivity and can be manufactured in an ultra-thin film, so that it is not easy to break even at high refractive index, it is possible to reduce the cost It can be produced in large quantities, can be manufactured by continuous production, and process efficiency can be increased.

    상기 (D)단계에서 흡입한 잔류 탄소미립자에 대해 칼날이 내장된 입자분산기를 통과한 후 분산입자집합탱크로 유입되게 하고,After passing through the particle disperser built-in blade for the residual carbon fine particles sucked in the step (D), and introduced into the dispersed particle aggregation tank,
    상기 분산입자집합탱크 내에 배치된 입자분리기를 경유토록 하여 입자분산기를 통과한 분산입자로부터 비중 차이에 의해 미세입자와 응집입자를 분리시키되,The fine particles and the aggregated particles are separated from the dispersed particles passing through the particle disperser through the particle separator disposed in the dispersed particle aggregation tank by the difference in specific gravity,
    상기 비중이 낮은 미세입자는 상측방향으로 이동을 통해 공기분리탱크로 유입되게 하고, 상기 비중이 큰 응집입자는 하측 이동을 통해 입자분산기로 다시 보내 재분산되게 하며,The low specific gravity fine particles are introduced into the air separation tank by moving upward, and the high specific gravity particles are sent back to the particle disperser through the downward movement to be redispersed.
    상기 공기분리탱크로 미세입자와 함께 유입된 공기는 상측방향으로 이동을 통해 공기제거필터로 보내 제거하고, 상기 미세입자는 하측방향으로 이동을 통해 상기 (B)단계로 보내 재사용되게 하는 것을 특징으로 하는 초박막 열확산시트의 제조방법.Air introduced into the air separation tank together with the fine particles is removed by sending it to the air removal filter by moving upward, and the fine particles are sent to the step (B) by moving downward to be reused. Method for producing an ultra thin thermal diffusion sheet.
