Description

절연용 적층판Insulation laminate

본 명세서에 기재된 실시예는 열경화성 수지 조성물, 상기 열경화성 수지 조성물을 사용한 프리프레그 및 상기 프리프레그를 사용한 적층판에 관한 것이다.Examples described herein relate to a thermosetting resin composition, a prepreg using the thermosetting resin composition, and a laminate using the prepreg.

최근의 전력 절약을 위한 노력에 따라, LED 조명으로 대표되는 발광 다이오드를 사용한 전자 기기가 보급되고 있다. 이와 같은 발광 다이오드로는 전자 기기의 소형화·박형화의 관점에서 기판 표면에 소자를 직접 실장한 칩 LED가 증가하고 있다. LED 소자를 실장하는 기판으로는 종래부터 열경화성 수지를 함침시킨 섬유상 보강 기재의 층을 1 매 또는 복수 매 적층해서 가열 가압 성형한 적층판이 사용되고 있다. 특히, 청색·백색의 칩 LED에서는 가시광 단파장 영역의 반사가 중요하므로, 예를 들어 특허문헌 1에 개시되어 있는 열경화성 수지에 착색 안료로서 이산화티타늄 등을 함유시킨 백색 기판이 사용되고 있다.In accordance with recent efforts to save power, electronic devices using light emitting diodes typified by LED lighting have become popular. As such a light emitting diode, a chip LED in which an element is directly mounted on the surface of a substrate is increasing from the viewpoint of miniaturization and thinning of electronic devices. As a board|substrate on which an LED element is mounted, the laminated board which laminated|stacked 1 sheet or a plurality of layers of a fibrous reinforcing base material impregnated with a thermosetting resin, and heat-pressed molding is used conventionally. In particular, in blue/white chip LEDs, since reflection in a short wavelength region of visible light is important, for example, a white substrate in which titanium dioxide or the like is contained as a color pigment in a thermosetting resin disclosed in Patent Document 1 is used.

한편, 칩 LED 등의 발열을 수반하는 전자 부품을 실장하는 기판에 대해서는 종래의 기판이 방열성에 문제가 있으므로, 이와 같은 문제를 해결하기 위해 예를 들어 특허문헌 2에 개시되어 있는 부직 섬유 기재에 무기 충전재를 함유하는 열경화성 수지 조성물을 함침시킨 코어재층의 양쪽 표면에 직섬유 기재에 수지 조성물을 함침시킨 표재층을 적층하여 일체화한 컴포지트 적층판이 제안되어 있다.On the other hand, since the conventional board has a problem in heat dissipation with respect to a board on which an electronic component accompanying heat generation such as a chip LED is mounted, in order to solve such a problem, for example, the nonwoven fiber base disclosed in Patent Document 2 is inorganic A composite laminate is proposed in which a surface material layer impregnated with a resin composition is laminated on both surfaces of a core material layer impregnated with a thermosetting resin composition containing a filler to be integrated.

일본특허공개 2003-152295호 공보Japanese Patent Laid-Open No. 2003-152295 일본특허공개 2010-254807호 공보Japanese Patent Laid-Open No. 2010-254807

종래의 백색 기판에서는 안료로서 이산화티타늄 및 산화알루미늄 등을 사용하고 있기 때문에, LED 소자의 발광을 가시광 영역에서 효율적으로 반사하는 점에서는 이점이 있었다. 그러나, 열전도율이 낮기 때문에 발열을 수반하는 전자 부품의 열을 방열하기에 충분한 방열성이 얻어지지 않는 문제점이 있었다. 또한, 종래의 백색 기판에는 난연성이 부여되어 있지 않기 때문에, 안전면에서 요구되는 UL-94에서 V-0을 달성하는 것은 곤란하였다.Since titanium dioxide, aluminum oxide, etc. are used as pigments in the conventional white substrate, there was an advantage in that the light emission of the LED element was efficiently reflected in the visible light region. However, since the thermal conductivity is low, there is a problem in that sufficient heat dissipation is not obtained to dissipate the heat of the electronic component accompanying heat generation. In addition, since flame retardancy is not provided to the conventional white substrate, it was difficult to achieve V-0 in UL-94 required in terms of safety.

한편, 종래의 컴포지트 적층판은 컴포지트 구성에 의해 열전도성, 내열성, 드릴 가공성 및 난연성이 우수한 이점이 있었다. 그러나, 표재층과 코어재층으로 이루어지는 컴포지트 구성이기 때문에, 박층화하는 것이 곤란하며, 열저항의 관점에서 제약을 받는 문제가 있었다.On the other hand, the conventional composite laminate has the advantage of being excellent in thermal conductivity, heat resistance, drillability and flame retardancy due to the composite structure. However, since it is a composite structure which consists of a surface material layer and a core material layer, it is difficult to make thin layer, and there existed a problem of receiving restrictions from a viewpoint of heat resistance.

또한, 가시광 영역에서의 반사율이 낮으면서 또한 열에 의한 반사율의 저하가 크기 때문에, 칩 LED를 실장하는 경우 백색 레지스트를 도포할 필요가 있는 문제가 있었다. 또한, 코어재층에 유리 부직포를 사용하기 때문에, 두께 방향의 팽창 계수가 커서, 신뢰성이 필요한 용도에 적용하는 것이 곤란하였다.In addition, since the reflectance in the visible region is low and the decrease in the reflectance due to heat is large, there is a problem that a white resist needs to be applied when the chip LED is mounted. Moreover, since the glass nonwoven fabric is used for a core material layer, the expansion coefficient in the thickness direction is large, and it was difficult to apply to the use which requires reliability.

그래서, 본 명세서에 기재된 실시예는 상기의 점을 감안하여, 열전도성, 가시광 영역 반사율, 내변색성, 절연성, 난연성, 및 드릴 가공성 모두에서 우수하며, 또한 박층화를 가능하게 하는 적층판을 제공하는 것을 최종 목적으로 하며, 또한 이 목적을 달성하기 위한 열경화성 수지 조성물 및 프리프레그를 제공하는 것을 목적으로 한다.Therefore, the embodiment described herein is excellent in all of thermal conductivity, visible light reflectance, discoloration resistance, insulation, flame retardancy, and drillability in consideration of the above points, and also provides a laminate that enables thinning It aims to provide a thermosetting resin composition and a prepreg for achieving this object as a final object.

이하에서는 일 실시예에 따른 열경화성 수지 조성물, 프리프레그, 및 적층판에 대해 설명한다. 우선, 열경화성 수지 조성물의 일 실시예에 대해 설명한다.Hereinafter, a thermosetting resin composition, a prepreg, and a laminate according to an embodiment will be described. First, an embodiment of the thermosetting resin composition will be described.

실시예에 따르면, 열경화성 수지 조성물은 프리프레그를 형성할 때 섬유 기재에 함침시켜 사용되는 수지 조성물로서, 열경화성 수지 100질량부에 대해 100 내지 400중량부 의 무기 충전재를 함유할 수 있다. 이때, 무기 충전재는 0.1 내지 1.0㎛의 평균 입자 직경을 갖는 이산화티타늄 및 1.0 내지 20.0㎛의 평균 입자 직경을 갖는 수산화알루미늄을 함유할 수 있다. 열경화성 수지 조성물에 포함되는 열경화성 수지 및 무기 충전재의 일 실시예에 대해 이하에서 상세하게 설명한다.According to an embodiment, the thermosetting resin composition is a resin composition used by impregnating the fiber base when forming the prepreg, and may contain 100 to 400 parts by weight of an inorganic filler based on 100 parts by mass of the thermosetting resin. In this case, the inorganic filler may contain titanium dioxide having an average particle diameter of 0.1 to 1.0 μm and aluminum hydroxide having an average particle diameter of 1.0 to 20.0 μm. An embodiment of the thermosetting resin and the inorganic filler included in the thermosetting resin composition will be described in detail below.

실시예에 따르면, 열경화성 수지는 에폭시 수지, 불포화 폴리에스테르 수지, 디알릴프탈레이트 수지, 열경화성 폴리이미드 수지 등으로 구현될 수 있다. 그리고 열경화성 수지는 필요에 따라 용제 등을 첨가해서 액상으로 이용될 수 있다. 또한, 열경화성 수지에는 필요에 따라 경화제, 경화 촉진제 등의 첨가제가 첨가될 수 있다.According to an embodiment, the thermosetting resin may be implemented as an epoxy resin, an unsaturated polyester resin, a diallyl phthalate resin, a thermosetting polyimide resin, or the like. In addition, the thermosetting resin may be used in a liquid state by adding a solvent or the like as necessary.

실시예에 따라 열경화성 수지 조성물을 적층판에 사용한 경우, 이산화티타늄은 적층판에 가시광 영역에서의 높은 반사율 및 높은 열전도성을 부여할 수 있다. 실시예에 따르면, 이산화티타늄의 평균 입자 직경은 0.1 내지 1.0㎛로 구현되고, 바람직하게는 0.1 내지 0.8㎛로 구현될 수 있다. 이산화티타늄의 평균 입자 직경이 0.05㎛ 미만인 경우, 적층판의 가시광 반사율 및 열전도성이 저하될 수 있다. 또한, 이산화티타늄의 평균 입자 직경이 1.0㎛보다 큰 경우, 적층판의 가시광 반사율이 저하될 수 있다.According to the embodiment, when the thermosetting resin composition is used in a laminate, titanium dioxide can impart high reflectance and high thermal conductivity in the visible light region to the laminate. According to an embodiment, the average particle diameter of titanium dioxide may be implemented as 0.1 to 1.0 μm, preferably 0.1 to 0.8 μm. When the average particle diameter of titanium dioxide is less than 0.05 μm, the visible light reflectance and thermal conductivity of the laminate may be deteriorated. In addition, when the average particle diameter of titanium dioxide is greater than 1.0 μm, the visible light reflectance of the laminate may be lowered.

또한, 열경화성 수지 조성물을 적층판에 사용한 경우, 수산화알루미늄은 적층판의 난연성 및 열전도성을 향상시킬 수 있다. 실시예에 따르면, 수산화알루미늄의 평균 입자 직경은 1.0 내지 20.0㎛로 구현되고, 바람직하게는 1.0 내지 15.0㎛로 구현될 수 있다. 수산화알루미늄의 평균 입자 직경이 1.0㎛ 미만인 경우, 난연성 및 열전도성이 저하될 수 있다. 또한, 상기 수산화알루미늄의 평균 입자 직경이 20.0㎛보다도 큰 경우, 드릴 가공성이 저하될 수 있다.In addition, when a thermosetting resin composition is used for a laminated board, aluminum hydroxide can improve the flame retardance and thermal conductivity of a laminated board. According to an embodiment, the average particle diameter of aluminum hydroxide may be implemented as 1.0 to 20.0 μm, preferably 1.0 to 15.0 μm. When the average particle diameter of aluminum hydroxide is less than 1.0 μm, flame retardancy and thermal conductivity may be reduced. In addition, when the average particle diameter of the aluminum hydroxide is larger than 20.0㎛, drillability may be reduced.

이때, 이산화티타늄과 수산화알루미늄의 평균 입자 직경은 상술한 바와 같은 범위로 형성되되, 서로 다른 평균 입자 직경을 가질 수 있다. 이에 의해, 열경화성 수지 조성물 내에서 무기 충전재가 보다 높은 밀도로 존재하게 되어, 열경화성 수지 조성물을 적층판에 사용한 경우 우수한 내변색성 및 열전도성을 부여할 수 있다. At this time, the average particle diameters of titanium dioxide and aluminum hydroxide are formed in the same range as described above, but may have different average particle diameters. Thereby, the inorganic filler exists in a higher density in a thermosetting resin composition, and when a thermosetting resin composition is used for a laminated board, excellent discoloration resistance and thermal conductivity can be provided.

실시예에 따르면, 이산화티타늄과 수산화알루미늄의 배합비는 1:0.2 내지 1:1.5로 하고, 바람직하게는 1:0.3 내지 1:1로 할 수 있다. 이산화티타늄의 배합량 1에 대해 수산화알루미늄의 배합량이 0.2 미만인 경우, 열경화성 수지 조성물을 적층판에 사용하면 난연성 및 열전도성이 저하될 수 있다. 또한, 이산화티타늄의 배합량 1에 대해 수산화알루미늄의 배합량이 1.5를 초과하는 경우, 열경화성 수지 조성물을 적층판에 사용하면 내열성 및 내변색성이 저하될 수 있다.According to an embodiment, the mixing ratio of titanium dioxide and aluminum hydroxide may be 1:0.2 to 1:1.5, preferably 1:0.3 to 1:1. When the compounding quantity of aluminum hydroxide is less than 0.2 with respect to the compounding quantity 1 of titanium dioxide, if a thermosetting resin composition is used for a laminated board, flame retardance and thermal conductivity may fall. In addition, when the blending amount of aluminum hydroxide exceeds 1.5 with respect to the blending amount of titanium dioxide 1, heat resistance and discoloration resistance may be reduced when the thermosetting resin composition is used in a laminate.

무기 충전재로서 이산화티타늄 및 수산화알루미늄 외에도 예를 들면 산화알루미늄, 산화마그네슘 및 실리카 등의 산화물, 수산화마그네슘 등의 수산화물, 질화붕소, 질화알루미늄, 질화규소 등의 질화물, 탄화규소 및 탄화붕소 등의 탄화물 등을 더 포함할 수 있다.As inorganic fillers, in addition to titanium dioxide and aluminum hydroxide, for example, oxides such as aluminum oxide, magnesium oxide and silica, hydroxides such as magnesium hydroxide, nitrides such as boron nitride, aluminum nitride, silicon nitride, and carbides such as silicon carbide and boron carbide may include more.

열경화성 수지 조성물에 함유되는 무기 충전재의 모스 경도는 8 이하로 하는 것이 바람직하다. 무기 충전재의 모스 경도가 8을 초과하는 경우, 상기 열경화성 수지 조성물을 적층판에 사용하면 드릴 가공성이 저하될 수 있다.It is preferable that Mohs' Hardness of the inorganic filler contained in a thermosetting resin composition sets it as 8 or less. When the Mohs' Hardness of the inorganic filler exceeds 8, the use of the thermosetting resin composition for a laminate may decrease drillability.

열경화성 수지 100중량부에 대한 무기 충전재의 배합비는 100 내지 400중량부로 하고, 바람직하게는 150 내지 350중량부로 할 수 있다. 열경화성 수지 100중량부에 대한 무기 충전재의 배합비가 100중량부 미만인 경우, 열경화성 수지 조성물을 적층판에 사용하면 열전도성이 저하될 수 있고, 무기 충전재의 배합비가 400중량부를 초과하는 경우, 열경화성 수지 조성물을 사용한 적층판의 생산성이 저하될 수 있다.The mixing ratio of the inorganic filler to 100 parts by weight of the thermosetting resin is 100 to 400 parts by weight, preferably 150 to 350 parts by weight. When the compounding ratio of the inorganic filler to 100 parts by weight of the thermosetting resin is less than 100 parts by weight, when the thermosetting resin composition is used in the laminate, the thermal conductivity may decrease, and when the compounding ratio of the inorganic filler exceeds 400 parts by weight, the thermosetting resin composition The productivity of the used laminate may be lowered.

At this time, a solvent or the like may be added as needed.

The prepreg according to the embodiment may be formed by impregnating a thermosetting resin composition in a fiber base in a state of a woven fabric, a nonwoven fabric, or the like, and then drying the thermosetting resin to semi-curing the thermosetting resin.

이때, 프리프레그에 사용하는 섬유 기재의 실시예로 유리 직포 등을 들 수 있다. 또한, 섬유 기재의 섬유로는 유리 섬유, 액정 중합체 섬유, 아라미드 섬유, 카본 섬유, 폴리에스테르 섬유, 나일론 섬유, 아크릴 섬유, 및 비닐론 섬유 등이 사용될 수 있다.In this case, examples of the fiber base used for the prepreg include a glass woven fabric. In addition, as the fiber-based fiber, glass fiber, liquid crystal polymer fiber, aramid fiber, carbon fiber, polyester fiber, nylon fiber, acrylic fiber, vinylon fiber, and the like may be used.

The laminated board according to the embodiment is obtained by heat-pressing molding at a predetermined temperature and pressure by sandwiching one prepreg or a laminate of a plurality of prepregs by a metal plate serving as a heating and pressing means.

다음으로, 적층판의 하나의 형태인 금속박 부착 적층판(1)의 실시예 대해 설명한다. 금속박 부착 적층판(1)은 프리프레그(2) 1 매 또는 프리프레그를 복수 매 적층한 것의 적어도 한 표면에 금속박(3)을 배치한 후 가열 가압 성형함으로써 얻어지는 것이다. 금속박(3)은 동박, 알루미늄박 등으로 구현될 수 있다.Next, the Example of the laminated board 1 with metal foil which is one form of a laminated board is demonstrated.

금속박 부착 적층판(1)을 생성하기 위하여, 우선 섬유 기재인 유리 직포에 열경화성 수지 조성물을 함침시킨다. 그 후, 열경화성 수지 조성물을 함침시킨 유리 직포를 가열 건조함으로써, 반경화 상태의 열경화성 수지 조성물을 포함하는 프리프레그(2)를 얻는다.In order to produce the laminated board 1 with metal foil, first, the glass woven fabric which is a fiber base is impregnated with a thermosetting resin composition. Then, the prepreg 2 containing the thermosetting resin composition of a semi-hardened state is obtained by heat-drying the glass woven fabric impregnated with the thermosetting resin composition.

그 후, 상기 프리프레그(2)를 2 매 적층하며, 프리프레그(2)를 2매 적층한 것의 양면에 2 매의 금속박(3)을 각각 별도로 겹친다. 그 후, 가열 및 가압 수단인 금속판에 의해 사이에 끼워 소정의 온도 및 압력으로 가열 가압 성형하면, 도 1에 도시한 바와 같은 단면 구조의 금속박 부착 적층판(1)이 완성된다.Thereafter, the two prepregs 2 are laminated, and two metal foils 3 are respectively overlapped on both surfaces of the two prepregs 2 laminated. Thereafter, the laminated board 1 with metal foil having a cross-sectional structure as shown in FIG. 1 is completed by being sandwiched by a metal plate serving as a heating and pressurizing means and heat-pressed at a predetermined temperature and pressure.

본 실시 형태와 같이 섬유 기재로서 유리 섬유의 직포인 유리 직포를 사용함으로써 적층판은 실용 가능한 강도를 유지하면서 박층화를 달성할 수 있다. 또한, 박층화에 의해 두께 방향의 열 저항을 저감할 수 있으며, 방열성을 높일 수 있다. 상기 열 저항이란 예를 들어 JPCA 규격의 JPCA-TMC-LED02T-2010에 시험 방법이 규정되어 있는 방열 특성의 평가 방법에 의한 것을 의미한다.As in this embodiment, by using the glass woven fabric which is a woven fabric of glass fiber as a fiber base material, a laminated board can achieve thickness reduction, maintaining practical strength. Moreover, the thermal resistance in the thickness direction can be reduced by thickness reduction, and heat dissipation can be improved. The said thermal resistance means that it is based on the evaluation method of the heat dissipation characteristic whose test method is prescribed|regulated in JPCA-TMC-LED02T-2010 of JPCA standard, for example.

또한, 적층판의 다른 형태인 금속 베이스 금속박 부착 적층판(10)의 일 실시예에 대해 설명한다. 금속 베이스 금속박 부착 적층판(10)은 프리프레그(2) 1 매 또는 프리프레그(2)를 복수 매 적층한 것의 한쪽 표면에 금속박(3)을 배치하고, 다른 쪽 표면에 방열용 금속 베이스판(4)을 배치한 후 가열 가압 성형함으로써 얻어지는 것이다. 도 2에 도시하는 금속 베이스 금속박 부착 적층판(10)은 프리프레그(2)를 2 매 적층한 것의 한쪽 표면에 금속박(3)을 배치하고, 다른 쪽 표면에 방열용 금속 베이스판(4)을 배치하여, 가열 가압 성형한 것이다.In addition, an embodiment of the laminated board 10 with a metal base metal foil which is another form of a laminated board is demonstrated.

표 3을 보면 알 수 있는 바와 같이, 실시예 7과 같이 금속 베이스 금속박 부착 적층판의 절연층에 프리프레그를 사용함으로써, 비교예 7과 같은 종래 기술의 수지 시트와 비교하면 절연 파괴 전압은 동등하면서 표준 편차를 절반 이하로 저감할 수 있다. 따라서, 금속 베이스 금속박 부착 적층판의 절연층에 프리프레그를 사용함으로써, 다른 특성을 유지하면서 절연 신뢰성에서 우수한 효과를 발휘할 수 있다. As can be seen from Table 3, by using a prepreg for the insulating layer of the laminated sheet with a metal base metal foil as in Example 7, the breakdown voltage is equivalent and standard as compared with the resin sheet of the prior art as in Comparative Example 7. The deviation can be reduced to half or less. Therefore, by using a prepreg for the insulating layer of a laminated board with metal base metal foil, the effect excellent in insulation reliability can be exhibited, maintaining other characteristics.

본 명세서의 실시예에 따른 적층판은 프리프레그의 열경화성 수지 조성물의 무기 충전재로서 소정 입자의 이산화티타늄 및 수산화알루미늄을 사용함으로써 열전도성이 우수한 효과를 발휘한다. 또한, 상기 무기 충전재로서 이산화티타늄을 사용함으로써 가시광 영역 반사율에서 우수한 효과를 발휘하며, 무기 충전재를 종래보다도 높은 비율로 함으로 인한 유기 성분의 저감에 의해 내변색성이 우수한 효과를 발휘한다.The laminate according to the embodiment of the present specification exhibits excellent thermal conductivity by using predetermined particles of titanium dioxide and aluminum hydroxide as inorganic fillers of the thermosetting resin composition of the prepreg. In addition, the use of titanium dioxide as the inorganic filler exhibits an excellent effect in the visible light region reflectance, and exhibits an excellent effect of discoloration resistance by reducing the organic component due to the inorganic filler in a higher ratio than before.

그리고, 상기 무기 충전재로서 이산화티타늄을 사용하며 무기 충전재를 종래보다도 높은 비율로 함으로 인한 유기 성분의 저감에 의해 난연성이 우수한 효과를 발휘할 수 있다. 또한, 상기 무기 충전재로서 소정 입자 직경의 이산화티타늄, 수산화알루미늄 등의 저경도의 충전재를 사용함으로써, 드릴 가공성이 우수한 효과를 발휘한다. 또한, 적층판의 박층화가 가능해짐으로써 열 저항을 대폭 저감하여, 방열성이 우수한 효과를 발휘한다. 본 발명의 프리프레그는, 금속 베이스 금속박 부착 적층판의 절연층에 사용함으로써, 금속 베이스 금속박 부착 적층판의 절연 신뢰성을 향상시킬 수 있다.And, titanium dioxide is used as the inorganic filler, and the excellent effect of flame retardancy can be exhibited by reducing the organic component due to the inorganic filler being used in a higher ratio than before. Moreover, the effect excellent in drillability is exhibited by using low-hardness fillers, such as titanium dioxide and aluminum hydroxide of a predetermined particle diameter, as said inorganic filler. Moreover, since the laminated board can be made thin, thermal resistance is greatly reduced, and the effect excellent in heat dissipation is exhibited. By using the prepreg of this invention for the insulating layer of a laminated board with metal-base metal foil, the insulation reliability of a laminated board with metal-base metal foil can be improved.
