Description
본 발명은 소성 처리된 알루미늄실리케이트를 이용한 방열성 분체도료에 관한 것으로, 구체적으로 소성 처리된 알루미늄실리케이트 및 이산화티타늄, 알루미나, 이산화규소 및 탄산칼슘으로 이루어진 군으로부터 선택되는 1종을 열전도성 필러로 이용하여 제조된 방열성 분체도료에 관한 것이다.The present invention relates to a heat dissipating powder coating using sintered aluminum silicate, and specifically, using sintered aluminum silicate and one selected from the group consisting of titanium dioxide, alumina, silicon dioxide and calcium carbonate as a thermally conductive filler. It relates to the prepared heat dissipating powder coating.
전자기기 제품이나 조명 제품 등을 비롯하여 방열이 요구되는 제품은, 발열효율에 따라 제품의 수명이 많은 영향을 받기 때문에 방열성능을 높이기 위한 많은 노력이 이루어지고 있다. 이들 제품들의 방열성능을 높이기 위한 방안으로 제품의 외장을 방열성 도료로 코팅하는 기술에 대한 수요가 증가하고 있다. 다시 말해 발열체의 열 축적을 방지하고, 열이 많이 발생하는 전자기기의 과열에 의한 고장, 화재, 폭발 등의 사고를 방지하기 위한 방법으로 방열 기능성 도료를 도포하는 제품에 대한 수요가 증가하고 있다.For products requiring heat dissipation, including electronic products and lighting products, a lot of efforts have been made to increase heat dissipation performance because the life of the product is greatly affected by the heating efficiency. As a way to increase the heat dissipation performance of these products, there is an increasing demand for a technology that coats the exterior of the product with a heat dissipation paint. In other words, as a method to prevent heat accumulation of a heating element and prevent accidents such as failure, fire, and explosion due to overheating of electronic devices that generate a lot of heat, there is an increasing demand for products that apply heat-dissipating functional paints.
한편, 액상도료는 용제에서 발생되는 다양한 휘발성 유기화합물들이 인체에 유해하여 아토피와 같은 피부질환이나 호흡기질환을 유발시키기도 하며, 대기도 오염시키는 단점이 있다. 이에 반해, 분체도료는 용제를 사용하지 않기 때문에 액상도료처럼 휘발성 유기화합물이 발생되지 않아 액상도료에 비해 친환경적이며, 인체에도 유해하지 않으며. 원하는 두께의 도막을 손쉽게 얻을 수 있는 장점이 있다. 또한, 분체도료는 금속기재 표면 보호, 광택 등의 개선 목적으로도 많은 제품에 광범위한 코팅기술로 적용되고 있다.On the other hand, liquid paints have disadvantages that various volatile organic compounds generated from solvents are harmful to the human body, causing skin diseases such as atopy or respiratory diseases, and polluting the atmosphere. On the other hand, powder paints do not use solvents, so volatile organic compounds are not generated like liquid paints, so they are more environmentally friendly than liquid paints, and are not harmful to the human body. There is an advantage of being able to easily obtain a coating film of a desired thickness. In addition, powder coatings are widely applied to many products for the purpose of improving the surface protection and gloss of metal substrates.
상술한 바와 같은 도료의 특성으로 인해 최근에는 액상도료의 사용이 자제되고, 분체도료의 사용이 장려되고 있는 실정이나, 방열성 도료들은 거의 대부분 액상도료이다. 방열성을 가지는 분체도료가 몇몇 제안되기는 하였으나, 방열성이 미미하며, 일반적인 분체도료 조성에 흑연, 탄소나노튜브, 또는 그래핀 등과 같은 탄소소재를 첨가하는 방법으로 방열특성을 구현하고 있다.Due to the characteristics of the above-described paints, the use of liquid paints has been restricted in recent years, and the use of powder paints is being encouraged, but most of the heat dissipating paints are liquid paints. Although some powder paints having heat dissipation have been proposed, heat dissipation properties are insignificant, and heat dissipation properties are implemented by adding a carbon material such as graphite, carbon nanotubes, or graphene to the general powder coating composition.
그러나 탄소소재(흑연, 탄소나노튜브, 그래핀 등)를 사용하면 열전도와 방열특성은 쉽게 향상시킬 수 있으나, 전체적으로 도료의 색상이 검은색을 띄게 되어 다양한 제품의 외관에 도포시 선택이 제한적이고, 다른 색상으로 변환이 불가하다. 그리고 사용되는 탄소소재의 가격이 매우 높아 개발되는 분체도료의 생산비용이 높아지는 문제점이 있다.However, if carbon materials (graphite, carbon nanotubes, graphene, etc.) are used, the heat conduction and heat dissipation characteristics can be easily improved, but the overall color of the paint is black, so when applying to the exterior of various products, the selection is limited. It cannot be converted to other colors. In addition, the cost of the carbon material used is very high, and the production cost of the powder coating to be developed is increased.
이에, 본 발명자들은 탄소소재를 배제한 방열분체도료 제조 기술을 연구하던 중, 소성 처리된 알루미늄실리케이트(aluminum silicate)를 이용한 방열분체도료를 개발하였고, 상기 방열분체도료의 열전도 효과 및 방열 효과가 우수함을 확인하여 본 발명을 완성하였다.Accordingly, the inventors of the present invention developed a heat-dissipating powder paint using sintered aluminum silicate while researching a technology for manufacturing a heat-dissipating powder paint excluding carbon materials. Confirmed and completed the present invention.

본 발명의 일실시예에 따르면, 본 발명에 따른 방열성 분체도료는 기존 분체도료에 소성 처리된 알루미늄실리케이트를 포함시켜 제조함으로써, 소성 처리된 알루미늄실리케이트를 포함하지 않는 분체도료 또는 소성 처리되지 않은 알루미늄실리케이트를 포함시켜 제조한 분체도료 대비 분체도료를 도포한 시료의 표면 온도(T1)가 낮아지고, 방열 온도(T2)가 증가되는 효과를 나타낼 수 있다(실험예 1 참조).According to an embodiment of the present invention, the heat dissipating powder coating according to the present invention is manufactured by including a sintered aluminum silicate in an existing powder coating, so that a powder coating that does not contain the sintered aluminum silicate or an aluminum silicate that is not sintered The surface temperature (T1) of the sample coated with the powder coating is lowered and the heat dissipation temperature (T2) is increased compared to the powder coating prepared by including (see Experimental Example 1).
일반적으로, 방열 온도는 시료 표면 위 15mm 지점의 공기온도를 측정함으로써 평가하게되며, 시료의 표면 온도와 방열 온도의 온도 차이가 크다는 것은 그 시료를 통과하여 전달되는 열에너지량이 많다는 것을 의미한다(수학식 1 참조). 동일한 환경에서 열에너지가 공급되는 상황에서는 표면의 온도가 낮을수록 위 아래면의 온도차이가 크게 되므로, 시료의 열전달이 효과적임을 의미한다. 즉, 시료표면으로 동일한 열에너지가 공급되었을 때 표면의 온도가 상대적으로 낮다는 것은 시료를 통과하는 열에너지가 더 많다는 것을 의미하고 시료표면에 열에너지가 축적되지 않으며 외부(대기)로 열에너지가 잘 방출되고 있음을 의미한다. 동일한 조건에서 시료표면으로 전달되는 열에너지가 외부(대기)로 잘 방출되면 그 주변의 대기온도를 상승시키게 되어 상대적으로 높은 온도를 측정할 수 있다. 즉, 방열온도가 상대적으로 높다는 것은 시료표면으로부터 열에너지가 잘 방출되고 있음을 의미한다. In general, the heat dissipation temperature is evaluated by measuring the air temperature at a point 15 mm above the surface of the sample, and the large difference in temperature between the surface temperature of the sample and the heat dissipation temperature means that the amount of heat energy transmitted through the sample is large (Equation 1). In a situation where thermal energy is supplied in the same environment, the lower the surface temperature, the greater the difference in temperature between the top and bottom surfaces, which means that heat transfer of the sample is effective. That is, when the same heat energy is supplied to the sample surface, the relatively low temperature of the surface means that there is more heat energy passing through the sample, and thermal energy is not accumulated on the sample surface, and heat energy is well released to the outside (atmosphere). Means. If the heat energy transferred to the sample surface under the same conditions is well discharged to the outside (atmosphere), the ambient air temperature is raised, and a relatively high temperature can be measured. That is, the relatively high heat dissipation temperature means that heat energy is well released from the sample surface.
열전도 현상을 설명하는 법칙을 '열전도의 법칙' 또는 '푸리에 열전도법칙'이라고 하며, 하기 수학식 1과 같이 나타낼 수 있다(도 1 참조).The law describing the heat conduction phenomenon is referred to as the'law of heat conduction' or'the Fourier law of heat conduction', and can be expressed as
[수학식 1][Equation 1]
(λ = 물질의 열전도계수;(λ = thermal conductivity coefficient of the material;
q = 열전달에너지;q = heat transfer energy;
A = 열이 전달되는 수직방향의 면적;A = vertical area through which heat is transferred;
(∂T/∂x) = 열이 전달되는 방향으로 온도구배.)(∂T/∂x) = temperature gradient in the direction of heat transfer.)
한편, 탄소소재(흑연, 탄소나노튜브, 그래핀 등)를 이용한 기존의 방열성 분체도료의 경우, 열전도와 방열특성은 쉽게 향상시킬 수 있으나, 전체적으로 도료의 색상이 검은색을 띄게 되어 다양한 제품의 외관에 도포시 선택이 제한적이고, 다른 색상으로 변환이 불가하다. 그리고 사용되는 탄소소재의 가격이 매우 높아 개발되는 분체도료의 생산비용이 높아지는 문제점이 있다. On the other hand, in the case of existing heat dissipating powder coatings using carbon materials (graphite, carbon nanotubes, graphene, etc.), heat conduction and heat dissipation characteristics can be easily improved, but the overall color of the paint is black, so the appearance of various products When applied to, the selection is limited, and conversion to other colors is not possible. In addition, the cost of the carbon material used is very high, and the production cost of the powder coating to be developed is increased.
본 발명에 따른 상기 방열성 분체도료는 탄소소재를 사용하지 않기 때문에 기본적으로 흰색을 나타내며, 다른 색상으로 변환이 자유롭고, 원료의 가격이 상대적으로 저렴하여 생산비용이 낮은 장점이 있으므로, 기존 탄소소재를 첨가한 방열성 분체도료의 문제점을 해결하여 유용하게 사용될 수 있다.Since the heat dissipating powder coating according to the present invention does not use a carbon material, it basically exhibits white color, is free to convert to other colors, and has the advantage of low production cost due to relatively low cost of raw materials, so existing carbon materials are added. It can be usefully used by solving the problem of a heat dissipating powder coating.

예를 들어, 상기 조명등기구는 방열성 분체도료를 몸체, 반사패널 또는 히트싱크에 코팅한 후 경화시켜 제조된 것일 수 있고, LED 등일 수 있으나 이에 제한되지는 않는다. 또한, 상기 열교환기는 발전소, 선박, 정유설비, 화학플랜트, 철강산업시설, 하수정화설비 및 폐수정화설비로 이루어진 군으로부터 선택되는 1종 이상에서 사용되는 열교환기일 수 있으나, 이에 제한되지는 않는다.For example, the lighting fixture may be manufactured by coating a heat-dissipating powder paint on a body, a reflective panel, or a heat sink and then curing it, and may be an LED, but is not limited thereto. In addition, the heat exchanger may be a heat exchanger used in one or more selected from the group consisting of power plants, ships, oil refining facilities, chemical plants, steel industry facilities, sewage purification facilities, and wastewater purification facilities, but is not limited thereto.

<< 실험예Experimental example 1> 1> 방열분체도료의Heat dissipation powder coating 방열특성 분석 Heat dissipation characteristic analysis
실시예 1 내지 4 및 비교예 1 내지 8의 방열분체도료의 방열특성을 알아보기 위하여, 표면온도, 방사율, 열전도도 및 방열온도를 평가하였다.In order to examine the heat dissipation characteristics of the heat dissipating powder coatings of Examples 1 to 4 and Comparative Examples 1 to 8, surface temperature, emissivity, thermal conductivity and heat dissipation temperature were evaluated.
먼저, 도 2와 같이 상기 각 방열분체도료를 알루미늄 기판에 도포하여 시료를 준비하고, 시료를 핫플레이트 상에 올려놓고 동일한 온도(91±0.2℃)의 열을 안정화될 때까지 3~4시간 정도 가한 이후, 시료표면 온도(T1)와 시료표면 위 15mm 지점의 공기온도(방열온도, T2)를 측정하였다. 이 때, 공기흐름의 비정상적 변수를 제거하기 위해 윗 부분이 열려있는 원기둥 형태의 테프론 구조물을 시료표면상에 설치하고 내부의 공기온도를 분석하였다.First, as shown in Fig. 2, each of the heat dissipation powder coatings is applied to an aluminum substrate to prepare a sample, and the sample is placed on a hot plate and the heat at the same temperature (91±0.2°C) is stabilized for about 3 to 4 hours. After the addition, the sample surface temperature (T1) and the air temperature at a point 15 mm above the sample surface (heating temperature, T2) were measured. At this time, in order to remove abnormal variables of air flow, a cylindrical Teflon structure with an open upper part was installed on the sample surface and the internal air temperature was analyzed.

It was confirmed at a high level of about 4~5℃, and it was confirmed that the heat dissipation effect of transferring heat from the surface to the atmosphere was excellent.
실리카(이산화규소, SiO2) 및 소성 처리된 알루미늄실리케이트를 방열첨가제로 이용하여 제조된 실시예 3의 방열분체도료는 비교예 대비 열전도도가 높게 나타났고, 비교예보다 표면온도가 낮고, 방열온도도 약 4~5℃ 정도 높은 수준으로 확인되어, 표면에서 대기로 열을 전달하는 방열효과가 우수함을 확인하였다.The heat dissipation powder paint of Example 3, prepared using silica (silicon dioxide, SiO 2 ) and fired aluminum silicate as a heat dissipation additive, showed higher thermal conductivity than the comparative example, and the surface temperature was lower than that of the comparative example, and the heat dissipation temperature. It was also confirmed at a high level of about 4-5°C, and it was confirmed that the heat dissipation effect of transferring heat from the surface to the atmosphere was excellent.
이산화티타늄(TiO2) 및 소성 처리된 알루미늄실리케이트를 방열첨가제로 이용하여 제조된 실시예 4의 방열분체도료는 열전도도가 약 1W/mK 수준으로 비교예 시료들에 비해 열전달 효과가 매우 우수한 것으로 나타났고, 열방사율 역시 0.9 수준으로 확인되었으며, 비교예보다 표면온도가 낮고, 방열온도도 약 4~5℃ 정도 높은 수준으로 확인되어, 열전달 효과 뿐만 아니라 표면에서 대기로 열을 전달하는 방열효과가 가장 우수함을 확인하였다.The heat dissipation powder coating of Example 4, prepared using titanium dioxide (TiO 2 ) and calcined aluminum silicate as a heat dissipation additive, has a thermal conductivity of about 1 W/mK, showing very excellent heat transfer effect compared to the comparative samples. The heat emissivity was also confirmed to be at 0.9 level, and the surface temperature was lower than that of the comparative example, and the heat dissipation temperature was also confirmed to be at a level of about 4 to 5°C, so the heat dissipation effect of transferring heat from the surface to the atmosphere was the most. It was confirmed to be excellent.
<실험예 2> 방열분체도료의 표면 발열 상태 방열특성 분석<Experimental Example 2> Analysis of the heat dissipation characteristics of the heat dissipation powder coating surface
실시예 4의 방열분체도료와 비교예 9의 일반분체도료에 대하여, 상기 실험예 1과 같이 준비한 시료 표면을 열화상카메라 촬영하여 온도에 따른 색상차이를 확인하였다.For the heat dissipation powder coating of Example 4 and the general powder coating of Comparative Example 9, the surface of the sample prepared as in Experimental Example 1 was photographed with a thermal imaging camera to confirm the color difference according to the temperature.
도 4는 본 발명에 따른 실시예 4의 방열분체도료(오른쪽) 및 비교예 9의 일반분체도료(왼쪽)의 표면 온도를 열화상카메라로 촬영한 사진이다.4 is a photograph taken with a thermal imaging camera of the surface temperatures of the heat dissipating powder coating (right) of Example 4 and the general powder coating (left) of Comparative Example 9 according to the present invention.
그 결과, 도 4에 나타난 바와 같이, 비교예 9의 분체도료는 백색으로 나타나, 적색으로 나타난 실시예 4의 방열분체도료보다 표면 온도가 높은 것으로 확인하였다. 이는, 비교예 9의 분체도료가 발열체로부터 열을 전달 받았을 때 대기로 열을 방출 하지 못하고 시료 표면에 열을 머금고 있다는 것을 의미하며, 이와 반면에 본 발명의 실시예 4의 방열분체도료의 경우, 발열체로부터 전달받은 열을 보관하지 않고 대기로 방출시켜, 방열 특성이 우수함을 의미한다.As a result, as shown in Figure 4, the powder coating of Comparative Example 9 appeared white, it was confirmed that the surface temperature is higher than the heat dissipating powder coating of Example 4 shown in red. This means that when the powder coating of Comparative Example 9 receives heat from the heating element, it does not emit heat to the atmosphere and retains heat on the surface of the sample. , It does not store the heat received from the heating element and releases it to the atmosphere, which means excellent heat dissipation properties.
