Description

방열 전착도료 조성물{Heat dissipation electrodeposition coating composition}Heat dissipation electrodeposition coating composition

본 발명은 방열 전착도료 조성물에 관한 것이다.The present invention relates to a heat dissipation electrodeposition coating composition.

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, such as electronic devices and lighting products, the lifespan of the product is greatly affected by heat efficiency, so many efforts are being made to improve heat dissipation performance. As a measure to improve the heat dissipation performance of these products, the demand for a technology for coating the exterior of the product with a heat dissipating paint is increasing. In other words, the demand for products coated with a heat-dissipating functional paint is increasing as a method to prevent heat accumulation in the heating element and to prevent accidents such as failure, fire, and explosion due to overheating of electronic devices that generate a lot of heat.

액상도료는 용제에서 발생되는 다양한 휘발성 유기화합물들이 인체에 유해하여 아토피와 같은 피부질환이나 호흡기질환을 유발시키기도 하며, 대기도 오염시키는 단점이 있다. Liquid paints have disadvantages in 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 air.

이에 반해, 수성 전착도료는 용제를 사용하지 않기 때문에 액상도료처럼 휘발성 유기화합물이 발생되지 않아 액상도료에 비해 친환경적이고, 인체에도 유해하지 않으며, 원하는 두께의 도막을 손쉽게 얻을 수 있는 장점이 있다. 또한, 전착도료는 금속기재 표면 보호, 광택 등의 개선 목적으로도 많은 제품에 광범위한 코팅기술로 적용되고 있다.On the other hand, water-based electrodeposition paints do not use solvents, so they do not generate volatile organic compounds like liquid paints, so they are more eco-friendly than liquid paints, are not harmful to the human body, and have the advantages of easily obtaining a coating of a desired thickness. In addition, electrodeposition paint is applied to many products as a wide range of coating technology for the purpose of improving the surface protection and gloss of metal substrates.

상술한 바와 같은 도료의 특성으로 인해 최근에는 액상도료의 사용이 자제되고, 전착도료의 사용이 장려되고 있는 실정이나, 방열성 도료들은 거의 대부분 액상도료이다. 방열성을 가지는 전착도료가 몇몇 제안되기는 하였으나, 방열성이 미미하며, 일반적인 전착도료 조성에 흑연, 탄소나노튜브, 또는 그래핀 등과 같은 탄소소재를 첨가하는 방법으로 방열특성을 구현하고 있다.Due to the characteristics of paints as described above, the use of liquid paints is recently restrained and the use of electrodeposited paints is encouraged. However, most of the heat dissipating paints are liquid paints. Although some electrodeposition paints having heat dissipation properties have been proposed, heat dissipation properties are insignificant, and heat dissipation properties are realized by adding carbon materials such as graphite, carbon nanotubes, or graphene to the general electrodeposition 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 전착도료의 생산비용이 높아지는 문제점이 있다.However, when carbon materials (graphite, carbon nanotubes, graphene, etc.) are used, heat conduction and heat dissipation properties can be easily improved, but the overall color of the paint is black, so the selection is limited when applied to the exterior of various products, It cannot be converted to another color. In addition, there is a problem in that the production cost of the developed electrodeposition paint increases because the price of the carbon material used is very high.

이에, 본 발명자들은 탄소 소재를 배제한 방열 전착도료 제조 기술을 연구하던 중, 디이소시아네이트 작용기를 포함하는 가교제의 가교 사이트 일부를 비활성화시키고, 카올리나이트 및 이산화티탄을 열전도 필러로 사용할 경우, 방열 성능이 현저히 우수하되, 색상 표현의 자유도가 높은 도료를 제조할 수 있음을 알아내고 본 발명을 완성하였다.Accordingly, the present inventors inactivated a part of the crosslinking site of a crosslinking agent containing a diisocyanate functional group while researching a technology for manufacturing a heat dissipation electrodeposition coating excluding carbon materials, and using kaolinite and titanium dioxide as a heat conductive filler, the heat dissipation performance is remarkably excellent However, it was found that a paint with a high degree of freedom of color expression could be manufactured, and the present invention was completed.

한편, 탄소소재(흑연, 탄소나노튜브, 그래핀 등)를 이용한 기존의 방열 전착도료의 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 전착도료의 생산비용이 높아지는 문제점이 있다. On the other hand, in the case of conventional heat dissipation electrodeposition paints 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 The selection is limited when applied to the skin, and conversion to other colors is not possible. In addition, there is a problem in that the production cost of the developed electrodeposition paint increases because the price of the carbon material used is very high.

본 발명에 따른 방열 전착도료는 탄소소재를 사용하지 않기 때문에 기본적으로 흰색을 나타내며, 다른 색상으로 변환이 자유롭고, 원료의 가격이 상대적으로 저렴하여 생산비용이 낮은 장점이 있으므로, 기존 탄소소재를 첨가한 방열 전착도료의 문제점을 해결하여 유용하게 사용될 수 있다.Since the heat dissipation electrodeposition paint according to the present invention does not use a carbon material, it is basically white, can be freely converted to another color, and has the advantage of low production cost due to the relatively low price of raw materials. It can be usefully used by solving the problem of heat dissipation electrodeposition paint.
