본 발명에 따른 태양광 반사용 도막은 화이트 중도에 블랙 색상의 적외선 반사 안료를 혼합시킴으로써 기존의 태양광 반사 기능은 그대로 유지하면서 색상을 다크 그레이로 변경하여 노출에 따른 시인성을 감소시킬 수 있으므로 특히 검정색 계열의 차량에 적용하기 적합하다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar reflective coating film used in automobiles.

Description

적외선 반사 안료를 함유한 태양광 반사 도막 {Paint coat for reflecting solar light comprising infrared-reflecting pigments}Paint coat for reflecting solar light comprising infrared-reflecting pigments}

본 발명은 자동차 등 차량에 도포하여 도막 박리시 잘 드러나지 않아 상품성을 높일 수 있는 태양광 반사 도막에 관한 것이다. The present invention relates to a solar reflective coating film that can be applied to a vehicle such as an automobile so that it is hard to be exposed when the coating film is peeled off, thereby increasing the commerciality.

최근 이슈화되는 CO2 저감 대책의 일환으로 자동차용 도료에 태양광 반사 기능을 부여하여 차량 내부로 열이 유입되는 것을 방지함으로써 에어컨 사용에 따른 연료 소비량을 줄이려는 기술에 대해 활발한 연구가 진행되고 있다. 특히, 태양광에 의한 열 발생이 많은 블랙 색상의 경우 일반 도료의 경우에는 베이스층 내의 카본 블랙 안료에 의한 적외선 흡수로 온도 상승이 큰데(도 1), 베이스층에 태양광을 투과시키는 안료를 적용하고 중도에 TiO2를 함유한 화이트 색상을 적용하여 태양광을 반사시킴으로써 온도 상승을 감소시키는 기술이 연구되고 있다. (도 2) As part of the recent CO 2 reduction measures, active research is being conducted on technologies to reduce fuel consumption by using air conditioners by providing solar reflection function to automotive paints to prevent heat from flowing into the vehicle. In particular, in the case of the black color that generates a lot of heat generated by sunlight, the temperature rise is large due to infrared absorption by the carbon black pigment in the base layer in the case of general paints (FIG. 1). In the middle, a technique of reducing temperature rise by reflecting sunlight by applying a white color containing TiO 2 is being studied. (Fig. 2)

그러나, 필드 환경에서 차량 선단부에 치핑(chipping)이나 충격에 의하여 도막 박리될 경우 화이트 중도가 외부로 그대로 노출되어 쉽게 박리부가 눈에 보이므로 차량 상품성을 저하시키는 원인이 된다. However, in the field environment, when the coating film is peeled off due to chipping or impact on the tip of the vehicle, the white midway is exposed to the outside and the peeling part is easily visible.

따라서 블랙 색상과 같이 어두운 색상의 차량의 경우에 있어서는 이와 같이 중도의 색상이 쉽게 노출되지 않도록 할 필요성이 크다.  Therefore, in the case of a dark-colored vehicle, such as a black color, there is a great need to prevent such intermediate colors from being easily exposed.

이에 본 발명자들은 상기의 종래기술의 문제점을 해결하기 위하여 연구 노력한 결과, 화이트 중도에 블랙 색상의 적외선 반사 안료를 혼합시킴으로써 기존의 태양광 반사 기능은 그대로 유지하면서 색상을 다크 그레이로 변경하여 노출에 따른 시인성을 감소시킬 수 있음을 발견하여 본 발명을 완성하였다. Accordingly, the present inventors have studied to solve the problems of the prior art, by mixing the infrared reflecting pigment of the black color in the middle of the white by changing the color to dark gray while maintaining the existing solar reflection function as the exposure The present invention has been completed by discovering that visibility can be reduced.

따라서 본 발명의 목적은 도장 외관, 부착성, 내충격성, 내수성 등의 기존 물성은 그대로 유지하면서 치핑이나 충격에 의한 박리시 노출에 따른 시인성을 감소시킬 수 있는 태양광 반사용 도막을 제공하는 것이다. Accordingly, an object of the present invention is to provide a solar reflective coating film which can reduce the visibility of exposure during chipping or impact while maintaining existing physical properties such as coating appearance, adhesion, impact resistance, and water resistance.

상기 목적을 달성하기 위한 본 발명은The present invention for achieving the above object

중도층, 베이스층 및 클리어층의 순서로 적층된 태양광 반사용 도막에 있어서, 상기 중도층에 산화철계 안료를 포함하는 것을 특징으로 하는 태양광 반사용 도막을 제공한다.In the solar reflection coating film laminated | stacked in order of the intermediate | middle layer, a base layer, and a clear layer, it provides the solar reflection coating film characterized by including an iron oxide type pigment in the said intermediate layer.

본 발명에 따른 태양광 반사용 도막은 기존 화이트 중도의 메인 수지를 변경하지 않고도 사용가능하며, 완성 도막의 태양광 반사율이 기존의 도막과 동등 수준으로 유지될 수 있는 동시에 치핑 및 외부 충격에 의한 도막 박리시 다크 그레이 색상이 중도에 노출되므로 시인성이 저감되어 상품성이 향상될 수 있다.
The solar reflective coating according to the present invention can be used without changing the main resin of the existing white midway, and the solar reflectance of the finished coating can be maintained at the same level as the existing coating, and at the same time the coating by chipping and external impact When peeling, since the dark gray color is exposed to the middle, the visibility may be reduced, and thus the merchandise may be improved.

이하, 본 발명을 좀 더 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명에 따른 태양광 반사용 도막은 중도층, 베이스층 및 클리어층의 순서로 적층되어 있으며, 상기 중도층에 산화철계 안료를 포함하는 것을 특징으로 한다.

(도 3)Iron oxide-based solar reflective pigments have a black color and have the property of reflecting infrared rays (IR) in sunlight. If a small amount of this iron oxide pigment is added in the middle of white, the color can be changed to dark gray while maintaining the solar reflection function. (Fig. 3)

본 발명에 있어서 상기 산화철계 안료는 중도 조성물 전체에 대하여 1 내지 3 중량%의 범위로 포함되는 것이 바람직하며, 더욱 바람직하게는 1.5 내지 2.5 중량%이다. 상기 범위를 벗어나 너무 적게 사용되면 다크 그레이 색상이 미발현되어 시인성 감소 효과가 적고, 너무 많이 사용되면 태양광 반사율 저하 효과가 적다. In the present invention, the iron oxide pigment is preferably included in the range of 1 to 3% by weight, more preferably 1.5 to 2.5% by weight, based on the entire intermediate composition. When used too little outside the above range, the dark gray color is not expressed, so the visibility reduction effect is small, and when used too much, the effect of lowering the solar reflectance is less.

본 발명에 있어서, 상기 조성물에는 자동차용 도료에 사용되는 일반적인 첨가제, 예를 들어 경화제, 핀홀 방지제, 흐름방지제 및 표면조정제로 이루어진 군에서 선택된 1종 이상이 추가로 포함될 수 있다.
In the present invention, the composition may further include at least one member selected from the group consisting of general additives used in automotive paints, for example, hardeners, pinhole inhibitors, flow inhibitors and surface conditioners.

상기 희석제는 경화제로는 도료를 경화시키는 역할을 하며, 구체적인 예로는 멜라민 수지, 이소시아네이트 수지 등을 사용할 수있으나, 반드시 이에 한정하는 것은 아니다. The diluent serves to cure the paint as a curing agent, and specific examples thereof may include melamine resin, isocyanate resin, and the like, but are not limited thereto.

또한, 핀홀 방지제는 도료에 핀홀이 발생하는 것을 방지하는 역할을 하며, 구체적인 예로는 아크릴계 코폴리머를 사용할 수 있다. 그 함량은 도료 조성물에 대하여 0.2~1.2 중량%의 범위로 사용되는 것이 바람직하다. In addition, the pinhole inhibitor serves to prevent the occurrence of pinholes in the paint, and specific examples thereof may use an acrylic copolymer. The content is preferably used in the range of 0.2 to 1.2% by weight based on the coating composition.

또한, 흐름방지제는 도료의 흐름을 방지하는 역할을 하며, 구체적인 예로는 아크릴계 유도체를 들 수 있다. 그 함량은 도료 조성물에 대하여 0.1~1.0 중량%의 범위로 사용되는 것이 바람직하다. In addition, the flow inhibitor serves to prevent the flow of the paint, and specific examples thereof include acrylic derivatives. The content is preferably used in the range of 0.1 to 1.0% by weight based on the coating composition.

또한, 표면조정제는 도료의 평활성을 향상시키는 역할을 하며, 구체적인 예로는 실리콘계 변성 아크릴을 예로 들 수 있다. 그 함량은 도료 조성물에 대하여 0.2~1.2 중량%의 범위로 사용되는 것이 바람직하다. In addition, the surface modifier serves to improve the smoothness of the paint, specific examples thereof include silicone-based modified acrylic. The content is preferably used in the range of 0.2 to 1.2% by weight based on the coating composition.

또한, 도료 조성물에는 자동차용 도료에 사용되는 일반적인 용제를 사용할 수 있다. 용제의 구체적인 탄화수소계, 알코올계, 에스테르계를 들 수 있다. In addition, the general composition used for the automotive coating can be used for a coating composition. Specific hydrocarbon type, alcohol type, and ester type of the solvent may be mentioned.

또한, 본 발명에 사용되는 안료의 종류로는 체질 안료로서 BaSO4를 사용할 수 있고 화이트 안료로서 TiO2를 사용할 수 있으며, 블랙 안료로서 카본블랙을 사용할 수 있다. 상기 블랙안료는 베이스층에 사용되어 적외선을 흡수하는 성질이 있으나, 중도층에 사용된 TiO2와 산화철계 안료에 의하여 적외선을 반사하게 된다. 산화철계 안료는 블랙색상에 가까우나 적외선을 반사하는 특성을 갖는 물질이다. 이러한 산화철계 안료의 구체적인 제품명으로는 BASF사의 SICOPAL BLACK K 0095, K0090 등을 들 수 있다.
In addition, as the type of pigment used in the present invention, BaSO 4 may be used as a sieving pigment, TiO 2 may be used as a white pigment, and carbon black may be used as a black pigment. The black pigment is used in the base layer to absorb infrared rays, but reflects the infrared rays by the TiO2 and iron oxide pigments used in the intermediate layer. Iron oxide pigments are materials that are close to black but reflect infrared light. Specific product names of such iron oxide pigments include SICOPAL BLACK K 0095 and K0090 manufactured by BASF.

상기 표 2의 결과를 통해 알 수 있는 바와 같이, 본 발명에 따른 일반적인 물성에 있어 종래의 화이트 안료(TiO2)만을 중도 안료로서 사용한 것과 차이가 없음을 알 수 있다. 아울러 본 발명에 따른 태양광 반사용 도막은 중도층에 화이트 안료만이 아닌 산화철계 태양광 반사 안료를 혼합함으로써 치핑시 시안성이 적어지는 것을 기대할 수 있다. 따라서 이에 따라 상품성을 향상시킬 수 있는 장점이 있다.
As can be seen from the results of Table 2, it can be seen that in the general physical properties according to the present invention, only the conventional white pigment (TiO 2) is used as the intermediate pigment. In addition, the solar reflective coating according to the present invention can be expected to be less cyan when chipping by mixing the iron oxide-based solar reflective pigments in addition to the white pigment in the intermediate layer. Therefore, there is an advantage that can be improved accordingly.
