그리고 본 발명에서 사용하는 실리콘수지는 메틸페닐폴리실록산수지 에멀젼 상태로서, 도막에 내열성 및 내식성의 특성을 부여하는 작용을 하고, 정제수 100 중량부에 대하여 320~350 중량부를 혼합하는 것이 바람직하다. 실리콘수지의 혼합량이 320 중량부 미만이 될 경우에는 도막의 내열성 및 내식성이 저하할 우려가 있고, 실리콘수지의 혼합량이 350 중량부를 초과할 경우에는 상대적으로 다른 구성성분들의 혼합량 부족으로 인해 도막의 기타 다른 기계적 물성 등이 저하할 우려가 있다. In addition, the silicone resin used in the present invention is a methylphenylpolysiloxane resin emulsion, which acts to impart heat resistance and corrosion resistance to the coating film, and is preferably mixed at 320 to 350 parts by weight based on 100 parts by weight of purified water. If the blending amount of silicone resin is less than 320 parts by weight, the heat resistance and corrosion resistance of the coating film may be lowered. If the blending amount of silicone resin is more than 350 parts by weight, the amount of the other components in the coating film may be relatively low. There is a possibility that other mechanical properties and the like will be lowered.
상기 메틸페닐폴리실록산수지 에멀젼은 정제수와 잘 혼합될 수 있도록 용제인 크실렌과 물에 현탁시킨 수지를 사용하는 것이 바람직하며, 메틸페닐폴리실록산수지 에멀젼의 조성비는 메틸페닐폴리실록산수지 45~55 중량%, 크실렌 10~15 중량%, 물 35~40 중량%으로 이루어지는 것이 바람직하다.

In the present invention, talc is a filler that functions to improve heat resistance together with the mechanical properties of the coating film, and the mixing amount of talc is preferably 45 to 50 parts by weight based on 100 parts by weight of purified water. If the mixing amount of talc is less than 45 parts by weight, the mechanical properties and heat resistance of the coating film may be lowered. If the mixing amount of talc exceeds 50 parts by weight, the other components of the coating film may be deteriorated due to the insufficient mixing of other components. There is a possibility that the physical properties and the like decrease.
또한 본 발명에서 카본블랙은 도막의 색상을 흑색으로 나타내고, 충진제들간의 공극을 메워 내식성을 향상시키는 작용을 하며, 카본블랙의 혼합량은 정제수 100 중량부에 대하여 75~85 중량부인 것이 바람직하다. 카본블랙의 혼합량이 75 중량부 미만이 될 경우에는 도막의 채도가 낮아지거나 또는 내식성이 저하할 우려가 있고, 카본블랙의 혼합량이 85 중량부를 초과할 경우에는 상대적으로 다른 구성성분들의 혼합량 부족으로 인해 도막의 기타 다른 물성 등이 저하할 우려가 있다. In addition, in the present invention, the carbon black shows the color of the coating film in black, fills the voids between the fillers to improve the corrosion resistance, and the mixing amount of the carbon black is preferably 75 to 85 parts by weight based on 100 parts by weight of purified water. If the blending amount of carbon black is less than 75 parts by weight, the saturation of the coating film may be lowered or the corrosion resistance may be lowered. If the blending amount of the carbon black is more than 85 parts by weight, the amount of carbon black may be relatively low due to the insufficient mixing amount of other components. Other physical properties of the coating film may be lowered.
그리고 상기 실리카는 도료 조성물의 흐름성 개선과 충진재의 입자 안정성을 부여하기 위한 무정형의 이산화규소인 퓸드실리카(fumed silica)로서, 기본입자가 구형의 기본입자의 평균직경이 7~40nm의 크기인 극히 작고 구형의 형태이며 넓은 표면적과 특유의 표면특성을 갖는 화합물이다. 실리카의 혼합량은 정제수 100 중량부에 대하여 8~10 중량부인 것이 바람직하다. 실리카의 혼합량이 8 중량부 미만이 될 경우에는 도료 조성물의 흐름성 개선과 충진재의 입자 안정성이 저하할 우려가 있고, 실리카의 혼합량이 10 중량부를 초과할 경우에는 도리어 도료 조성물의 흐름성이 저하하여 작업성이 떨어질 우려가 있다. The silica is fumed silica, which is amorphous silicon dioxide for improving flowability of the coating composition and imparting particle stability of the filler, wherein the primary particles have a size of 7-40 nm in average diameter of the spherical primary particles. It is a very small, spherical shape with a large surface area and unique surface properties. It is preferable that the mixture amount of silica is 8-10 weight part with respect to 100 weight part of purified water. When the mixed amount of silica is less than 8 parts by weight, the flowability of the coating composition and the particle stability of the filler may decrease. When the mixed amount of silica exceeds 10 parts by weight, the flowability of the coating composition is lowered. There is a fear that the workability is reduced.

If the amount of the dispersant is less than 18 parts by weight, the filler or pigment particles in the coating composition may not be uniformly dispersed. If the amount of the dispersant is more than 20 parts by weight, the filler may be mixed in the coating composition due to excessive mixing of the dispersant. There is a risk of sinking easily.
상기 분산제는 노닐페놀 엑소실레이트(nonylphenol ethoxylates)인 것이 바람직하다. The dispersant is preferably nonylphenol ethoxylates.
본 발명에서 상기 안정화제는 도막의 열 안전성의 물성을 향상시키는 작용을 하며, 안정화제의 혼합량은 정제수 100 중량부에 대하여 30~35 중량부인 것이 바람직하다. 안정화제의 혼합량이 30 중량부 미만인 경우에는 도막의 열 안정성이 저하할 우려가 있고, 안정화제의 혼합량이 35 중량부를 초과할 경우에는 도막의 열 안정성이 특별히 현저하게 향상되지는 않는다. In the present invention, the stabilizer serves to improve the physical properties of the thermal stability of the coating film, the amount of the stabilizer is preferably 30 to 35 parts by weight based on 100 parts by weight of purified water. When the mixing amount of the stabilizer is less than 30 parts by weight, the thermal stability of the coating film may be lowered. When the mixing amount of the stabilizer exceeds 35 parts by weight, the thermal stability of the coating film is not particularly remarkably improved.
본 발명에서 사용하는 안정화제는 염기성 아연 오르토인산염 수화물인 것이 바람직하다. It is preferable that the stabilizer used by this invention is basic zinc orthophosphate hydrate.

또한 코팅작업은 보통 표준 공기 분무 장비를 사용하여 형성시킨 25~30 ㎛의 두께(건조기준)로 여러 번 중첩하여 분무한 다음 배기가 잘되는 경화로에서 건조와 경화를 시킨다, 완전 건조 및 경화된 도막은 250℃의 온도로 30~60 분간 열을 가하여 코팅 피막층을 경화시킨다. In addition, the coating is sprayed several times with a thickness of 25 to 30 μm (dry basis), which is usually formed using a standard air spray equipment, and then dried and cured in a well ventilated curing furnace. The coating film layer is cured by applying heat at a temperature of 250 ° C. for 30 to 60 minutes.
따라서, 본 발명에 따른 흑색 수성도료 조성물은 내식성 및 내열성의 특성이 우수하여 자동차 브레이크용 디스크, 켈리퍼 또는 머플러 등과 같이 고온의 열을 직접적으로 받는 부품의 도장에 적합하다.

2. 시험편 제작2. Test piece production
상기 실시예 1, 2 및 비교예 1, 2의 조성물을 교반기를 사용하여 가볍게 교반시켜 고형분을 조성물 내에 균질화시킨 다음 강판 시험편(60×80×1.0mm)을 제작하고, 이 강판 시험편으로부터 20 cm의 거리를 두고 스프레이 건을 사용하여 25~30 ㎛의 두께(건조기준)로 두 번 분사하여 건조도막의 두께가 50~60 ㎛가 되도록 코팅 피막층을 형성시킨 다음 경화로에서 250℃의 온도로 30 분간 열을 가하여 코팅 피막층을 경화시켜 시험편을 제작하였다. The compositions of Examples 1 and 2 and Comparative Examples 1 and 2 were gently stirred using a stirrer to homogenize solids in the composition, and then a steel sheet test piece (60 × 80 × 1.0 mm) was produced, and 20 cm from the steel plate test piece. Using a spray gun at a distance, spray twice with a thickness of 25 to 30 µm (dry basis) to form a coating film layer so that the thickness of the dry coating becomes 50 to 60 µm. The test film was produced by hardening a coating film layer by applying heat.
3. 흑색 수성도료 조성물의 평가3. Evaluation of Black Water-Based Paint Composition
상기 2의 방법에 따라 제작한 시험편을 사용하여 내식성과 내열성을 시험한 결과는 아래 [표 2]의 내용과 같다. The test results of the corrosion resistance and heat resistance using the test piece produced according to the method of 2 is as shown in Table 2 below.
(레이팅넘버RN)Corrosion Resistance 1)
(Rating Number RN)
주 1) 시편 도장후 염수분무시험기(5%염화나트륨수용액)에서 1,000시간 경과 후 상태를 관찰함 Note 1) After application of the specimen, observe the condition after 1,000 hours in the salt spray tester (5% sodium chloride solution).
2) 시편 도장후 300℃의 열풍건조로에서 1시간 동안 내열처리하고 상온 냉각후 염수분무시험기(5%염화나트륨수용액)에서 1,000시간 경과 후 상태를 관찰함 2) After coating the specimens, heat-resistant for 1 hour in a hot air drying furnace at 300 ° C and observe the state after 1,000 hours in a salt spray tester (5% aqueous sodium chloride solution) after cooling to room temperature.
상기 [표 2]의 내용에 의하면, 본 발명에 따른 실시예 1, 2의 조성물을 사용하여 코팅시킨 시험편은 비교예 1, 2의 시험편에 비해 내식성 및 내열성의 성능 평가에서 모두 우수한 것으로 평가되었다. According to the contents of Table 2, the test pieces coated with the compositions of Examples 1 and 2 according to the present invention were evaluated to be superior in performance evaluation of both corrosion resistance and heat resistance compared to the test pieces of Comparative Examples 1 and 2.
상기에서 비교예 1, 2의 경우에는 퓸드실리카 또는 분산제를 첨가하지 않고 흑색 수성도료 조성물을 제조함에 따라 조성물 내의 고형분이 균일하게 분산되지 않거나 또는 도막 작업의 흐름성이 떨어져 도막의 치밀성이 저하됨에 따라 내식성 및 내열성이 실시예 1, 2에 비해 떨어지는 것으로 추정된다.In the case of Comparative Examples 1 and 2, since the black aqueous coating composition is prepared without adding fumed silica or dispersing agent, the solid content in the composition is not uniformly dispersed or the flowability of the coating work is lowered, thereby decreasing the compactness of the coating film. Therefore, it is estimated that corrosion resistance and heat resistance are inferior compared with Example 1, 2.
상술한 바와 같은, 본 발명의 바람직한 실시예에 따른 흑색 수성도료 조성물을 설명하였지만, 이는 예를 들어 설명한 것에 불과하며 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 다양한 변화 및 변경이 가능하다는 것을 이 분야의 통상적인 기술자들은 잘 이해할 수 있을 것이다.As described above, the black water-based coating composition according to a preferred embodiment of the present invention has been described, but this is merely described, for example, and various changes and modifications can be made without departing from the technical spirit of the present invention. Those skilled in the art will appreciate.
