More specifically, it is possible to use the polyether to uniformly arrange the nonuniform arrangement of aluminum particles that can appear in the coating of the base coat containing aluminum particles, thereby making it possible to take advantage of the characteristics of the metallic color, Drying type basecoat paint composition capable of preventing the coating operation in advance.
승용차 및 상용차는 다양한 환경에서 장시간 운행되는 이동용 설비이므로 차량의 내구성, 안정성, 유지 관리 및 미감의 측면에서 도장 품질이 매우 중요하다.Since passenger cars and commercial vehicles are portable equipment that is operated for a long time in various environments, quality of painting is very important in terms of durability, stability, maintenance and beauty of the vehicle.
승용차 및 상용차의 보수 도장 공정 중에서 차체 외판에 적용되는 도장 작업은 하도 도장, 퍼티 도장, 중도 도장, 상도 도장(색도료, 투명)의 순서로 진행되는데, 각 공정에 있어서 하도 도료, 퍼티, 중도 도료의 건조 시간은 대략 20℃ 기준으로 30분 정도 소요되는 것이 일반적이며 우레탄 상도 도료는 60℃ 기준으로 30분 정도 소요되는 것이 일반적이다. During the repair process of passenger cars and commercial vehicles, the painting work applied to the outer shell of the car body is carried out in the order of undercoating, putty painting, middle painting, top painting (color paint, transparent). In each process, undercoating, putty, Drying time is generally about 30 minutes at 20 ° C, and urethane top coat usually takes about 30 minutes at 60 ° C.
보통 베이스코트 도료의 도장은 은폐력과 알루미늄 입자의 균일성을 위해 2~4회에 걸쳐 도장을 하는데, 1회 도장은 날리는 듯한 스프레이 방법으로 얇게 도장하며, 두 번째 도장은 밑에 중도층의 은폐가 충분히 이루어질 수 있도록 1회에 비해 두껍게 도장을 실시한다. 마지막 3~4회의 경우 알루미늄 입자감을 살리기 위해 다시 날리듯이 얇게 스프레이 도장을 하여 마무리한다. 자동차 보수 도장 공정 중 베이스코트 색도료의 도장은 자동차 외관 색상을 나타내는 것이기에 가장 중요한 공정이라 할 수 있는데 그럼에도 불구하고 최근 신차 칼라가 다양화됨에 따라 알루미늄 입자의 불균일한 배열(메탈릭 얼룩)이 자주 발생하고 있는 것이 현실이다.Usually, the coating of the base coat paint is painted 2 ~ 4 times for the cohesive force and the uniformity of the aluminum particles, the one coat is thinly coated by the spraying method like the blowing, and the second coat is sufficient for covering the middle layer The coating should be thicker than one time so that it can be done. In the last 3 ~ 4 times, spray paint thinly as it is sprayed back to save the aluminum texture. The coating of the base coat color paint during the automobile repair painting process is the most important process because it represents the color of the exterior of the vehicle. Nevertheless, as the color of the new car has diversified recently, uneven arrangement of the aluminum particles (metallic stain) It is reality that there is.
본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위해 창안된 것으로서, 종래의 1액형 자연건조형 베이스코트 도료의 문제점인 알루미늄 입자의 불균일한 배열로 생기는 얼룩 문제를 해결하여 재작업의 불필요함을 미연에 방지하고 다양한 칼라를 구현할 수 있는 1액형 자연건조형 베이스코트 도료 조성물을 제공하는 것을 기술적 과제로 한다.Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to solve the problem of uneven arrangement of aluminum particles, which is a problem of the conventional one- And which is capable of realizing a variety of colors by preventing the uncoated base coat coating composition from being dried.

본 발명의 1액형 자연건조형 베이스코트 도료 조성물은 자동차 및 각종 차량 내외부에 적용되는 것을 특징으로 한다.The one-pack type natural-drying type base coat paint composition of the present invention is characterized in that it is applied to the interior of automobiles and various vehicles.
다음으로, 각 성분을 상기와 같이 제한한 이유에 대해 설명한다(베이스코트 원색과 베이스코트 조정용 투명을 50 : 50의 중량비로 혼합한 배합기준).Next, the reason why the respective components are limited as described above will be explained (based on the mixing ratio of 50: 50 weight ratio of base coat primary color and transparency for base coat adjustment).
상기 폴리에테르는 베이스코트 원색에 알루미늄 페이스트를 고르게 분산시켜주는 보조수지 중의 하나로서 1중량% 미만으로 첨가되면 효과가 떨어지고, 또한 5중량%를 초과하여 첨가하면 최종 도료의 도막물성이 저하되기 때문에 상기 범위로 함유되는 것이 바람직하다.The polyether is one of the auxiliary resins for uniformly dispersing the aluminum paste in the base coat primary color. If it is added in an amount of less than 1% by weight, the effect is lowered. If the content is more than 5% by weight, By weight.
상기 분자량 25,000~35,000인 CAB(Cellulose acetate butyrate)는 베이스코트 원색과 베이스코트 조정용 투명 성분의 주성분 수지 중 하나이다.The above-mentioned CAB (Cellulose acetate butyrate) having a molecular weight of 25,000 to 35,000 is one of the main component resins of the base coat primary color and the base coat adjusting transparent component.
상기 CAB가 베이스코트 원색에 8중량% 미만으로 첨가되면 안료의 분산력이 저하되고 베이스코트 원색의 저장안정성에 문제가 생길 수 있다. 또한 20중량%를 초과하여 첨가하면 안료의 함량을 적절하게 적용하지 못하는 문제가 생기며 최종 도료의 색감이 떨어지는 문제가 발생한다. 따라서 전술한 범위로 함유되는 것이 바람직하다.When the CAB is added in an amount of less than 8% by weight based on the base coat primary color, the dispersing power of the pigment may be lowered and the storage stability of the base coat primary color may be problematic. If it is added in an amount exceeding 20% by weight, a problem arises in that the content of the pigment can not be appropriately applied, and the color of the final paint is deteriorated. Therefore, it is preferable that it is contained in the above-mentioned range.
베이스코트 조정용 투명의 경우 분자량 25,000~35,000인 CAB(Cellulose acetate butyrate) 함량을 5중량% 미만으로 할 경우 베이스코트 위에 투명도료 도장 시 도막이 녹을 위험이 존재하며, 15중량% 이상 첨가할 경우 최종 도료의 색감이 떨어지는 문제가 발생할 수 있다. 따라서 전술한 범위로 함유되는 것이 바람직하다.When the content of CAB (Cellulose acetate butyrate) having a molecular weight of 25,000 to 35,000 is less than 5% by weight in the case of transparent base coat adjusting, there is a risk of the coating film being melted when the transparent coating is applied on the base coat. There may be a problem that the color tone is lowered. Therefore, it is preferable that it is contained in the above-mentioned range.
분자량 60,000~70,000인 CAB(Cellulose acetate butyrate)는 베이스코트 조정용 투명에 적용되는 수지로 10중량% 이하로 적용되면 베이스코트 위에 투명도료 도장 시 도막이 녹을 위험이 존재하며, 20중량% 이상 첨가할 경우 최종 도료의 색감이 떨어지는 문제가 발생할 수 있으므로, 전술한 범위로 함유되는 것이 바람직하다.CAB (Cellulose acetate butyrate) with a molecular weight of 60,000 ~ 70,000 is applied to transparent coating for base coat adjustment. When it is applied in 10% by weight or less, there is a risk of rusting the coating film when the transparent coating is applied on the base coat. It may cause a problem that the color of the coating material is lowered. Therefore, it is preferable that the coating material is contained in the above-mentioned range.
조정용 투명에서 CAB의 종류를 두 가지로 적용하는 까닭은 분자량 25,000~35,000인 CAB(Cellulose acetate butyrate)의 경우 분자량 60,000~70,000인 CAB(Cellulose acetate butyrate)에 비해 안료의 분산력은 떨어지지만 점도가 낮아 점도 조절이 용이하고, 분자량 60,000~70,000인 CAB(Cellulose acetate butyrate)의 경우 알루미늄 입자의 배열 및 안료의 분산력은 뛰어나지만 점도가 높아 점도 조절이 용이하지 못한 단점을 가지고 있다. 그렇기 때문에 이 두 가지 원료를 혼합하여 사용하는 것이 베이스코트 도료 조성물을 구성하는 데 최적의 조건이므로 상기 범위로 첨가하여 사용 하는 것이다.Two types of CABs are used in adjusting transparency: CAB (Cellulose acetate butyrate) with a molecular weight of 25,000 to 35,000 has a lower dispersing power than CAB (Cellulose acetate butyrate) having a molecular weight of 60,000 to 70,000, In the case of CAB (Cellulose acetate butyrate) having a molecular weight of 60,000 ~ 70,000, it is easy to control and has a disadvantage in that it is difficult to control the viscosity because of high viscosity and high dispersion power of aluminum particles and pigment. Therefore, the use of a mixture of the two raw materials is an optimal condition for forming the base coat paint composition, and therefore, the additive is added in the above range.

When added in an amount of less than 15% by weight based on the base coat color, the color spontaneity and the dispersing power of the pigment are poor. When the pigment is added in an amount exceeding 25% by weight, the hardness of the coating increases and the physical properties thereof deteriorate. In addition, when the base coat is transparent for adjusting the base coat, if it is added in an amount of less than 15% by weight, the hardness and adhesion of the coating film are lowered, and if it is added by 25% by weight or more, Therefore, it should be included in the above-mentioned range.
상기 멜라민 수지는 베이스코트 조정용 투명 성분의 보조수지 중의 하나로서 가열건조 시 폴리에스테르 수지와 경화반응을 일으키며, 1중량% 미만으로 첨가하면 도료의 경화반응성이 떨어지며, 5중량% 이상 첨가되면 도료의 건조속도가 느려지기 때문에 상기 범위로 함유되는 것이 바람직하다.The melamine resin is one of the auxiliary resins of the transparent component for adjusting the base coat, and causes a curing reaction with the polyester resin during heating and drying. When the content is less than 1% by weight, the curing reaction of the paint is poor. It is preferably contained in the above range because the speed is slowed.
상기 아미노 수지는 베이스코트 조정용 투명 성분의 하나로서 1중량% 미만으로 첨가되면 도막의 경도가 떨어지며, 5중량%를 초과하여 첨가되면 도막 물성이 저하되기 때문에 상기 범위로 함유되는 것이 바람직하다. When the amino resin is added in an amount of less than 1% by weight as a transparent component for adjusting the base coat, the hardness of the coating film is lowered. If the amino resin is added in an amount exceeding 5% by weight, physical properties of the coating film are lowered.
상기 아크릴 수지는 베이스코트 조정용 투명 성분의 하나로서, 5중량% 미만으로 첨가되면 도막의 건조속도가 저하되며, 10중량% 이상 첨가되면 도막외관 등이 저하되기 때문에 상기 범위로 함유되는 것이 바람직하다.If the amount of the acrylic resin is less than 5% by weight, the drying speed of the coating film is lowered. If the amount of the acrylic resin is more than 10% by weight, the appearance of the coating film is deteriorated.
상기 폴리아마이드 왁스는 안료의 침전, 알루미늄 입자의 침강성 및 배열을 잡아주는 원료로서 베이스코트 원색에서 1중량% 미만이면 안료 및 알루미늄 입자의 침강안정성이 떨어지며, 5중량%를 초과하면 상도도료와의 부착성 문제가 나타날 수 있기 때문에 전술한 범위로 함유되는 것이 바람직하다. 또한 베이스코트 조정용 투명에서도 1중량% 미만으로 첨가하게 되면 최종도료의 알루미늄 입자와 안료의 침강안정성이 떨어지며, 5중량% 이상 첨가하게 되면 위와 마찬가지로 상도도료와의 부착성 문제가 나타날 수 있기 때문에 전술한 범위로 함유되는 것이 바람직하다.The polyamide wax is a raw material for the precipitation of the pigment and the deposition and arrangement of the aluminum particles. When the content of the polyamide wax is less than 1% by weight in the base coat primary color, the sedimentation stability of the pigment and aluminum particles is poor. It is preferable that it is contained in the above-mentioned range because a sexual problem may appear. If the addition amount of the base coat is less than 1 wt.%, The stability of the aluminum particles and the pigment in the final coating is poor. If the amount of the pigment is more than 5 wt.%, Adhesion problems with the top coat may occur. By weight.
상기 폴리올레핀 왁스는 폴리아마이드 왁스와 유사 효과를 발휘하는 원료로서 베이스코트 원색에서 1중량% 미만이면 안료 및 알루미늄 입자의 침강안정성이 떨어지며, 5중량%를 초과하면 상도도료와의 부착성 문제가 나타날 수 있다. 또한 베이스코트 조정용 투명에서 제외하게 되면 최종도료의 알루미늄 입자와 안료의 침강안정성이 떨어지며, 5중량% 이상 첨가하게 되면 위와 마찬가지로 상도도료와의 부착성 문제가 나타날 수 있다. 따라서 전술한 범위로 함유되는 것이 바람직하다.The polyolefin wax is a raw material exhibiting a similar effect to the polyamide wax. When the content of the polyolefin wax is less than 1% by weight based on the base coat color, the sedimentation stability of the pigment and the aluminum particles is poor. When the content exceeds 5% by weight, have. In addition, if it is excluded from the transparency for adjusting the base coat, the settlement stability of the aluminum particles and the pigment in the final paint is poor. If the pigment is added in an amount of 5 wt% or more, adhesion problems with the top coat may occur. Therefore, it is preferable that it is contained in the above-mentioned range.
상기 아크릭틱소토픽레진은 알루미늄 입자의 균일한 배열을 잡아주는 원료로서 베이스코트 조정용 투명에 1중량% 미만으로 첨가하게 되면 그 효과가 미미하게 나타나고, 5중량%를 초과하면 도막외관이 저하되기 때문에 상기 범위로 함유되는 것이 바람직하다.When the acrylic resin is added in an amount of less than 1% by weight based on the base coat adjusting transparent material as a raw material for uniformly arranging the aluminum particles, the effect is insignificant. When the amount exceeds 5% by weight, By weight.
상기 에틸렌비닐아세테이트는 알루미늄 입자의 균일한 배열을 잡아주는 원료로서 베이스코트 조정용 투명에 15중량% 미만으로 첨가되면 알루미늄 입자의 얼룩이 발생하기 쉽고, 25중량% 이상이면 상도 도료와의 부착 불량 및 도막외관 등이 저하되기 때문에 상기 범위로 함유되는 것이 바람직하다.When ethylene vinyl acetate is added in an amount of less than 15% by weight to the transparent base coat adjusting material as a raw material for uniformly arranging the aluminum particles, the aluminum particles tend to be unevenly stained. When the content is 25% by weight or more, And the like. Therefore, it is preferable that the content is in the above range.
상기 베이스코트 조정용 투명의 첨가제는 도장되는 소지의 표면에 작용하는 첨가제(ex. 폴리실록산 표면용 첨가제)로서 도료에 첨가되지 않을 시 도장 후 분화구 모양의 불량 현상 등이 나타날 수 있으며, 0.5중량% 이상 적용되면 기포가 다량 발생되거나 도막외관 등이 저하되기 때문에 상기 범위로 함유되는 것이 바람직하다.The additive for the basecoat for adjusting the base coat is an additive (eg, an additive for the polysiloxane surface) which acts on the surface of the substrate to be coated. If not added to the coating, it may show a bad phenomenon like a crater after coating. The bubbles are generated in a large amount or the outer appearance of the coating film is deteriorated.
