Description
본 발명은 승용차 및 상용차에 적합한 불포화 폴리에스테르 퍼티에 관한 것으로, 더욱 상세하게는 우수한 연마성과 함께 핀홀 발생이 매우 적어 승용차 및 상용차의 보수 도장 시 퍼티 작업 시간을 현저하게 단축시킬 수 있고 비중이 낮아 승용차 및 상용차의 경량화에 도움이 될 수 있는 불포화 폴리에스테르 퍼티 조성물에 관한 것이다. 본 발명의 퍼티 조성물은 종래의 불포화 폴리에스테르계 퍼티와 동등한 물성을 보유하면서도 연마성이 우수하고 핀홀 발생이 거의 없다.
The present invention relates to an unsaturated polyester putty suitable for passenger cars and commercial vehicles, and more particularly, very low pinholes with excellent abrasiveness, which can significantly reduce the putty work time during repair painting of passenger cars and commercial vehicles, and has a low specific gravity. And it relates to an unsaturated polyester putty composition that can help to lighten the commercial vehicle. The putty composition of the present invention possesses the same physical properties as those of the conventional unsaturated polyester putty, and has excellent polishing properties and little pinhole generation.
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 mobile equipment that operates for a long time in various environments, the coating quality is very important in terms of durability, stability, maintenance and aesthetics of the vehicle.
승용차 및 상용차의 보수 도장 공정 중에서 차체 외판에 적용되는 도장 작업은 하도 도장, 퍼티 도장, 연마, 중도 도장, 연마, 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. The painting work applied to the outer shell of the car and commercial vehicles is carried out in the following order: undercoat, putty coating, polishing, intermediate coating, polishing, top coat (color paint, transparent). The drying time of putty and intermediate paint is generally about 30 minutes based on 20 ℃, and the urethane topcoat is generally about 30 minutes based on 60 ℃.
이중 퍼티 시공은 총 2~3회에 걸쳐 실시해야만 차체 외판의 골곡 부위를 보완할 수 있는데, 3회에 걸친 퍼티 작업에는 3번의 연마 작업이 필요하며, 연마 작업 후 핀홀 발생 시 핀홀 메꿈 작업을 실시하여야 상도 도장 후 미려한 외관을 얻을 수 있기 때문에 전체 보수 도장 공정에서 매우 중요한 공정이라고 할 수 있다.Double putty construction should be performed two or three times to supplement the curved part of the outer shell of the body.Three putty operations require three polishing operations, and pinhole filling is performed when pinholes are generated after the polishing operation. It can be said to be a very important process in the whole repair painting process because a beautiful appearance can be obtained after top coat coating.
현재 널리 사용되고 있는 승용차 및 상용차용 퍼티는 불포화 폴리에스테르계를 많이 사용하며, 도료 비중에 따라 경량형 퍼티와 중량형 퍼티로 나누어진다.The putty for passenger cars and commercial vehicles, which are widely used at present, uses unsaturated polyesters and is divided into lightweight putty and heavy putty according to the specific gravity of paint.
이중 중량형 퍼티는 연마성이 취약하여 연마 시간이 오려 걸리기 때문에 생산성 저하의 원인이 되고 있다.Since the double weight type putty is poor in polishing property and it takes a long time to polish, it is a cause of productivity decrease.
상기 경량형 퍼티는 핀홀 발생이 높기 때문에, 핀홀 메꿈 작업을 실시하여야 하므로 생산성 저하의 원인이 되고 있다.
Since the light putty has a high pinhole generation, the pinhole filling operation has to be performed, which causes a decrease in productivity.
본 발명은 종래기술의 문제점을 해결하기 위해 창안된 것으로서, 종래의 불포화 폴리에스테르 퍼티의 문제점인 연마성과 핀홀 발생을 개선하여 작업시간이 단축될 수 있는 승용차 및 상용차용 퍼티 조성물을 제공하는 것을 과제로 한다.

본 발명은 주제와 경화제로 이루어진 2액형 조성물을 대상으로 하나, 그 기술적 특징은 주제부에 있다. 경화제부는 종래의 경화제를 사용하는 것으로 족한바, 예컨대 일반적인 사이크로헥사논퍼옥사이드(CHPO) 35% 경화제를 사용할 수 있다.
The present invention is directed to a two-component composition consisting of a subject and a hardener, the technical features of which are in the subject. The curing agent part is sufficient to use a conventional curing agent, for example, can be used a common cyclohexanone peroxide (CHPO) 35% curing agent.
다음으로 각 성분을 상기와 같이 제한한 이유에 대해 구체적으로 설명한다.
Next, the reason why each component was restrict | limited as mentioned above is demonstrated concretely.
상기 불포화 폴리에스테르 수지는 주제 성분의 주성분 수지로서 Non-wax 타입을 사용하는 것이 바람직하며 그 예로 불포화지방산 관능기를 포함한 불포화 폴리에스테르 수지 등을 들 수 있다. 한편 불포화 폴리에스테르 수지가 35중량% 미만으로 첨가되면 내충격성, 굴곡성 및 안료 웨팅성 등이 저하되며, 55중량% 초과하여 첨가하면 유동성이 심해서 흐름저항성이 저하되기 때문에 상기 범위로 함유되는 것이 바람직하다.
The unsaturated polyester resin is preferably a non-wax type as the main component resin of the main component, and examples thereof include unsaturated polyester resins containing unsaturated fatty acid functional groups. On the other hand, when the unsaturated polyester resin is added in less than 35% by weight, impact resistance, flexibility, pigment wettability, etc. are lowered, and when it is added in excess of 55% by weight, it is preferable to be contained in the above range because the fluidity is severe and the flow resistance is lowered. .
상기 탈크는 2가지 종류를 병행하여 사용한다. 탈크의 총 합이 35중량% 미만이면 연마성이 저하되고, 65중량%를 초과하면 내충격성, 내굴곡성 및 도막외관이 저하된다. 최상의 연마성을 유지하기 위하여 13~15㎛ 탈크(예컨대 #325)와 10~12㎛ 메시 탈크(예컨대 #400)를 1 : 2~4의 중량비로 혼합하여 사용하는 것이 바람직하다.
The talc is used in combination of two kinds. If the total amount of talc is less than 35% by weight, the polishing property is lowered. If the total talc is more than 65% by weight, the impact resistance, the flex resistance and the appearance of the coating film are lowered. In order to maintain the best polishing property, it is preferable to mix 13-15 μm talc (eg # 325) and 10-12 μm mesh talc (eg # 400) in a weight ratio of 1: 2-4.
상기 경량 필러는 특수 안료의 하나로서 고분자 타입의 중공구상, 글라스 버블 등이 있으며 주로 고분자 타입의 중공구상을 사용하는데, 이는 일반 체질 안료에 비해서 흡유량이 높아 퍼티의 점도 조절을 용이하게 하며 연마성 향상과 퍼티의 비중을 낮추는 작용을 한다. 경량 필러를 0.5중량% 미만으로 첨가하면 상기 효과를 얻기 어렵고 2중량%를 초과하여 첨가할 경우 도막 외관 및 주걱 작업성이 저하되기 때문에, 상기 범위로 첨가하는 것이 바람직하다.
The lightweight filler includes polymer-type hollow spheres, glass bubbles, etc., and mainly uses polymer-type hollow spheres, which have a high oil absorption amount compared to general sieving pigments, which facilitates control of the viscosity of the putty and improves abrasiveness. Lowers the weight of putty and acts. When the light weight filler is added in less than 0.5% by weight, the above effect is hardly obtained, and when it is added in excess of 2% by weight, the appearance of the coating film and the spatula workability are deteriorated.
상기 티타늄 디옥사이드는 백색 안료의 하나로서, 루틸 타입과 아나타제 타입이 있으며 주로 저가의 아나타제 타입을 사용한다. 티타늄 디옥사이드를 1.0중량% 미만으로 첨가하면 탁한 색상이 나오며, 3.0중량%를 초과하여 첨가할 경우 연마성이 저하되기 때문에 상기 범위로 첨가하는 것이 바람직하다.
The titanium dioxide is one of the white pigments, and there are rutile type and anatase type and mainly use inexpensive anatase type. When the titanium dioxide is added in less than 1.0% by weight, a turbid color appears, and when it is added in excess of 3.0% by weight, it is preferable to add the titanium dioxide in the above range.
상기 스틸렌 모노머는 용제의 하나로서, 스틸렌 모노머를 5.0중량% 미만으로 첨가하면 도막 외관 및 주걱 작성성이 저하되고 10.0중량%를 초과하여 첨가할 경우 수직면 작업 시 흐름 현상이 발생하기 때문에, 상기 범위로 첨가하는 것이 바람직하다.
The styrene monomer is one of the solvents, and when the styrene monomer is added in less than 5.0% by weight, the appearance of the coating film and spatula is deteriorated, and when the styrene monomer is added in excess of 10.0% by weight, the phenomenon occurs in the vertical plane operation. It is preferable to add.
상기 분산제는 조성물 중의 고형분들을 고르게 분산시키는 기능을 하는 것으로서, 구체적으로 불포화 지방산 폴리아민 아마이드 염이나 산성 폴리에스테르 용액 등이 사용된다. 분산제는 0.1중량% 미만으로 첨가되면 분산 효과가 저하되고 2중량% 초과하여 첨가되면 퍼티의 물성이 저하되기 때문에 상기 범위로 첨가하는 것이 바람직하다.
The dispersant serves to evenly disperse the solids in the composition, and specifically, an unsaturated fatty acid polyamine amide salt or an acidic polyester solution is used. If the dispersing agent is added in less than 0.1% by weight, the dispersing effect is lowered, and if the dispersing agent is added in excess of 2% by weight, it is preferable to add the dispersing agent in the above range.
상기 소포제는 도막 형성 시 발생되는 기포를 소포시켜 핀홀 발생을 억제하는 기능을 하는 것으로서 구체적으로 비실리콘계 소포제를 사용한다. 소포제가 0.1중량% 미만으로 첨가되면 소포 효과가 저하되고 2중량% 초과하여 첨가되면 퍼티의 물성이 저하되기 때문에 상기 범위로 첨가하는 것이 바람직하다.
The antifoaming agent is a non-silicone antifoaming agent is specifically used as a function to suppress the generation of pinholes by defoaming the bubbles generated during the coating film formation. If the antifoaming agent is added in less than 0.1% by weight, the antifoaming effect is lowered, and when the antifoaming agent is added in excess of 2% by weight, it is preferable to add the antifoaming agent in the above range.
상기 유동성 조절제는 구체적으로 벤토나이트 등이 사용되며, 0.01중량% 미만으로 첨가되면 효과가 없고, 1중량% 초과하면 점성이 높아져 작업성이 저하되기 때문에 상기 범위로 첨가되는 것이 바람직하다.
Bentonite or the like is specifically used for the fluidity regulator, and when added in an amount of less than 0.01% by weight, it is not effective, and when it exceeds 1% by weight, it is preferable to add it in the above range because viscosity increases and workability is lowered.
상기 중합방지제는 구체적으로 하이드로퀴논 등이 사용되며, 0.01중량% 미만으로 첨가되면 도료 저장안정성이 저하되고 0.2중량% 초과하여 첨가하면 건조가 늦어지기 때문에, 상기 범위로 첨가되는 것이 바람직하다.
Hydroquinone is specifically used as the polymerization inhibitor, and if it is added in less than 0.01% by weight, the storage stability of the paint is lowered, and when it is added in excess of 0.2% by weight, it is preferable to add it in the above range.
상기 경화촉진제는 구체적으로 코발트 옥토에이트산 등이 사용되며, 1중량% 미만으로 첨가되면 건조시간이 늘어나고, 5중량% 초과하여 첨가하면 핀홀 발생률이 증가하기 때문에, 상기 범위로 첨가되는 것이 바람직하다.
Specifically, the curing accelerator is used, such as cobalt octoate acid, and when added in less than 1% by weight increases the drying time, when added in excess of 5% by weight increases the pinhole generation, it is preferably added in the above range.
본 발명에 따른 퍼티 조성물은 종래의 불포화 폴리에스테르계 퍼티에 비해 연마성이 우수하고 핀홀 발생률이 매우 적다.The putty composition according to the present invention has excellent polishing properties and very low pinhole incidence compared to conventional unsaturated polyester putty.
또한 본 발명에 따른 퍼티 조성물은 종래의 불포화 폴리에스테르계 중량형 퍼티에 비하여 20중량%의 중량 감소 효과를 얻을 수 있다.
In addition, the putty composition according to the present invention can obtain a weight reduction effect of 20% by weight compared to the conventional unsaturated polyester weight type putty.
이하에서는 본 발명의 바람직한 실시예를 기초로 본 발명을 구체적으로 설명한다. 그러나 본 발명의 기술적 사항은 이에 한정되거나 제한되지 않고 당업자에 의해 변형되어 다양하게 실시될 수 있음은 물론이다.Hereinafter, the present invention will be described in detail based on the preferred embodiments of the present invention. However, the technical matters of the present invention are not limited thereto, but may be variously modified and modified by those skilled in the art.
본 발명의 실시예에 따른 퍼티 조성물은 하기 표 1과 같은 조성을 갖는다.
Putty composition according to an embodiment of the present invention has a composition as shown in Table 1.
이상과 같은 성분으로 퍼티용 교반기를 사용하여 배합하고, 최종적으로 스틸렌 모노머를 투입하여 점도를 85,000 ~ 105,000cps로 조정한 후 교반 과정 중에서 혼입된 기포를 제거하는 탈포 공정을 실시하여 제조하였다.The above components were blended using a putty stirrer, and finally a styrene monomer was added to adjust the viscosity to 85,000 to 105,000 cps, followed by a defoaming step of removing bubbles mixed in the stirring process.
이와 같이 제조된 주제와 일반적인 사이크로헥사논퍼옥사이드(CHPO) 35% 경화제를 혼합하여 도막을 형성한 후 물성을 평가한 결과를 하기 표 2에 나타내었다. 측정방법은 한국 산업 규격(KS)을 인용하였으며, 한국 산업 규격(KS)에 측정 방법이 나와 있지 않는 경우에는 보편화되어 있는 측정 방법을 사용하였다.
The results of evaluating the physical properties after mixing the main material prepared in this way and a general cyclohexanone peroxide (CHPO) 35% curing agent to form a coating film are shown in Table 2 below. The measurement method was quoted by the Korean Industrial Standards (KS), and when the Korean Industrial Standards (KS) did not indicate a measurement method, a generalized measurement method was used.
상기 표 2에 나타나 있는 바와 같이 본 발명의 실시예에 따른 퍼티의 경우, 비중이 1.35이므로 1mm의 두께로 도장할 때, 기존 불포화 폴리에스테르 중량형 퍼티(비중 1.7)에 비해 약 20%의 중량이 감소한다. 이에 따라, 수직 하중이 감소하고 차량 운행 시 연료가 절감될 수 있다.As shown in Table 2, in the case of the putty according to the embodiment of the present invention, since the specific gravity is 1.35, when the coating is made with a thickness of 1 mm, the weight of about 20% is higher than that of the conventional unsaturated polyester weight type putty (specific gravity 1.7). Decreases. Accordingly, the vertical load can be reduced and fuel can be saved when the vehicle is running.
또한, 도막 연마 시 소요되는 시간은 30분 정도로 기존의 불포화 폴리에스테르 퍼티의 연마 소요시간인 50분에 비해 현저하게 단축되므로, 본 발명에 따른 퍼티를 차량에 적용 시 보수 작업 생산성이 크게 개선될 수 있다.In addition, since the time required for polishing the coating film is significantly shortened compared to the polishing time of the conventional unsaturated polyester putty, about 50 minutes, the maintenance work productivity can be greatly improved when the putty according to the present invention is applied to a vehicle. have.
또한, 핀홀 발생이 매우 적어 핀홀 메꿈 작업 공정을 줄일 수 있기 때문에 보수 작업 생산성이 크게 개선될 수 있다.In addition, the production of maintenance work can be greatly improved because the generation of pinholes is very small, which reduces the number of pinhole filling processes.
또한, 외관 평가에 있어서도, 기존 불포화 폴리에스테르 퍼티와 비교할 때 차이가 없이 양호하였다.Moreover, also in external appearance evaluation, it was favorable without a difference compared with the existing unsaturated polyester putty.
