Description
본 발명은 특히 자동차 내장재에 사용되기에 적합한 수성 도료 조성물에 관한 것으로서, 더욱 상세하게는 클로리네이티드 폴리올레핀 수지, 아크릴 변성 폴리올레핀 수지, 알킬 (메트)아크릴레이트 수지와 같은 조막수지, 수분산형 우레탄 수지 및 가교제를 포함하며, PPF/TPO 복합소재에 우수한 외관 및 부착 성능을 나타냄과 동시에 종래 용제형 도료의 문제점이었던 냄새, 예컨대 차량 실내의 냄새를 최소화하고, 내화학성을 향상시킨 세미아크릴 우레탄형 수성 도료 조성물에 관한 것이다.The present invention relates in particular to aqueous coating compositions suitable for use in automotive interiors, and more particularly to chlorinated polyolefin resins, acrylic modified polyolefin resins, film-forming resins such as alkyl (meth) acrylate resins, water-dispersible urethane resins, and Semi-acrylic urethane-based water-based coating composition containing a cross-linking agent, exhibiting excellent appearance and adhesion performance to the PPF / TPO composite material and at the same time minimize the smell of the conventional solvent-type paint, such as the smell of the vehicle interior, and improved chemical resistance It is about.
자동차용 플라스틱 분야에서 용제형 도료는 휘발성 유기 화합물(volatile organic compound, VOC)의 영향으로 인체에 유해성 및 환경 오염의 문제를 일으키고, 건조 과정에서 완전하게 휘발되지 못한 잔류 용제 및 도막에 유연성을 부여하는 가소제의 영향으로 자동차 내부와 같은 밀폐 환경에서 냄새를 유발시킬 뿐만 아니라, 용제형 도료의 구성 성분 중, 예를 들면, 자이렌 또는 메틸이소부틸케톤과 같은 용제는 플라스틱 표면의 균열이나 침식을 유발시키는 문제점이 있다. Solvent-based paints in the field of automotive plastics are harmful to humans and pollutants due to the effects of volatile organic compounds (VOCs) and provide flexibility to residual solvents and coatings that are not completely volatilized during drying. The influence of plasticizers not only causes odors in enclosed environments, such as in automobiles, but also solvents such as xylene or methyl isobutyl ketone in solvent-based paints can cause cracking or erosion of plastic surfaces. There is a problem.
이에 반해 수성 도료는 기존의 용제형 도료에 비하여 휘발성 유기 화합물의 함량을 감소시킴으로써 친환경적이고 인체에 미치는 영향이 적으며, 차내에서 발생하는 냄새를 감소시킨다. 또한, 자이렌 또는 메틸이소부틸케톤 등의 용제에 의한 플라스틱 표면의 균열이나 침식을 억제시키는 장점이 있다. On the other hand, water-based paints are environmentally friendly and have less impact on the human body by reducing the content of volatile organic compounds than conventional solvent-based paints, and reduce the odor generated in the car. In addition, there is an advantage of suppressing cracking or erosion of the plastic surface by a solvent such as xylene or methyl isobutyl ketone.
플라스틱 소지와의 부착을 위해 용제형 도료에서는 메틸메타크릴레이트나 부틸메타크릴레이트 등을 사용하는데, 이들은 도막의 내마모성이나 내스크래치, 내약품 또는 내알코올성 등의 물성 저하 요인으로 작용할 수 있다.In order to adhere to plastics, solvent-based paints use methyl methacrylate or butyl methacrylate, which may act as deterioration factors such as abrasion resistance, scratch resistance, chemical resistance or alcohol resistance of the coating film.
한편, 플라스틱 표면의 습윤 성능은 주로 화염처리나 코로나 방전처리에 따른 소지와 도료간의 표면장력에 의해 결정되는데, 이것은 플라스틱 수지의 표면 에너지를 증가시켜 도료의 표면 에너지와 동등한 수준으로 맞추는 방법이며, 도료적 관점에서는 페인트의 표면 에너지를 낮게 하여 플라스틱의 수준으로 조정해야 한다.On the other hand, the wettability of plastic surfaces is mainly determined by the surface tension between the base and the paint by flame treatment or corona discharge treatment. This is a method of increasing the surface energy of plastic resin to the level equivalent to the surface energy of paint. From the point of view, the surface energy of the paint should be lowered to the level of the plastic.
자동차 내장 부품용으로 주로 쓰이는 폴리프로필렌 소지에 적용되는 도료에 있어서, 수지는 일반적으로 페인트의 부착 특성을 부여하는 기능을 하기 때문에 도료-소지간의 계면에서 우선적으로 흡수되지 않아야 한다. 따라서, 도료에 포함되는 다른 구성물의 종류나 투입량이 함께 고려되어야 하며, 혼합되는 수지와 기타 구성물 즉, 안료, 충진제, 첨가제 등과의 상호작용도 고려되어야 한다. 수지는 안료를 완전히 습윤시켜야 수지와 플라스틱 소지의 접촉 부위에서 양호한 부착을 얻을 수 있다.In paints applied to polypropylene substrates, which are mainly used for automotive interior parts, resins should generally not be absorbed preferentially at the interface between the paint and the substrate because they generally serve to impart the adhesion properties of the paint. Therefore, the kind or dosage of other components included in the paint should be considered together, and the interaction of the resin and other components to be mixed, ie, pigments, fillers, additives, etc., should also be considered. The resin must be fully wetted with the pigment to obtain good adhesion at the contact area of the resin with the plastic substrate.
수성 도료에 수분산형 폴리우레탄과 아크릴계 에멀젼의 물리적 혼용 또는 공중합 형태를 도료에 적용하면, 수분산형 폴리우레탄의 빠른 경도 전개, 우수한 내마모성 및 내약품성 등의 이점과 아크릴계 에멀젼 구성 성분의 우수한 안료 습윤성 및 경제적인 원재료비 등의 이점을 함께 얻을 수 있다. Applying a physically mixed or copolymerized form of a water-dispersible polyurethane and an acrylic emulsion to the paint on the water-based coating provides advantages such as rapid hardness development, excellent wear resistance and chemical resistance of the water-dispersed polyurethane, and excellent pigment wettability and economical properties of the acrylic emulsion component. Benefits such as raw material costs can be obtained.
그러나 이러한 에멀젼 수지는 내수성이 부족하다는 단점을 갖고 있으므로, 이를 보완하고자 소수성 모노머를 사용하는 방법 등이 시도된 바 있으나, 이 경우 극성의 피착재와의 부착력을 저하시키는 문제점이 있다.However, since the emulsion resin has a disadvantage in that the water resistance is insufficient, a method using a hydrophobic monomer has been attempted to compensate for this, but in this case, there is a problem of lowering the adhesive strength of the polar adherend.
상기한 바와 같은 종래기술의 문제점들을 해결하고자 본 발명은, 유기용제를 함유하지 않는 수성 도료로서 기존 수성 도료의 문제점을 극복하고 충진제를 사용하는 폴리프로필렌(Polypropylene filler, PPF) 및 열가소성 폴리올레핀(Thermoplastic polyolefin, TPO)과 같이 서로 다른 소재에 대하여 부착성 및 내화학성 등의 자동차 신뢰성 규격을 만족시키는 도료 조성물을 제공하는 것을 기술적 과제로 한다.In order to solve the problems of the prior art as described above, the present invention, a polypropylene (Polypropylene filler, PPF) and thermoplastic polyolefin using a filler to overcome the problems of the existing aqueous coating as an aqueous paint containing no organic solvent It is a technical problem to provide a coating composition that satisfies automotive reliability standards such as adhesion and chemical resistance to different materials such as TPO).
