Abstract
Description
본 발명은 차량의 도막 표면에 피막을 적용하는 코팅제에 관한 것이다.TECHNICAL FIELD The present invention relates to a coating agent for applying a coating to a coating film surface of a vehicle.
종래의 글래스계 코팅제의 경우 도막 표면상에 적용된 피막에 크랙이 생기거나 벗겨지는 현상이 자주 발생하는 문제를 유발하고 있다.In the case of the conventional glass-based coating agent, cracks are often generated or peeled off on the coating film applied on the surface of the coating film.
최근들어, 대기중 오염으로 인해서, 미세 먼지가 증가하면서, 피막에 생긴 미세 크랙에 미세 먼지가 들어가서 피막을 손상시키고 차량을 보호하는 도막까지 손상시키는 문제가 증가하고 있다.In recent years, there has been an increasing problem of damaging the coating film, which damages the coating film and the vehicle, due to fine dust entering the fine cracks in the coating film due to the increase of the fine dust due to pollution in the atmosphere.
또한, 통상적으로 도막에 피막을 형성함에 있어서, 코팅전에 도막표면의 오물을 제거하여야 하는 별도의 공정이 요구되고 있다. 도막에 붙어 있는 오물은 유성, 수성 성분들로 구성되어 이를 고려한 세정작업을 별도로 수행하여야 하는 번거로움이 있다.Further, in forming a coating film on a coating film, a separate process is required to remove the dirt on the surface of the coating film before coating. The dirt attached to the coating film is composed of oil-based and water-based components, and it is troublesome to perform cleaning work separately considering this.
본 발명은 이러한 문제를 극복하기 위해 고안된 것으로서, 차량 도막의 변형에 관계없이 코팅된 피막에 크랙 또는 벗겨짐을 방지할 수 있을 뿐만 아니라, 피막의 강도를 개선하여 오랫동안 유지할 수 있으며, 코팅과 동시에 도막의 유수성 성분의 오물을 동시에 세정할 수 있는 코팅제를 제공하는 것을 목적으로 한다.The present invention has been devised to overcome such a problem, and it is an object of the present invention to provide a coating composition which can prevent cracking or peeling of a coating film regardless of deformation of a vehicle coating film, can improve the strength of the coating film for a long time, And it is an object of the present invention to provide a coating agent capable of simultaneously cleaning dirt of a water-borne component.
보다 바람직하게는, 본 발명의 코팅제는 코팅제의 장력을 보완하여 코팅된 피막에 발생되는 크랙을 발생을 방지할 수 있도록 하는 것을 목적으로 한다.More preferably, the coating agent of the present invention is intended to compensate for the tensile force of the coating agent to prevent the occurrence of cracks in the coated film.
본 발명의 목적은 3 내지 8 중량％의 플루오로알킬실란과, 5 내지 15 중량％의 3메틸3메톡시부탄올과, 80 내지 88 중량％의 디메틸실옥산을 포함하는 것을 특징으로 하는 도막에 피막을 형성하는 코팅제를 제공함에 의해 달성된다.It is an object of the present invention to provide a coating film coating comprising 3 to 8% by weight of a fluoroalkylsilane, 5 to 15% by weight of 3-methyl 3-methoxybutanol and 80 to 88% by weight of dimethylsiloxane ≪ / RTI >
본 발명의 코팅제를 제공함에 의해 자동차 도막에 피복되는 피막의 크랙 발생을 현저하게 감소시키며, 자동차 도막을 세정함과 동시에 코팅을 수행할 수 있다.By providing the coating agent of the present invention, it is possible to remarkably reduce the occurrence of cracks in the coating film coated on the automotive coating film, and to perform coating while cleaning the automotive coating film.
본 발명의 코팅제의 구현하는 실시예를 들자면 다음과 같으며, 이 실시예에 의해 본 발명의 범위를 제한하고자 하는 것은 아니다.The embodiment of the coating agent of the present invention is as follows, and the scope of the present invention is not limited by these examples.
본 발명의 코팅제는 코팅 및 발수 성분으로서, 3 내지 8 중량％의 플루오로알킬실란을 포함한다. 상기 플루오로알킬실란은 평활성과 발수성이 우수하여, 도막에 피막을 형성할 때 코팅을 용이하게 하며, 크랙발생을 방지할 수 있다.The coating of the present invention comprises 3 to 8% by weight of a fluoroalkylsilane as a coating and water repellent component. The fluoroalkylsilane is excellent in smoothness and water repellency, and is easy to coat when a coating film is formed on the coating film, and cracks can be prevented.
또한 본 발명의 코팅제는 상기 플루오로알킬실란의 평활성에 따른 장력 완화를 보완하기 위해 80 내지 88 중량％의 디메틸실옥산을 포함한다. 디메틸실옥산은 장력을 증진시킬 뿐만 아니라, 도막에 붙어있는 유성성분을 세정하는데 상당한 효과가 있다.In addition, the coating material of the present invention contains 80 to 88 wt% of dimethyl siloxane in order to compensate for the tension relaxation due to the smoothness of the fluoroalkyl silane. Dimethyl siloxane not only enhances the tensile strength but also has a considerable effect in cleaning oily components attached to the coating film.
디메틸실옥산의 성분 비율이 높으면, 장력이 증가하는 대신, 피막의 강도가 증가하면서, 크랙발생이 증가하게 된다. 반면에, 디메틸실옥산은 또한 세정 작용을 하여, 자동차 도막에 코팅제를 적용할 때, 별도의 세정 작업을 수행하지 않고서도 코팅을 동시에 적용할 수 있다. 디메틸실옥산의 성분 비율이 낮으면 본 발명의 코팅제의 세정능력이 떨어지게 된다. 본 발명의 발명자는 3 내지 8 중량％디메틸실옥산이 포함되는 것이 바람직한 것을 발견하였다.If the component ratio of dimethyl siloxane is high, the tensile strength is increased but the crack strength is increased while the film strength is increased. On the other hand, dimethylsiloxane also has a cleaning action, so that when applying a coating agent to an automotive coating, the coating can be applied at the same time without performing a separate cleaning operation. When the proportion of the component of dimethyl siloxane is low, the coating ability of the coating agent of the present invention is deteriorated. The inventors of the present invention have found that it is preferable to include 3 to 8 wt% dimethyl siloxane.
또한 본 발명의 코팅제는 5 내지 15 중량％의 3메틸3메톡시부탄올을 포함하여 도막에 붙어있는 유수성 오염물을 세정하게 한다.The coating of the present invention also contains 5 to 15% by weight of 3-methyl-3-methoxybutanol to clean the water-borne contaminants attached to the coating.
본 발명의 코팅제는 5 중량％의 플루오로알킬실란과, 10 중량％의 3메틸3메톡시부탄올과, 85 중량％의 디메틸실옥산을 포함하는 코팅제를 구성할 때, 크랙발생율이 유기규소로 구성된 다수군의 비교제품군에 비해서 크랙발생율을 10％이하로 크게 감소시키는 효과를 달성하였다.When the coating of the present invention comprises a coating comprising 5% by weight of fluoroalkylsilane, 10% by weight of 3-methyl 3-methoxybutanol and 85% by weight of dimethylsiloxane, the cracking rate is composed of organosilicon The cracking rate was significantly reduced to 10% or less as compared with the comparative product groups of a plurality of groups.
