Description

발수력이 개선된 발수 코팅제{Coating Agent For Enhanced Water Repellency}[0001] Coating Agent For Enhanced Water Repellency [

본 발명은 코팅 대상물, 바람직하게는 차량의 발수력이 개선된 발수 코팅제에 관한 것이다.The present invention relates to a coating material, preferably a water repellent coating material having improved water repellency of a vehicle.

자동차 도장 표면을 보호하기 위해서, 여러가지 코팅 제제가 출시되어 있다. 이러한 코팅 제제의 경우, 손상된 도장 부위에 물이 스며들어, 결국에는 자동차 표면의 손상을 야기한다.In order to protect the car paint surface, various coating formulations are available. In the case of such a coating formulation, water seeps into the damaged coating area and eventually causes damage to the surface of the vehicle.

상기 코팅 제제에 의해 자동차 도장 표면에 코팅된 코팅 제제는 통상적으로 상기 도장 표면에 코팅 막을 형성하여 도장 표면을 보호하게 된다. 이와 같이 형성된 코팅 막의 표면위에 물이 묻을때, 이 물은 상기 코팅 제제에 의해 형성된 막을 따라 퍼져나가서, 상기 코팅 막위에 물에 의해 형성된 층을 더 형성하게 된다.The coating formulation coated on the car paint surface by the coating formulation usually forms a coating film on the coating surface to protect the coating surface. When water is deposited on the surface of the thus formed coating film, the water spreads along the film formed by the coating formulation to further form a layer formed by water on the coating film.

상기 코팅 제제에 의해 형성된 코팅 막의 표면상에는 평상시에 많은 먼지, 불순물 등이 묻어있게 되며, 이러한 상태에서 코팅 막의 표면상에 물이 적셔질때, 물로 이루어진 층의 하부와 상기 코팅 막의 표면사이에 상기 먼지, 불순물등의 부유물이 쌓여지게 된다.A large amount of dust, impurities, and the like are normally present on the surface of the coating film formed by the coating formulation. When water is wetted on the surface of the coating film in this state, the dust, Floating matters such as impurities are piled up.

이와 같이, 물로 이루어진 층과 상기 코팅 막 사이에 이러한 퇴적물들이 쌓이게 되면, 이러한 퇴적물 중의 소정의 성분들이 자동차의 도장 면을 손상시키게 되고, 결국에는 자동차의 표면의 손상을 야기하게 된다.As such, when these deposits accumulate between the layer of water and the coating film, certain components of such deposits damage the surface of the car and eventually damage the surface of the car.

본 발명은 상술한 바와 같이, 상기 코팅 제제에 의해 형성된 코팅 막의 표면에 물이 적셔질 때, 물이 상기 코팅 막의 표면에서 넓게 퍼져나가서 물로 이루어진 막을 형성하지 못하도록 한다. 이에따라, 물로 이루어진 막의 하부와 상기 코팅 막의 표면사이에 상기 먼지, 불순물등의 부유물이 쌓여지는 것을 방지할 수 있는 코팅제를 제공하는 것이다.As described above, the present invention prevents the water from spreading widely on the surface of the coating film to form a film of water when the surface of the coating film formed by the coating formulation is wetted with water. Accordingly, it is an object of the present invention to provide a coating agent capable of preventing floating of dirt, impurities and the like between the lower part of the film made of water and the surface of the coating film.

이를 위해서는, 코팅제의 발수성을 높여서 적셔진 물이 코팅 막의 표면상에서 넓게 퍼져나가서 물로 이루어진 막을 형성하지 못하도록 하는 조성물을 제공하여야 한다..To this end, it is necessary to provide a composition which enhances the water repellency of the coating agent so that the wetted water spreads widely on the surface of the coating film so as not to form a film composed of water.

본 발명에서는 코팅제의 발수성을 개선시켜서, 광택을 제공하고자 하는 대상물에 적용된 코팅제의 발수성으로 인해서, 형성된 코팅 막의 표면위에 물이 적셔지더라도 물이 넓게 퍼지지 않도록 하는 조성물을 제공한다.The present invention provides a composition that improves the water repellency of a coating to prevent water from spreading even when water is wetted on the surface of the formed coating due to the water repellency of the coating applied to the object to provide gloss.

본 발명의 목적은 발수 및 광택을 구현시키기 위한 기저 또는 기초(베이스) 제제로 사용되는 10 내지 20중량％의 하기식의 실리콘 수지와;It is an object of the present invention to provide a silicone resin of 10 to 20% by weight of a silicone resin of the following formula, used as a base or base (base) formulation for realizing water repellency and gloss;
