This steel sheet member is chemically treated to reinforce corrosion resistance and to improve adhesion to its surface in order to prevent corrosion in the pretreatment process. In this way, the steel sheet member which has been treated is coated with a ground color layer so that various colors appear to paint a ground color, and an adhesive layer is applied to the surface of the ground color layer to improve adhesion between films. Since such processing is already known, a detailed description thereof will be omitted.

상기 바탕색 층은 폴리에스테르, 아크릴, 폴리우레탄계를 포함하는 도료를 사용하며 바탕색 도료의 두께는 건조 도막의 두께를 기준으로 하여 5～25㎛를 유지하도록 형성한다. The ground color layer is formed of a polyester, acrylic, polyurethane-based paint and the thickness of the ground color paint is formed to maintain 5 ~ 25㎛ based on the thickness of the dry coating film.

접착제 층은 폴리에스테르, 아크릴, 폴리우레탄, 에폭시 수지를 주 수지로 하고 멜라민과 이소시안네이트를 포함하는 가교제로 구성되며, 필름과 도료간의 부착력을 증진하고 외관이 미려하도록 하기 위하여 사용한다. 이 접착제 층은 건조 도막을 기준으로 2～15㎛를 유지하도록 형성한다.The adhesive layer consists of a crosslinking agent comprising polyester, acrylic, polyurethane, and epoxy resin as the main resin and including melamine and isocyanate, and is used to enhance adhesion between the film and the paint and to have a beautiful appearance. This adhesive bond layer is formed so as to maintain 2-15 micrometers with respect to a dry coating film.

바탕색 층의 상면에는 헤어라인 필름 부재가 부착되는바, 상기 헤어라인 필름 부재는 바탕색 층에 접착되는 접착제 층과 그 표면에 헤어라인 처리된 필름 층으로 구성된다. A hairline film member is attached to the top surface of the background color layer, and the hairline film member is composed of an adhesive layer adhered to the background color layer and a film layer hairlined on the surface thereof.

상기 헤어라인 처리된 필름에 이용되는 소지 필름으로는 폴리에스테르, 폴리프로필렌, 폴리에틸렌, 폴리비닐 필름 등을 사용할 수 있다.Polyester, polypropylene, polyethylene, polyvinyl film, and the like may be used as the base film used for the hairline treated film.

상기 필름은 표면에 자외선 차단 코팅층이나 나노 코팅층을 처리하여 용도에 적합하도록 기능성을 부여할 수 있다. 상기 코팅층은 폴리우레탄, 폴리에스테르 또는 아크릴계 수지로 이루어지며 1～2㎛의 두께로 도장하는바, 상기 접착제 층의 두께가 낮을 경우에는 바탕색 부재와 필름 간의 접착력이 저하되며, 접착제의 두께가 상기 범위보다 두꺼울 경우에는 바탕색이 제대로 표현되지 않아서 외관 결함을 나타낼 수 있다. The film may be treated with a UV coating layer or a nano coating layer on the surface to impart functionality to suit the application. The coating layer is made of polyurethane, polyester or acrylic resin and is coated with a thickness of 1 ~ 2㎛ bar, when the thickness of the adhesive layer is low, the adhesion between the ground color member and the film is lowered, the thickness of the adhesive is in the above range In the thicker case, the background color may not be represented properly, which may indicate appearance defects.

헤어라인 필름은 사포를 사용하여 헤어라인 질감이 나타나도록 하며 헤어라인의 두께와 간격은 사용되는 사포와 헤어라인 처리장치에 의하여 결정된다.The hairline film uses sandpaper to show the hairline texture and the thickness and spacing of the hairline is determined by the sandpaper and hairline treatment apparatus used.
