The present invention relates to a sunroof panel for a vehicle which is formed by curing a thermoplastic molding composition. The thermoplastic molding composition comprises a polycarbonate resin; 10-900 parts by weight of a polyester copolymer formed by copolymerization of glycol-modified polyethylene terephthalate and isosorbide with respect to 100 parts by weight of the polycarbonate resin; and 5-500 parts by weight of polycyclohexane terephthalate with respect to 100 parts by weight of the polycarbonate resin. In regard to the glycol-modified polyethylene terephthalate, ethylene glycol is partially substituted with cyclohexane dimethanol. The isosorbide is copolymerized with the glycol-modified polyethylene terephthalate and is partially substituted for or added to the ethylene glycol and the cyclohexane dimethanol. The surface of the sunroof panel for a vehicle is coated with a silane-based coating liquid so as to improve surface hardness. According to the present invention, a sunroof panel for a vehicle with excellent flame retardancy, weather resistance, chemical resistance and wear resistance can be obtained by using a polycarbonate-based thermoplastic molding composition which shows birefringence being zero or close to zero and also has excellent flame retardancy.

    본 발명은, 폴리카보네이트 수지와, 상기 폴리카보네이트 수지 100중량부에 대하여 글리콜 변성 폴리에틸렌테레프탈레이트와 이소소비드가 공중합 반응되어 형성된 폴리에스터 공중합체 10∼900중량부와, 상기 폴리카보네이트 수지 100중량부에 대하여 폴리시클로헥산 테레프탈레이트 5∼500중량부를 포함하는 열가소성 성형 조성물이 경화되어 이루어지며, 상기 글리콜 변성 폴리에틸렌테레프탈레이트는 에틸렌글리콜의 일부가 시클로헥산디메탄올로 치환된 것이고, 상기 이소소비드는 상기 글리콜 변성 폴리에틸렌테레프탈레이트와 공중합 반응되어 상기 에틸렌글리콜과 상기 시클로헥산디메탄올을 일부 대체하거나 부가된 형태로 이루어지며, 표면경도를 개선하기 위하여 실란계 코팅액으로 표면이 코팅되어 있는 것을 특징으로 하는 차량용 선루프 패널에 관한 것이다. 본 발명에 의하면, 제로 또는 제로에 가까운 복굴절을 나타내면서 우수한 난연성을 갖는 폴리카보네이트 기반의 열가소성 성형 조성물을 이용하여 우수한 난연성, 내후성, 내화학성 및 내마모성을 갖는 차량용 선루프 패널을 얻을 수가 있다.
