The invention provides laminated glass for a vehicle and application thereof.The laminated glass for the vehicle comprises outer glass, inner glass and a middle film, the outer glass is provided with a first surface facing the exterior of the vehicle and a second surface facing the interior of the vehicle, and the inner glass is provided with a third surface facing the exterior of the vehicle and a fourth surface facing the interior of the vehicle; the second surface and the third surface are connected through the middle film, an infrared reflection film is arranged between the outer glass piece and the inner glass piece, and a low-radiation film is arranged on the fourth surface. The mirror surface coefficient alpha of the laminated glass for the vehicle is smaller than or equal to 15, the mirror surface coefficient alpha is calculated according to the formula alpha = RL/TL2, RL is the visible light reflectivity of the laminated glass for the vehicle measured from one side of the interior of the vehicle, and TL is the visible light transmittance of the laminated glass for the vehicle. When the laminated glass for the vehicle is used as skylight glass of a vehicle roof, the use requirement of canceling a sunshade curtain can be met, the mirror reflection effect of the inner surface of the vehicle can be effectively improved, the user experience is improved, and the privacy of passengers is protected.
本发明提供了一种车辆用夹层玻璃及其应用,该车辆用夹层玻璃包括外片玻璃、内片玻璃和中间膜,外片玻璃具有朝向车外的第一表面和朝向车内的第二表面,内片玻璃具有朝向车外的第三表面和朝向车内的第四表面,中间膜将第二表面和第三表面接合,外片玻璃和内片玻璃之间设有红外反射膜,第四表面上设有低辐射膜;车辆用夹层玻璃的镜面系数α≤15,所述镜面系数α根据公式α=RL/TL2计算,RL为从车内一侧测量所述车辆用夹层玻璃的可见光反射率,TL为所述车辆用夹层玻璃的可见光透过率。将所述车辆用夹层玻璃用作车辆车顶的天窗玻璃时,能够满足取消遮阳帘的使用需求,并且可以有效改善车内面的镜面反射效果,提高用户体验和保护乘客隐私。
