The invention discloses light automobile laminated glass and a preparation method thereof, and belongs to the technical field of laminated automobile glass production. According to the light automobile laminated glass, thick glass, a film layer and flat thin glass are sequentially hot-bent from bottom to top, during vacuum pressing, the thin glass needs to be bent by the same curvature as the thick glass, and grooves are formed in the periphery of the flat thin glass. The thick glass and the thin glass are combined, so that the overall mass of the laminated glass is reduced, and the light weight is realized; grooves are formed in the periphery of the thin glass, the thin glass is composed of glass and gaps, and the gaps are isosceles triangles. The grooves are formed in the periphery of the thin glass in the automobile laminated glass, so that the bending deformation space is ensured during vacuum pressing, the automobile laminated glass is not easy to crack, the production yield is increased, and meanwhile, the optical distortion of a finished product is improved.
本发明公开了一种轻质汽车夹胶玻璃及其制备方法,属于夹胶汽车玻璃生产技术领域。该轻质汽车夹胶玻璃自下而上依次热弯厚玻璃、胶片层、平板薄玻璃,在真空压覆时,薄玻璃需弯曲同厚玻璃相同曲率,平板薄玻璃四周设置沟槽。厚玻璃与薄玻璃组合从而减轻夹胶玻璃整体的质量,实现轻质化;薄玻璃四周存在沟槽,由玻璃和间隙组成,间隙形状为等腰三角形;本发明汽车夹胶玻璃中薄玻璃四周设置沟槽,在真空压覆时保证了弯曲变形的空间,不易破裂,提高了生产良率,同时改善了成品的光畸变。
