Protective film for curved glass, preparation method thereof and film-coated curved glass

The invention provides a protective film for curved glass, a preparation method of the protective film and film-coated curved glass. The protective film for the curved glass includes: a supporting layer; the hardened layer that is arranged on one surface of the supporting layer; the flexible layer that is arranged on the surface, away from the hardened layer, of the supporting layer; the pressure-sensitive adhesive layer that is arranged on the surface, away from the supporting layer, of the flexible layer. According to the protective film provided by the invention, the flexible layer is directly synthesized on the reverse side of the supporting layer in situ, and the flexible layer and the supporting layer are prevented from being bonded through the adhesive layer, so that the protectivefilm has fitness and anti-warping performance, the manufacturing yield is higher, and the cost is lower. 本申请提出了用于曲面玻璃的保护膜及其制备方法、覆膜曲面玻璃。该用于曲面玻璃的保护膜包括：支撑层；硬化层，设置在支撑层的一个表面；柔性层，设置在支撑层远离硬化层的表面；压敏胶层，设置在柔性层远离支撑层的表面。本申请所提出的保护膜，其柔性层是直
