The invention provides a surface protective film for a mobile phone screen under a bigger temperature difference environment. The surface protective film for the mobile phone screen under the bigger temperature difference environment is characterized by successively comprising a hydrophilic antifogging coating (1), a polymer film layer (2), an anti-blue light layer (3), an adhesive layer (4) and a stripping liner (5) from the top down, wherein the thickness of the polymer film layer (2) is controlled to be that of a PET film or PBT film which is 100 to 350 (mu)m, more preferably, the thickness range is 120 to 200 (mu)m, the surface roughness of the side, not in contact with the polymer film layer (2), of the hydrophilic antifogging film (1) is calculated to be 3 to 7 (mu)m according to the ten-point average roughness (Rz). By adopting the surface protective film for the mobile phone screen under the bigger temperature difference environment, the problems of anti-blue light properties and screen surface fogging under the bigger temperature difference environment are solved, furthermore, the technical effects of stable bonding and no adhesive residues can be reached.
