Example Embodiment
[0038] The preparation method of the scratch-resistant optical reflective film provided by the present invention includes the following steps:
[0039] (1) Preparation of coating solution: add adhesive, particles, ultraviolet absorber, and solvent in sequence, and stir for 1-3 hours;
[0040] (2) Coat the coating liquid obtained in step (1) uniformly on the substrate, and bake it at 80-120°C for 1-30 minutes.
[0041] The scratch-resistant optical reflective film is prepared according to the above method, and the test methods for the properties of the obtained reflective film are briefly described as follows:
[0042] Scratch degree: Put the reflective film into the backlight module, and then put it into the vibration test box for a 2-hour vibration test. After the vibration test is completed, take out the light guide plate and the reflective film, and observe the light guide plate and the reflective film. Scratches on the contact side of the light guide plate.
