Description
Technical Field
The present invention relates to an optical reflective film.
Background
The liquid crystal display does not emit light, the display function benefits from modulating the light emitted by the backlight source, and the performance index of the display depends on the performance of the backlight source, so the quality of the light source performance of the backlight module directly influences the display quality of the liquid crystal. The reflective film is one of the most important optical films in the backlight module of the liquid crystal display, and in the liquid crystal display, the reflective film is arranged at the bottom of the backlight module of the light guide plate and reflects the light leaked from the light source back to the light guide plate, so that the light can be intensively projected from the front side, and the light is prevented from leaking, thereby achieving the purpose of increasing the use efficiency of the light. However, the heat generated by the long-time operation of the backlight module can cause the reflective film to generate thermal shrinkage deformation, and meanwhile, the reflective film is generally fixed in the backlight module by adhering shading glue at the edges of two surfaces, and the space above the reflective film is insufficient, so that the reflective film easily generates bad phenomena such as film arching, folding, layering and the like, and the display effect is seriously influenced. The structure of the reliability of the optical film is not designed in the traditional backlight module structure. Therefore, the prior art is not sufficient and needs to be improved.

the lower resin layer is coated with a glue layer containing an antistatic agent, and a layer of stripping film is adhered on the glue layer;
the reflection film base layer comprises a main body resin, organic particles incompatible with the main body resin and inorganic particles incompatible with the main body resin, the core layer is separated from the main body resin and the inorganic particles from the main body resin after being stretched to form cavities, and the density difference between the organic particles and the main body resin is less than 0.25g/cm3。
Preferably, the resin layer is epoxy resin, acrylic resin or organic silicon.
Preferably, the shell layer of the temperature-adjusting particle with the core-shell structure is SiO2Or TiO2Or ZnO, or BaTiO3The core layer is paraffin, or polyethylene glycol, or butyl stearate.
Preferably, the antistatic agent is an antistatic agent SN, or an antistatic agent TM, or an antistatic agent SP, or an antistatic agent SH-105; the glue is acrylic glue, organic silicon glue or polyurethane glue.
Preferably, the difference in surface tension between the organic particles and the host resin is greater than 20 dyn/cm.
Preferably, the main resin is PET; the organic particles are PMMA particles with PTFE surface treated, and the particle diameter of the PMMA particles is less than 1 μm.

Preferably, the inorganic particles are titanium dioxide particles, the particle size of the titanium dioxide particles is 0.1-0.5 μm, and the weight percentage of the titanium dioxide particles in the reflecting film base layer is between 1% and 15%.
The invention has the beneficial effects that: the two sides of the reflecting film are coated with resin layers containing temperature-adjusting micro-particles, and the stable and proper working temperature of the film layer is kept by absorbing/releasing heat, so that the contraction and deformation of the reflecting film caused by the change of the environmental temperature are prevented. The reflection film after the stripping film is removed can be directly adhered in the backlight module, so that the phenomenon that the optical film is easy to generate film arch, wrinkle, layering and other bad phenomena due to large thermal shrinkage in the traditional shading glue fixing method is avoided, and the method is suitable for optical modules with different sizes.
