Description
Technical field
The present invention relates to optical film manufacturing technology fields, highlight optical film producing method more particularly, to a kind of high fog.
Background technique
Important component of FPD (FPD, such as the LCD, PDP etc.) industry as information industry be even more in recent years
It is rapidly developed.Flat-panel monitor be widely used in TV, computer monitor, laptop, mobile phone, digital camera,
On the products such as MP3, MP4, MP5, vehicle-mounted DSC/DV, GPS navigator.But these flat-panel monitors itself do not shine, produced
Picture light source be to be provided by backlight module therein, light source requirements uniformly, high brightness.Whether now using more
LED backlight or traditional CCFL backlight, the light issued is point light source or linear light source, rather than face light
Source.But passes through backlight module diffusion barrier, a uniform area source can be scattered in.When light passes through diffusion layer, lead to
The optical phenomenas such as refraction, the reflection constantly occurred in the different medium of two kinds of refractive index are crossed, to obtain the knot of optics diffusion
Fruit.The defects of existing optical diffusion there are optics luminance low, material is partially thick, diffusingsurface easily scratches, is unable to satisfy photoelectricity row
Industry high demand.
For example, the Chinese patent of application publication number CN1570675A discloses a kind of manufacturing method of photoelectric diffusion barrier,
Processing step are as follows: a. is by transparent or semitransparent substrate frame on coating machine platform；B. diffusion barrier ingredient is packed into the coating machine platform
In；C. the diffusion barrier ingredient is coated on the substrate front to form the diffusion barrier light-emitting surface；D. the diffusion barrier is placed in perseverance
Constant temperature and humidity frame is dried；E. the incidence surface for step a to d being repeated to form the diffusion barrier to the substrate reverse side.Using the hair
Photoelectric diffusion barrier made from bright method is there are optics luminance is low, and mist degree and light transmittance are bad, and the quality of photoelectric diffusion barrier entirety is not
The defects of high, while in process of production, diffusion barrier paint stability is poor, and the light diffusion particle spread in coating easily settles

Bright the problems of the optical film for the prior art improves and optimizates light diffusion formulation for coating material, essentially consists in: increasing
Pentaerythritol acrylate, butyl acrylate, poly- diethanol, dibutyltin dilaurate and nano silica, season are added
Penta tetrol acrylate is colourless or light yellow liquid, can be compatible with other components perfection, has high crosslink density, rapid curing
Characteristic, filming performance can be improved, while can make to spread optical film there is excellent flexibility and scratch-resistant, but season penta
The addition of tetrol acrylate can improve the mobility of whole system, influence paintability, therefore joined two fourths in the present invention
Base tin dilaurate, dibutyltin dilaurate can inhibit the mobility of whole system of the present invention, can solve that season penta is added
Problem brought by tetrol acrylate, while dibutyltin dilaurate can also improve the photostability of upper diffusion optical film
And the transparency, but the addition of dibutyltin dilaurate can make a large amount of bubble of light diffusion coating generation, the present invention passes through
Nano silica is added to solve the problems, such as this, the light transmittance and index of refraction of silica are good, will not influence diffusion optical film
Performance, and nano silica have foam-inhibiting effect, can reduce light diffusion coating in bubble, be conducive to improve diffusion optics
The quality of film, in addition nano silica can improve the hardness of Diffusion barrier layer, improve scratch resistance performance；Butyl acrylate, which has, to be increased
Light action can improve Diffusion barrier layer lustrous surface, improve the light transmittance of light, reduce light loss；Poly- diethanol can improve light expansion
The stability and homogeneity for dissipating coating, effectively avoid coating from settling, and are conducive to improve coating performance.
(2) back side that ultraviolet curing acrylic resin is spread evenly across semi-finished product is formed into film layer of adding lustre to, after solidification i.e.
Obtain finished product.It is obtained add lustre to film layer can composite protection film to play a protective role.
Preferably, it is 5 ~ 10 μm that light, which spreads coating coating thickness, in step (1).
Preferably, the smooth diffusion particle is polymethacrylates particle, granules of polystyrene, gathers in step (1)
One of siloxane particles, polyacrylic acid granules are a variety of.
Preferably, the partial size of the smooth diffusion particle is 0.1 ~ 1 μm.
Preferably, the substrate is PET film in step (1).
Preferably, in step (1), the drying specific steps are as follows: be warming up to 100 ~ 120 DEG C, dry 40 ~ 60s.
