Embodiment 1

[0084] The invention provides an optical composite film, the composite film includes a brightness enhancing layer and a diffusion layer, the diffusion layer is coated on the back of the brightness enhancement layer, the diffusion layer includes a resin and a resin crystal, and the resin crystal passes through the resin It is bonded to the back of the brightness enhancing layer; the raw material of the diffusion layer is coating liquid.

[0085] The preparation method of above-mentioned optical composite film is as follows:

[0086] 1. Raw material preparation: See Table 1 for the parts by weight of the glue and coating liquid;

[0087] 2. Glue preparation: Mix solid resin slices, methyl ethyl ketone, and toluene into the disperser, seal the dispersing barrel and pour 60°C constant temperature circulating water into the jacket, stirring time 3h, stirring speed 2800r / min; then reduce the stirring Speed ​​up to 800r / min, at the same time reduce the temperature of the constant te...

Embodiment 2

[0093] The preparation process of glue, coating solution and composite film is as in Example 1, and the material composition of glue and coating solution is shown in Table 2.

[0094] Table 2

[0095]

[0096] Wherein, the preparation process of glue is as follows:

[0097] Add the solid resin slices to the organic solvent, heat with 70°C constant temperature circulating water, heat to 70°C, stir at high speed while heating, stir at a high speed of 3000r / min, stir for 4 hours; dissolve the solid resin slices in the organic solvent middle;

[0098] Cool down the obtained resin solution, use constant temperature circulating water at 25°C to cool down, stir at low speed while cooling down, stir at a low speed of 1500r / min, stir for 4 hours to cool down the resin solution to 25°C, and precipitate part of the dissolved resin from the solvent Crystals are formed to obtain the glue.

Embodiment 3

[0100] The preparation process of glue, coating solution and composite film is as in Example 1, and the material composition of glue and coating solution is shown in Table 3.

[0101] table 3

[0102]

[0103] Wherein, the preparation process of glue is as follows:

[0104] Add the solid resin slices to the organic solvent, heat with 60°C constant temperature circulating water, heat to 60°C, stir at high speed while heating, stir at a high speed of 2500r / min, stir for 3 hours; dissolve the solid resin slices in the organic solvent middle;

[0105] Cool down the obtained resin solution, use constant temperature circulating water at 25°C to cool down, stir at a low speed while cooling down, stir at a low speed of 1000r / min, stir for 3.5 hours to cool the resin solution to 25°C, and partially dissolve the resin from the solvent Precipitation forms crystals to obtain the glue.

Abstract

The invention relates to an optical film, in particular to a glue, a coating fluid, an optical composite film and preparation methods thereof, overcomes the shortcoming that a conventional optical composite film cannot simultaneously have high transparency or remarkable concealing property, and provides the glue, the coating fluid and the optical composite film. The glue comprises resin crystals, an organic solvent, and resin dissolved in the organic solvent, wherein the resin crystals are dispersed in the organic solvent. In the preparation process of the glue, part of resin slices are crystallized in the dissolving process to form the nano-scaled resin crystals, and the optical composite film is prepared by the coating fluid which is prepared by coating the back side of a prism film with the glue. The optical composite film provided by the invention has good brilliance and concealing property.

Description

technical field [0001] The invention relates to an optical film, in particular to a glue, a coating solution, an optical composite film and a preparation method thereof. Background technique [0002] In recent years, the flat panel display industry has developed rapidly and is widely used in TVs, computer monitors, notebook computers, mobile phones, digital cameras, car DSC / DV, GPS navigators and other products. film, used in the backlight module behind the liquid crystal display. However, limited by the light guide principle of LGP in side-type displays, in addition to increasing the brightness of LEDs, the only way to increase the overall brightness of the display is to increase the brightness of the display by adding a light-enhancing film. [0003] However, due to cost considerations, more and more side-in display manufacturers choose to use composite films to replace the traditional structure of brightness enhancement film and diffusion film, because the composite film...
