Embodiment 1

[0028] A composite optical film, comprising: a base layer 1, a first film layer 2, a second film layer 3 and an anti-reflection coating 4.

[0029] Wherein, the base layer 1 is disposed between the first film layer 2 and the second film layer 3 . The anti-reflection coating 4 is disposed on the side of the first film layer 2 away from the base layer 1 .

[0030] The base layer 1 is formed by blending acrylic resin, polyether-ketone ether resin and cellulose ester at a mass ratio of 9:4:3. The first film layer 2 is formed by blending polycarbonate, antioxidant, ultraviolet absorber and flame retardant. The second film layer 3 is formed by blending polyethylene terephthalate, antistatic agent, conductive agent and colorant. The thickness of the base layer 1 is 5㎛. The thickness of the antireflection coating 4 is 138nm.

Embodiment 2

[0032] The difference between embodiment 2 and embodiment 1 is that: it also includes an anti-glare coating 5 ; the anti-reflection coating 4 is arranged between the first film layer 2 and the anti-glare coating 5 . And the base layer 1 is formed by blending acrylic resin, polyether-ketone ether resin and cellulose ester at a mass ratio of 4:5:7. The thickness of the base layer 1 is 150㎛. The thickness of the anti-reflection coating 4 is 150nm.

Embodiment 3

[0034] The difference between embodiment 3 and embodiment 1 is that: it also includes an anti-glare coating 5 ; the second film layer 3 is arranged between the base layer 1 and the anti-glare coating 5 . And the base layer 1 is formed by blending acrylic resin, polyether-ketone ether resin and cellulose ester at a mass ratio of 1:1:1. The thickness of the base layer 1 is 80㎛. The thickness of the anti-reflection coating 4 is 145nm.

Abstract

The invention discloses a composite optical film. The composite optical film comprises a base layer, a first film layer, a second film layer and an anti-reflection coating; the base layer is disposedbetween the first film layer and the second film layer; and the first film layer is disposed between the anti-reflection coating and the base layer. The composite optical film of the present inventionhas the advantages of structural simplicity, easiness in preparation, low moisture absorption, high transparency and good flexibility.

Description

technical field [0001] The invention relates to the technical field of optical elements, in particular to a composite optical film. Background technique [0002] With the advancement of electronic technology, composite optical films have been rapidly developed and diversified as optical components used in mainstream mobile electronic devices. As a key upstream raw material, optical film has the characteristics of high surface finish, high light transmittance, low haze, and small thickness tolerance, which can fully meet the market's requirements for large-scale, thin, lightweight, high-precision, and consistent optical films. , Reliability and adaptability to assembly and other aspects, and can be widely used in many fields, such as: flat panel display, touch panel, window, reflective sign, household appliances, computer and telephone casing, auto parts, keyboard, cosmetic bottle, etc. . However, the composite optical films on the existing market are often difficult to bal...
