Problems solved by technology

[0003] However, the existing anti-reflection film is difficult to balance anti-reflection performance and scratch resistance
Among them, although the anti-reflection film disclosed in the Chinese patent with the publication number CN109298470A has low reflectivity, it is difficult to have excellent scratch resistance.
In addition, the anti-re

Embodiment 1

[0020] Example 1: Such as figure 1 As shown, a scratch resistant anti-reflective film is applied to the substrate 1 by first, heating the hardening layer 2 having a thickness of 3 μm, then in the hardened layer 2 through 65 ° C. The anti-reflective layer coating liquid is applied, and the thickness of the anti-reflection layer 3 having a thickness of 100 nm is formed by heating for 1 min and UV curing, wherein UV curing energy is 600 mJ / cm. 2 The material components of the hardening layer 2 are measured by weight parts: 100 parts of double cured resin (Blue Coke Lucun L-8464), 5 servants (Irgacure 184), 5 parts of isocyanate (Sanjing Chemical D-131N), 10 enclosed isocyanate (XB-G282), 280 parts of solvent (meth isoisineamone) and 0.5 parts of other auxiliaries (BYK 300 leveling agent); the material components of the anti-reflective layer 3 are calculated by weight parts: 100 parts of light curing resin (R0310), 15 parts of hollow silica nanoparticles (A311), 4500 parts solvent (...

Embodiment 2

[0021] Embodiment 2: This embodiment is substantially the same as that of the Examples, and the difference is only in the present embodiment: the closed isocyanate is 40 parts by weight.

Embodiment 3

[0022] Example 3: This embodiment is substantially the same as that of the examples, only in the present embodiment: isocyanate is 10 parts by weight, and the closed isocyanate is 5 parts by weight.

Abstract

The invention discloses a scratch-resistant anti-reflection film which is obtained by the following steps of coating a base material with a hardened layer coating liquid, heating and curing at 60-80 DEG C until the surface is dry to form a hardened layer, then coating the hardened layer with an anti-reflection layer coating liquid, heating and curing at 80-150 DEG C for at least 1 min, and carrying out UV curing to form an anti-reflection layer. The UV curing energy is more than 600 mJ/cm<2>. The hardened layer is prepared from the following material components in parts by weight: 100 parts of dual-cured resin, 1-10 parts of a photoinitiator, 1-10 parts of isocyanate, 5-40 parts of blocked isocyanate, 100-850 parts of a solvent and 0.5-10 parts of other auxiliaries; the anti-reflection layer is prepared from the following material components in parts by weight: 100 parts of light-cured resin, 10-80 parts of hollow nano silicon dioxide particles, 4000-10000 parts of a solvent and 1-10 parts of other auxiliaries. The anti-reflection film has the advantages of excellent anti-reflection function, strong interlayer adhesive force of the anti-reflection layer and strong scratch resistance.

Description

Technical field [0001] The present invention relates to an anti-reflection film, and more particularly to a scratch resistant anti-reflection film. Background technique [0002] Currently, various display touch screens typically have an anti-reflective film that minimizes reflections from the outside. The anti-reflective film is a multilayer structure. Currently, there are two main methods of the anti-reflective film: dry method and wet method. The anti-reflective film prepared by the dry method is more powerful than the anti-reflection function prepared from the wet method, but the dry process is a batch laminated, forming the process of forming the layers, and the equipment High cost. Further, a multilayer structure such as a hardening layer (high refractive index layer) and an anti-reflective layer (low reflective coating) is provided on the substrate to achieve anti-reflection film has been commercialized. [0003] However, existing anti-reflective membranes are difficult to ...
