Scratch-resistant anti-reflection film

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 ...

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-reflection layer of the existing anti-reflection film usually adopts high fluorine-containing materials, such as the durable anti-reflection film disclosed in the Chinese patent with the publication number CN101809465A, so that the interlayer adhesion of the anti-reflection layer (interfacial adhesion) ) is weak and has low scratch resistance
