Embodiment 1

[0037] a protective film such as figure 1 As shown, it includes an anti-fingerprint and anti-glare coating 1 and a substrate layer 2 stacked sequentially from top to bottom.

[0038] The material of the base material layer 2 is PC.

[0039]The specific raw material composition of the anti-fingerprint and anti-glare coating 1 is calculated by weight percentage, including the following components: 10% of 9-official aromatic urethane acrylate, 5% of 15-official aliphatic urethane acrylate, acrylic acid (N-methyl all 5% fluorohexylsulfonamido)ethyl ester, 4% dipentaerythritol hexaacrylate, a 6-official monomer, 3% low-official monomer (2-official, three-official mass ratio is 2:1), fluorinated acrylic acid monomer 1.5% , nanodiamond 0.5%, acrylic-cage polysilsesquioxane monomer 0.8%, leveling agent 0.3%, light stabilizer 0.2%, hydrophobic and oleophobic additive 1.5%, photoinitiator 0.9% (cyclo Hexyl phenyl ketone (IRGACURE 184) and 2-hydroxy-2-methyl-1-phenyl-1-propanone (DAROC...

Embodiment 2

[0055] What is different from Example 1 is 8% of 9 official aromatic urethane acrylates in the composition of the raw material formula, 4% of 15 official aliphatic urethane acrylates, 8% of ethyl acrylate (N-methyl perfluorohexylsulfonamido), The nano-diamond is 0.8%, the acrylic-cage polysilsesquioxane monomer is 1.25%, the composite solvent is 66.55%, and the others are the same as in Example 1.

Embodiment 3

[0057] What is different from Example 1 is that 9-official aromatic polyurethane acrylic acid 12%, 15-official aliphatic polyurethane acrylate 3% in raw material formula composition, acrylate (N-methyl perfluorohexylsulfonamido) ethyl ester 8%, acrylic acid The base-cage polysilsesquioxane monomer is 1.5%, the fluorinated acrylic acid monomer is 2%, the composite solvent is 66.1%, and others are the same as in Example 1.

Abstract

The invention discloses an anti-fingerprint and anti-glare coating, a protective film containing the same and a preparation method thereof. The protective film includes an anti-fingerprint and anti-glare coating and a substrate layer sequentially stacked from top to bottom; the anti-fingerprint The fingerprint anti-glare coating is calculated by weight percentage, including the following components: 10-15% polyurethane acrylate, 5-8% fluorine-containing acrylate, 3-5% hexafunctional monomer, 2-3% low-functionality monomer , fluorine-containing functional monomer 1~2%, inorganic filler 0.5~0.8%, POSS monomer 0.5~2%, additive 2~3%, photoinitiator 0.5~1%, composite solvent 65~75%, each group The sum of the percentages by weight is 100%. The coating of the present invention has the characteristics of low haze, high light transmittance, high definition, good imaging quality and high visual visibility, and the coating can be used for a long time in relatively complex and severe environments.

Description

technical field [0001] The invention relates to the technical field of anti-glare coatings, in particular to an anti-fingerprint and anti-glare coating, a protective film containing it and a preparation method thereof. Background technique [0002] At present, substrates such as PC and PMMA are widely used in the fields of automotive central control panels and mobile phone screens due to their high transparency, light weight, impact resistance, and aging resistance. However, these materials have low surface hardness and are easy to scratch. It is easy to be stained with fingerprints and not resistant to dirt, so it is usually coated with a hard anti-fouling coating to solve this problem, but the effect is not satisfactory. [0003] The PC coating currently used in the market is not hard enough and not scratch-resistant, and its surface has a high gloss. When it is used in an environment with strong light, it is easy to cause glare, resulting in visual fatigue for users. It'...
