Problems solved by technology

[0007] There are few reports on the preparation and application of the adhesive of the AF screen protective film at home and abroad, because there are many problems in the AF screen protective film with the adhesive layer in the prior art, mainly including: 1. Protective film The peeling force attached to the AF screen is not enough, and the adhesion will not be firm; 2. The peeling force of the protective film is unstable and prone to attenuation; 3. The protective film attached to the AF screen is prone to residual glue when placed in a high-temperature and high-humidity environment , this will cause the AF screen to be easily polluted when placed in a high-temperature and high-humidity environment; 4. The protective film used to paste the AF curved screen is not firmly attached, mainly due to low peeling force and low initial adhesion.

Abstract

The invention relates to the field of adhesives, and specifically discloses an adhesive applied to an AF display screen protective film, a preparation method thereof, and a protective film, wherein the adhesive includes the following components by weight: acrylic resin 80~ 120 parts; 2~10 parts of isobornyl methacrylate; 0.5~5 parts of lauryl acrylate; 0.1~1 part of 1,6-hexanediol diacrylate; 5~15 parts of hydroxyethyl acrylate; 1.5-2.0 parts of photoinitiator; 0.30-0.50 parts of second photoinitiator. Compared with the prior art, the present invention adopts the method of photoinitiation to prepare acrylic resin, the reaction rate is fast, the production efficiency is high, it is suitable for industrialized production, the solid content of the acrylic resin obtained is 100%, and it has no pollution to the environment; The AF display protective film made of the provided adhesive has high and stable peeling force, no adhesive residue in high temperature and high humidity, excellent comprehensive performance, can be re-pasted repeatedly, and can be firmly attached to the curved screen of AF without warping, and can Play a very good protective role.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive applied to a protective film of an AF display screen, a preparation method thereof and a protective film. Background technique [0002] AF display refers to the anti-fingerprint screen. This type of screen has ultra-low surface energy and hydrophobic and oleophobic properties. General materials cannot effectively infiltrate / adhere on the surface, and are not easy to pollute. It can be easily wiped off without leaving traces. Due to its superior isolation effect, this type of screen is widely used in various display devices, especially electronic products that require touch operation. [0003] In order to avoid defects in the AF display during processing, assembly, inspection, transportation, etc., as well as scratches and cracks on the mobile phone screen during use, it is necessary to paste a protective film on the surface of the AF display. However, because the surface of ...
