Problems solved by technology

[0003] At present, the use of LCD screens has been popularized to most electrical products. LCD screens are favored by the public for their high image quality, high resolution, and high definition. Flowers, after a long time, dirt, oil, mold, etc. will adhere to the screen due to static electricity
In order to solve this problem, screen protectors have also been released on the market to protect the screen from scratches. This layer of film plays a protective role but affects its original high-definition advantages.
In addition, many UV-blocking film products in the world need to go through the subsequent glue coating process. After multiple deep processes, they can absorb and convert ultraviolet light and short-wave blue light. In each glue coating process, due to the coating process The imperfection of the production environment and the cleanliness of the production environment are not up to standard, etc., which will cause different degrees of waste of materials
[0004] Therefore, the research and development of a new generation of screen protective film that can not only ensure better scratch resistance, but also avoid the reduction of screen clarity due to dirt has become the focus of current research, and it also has good application prospects and use value.

Abstract

The invention discloses a liquid crystal screen protective film and a preparation method, belonging to the technical field of screen protective films. The liquid crystal screen protective film comprises a base material layer, the upper surface of the base material layer is provided with a scratch-resistant layer, the upper surface of the scratch-resistant layer is provided with a dust removal layer, the lower surface of the base material layer is provided with a radiation-proof layer, and the radiation-proof layer is A release film is provided on the lower surface, and the substrate layer, the scratch-resistant layer, the radiation protection layer, and the radiation protection layer and the release film are connected through an adhesive layer. The preparation method comprises: coating an adhesive layer on the upper surface of the substrate layer, bonding a scratch-resistant layer on the upper surface of the adhesive; coating a dust release layer on the upper surface of the scratch-resistant layer; coating the lower surface of the substrate layer Cover the adhesive layer, then bond the radiation protection layer, then coat the adhesive layer on the lower surface of the radiation protection layer, and bond the release film. The protective film not only has good scratch resistance, but also has good radiation protection, electrostatic shielding and waterproof effects, provides multi-directional protection for liquid crystal screens, and has good application value.

Description

technical field [0001] The invention relates to the technical field of screen protection films, in particular to a liquid crystal screen protection film and a preparation method. Background technique [0002] With the continuous development of liquid crystal display technology, liquid crystal displays have been widely used in people's daily life. However, people gradually found that although this liquid crystal display has clear images and good use effects, it is extremely easy to be scratched and scrapped. , the screen has been widely used in mobile terminals such as mobile phones, and there are many protective products for the screen. Some protective film products have insufficient surface hardness and will also be scratched and scratched; although some protective film products have sufficient hardness, they cannot be very close to the screen. Good tightness, causing bubbles, affecting the appearance of the outside of the screen, and also affecting the display effect of th...
