specific Embodiment approach 1

[0015] Specific implementation mode one: the anti-reflection explosion-proof protective film of the mobile phone glass window protection screen in this embodiment is a multi-layer film structure, including a polyethylene plastic base layer 1, multiple adhesive layers, a glass film layer 3 and an explosion-proof layer 5, wherein the The polyethylene plastic base layer 1 described above is formed by blown film, and the multilayer film structure from top to bottom is the plastic base layer 1, the first adhesive layer 2, the tempered glass film layer 3, the second adhesive layer 4, the explosion-proof layer 5 and the second Three adhesive layers6.

[0016] The raw materials in the polyethylene plastic base layer described in this embodiment include 30-60 parts of low-density polyethylene (LDPE), 25-45 parts of linear low-density polyethylene (LLDPE) and 20-40 parts of metallocene medium-density polyethylene ( m-MDPE), which can be blown to form a single-layer film, or a three-laye...

specific Embodiment approach 2

[0017] Embodiment 2: This embodiment is different from Embodiment 1 in that one side of the third adhesive layer 6 is glued to the explosion-proof layer 5 , and the other side of the third adhesive layer 6 is glued to the release film.

[0018] In this embodiment, the thickness of the release film is 50-200 μm, and the material of the release film is PET film.

specific Embodiment approach 3

[0019] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that a hard coat layer or an oleophobic layer is provided on the surface of the polyethylene plastic base layer 1 .

[0020] The hard coat layer in this embodiment can be pasted on the (upper) surface of the plastic base layer by means of gluing, vapor deposition or sputtering. The hard coat layer is a hardened anti-scratch coating, such as polyurethane resin, and the thickness of the hard coat layer or oleophobic layer is 20-150 μm.

Abstract

The invention discloses an anti-reflection and anti-explosion protective film of a mobile phone glass view-window protective screen and a preparation method of the anti-reflection and anti-explosion protective film, relates to a protective film of the mobile phone glass view-window protective screen and a preparation method of the protective film, and aims to solve the problem that the light transmittance performance and the anti-explosion function of the anti-reflection and anti-explosion protective film of the mobile phone glass view-window protective screen are needed to be improved. The anti-reflection and anti-explosion protective film comprises a plastic basic layer, a first plastic layer, a reinforced glass film layer, a second plastic layer, an anti-explosion layer and a third plastic layer in sequence, wherein the polyethylene plastic basic layer is formed by film blowing and is prepared from low density polyethylene, linear low density polyethylene and metallocene medium density polyethylene. The high-light-transmittance-performance plastic basic layer is prepared by film blowing, so that the structure of the protective film is optimized, and the light transmittance rate of the anti-reflection and anti-explosion protective film can be up to 90 percent or above; and furthermore, when the reinforced glass film layer is broken, the reinforced glass film layer is only cracked instead of generating sputtering broken blocks, so that the use safety is improved.

Description

technical field [0001] The invention relates to a mobile phone glass window protective screen protective film and a preparation method thereof. Background technique [0002] Window protection screen is mainly used to decorate and protect the flat panel display of electronic products. It has the functions of anti-scratch, ultra-thin shockproof, screen protection and other functions. Among them, the liquid crystal display (LCD) on the mobile phone is usually composed of two pieces of ultra-thin ITO (indium tin oxide) glass with a thickness of 0.4-0.55mm. If the LCD is directly exposed, it is easy to be damaged during use. Therefore, the LCD of the existing mobile phone All of them are equipped with window protection screens that not only protect the LCD, but also play the role of beautiful decoration. There are two ways to make the existing window protection screen: 1. The way of mold opening and injection molding, also known as IMD technology (in-mold mosaic technology), the...
