Description
Technical field
The present invention relates to a kind of mobile phone glass windows be protected screen protection cuticula and preparation method thereof.
Background technology
Windows be protected screen, is mainly used in the flat faced display of electronic product is decorated and protected, anti-zoned with surface
The functions such as wound, ultra-thin shockproof, screen protection.Liquid crystal display (LCD) wherein on mobile phone generally by two panels thickness be 0.4～
Ultra-thin ITO (tin indium oxide) the glass composition of 0.55mm, if LCD is directly exposed, is easy to damage in use, because
It is respectively arranged with above the LCD of this existing mobile phone and had both protected LCD, plays the form protective shield of attractive, decorative effect again.Existing form is prevented
The making of shield screen has two ways：1st, the mode of die sinking injection, also referred to as IMD technology (embedding technique in mould), the advantage of the method
Easily to realize curve form, shortcoming is high cost, and surface scratch resistance capability is poor；2nd, flat board CNC cutting modes, main material is
PC (Merlon) and PMMA (polymethyl methacrylate is commonly called as acryl) sheet material, its advantage are can flexibly to be cut according to figure
Cut, low cost, shortcoming is that surface scratch resistance capability and barrier propterty are poor.
In recent years, the electronic product with windows be protected screen, such as camera, mobile phone, media player, numerical digit phase
The display screen of machine, personal digital assistant, panel computer etc. is contacted with hard thing or receives the easy scratch windows be protected screen of external force, seriously
When even damage display screen, therefore people often can be pasted with protecting film on screen.
Existing electronic product screen protecting film, is typically all had substrate layer and glue-line, is attached substrate layer by glue-line
In mobile phone or the surface of electronic product screen.Existing screen protecting film, usual substrate layer are by one layer of plastic cement material or steel
The base material for changing glass is constituted, therefore only has the basic function of protecting screen glass not to be scraped off, simultaneously as general protect
The light transmittance of material, antireflection rate and the wear-resistant performance that cuticula is selected be not good, therefore screen can be caused to attach protecting film
Display image quality definition afterwards declines.Simultaneously because general protecting film only has scratch resistant function, it is impossible to increase the intensity of screen glass,
Therefore do not have functions that to prevent screen glass fragmentation.
But nowadays due to the fashion trend that mobile phone screen is in large size, increased windows be protected panel glass and clashed into
The risk of fragmentation, therefore the demand more and more higher of the protecting film with glass explosion prevention function.Simultaneously because electronic product screen solution
The lifting of the display parameters such as analysis degree and resolution, consumer for the requirement also pay attention to day by day of electronic product screen display image quality,
So the requirement of the optical property such as light transmittance for screen glass protecting film is also continuously increased.
The content of the invention
The invention aims to solve the light transmission and explosion-proof work(of existing mobile phone glass windows be protected screen protection cuticula
The problem that can have much room for improvement, and anti-reflection explosive-proof protector film of a kind of mobile phone glass windows be protected screen and preparation method thereof is provided.
Mobile phone glass windows be protected screen of the present invention is anti-reflection explosive-proof protector film is multi-layer film structure, including a polyethylene plastic cement base
Layer, multiple glue-lines, a glass film layers and an explosion-proof layer, wherein described polyethylene plastic cement basic unit is by blown film mode molding, multilamellar
Membrane structure is from top to bottom followed successively by plastic cement basic unit, the first glue-line, safety glass film layer, the second glue-line, explosion-proof layer and the 3rd glue-line.
The present invention the surface of plastic cement basic unit can also by sticker, evaporation or sputter etc. mode formed another plastic cement basic unit,
Oleophobic layer or hard membrane layer（Anti-scratch）Etc. functional layer, there is release layer in the surface mount of the 3rd glue-line.
The preparation method of mobile phone glass windows be protected screen of the present invention is anti-reflection explosive-proof protector film follow these steps to realize：
First, by weight by 30～60 parts of Low Density Polyethylenes（LDPE）, 25～45 parts of linear low density polyethylene（LLDPE）
With 20～40 portions of metallocene medium density polyethylenes（m-MDPE）Mix homogeneously, mixed material are squeezed in being transferred to blow molding machine
Go out blowfilm shaping, Jing coolings, cutting obtain polyethylene plastic cement basic unit；
2nd, the first surface of safety glass film after cleaning coats the first glue-line, by polyethylene plastic cement basic unit and the first glue-line
Paste；
3rd, the second surface of safety glass film after cleaning coats the second glue-line, and the one side of rupture pressure disc is glued with the second glue-line
Patch, then in another side the 3rd glue-line of coating of rupture pressure disc, form the anti-reflection explosive-proof protector film of mobile phone glass windows be protected screen.
The structure of the present invention optimization anti-reflection explosive-proof protector film of mobile phone glass windows be protected screen, using blowfilm shaping technique by original
Material heating particulates melt, and optimize the proportioning raw materials of plastic cement basic unit, and blown film prepares the polyethylene plastic cement basic unit of high transmission rate, and with this
The good safety glass film layer of body light transmission combines, so as to improve the integral light-transmitting performance of windows be protected screen protection cuticula, this
The light transmittance of the described anti-reflection explosive-proof protector film of mobile phone glass windows be protected screen of invention can reach more than 90%, in glass film layers
One side be also pasted with explosion-proof layer, explosion-proof layer is high-tensile macromolecule transparent membrane, and which can reduce safety glass film
The cracker meeting of layer, and when safety glass film layer fragmentation, ensure that toughened glass layer only has crackle broken without producing
The splashing of block, improves the safety in utilization of the anti-reflection explosive-proof protector film of mobile phone glass windows be protected screen, this is anti-reflection explosive-proof protector film
Preparation process is simple, it is adaptable to the experimentation of commercial production or protecting film.
