Description
Technical field
Touch-screen field is the utility model is related to, more particularly to a kind of antiacid diaphragm group easily torn.
Background technology
The full coating techniques of OGS are that the sensor of touch-screen is directly made in one layer of strengthened glass, this with traditional two layers
Structure (Sensor Glass：Sensor glass, Cover Glass protective cover sheet glass) touch-screen compare, it is more cost-effective,
It is lighter, thinner, optics penetrance is more preferable, and intensity index is higher, just turns into the key of domestic and international high-end smartphones at present
One of part.
Large stretch of glass touch screen is cut into small pieces glass cover-plate by touch-screen after the making of touch control line is completed, and is cut
The edge of touch-screen can have trickle crackle afterwards, and the avris wall of touch-screen four can have the sawtooth corner of out-of-flatness and intensity drops
It is low, therefore four avris wall mechanical strengths of the small sheet glass of intensive treatment raising need to be used.The chemical enhanced side of generally use at present
Formula (immersion of generally use strong base solution makes the Na atoms of glass surface be replaced as Ka atoms and makes the glass structure full), is entering
, it is necessary to erode the sawtooth corner of the out-of-flatness in side wall with strong acid before row is chemical enhanced, and glass is upper and lower in addition to side wall
Surface simultaneously need not strengthen and corrode, therefore, before being corroded and it is chemical enhanced before, in glass upper and lower surface can paste one layer
Antiacid diaphragm, it is chemical enhanced it is complete after antiacid film is removed again, during acid liquid corrosion, can have bubbling phenomenon, easily lead
Antiacid film is caused in edge and touch-screen degumming or is separated so as to cause touch-screen overetched bad phenomenon occur, therefore will
Ask antiacid film to possess higher viscosity, because antiacid film viscous force is general all larger, for large scale OGS (8 cun of ＞), antiacid film with
OGS surface bonding areas are big, after intensive treatment, remove antiacid film operation difficulty, influence production efficiency.
In the prior art there is a method in which the mode of intensive treatment is using UV solution glue-type antiacid film (UV pre-irradiations viscosity
Greatly, prevent edge from coming unglued, viscosity reduces after UV irradiations, conveniently removes operation) intensive treatment is carried out, because the processing procedure is secondary in completion
Also needed to after intensive treatment carry out UV irradiation with reduce antiacid film viscosity facilitate dyestripping, it is necessary to expend more multiple-energy-source and manpower into
This.Therefore, a kind of scheme is needed in the prior art to solve this difficult problem of large scale OGS dyestrippings.
Utility model content
The purpose of this utility model be to overcome above-mentioned the deficiencies in the prior art, the utility model proposes it is a kind of easily tear it is anti-
Sour diaphragm.
To achieve the above object, the utility model uses following technical proposals：
A kind of antiacid diaphragm easily torn, including the substrate layer 1 to fit together is with hiding glued membrane 3, the face of the substrate layer
Product is more than or equal to touch-screen 5 and can all cover touch screen upper surface or lower surface, and substrate layer is used to be bonded with hiding glued membrane
One side be provided with antiacid adhesive-layer 2, it is described to hide that the glued membrane one side opposite with antiacid adhesive-layer is inviscid, and the area for hiding glued membrane is small
In touch-screen area and hide the centre position that glued membrane is adhered to by antiacid adhesive-layer substrate layer so that the antiacid adhesive-layer
The region contacted with touch-screen forms three-back-shaped housing, and the antiacid adhesive area of three-back-shaped frame structure is used to make antiacid adhesive-layer
Bonded together with touch screen upper surface or lower surface edge area so as to prevent the upper and lower surface of touch-screen by acid liquid corrosion, to be located at
The screening glued membrane in substrate layer centre position is sandwiched between antiacid adhesive-layer and touch-screen, for reducing antiacid viscose glue and touch-screen
Total contact area and be easy to dyestripping.
Further, it is described to hide that glued membrane is unilateral compared with substrate layer inside contracts 20~100mm.
Preferably, the substrate layer is PO (expoxy propane) base material, PET base material or PO and PET composite base materials, and the base
Material thickness degree is 100~200 μm.
Preferably, the adhesive that the antiacid adhesive-layer uses is acrylic resin adhesive, and the antiacid adhesive-layer
Peel strength be 35~60g/25mm, thickness is 20~50 μm.
Preferably, it is characterised in that the thickness for hiding glued membrane is 20~50 μm.
Preferably, the diaphragm group also includes mould release membrance 4, and mould release membrance is used to be labelled to touch with hiding glue-line in substrate layer
It is bonded before screen surfaces with substrate layer.
Preferably, the thickness of the mould release membrance is 50~75 μm.
Preferably, the screening glued membrane uses PET film.
Preferably, the substrate layer is additionally provided with handle.
The utility model at least has the advantages that：Two-sided no glue PET is hidden glued membrane and is attached at base by the utility model
One side of the material layer with antiacid adhesive-layer, the glue surface that substrate layer contacts with touch-screen are in three-back-shaped, and antiacid diaphragm is covered on and adopted
With the upper and lower surface of OGS touch screen, diaphragm can ensure that the upper and lower surface of the touch-screen when the side of touch-screen four is strengthened is not invaded
Erosion.After the completion of intensive treatment, because the not whole face of touch-screen upper and lower surface is bonded with glue surface, only three-back-shaped glue surface is pasted with touch-screen
Close, therefore be easy to dyestripping during dyestripping operation.The utility model, which has, improves operating efficiency, human cost is saved, beneficial to the spy of production
Point.
