Abstract
The utility model belongs to the technical field of the protection film, a PET is peeled off from type membrane to single face ultralight is disclosed for it is fixed with thick the disassembling the difficulty and disassembling the problem that there is battery surface damage in the in -process of existing of membrane to solve current battery. The utility model discloses a PET substrate layer, supreme precoat, pressure sensitive adhesive water layer and the release film layer of having set gradually is down followed to the upside of PET substrate layer, the downside of PET substrate layer is from last precoat, pressure sensitive adhesive water layer and the release paper layer of having set gradually under to. The utility model discloses has convenient removed operability to prevent dismantling in -process damage battery surface, and bonding reinforce, cold -resistant heat shock resistance have, simultaneously the utility model discloses have excellent combatting drop nature and shock resistance.
Description
Technical field
This utility model belongs to technical field of membrane and in particular to a kind of one side ultralight stripping PET mould release membrance.
Background technology
At present flexible-packed battery is due to must be fixedly arranged on drain pan when using, and generally adopted be conventional propylene
Sour adhesive tape, and if this adhesive tape is long-time bond after, appearance cannot be taken battery apart or be taken apart and cause battery surface during battery
Breakage, causes the problem of short circuit.
So that disassembling difficulty, layman is hardly possible to be disassembled, though professional be also required to special
Equipment is disassembled, and wastes time and energy, and with high costs.
Utility model content
This utility model in order to solve existing battery fixation film thick exist disassemble difficulty and disassemble during exist
The damaged problem of battery surface, and a kind of one side ultralight stripping PET mould release membrance is provided.
For solving above-mentioned technical problem, this utility model be employed technical scheme comprise that：
A kind of one side ultralight stripping PET mould release membrance it is characterised in that include PET base material layer, described PET base material layer upper
Side is disposed with precoated shet, pressure sensitive adhesive water layer and release film layer from bottom to up, the downside of described PET base material layer from top to bottom according to
Secondary it is provided with precoated shet, pressure sensitive adhesive water layer and off-style paper layer.
Further, the tensile strength of described PET base material layer is 50 80MPa.
Further, the elongation at break of described PET base material layer is in 500-800%.
Further, the thickness of described PET base material layer is 0.1mm or 0.15mm.
Compared with prior art, this utility model has the advantages that：
One side of the present utility model ultralight stripping PET mould release membrance includes PET base material layer, the upside of described PET base material layer from
Under supreme be disposed with precoated shet, pressure sensitive adhesive water layer and release film layer, the downside of described PET base material layer sets from top to bottom successively
It is equipped with precoated shet, pressure sensitive adhesive water layer and off-style paper layer.This utility model has easily removable operability, thus preventing from tearing open
Damage battery surface during unloading, and have that cohesive force is strong, cold-resistant heat shock resistance, simultaneously this utility model have excellent anti-
The property fallen and shock resistance.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure labelling：1st, PET base material layer, 2, precoated shet, 3, pressure sensitive adhesive water layer, 4, release film layer, 5, off-style paper layer.
Specific embodiment
With reference to embodiment, the utility model will be further described, and described embodiment is only that this practicality is new

The embodiment used by other that member is obtained under the premise of not making creative work, broadly falls into protection model of the present utility model
Enclose.
In conjunction with accompanying drawing, one side of the present utility model ultralight stripping PET mould release membrance includes PET base material layer 1, described PET base material
The upside of layer 1 is disposed with precoated shet 2, pressure sensitive adhesive water layer 3 and release film layer 4, under described PET base material layer 1 from bottom to up
Side is disposed with precoated shet 2, pressure sensitive adhesive water layer 3 and off-style paper layer 5 from top to bottom.
Further, the tensile strength of described PET base material layer is 50 80MPa.
Further, the elongation at break of described PET base material layer is in 500-800%.
Further, the thickness of described PET base material layer is 0.1mm or 0.15mm.
Manufacturing process of the present utility model is：From tensile strength in 50-80MPa, elongation at break is 500 800%
PET base material, the thickness of PET base material is generally 0.1mm or 0.15mm, using the both sides to PET base material layer for the slit coater
Carry out double spread precoated shet；Then pressure sensitive adhesive water layer is coated on PET one side by coating machine by the PET base material layer after processing
On mould release membrance, PET base material layer another side is equally coated in tableau release paper after pressure sensitive adhesive water layer after bake dry doubling tableau, and
Send into curing room and carry out cured, cured obtains the easy-to-draw adhesive tape of flexible-packed battery, and (i.e. one side of the present utility model surpasses
Light stripping PEHT mould release membrance).
