Description
Technical field
This utility model belongs to protecting film field, is specifically related to a kind of high-weatherability processing procedure protecting film.
Background technology
Electronic product, in the course of processing, the most all can use protecting film.Such as computer monitor glass-cutting, polishing, glass
The micro etch of glass work piece cut trace, notebook computer light guide plate, light polarizing film all can paste guarantor in its surface in processing assembling process
Cuticula, it is to avoid workpiece scratches or in the acid or alkali environment corrosion to workpiece.Traditional processing procedure protecting film mainly uses PP film or PET
Film, this kind of protecting film acid-alkali-corrosive-resisting is poor, is in acid or alkali environment for a long time and easily corrodes, and drops workpiece protective value
Low, secondly non-refractory, inevitably produces amount of heat in work piece cut bruting process, and PP film or PET film are to height
Temperature poor resistance, heated time is long easily occurs that crimping shrinks, and in being in high temperature or acid or alkali environment for a long time, PP with
Easily there is problems such as turning to be yellow, aging toughness is low in PET film.
Fluorine plastic film is the thin film that fluorothene high polymer is made, this film chemical stability, water preventing ability, heat stability
Preferably, can be in for a long time in liquid or hot environment, be difficult to aging, weatherability is preferable.It is wide in solar energy back veneer material
General application.Currently used fluorine plastic film mainly has polyvinyl fluoride, Kynoar, polytrifluorochloroethylene etc..By fluoroplastics
Be combined with conventional PET film and can be effectively increased the high-temperature stability of protecting film, liquid barrier property etc..
Summary of the invention
Problem to be solved in the utility model is: provide a kind of high-weatherability processing procedure protecting film.
For solving the problems referred to above, the technical scheme that this utility model provides is: a kind of high-weatherability processing procedure protecting film, including
The PET base material layer overlapped successively, adhesive layer and release film layer, in the technical program, also include weather-proof thin layer, described
Weather-proof thin layer is located between described PET base material layer and adhesive layer.This protecting film on the basis of conventional PET protection film,
Setting up a weather-proof thin layer between substrate layer and adhesive layer, weather-proof thin layer weatherability is high, and stable chemical nature is high temperature resistant,
In soda acid and hot environment, ageing resistace is difficult to well corrosion-deformation, and this weather-proof coat block-water performance is preferable, liquid
State permeability is relatively low, in soda acid liquid processing environment, it is possible to prevent acid & alkali liquid from infiltrating into surface of the work by protecting film, effectively
Protect face to separate with acid & alkali liquid workpiece, protective value is reliable；And fluorine plastic film processing adhesion property is preferable, easily with
PET basic unit bonding is compound.
Further, described weather-proof thin layer is fluorine plastic film.
Further, described weather-proof thin layer is in polyvinyl fluoride, polyvinylidene difluoride film or polytrifluorochloroethylene
Kind, these several fluorine plastic film use costs are relatively low.
Further, described adhesive layer is acid and alkali-resistance adhesive layer.Adhesive layer is that acidproof alkaline further increases
The resistance to acids and bases of protecting film.
Further, described weather-proof thin film layer thickness is 5～40 microns.
Further, described release film layer is arbitrary in polyethylene film, polypropylene film, mylar or natural paper
Kind.
The utility model has the advantages that:
This protecting film, on the basis of conventional PET protection film, sets up a weather-proof thin film between substrate layer and adhesive layer
Layer, weather-proof thin layer weatherability is high, and stable chemical nature, high temperature resistant, in soda acid and hot environment, ageing resistace is the most not
Perishable deformation, and this weather-proof coat block-water performance is preferable, liquid permeability is relatively low, in soda acid liquid processing environment,
It is prevented from acid & alkali liquid and infiltrates into surface of the work by protecting film, effectively protect face to separate with acid & alkali liquid workpiece, protectiveness
Can be reliable；And fluorine plastic film processing adhesion property is preferable, easily it is combined with PET basic unit bonding；Adhesive layer uses simultaneously
Acid and alkali-resistance adhesive layer, further increases the acid-proof alkaline of protecting film.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment
Fig. 1 is the structural representation of this high-weatherability processing procedure protecting film.
Wherein: 1.PET substrate layer；2. adhesive layer；3. release film layer；The most weather-proof thin layer.
Embodiment 1: high-weatherability processing procedure protecting film as shown in Figure 1, including the PET base material layer 1 overlapped successively, adhesive
Layer 2 and release film layer 3, also include that weather-proof thin layer 4, described weather-proof thin layer 4 are located at described PET base material layer 1 and adhesive layer 2
Between, weather-proof thin layer 4 is fluorine plastic film.Weather-proof thin layer 4 is selected from polyvinyl fluoride, polyvinylidene difluoride film or poly-trifluoro chlorine
One in ethylene.Adhesive layer 2 is acid and alkali-resistance adhesive layer.Weather-proof thin layer 4 thickness is 5～40 microns.Release film layer 3 selects
In polyethylene film, polypropylene film, mylar or natural paper any one.
Examples detailed above only for technology of the present utility model design and feature are described, its object is to allow and is familiar with technique
