Abstract
The utility model discloses a protective film for easy-peel glass. The protective film comprises a polypropylene base material film on the upper and lower surfaces of which metal layers are respectively coated, wherein a pressure-sensitive adhesive layer is coated on the other surface of the metal layer positioned on the lower surface of the polypropylene base material film; a release material layer is attached to the other surface of the pressure-sensitive adhesive layer; multiple thermal expansion microspheres are uniformly distributed in the pressure-sensitive adhesive layer; the diameter of each thermal expansion microsphere is 9-15 micrometers. The protective film for the easy-peel glass disclosed by the utility model has high cohesive property at low temperature, and the adhesive property disappears at high temperature, so that small electronic components are effectively recovered, adhesive residues are avoided, specular reflection is reduced, and the perspective rate is improved.
Description
Technical field
The utility model relates to a kind of plastic sheeting that adheres to glass surface, relates in particular to a kind of easy-stripping type glass diaphragm.
Background technology
Current glass and vehicle glass plastic sheeting have of all kinds, have and for security purpose, are pasted on merely the water white transparency rupture pressure disc on glass and vehicle glass; There is shades of colour (for example coffee-like, sky-blue) can play shading, explosion-proof vehicle glass film; although these vehicle glass films play a role to solving above-mentioned existing problems; but also exist shortcoming and defect; unsatisfactory; mainly when needing replacing or processing original diaphragm; because adhesion coating is affixed on affixed object for a long time, there will be cull phenomenon, be difficult for processing.So, how to be convenient for changing the striving direction that adhering film to glass becomes those of ordinary skills.
Summary of the invention
The utility model provides a kind of easy-stripping type glass diaphragm; this easy-stripping type glass has good viscosity during with diaphragm low temperature, thereby adhesive property disappears and effectively reclaims miniature electric components and parts during high temperature, avoids cull; and reduced mirror-reflection, improved perspective rate.
For achieving the above object, the technical solution adopted in the utility model is: a kind of easy-stripping type glass diaphragm, comprises the upper and lower surface polypropylene base film of metal-coated layer respectively; Another surface of metal level that is positioned at described polypropylene base film lower surface is coated with a pressure-sensitive adhesive layer, and another surface label of this pressure-sensitive adhesive layer is covered with separated type material layer; In described pressure-sensitive adhesive layer, be evenly distributed with some microspheres, the diameter of this microspheres is 9～15um.
In technique scheme, further improved technical scheme is as follows:
1. in such scheme, the contact-making surface of described pressure-sensitive adhesive layer and separated type material layer has several salient points.
2. in such scheme, described pressure sensitive adhesive layer is esters of acrylic acid adhesive layer or organosilicon tack coat.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the utility model easy-stripping type glass diaphragm; in its pressure-sensitive adhesive layer, be evenly distributed with some microspheres; the diameter of this microspheres is 9～15um; make prepared pressure-sensitive tape when lower than 60 ℃; there is good viscosity; when temperature, higher than 110 ℃, toast after 5 minutes, this pressure sensitive adhesive loses adhesive property.This pressure sensitive adhesive changes the viscosity size variation of adhesive tape by variations in temperature interval, possess splendid cohesive and thermally strippable, at electronic unit manufacturing process, the aspect such as temporary fixed, has good application prospect;
2, the utility model easy-stripping type glass diaphragm, its two metal layers by polypropylene base divided thin film every, reduced mirror-reflection, make personnel below of composite membrane can clearly see the situation of composite membrane outside, so perspective rate is high;
Accompanying drawing explanation
Accompanying drawing 1 is the utility model easy-stripping type glass diaphragm structural representation.
In above accompanying drawing: 11, metal level; 12, metal level; 2, polypropylene base film; 3, separated type material layer; 4, pressure-sensitive adhesive layer; 5, contact-making surface; 51, salient point; 6, microspheres.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment 1: a kind of easy-stripping type glass diaphragm, comprises the upper and lower surface polypropylene base film 2 of metal-coated layer 11,12 respectively; Metal level 12 another surfaces that are positioned at described polypropylene base film 2 lower surfaces are coated with a pressure-sensitive adhesive layer 4, and these pressure-sensitive adhesive layer 4 another surface labels are covered with separated type material layer 3; In described pressure-sensitive adhesive layer 4, be evenly distributed with some microspheres 6, the diameter of this microspheres 6 is 11um.
Above-mentioned pressure-sensitive adhesive layer 4 has several salient points 51 with the contact-making surface 5 of separated type material layer 3.
Above-mentioned microspheres, can be akzonobel company microspheres, and it has flexible shell and contains the low-boiling point materials such as iso-butane, propane, pentane.
Embodiment 2: a kind of easy-stripping type glass diaphragm, comprises the upper and lower surface polypropylene base film 2 of metal-coated layer 11,12 respectively; Metal level 12 another surfaces that are positioned at described polypropylene base film 2 lower surfaces are coated with a pressure-sensitive adhesive layer 4, and these pressure-sensitive adhesive layer 4 another surface labels are covered with separated type material layer 3; In described pressure-sensitive adhesive layer 4, be evenly distributed with some microspheres 6, the diameter of this microspheres 6 is 14um.
Above-mentioned pressure-sensitive adhesive layer 4 has several salient points 51 with the contact-making surface 5 of separated type material layer 3.
Above-mentioned microspheres, can be akzonobel company microspheres, and it has flexible shell and contains the low-boiling point materials such as iso-butane, propane, pentane.
While adopting above-mentioned easy-stripping type glass to use diaphragm; in its pressure-sensitive adhesive layer, be evenly distributed with some microspheres; the diameter of this microspheres is 9～15um; make prepared pressure-sensitive tape when lower than 60 ℃; there is good viscosity; when temperature, higher than 110 ℃, toast after 5 minutes, this pressure sensitive adhesive loses adhesive property.This pressure sensitive adhesive changes the viscosity size variation of adhesive tape by variations in temperature interval, possess splendid cohesive and thermally strippable, at electronic unit manufacturing process, the aspect such as temporary fixed, has good application prospect; Secondly, its two metal layers by polypropylene base divided thin film every, reduced mirror-reflection, make composite membrane personnel below can clearly see the situation of composite membrane outside, so perspective rate is high.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
