Abstract
The utility model discloses a self-stripping antistatic pasting film. The self-stripping antistatic pasting film comprises a polyethylene film and a polyethylene terephthalate (PET) film, wherein the polyethylene film is glued and adhered to the PET film through a polyurethane structure; an antistatic coating layer 8 is coated on the upper surface of the polyethylene film 1; a pressure-sensitive adhesive layer is coated on the lower surface of the PET film; a release material layer is adhered to the other surface of the pressure-sensitive adhesive layer; a plurality of thermal expansion microballoons are uniformly distributed in the pressure-sensitive adhesive layer; the average diameter of the thermal expansion microballoon is 10-40 microns; and a contact surface of the pressure-sensitive adhesive layer with the release material layer is provided with a plurality of salient points. The self-stripping protective pasting film is high in stickiness at a low temperature, so that the surface of the material can be effectively protected; and the adhesion performance is eliminated so as to conveniently strip the antistatic pasting film when the self-stripping protective pasting film is at a high temperature.
Description
Technical field
The utility model relates to a kind of protection pad pasting, relates in particular to a kind of from peeling off the antistatic protection pad pasting.
Background technology
In the processing cutting process of the materials such as sheet metal, plastic plate, its surface easily is subject to contact stain(ing) or polishing scratch scratches, and makes it to avoid damage and pollutes so usually adopt protective membrane to cover its surface.After the processing cutting process finished, protective membrane can be removed.Therefore how to peel off easily and efficiently the protection pad pasting, improving production efficiency is to be badly in need of the technical problem of solution in the processing cutting process.
Summary of the invention
The utility model provides that a kind of this has viscosity preferably when peeling off antistatic protection pad pasting low temperature from peeling off the antistatic protection pad pasting, protecting materials surface effectively, thus adhesiveproperties disappears and can peel off easily during high temperature.
For achieving the above object; the technical solution adopted in the utility model is: a kind of from peeling off the antistatic protection pad pasting; comprise polyethylene film and PET film; bonding by PU structural adhesive between described polyethylene film and PET film; the lower surface of described PET film is coated with pressure-sensitive adhesive layer; another surface label of this pressure-sensitive adhesive layer is covered with the separated type material layer; be evenly distributed with several microspheres in described pressure-sensitive adhesive layer; the mean diameter of this microspheres is 10～40 μ m, and the contact surface of described pressure-sensitive adhesive layer and separated type material layer has several salient points.
In technique scheme, further improved technical scheme is as follows:
1, in such scheme, described separated type material layer is off-style paper layer or release film layer.
2, in such scheme, described pressure-sensitive adhesive layer is the esters of acrylic acid adhesive layer.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the utility model is from peeling off the antistatic protection pad pasting; be evenly distributed with some microspheres in described pressure-sensitive adhesive layer; the mean diameter of this microspheres is 10～40 μ m; make prepared pressure sensitive adhesive lower than 60 ℃ the time; has good viscosity; after temperature was toasted 3 minutes higher than 90 ℃, this pressure sensitive adhesive lost adhesiveproperties.Substrate layer adopts the PE/PET matrix material, and during intensification, PE contraction drive PET is curling, coordinates microballoon to expand, and is therefore rapider from peeling rate.This pressure sensitive adhesive changes the viscosity size of protection pad pasting by temperature variation, possess splendid binding property and from stripping performance.
2, the utility model is from peeling off the antistatic protection pad pasting, and the contact surface of pressure-sensitive adhesive layer and separated type material layer has several salient points, the discharge of gas when being conducive to fit, thereby the generation of having avoided bubble and circle to print.
Description of drawings
Accompanying drawing 1 is peeled off antistatic protection pad pasting schematic diagram certainly for the utility model.
In above accompanying drawing: 1, polyethylene film; 2, contact surface; 3, PET film; 4, PU structural adhesive; 5, pressure-sensitive adhesive layer; 6, separated type material layer; 7, microspheres; 8, antistatic coating.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
