Abstract
The utility model discloses a heat-peelable double-base film. The heat-peelable double-base film comprises a polyethylene base film, and a polypropylene base film of which the lower surface is coated with a metal layer, wherein the polyethylene base film is adhered to the metal layer of the polypropylene base film through an adhesive layer; a pressure-sensitive adhesive layer is arranged on the lower surface of the polyethylene base film; the other surface of the pressure-sensitive adhesive layer is coated with a peelable material layer; a plurality of air holes are formed in the adhesive layer; the diameter of the air holes is 3-18 microns; a plurality of heat-expandable microspheres are uniformly distributed in the pressure-sensitive adhesive layer. When heated, the heat-peelable double-base film can form various shapes such as a convex arc or a pot so as to be adhered to various spherical surfaces or specially-shaped glass conveniently, so that antistatic matte film can be uniformly peeled from an adhered surface at high temperature and has no residue.
Description
Technical field
The utility model relates to a kind of pad pasting, relates in particular to a kind of bi base material pad pasting of heat-peelable.
Background technology
The material such as plastic plate, sheet metal is in carrying and use procedure, and its surface is easily subject to contact stain(ing) or polishing scratch scratches, and makes it to avoid damage and pollutes so conventionally adopt protective membrane to cover its surface.In prior art, protective membrane used is substantially all planar protection film, and it comprises substrate layer, adhesive coating and release layer under normal circumstances.Described substrate layer is generally the materials such as poly-carbon polyester (PC), polyethylene (PE), PET, orientation stretching polypropylene (OPP) or aromatic polyester and forms, the primary structure layer that substrate layer is protective membrane; Adhesion laminating floats on a side of substrate layer, is conventionally made up of the institute such as polymkeric substance or acrylate copolymer of containing organoalkoxysilane, in order to substrate layer is posted up to the body surface of wish protection; And release layer is for the protection of the protective membrane under unused state, when use, release layer is removed and sticked to body surface.
This common planar protection film forms by three layers, has solved the reflective of existing protection pad pasting and the technical problem of dazzling light, becomes the direction that those of ordinary skill in the art make great efforts.
Summary of the invention
The utility model provides a kind of bi base material pad pasting of heat-peelable, the bi base material pad pasting of this heat-peelable has ensured to heat and has formed convex or different shape such as pot type etc., so that paste various spheres or shaped face glass, make antistatic cloudy surface pad pasting in the time of high temperature, depart from equably sticky surface and noresidue.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bi base material pad pasting of heat-peelable, comprise the polypropylene base film of the metal-coated layer of polyethylene base material film and lower surface, the metal level of described polyethylene base material film and polypropylene base film is bonding by an adhesive-layer; Described polyethylene base material film lower surface has a pressure-sensitive adhesive layer, and another surface label of this pressure-sensitive adhesive layer is covered with separated type material layer; In described adhesive-layer, be evenly distributed with some pores, the diameter of this pore is 3～18 microns, is evenly distributed with several microspheres in described pressure-sensitive adhesive layer.
In technique scheme, further improved technical scheme is as follows:
1,, in such scheme, the contact surface of described pressure-sensitive adhesive layer and separated type material layer has several salient points.
2,, in such scheme, described separated type material layer is off-style paper layer or release film layer.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the bi base material pad pasting of the utility model heat-peelable, take the polypropylene base film combinations of polyethylene base material film and the metal-coated layer of metal-coated layer, overcome the technological deficiency of taking single base material in prior art, both toughness, plasticity-had been realized, having ensured to heat forms the different shape such as convex or pot type, so that paste various spheres or shaped face glass.
2, the bi base material pad pasting of the utility model heat-peelable, in its pressure-sensitive adhesive layer, be evenly distributed with some microspheres simultaneously, both made prepared pressure-sensitive adhesive tape when lower than 60 DEG C, there is good viscosity, when temperature is toasted after 5 minutes higher than 110 DEG C, this pressure sensitive adhesive loses adhesiveproperties, the existence of adhesive-layer inner air vent also makes antistatic cloudy surface pad pasting in the time of high temperature, depart from equably sticky surface and noresidue, with also it has solved the reflective of existing protection pad pasting and the technical problem of dazzling light, form certain mist degree, the comfort level of vision and the optical property of product are improved.
Brief description of the drawings
Accompanying drawing 1 is the bi base material film structure schematic diagram of the utility model heat-peelable.
In above accompanying drawing: 1, metal level; 2, polyethylene base material film; 3, polypropylene base film; 4, adhesive-layer; 5, pore; 6, pressure-sensitive adhesive layer; 61, contact surface; 62, salient point; 7, separated type material layer; 8, microspheres.
Embodiment
