Abstract
The utility model discloses a peelable matte double-base film. The peelable matte double-base film comprises a polyethylene base film and a polypropylene base film, wherein the polyethylene base film is adhered to the polypropylene base film through an adhesive layer; a plurality of air holes are formed in the 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 heat-expandable microspheres are uniformly distributed in the pressure-sensitive adhesive layer; the diameter of the heat-expandable microspheres is 3-18 microns; the average diameter of the air holes is 4-9 microns. The peelable matte double-base film has relative good adhesion at low temperature and has no adhesive property at high temperature, so that damage to glass and residual adhesive are effectively avoided; the peelable matte double-base film has a certain haze, so that the visual comfort and optical properties of a product are improved.
Description
Technical field
The utility model relates to a kind of protective membrane, relates in particular to a kind of peelable cloudy surface bi base material pad pasting.
Background technology
The material such as glass, plastic plate 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 so common planar protection film forms by three layers, and along with the variation of other situation of humidity, temperature and surrounding environment, adhesive coating easily makes moist or is subject to chemical reaction and produces the phenomenon that substrate layer comes off; In the time that needs are changed or are processed original protective membrane, because being affixed on affixed object for a long time, adhesive coating there will be cull phenomenon, be difficult for processing.
Summary of the invention
The utility model provides a kind of peelable cloudy surface bi base material pad pasting, when this peelable cloudy surface bi base material pad pasting low temperature, has good viscosity, thereby adhesiveproperties disappears and effectively avoided damage and the cull to glass when high temperature; And there is certain mist degree, improved the comfort level of vision and the optical property of product.
For achieving the above object, the technical solution adopted in the utility model is: a kind of peelable cloudy surface bi base material pad pasting, comprise polyethylene base material film and polypropylene base film, described polyethylene base material film and polypropylene base film are bonding by an adhesive-layer, and this adhesive-layer contains several pores; 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 pressure-sensitive adhesive layer, be evenly distributed with several microspheres.
In technique scheme, further improved technical scheme is as follows:
1,, in such scheme, the diameter of described microspheres is 3～18 μ m.
2,, in such scheme, described pore mean diameter is 4～9 μ m.
3,, 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:
The peelable cloudy surface bi base material of the utility model pad pasting, its adhesive-layer contains several pores, in pressure-sensitive adhesive layer, be evenly distributed with several microspheres, both made prepared pressure-sensitive adhesive tape when lower than 60 DEG C, there is good viscosity, toast after 5 minutes higher than 110 DEG C when temperature, this pressure sensitive adhesive loses adhesiveproperties; With also it has solved the reflective of existing protection pad pasting and the technical problem of dazzling light; form certain mist degree; improve the comfort level of vision and the optical property of product, met client's requirement, there is good application prospect at electronic unit manufacturing process, the aspect such as temporary fixed.
