Abstract

The utility model discloses a matte protection film with double base materials. The film comprises a polyethylene base material thin film of which the upper surface is plated with a metal layer and a polypropylene base material thin film of which the lower surface is plated with a metal layer, wherein the metal layer of the polyethylene base material thin film is adhered with the metal layer of the polypropylene base material thin film through an adhesive layer; a pressure-sensitive adhesive layer is arranged on the lower surface of the polyethylene base material thin film , and the other surface of the pressure-sensitive adhesive layer is pasted with a separated material layer; a plurality of air holes are uniformly formed in the adhesive layer, the diameter of each air hole is from 3 to 18 microns, and a plurality of convex points are formed in the contact surface between the pressure-sensitive adhesive layer and the separated material layer. The matte protection film with the double base materials, provided by the utility, realizes the toughness and the plasticity, and the stiffness is also improved; besides, the technical problems of the light reflection and dazzle of the existing protection pasted film are solved, so that the optical performance of products is improved, and the requirements of users are satisfied.

Description

Bi base material cloudy surface protective membrane
Technical field
The utility model relates to a kind of protective membrane, relates in particular to a kind of bi base material cloudy surface protective membrane.
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 so 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 cloudy surface protective membrane, and this bi base material cloudy surface protective membrane had both been realized toughness and plasticity-, had improved again its deflection; And solve the reflective of existing protection pad pasting and dazzled the technical problem of light, thereby having improved the optical property of product, having met client's requirement.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bi base material cloudy surface protective membrane, comprise the polyethylene base material film of the metal-coated layer of upper surface and the polypropylene base film of the metal-coated layer of lower surface, described polyethylene base material thin film metal layer and polypropylene base thin film metal layer are 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.
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 utility model bi base material cloudy surface protective membrane; in ensureing low reflective single plane fluoroscopy; 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 utility model bi base material cloudy surface protective membrane; in its adhesive-layer, be evenly distributed with some pores, the diameter of this pore is 3~20 microns, the technical problem that it has solved the reflective of existing protection pad pasting and has dazzled light; thereby improve the optical property of product, met client's requirement.
Brief description of the drawings
Accompanying drawing 1 is the utility model bi base material cloudy surface protective membrane structural representation.
In above accompanying drawing: 11, metal level; 12, 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.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
