Abstract
The utility model provides a multilayer film tape structure. The structure comprises a release protective layer and at least two layers of films, wherein adhesive is applied between the adjacent films, as well as between the top layer film and the release protective layer; an anti-static layer is coated on the bottom surface of the bottom layer film; the films adopt polyester films or polyimide films; the adhesive adopts pressure-sensitive adhesive; and the release protective layer adopts a piece of silicon-coated release paper, a silicon-coated release film or a piece of PE laminated silicon-coated release paper. The multilayer film tape structure can be used for edge encapsulation of a liquid crystal display panel, has the benefits of persistent tension resistance, no generation of adhesive residue and capability of effectively preventing tape edge from upwarping, facilitating re-encapsulation and effectively protecting the liquid crystal display panel from electrostatic damages, and the tape can be well matched with liquid crystal displays in different colors for encapsulation.
Description
Technical field
The utility model relates to a kind of adhesive tape structure, especially relates to a kind of adhesive tape structure with multilayer film, in particular, relates to a kind of panel of LCD edge seal multilayer film adhesive tape structure.
Background technology
Along with the high speed development of information age, people improve day by day to the visual requirement of consumption electronic product, and high-quality display window has obtained favor widely.Display image is clear, picture is soft, volume is little because of having for liquid-crystal display, in light weight, power saving, radiation are low, be easy to carry about with one, do not hinder advantages such as eyes obtains more and more widely application.
The general plastic cement frame fixed panel perimeter that adopts of panel of LCD encapsulation, there is following shortcoming in this encapsulation fixed form: the operation sequence complexity, processing characteristics is bad, cost is higher, and the panel construction complexity after the encapsulation, volume is big, and weight is big, and poor sealing between plastic cement frame and the panel, outward appearance are very not attractive in appearance yet.The panel of LCD encapsulation of prior art is also progressively abandoned using traditional plastic cement frame fixed panel, and selected to use film substrate single face adhesive tape encapsulation fixed panel periphery, makes indicating meter more attractive in appearance, and is light.But the subject matter that this method exists at present is, because the film substrate that need select for use of encapsulated liquid crystal panel should have requirements such as high strength, high tenacity, wear-resistant, insulativity, be generally polyester (PET), polyimide materials such as (PI), and thickness is more than 0.05 millimeter.The deflection of these materials increases with the increase of film thickness, thereby then has stronger lasting tension force than the thick film base material at flexure plane, and causing with this film is the easy perk of tape edge of base material; In order to guarantee that perk does not take place adhesive tape, need to increase the viscosity of adhesive tape usually, but can increase the possibility that cull occurs again like this, inconvenience is technical problem such as encapsulation operation again.
Therefore, develop and a kind ofly can resist lasting tension force, can effectively prevent the tape edge perk, do not produce cull again, the convenient panel of LCD edge seal adhesive tape of encapsulation operation again is still this area urgent problem.
Summary of the invention
The purpose of this utility model provides and a kind ofly can resist lasting tension force, and cull is not stayed in not perk of tape edge again, convenient a kind of adhesive tape structure of encapsulation again.
The technical solution of the utility model is: a kind of multilayer film adhesive tape structure comprises release protective layer, also comprises double-layer films at least, is coated with sizing agent between the adjacent films and between the film of top layer and the release protective layer.
Be coated with antistatic backing on the film basal surface of bottom.
Described film is polyester film or Kapton.
Described sizing agent is a pressure sensitive adhesive.
Described release protective layer is release paper coated with silicon, be coated with the silicon release film or PE drenches the film release paper coated with silicon.
Advantage and the positively effect that the utlity model has are:
1, anti-lasting tension force can effectively prevent the tape edge perk.
2, do not produce cull, convenient encapsulation operation again.
3, effectively protect not destruction by electrostatic field of panel of LCD.
4, adhesive tape has diversified color outward appearance, can well mate the liquid-crystal display package application of different colours.
