Abstract
The utility model discloses an anti electrostatic protection membrane of persistence (b), (b) is including substrate layer (1), the both sides of substrate layer (1) are scribbled respectively and are covered with antistatic backing (2), antistatic backing (2) the outside coating have pressure sensitive adhesive layer (3), pressure sensitive adhesive layer (3) by interval pressure sensitive adhesive layer piece (30) in turn with prevent static granule (31) constitution, pressure sensitive adhesive layer (3) outside scribble and be covered with from type layer (4), compared with the prior art, the utility model, carry out antistatic finish through the surface to the substrate for the protection film can not produce static when rubbing with other article, pressure sensitive adhesive layer piece that pressure sensitive adhesive layer is equalled by the interval with prevent that the static granule constitutes, the pressure sensitive adhesive layer piece structurally ensures to have the good power of peeling off from the type layer, prevents that the static granule makes also not produce static from the type layer when peeling off, finally realizes permanent anti -static function.
Description
Technical field
The utility model relates to a kind of protective membrane for the electronic applications such as electronics, flat-panel display device, a kind of persistence Antistatic protective film particularly in this field.
Background technology
In recent years, along with the large-scale promotion application of unicircuit, electronic product miscellaneous has become an indispensable part in people's life.Because the circuit of ic component reduces, withstand voltage reduction, circuit area reduces, make weakening of the resistance to electrostatic impact ability of device, static electric field (StaticElectricField) and electrostatic induced current (ESDcurrent) all may become the fatal killer of these high-density components and parts.Electrostatic adhesion dust, changes the impedance between electronic circuit, can affect function and the life-span of product; Electrostatic field may destroy insulation or the conductor of element, and element can not be worked; The heat that the electric field of moment or electric current produce all can make element injured, affects the electronic product life-span, even causes it to damage completely.
But traditional antistatic protection film generally only has glue-line or rete anti-electrostatic, can only accomplish the effect of an anti-electrostatic.And in practice, when being peeled off by pressure-sensitive adhesive layer, or very easily produce electrostatic when there is friction in electronic product moving process, thus cause electronic product impaired or get dirty.
Utility model content
The utility model provides a kind of permanent antistatic protective membrane, efficiently solve exist in prior art protective membrane poor electric conductivity, easily produce the technical problems such as electrostatic, easily harm electronic component.
For solving the problem, the utility model realizes by the following technical solutions:
A kind of persistence Antistatic protective film; comprise substrate layer; the both sides of described substrate layer are coated with antistatic backing respectively; pressure-sensitive adhesive layer is coated with outside described antistatic backing; the pressure-sensitive adhesive layer block that described pressure-sensitive adhesive layer is replaced by interval and anti-electrostatic particle are formed, and are coated with release layer outside described pressure-sensitive adhesive layer.
Preferably, described substrate layer material is the one in PET or OPP.
Preferably, described substrate layer thickness is 55um ~ 130um.
Preferably, described antistatic backing surface impedance is 10
4~
11Ω.
Preferably, described antistatic backing is made up of one or more of vinylformic acid, modified acrylic acid, type siloxane and modified siloxane family macromolecule antistatic agent, and the coat-thickness of described antistatic backing is 0.5-1.5um.
Preferably, described anti-electrostatic particle is made up of one or more of gathering in sulphonic acids, polythiophene class, silver powder or nano level nickel powder particle, and the particle diameter of described anti-electrostatic particulate is 0.10um-0.80um.
Preferably, described release layer peeling force is 5-100g.
The beneficial effects of the utility model are: by carrying out anti-electrostatic process to the outside surface of base material, can not produce electrostatic when protective membrane and other article are rubbed; Pressure-sensitive adhesive layer is made up of the equal pressure-sensitive adhesive layer block in interval and anti-electrostatic particle, and pressure-sensitive adhesive layer block structurally guarantees that release layer has good peeling force, and anti-electrostatic particle makes release layer also not produce electrostatic when peeling off, and finally realizes permanent electrostatic-proof function.The utility model product is after long-time use, and antistatic backing wearing and tearing also can not occur or comes off, and makes the utility model have permanent antistatic.
