Description
Technical field
It is more particularly to a kind of to be applied to electronics the present invention relates to a kind of method for the antistatic effect for extending antistatic film
The method of the antistatic effect of the extension antistatic film of packaging material.
Background technology
The material for being most widely used for forming antistatic layer at present is PEDOT:PSS solution, it is that (3,4- stretch second by poly-
Base dioxy thiophene) [Poly (3,4-ethylenedioxythiophene), that is, above-mentioned PEDOT] middle poly- (benzene second of addition
Alkene sulphonic acid ester) [poly (styrenesulfonate), that is, above-mentioned PSS] and be made.However, actual use by
PEDOT:During antistatic layer obtained by PSS solution, it has been found that because PEDOT is easily by ultraviolet light, oxygen and warm in environment
Degraded situation occurs etc. the influence of the factor, causes PEDOT antistatic efficiency to weaken, more allows the usage cycles of antistatic layer to contract
It is short.In order to solve the above problems, presently mainly slow down declining for antistatic efficiency using the gimmick of antistatic layer thickness is increased
Back speed degree, but the method can increase cost, more cause product competitiveness to decline.
US7,087,351 discloses a kind of automatically controlled display, and it includes an at least base material, at least one is arranged on the base material
Automatically controlled image bearing layer (electrically modulated imaging layer), at least a conductive layer and at least one are antistatic
Layer.PEDOT can be used in the antistatic layer:PSS (trade name " Baytron "), and the conductive layer can be divided into leading electric layer and second
Conductive layer, second conductive layer contains tin indium oxide (indium-tin-composite oxide, ITO), zinc oxide or oxidation
The oxides such as cerium.The conductive layer only provides the function of conduction, interactive relation is had no between antistatic layer, also non-confrontational electrostatic layer
Service life any contribution is provided.Just encapsulated after the production of this class display, so antistatic layer is packaged in encapsulating shell.
In under this situation, antistatic layer is completely cut off completely with extraneous, without being influenceed by the aforesaid environmental factor, so will not produce anti-quiet
The problem of electrical efficiency is decayed.
US6,921,576 disclose it is a kind of be used for formed one have preferable hardness, the antistatic film of abrasion resistance it is antistatic
It is coated with constituent.The antistatic coating constituent includes (A) multiple inorganic oxide particles with side chain；(B) one is antistatic
Agent, following constituted group is selected from containing at least one：Macromolecule containing quarternary ammonium salt, the silane coupling agent containing quarternary ammonium salt
And the hydrolytic condensate of silane coupling agent；And (C) has multifunctional (methyl) propylene of at least three (methyl) acryloyl groups
Acid esters.This patent mainly lifts the hardness and abrasion resistance of antistatic film with special modified inorganic oxide particle,
Specific antistatic additive is more utilized, can just allow the anti-static function of antistatic film to be lifted.As shown in the above, the composition of this patent
Thing also needs the ancillary cost time to prepare specific modified inorganic particulate and antistatic additive except that need to use certain material, and after
Continuous when the constituent of this patent is coated on into a plastic basis material, the thickness range being coated with need to be controlled with regard to overall process and follow-up
For, step is excessively complicated and can not save manufacturing cost.In addition, the technology disclosed in the patent do not address it is any can
The possibility that the antistatic coating constituent of extension is used.
From the foregoing, the existing research and development for antistatic film, it is directed to lifting the antistatic behaviour of antistatic film mostly, hard
The property such as degree or abrasion resistance, and do not inquired into regard to how to extend the antistatic effect of antistatic film.Particularly just it is used for electricity
The antistatic film of attached bag package material, because electronic building brick is easily influenceed effective utilization by electrostatic influence or even damaged, institute
With electronic packaging materials in addition to it need to possess transparency and good mechanical properties, it more desirable to antistatic effect can be maintained for a long time.
Therefore, antistatic film is possessed transparency and maintain antistatic effect for a long time, still have processing procedure yet-to-be developed simple again
The method that raw materials for production cost can be reduced, to lift the application field and competitiveness of product.
CN 102476490B disclose the method and transparent antistatic of a kind of antistatic effect for extending antistatic film
Film, it has some improvement and improved to antistatic behaviour and service life, but its antistatic layer surface impedance is 106-107
Left and right, still needs further raising.
The content of the invention
Need further to be improved to solve the antistatic effect of conventional electronic packaging materials, and service life is relative
Shorter the problem of, while taking into account the transparency and manufacturing cost of packaging material, inventor develops one after multi-party experiment
Effective improving countermeasure is planted, method of the invention can make the antistatic layer surface impedance of antistatic film 104-105, make
