Abstract
The utility model discloses a two -sidedly prevent high temperature resistant polyimide sticky tape of static, including the polyimide substrate, a top -coat of polyimide substrate is equipped with a conducting coating, and another top -coat is equipped with the 2nd conducting coating, and the 2nd conducting coating's a top -coat is equipped with the siloxane under coat, and a top -coat of siloxane under coat is equipped with the siloxane adhesive layer, and the thickness size of polyimide substrate is 25 -50um, and a conducting coating and the 2nd conducting coating's thickness size is 0.2 -0.8um. Scribbling respectively through the two sides at the polyimide substrate and establishing a conducting coating and the 2nd conducting coating who has anti -static function, make it have a two -sided anti -static function, make antistatic properties stronger, the sticky tape is high temperature resistant to reach 280 DEG C, make its have stronger high temperature resistance can, and high temperature resistant ageing back, the sticky tape does not have the cull, does not have and sticks up, has the shrink, has avoided the problems by the production of ion type additive in addition.
Description
Technical field
This utility model relates to tape applications field, particularly to a kind of two-sided antistatic high temperature resistant Kapton Tape。
Background technology
Electronic product is made up of electronic devices and components, and electronic devices and components are when destruction by electrostatic field, and the execution of generation is all different。Progressively research along with the development of electronic technology and integrated circuit, the degree magnified and needed that produces of electronic product is gradually increased, the electrostatic hazard of electronic product also becomes more and more obvious, from the pretreatment of electronic devices and components, until the packaging of electronic devices and components completes, all can there is the harm that electrostatic produces。The integrated development of electronic product, the application of large-scale integrated circuit, electronic devices and components progressively tend to gadget, micro element so that electronic component is more sensitive to the reaction of electrostatic, is more difficult to overcome。Wherein printed circuit board (PCB) (PCB) needs high temperature masking tape in crossing wave-soldering or reflow soldering process; its golden finger and some components and parts are protected; have higher temperature tolerance so that a kind of, do not rise in the course of processing of high temperature is protected rouse, warp, without cull, without the adhesive tape of obvious contraction, electrostatic-proof function。
More or less all there are some problems in more existing antistatic adhesive tapes, antistatic adhesive tape such as ion-type, in a period of time after having produced, anti-static effect is more satisfactory, but time longer between when left, there will be the situation that anti-static effect is inconspicuous or disappears, high temperature is it is also possible that the anti-static effect of adhesive tape disappears；Some antistatic agent temperature tolerances are good not, when crossing wave-soldering, it may appear that decompose and cause playing the function of antistatic；Or some ion-type additive, its electrostatic conductive performance relies primarily on humidity in environment, in hot environment, will be unable to the anti-static electrification brought into normal play。The product also having introduces ion-type additive to glue-line, and because these ion-type additives directly can contact with PI face, and existence is migrated by film surface and transferred to the risk on PI face, pollutes PI face。
Utility model content
For solving Problems existing in above-mentioned background technology, the purpose of this utility model is in that to provide a kind of two-sided antistatic high temperature resistant Kapton Tape, and to reach to make it have two-sided antistatic property, antistatic behaviour is higher, and the purpose that resistance to elevated temperatures is more preferably。
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of two-sided antistatic high temperature resistant Kapton Tape, including polyimide base material, the one side of described polyimide base material is coated with the first conductive coating, another side is coated with the second conductive coating, the one side of described second conductive coating is coated with siloxanes priming coat, the one side of described siloxanes priming coat is coated with siloxane glue adhesion coating, and the gauge of described polyimide base material is 25-50um, and the gauge of described first conductive coating and the second conductive coating is 0.2-0.8um。
Preferably, the gauge of described siloxane glue adhesion coating is 32-38um。
Pass through technique scheme, the two-sided antistatic high temperature resistant Kapton Tape that this utility model provides, by being coated with first conductive coating with antistatic property and the second conductive coating respectively on the two sides of polyimide base material, make it have two-sided antistatic property, make antistatic behaviour higher, adhesive tape is high temperature resistant reaches 280 DEG C, make it have higher resistance to elevated temperatures, and after heat resistant, adhesive tape without cull, without warping, ungauged regions, and avoid the problems produced by ion-type additive。
