Abstract
The utility model discloses a kind of moisture-proof conducting foam adhesive tapes, sequentially include: pet layer, foamed cotton layer, the first drying layer, aluminium foil layer, the second drying layer, conductive adhesive layer, form the conducting foam adhesive tape after above each layer is compound；The foamed cotton layer has closed-cell foam structure；First drying layer, the second drying layer construction are identical, are constituted by after active carbon powder and lime powder compacting through asbestos paper peplos package, the asbestos paper peplos is equipped with air-tightness through-hole.Moisture-proof conducting foam adhesive tape provided by the utility model can play preferable moisture-proof function, guarantee that it is used for the electrostatic shield effect inside electronic display unit when being in wet environment operation for electronic display unit.
Description
Technical field
The utility model relates to the moisture-proof conductions of the one kind used in electronics screen display equipment technical field more particularly to equipment
Foam tape.
Background technique
Always electronic product is caused inner body problem frequently to occur by wet gas, the suction of electronic component, wiring board
Cause the decline of component performance, circuit structure impaired after tide, directly affects product quality.
Conductive tape is used to be pasted onto the outer edge of each display panel in electronic display unit, to realize the effect of electrostatic screen
Fruit.However in certain humid areas, humid air often enters in electronic display unit, the problem after causing above-mentioned dampness.It is right
For conductive tape, the humidity resistance of conventional conductive adhesive tape has been unable to satisfy existing technical need, so that wet gas is past
Damage is in turn resulted in toward panel itself is entered from the most weak panel sides of sealing effect.Therefore, it is badly in need of grinding as early as possible in the art
Produce the conductive tape for meeting moisture-proof demand.
Utility model content
The purpose of this utility model is to provide a kind of moisture-proof conducting foam adhesive tapes, are in tide for electronic display unit
When wet environment is run, preferable moisture-proof function is played, guarantees that it is used for the effect of electrostatic screen.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of moisture-proof conducting foam adhesive tape sequentially includes: pet layer, foamed cotton layer, the first drying layer, aluminium foil layer, second
Drying layer, conductive adhesive layer form the conducting foam adhesive tape after above each layer is compound；
The foamed cotton layer has closed-cell foam structure；First drying layer, the second drying layer construction are identical, by activity
It wraps up and constituting through asbestos paper peplos after carbon powder and lime powder compacting, the asbestos paper peplos is equipped with air-tightness through-hole.
In an optional embodiment: the foamed cotton layer with closed-cell foam structure is closed pore EVA foam.
In an optional embodiment: the average grain diameter of the active carbon powder and lime powder is logical greater than the air-tightness
The aperture in hole.
In an optional embodiment: the surface recombination on the conductive adhesive layer far from the second drying layer has release paper.
Compared to the prior art, the utility model in use, when the gas of wet environment is through electronic equipment casing
On heat release hole enter device inside after, the foamed cotton layer with closed-cell foam structure plays the work of first of protection first
With, cannot perforative closed pore construction so that steam is difficult to enter in the region being stuck from pet layer；And in aluminium foil layer
Two sides are compounded with the first drying layer and the second drying layer respectively, so that aluminium foil just has the case where certain moisture protection at itself
Under, further enhance the moisture protection of conducting foam glue.Specifically, the first drying layer, the second drying layer use asbestos
Active carbon powder and lime powder after the package compacting of paper peplos, both the above powder have extraordinary water absorbing properties, and
Asbestos paper peplos is equipped with air-tightness through-hole, and steam is enabled actively to enter the first drying layer, the by the air-tightness through-hole
It is absorbed in two drying layers by the powder in it, thus the moisture protection ability to aluminium foil layer can be greatly promoted.
Detailed description of the invention
Fig. 1 shows the structural schematic diagram of each layer of the utility model embodiment.
Specific embodiment
Fig. 1 is please referred to, it sequentially includes: PET that the utility model embodiment, which discloses a kind of moisture-proof conducting foam adhesive tape,
Layer 1, foamed cotton layer 2, the first drying layer 3, aluminium foil layer 4, the second drying layer 5, conductive adhesive layer 6, after above each layer is compound described in formation
Conducting foam adhesive tape.
The foamed cotton layer 2 has closed-cell foam structure.First drying layer 3, the second drying layer 5 construct it is identical, by
It wraps up and constituting through asbestos paper peplos 7 after active carbon powder and lime powder compacting, the asbestos paper peplos is equipped with air-tightness
Through-hole.
In use, when the gas of wet environment is after the heat release hole on electronic equipment casing enters device inside,
The foamed cotton layer 1 for having the function of closed-cell foam structure plays first of protection first, cannot perforative closed pore construction, make
Steam is obtained to be difficult to enter in the region being stuck from pet layer 1；And it is compounded with the first drying layer 3 respectively in the two sides of aluminium foil layer 4
With the second drying layer 5 so that aluminium foil in the case where itself just has certain moisture protection, further enhances conductive bubble
The moisture protection of celloidin.Specifically, after the first drying layer 3, the second drying layer 5 are using the package compacting of asbestos paper peplos 7
Active carbon powder and lime powder, both the above powder has extraordinary water absorbing properties, and asbestos paper peplos 7 is equipped with airtight
Property through-hole, enable steam actively to enter the first drying layer 3 by the air-tightness through-hole, in the second drying layer 5 by it
Powder absorbs, thus can greatly promote the moisture protection ability to aluminium foil layer 4.
Specifically, the foamed cotton layer 2 with closed-cell foam structure is closed pore EVA foam in the present embodiment.Preferably,
The average grain diameter of the active carbon powder and lime powder is greater than the aperture of the air-tightness through-hole, is not compacted with preventing from not existing
Powder leak.Further, the surface recombination on the conductive adhesive layer 6 far from the second drying layer has release paper 8, thus
Conducting foam adhesive tape is set to keep structural intergrity before stickup.
The above is only the preferred embodiment of the present invention, is not intended to limit its scope of the patents, all to utilize this
Equivalent structure transformation made by utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain is also included in the patent protection scope of the utility model.
