A kind of film adhesive tape with air discharge duct
Technical field
The utility model relates to a kind of film adhesive tape, is meant a kind of film adhesive tape with air discharge duct especially; Belong to the matrix material technical field.
Background technology
The film adhesive tape is widely used in fields such as electronics, communication, electrical equipment, household electrical appliances, building, printing, aviation, automobile making, need bonding, electrical equipment film, high temperature resistantly cover, occasions such as waterproof sealing, absorbing buffering, electromagnetic shielding, anticorrosion fire prevention all widely apply various film adhesive tapes, also make the film adhesive tape develop the multiple product that is suitable for different occasions for this reason.
Existing film adhesive tape generally includes thin film layer, glue-line and foundation base, and glue-line is sold as an integral product attached on the foundation base.The client tears glue-line after buying the film adhesive tape from foundation base, glue-line is attached at then needs film, cover or the enterprising enforcement of object (as electronic component) of waterproof sealing etc. is used.A kind of comparatively common foundation base is a separate-type paper.For convenience of description, the one side that separate-type paper is connected with glue-line, we are referred to as release recto, and another side is referred to as the back side.The one side that glue-line is connected with separate-type paper, we are referred to as the front of glue-line, and another side is referred to as the back side.The back side and film be compound has formed the film adhesive tape that we want.
Now, the front of release recto and glue-line all is the plane.The front of glue-line is attached on the object (as electronic component), is easy to generate bubble during attaching.Because electronic component its surperficial distribute heat of when work, make and air expanded by heating in the bubble destroy the adhesive power of glue-line thus, even influence defective such as electronic component use.
The utility model content
The utility model purpose is to have proposed a kind of film adhesive tape that has air discharge duct in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of film adhesive tape that has air discharge duct, generally include thin film layer, glue-line and foundation base, the front of foundation base is provided with the grid of convex, glue-line is attached to the front of foundation base, and glue-line makes under pressure and has and the corresponding concavity grid of described convex grid on the front of glue-line.
Preferably, the grid of convex adopts 15 order *, 15 orders in unit cell.
Preferably, glue-line 10 kilograms cold pressing and the effect of wheel load under make the front of glue-line have the grid with the corresponding concavity of described convex grid.
Preferably, described foundation base adopts the positive separate-type paper of convex grid that has.
Preferably, basic unit's face also can be designed as some point-like grooves, after adhesive tape and the basic unit's face pressing, produces and the corresponding some point-like projecting points of groove on the adhesive tape, and it is that air is discharged from the slit between each point that adhesive tape and electronic component are fitted.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Compared with prior art, the positive layer of glue-line of the present utility model is provided with the concavity grid, and when the glue-line front was attached to electronic component surperficial, the concavity grid promptly can be used as air discharge duct, avoids occurring bubble.

Embodiment
Below in conjunction with accompanying drawing the utility model is described.
Be depicted as a kind of film adhesive tape that has air discharge duct of the present utility model as accompanying drawing 1,2,3,4, comprise glue-line 2 and foundation base 1, the front of foundation base 1 is provided with the grid 12 of convex, glue-line 2 is attached to the front of foundation base 1, and glue-line 2 makes under pressure and has and described convex grid 12 corresponding concavity grids 11 on the front of glue-line 2.
In the present embodiment, convex grid 12 adopts 15 order *, 15 orders in unit cell, and in like manner, concavity grid 11 also is to adopt 15 order *, 15 orders in unit cell.Convex grid 12 can adopt the style of even setting, also can be irregular latticed, still, usually for easy to process, and adopts the grid of regular shape.
In the present embodiment, glue-line 2 10 kilograms cold pressing and the effect of wheel load under make the front of glue-line 2 have and convex grid 12 corresponding concavity grids 11.
In the present embodiment, foundation base 1 adopts the positive separate-type paper of convex grid that has.
Basic unit's face also can be designed as some point-like grooves, after adhesive tape and the basic unit's face pressing, produces and the corresponding some point-like projecting points of groove on the adhesive tape, and it is that air is discharged from the slit between each point that adhesive tape and electronic component are fitted.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
The positive layer of glue-line of the present utility model is provided with the concavity grid, when the glue-line front attaches to electronic component surperficial, the concavity grid promptly can be used as air discharge duct, and air distributed by air discharge duct when adhesive tape was attached to electronical elements surface, avoids bubble occurring in glue-line attaching process.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
