Abstract
The purpose of this utility model is to provide a kind of, and the grid with two-stage groove structure is vented double faced adhesive tape.The film surface of the double-sided adhesive has the first order and second level groove structure.Two-stage groove structure is staggered, both can to avoid because exhaust passage it is larger, lead to the biggish loss of glue-line peeling force, and can be smaller to avoid exhaust passage, the bad problem of exhaust effect.Make glue-line that there is preferable venting quality and higher peeling force.
Description
Technical field
The utility model relates to a kind of grids to be vented double faced adhesive tape, especially with regard to a kind of net with two-stage groove structure
Grillages gas double faced adhesive tape.
Background technique
Pressure sensitive adhesive tape is coated on quick moulding on substrate (PET, PC, PI etc.), has the adhesive tape of sensibility to pressure.Pressure
Sensitive tape no base material adhesive tape and has base material adhesive tape according to whether using substrate that can be divided into；According to purposes can be divided into gummed tape, absolutely
Edge adhesive tape, non-flammable adhesive tape, exhaust adhesive tape etc..
Grid is vented adhesive tape because of its venting quality, is widely used in the graphite attaching process being die cut in industry.Grid double-face glue
Venting quality it is related to the spatial volume of grid, spatial volume is bigger, and exhaust passage is more smooth, and venting quality is better.But grid is empty
Between volume increase the contact area between glue-line and affixed object can be made to reduce, peeling force declines, or even can be with affixed object skin lamination.
Summary of the invention
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of, the grid exhaust with two-stage groove structure is double
Face adhesive tape is guaranteeing preferable venting quality peeling force also with higher simultaneously.
To achieve the above object, the utility model adopts the following technical solution.
A kind of grid with two-stage groove structure is vented double faced adhesive tape, including double faced adhesive tape substrate, the first pressure-sensitive adhesive layer,
Second pressure-sensitive adhesive layer, the first release film and the second release film, at least one in first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer
Layer pressure sensitive adhesive surface has first order groove structure and second level groove structure.
As the preferred embodiment of the technical program, the double faced adhesive tape substrate with a thickness of 1.5 ~ 100 microns.
As the preferred embodiment of the technical program, first pressure-sensitive adhesive layer is acrylic pressure sensitive adhesive, thickness 1.5 ~ 50
Micron.
As the preferred embodiment of the technical program, second pressure-sensitive adhesive layer is acrylic pressure sensitive adhesive, thickness 1.5 ~ 50
Micron.
As the preferred embodiment of the technical program, 5 ~ 100 millimeters of the groove spacing of the first order groove structure, groove is wide
50 ~ 800 microns, 0.3 ~ 15 micron of depth of groove of degree.
As the preferred embodiment of the technical program, 0.8 ~ 8 millimeter of the groove spacing of the second level groove structure, groove is wide
5 ~ 200 microns, 0.1-2 microns of depth of groove of degree.
A kind of grid with two-stage groove structure provided by the utility model is vented double faced adhesive tape, in the net of double faced adhesive tape
Make its surface that there is the first order and second level groove structure by specially treated on lattice deflation area, first order groove structure, which is formed, to be cut
The larger exhaust passage of area, the trunk as exhaust network guarantee that glue-line has good exhaust effect；Second level groove structure is made
For the branch line of evacuation network, the covering to entire glue surface is improved, improves exhaust efficiency, while the row that second level groove structure is constituted
Gas channel cross-sectional area is smaller, and smaller, the whole exhaust glue surface peeling force with higher of guarantee is influenced on the peeling force of glue surface.Two-stage
Groove structure is staggered, and forms grade branching rod structure evacuation network, and glue-line is made to have preferable venting quality and higher removing
Power.
