Description
Technical field
The utility model relates to electric adhesive tape field, specifically a kind of antistatic PU one side glue of print grid.
Background technique
With the development of electronics industry, the component type of electronic product is more and more diversified, and volume is also smaller and smaller, especially
The appearance of more cornerites, curved surface, the requirement for the one side glue or double-sided adhesive that are commonly used are also higher and higher in its component.
Since materials such as conventional PET, PI itself are partially hard, cause when being bonded curved surface and cornerite, it is not easy to attach while easily de- over time
From and be bonded when be also easy to produce bubble, and material not scratch resistance itself.Conventional height glues one side glue in slitting, cross cutting processing, removing
Very big electrostatic pressure can be generated Deng during, be easy to produce Electrostatic Absorption and caused glue surface bad order or fitting abnormal, more seriously
The punch through damage that will cause electronic component.In order to make adhesive tape have good attaching and exhaust performance, it will usually use net
Mode that lattice release paper, grid release film and glue surface directly fit forms grid glue surface by the way of intaglio plate coating,
To improve the exhaust performance of product, but the former is formed by that grid easily collapses over time and levelling, the grid glue surface of the latter are thick
Degree and peeling force are limited larger by gravure roll, and controlled range is relatively narrow, and the equally easy levelling of grid, disappearance over time,
It cannot achieve permanent exhaust.
Summary of the invention
The main purpose of the utility model is to provide a kind of antistatic PU one side glues of print grid, to reach exhaust performance
Function good, antistatic effect is good, attaching is had excellent performance.
In order to achieve the object, the utility model provides the following technical solutions.
A kind of antistatic PU one side glue of print grid, which is characterized in that from top to bottom include: scratch resistant layer, first antistatic
Layer, polyurethane PU substrate layer, antistatic glue layer, printing net compartment and release film layer, the release film layer include release layer,
Two antistatic layers, pet layer and third antistatic layer；The release film release layer is bonded with printing net compartment.
Further, for polyurethane PU layer with a thickness of 10-100 μm, color can be transparent, black or any one other face
Color.It is preferred that polyurethane PU layer is with a thickness of 15-50 μm, color is black.
Further, for scratch resistant layer with a thickness of 0.5-3 μm, preferred thickness is 0.8-1.5 μm.
Further, the thickness of the first electrostatic layer, the second electrostatic layer and third electrostatic layer is 0.05-1 μm, and electrostatic face is quiet
Electric value is 105-1010Ω, the first electrostatic layer, the second electrostatic layer and third electrostatic layer preferred thickness are 0.1-0.5 μm, preferably quiet
Electricity value is 106-109Ω。
Further, antistatic glue layer is acrylate pressure sensitive adhesive, with a thickness of 5-50 μm, peeling force 100-3000gf/
In, glue surface static value are 106-1011Ω, antistatic glue thickness degree is preferably 5-30 μm, and glue surface static value is preferably 108-1010
Ω。
Further, printing net compartment is by coating process again through ultraviolet light, in the permanent net that glue surface is formed
Trellis non-sticking lining, coating layer thickness are 0.02-1 μm, and preferred thickness is 0.05-0.5 μm.
Further, the mesh shape of printing net compartment is any one polygon or two kinds and two or more polygons
Combination, preferred grid shape are diamond shape, regular hexagon.
Further, for release film layer with a thickness of 10-100 μm, layer upper surface static value is 106-1011Ω, release film are preferably thick
Degree is 20-70 μm, and layer upper surface static value is preferably 106-109Ω。
The utility model has the beneficial effects that: the permanent antistatic property and scratch resistance being vented and exhaust effect is good, excellent
Performance.
Detailed description of the invention
In order to illustrate more clearly of the technical scheme in the embodiment of the utility model, it is explained below in conjunction with attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the utility model printing net compartment schematic diagram.
Appended drawing reference: 1- scratch resistant layer, the first antistatic layer of 2-, 3- polyurethane PU substrate layer, 4- antistatic glue layer, 5- print
Brush clathrum, 6- release film layer, 61- release layer, the second antistatic layer of 62-, 63-PET layers, 64- third antistatic layer.
Specific embodiment
Following embodiment is only described in further detail the utility model in conjunction with attached drawing, and described embodiment is only
As the utility model preference, instead of all the embodiments, the protection scope of the utility model cannot be used as a limitation.Base
In the embodiments of the present invention, those skilled in the art without making creative work it is obtained it is all its
His embodiment, fall within the protection scope of the utility model.
Embodiment.
It please refers to shown in Fig. 1, Fig. 2, the utility model provides a kind of antistatic PU one side glue of print grid, including scratch resistant
