Abstract
A kind of shading reflection tape, comprises the first ink layer being superimposed on white base membrane layer one side successively, the second ink layer, adhesive layer, release film layer, and is superimposed on the coating of titanium dioxide of other one side of white base membrane layer successively, adhesive layer, release film layer.Compared with prior art, the utility model has the advantage of: by the superimposion of double-deck ink layer, as the pin hole produced when making the first layer ink be that PET basement membrane contacts, the evacuation hole of size obtains shutoff, and light transmission obtains solution fundamentally.In addition, white basement membrane coated on one side has coating of titanium dioxide, and its high whiteness and luminance brightness make light reflective greatly strengthen.Further, the restriction of overall each layer thickness makes die cuttability greatly strengthen.
Description
Technical field
The utility model belongs to adhesive tape protective membrane technical field, particularly relates to a kind of shading reflection tape.
Background technology
LCD liquid-crystal display and backlight module are fixed requirement and are provided a kind of shading reflecting double-sided tape.The shortcoming that existing shading reflecting double-sided tape all there is opacifying property and reflective is poor, die cuttability is bad, especially when darkroom LED lamplight is irradiated, have the light leakage phenomenon of pin mark size, this has had a strong impact on its shielding.In addition, plane of reflection light reflective difference also can have a strong impact on the fixing performance of LCD liquid-crystal display and backlight module.It is unreasonable all to there is structure design in existing shading reflection tape, the shortcoming of shaded effect difference.
Utility model content
The purpose of this utility model in order to solve existing opacifying property and reflective difference and design.
Solution of the present utility model is: a kind of shading reflection tape, and by white base membrane layer, white base membrane layer one side stackedly to be added by following: the first ink layer, the second ink layer, adhesive layer, release film layer; The other one side of white basement membrane stackedly to be added by following: coating of titanium dioxide, adhesive layer, release film layer.Aforementioned white basement membrane thickness is 15-25 μm, the PET that material is; Aforementioned first ink film thickness is 3-5 μm; The thickness of aforementioned second ink layer is 2-3 μm; The thickness of aforesaid titanium dioxide coating is 2-5 μm; The adhesive layer being arranged at white basement membrane both sides is all acrylic acid adhesive, and thickness is 10-30 μm; The release film layer thickness bonded with white basement membrane both sides adhesive layer is 15-50 μm, and material is PET.
Compared with prior art, the utility model has the advantage of: by the superimposion of double-deck ink layer, as the pin hole produced when making the first layer ink be that PET basement membrane contacts, the evacuation hole of size obtains shutoff, and light transmission obtains solution fundamentally.In addition, white basement membrane coated on one side has coating of titanium dioxide, and its high whiteness and luminance brightness make light reflective greatly strengthen.Further, the restriction of overall each layer thickness makes die cuttability greatly strengthen.
Accompanying drawing explanation
Fig. 1 is embodiment 1-3 structural representation.
