Abstract
The utility model discloses the ultra-thin one-faced tapes of a kind of black; it is made up of ink protective layer, black ink layer, pressure-sensitive adhesive layer and release film; black ink layer is provided with above described ink protective layer; be provided with pressure-sensitive adhesive layer above described black ink layer, above described pressure-sensitive adhesive layer, be provided with release film.The ultra-thin one-faced tapes of black of the present utility model not only meets the requirement of peeling force, also guarantee its thickness 12 μm (not comprising release film thickness) below, can reach 10 μm thick, and transmittance is below 0.2%, has and well hides and shielding effect.
Description
Technical field
The utility model relates to a kind of one-faced tapes, is specifically related to the ultra-thin one-faced tapes of a kind of black.
Background technology
Along with the rise of the electronicss such as smart mobile phone, the particularly progress of NFC technique, requires more and more higher to the electromagnetism interference of electronic devices and components.Electromagnetic shielding material, absorbing material arises at the historic moment.Due to these shielding materials, absorbing material outward appearance defect to some extent, and ultra-thin adhesive tape can just solve these problem of appearance.When using ultra-thin adhesive tape, being pasted onto on dirt settling by adhesive layer, thus substrate layer fixedly can being pasted onto on attached crop, the high shading black coating on substrate layer plays to dirt settling effects such as hiding apparent flaws.
The usual total thickness of existing black one-faced tapes is not more than 15 μm (comprising release film thickness); structure is the black pet sheet face painting black ink of 3 μm; then layer protective layer is coated with again on black ink surface; total thickness of adding up is at 12 μm, and after pressure-sensitive adhesive coating, total thickness is more than 15 μm.In these PET one side glue, or material is too thick, have impact on the performance of absorbing material and shielding material.Material opacifying power is inadequate, can not cover the apparent flaws of absorbing material and shielding material completely.
Prior art typically uses transparent PET film as base material, painting black ink on base material, then coat protective layer again on ink, this technology cannot obtain meet peeling force require while black one-faced tapes thickness also 12 μm (not comprising release film thickness) below, the ultra-thin one-faced tapes of black of the present utility model overcomes this and falls into scarce, it not only meets the requirement of peeling force, also guarantee thickness 12 μm (not comprising release film thickness) below, can reach 10 μm thick (not comprising release film thickness), and transmittance is below 0.2%, have and well hide and shielding effect.
Utility model content
