Abstract

The invention discloses an anti-fingerprint adhesive tape for a wireless charger, which comprises a black ink layer, a base material layer and an adhesive layer, and the black ink layer and the adhesive layer are located on the upper surface and the lower surface of the base material layer respectively On the surface, the side of the adhesive layer opposite to the base layer is provided with a release layer; the black ink layer is obtained by drying black ink, and the black ink is composed of the following components by weight: water-based polyurethane 60~ 80 parts, 1~5 parts of carbon black, 1~5 parts of 1,1',1"-methine tris (4-isocyanate) benzene, 1~1.5 parts of sodium silicate, 1~ of carboxymethyl cellulose 1.5 parts, 0.1~0.3 parts of sodium tripolyphosphate, 1~5 parts of polyethyleneimine, 0.5~2 parts of octadecyl dimethyl benzyl ammonium chloride, 2~4 parts of light absorbing agent, 0.5~ 1.5 parts, 0.5 to 1 part of chitosan, 15 to 25 parts of deionized water. The anti-fingerprint adhesive tape used for wireless chargers of the present invention has anti-fingerprint performance, and will not leave fingerprints after repeated use in various environments. Corrosion of the tape caused by fingerprint sweat stains can be avoided.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to an anti-fingerprint adhesive tape used for a wireless charger. Background technique [0002] Wireless charging technology, also known as inductive charging and non-contact charging, is a new charging technology derived from wireless power transmission technology. Wireless charging technology has developed rapidly in recent years, but it has also encountered many technical difficulties, such as improving charging efficiency, reducing costs, and the effective charging distance is too short. In order to obtain higher charging efficiency and reduce or eliminate the influence of the electromagnetic field on the mobile phone during charging, it is necessary to use an electromagnetic shielding film for shielding. The function of the electromagnetic shielding film is to isolate the influence of the electromagnetic field on the mobile phone, and prevent materials such as metals fr...
