Abstract

A disclosed anti-fingerprint adhesive tape for the wireless charger comprises a black ink layer, a base material layer and an adhesive layer, the black ink layer and the adhesive layer are located onthe upper surface and the lower surface of the base material layer respectively, and a release layer is arranged on the side, opposite to the base material layer, of the adhesive layer. the black inklayer is obtained by drying black ink, and the black ink is prepared from the following components in parts by weight: 60-80 parts of waterborne polyurethane, 1-5 parts of carbon black, 1-5 parts of 1,1',1''-methylidynetris(4-isocyanatobenzene), 1-1.5 parts of sodium silicate, 1-1.5 parts of carboxymethyl cellulose, 0.1-0.3 part of sodium tripolyphosphate, 1-5 parts of polyethyleneimine, 0.5-2 part of octadecyl dimethyl benzyl ammonium chloride, 2-4 parts of a light absorbing agent, 0.5-1.5 part of a coupling agent, 0.5-1 part of chitosan and 15-25 part of deionized water. The anti-fingerprintadhesive tape for the wireless charger has anti-fingerprint performance, fingerprint traces cannot be left after the anti-fingerprint adhesive tape is used for multiple times in various environments,and corrosion of fingerprint sweat stains to the adhesive tape 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...
