TW503086B - Mobile phone cover capable of shielding magnetic waves - Google Patents

Abstract

The present invention relates to a mobile phone cover capable of shielding magnetic waves, which comprises: a mobile phone cover body; an antenna; and a transparent plastic sheet. A magnetic-wave-shielding layer is applied on the mobile phone cover body and extended to the antenna part. Such a layer has the effect of shielding magnetic waves without affecting the reception effects of the mobile phone. A. The magnetic-wave-shielding mobile phone cover layer is: (1) a surface layer-a PU resin coating layer, a bottom layer - a composite fiber nonwoven fabric layer or an ordinary fiber nonwoven layer, a stainless steel fiber nonwoven fabric layer mixed with a composite fiber nonwoven fabric; (2) a surface layer - a PU resin coating layer, a bottom layer - a nonwoven fabric layer of a composite fiber or a mixture of an ordinary fiber and a stainless steel fiber. B. The antenna layer is a tubular knitted fabric layer. C. The transparent plastic layer is a layer used on a push key part and is produced by mixing a stainless steel fiber with plastic granules of PVC or PE or nylon or PP or PET in a specific relative ratio, and extruding the mixture through a mold head using an extruder to press out a hot-pressed transparent plastic sheet with magnetic-wave-shielding function. The mobile phone cover body, the antenna and the transparent plastic sheet made of the abovementioned materials can reduce more than 90% of the magnetic wave transmittance so that a human body will not be affected by magnetic waves.
