1. A method for manufacturing a silver-plated reflecting film, wherein the manufacturing method is consisting of following steps:
manufacturing a reflecting polyester film layer;
coating a silver-plated layer directly on one surface of the reflecting polyester film layer by a vacuum sputtering silver plating method; and
applying a protection layer film on the silver-plated layer and obtaining the silver-plated reflecting film,
wherein the vacuum sputtering silver plating method comprises:
putting 99.99% silver in a target of a sputtering chamber, with Ar as a sputtering gas, a vacuum level of 10-1.0×10−1 Pa, a working temperature of 850° C. to 1000° C., and a film forming speed of 0.01 mm/min to 5 mm/min; and
forming the silver-plated layer on the reflecting polyester film layer;
wherein the protection layer is a polycarbonate film, a polyethylene film, or a polypropylene film, the protection layer film is applied on the silver-plated layer by a dry-type film covering method,
the dry-type film covering method comprises following steps:
firstly the protection layer film passing through a heated channel of 90° C.; and
then pressing the protection layer film onto the silver-plated layer.
