Reflecting film and manufacturing method thereof, and use of the reflecting film

Abstract

The invention relates to a reflecting film and a manufacturing method as well as application of the reflecting film. The reflecting film comprises a substrate and a bottom liner surface and is characterized in that the substrate adopts a PET plastic film with high transparency; aluminum films are plated on both sides of the substrate; one surface of the substrate which is plated with the aluminum film is bonded with the bottom liner surface by oiliness pressure sensitive adhesive; a layer of silicone glass resin coating is coated evenly on another surface of the substrate which is plated with the aluminum film. The invention has the advantages that both sides of the substrate are plated with aluminum, thus having a high reflecting rate; if the aluminum film in one surface is scarified, the aluminum film in another surface can still reflect and the reflecting rate can reach more than 85 percent; the oiliness pressure sensitive adhesive has high viscosity and strong bonding force and can be used for more than three years; a reflecting layer can not be dropped off from the bottom liner surface; the surface coating hardness of the reflecting layer is more than 4H and the reflecting layer has strong friction resistance and weather resistance; the reflecting film used in a solar cooker is a new generation product of the solar cooker made by glasses previously, which has light weight, simple bonding and durable use. The reflecting film of the invention can not only be used in the solar cooker, but also be suitable for reflecting in a plurality of fields such as solar energy cooking ranges, vegetable greenhouses and fruit trees.

Description

Technical field: [0001] The invention relates to a reflective film, a manufacturing method thereof and an application of the reflective film. Background technique: [0002] At present, there are many types of reflective films for various purposes. Generally, the reflective films used to collect solar energy include metal films, such as aluminum films, tin films, etc., and some are coated with metal films on one side of a certain substrate, and the other side is pasted The direct metal film is easily damaged, and has light leakage, and the reflective rate is low; the reflective film coated with a metal film on one side of the substrate is a single-sided coating, which also has the problem of light leakage and low reflection. Especially after the coating film is scratched in use, the scratched part has no reflective property, and the base material of this existing reflective film is poorly combined with the backing surface, and it is easy to come off.
