Embodiment 1

[0038] Put the 23u PET coil in the unwinding chamber, replace the winding chamber with a new core, clean the chamber, replace the protective plate, and wait for the vacuum to -6 Mbar started production; under the protection of argon, the gas flow rate is 400sccm~500sccm, the chamber uses NiCr target material, medium frequency power (MF power) discharge, so that NiCr is sputtered on the PET surface, so that the thickness of the NiCr layer is 10nm; then the chamber The chamber uses a Cu alloy target. Under the protection of argon gas, the gas flow rate is 400-500 sccm, and the MF power discharges to sputter a 10nm CuSn layer on the surface of the NiCr layer. Finally, the chamber is replaced with a NiCr target material. Under the protection of argon gas, The gas flow rate is 400-500 sccm, and the MF power is discharged, so that the thickness of the NiCr layer is 17 nm, and a flexible film is obtained.

[0039] The performance of the flexible film was detected according to the ASTM...

Abstract

The invention provides a flexible film. The flexible film comprises a flexible base material, a first optical film compounded on the surface of the base material, a second optical film compounded on the surface of the first optical film, and a third optical film compounded on the surface of the second optical film, wherein the first optical film is a NiCr film; the second optical film is a copper alloy film; the third optical film is a NiCr film; the ratio of the thickness of the third optical film to the thickness of the first optical film ranges from 1.2 to 2. In the flexible film provided by the application, the first optical film and the second optical film are used as a medium layers, and are capable of modifying the visible light transmittance of a copper alloy layer; moreover, the thicknesses of the optical films are well matched by limiting the thickness ratio of the optical films, thus favourably ensuring that the flexible film has a high visible light transmittance and a low infrared light transmittance.

Description

technical field [0001] The invention relates to the technical field of film coating, in particular to a flexible film. Background technique [0002] Glass window film is a multi-functional polyester composite film material, which can improve the performance and strength of glass when pasted on the glass surface. According to different application fields, glass window film can be divided into: architectural glass window film, automobile glass window film and safety glass window film. Among them, the automotive glass window film pasted on the inner and outer surfaces of the automotive glass has the functions of energy saving and heat insulation, UV protection, safety and anti-theft; at the same time, it has high requirements on the visible light transmittance and visible light reflectance of the window film. [0003] Pure silver is a silvery-white metal with good ductility, and its electrical conductivity and thermal conductivity are the highest among all metals. Silver exis...
