Abstract

The invention discloses an anti-wrinkle silver reflecting film and a processing technology thereof. The processing technology comprises the steps that heat conduction powder A and heat conduction powder B are mixed, a solvent is poured into the mixture to prepare heat conduction powder slurry, then an anti-aging oxidation auxiliary, polyurethane resin and the solvent are stirred and mixed, the heat conduction powder slurry is added, and a heat conduction coating is prepared; the upper surface and the lower surface of a PET film are coated with the heat conduction coating at the coating speed of 1.3-1.5 g / m<2> and the coating speed of 0.6-0.9 g / m<2> correspondingly, and a heat conduction pre-coating film is prepared; and the heat conduction pre-coating film and the silver plating film are attached together through polyester-polyurethane glue, and an anti-wrinkle silver reflecting film is obtained. According to the anti-wrinkle silver reflecting film and the processing technology thereof, the prepared silver reflecting film has good anti-wrinkle performance, aging and layering phenomena do not occur even if the silver reflecting film works in a high-temperature environment for a longtime, the adhesion between film layers is good, and the practicability is high.

Description

technical field [0001] The invention relates to the field of functional films, in particular to an anti-wrinkle silver reflective film and its processing technology. Background technique [0002] The LCD itself does not have a display function, and the LCD backlight module must be used to realize its display function. The reflective film is a part of the LCD backlight module. It is located at the bottom of the LCD backlight module. There is a light guide plate above the reflective film. The function of the reflective film is to reflect back the light leaked through the light guide plate efficiently and without loss. , so that the light returns to the panel side, thereby reducing light loss and increasing brightness. Silver reflective film is pure silver or silver alloy thin film material with silver as the absolute main component. It has high reflectivity in visible light region and infrared light region, and is widely used in liquid crystal display backlight modules and li...
