preparation example Construction

[0028] The preparation method of the silver-plated composite reflection film provided by the invention comprises the steps:

[0029] (1) Prepare reflective polyester film layer;

[0030] (2) Place 99.99% silver in the target of the sputtering chamber, use Ar as the sputtering gas, and the vacuum degree is 10-1.0×10 -1 Pa, the working temperature is 850-1000°C, the film-forming speed is 0.01-5mm / min, a silver-plated layer is formed on the reflective polyester film layer, and annealing is performed at room temperature under nitrogen to accelerate the crystallization of the silver-plated layer;

[0031] (3) Using the dry coating method, using the pre-prepared protective layer film, through a 90°C heating channel and hot pressing, the protective layer film is composited on the silver-plated layer prepared in step (2), and wound up.

[0032] Prepare the silver-plated composite reflective film according to the above-mentioned method, and its various performance test methods are as ...

Embodiment 1

[0035] The silver-plated composite reflective film was prepared according to the above method, the thickness of the reflective polyester film layer was 50 μm, the thickness of the silver-plated layer was 1.5 μm, and the protective layer was a polyethylene film with a thickness of 20 μm. The relevant properties of the obtained composite reflective film are shown in Table 1.

Embodiment 2

[0037] The silver-plated composite reflective film was prepared according to the above method. The thickness of the reflective polyester film layer was 75 μm, the thickness of the silver-plated layer was 1.2 μm, and the protective layer was a polypropylene film with a thickness of 15 μm. The relevant properties of the obtained composite reflective film are shown in Table 1.

Abstract

The invention relates to the technical field of reflecting films, in particular to a silver-plated reflecting film and a preparation method thereof. To overcome the defect that the reflectivity of an existing optical reflecting film still needs to be increased, the silver-plated reflecting film is provided. The silver-plated reflecting film comprises a reflecting polyester film layer, a silver-plated layer and a protecting layer, wherein the reflecting polyester film layer comprises 5-25% of nano-modification inorganic filler. The silver-plated reflecting film is high in reflectivity, and the preparation method is simple in process and easy to operate.

Description

technical field [0001] The invention relates to the technical field of reflective films, in particular to a silver-plated reflective film and a preparation method thereof. Background technique [0002] The liquid crystal backlight system is mainly composed of light source, light guide plate, various optical films and structural parts. Its development tends to be diversified and portable in size, and has high requirements for luminous brightness. At present, the types of backlight mainly include electroluminescent sheet (EL), cold cathode fluorescent tube (CCFL), light-emitting diode (LED), etc., which are divided into side-light type and bottom-light type according to their positions. With the development of LCD modules, high-brightness and thin side-lit CCFL backlights have become mainstream, but due to high power consumption, they cannot meet the energy-saving requirements of portable information products. Therefore, it is necessary to increase the backlight without increa...
