Problems solved by technology

This method of film production increases the links of the process and increases the cost of film production
Moreover, the coating solution needs to discharge a large amount of organic solvents during the thermal curing process, which will cause certain harm to the environment and employees, which does not meet environmental protection requirements and is not conducive to the healthy development of the industry.

Abstract

A high-performance reflective film comprises a reflective core layer which is composed of polyethylene glycol terephthalate, titanium dioxide particles, polyethylene glycol, poly4-methyl-1-pentene and a benzotriazole ultraviolet absorbent. The reflective film also comprises a diffusion layer which covers the upper surface of the reflective core layer. The diffusion layer is composed of polymethyl methacrylate, MBS resin, polymethyl methacrylate particles, a benzotriazole ultraviolet absorbent and an antistatic agent. The reflective film also comprises an anti-bonding layer which covers the lower surface of the reflective core layer and is composed of polyethylene glycol terephthalate, silicon dioxide particles and an antistatic agent. A preparation method of the reflective film comprises the following steps: A, a diffusion master batch is prepared; B, a reflective master batch is prepared; C, an anti-bonding master batch is prepared; and D, after coextru-lamination, longitudinal stretching is firstly conducted, and transverse stretching is then carried out. A diffusion layer is arranged on one side of the reflective core layer. The diffusion layer has photodiffusion performance, antistatic performance and a function of increasing stiffness and flex-resistance of the reflective film.

Description

(1) Technical field [0001] The invention relates to a reflection film and a preparation method of the reflection film. (2) Background technology [0002] A liquid crystal display (LCD, Liquid Crystal Display) has become the most common display technology today. Because LCD has the advantages of environmental protection, low energy consumption, low radiation, soft picture, etc., LCD will be the mainstream display technology in the next few decades. The LCD is a non-luminous display device, which requires the backlight to achieve the display function, so the performance of the backlight will directly affect the image quality of the LCD. [0003] The main components of the backlight system include: light source, light guide plate, and various optical films. At present, there are mainly three types of light sources: EL, CCFL and LED, which can be divided into side-light type and direct-light type according to the different distribution positions of the light source. With the ...
