Problems solved by technology

However, the reflective film with microbubbles is full of voids, which leads to a decrease in the density of the reflective film and a decrease in the stiffness of the film. Specifically, when it is used, the film will bend, especially in TVs, liquid crystal displays, advertisements, etc. It is more serious in areas such as light boxes that require the diaphragm to be placed vertically

Embodiment Construction

[0014] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0015] Reference figure 1 , A high-stiffness composite reflective film, comprising a reflective film base layer 1, said reflective film base layer 1 has microbubbles 2 inside, and an adhesive layer 3 is provided on the back of said reflective film base layer 1, said adhesive layer 3 is pasted with a reinforcement layer 4. The adhesive layer 3 can be an acrylate adhesive, a polyurethane adhesive, an epoxy adhesive, or a phenolic resin adhesive.

[0016] In this embodiment, the material of the reflective film base layer 1 is PET; during molding, the PET of the reflective film base layer is mixed with nucleating particles that are incompatible with PET, and the PET masterbatch mixed with the nucleating particles is melted and plasticized After casting and biaxial stretching, microbubbles are formed in the PET film with nucleated particles as the center. ...

Abstract

A high-stiffness composite reflecting film comprises a reflecting film substrate, wherein microbubbles are formed in the reflecting film substrate, an adhesive layer is arranged on the back side of the reflecting film substrate, and a reinforcing layer adheres to the adhesive layer. The reflecting film is provided with multiple layers, is good in stiffness, and can not be bent easily.

Description

(1) Technical field [0001] The invention relates to a reflective film. (2) Background technology [0002] Liquid crystal display (LCD, LiquidCrystalDisplay) has become the most common display technology today. Because LCD has the advantages of environmental protection, low energy consumption, low radiation, and soft screen, LCD will be the mainstream display technology in the next few decades. LCD is a non-luminous display device, which requires the use of a backlight source to achieve the display function, so the performance of the backlight source will directly affect the display 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 three main types of light sources: EL, CCFL, and LED, which can be divided into two types: side-light type and direct-light type according to different light source distribution positions. With the continuous development of LCD modules in t...
