Problems solved by technology

Among them, it is difficult to control the foaming density of the foamed optical grade PET film, which will affect the reflectivity and the yield rate is poor
However, these two types of optical-grade PET films have problems such as expensive manufacturing machines and production costs, difficult control of thickness, and deterioration and yellowing due to ultraviolet radiation.

Embodiment Construction

[0025] The reflective paint composition of the present invention includes a plurality of reflective particles and at least two resins. The reflective particles account for 35% to 75% by weight of the reflective paint composition, preferably 45% to 50%. The plurality of reflective particles include titanium dioxide, barium sulfate, silicon dioxide or a mixture thereof, and the particle size is between 0.3 μm and 10 μm. Specifically, in a preferred embodiment, the reflective particles are selected from titanium dioxide, however, in different embodiments, the reflective particles can be selected from barium sulfate, silicon dioxide or other reflective particles.

[0026] At least two resins account for 65% to 25% by weight of the reflective paint composition, preferably 55% to 50%, and one of them is a modified epoxy acrylic resin. A plurality of reflective microparticles and at least two kinds of resin together account for less than or equal to 100% by weight of the reflective ...

Abstract

The invention provides a reflecting coating component and a reflector plate using the same. The reflecting coating component comprises a plurality of reflecting particles and at least two types of resins. The weight percent of the plurality of reflecting particles is within a range of 35-75%. The weight percent of the at least two types of resins is within a range of 65-25% and one type of resin is denatured epoxy acryl resin. The reflector plate provided by the invention comprises a base plate and a reflecting layer arranged on the base plate. The reflecting layer is composed of the reflecting coating component.

Description

technical field [0001] The invention relates to a reflective paint composition and a reflective sheet using the reflective paint composition, which can be used in display devices. Background technique [0002] In recent years, liquid crystal displays (Liquid Crystal Displays) have become the mainstream of various display devices. For example, household televisions, personal computers, laptop computers, monitors, mobile phones, and digital cameras are all products that use liquid crystal display devices in large quantities. Wherein, the backlight module (Backlight Module) applied to the liquid crystal display device is used to supply the liquid crystal with sufficient brightness and evenly distributed light source, so that the liquid crystal display device can display images normally. The reflector used in the backlight module directly affects the performance and assembly cost of the backlight module. [0003] Figure 1A and 1B They are direct type and edge type backlight ...
