Problems solved by technology

However, the technical scheme of the invention still adopts the layered structure of A+B. Although the problems of deformation and deterioration of the reflective film after long-term use are solved, the stacked layered structure is still maintained during processing and production. Due to the complex process, it is difficult to produce efficiently and continuously

Embodiment 1

[0022] A PC, PBT reflective material, according to the ratio of 38% polycarbonate, 58% rutile titanium dioxide (average particle size of 0.1 micron), 2% dispersant (such as paraffin), 1.5% compatibilizer (such as polyethylene glycol 400) and 0.5% hindered phenolic antioxidant (such as antioxidant 2,6-di-tert-butyl-4-methylphenol) were added to a high-speed mixer and stirred evenly for flow Extend or extrude to obtain the product, and perform performance testing on it.

Embodiment 2

[0024] A PC, PBT reflective material, according to the ratio of 45% polycarbonate, 54% rutile titanium dioxide (average particle size of 0.5 microns), 0.5% dispersant (such as polymer wax), 0.3% compatible Add additives (such as polyethylene glycol 200) and 0.3% hindered phenolic antioxidant (such as antioxidant 2,6-di-tert-butyl-4-methylphenol) into the high-speed mixer and stir evenly. Perform tape casting or extrusion molding to obtain the product, and perform performance testing on it.

Embodiment 3

[0026] A PC, PBT reflective material, according to the ratio of 76% polybutylene terephthalate, 20% calcium carbonate (average particle size of 5 microns), 2% dispersant (such as stearic acid), 1.2% compatibilizer (such as polyethylene glycol 400) and 0.8% antioxidant (such as antioxidant 1010) are added to a high-speed mixer and stirred evenly, and cast or extruded to obtain the product. Test its performance.

Abstract

The invention provides a PC and PBT reflective material. The PC and PBT reflective material comprises the following components in percentage by mass: 38% to 76% of carrier polyester resin, 20% to 60% of a micropowder filler, 0.5% to 2% of a dispersant, 0.3% to 2% of a soluble additive and 0.2% to 0.8% of an antioxidant. Correspondingly, the invention further provides a preparation method of the reflective material. Compared with the prior art, the technical scheme of the invention can be directly formed and used, the reflectivity can reach up to 99.0%, and the PC and PBT reflective material does not need to be stacked to be formed in layered manner, has simple production process and high production efficiency, and is suitably used as the reflective material of components of a liquid crystal display, an illuminating implement or a lighting billboard and the like.

Description

technical field [0001] The invention relates to the field of optical materials, in particular to a PC and PBT reflective material, which can be suitably used as reflective materials for components such as liquid crystal displays, lighting appliances or illuminated billboards, etc. PC (polycarbonate) reflective materials are used in liquid crystal display backlight modules The most widely used group. Background technique [0002] Reflective materials are used in various fields such as liquid crystal displays, lighting fixtures, and illuminated signboards. Recently, in the field of liquid crystal displays, the size of the device and the improvement of the display performance have been developed, at least it is required to supply more light to the liquid crystal to improve the performance of the backlight unit, and the reflective material is also required to have more excellent light reflection. sex. [0003] Among the existing reflective materials, PET foaming technology is ...
