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

Abstract

The invention provides a polystyrene reflection material.The polystyrene reflection material is prepared from, by mass, polystyrene 28%-66%, a micro powdery filler 30%-70%, a dispersant 0.5%-2%, a soluble additive 0.3%-2% and an antioxidant 0.2%-0.8%.Accordingly, the invention also provides a preparation method of the reflection material.Compared with the prior art, the polystyrene reflection material can be directly formed and used by the adoption of the technical scheme, the reflectivity can be up to 99% or above, stacked and layered forming is not needed, a production process is simple, the production efficiency is high, and the polystyrene reflection material is suitable for liquid crystal displays, lighting apparatuses or lighting billboards and other constituent parts.

Description

technical field [0001] The invention relates to the field of optical materials, in particular to a PS (polystyrene) reflective material, which can be suitably used as a reflective material for components such as liquid crystal displays, lighting fixtures, or illuminated billboards. 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 existing reflective materials, there is a reflective film for liquid crystal displays using a white polyester film mainly made of an aromatic polyester resin. However, when an aroma...
