Problems solved by technology

Compared with ordinary daylight lighting and advertising signboard light box lighting, LED lighting and liquid crystal display devices require higher light reflectivity (95%-97%) and light reflectors with good scattering effects in order to solve whether it is side entry or direct entry. Light can improve the utilization rate of the front light source; this kind of light reflection plate also requires thin thickness and light weight, but the existing technology is difficult to meet the needs

Abstract

The invention discloses a single-layer two-way stretch light reflex polyester film which is characterized in that the single-layer two-way stretch light reflex polyester film is manufactured from 30 parts of A component by mass, 60-80 parts of B component by mass and 1-5 parts of C component by mass through steps of mixing, extrusion and two-way stretch forming, wherein the A component is formed by mixing 3-48 parts of inorganic particles by mass and 5-50 parts of A resin by mass; the B component is formed by mixing 50-70 parts of polyester resin by mass and 1-20 parts of compatilizer by mass; and the C component is formed by mixing 0.05-1 parts of organic ultraviolet absorbent by mass and 0.5-5 parts of antistatic agent by mass. The thickness of the film is 0.1mm-0.3mm, and the film is manufactured by extruding via an extruder, two-way stretch and heat setting. The single-layer two-way stretch light reflex polyester film is particularly applicable to the manufacture of a light reflex member in a liquid-crystal display device.

Description

technical field [0001] The invention relates to a bubble-in-bubble structure polyester film material for a light reflection plate and its preparation, in particular to a single-layer biaxially stretched light-reflective polyester film and a manufacturing method thereof. The single-layer biaxially-stretched light-reflective polyester film of the invention It is especially suitable for use in liquid crystal display devices. Background technique [0002] In the prior art, the light reflector material has a wide range of uses, and it can be used in general daylight lighting, LED lighting, and advertising signboard light box lighting. In order to achieve high reflectivity, Chinese patent application 200780032366.5 uses incompatible polymers and polyester blends, and biaxially stretches to make a film for light reflection boards. The material structure of the film forms a reflection effect on light A large number of microbubbles, thereby improving the light reflection efficiency....
