Polycarbonate filled composite material

Abstract

The invention discloses a polycarbonate filled composite material. The polycarbonate filled composite material is characterized in that: the polycarbonate filled composite material comprises the following components, by weight, 30-90% of a polycarbonate, 5-50% of titanium dioxide, 0.0001-5% of a fluorescent whitening agent, 0.001-15% of a high wavelength region brightening agent, and 0-50% of other fillers and assistants, wherein the high wavelength region brightening agent is a compound containing heteroatoms. The polycarbonate filled composite material has the following beneficial effects: the polycarbonate filled composite material which possesses excellent light reflection performances in a full waveband through adjusting proportions of the components can be adapted to different types of light sources, especially a reflector panel in an LED backlight module and a reflector lampshade of an LED lamp holder, as a reflection material; and the polycarbonate filled composite material has the advantages of consumption saving and convenient making, is well received and is recommended because of the convenient processing technology and molding when the polycarbonate filled composite material is applied to the light reflection material.

Description

technical field [0001] The invention relates to a polycarbonate filled composite material with high light reflection performance. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. Polycarbonate has become the fastest growing general-purpose engineering plastic due to its structural properties, which have excellent toughness, transparency, and self-extinguishing properties. As a part of the LED industry, light reflective materials have developed in the form of metal plates, metal foil composite plastic sheets, metal vapor-deposited plastic sheets, and foamed and stretched polyethylene terephthalate (PET) films. These sheets cannot be easily formed into molded articles, and processing is cumbersome. At present, polycarbonate can be used as a light reflection material (light reflection PC), because polycarbonate resin has excellent mechanical properties, electrical properties, trans...
