Abstract

The present invention discloses a light-diffusing flame-retardant polycarbonate material for LED lighting, wherein the light-diffusing flame-retardant polycarbonate material comprises (by weight) the following raw materials. According to the present invention, the organic light diffusing agent is added to the composite substrate, such that the light is soft, the stability is good, the particles are tightly bound, and the uniform system is easily formed; through the matched cooperation of the organic light diffusing agent and the fluorescent brightener, the light transmittance can be improved, and the light diffusion effect can be improved; and the product has the good gloss, the interface combination degree of the matrix resin is enhanced with the compatibilizer, the impact strength is increased, the product has the toughness, and the flame retardant property is provided for the product through the flame retardant agent.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a light-diffusion flame-retardant polycarbonate material for LED lighting, and also relates to a preparation method of the light-diffusion flame-retardant polycarbonate material. Background technique [0002] Light-emitting diodes (LEDs) have the characteristics of energy saving, environmental protection, long life, and environmental friendliness when they are used as lighting fixtures. become a research hotspot in this field. [0003] Light diffusion material is also called light scattering material or astigmatism material. Light-diffusing particles with different refractive indices of the substrate are prepared by dispersing them in a transparent substrate. The application of light-diffusing materials to LED lighting technology is a new application field opened up in recent years. [0004] The main indicators for evaluating the performance of light scattering materi...
