Problems solved by technology

[0006] Polycarbonate (PC) is a kind of non-crystalline thermoplastic engineering plastics, together with ABS, POM, PA, and PBT, it is called the five general-purpose engineering plastics. PC materials have high strength, high rigidity, good dimensional stability, and excellent mechanical properties. Good impact resistance, high heat distortion temperature, good creep resistance and colorability, are widely used in aerospace, mechanical transportation, electronic appliances, construction transportation, information storage and many other fields with excellent comprehensive performance. PC resin has excellent transparency and high light transmittance, and has become the preferred substrate for LED light-scattering materials. However, in the prior art, light-diffusing materials prepared with PC as the substrate often use some inorganic particles to add them. Such particles Uneven distribution will lead to low light transmittance, and the overall performance of the material is single, making it difficult for lamps to meet diversified use needs

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...
