Anti-glare flame-retardant polycarbonate material, and preparation method and application thereof

Abstract

The invention discloses an anti-glare flame-retardant polycarbonate material which comprises the following components by weight percent: 85-95 percent of polycarbonate, 2-12 percent of flame retardant, 0.1-1 percent of flame-retardant synergist, 0.1-5 percent of anti-glare agent, 0.3-2 percent of anti-ultraviolet agent, 0.05-3 percent of blue light absorbent, 0.2-3 percent of antioxidant and 0.2-2 percent of lubricating agent. The anti-glare flame-retardant polycarbonate material not only has an excellent anti-glare function, but also has higher light transmittance, and is capable of absorbing the blue wave band of the LED lighting spectrum at the same time. The invention further discloses a preparation method of the anti-glare flame-retardant polycarbonate material, which comprises the following steps: firstly preparing flame-retardant masterbatches, organic silicon microbead anti-glare masterbatches and blue light absorption masterbatches, and then preparing the anti-glare flame-retardant polycarbonate material, so that the performance anti-glare flame-retardant polycarbonate material is improved. The anti-glare flame-retardant polycarbonate material is particularly suitable for preparing an optical housing for LED lighting.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an anti-glare and flame-retardant polycarbonate material with special functions, a preparation method thereof, and an application in preparing an optical housing for LED lighting. Background technique [0002] Semiconductor lighting (light-emitting diode (Lighting Emitting Diode), hereinafter referred to as "LED") is a new type of high-efficiency solid light source. Compared with traditional lighting fixtures, its power consumption is only 1 / 10 of incandescent lamps, and its There are no ultraviolet and infrared rays in the spectrum, and the service life is as long as 60,000 to 100,000 hours, which is 100 times that of incandescent lamps, and does not contain heavy metal mercury in energy-saving lamps. In view of its characteristics of energy saving, environmental protection, long life, maintenance-free and easy control, LED lighting appliances are recognized as one of the most p...

AI Technical Summary

Problems solved by technology

Although the flame retardancy of the material is improved by adding a flame retardant, the anti-glare property is simply improved by ultraviolet absorbers and polycarbonate, and its optical performance is still poor, especially when used for optical housings for LED lighting. The emitted light is not soft enough, not uniform enough, the comfort is poor, and there will still be "blue light hazard" produced by blue LED chips
