Embodiment 1

[0044] (1) Preparation of flame retardant masterbatch:

[0045] 79.4 parts of polycarbonate (produced by Teijin, model 1225WP, MI 7g / 10min, pretreated at 120°C for 3 hours, in powder form), 0.2 parts of lubricant (produced by Italian hair base, model is PETS AP) and 0.4 parts of antioxidant (obtained by mixing antioxidant 168 and antioxidant 1076 at a weight ratio of 1:1, antioxidant 168 is a product of the model AT-168 produced by Jinhai Yabao, the antioxidant Agent 1076 is selected from Jinhai Yabao’s model AT-76) and stirred in a high-speed stirring pot (950r / min) for 5min. After preliminary mixing, it was added to the twin-screw extruder from the first feeding port, 20 parts The organic silicon flame retardant (produced by Japan Shin-Etsu Chemical Industry Co., Ltd., model KR2710) is added to the fifth barrel of the twin-screw extruder through the liquid feeding pump from the fifth feeding port (that is, along the feeding section to the machine head) The fifth reaction se...

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...
