Abstract

The invention discloses a composition of a light-diffusing material and a preparation method of the composition. The composition comprises, by weight, 30-45% of polycarbonate polymers, 55-65% of polystyrene polymers, 0.6-0.8% of light-diffusing agent, 0.5-5% of compatilizers, 0.3-0.8% of antioxidant and 0.2-0.6% of weather-proofing agent. The light-diffusing PC / PS alloy material has the advantagesof high mobility, light transmittance, haze and temperature resistance.

Description

technical field [0001] The invention relates to the technical field of PC / PS alloy materials, in particular to a composition of a light diffusion material and a preparation method thereof. Background technique [0002] In recent years, there have been many studies on light-diffusing PCs. Most of the light diffusion plates are based on polycarbonate polymer (PC), and different types of diffusing agents are added to obtain different effects. With rising raw material prices, LED manufacturers are looking for alternatives to light-diffusing PC. At this time, a light-diffusing PS material appears. The light-diffusing PS material is based on polystyrene, which can greatly reduce the cost of the lampshade material. However, not all environments are suitable for the use of light-diffusing PS. The long-term heat resistance of light-diffusing PS is only between 66°C and 75°C, and it will deform when the LED is lit for a long time. [0003] Japan's Idemitsu Co., Ltd. saw the market ...
