Abstract

The invention relates to the field of high molecular composite materials, and particularly discloses a transparent low-temperature-resistant halogen-free low-smoke inflaming-retarding polycarbonate composite material, which is prepared from the following components in percentage by weight: 45 to 90 percent of branch-chain-shaped polycarbonate resin, 5 to 50 percent of siloxane copolymeric PC (Polycarbonate) resin, 0.1 to 1 percent of sulfonate inflaming retarding agent, 0.05 to 1 percent of polysiloxane inflaming retarding agent, 0.1 to 2 percent of light diffusant and 0.5 to 1.5 percent of aid. The transparent low-temperature-resistant halogen-free low-smoke inflaming-retarding polycarbonate composite material has the advantages that the light-diffusing PC composite material provided by the invention also has the characteristics of being resistant to low temperature, low in smoke density, halogen-free and inflaming-retarding besides having the basic optical property of light-diffusing PC; higher inflaming retarding class and lower smoke density can be achieved.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to a low-temperature-resistant, low-smoke, flame-retardant polycarbonate composite material and a preparation method thereof. Background technique [0002] Due to its advantages of environmental protection and energy saving, LED lights gradually replace incandescent and fluorescent lamps, but their luminous intensity per unit area is too high, which is very dazzling when viewed directly, causing glare and visual discomfort. Therefore, a light-transmitting cover is urgently needed, and the light is softened and uniformed through the lamp cover. Polycarbonate (PC) is widely used in the field of LED lampshades because of its excellent weather resistance, high impact resistance, excellent electrical insulation, high light transmittance, and less light energy loss. [0003] Light-diffusing PC is to add a spherical light-diffusing agent to the PC resin and disperse it evenly in...
