Embodiment 1

[0031] The preparation of embodiment 1 lampshade material

[0032] 100 parts of polycarbonate; 8 parts of toughening agent (specifically toughening agent EM500); 8 parts of multi-walled carbon nanotubes; 2 parts of antioxidant (specifically antioxidant 1010); 2 parts of agent UV531); 2 parts of bismaleimide; 0.5 part of silane coupling agent (specifically silane coupling agent kh550); 0.5 part of lubricant (specifically calcium stearate).

[0033] Preparation method: put polycarbonate, toughening agent, multi-walled carbon nanotubes, antioxidant, ultraviolet absorber, bismaleimide, silane coupling agent, and lubricant into a mixer and mix evenly, and then mix The uniformly mixed material is fed into a twin-screw extruder for melt extrusion and granulation to obtain the high-strength, easy-to-clean and aging-resistant LED lampshade material.

[0034] The impact resistance of the lampshade material is enhanced by adding a toughening agent to the LED lampshade material; the prem...

Abstract

The invention relates to the technical field of high-molecular materials, and particularly discloses a high-strength, easily-cleaned and ageing-resistant LED (light-emitting diode) lampshade materialand an LED lamp with the same. The LED lampshade material comprises, by weight, 80-120 parts of polycarbonate, 5-10 parts of toughening agents, 5-10 parts of multi-walled carbon nano-tubes, 1-3 partsof antioxidants, 1-3 parts of ultraviolet absorbents, 1-3 parts of bismaleimide, 0.5-2 parts of silane coupling agents and 0.1-1 part of lubricating agents. According to the LED lampshade material, the toughening agents are added, impact resistance of the lampshade material can be enhanced, the antioxidants and the ultraviolet absorbents are added, early aging of the LED lampshade material can beprevented, and the multi-walled carbon nano-tubes are added, so that the surface of a lampshade can be easily cleaned even if dust is absorbed on the surface of the lampshade under the action of static electricity. Besides, the lampshade material has excellent heat conducting and cooling effects. As the lampshade material is high in strength, resistant to ageing and easy to clean and has a coolingfunction, and the lampshade material is applied to outdoor high-power LED street lamps.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-strength, easy-to-clean and aging-resistant LED lampshade material and an LED lamp containing the lampshade material. Background technique [0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver or gold wires, and sealed with epoxy resin around it to protect the inner core wire. function, and finally the shell is installed. At present, LEDs are widely used in various fields in life and industrial production, such as street lamps on the street. [0003] As an outdoor LED lamp, there are high requirements for the lampshade material of the LED lamp. For example, the outdoor LED lampshade material needs to have the characteristics of high impact strength, easy cleaning and weather resistance; in addition, the heat dissipa...
