The insulating and heat-conducting additive comprises a zero-dimensional insulating and heat-conducting filler, a one-dimensional insulating and heat-conducting filler and a two-dimensional insulating and heat-conducting filler; the zero-dimensional insulating and heat-conducting filler is connected with a first group, the one-dimensional insulating and heat-conducting filler is connected with a second group, and the two-dimensional insulating and heat-conducting filler is connected with a third group. The first group and the third group can be subjected to cross-linking reaction with the second group, so that a three-dimensional insulating heat-conducting network is formed among the zero-dimensional insulating heat-conducting filler, the one-dimensional insulating heat-conducting filler and the two-dimensional insulating heat-conducting filler. The insulating heat-conducting additive provided by the invention is used for improving the heat-conducting property of the insulating heat-conducting filler.

Description

technical field [0001] The invention relates to the technical field of light-emitting diodes, in particular to an insulating and heat-conducting additive, an insulating and heat-conducting material, a preparation method thereof, and a light-emitting diode. Background technique [0002] Light-emitting diode (Light-Emitting Diode, abbreviated as LED) is a light-emitting device that can convert electrical energy into light energy. It has the advantages of long life, low power consumption, high efficiency, energy saving and environmental protection, and is widely used in the lighting field. [0003] However, LEDs also generate a lot of heat energy in the process of converting electrical energy into light energy. The accumulation of heat energy will increase the temperature of the LED, resulting in a reduction in the working efficiency and service life of the LED. [0004] At present, in order to improve the heat dissipation efficiency of the LED, the shell of the LED is general...
