Embodiment approach 1

[0030] In order to improve the thermal conductivity of the insulating and thermally conductive material and improve the heat dissipation efficiency of the LED, an embodiment of the present invention provides an insulating and thermally conductive additive. The insulating and heat-conducting additive includes zero-dimensional insulating and heat-conducting fillers, one-dimensional insulating and heat-conducting fillers and two-dimensional insulating and heat-conducting fillers. 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. A third group is connected to the two-dimensional insulating and heat-conducting filler. Both the first group and the third group can undergo a cross-linking reaction with the second group, so that a three-dimensional insulating and heat-conducting network is formed among the zero-dimensional insulating and heat-conducting...

[0053] Specifically, the mass ratio of the polymer matrix to the insulating and heat-conducting additive is (30:70)˜(65:35). At this time, the insulating and heat-conducting additive can be fully dispersed in the polymer matrix, so that a three-dimensional insulating and heat-conducting network can be constructed in the polymer matrix, and the heat-conducting performance of the insulating and heat-conducting material can be further improved. At the same time, it can also ensure that the insulating and heat-conduc...

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...
