Heat-conducting silicone grease and manufacturing method thereof

Abstract

The invention discloses heat-conducting silicone grease and a manufacturing method thereof. The heat-conducting silicone grease can be applied onto an LED (light-emitting diode) lamp by coating to improve heat dissipation efficiency, and is manufactured from the following raw materials in percentage by weight: 10 to 20 percent of nano-modified heat-conducting filler, 10 to 15 percent of nitride powder, 40 to 50 percent of oxide filler, 5 to 20 percent of silicone oil and 5 percent of assistant; the manufacturing process of the heat-conducting silicone grease is as follows: weighing needed silicone oil and assistant according to weight percentage, placing into a stainless steel mixing tank for heating, so as to enable the silicone oil and assistant to disperse at high speed, heating to raise the temperature to 50 to 80 DEG C, adding a proper amount of nano-modified heat-conducting filler, nitride powder, and oxide filler, performing high-speed stirring, then starting a vacuum machine to perform vacuum pumping while stirring, after the stirring and vacuum pumping are performed for 60min, placing the heat-conducting silicone grease in the stainless mixing tank onto a grinder for grinding to enable the heat-conducting silicone grease to be finer and more uniform, and package can be performed after grinding.

Description

technical field [0001] The invention relates to the technical field of silicone grease, in particular to a heat-conducting silicone grease and a preparation method thereof. Background technique [0002] As we all know, LED lamps are widely used because of their advantages such as energy saving, low carbon, long life, good color rendering, high luminous efficiency, good luminous effect, and fast response. The hoarding of the LED lamp beads can easily lead to damage and affect the light decay of the LED lamp beads, which directly affects the service life of the LED lamp. Therefore, the quality of the heat dissipation effect is directly related to the luminous effect and service life of the lamp. The problem is that the existing LED lamps generally only carry out various heat dissipation designs on the heat dissipation structure. The heat dissipation structures are varied, the structures are cumbersome and complex, and the processing procedures are complicated, which limits the...

Problems solved by technology

[0002] As we all know, LED lamps are widely used because of their advantages such as energy saving, low carbon, long life, good color rendering, high luminous efficiency, good luminous effect, and fast response. The hoarding of the LED lamp beads can easily lead to damage and affect the light decay of the LED lamp beads, which directly affects the service life of the LED lamp. Therefore, the quality of the heat dissipation effect is directly related to the luminous effect and service life of the lamp. The problem is that the existing LED lamps generally only carry out various heat dissipation designs on the heat dissipation structure. The heat dissipation structures are varied, the structures are cumbersome and complex, and the processing procedures are complicated, which limits the structural design of the LED lamps, making it difficult for the structural design of the LED lamps to be simplified. Development in the direction of portability

Currently on the market, there is no coating that can be coated on electronic devices such as LED lamp beads and have a high-speed heat dissipation effect
