High heat conducting insulating silicon grease and its manufacturing method

Abstract

An insulating silicon cream with high heat conductivity is prepared from the mixed aluminium nitride particles which high heat conductivity (3.0 W / m.k) and high insulating property and methyl silica oil through proportionally mixing, ball grinding, vacuum stirring and removing air. Said mixed aluminium nitride particles is composed of big particles (12 microns) and small particles (1.5 microns).

Description

technical field

[0001] The invention relates to a high thermal conductivity insulating silicone grease and a manufacturing method thereof, belonging to the technical field of new materials. Background technique

[0002] Effectively removing the heat generated by electronic equipment is related to the reliability and life of the product. At present, electronic products are in the trend of densification and miniaturization, and at the same time, higher requirements are put forward for heat dissipation or heat conduction and insulation. On the other hand, the application of heat-conducting insulating silicone grease can transfer the heat generated by components, especially high-power devices, to the surrounding environment through the radiator, thereby improving the development of densification and miniaturization of power electronic products. Therefore, thermally conductive insulating silicone grease is widely used in aerospace, aviation, communication, and power electronics ...
