Silicone composite composition comprising natural graphite and alumina and preparation method of thermal conductive grease comprising the same

摘要

The present invention relates to a thermally conductive grease and a method including a high viscosity silicone resins, ultrasonic disruption of natural graphite and alumina, thermally conductive grease according to the present invention is a silicone resin and a thermally conductive filler, natural graphite and alumina (Al ₂ O ₃ ), the silicone resin has a viscosity of 900-1100 cSt, and the natural graphite has an effect of improving the heat radiation characteristic by ultrasonic disintegration for 25-35 minutes at a frequency of 400-500 Hz, and furthermore, a carbon fiber is added There is an effect that the heat radiation characteristic is further improved.
