NOVELTY - High-efficiency thermally conductive gasket comprises 60-100 pts. wt. composite structure thermal conductive filler, 5-25 pts. wt. thermal conductive material arranged in one-dimensional structure orientation, 10-40 pts. wt. vinyl polyorganosiloxane, 3-20 pts. wt. hydrogen-containing silicone oil, 0.25-2 pts. wt. silane coupling agent and 0.01-0.2 pts. wt. platinum catalyst. The composite structure thermally conductive filler is a composite structure thermally conductive filler formed by uniformly coating nanoparticles with high thermal conductivity on a microsphere carrier. USE - Used as high-efficiency thermally conductive gasket. ADVANTAGE - The gasket forms a three-dimensional network path capable of quickly conducting heat by tightly stacking the surface of the microsphere, reduces the interface thermal resistance, and cooperating with the carbon fiber arranged in orientation, and improves the heat conducting efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the gasket, comprising (1) adding the micron-sized carrier and the nano-grade heat conducting filler with high heat-conducting coefficient into the high speed mixer to mix and disperse, and obtaining the heat-conducting filler of the composite structure after high speed dispersion, (2) placing the high speed dispersed composite structure heatconducting filler obtained in the step (1) and the heat- conducting material with one-dimensional structure orientation arranged in the vacuum stirrer, and vacuumizing for 10-30 minutes, removing air in the system, and stopping vacuumizing process, (3) uniformly mixing the vinyl polyorganosiloxane, silane coupling agent, terminal containing hydrogen silicone oil, catalyst in the vacuum stirrer, and vacuumizing and stirring for 10-60 minutes to obtain the slurry with fluidity, and (4) adding the slurry obtained in the step (3) into the orientation device, extruding the slurry at a flow rate of 0.1-50 cm/s to the rectangular mold in the 0.2-2 MPa pressure condition to form, solidifying, cooling and slicing to obtain the high-efficiency heat-conducting gasket.
