NOVELTY - Thermally conductive silicone grease composition, comprises1-30 pts.wt. single-ended triethoxy silicone oil, 70-99 pts.wt. filler and 0.01-1 pts.wt. Coupling agent. USE - Thermally conductive silicone grease composition used for manufacturing of communication electronics, computers, radiators ADVANTAGE - The silicone grease has low viscosity, good flowability, good steel screen printing manufacturability and strong market application value. The content of low volatile substances in the heat-conducting silicone grease system is reduced, the application reliability of the silicone grease is improved, and cracking and gaps are prevented. The wetting effect of the silicone oil and the filler is enhanced, the filling ratio of the filler is greatly improved, the heat conduction network channel is enhanced, and the heat conduction effect is effectively improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation process of heat-conducting silicone grease, involves(1) heating double-planetary power stirrer to 80 ℃, respectively and sequentially adding the single-end triethoxy silicone oil and alkoxy titanate coupling agent into double-planetary power stirrer, and stirring for 15min to obtain a first mixture, where stirring speed is 20-40 r/min, and dispersion speed is 200-1000 r/min. S2, adding spherical aluminum powder of 12 microns, spherical silver powder of 2 microns and zinc oxide filler of 0.2 microns into first mixture respectively in sequence, and stirring for 60min to obtain second mixture, where stirring speed is 20-60 r/min, dispersion speed is 200-1000 r/min, and stirring temperature is 105 ℃. S3, adding black color paste into second mixture, and integrally stirring for 30min to obtain a final mixture, where stirring speed is 20-60 r/min, dispersing speed is 200-1000 r/min, and stirring temperature is 120 ℃, in process, simultaneously starting vacuumizing device and maintaining vacuumizing for 20 min where, vacuum degree is set to-0.095 to-0.1 Mpa, (4) standing whole final mixture to normal temperature, transferring mixture to a pressing machine, and filling to obtain heat-conducting silicone grease.
