NOVELTY - Thermally conductive silicone gel, comprises 40-70 pts. wt. vinyl silicone oil, 0.5-3 pts. wt. hydrogen-containing silicone oil, 0.5-25 pts. wt. alkoxy silicone oil (I), 400-2200 pts. wt. thermally conductive fillers, 1-5 pts. wt. catalysts and 0-7 pts. wt. optional pigments. USE - Used as thermally conductive silicone gel. ADVANTAGE - The silicon gel has higher thermal conductivity and more stable performance after long-term aging, ensuring that it can always maintain high heat dissipation efficiency during long-term use, and has strong reliability. DETAILED DESCRIPTION - Thermally conductive silicone gel, comprises 40-70 pts. wt. vinyl silicone oil, 0.5-3 pts. wt. hydrogen-containing silicone oil, 0.5-25 pts. wt. alkoxy silicone oil of formula (I), 400-2200 pts. wt. thermally conductive fillers, 1-5 pts. wt. catalysts and 0-7 pts. wt. optional pigments. R11, R12and R13= alkoxy group of (OCaH2a+1); a, b, a', b', a'', b'' = 0-16; R14and R15= alkyl group of (CbH2b+1); R16, R17and R18= alkoxy groups of OCa'H2a'+1or all alkyl groups of Cb'H2b'+1; and n = 4-50. Provided that: Any two of R16, R17and R18is alkoxy group of OCa"H2a"+1or alkyl group of Cb"H2b"+1and remaining one is vinyl group. An INDEPENDENT CLAIM is also included for preparing thermally conductive silicone gel comprising (i) mixing vinyl silicone oil, hydrogen-containing silicone oil and alkoxy silicone oil uniformly to obtain a first mixture, (ii) uniformly mixing the first mixture, thermally conductive filler and optional pigment obtained in step (i) to obtain a second mixture, and (iii) stirring and mixing second mixture and catalyst uniformly at 100-120 ℃ under vacuum conditions to obtain thermally conductive silica gel.
