The invention discloses low-viscosity high-thermal-conductivity silicone grease as well as a preparation method and application thereof. The low-viscosity high-thermal-conductivity silicone grease is prepared from the following components in parts by weight: 1 to 10 parts of silicone oil, 2 to 4 parts of triethyltrimethoxy-terminated polydimethylsiloxane treating agent, 10 to 20 parts of zinc oxide, 20 to 30 parts of fine aluminum oxide and 50 to 70 parts of coarse aluminum oxide. The heat-conducting silicone grease prepared according to the formula is low in viscosity, good in construction performance, good in viscosity stability and free of cracking during high-temperature aging. The radiator can be widely applied to the fields of lamp heat dissipation, processor heat dissipation and the like. 本发明公开了一种低粘度高导热硅脂及其制备方法和应用；所述低粘度高导热硅脂包括以下重量份的组分：硅油1~10份，三乙基三甲氧基封端聚二甲基硅氧烷处理剂2~4份，氧化锌10~20份，细氧化铝20~30份，粗氧化铝50~70份。通过上述配方制得的导热硅脂，粘度低，施工性能好，粘度稳定性好，高温老化不开裂。可广泛应用于灯具散热、处理器散热等领域。
