(57) [Summary] [Structure] (A) It is represented by the following general formula (1) and has an amino equivalent of 10,000 to 200,000 g / mol and a viscosity at 25 ° C. of 10: An amino-modified silicone oil having a viscosity of 100,000 centistokes, [In the formula, R 1 is —R 3 —NH 2 or —R 3 —NHR 4 —NH 2 (Wherein R 3 and R 4 are the same or different alkylene groups having 1 to 8 carbon atoms), R 2 is an unsubstituted or substituted monovalent hydrocarbon group having 1 to 6 carbon atoms, a and b Is 0.0001 ≦ a ≦ It is a number that satisfies 0.01 and 1.95 ≦ a + b ≦ 2.20. ] (B) A silicone grease comprising a thickener is provided. According to the present invention, it is possible to obtain a silicone grease having excellent heat resistance and cold resistance. |
