The invention discloses a silicone oil shock absorber which comprises a shock absorber shell and compound silicone oil sealed in the shock absorber shell. The compound silicone oil is prepared from, by weight, 30-50 parts of methyl silicone oil, 30-50 parts of ethyl silicone oil, 1-2 parts of oily wax, 1-3 parts of trivalent cerium compounds, 1-3 parts of sodium carboxymethylcellulose (CMC-Na), 150 parts of base oil, 30-50 parts of SN, 2-5 parts of butyl octyl-diphenylamine, 2-5 parts of an extreme-pressure antiwear agent, 2-5 parts of fatty alcohol ester of styrene-maleic anhydride resin, 2-3 parts of Arabic gum, 1-2 parts of zinc naphthenate, 1-2 parts of aliphatic polyethenoxyamine, 1-5 parts of poly(alkyl methacrylates), 1-5 parts of glacial acetic acid, 1-3 parts of ferrocene, 1-5 parts of ethylene-propylene bipolymers and 1-3 parts of hectorite. In this way, the internal silicone oil is improved to be not prone to volatilization, and the better using performance is achieved.
