ABSTRACT:This paper deals with synthesis and characterization of amino silicone oil. The synthesis of amino silicone oil was made by Hexamethyldisiloxane (MM) octamethycyclotetrasiloxane (D4) and N,β-aminoethy-γ-aminopropylmethy dimethoxysilane (KH-602) through ring-opening polymerization. Fourier transform infrared spectroscopy (FT-IR) was used for the structure characterization. Its viscosity was measured by a rotary viscometer. Volatile matter content was measured by oven. Through the analysis of viscosity and yield, the optimal dosage of MM, KH-602 and Tetramethylammonium hydroxide was obtained. The optimal reaction conditions were obtained by different amounts of MM, KH-602 and Tetramethylammonium hydroxide. Results showed that amino silicone can be obtained by this method. Amino silicone oil has good performance as a carbon fiber oil agent.

Keywords:Amino silicone oil, ring-opening polymerization.
