摘要

本文主要对侧链氨基改性硅油的合成方法和性能表征进行研究。合成的侧链氨基改性硅油由六甲基二硅氧烷（MM）、八甲基环四硅氧烷（D4）和N,β-氨基乙基-γ-氨丙基甲基二甲氧基硅烷（KH-602）,过开环聚合反应制备而成。实验过程中，通过对粘度和产率的对比，得到MM，KH-602和四甲基氢氧化铵在实验制备过程中的最佳当量比。通过平行实验，在优化MM，KH-602和四甲基氢氧化铵最佳当量比条件下，最终获得实验最佳反应条件。本文通过多种分析方法对制备的侧链氨基硅油的性能进行表征。主要是通过傅立叶变换红外光谱（FT-IR）对合成硅中含有的官能团进行测定；通过粘度仪对乳液粘度进行测定；通过热重分析仪对烘干后的硅油热稳定性进行分析等。根据分析测试结果表明该方法得到氨基的硅油具有较好的热稳定性，在碳纤维油剂的生产制备中具有十分重要的潜在应用价值。

Abstract:

This paper introduced the synthesis and characterization of side chain amino-modified silicone oil. Side chain amino-modified silicone oil was prepared by Hexamethyldisiloxane (MM), octamethycyclotetrasiloxane (D4) and N,β-aminoethy-γ-aminopropylmethy dimethoxysilane (KH-602) through ring-opening polymerization. Through the analysis of viscosity, yield, and parallel experiments, the optimal dosage of MM, KH-602 and tetramethylammonium hydroxide (equivalent ratio) were obtained during the process of experiment. Furthermore, the structure and properties of side chain amino-modified silicone oil was characterized by various analytical techniques, including Fourier transform infrared spectroscopy (FT-IR), viscosity meter, and thermogravimetric analyzer. According to the analytical test results, the side chain amino-modified silicone oil possess excellent thermal stability and has crucial potential application value in the production and preparation of carbon fiber oil.

Key words: amino silicone oil ring opening polymerization carbon fiber oil agent
