摘要
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),通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.
This paper introduces the synthesis and characterization of side chain amino-modified silicone oil. Side chain amino-modified silicone oil is 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) are obtained during the process of experiment.Furthermore,the structure and properties of side chain amino-modified silicone oil is characterized by various analytical techniques,including Fourier transform infrared spectroscopy(FT-IR), viscosity meter,and thermogravimetric analyzer.According tOthe analytical 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.
