| 摘 要： | 采用各种分离、测试手段剖析可剥蓝胶的成分及含量。首先借助红外光谱(FT-IR)法确定其基体树脂为氯醋树脂,再通过核磁氢谱(1H-NMR)法确定其固化体系和基体树脂的成分,随后用凝胶渗透色谱(GPC)法验证了基体树脂和固化体系的成分及含量;此外,利用X射线荧光光谱法确定了润滑体系和颜填料体系的成分及含量;最后通过热失重分析(TGA)法将各成分的含量进一步细化。结果表明:该可剥蓝胶中各成分及含量(以质量分数计)分别为氯醋树脂60%~65%、环氧树脂(EP)10%~12%、甲阶酚醛树脂8%~10%、邻苯二甲酸酯8%~10%、硬脂酸钡1%~2%、磷酸三苯酯1%~3%、碳酸钙1%~2%、二氧化硅1%~2%和酞菁蓝0.5%~1%;还原试验证明各种分析结果有效可靠。
