摘　　要：利用动态热机械分析仪（DMA）,对不同合成工艺条件下制备的氨基共缩合树脂性能进行了分析。基于DMA分析仪的优势,重点从固化特征方面对氨基共缩合树脂进行了表征。结果表明,不同合成工艺路线,对MUF共缩合树脂的固化特征温度有不同影响,而且,当固化剂存在时,不同氨基树脂又表现出了不一样的固化历程,有助于树脂固化速度的提高。通过测试不同固化剂加量条件下的DMA特征参数,结果显示氯化铵作为固化剂时,加入量控制在0.5%～1.0%之间,可获得优良的胶层性能。The performances of amino co-condensation resin synthesized with different procedures were analyzed by DMA.Taking advantages of DMA instrument,amino co-condensation resin was examined with the emphasis of curing characteristics.The results showed that,there existed some relationships between curing characteristic temperature MUF co-condensation resin and cooking process,moreover,when curing agent was added,three MUF resins showed different curing processes,and the curing velocity was improved.By comparing DMA characteristic parameters at different curing agent additions,the results suggested that the performance of glue line was the best when ammonium chloride addition was 0.5%～1.0%.
