摘要
贮藏几年的低分子聚酰胺作为室温固化剂和环氧成浇灌绝缘材料,发现固化产物的抗剪、耐水性降低、测量发现其胺值下降,经红外光谱分析,用它和环氧固化。
low molecule polyamide,which has been stored about 12 years was used to cured epoxy resin as filling compounds. Its shear strength,water resistance were decreased,its number of amine bases decreased too. y using IR,the left epoxy bases cured by the polyamide much more than that do by new one coming form factory recently. At 990cm -1 peak value of amine bases differ much each other.
