摘要
采用差示扫描量热法(DSC)对不同固化体系下的低毒脲醛(UF)树脂的固化特性进行了研究。试验结果表明:在不同固化体系下,低毒UF树脂的固化反应起止温度和所需的活化能是不同的。在固化体系C下,低毒UF树脂的固化反应的起始温度低,放出的热量多,固化反应所需活化能最低,说明固化体系C对低毒UF树脂的固化反应促进效果较好。
Curing characteristics of low-toxicity urea-formaldehyde（UF） resin in different curing systems were studied by using differential scanning calorimetry（DSC）.Test results showed that the initial or terminal temperature and activation energy needed for curing reaction of low-toxicity UF resin were different in different curing systems.Under curing system C,the initial temperature and activation energy needed for curing reaction of low-toxicity UF resin were the lowest of all experimental conditions,and exothermic heat were the most in the reaction, which showed the acceleration effect of curing system C on low-toxicity UF resin was the best.
