Study on Curing Characteristics of Low-Toxicity Urea-Formaldehyde Resin

Article Preview

Abstract:

Curing characteristics of low-toxicity urea-formaldehyde (UF) resin in different curing system were studied by differential scanning carlorimetry (DSC). Test results showed that the initial orterminal temperature and activation energy needed of curing reaction for low-toxicity UF resin were different in different curing system. The initial temperature of curing reaction for low-toxicity UF resin and activation energy were the lowest, and exotherm was most under curing system C, which showed the acceleration of curing system C on low-toxicity UF resin was best. The appropriate curing system can be optimized and applied for hot-press process in practical production by means of DSC to investigate curing characteristics of low-toxicity UF resin.
