摘　　要：研究了非等温过程中改性低毒脲醛树脂固化体系和未改性脲醛树脂固化体系的固化行为,并研究了不同固化剂施用量对改性树脂固化的影响,对不同树脂体系固化后的结构进行了表征。结果表明,改性的UF树脂固化后的交联度大于未改性树脂固化后的交联度。The non-isothermal curing behaviours of modified low toxic urea-formaldehyde （UF） and untreated UF resins were investigated by means of FUR, DSC. The effects of the contents of different curing agents on the curing of the modified resin were also studied, and the structure of the cured resin was characterized. The results showed the degree of the crosslinking of the modified UF resin was higher than that of the untreated UF resin.
