摘要
采用氧化淀粉和3次投加尿素进行改性的工艺合成了改性磺化三聚氰胺脲醛树脂抑尘剂。测量了抑尘剂中游离甲醛含量、黏度大小,并对其进行了IR、热稳定性能分析。结果表明,改性后抑尘剂中游离甲醛含量有所降低,黏度和保水性能都有所提高。同时,对该抑尘剂的固沙抑尘效果进行了研究,证明该抑尘剂是适于室外抑尘使用的固化性能较好的抑尘剂。
The method of urea for three times and oxidized starch was used to synthesize dust depressor of sulfonated melamine-urea-formaldehyde resins, Measured the content of free formaldehyde, viscosity, IR and TG. The results showed that the modified dust depressor has low content of free formaldehyde,high viscosity and high water retention, At the same time, study on the applied capability of the resins as a sand-fixation and dust depressor, proved it has good solidifled capability and it is fit for as outdoor dust suppression.
