摘要
将淀粉改性制得性能优异的双醛淀粉 ,代替甲醛与尿素缩合反应 ,合成出全新无毒的脲 -双醛淀粉胶粘剂。讨论了双醛淀粉与尿素的反应机理 。
The dialdehyde starch which has excellent property was prepared by mo difying starch.We used dialdehyde starch to condense with urea instead of formal dehyde and synthesized a new and nontoxic urea- dialdehyde starch glue.The react ion mechanism of dialdehyde starch and urea was discussed and the effect factors were generalized and analysed.
