| 摘 要： | 以玉米淀粉为原料,通过双氧水氧化降解和环氧氯丙烷交联改性,制得了可用于尿素缓释肥料的淀粉基包膜材料,并用扫描电镜（SEM）和红外光谱（FT-IR）测试了化学改性对淀粉结构的影响。实验结果表明,制备氧化/交联改性淀粉的较好条件为：双氧水1.0wt%,环氧氯丙烷4.0wt%。氧化/交联改性后,淀粉基包膜材料的吸水率从190%降为84%,可以用于制备尿素缓释肥料。当包膜材料用量为20wt%时,尿素缓释肥料的性能最佳。

| Abstract: | Coating materials,which could be used to produce urea slow-release fertilizer,were prepared with maize starch as initial materials through hydrogen peroxide oxidization and epichlorohydrin crosslink method,respectively.Effects of double-modification on characteristic of starch particles was also investigated by Fourier transform infrared spectroscopy(FT-IR) and scanning electron microscope(SEM).Results showed that better conditions to prepare double-modified starch could be obtained when mass fractions of h... |
