中文摘要:
      以淀粉为主要原料,制备三聚氰胺甲醛树脂(MF),改性淀粉胶粘剂。用红外光谱表征改性的每个阶段,验证其改性机理。X- ray衍射说明了MF对淀粉的结晶度影响不大,MF主要是交联改性的淀粉的无定型区;扫描电镜显示MF对淀粉颗粒形成塑化,改变了淀粉颗粒的表面形貌,通过交联形成网状结构。结果表明,MF改性提高了淀粉胶粘剂的耐水性与稳定性,常温下保存7d后,其耐水时间、粘度分别为96 h和500 mPa.s。
英文摘要:
      Modified starch adhesive was prepared by melamine formaldehyde resin (MF). Modification was characterized by lR at each stage and modification mechanism was verified. X-ray diffraction showed that MF can crosslink amorphous area, but hardly effects on the degree of crystallinity of starch. SEM analysis showed that MF can plasticize starch granules, change surface morphology of starch granules and form network structure by cross-linking. The results showed that the MF improves the water resistance and stability of starch adhesive. At room temperature the modified starch adhesive can keep for 7 days, and its water resistance is 96 h and its viscosity is 500 mPa.s.
