摘　　要：玉米淀粉胶黏剂存在着稳定性差、防潮性不好等缺点需要改进。利用聚丙烯酰胺对玉米淀粉胶进行掺杂改性,研究了在不同配比胶黏剂中加入聚丙烯酰胺对初粘性、黏度、干燥速率、返潮速率等性能的影响。结果表明:加入助剂,在一定配比时可以提高玉米淀粉胶的黏度、干燥速率,并降低其返潮速率。实验结果显示在氧化淀粉胶黏剂中聚丙烯酰胺的最佳加入量为淀粉质量的0.5%。Corn starch adhesives have some shortcomings need to be improved , such as instability , poor moisture resistance , etc.The corn starch adhesive was doped by polyacrylamide to improve its performance.The influence of polyacrylamide e on the properties of adhesive have been investigated by analyzing the initial adhesion , viscosity , the influence of the drying rate , get damp rate of starch adhesive and so on.The results showed that the add fertilizer could improve the viscosity , drying rate , and reduce its damp rate of adhesive.The experiment showed that the optimum condition was 0.5%of starch quality.
