| 中文摘要: |
| 目的 研究以三聚磷酸钠代替甲醛制备无甲醛淀粉胶黏剂。方法 以淀粉、聚乙烯醇和聚丙烯酰胺为原料，次氯酸钠为氧化剂，水为溶剂，三聚磷酸钠为交联剂，制备无毒环保型改性淀粉胶黏剂。通过单因素实验考察了聚丙烯酰胺用量、氧化剂种类、氧化剂用量、水用量等因素对淀粉胶黏剂性能的影响。结果 实验表明，在淀粉质量为9 g，聚丙烯酰胺质量为1 g，次氯酸钠为氧化剂且体积为2.5 mL，水体积为160 mL，pH值为8～9的条件下，所得淀粉胶黏剂的综合性能最好。结论 产品性能稳定、粘结效果好、无毒环保，适合在工业生产中大量使用。 |
| 英文摘要: |
| The work aims to research the preparation of formaldehyde-free starch adhesive with sodium tripolyphosphate instead of formaldehyde. A kind of environmental friendly starch adhesive was produced by using starch, polyvinyl alcohol (PVA) and polyacrylamide (PAM) as principal raw material, sodium hypochlorite as oxidizing agent, water as solvent, and sodium tripolyphosphate as cross-linking agent. Single-factor experiment was carried out to investigate the effect of main factors, such as mass of polyacrylamide, kind of oxidizing agent, mass of oxidizing agent and mass of water on starch adhesive. The results showed that the optimal parameters were 9 g starch, 1 g polyacrylamide, 2.5 mL sodium hypochlorite as oxidizing agent, 160 mL water and pH=8～9. In conclusion, the environmental friendly adhesive has stable performance and good bonding effect. It is suitable for use in industrial process. |
