| 中文摘要: |
| 目的 合成一种耐水性良好、 流动性高的包装用改性糊精胶黏剂 （MDA）。方法 以糊精、 三羟甲基三聚氰胺（TMM）和硼砂为原料， 利用交联共聚的方法制备MDA。分别研究三羟甲基三聚氰胺、 糊精和硼砂的配比及交联温度等4个变量对MDA的耐水性、 干燥速率、 初粘力、 固含量和黏度等5个性能指标的影响。结果 当硼砂质量分数为0.8%， TMM质量分数为16%， 交联温度为90 ℃时， MDA的耐水性达123 h以上。通过红外光谱分析证实了TMM与糊精发生了交联反应， 生成了MDA的结构。结论 利用TMM交联改性糊精， 提高了胶黏剂的耐水性与粘结强度， 所得的改性糊精胶黏剂可用于瓦楞纸板的粘合。 |

| This research aimed to synthesize a modified dextrin adhesive (MDA) with good water resistance and high fluidity for packaging application. The MDA was prepared with dextrin borax and trimethylol melamine (TMM) as raw materials by cross-linking polymerization. The five performance indicators including water resistance, drying rate, initial adhesion, solid content and viscosity of MDA were investigated by changing variables such as the cross-linking temperature, the ratio of TMM, dextrin and borax separately. The TMM improved the water resistance and adhesive strength when the MDA consisted of 0.8% borax and 16% TMM at the cross-linking temperature of 90 ℃, which showed water resistance was up to 123 h. The cross-linking between TMM and dextrin, as well as the structure of MDA was confirmed by FT-IR. The water resistance and viscosity of MDA was improved by crosslinking with TMM and the MDA can be used for corrugated board bonding. |
