摘　　要：生物基胶黏剂具有环境友好、可再生等特性,具有广阔的应用前景。对生物油淀粉胶黏剂进行差热分析,研究了其固化过程中的热行为、固化反应动力学和固化工艺,为高效地优化、预测和控制其胶接工艺条件提供基础数据支撑;对比采用复合固化剂与单一固化剂的胶黏剂热行为,发现复合固化反应热更大,固化特征温度更低,表明复合固化剂体系固化更充分;不同生物油加入量对胶黏剂的热行为研究表明,随生物油加入量增加,固化反应放热量增加,但固化特征温度逐渐降低,进一步表明生物油有促进胶黏剂固化的作用。Bio-based adhesives have environmentally friendly,recyclable properties and have broad application prospects.Hence,the thermal behavior,curing kinetics and curing technology of bio-oil starch adhesive were studied by Differential Thermal Analysis(DTA)to provide the data foundation for efficient optimization,forecast and control of bonding technology.Compare to the thermal behavior of single curing agent,that of bio-oil starch adhesive by the composite curing agent had greater heat of curing reaction and lower curing temperature,which indicated that the curing effect of the composite curing agent was better than the single curing agent.With the increase of bio-oil dosage,the curing temperature of bio-oil starch adhesive became lower and the heat of curing reaction became larger,illustrating that bio-oil played a positive role in the curing of starch adhesive.
