摘要
以特种支化醇醚芳酯胺改性某缩水甘油醚自制增韧剂,以自有专利合成环氧改性脂环胺固化剂,然后以双酚A型环氧树脂、双酚F型环氧树脂、稀释剂、玻璃纤维、触变剂、功能助剂、酚醛聚酰胺和自制的特种增韧剂及脂环胺固化剂等为原料制备了风电叶片二次合模用腹板粘接结构胶,研究了其制备工艺和流变黏度、放热峰和开放时间、拉伸强度、冲击强度、玻璃化转变温度、剪切强度和剪切疲劳等指标性能,结果表明:本研究制备的快速结构胶,具备40min以上操作时间和优化的快速定位时间,其余性能参数均满足风电级设计需求。
A self-made toughener from glycidyl ether modified by aryliesteric diamine with special alcohol-ether-branched,and a self-patented curing agent from cycloaliphatic diamine modified by epoxide were synthesized. Then bisphenol-A epoxy resin, bisphenol-F epoxy resin,diluent,glass fiber,hixotropic agent,functional additive,phenolic polyamide with self-made special toughener and modified alicyclic polyamine were prepared a structural adhesive. The adhesive is used for bonding stiffener’s webs of wind turbine blade by twice molding bonding.The preparating technology,rheological viscosity,exothermic peak with open time,tensile strength,impact strength,glass transition temperature,shear strength and shear fatigue properties were studied on.The results shows, that a new type structural adhesive was developed and prepared,holding fast operatable time still more than 40 minutes, and relatively optimized positioning time,as well as other performances parameters for meeting the wind power level design requirements.
