摘　　要：本研究对风电电机槽口用多功能灌封胶进行了配方研究和工艺优化。通过筛选,选取增韧环氧树脂作为胶的主要成分,使用柔性固化剂,配合活性稀释剂,以球型氧化铝和针状硅灰石为填料,制得可室温固化的风电电机槽口灌封用环氧胶,并与进口的有机硅灌封胶进行了性能对比测试。结果表明:制得的环氧灌封胶操作时间合理,黏度适中,其工艺性能和技术指标均达到使用要求,且具有价廉的优势。The formula and technology of multi-functional pouring sealant for wind turbine notch were optimized. A pouring sealant, which can be cured at room temperature, was prepared by using toughened epoxy resin as the main resin, spherical alumina and needle wollastonite as fillers, and adding flexible curing agent and reactive diluent. The properties of the prepared pouring sealant and the imported pouring sealant were tested and compared. The results show that the pouring sealant has applicable operation time, moderate viscosity, and low price, and its processing property and technical index can meet the requirement.
