摘　　要：本文对发电机定子冲片底涂层和绝缘涂层进行了扼要的介绍,对三种不同水溶性漆进行了交叉组合试验,研究了漆膜外观、厚度、耐溶剂性、附着力和绝缘电阻等方面的影响,还研究了不同底涂层冲片涂覆绝缘漆后的耐高温、耐腐蚀性能以及冲片断面的覆盖率。结果表明,在上述各方面底涂层对绝缘涂层都有影响,在实际使用过程中需要考虑冲片底涂层与绝缘涂层的兼容性问题。本文为设计和工艺人员选择冲片和涂漆材料提供了参考依据。This paper presents a brief introduction of the bottom coating and insulating coating ofgenerator stator lamination. Combined tests are performed to find out the influences in coatingfilm appearance, thickness, solvent endurance, adhesiveness and insulation resistance. Also, hightemperature resistance, anti-erosion and covering rate of lamination intersection of insulatingcoating with different bottom coatings are studied. The results show that bottom coating hasinfluence on insulating coatings, and compatibility should be considered in actual application. Thepaper can provide reference for design and process engineers to select laminations and coatingmaterials.
