摘　　要：采用高沸点新型活性交联单体及引发阻聚体系研制出一种电机散嵌绕组专用改性聚酯亚胺浸渍树脂。该树脂不含有苯乙烯、乙烯基甲苯,热稳定性好,能低温快速固化,固化挥发份极低,是一种新型环保无溶剂树脂。树脂固化后具有优异的电气及力学性能。制作了电机绕组通电加热模拟试验装置,电机绕组模拟通电加热工艺,对比试验结果表明:通电加热工艺比普通浸渍工艺挂漆质量高,改性聚酯亚胺树脂比传统树脂更适用于通电加热工艺。A modified polyester-imide impregnating resin for the random winding of motor was prepared using novel high boiling point reactive crosslinking monomer and initiated polymerization inhibition system. The resin is a novel environmental-friendly solvent-free resin without styrene and vinyl toluene; it has good thermal properties and low volatile content, and can cure rapidly under low temperature. The cured resin has excellent electrical and mechanical properties. The ohmic heating device for the random winding was prepared, and the ohmic heating process was simulated. The results show that the mass of varnish covered on winding treated by ohmic heating process is higher than that by common impregnating process. Ohmic heating process is more suitable for modified polyester-imide resin than conventional polyester resin.
