摘　　要：通过加入聚醚改性聚硅氧烷,改性聚酰胺酰亚胺漆,制备了自润滑聚酰胺酰亚胺漆。研究了聚醚改性聚硅氧烷对PAI漆的粘度、固含量性能及成膜性能的影响,研究了聚醚改性聚硅氧烷对聚酰胺酰亚胺漆膜的拉伸性能、表面静摩擦力性能影响。通过漆包工艺,在漆包线外层涂敷2 um的自润滑聚酰胺酰亚胺漆膜,分析漆包线的力学性能、电学、热学性能。结果发现:聚醚改性聚硅氧烷的加入,降低了漆包线漆膜表面的静摩擦力,同时不影响PAI漆的粘度、固含量,不影响漆膜的拉伸性能;涂在漆包线表面,漆包线表面的静摩降低80%以上,漆包线能保持优良电学、力学、热学性能。Self-lubricating Polyamide-imide(PAI)enamel was prepared by adding Polyether Modified Polysiloxane into PAI enamel.We studied the effects of Polyether Modified Polysiloxane on the viscosity,solid content,and film-forming properties of PAI enamel,and investigated the effects of Polyether Modified Polysiloxane on the tensile and surface static friction properties of PAI films.By using the enameling process,a 2 um self-lubricating PAI film is applied on the outer layer of the enameled wire,and the mechanical,electrical,and thermal properties of the enameled wire were analyzed.It was found that the addition of Polyether Modified Polysiloxane reduced the static friction force on the surface of the enameled film.At the same time,it did not affect the viscosity and solid content of PAI enamel,nor did it affect the tensile performance of the enameled film.When applied to the surface of enameled wire,the static friction on the surface of the wire was reduced by more than 80%,and the wire could maintain excellent electrical,mechanical,and thermal properties.
