摘　　要：研究了在改性聚酯树脂中引入二苯基丙烷结构来提高其耐热性能,制成的耐热聚酯电磁线漆作底漆与聚酰胺酰亚胺电磁线漆配合使用,涂制的QZY/XY-200级复合漆包线热软化温度可以达到380℃,热冲击性能在漆包线拉伸10%、240℃、30 min条件下1 d不开裂,提高了特种电机的耐高温工作能力。This paper mainly studies the polyester resin with the diphenyl propane structure to improve its heat resistance. The softening temperature of so obtained QZY/XY-level 200 composite enameled wire can be achieved above 380 ℃, thermal shock performance is uncrazed in 1 D under the conditions of 240℃, with enameled wire drawing 10% during 30 min. The high temperature resistant ability of the special motor can be improved.
