电动汽车电机的耐变速箱油无卤阻燃槽绝缘材料及其应用
摘要：
本发明公开了一种电动汽车电机的耐变速箱油无卤阻燃槽绝缘材料，包括依次层叠设置的第一编织玻璃布、聚苯硫醚薄膜和第二编织玻璃布，第一编织玻璃布和聚苯硫醚薄膜之间和聚苯硫醚薄膜和第二编织玻璃布之间通过复合胶粘结，复合胶包括PU胶、环氧胶和无卤阻燃剂，PU胶、无卤阻燃剂与环氧胶的质量比为8~10:0.5~2：1；环氧胶包括改性环氧树脂和环氧树脂固化剂，其质量比为4~8:1；及其在电机绕制线圈和电器中的应用。通过采用特定质量比例的PU胶、环氧胶和无卤阻燃剂形成的复合胶，环氧胶包括改性环氧树脂和环氧树脂固化剂，制得的耐热达到F、H级的槽绝缘材料具有交联密度高、耐变速箱油、良好的阻燃性和高机械强度等优点。
摘要（英）：

The invention discloses a gearbox-oil-resistant and halogen-free flame-retardant groove insulating material of an electric vehicle motor. The groove insulating material comprises first weaving glass cloth, a polyphenylene sulfide thin film and second weaving glass cloth which are arranged in a stacked manner in sequence; the first weaving glass cloth and the polyphenylene sulfide thin film, and the polyphenylene sulfide thin film and the second weaving glass cloth are bonded through composite adhesive; the composite adhesive comprises PU adhesive, epoxy adhesive and a halogen-free flame-retardant agent at the mass ratio of (8-10) to (0.5-2) to 1; the epoxy adhesive comprises modified epoxy resin and an epoxy resin curing agent at the mass ratio of (4-8) to 1; and an application of the groove insulating material in a motor winding coil and an electric appliance is disclosed. The composite adhesive is formed from the PU adhesive, epoxy adhesive and the halogen-free flame-retardant agentat the specific mass proportion; and the epoxy adhesive comprises modified epoxy resin and the epoxy resin curing agent, so that the prepared groove insulating material with the heat resistance levelof F and H has the advantages of high crosslinking density, gearbox oil resistance, high flame retardancy, high mechanical strength and the like.
