Insulating material for washing machine motor copper wires and preparation method thereof

The invention discloses an insulating material for a copper wire of a motor of a washing machine. The insulating material is prepared from the following raw materials in parts by weight: 30-50 parts of PBT resin, 15-30 parts of siloxane prepolymer, 5-15 parts of glass fiber, 1-3 parts of catalyst, 3-5 parts of end-capping curing agent, 2-5 parts of silane coupling agent, 3-10 parts of nanoparticles, 20-35 parts of reactive diluent and 0.5-2 parts of initiator. The invention further discloses a preparation method of the insulating material for the copper wire of the washing machine motor. The insulating material has good insulating property, mechanical property, adhesive force, chemical corrosion resistance, heat resistance and corona resistance and stable performance, and the service lifeis greatly prolonged when the insulating material is used as an insulating layer. 本发明公开了一种洗衣机电机铜线用绝缘材料，其制备原料按重量份数包括以下组分：PBT树脂30～50份、硅氧烷预聚物15～30份、玻璃纤维5～15份、催化剂1～3份、封端固化剂3～5份、硅烷偶联剂2～5份、纳米粒子3～10份、活性稀释剂20～35份、引发剂0.5～2份。本发明还公开了一种洗
