Embodiment 1-6
[0030] Embodiment 1-6 Preparation method of special electromagnetic wire
[0031] The special electromagnetic wire includes a wire and an insulating layer. Embodiments 1-6 are respectively a preparation method of a special electromagnetic wire. The raw materials of the insulating layer of the special electromagnetic wire are shown in Table 1, and the process parameters are shown in Table 2. The preparation method is as follows: Follow these steps:
[0032] 1) Paying off
[0033] After the wire is formed to meet the requirements of the wire, the wire is released;
[0034] 2) Immersion oil
[0035] Place the wires after setting off in the oil immersion device for oil immersion. The oil used is a high temperature resistant mineral synthetic oil with a temperature resistance rating of 200-300°C and a density of 0.986-1.033g / cm 3 , the viscosity is 100-200mPa.s, the oil immersion temperature is 20-60℃, the time is 2-10s, and the sulfur content in the oil is 100-500ppm;
