Example Embodiment
[0012] Example 1
[0013] Weigh 100kg of refined naphthalene and 600kg of tetrahydrofuran, set aside. Nitrogen was introduced into the self-made reaction kettle. After stabilization, the prepared tetrahydrofuran was added. Then, the stirrer was turned on to start stirring. At the same time, 100 kg of refined naphthalene was added, and the naphthalene was completely dissolved by stirring. Then turn on the cooling device, make 10kg of sodium metal into small pieces and gradually add it. After all the sodium metal is added, control the temperature to react at 10°C for 2 hours. After the reaction was completed, the stirring was stopped, the temperature was slowly returned to normal temperature, and the material was discharged. The above-mentioned polytetrafluoroethylene surface treatment solution was evenly sprayed on the surface of the polytetrafluoroethylene film, and the surface treatment time was about 10s. Then the film was pulled, soaked for 1min through a washing tank equi...

[0014] Example 2
[0015] Weigh 100kg of refined naphthalene and 800kg of tetrahydrofuran, set aside. Nitrogen was introduced into the self-made reaction kettle. After stabilization, the prepared tetrahydrofuran was added. Then, the stirrer was turned on to start stirring. At the same time, 100 kg of refined naphthalene was added, and the naphthalene was completely dissolved by stirring. Then turn on the cooling device, make 15kg of sodium metal into small pieces and gradually add it. After all the sodium metal is added, control the temperature to react at 15°C for 1 hour. After the reaction was completed, the stirring was stopped, the temperature was slowly returned to normal temperature, and the material was discharged. The above-mentioned polytetrafluoroethylene surface treatment solution was evenly sprayed on the surface of the polytetrafluoroethylene film, and the surface treatment time was about 15s. Then the film was pulled, soaked in a washing tank equipped with ethan...

[0016] Example 3
[0017] Weigh 100kg of refined naphthalene and 650kg of tetrahydrofuran, set aside. Nitrogen was introduced into the reaction kettle, after stabilization, the prepared tetrahydrofuran was added, and then the stirrer was turned on to start stirring, and 100 kg of refined naphthalene was added simultaneously, and the naphthalene was completely dissolved by stirring. Then turn on the cooling device, make 13kg of sodium metal into small pieces and gradually add it. After all the sodium metal is added, control the temperature to react at 10°C for 2 hours. After the reaction was completed, the stirring was stopped, the temperature was slowly returned to normal temperature, and the material was discharged. The above-mentioned polytetrafluoroethylene surface treatment liquid was evenly sprayed on the surface of the polytetrafluoroethylene film, and the surface treatment time was about 10s. Then the film was pulled, soaked in a washing tank containing methanol for 2m...
