Embodiment 1
[0026] An oil-proof and waterproof insulating cable material, the preparation method of which is as follows: 40% chlorinated polyethylene, 3% PE wax, 40% nanometer talcum powder, 3% tetrakis[β-(3,5- Di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester, 7% triallyl isocyanurate, and 7% dicumyl peroxide were put into the internal mixer in turn, and the mixing time was 10 minutes. The extruder reaches 125°C, and the material is discharged; the mixture is added to the twin-screw extruder for extrusion, and then granulated.
[0027] The performance data of the oil-proof and waterproof insulating cable material prepared by the embodiment 1 of table 1
[0028]
Embodiment 2
