Embodiment 1
[0044] This embodiment relates to an anti-scorch chemically cross-linked insulating material, which contains the following raw material components and parts by weight:
[0045]
[0046] According to the above-mentioned raw material ratio, the low-density polyethylene and dicumyl peroxide in the anti-scorch chemical cross-linked insulating material are mixed and extruded into the semi-finished material in the upper stage of a reciprocating single-screw extruder at 60-120 °C, and mixed The four temperature sections of the reciprocating single-screw extruder during the extrusion process are: feeding section 60-70°C, conveying section 100-105°C, melting section 100-105°C, head 100-105°C). The anti-oxidant 300, diphenylamine nitrite, zinc stearate in the scorch chemical cross-linked insulating material and the semi-finished material extruded from the upper stage are mixed in the lower stage through a single-screw extruder at 100-110°C. During the mixing process, the single-screw ...

[0049] This embodiment relates to an anti-scorch chemically cross-linked insulating material, which contains the following raw material components and parts by weight:
[0050]
[0051]
[0052] According to the above-mentioned raw material ratio, the low-density polyethylene, dicumyl peroxide and benzoyl peroxide in the anti-scorch chemical cross-linked insulating material are mixed and extruded in the upper stage of a reciprocating single-screw extruder at 60-120°C. The four temperature sections of the reciprocating single-screw extruder during the mixing and extrusion process are: feeding section 60-70°C, conveying section 100-105°C, melting section 100-105°C, head 100-105°C ℃, the antioxidant 1010, antioxidant 300, diphenylnitrosamine, polyethylene wax, polyamide and the semi-finished material extruded from the upper stage in the anti-scorch chemical cross-linked insulation material are passed through 100~ 110°C single-screw extruder for mixing. During the mixing pro...
