Problems solved by technology

[0002] At present, the existing production methods of polyolefin crosslinking are generally the following two types: (1) electron accelerator or cobalt source for irradiation crosslinking to obtain high temperature resistance and flame retardancy (2) silane crosslinking using water Or steam cooking for cross-linking, however, the above-mentioned cross-linking method requires an electron accelerator or a cobalt source to irradiate the wire core for cross-linking separately, and silane cross-linking requires stricter extrusion equipment during the extrusion process, and the process is more complicated , longer construction period and higher cost

Abstract

The invention relates to the technical field of insulating materials, in particular to an ultraviolet irradiation cross-linked polyethylene insulating material. The insulating material is mainly prepared from, by weight, 80-120 parts of polyethylene resin, 1-2 parts of diphenyl ketone, 0.1-0.5 part of dimethoxybenzoin, 0.5-1.5 parts of triallyl isocyanurate, 0.2-0.7 part of trimethylolpropane triacrylate, 0.1-0.3 part of an ultraviolet absorbent, 0.5-1.5 parts of an antioxidant and 0.5-1 part of a lubricant. The insulating material is low in extruding equipment requirement and wide in extruding temperature range, easiness in operation, low cost, high cross-linking speed and time saving are realized, and indexes are superior to national standard requirements.
