Description
Technical field
The present invention relates to be used for the plastics of electric wire, belong to macromolecular material.
Background technology
The wire cable insulating material to the polyolefin insulation material transition, is because polyolefin has the advantages that electrical insulation properties is excellent, mechanical and physical performance is good by polyvinyl chloride at present.And polyolefin insulation is to crosslinkedization development.At present, the cable crosslinking technological mainly contains three kinds of modes, i.e. the warm water crosslinking method of silane grafting, peroxide chemical crosslink technique and high-energy electron beam irradiation cross-linking method.Change the space multistory network structure by the crosslinked electric wire high molecular polymer that makes by linear structure, thereby reach the purpose of material modification.Commonly used is that chemical crosslinking and silane connect the skill mode at present, and chemical crosslinking is when extrusion molding, and to the equipment requirements height, investment is big, and productivity effect is low, is only applicable to the mesohigh insulated power cable; The silane warm water crosslinking, not high to equipment requirements, processing technology is simple, but the degree of cross linking is difficult for improving; Cross-linking radiation then carries out at normal temperatures and pressures, do not need crosslinked medium, not only save the energy, and production efficiency height, the suitable material scope is wide, because the polymer that causes of absorbed radiation energy heats up and is no more than 70 ℃ usually, being added with the halogen-free polyolefin insulated layer of fire retardants such as hydrated alumina or magnesium hydroxide or sheath can be because of pyrolysis in cross-linking process, thereby is particularly suitable for processing flame retardant cable.General hydrated alumina of present domestic employing or magnesium hydroxide are made fire retardant, but in order to reach sufficient flame retardant effect, must sneak into enough inorganic combustion inhibitors, generally need 50%-60%, sneaking into of so a large amount of inorganic combustion inhibitors, must cause the physical property of packing material to descend, influence processing characteristics, the electric durability of material can be descended, dielectric loss rises, limited the application in high pressure (more than the 6kV) cable and most of communication cable, it is easy to study some technologies, and the cable that adapts to the radiation mode use just becomes the challenge problem of cable material industry with material.
Summary of the invention
