Description
Technical field
The present invention relates to polymeric material field, particularly a kind of modified poly ethylene CABLE MATERIALS that is applicable to extruding and preparation method thereof.
Background technology
Insulating material for cable general requirement must have that good resistance to long term heat ageing performance, resistance to irradiation, electric property are stable, flame retardant properties and the excellent feature of insulating property.
Polyethylene (PE) is a kind of thermoplastic resin that ethene makes through polymerization.Industrial, also comprise the multipolymer of ethene and a small amount of alpha-olefin.Polyethylene odorless, nontoxic, feel ceraceous, has good resistance to low temperature, and chemical stability is good, the erosion of the most of soda acids of ability.Under normal temperature, be insoluble to common solvent, water-absorbent is little, and electrical insulation capability is good.High density polyethylene(HDPE), be commonly called as low pressure polyethylene, compare with LDPE and LLDPE, have higher heatproof, oil-proofness, resistance to vapour permeability and environmental stress crack resistance, in addition electrical insulating property and shock resistance and cold tolerance are fine, are mainly used in the fields such as blowing, injection moulding.Generally manufacturing electric wire insulating material of polyethylene, is all after polyethylene starting material and the mixing of various auxiliary agent, by Bitruder extruding pelletization, to be prepared into.The weak point such as there will be discharging unstable to disconnect in the course of processing, surface is crude, easily puncture, linear speed is slow, affects quality product and production rate.
