Description
Technical field
The present invention relates to cable material field, particularly relate to good poly-ethylene cable material of a kind of elasticity high flexibility and preparation method thereof.
Background technology
Communication, electric power are the development in the emphasis of nation-building, whichever place, and communication, power construction are always leading, so communication, electric utility development are very fast.The development of communication, electric utility, working in coordination of all respects is wanted in spontaneous combustion, wherein CABLE MATERIALS is exactly an aspect, general electric wire is coating expects mainly plastics casing rubber, as long as electric wire thermoplastics has polyvinyl chloride, polyethylene, polypropylene, fluoroplastics, penton and polymeric amide, wherein widely used is polyethylene and polyvinyl chloride.In China's polyvinyl chloride cable material development comparatively early, kind model is more, for the manufacture of wire cable insulating and the sheath of various temperature classification.Because density of pe is little, electrical property is excellent, be easy to forming process.Polyethylene is the large kind of one in thermoplastics, there is the features such as light weight, nontoxic, chemical resistance is excellent, but poly oxygen index is very low, belong to inflammable material, polyethylene can produce serious melting drippage behavior when burning, this brings very large difficulty to flame retardant resistance, except inflammable, poly volume specific resistance and surface resistivity are very high, this just makes it once bring electrostatic to be just difficult to eliminate in processing and use procedure, and two above shortcomings bring very large potential safety hazard and reduce use range to poly use.Red phosphorus is the efficient flame-retarding agent of the superpolymer such as plastics, rubber, resin and synthon, and red phosphorus itself is inflammable, badly influences the flame retardant effect of red phosphorus.Calcium carbonate filling modification high density polyethylene(HDPE), research emphasis comparatively early concentrates on and how to realize filling to greatest extent, reduce costs, although improve the rigidity of material, but intensity and the fracture toughness property of material is greatly reduced, and be not suitable for carrying high density polyethylene(HDPE) sheath material, the present invention adopts special process modified nano calcium carbonate to not only improve filler dispersion effect in the base and enhances the two cohesive strength, improve intensity and the toughness of polythene material, enhance bearing capacity greatly, mechanical property is improved greatly.
