Technical field
The present invention relates to the technical field of cable jacket, particularly relate to a kind of cable jacket material and preparation method thereof.
Background technology
MDPE and medium-density polyethylene plastics are main raw material(s)s of cable jacket production and application, and usage quantity is comparatively large, but its density is large, and during production, consumption is large, and cost is high; And intensity comparatively engineering plastics is low.Along with the atrophy increasingly of hydrocarbon resources, being expected to rise for a long time of World oil price, the unit cost of PE material will be more and more higher.
And the preparation of cellular plastic is current macromolecular material development one of field the most rapidly, so-called cellular plastic refers to that bubble diameter is at 1 ~ 10 μm, and cell density is 10
9~ 10
15individual/cm
3novel foamed plastic.When in porous plastics, the size of abscess is less than the crackle of abscess material inside, the existence of abscess can not reduce the mechanical property of material; And the existence of micropore will make the unborn crack tip passivation of material, be conducive to stoping the expansion of crackle under stress, thus the performance of material is improved.Compared with the plastics do not foamed, cellular plastic, except density can reduce by 5% ~ 95%, also has the following advantages: shock strength is high, toughness is high, specific rigidity is high, fatigue lifetime is long, specific inductivity is low, thermal conduction factor is low.The predicament that optical cable material cost of greatly can alleviating use cellular plastic strengthens day by day.But poromerics preparation at present, great majority use extrudes filling high pressure gas form, is that Air Bubble Size or the control of number of bubbles are all very unstable, becomes a difficult problem of this technology large-scale application of puzzlement.The present invention solely wards off and lifts up footpath, solves this difficult problem by the mode novelty of polymer modification, lays a good foundation to following extensive commercialization.
