Embodiment
In conjunction with the preferred embodiments the present invention is done further detailed explanation now.
The present invention proposes a kind of optical cable and uses sheath material, and it comprises following component, is by weight percentage:
Polyolefin base material 85%～95%,
Carbon black 2.35%～2.85%,
Inhibitor 0.5%～1%,
Auxiliary agent 0.8%～1%.
Polyolefin base material comprises PE base-material and properties-correcting agent among the present invention; Said Vilaterm base-material is formulated by high density polyethylene(HDPE), linear low density polyethylene or new LDPE (film grade); Said properties-correcting agent is EVA properties-correcting agent; Wherein the weight percent of Vilaterm base-material is 85%～90%, and the weight percent of EVA properties-correcting agent is 5%～10%.
The PE base-material also can be for by high density polyethylene(HDPE) and linear low density polyethylene or the formulated medium-density polyethylene of new LDPE (film grade), and said properties-correcting agent also can be CPE properties-correcting agent.
In this polyolefin base material, add a spot of EVA or CPE properties-correcting agent, can increase the toughness of sheath material.
Add carbon black in the sheath material, carbon black is as UV light absorber, prevents that ultraviolet from causing the degraded of polymkeric substance aging to the destruction of sub polyethylene subchain.In sheath material of the present invention, should add average particle size particle size is 20 nanometers, and content is that 2.60 ± 0.25% carbon black is as UV light absorber.Carbon black is necessary homodisperse in sheath material, need process black master in advance usually, is blended into it in the base-material and goes.
Among the present invention, inhibitor comprises main anti-oxidant and collaborative inhibitor, and wherein main anti-oxidant is 1010 phenol antioxidant, and its weight percent is 0.5%～0.8%.Collaborative inhibitor is a Tyox B, and its weight percent is 0.2%～0.5%.
In the present invention, said auxiliary agent comprises rheological agent, lubricant, plastics brightening agent and tenderizer, and its weight percent is respectively rheological agent 0.8%～1.2%, lubricant 0.5%～1%, plastics brightening agent 0.5%～1%, tenderizer 0.8%～1.2%.In sheath material, add different types of processing aid and can very big influence all be arranged to the processing characteristics of sheath material and even to improving the sheath performance.
Functions such as that auxiliary agent has is lubricated, surface-treated, melt viscosity adjusting, extremely important in cable jacket.
Wherein rheological agent is fluorine-containing rheological agent, and for example by the processing aid PPA of Minnesota Mining and Manufacturing Company's exploitation, it has effects such as the polyolefinic rheological property of improvement, melt viscosity adjusting, surface-treated.PPA is a kind of superfine particulate, in plastic body, has splendid sliding, can adopt polythene PE base-material and PPA powder to process master batch in the time of processing, is added in the base-material and goes.The effect of fluorine-containing rheological agent is following: (a) fluorine-containing rheological agent can migrate to head/melt interface and forms one deck book film, thereby reduces extrusion pressure as the lubricant of head; (b) at a certain temperature; The shearing rate value that the PE that adds PPA begins to take place continuous melt fracture begins to take place the shearing rate value of continuous melt fracture far above the PE that does not add PPA; Thereby can eliminate the phenomenon of melt fracture effectively, and reduce melt temperature, improve extrusion efficiency; Shark skin spot appears in the jacket surface of (c) avoiding extruding, and makes the surface bright more smooth.
To certain polymkeric substance and processing conditions, the content of PPA has an optimum value, and content is excessive not only to increase the extrusion performance that production cost also can influence sheath, and optical cable should be less than 1% with PPA content in the sheath material usually.
Lubricant is the PE wax lubricant, superpolymer after fusion, have higher viscosity usually, in the course of processing; When the fused superpolymer passes through spiral shell thorax and mold runner in extrusion; Polymer melt must produce friction with the processor surface, and some friction is very disadvantageous to the processing of polymkeric substance, and these frictions reduce fluidity of molten; Serious friction simultaneously can make jacket surface become coarse, lacks gloss or flow liner occurs.Therefore, needing to add to improve oilness, to reduce friction, reduce the interface adhesion property is purpose auxiliary agent, i.e. lubricant.Lubricant can also play effects such as fusion promotor, anti, antistatic agent and slipping agent except improving flowability.
Lubricant can mainly be divided into two kinds of external lubricant and internal lubricants: the effect of external lubricant mainly is the friction that improves the hot metal surface of polymer melt and processing units; It and polymer phase capacitive are relatively poor; Easily in the melt toward external migration, so can form lubricated thin layer at the interface of plastic melt and metal; Internal lubricant and polymkeric substance have good consistency, and it plays the effect that reduces force of cohesion between polymer molecule in polymkeric substance inside, thereby improve the living heat of internal friction of plastic melt and the flowability of melt.
External lubricant commonly used is Triple Pressed Stearic Acid and its esters, and internal lubricant is low-molecular-weight polymkeric substance.The lubricant that polyolefins is commonly used has erucicamide, high boiling point paraffin, the right wax of crystallite, PE wax etc.Adopting the PE wax lubricant in the present invention, is because it and PE base-material homogeneity have better consistency.
The plastics brightening agent adopts the modification amide waxe; It has good inside and outside lubricity and surface-brightening property; Good mutual fusibleness and non-stick property can improve the vividness and the luminance brightness of sheath material, have HMP and low viscous peculiar property and good transport property in molten mass.
Tenderizer is A6006, and A6006 is exclusively used in and adds the PE product, can increase the snappiness of PE, rebound resilience property and can increase the winter hardiness of PE, subduing property.
