Abstract
A manufacturing technology of an HDPE skeleton material for a skeleton-type ribbon optical cable. The invention provides the manufacturing technology of the HDPE skeleton material for the skeleton-type ribbon optical cable, wherein the manufacturing technology is suitable for a requirement of rotating extrusion of an extrusion die head and includes following steps: 1) adding 0.3%-0.5% by weight of 4# white oil to 90-94% by weight of HDPE and 4-8% by weight of EVA performing a stirring process for 6-10 min; 2) adding 0.1%-0.5% by weight of a polypropylene nucleating agent NA-21 after the stirring operation in the step 1) is finished, performing a stirring process in a mixing machine for 8-12 min; and 3) feeding the material mixed in the step 2) into a 1:25 co-directional exhaust-type double-screw extruder and carrying out a mixing process with temperature in each zone being 190-200 DEG C and a rotational speed being controlled within 45-60 r/min and performing an extruding granulation process. According to the invention, white oil is added to HDPE (high-density polyethylene) and EVA (ethylene-vinyl acetate copolymer). The white oil can enhance flexibility and smoothness of a surface of a loose tube is enhanced, thereby being beneficial to cabling. The polypropylene nucleating agent can increase the speed of a crystallization process. The requirement of rotating extrusion of the extrusion die head can be satisfied.
Description
Technical field
The present invention relates to technical field of polymer materials, relate in particular to the production technique of the skeleton optical fiber ribbon cable material of a kind of HDPE.
Background technology
Along with the high speed development of opticfiber communication cause, the sharp increase of the quantity of information requirement, the optical cable that core number is large in the urgent need to a kind of external diameter is little.Slotted core fiber ribbon cable receives publicity due to plurality of advantages such as its density of optic fibre are high, construction install convenience.Slotted core cable overlays the fibre ribbon having made in spiral skeleton grooves and makes cable core, and with the wrapped skeleton of waterstop, skeleton adopts high-density polyethylene material (HDPE), then makes skeleton optical fiber ribbon cable at the additional protective material of cable core (PE material).Skeleton grooves becomes screw type rotary along optical cable, to guarantee to be positioned over optical fiber in groove with enough remaining length, has guaranteed tension, bending and the temperature profile of optical cable.Owing to adopting extrusion die rotation, make the seemingly fried dough twist of shape outside skeleton, processing is inconvenient, not easy-formation.
Summary of the invention
The present invention is directed to above problem, provide a kind of easy to process, the production technique of the skeleton optical fiber ribbon cable HDPE frame material that applicable extrusion die rotary extrusion requires.
Technical scheme of the present invention is: comprise the following steps:
1), in the HDPE of 90 ~ 94% weight ratios and the EVA of 4 ~ 8% weight ratios, add the 4# white oil of 3 ‰～5 ‰ weight ratios, stir 6 ~ 10 minutes;
2), 1) after step stirs and to finish, add the polypropylene nucleater NA-21 of 1 ‰～1.5 ‰ weight ratios, in mixer, stir 8 ~ 12 minutes;
3), by 2) material that mixes in step puts into 1:25 and carries out in vented twin-screw extruder in the same way mixingly, each district's temperature is 190～200 ℃, rotating speed is controlled at 45～60r/min, extruding pelletization.
The flow rate of described HDPE is less than 2g/10min.
The present invention is at HDPE(high density polyethylene(HDPE)) and EVA(ethylene-vinyl acetate copolymer) in increase white oil, white oil can increase flexibility, has improved its surperficial slickness, is beneficial to stranding; Polypropylene nucleater can accelerate crystallization, adapts to the needs of extrusion die rotary extrusion.
