Abstract
A technology and an equipment for manufacturing of sub-linear polyphenylene sulfide fiber belong to the research and development field of manufacturing technology and equipment of sub-linear polyphenylene sulfide fiber. Using injection-grade polyphenylene sulfide resin as the raw production material, the present invention, with solid polymerization, obtains excellent silk-forming property by uniformly distributing the molecular weight of molten raw-material bodies and bettering the flowability. The equipment of the present invention adopts a common spinning fiber production line, wherein the back part of a material feed hopper has a solid polymerizer, the front and rear parts of which respectively have a material inlet screw and a material outlet screw for controlling the amount of feeding and discharging material. The method of the present invention can be easily implemented; the object of producing sub-linear fiber with raw material of injection-grade resin can be realized just by slightly modifying a common spinning production line and controlling the polymerization temperature and pressure in production. The method solves the fiber production vacancy of the prior art and expands the raw material source for polyphenylene sulfide fiber production, and therefore being an ideal method for production of sub-linear polyphenylene sulfide fiber.
Description
Technical field
The invention belongs to the manufacturing technology of sub-patterned polyphenylene sulfide fibre and the research and development field of equipment.
Background technology
Polyphenylene sulfide fibre is by the polyphenylene sulfide manufacturing, and polyphenylene sulfide is divided into high linear and low linear according to molecular structure, be called fibre-grade on the market with two kinds of injection grade.Generally can make polyphenylene sulfide fibre, and that the polyphenylene sulfide of injection grade can only be used for is plastic injection-moulded, can not makes polyphenylene sulfide fibre with the fiber-grade polyphenyl thioether resin.Because the molecular weight distribution inequality of injection grade polyphenylene sulfide melt is mobile bad unstable again, so be not easy into silk.Therefore the injection grade resin can not producd fibers.Because fibre-grade is different with the injection grade resin property different with manufacturing cost, so their price variance is very big, fibre resin is the twice of injection grade resin.Sub-patterned polyphenylene sulfide fibre manufacturing technology is exactly to adopt the polyphenylene sulfide of injection grade to make polyphenylene sulfide fibre.To reduce production costs, widen and produce the polyphenylene sulfide fibre raw material sources.
Summary of the invention
The purpose of this invention is to provide a kind of skill that adopts the injection grade polyphenylene sulfide to make fiber
Art and equipment are with the breakthrough that realizes that the injection grade raw material can be made fiber.
The present invention is achieved by the following scheme
Earlier the polyphenylene sulfide resin fat raw material with injection grade carries out solid phase, behind solid phase, enters screw extruder, manifold is produced.
Its device structure is:
Have a solid-phase aggregator at the rear portion of spinning production line loading hopper.Between loading hopper and solid-phase aggregator, have feed worm.At the rear portion of solid-phase aggregator is spinning manifold.Between solid-phase aggregator and spinning manifold, have the discharging screw rod.Loading hopper, feed worm, solid-phase aggregator, discharging screw rod, spinning manifold interconnect by pipeline.
Its production method is:
Resin raw material enters solid-phase aggregator from loading hopper and carries out solid phase, and the temperature of solid phase is between 240～260 ℃, and temperature is remained on more than the polyphenylene sulfide softening temperature.Negative-pressure vacuum degree in the solid-phase aggregator is 400～500mmhg.Polymerization time is 4～5 hours.Feed worm on the equipment and discharging screw rod are to be used for controlling the amount of charging and the amount of discharging.The program of its production is: the solid phase fusion, to extrude, spray silk moulding integrated, the bucket that falls then, and boundling, drawing-off is curled, drying, typing is cut off, packing.Finish production process.
Key problem in technology of the present invention is to have solved the problem that injection grade molecular resin amount increases.Because more than softening point, so when extrusion molten, fusion is even, the good fluidity of melt, thus it is irregular to have overcome injection grade polyphenylene sulfide melt molecular weight distribution, and flowing instability is difficult for becoming the shortcoming of silk.The inventive method is simple, and is easy to implement, just common VD404 spinning production line transformed a little, grasps the temperature and pressure of solid phase in the production, can reach to adopt the injection grade resin raw material to produce the polyphenylene sulfide fibre effect.Realize the production of sub-patterned polyphenylene sulfide fibre.Solved the problem that the injection grade resin can not producd fibers.Widened the source of polyphenylene sulfide fibre raw materials for production.Be a kind of desirable sub-patterned polyphenylene sulfide fibre manufacturing technology and equipment.
