Abstract
The invention discloses a fine-diameter stretching combined spinneret orifice which is composed of a plurality of fine-diameter spinneret orifices arranged on a spinneret plate and distributed in conically radial mode, wherein conical inlets are arranged at inlet ends of the fine-diameter spinneret orifices. The spinneret plate is provided with a conical guide inlet on the inlet sides of the spinneret orifices, and the conical inlets of the fine-diameter spinneret orifices are connected with the guide inlet. Fluid with containing ultra-high molecular weight polyethylene forms fluid monofilaments through the fine-diameter stretching combined spinneret orifice in combined stretching mode, and then high-strength and ultra-high molecular weight polyethylene monofilaments with the diameter to be equal to or larger than 0.07mm and the breaking strength to be equal to or larger than 1.6 GMa are obtained through post-processing procedures.
Description
Technical field
The present invention relates to the preparation of high-strength ultra-high molecular weight polyethylene monofilaments, relate in particular to spinneret orifice.
Background technology
Publication number is the preparation method that the Chinese invention patent of CN101886298A discloses a kind of ultra-high molecular weight polyethylene monofilaments.In patent documentation, having described and having adopted weight average molecular weight is that 100～7,000,000 polyethylene powders is mixed with the spinning solution of 10～25wt% through the white oil dissolving, it is the circular spinneret orifice ejection of 5.5～8mm at 250～330 ℃ of via hole diameters, through subzero 10 ℃ to subzero 1 ℃ of coagulating bath cooling, then through extraction, drying, carry out the hot-stretch of 2～4 grades at the temperature of 100～150 ℃, 30～50 times of total draw ratios make ultra-high molecular weight polyethylene monofilaments.Its spinneret orifice that adopts is single circular spinneret orifice, and the performance of stretched monofilament is still slightly inadequate.
Summary of the invention
Technical problem to be solved by this invention just is to provide a kind of thin footpath stretching combination type spinneret orifice for preparing high-strength ultra-high molecular weight polyethylene monofilaments, and the polyethylene monofilament of producing has good TENSILE STRENGTH and fracture strength.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of thin footpath stretching combination type spinneret orifice, it is characterized in that: the thin footpath spinneret orifice by the constant aperture of being located at several the tapered radial distributions on spinnerets forms, and the entrance point of described thin footpath spinneret orifice is provided with the taper import.
Preferably, described spinnerets is provided with the guiding import of taper at the spinneret orifice inlet side, and the taper import of thin footpath spinneret orifice is joined with the guiding import.
Preferably, the ratio 1.01～20:1 of the sectional area of the import sectional area of described taper import and thin footpath spinneret orifice.
Preferably, described thin footpath spinneret orifice the aperture be 0.5～2mm, draw ratio 5～15:1.
Preferably, the spacer holes distance at the adjacent thin footpath of the spinneret orifice port of export, thin footpath spinneret orifice is 0～35% of thin footpath spinneret orifice diameter.
Preferably, the merging ratio of the tension type spinneret orifice of described merging is 3～169:1, and the tension type spinneret orifice draw ratio of described merging is 1.01～30.
The present invention adopts thin footpath stretching combination type spinneret orifice will contain the ultra-high molecular weight polyethylene fluid and forms the fluid monofilament through merging to stretch.And then through the fluid filament stretch, through the cooling frozen glue monofilament of making.Then make the high-strength ultra-high molecular weight polyethylene monofilaments of diameter 〉=0.07mm, fracture strength 〉=1.6GMa through predraft, extraction, dried bath, super times hot-stretch postprocessing working procedures.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is thin footpath stretching combination type spinneret pore structure schematic diagram;
Fig. 2 is thin footpath stretching combination type spinneret orifice port of export structural representation.
The specific embodiment
A plurality of thin footpath stretching combination type spinneret orifices can be arranged on spinnerets, and as shown in Figure 1, each thin footpath stretching combination type spinneret orifice forms by the thin footpath spinneret orifice 2 in the constant aperture of several tapered radial distributions.The aperture of thin footpath spinneret orifice 2 is 0.5～2mm, is preferably 1mm, and draw ratio 5～15:1 is preferably 10:1.The entrance point of thin footpath spinneret orifice 2 is provided with taper import 1.Ratio 1.01～the 20:1 of the sectional area of the import sectional area of taper import 1 and thin footpath spinneret orifice 2 is preferably 2:1.Spinnerets is provided with the guiding import 3 of taper at the spinneret orifice inlet side, the taper import 1 of thin footpath spinneret orifice 2 is joined with guiding import 3.
As shown in Figure 2, the spacer holes at thin adjacent thin footpath spinneret orifice of footpath spinneret orifice 2 ports of export is 0～35% of thin footpath spinneret orifice diameter apart from 4.The spinneret orifice that merges ratio for small scale can omit the guiding import 3 in spinneret orifice.
