Description
Technical field
The invention belongs to polypropylene fibre production technical fields, and in particular to a kind of red pigment disperse sufficient polypropylene original mixing and
Preparation method.
Background technique
Polypropylene fibre is acrylic resin through polypropylene fibre made of melt spinning, light, the straight smooth, intensity with quality
High, non-hygroscopic, the features such as acid-fast alkali-proof is strong.But the dyeability of polypropylene fibre is poor, presently mainly by pp material
Pigment spinning is added and prepares colored polypropylene fibre.If but color is dispersed insufficient in pp material, not only produces polypropylene fibre
Add lustre to difference, and will affect the quality of polypropylene fibre.
Current art-recognized red pigment is not easy to disperse in pp material, and now the polypropylene original of common red pigment is mixed
Material formula are as follows: PP GRANULES 39.32% consolidates bright red 37.99%, Rushan wax 19.94%, electrostatic agent 1.33%, stearic acid forever
Calcium 1.33%, silicone powder 0.09%.Preparation method includes that above-mentioned raw materials are directly mixed dispersion or pigment is made pre- point
Granular media participates in dispersion；First method has the fecula of 3%-8%, and granulation is caused to be difficult to filter, and filament spinning component service life shortens
70%, waste silk amount is big, easily color difference out.Although dispersion effect can be improved in second method, but invest greatly, and generate water pollution
Problem, high production cost.Therefore, it is necessary to conduct a research for dispersion effect of the red pigment in polypropylene original mixing is improved.
Summary of the invention
For the problem that existing red pigment is not easy to disperse in polypropylene original mixing, polypropylene fibre is caused color difference occur, the present invention
A kind of red pigment of being designed to provide disperse sufficient polypropylene original mixing, compared with existing polypropylene original mixture recipes,
Red pigment dispersion effect gets a promotion, and polypropylene fibre quality and processing cost are also improved.
Another object of the present invention is to provide the preparation methods that the red pigment disperses sufficient polypropylene original mixing.
The present invention provides the following technical solution.
A kind of sufficient polypropylene original mixing of red pigment dispersion, is grouped as: polypropylene by each group of following mass percent
Powder >=48%, red pigment 27~30%, polyethylene wax >=17%, electrostatic agent 0.95~1%, 0.05~0.1% and of silicone powder
Glidant 2.5~3%, the sum of mass percent of above-mentioned each component are 100%, softening point >=120 DEG C of polyethylene wax
As of the invention preferred: the red pigment is to consolidate bright red forever.
As of the invention preferred: the polyethylene wax is BASF PE2.
As of the invention preferred: the glidant is zinc stearate.In the prior art using calcium stearate as poly- third
The release agent of alkene, inventor have found through overtesting, use zinc stearate as glidant, are granulated to dispersion, especially to spinning
Spinnability is significantly increased.
As of the invention preferred: it is grouped as by each group of following mass percent: MFI20 polypropylene powder 49.97%,
Consolidate bright red pigment 27.99%, BASF PE2 polyethylene wax 18.19%, zinc stearate 2.80%, electrostatic agent 0.98%, silicone forever
Powder 0.07%.
As of the invention preferred: polypropylene original mixing of the invention and existing polypropylene original mixing beauty's material formula phase
Than being improved in terms of three:
First, increase polyacrylic dosage, dispersion concentration of the relative reduction red pigment in polypropylene original mixing improves red
The dispersion adequacy of pigment.But the concentration of red pigment is too low to may cause the excessive energy beyond metering system of Masterbatch additional amount
Power, it is inconvenient.But the concentration of red pigment can not obtain the apparent effect for promoting dispersion when reducing few, therefore there are one
The catastrophe point of polypropylene powder dosage, is obviously improved dispersion effect.By being gathered by largely testing and analyzing to limit
Propylene and red pigment compare, when making red pigment content 27~30%, polypropylene powder >=48%.
Second, selecting melt flow index MFI is 20 polypropylene powder, substitutes the polypropylene that original MFI is 30
Pellet improves dispersibility.
Third, third select the polyethylene wax of softening point >=120 DEG C as dispersing agent.Inventors have found that using softening point
Polyethylene wax not less than 120 DEG C can make polyethylene wax keep solid-state without softening at the right time, in this way can be with
The jitter time for extending polypropylene original mixing is not less than 20min, promotes the fully dispersed of polypropylene original mixing；Simultaneously also by the later period
Curing time extended to 7~8 seconds by 2~3 seconds, makes optimal blowing opportunity be more easier to grasp, greatly promotes dispersion effect.
4th, at the same inventor by a large amount of the study found that in the formula range of the application, with polypropylene powder
The increase of dosage or the change of this single factor test of polyethylene wax dosage, this rush dispersion effect is gradually promoted, but is worked as
It when going to change simultaneously each factor as a whole with the formula of the application, is preferably formulated there are one, it may be assumed that MFI20's is poly-
Propylene powder 49.97wt%, consolidate bright red pigment 27.99wt%, BASF PE2 polyethylene wax 18.19wt%, zinc stearate forever
2.80wt%, electrostatic agent 0.98wt%, silicone powder 0.07wt%.When the use for changing a certain component such as polypropylene powder in the formula
Amount, such as increase by 1 percentage, dispersion effect, which is higher than, reduces 1 percentage, but the dispersibility of the two is below this Shen
It please obtained above-mentioned better formula.
Above-mentioned red pigment disperses the preparation method of sufficient polypropylene original mixing, comprising the following steps:
(1) each raw material is sequentially added in batch mixer, starts batch mixer, batch mixer is kept to slowly run mixing；
(2) it then increases batch mixer revolving speed to standard working speed to rotate, is sufficiently mixed material；
(3) batch mixer is reduced to the state that slowly runs to wait for that material cures again, material is released completely, obtained described red
Pigment disperses sufficient polypropylene original mixing.
As the preferred of the method for the present invention, the revolving speed to slowly run in step (1) is 150~200 revs/min, runing time 5
~7 minutes.
As the preferred of the method for the present invention, step (2) Plays revolving speed is 1500~1800 turns/min, rotation time 15
~18 minutes.
Polypropylene original mixing of the invention segmentation mix on the basis of above-mentioned formula, this is because inventor is after study
It was found that each component of former mixing is mixed under lower-speed state first, inhibit the generation of heat in mixed process and is thus caused
Temperature increase, can will not melt as far as possible in the form of guarantee section component such as polyethylene wax keep original in this way, provide
Each component sufficient mixing machine meeting, then high-speed rotation mixing again, promotes mixing full and uniform dispersion.
Beneficial effects of the present invention are as follows:
Polypropylene original mixing of the invention is prepared through special formulation and technique, and bright red dispersion is abundant admittedly forever, substantially without fecula
It generates, and extends high speed mixing time and curing time, improve the service life of filament spinning component, the color of gained polypropylene fibre is good, base
This no color differnece occurs, and waste silk amount is also greatly decreased.
