Abstract
The invention provides a kind of manufacture method of polypropylene cooling colour batch.It is characterized in that molecular weight regulator and pre-dispersed good face (dying) material and acrylic resin in proportion blending push and make high dense masterbatch through screw rod.Its performance be better than lowering the temperature effect of masterbatch and colour batch the two and time spent.At spinning during polypropylene fibre, the polypropylene cooling colour batch that only needs 2%～4% usefulness method of the present invention of blend polypropylene weight resin to make.Not only can obtain fiber bright in colour.And can reduce by 20 ℃～60 ℃ of spinning temperatures.
Description
The technical field of the invention is a Process Technology of Polymer.
As everyone knows, in the manufacturing processed of polypropylene fibre, because the acrylic resin molecular weight ratio is bigger, up to about 200,000, in order to improve the method that viscous flow performance usually adopts the elevated temperature heat degraded, but after spinning temperature improves, the degraded of molecular weight is not well-proportioned, and it is more to produce lousiness, when especially the blend polypropylene colour batch carries out the original liquid coloring spinning in acrylic resin, because the auxiliary agents such as antiager face (dying) material in the acrylic resin are unable to undergo 300 ℃ high temperature, decomposition vapors away easily, loses due performance, makes spinning chamber's smog big, the look silk tarnishes, so when spinning polypropylene look silk, often in acrylic resin except adding colour batch, also to add the cooling masterbatch that contains di-t-butyl peroxide, in order to reach the molecular weight of regulating resin, reduce spinning temperature, improve viscous flow performance and spinning environment.But owing to add masterbatch twice, fibre strength is reduced, lousiness is more, and cost increases.
Purpose of the present invention in order to improve above-mentioned weak point, provides a kind of manufacture method that not only has the function of cooling masterbatch but also play the polypropylene cooling colour batch of color concentrate effect.With the polypropylene cooling colour batch that manufacture method of the present invention is produced, spinning temperature can reduce by 20 ℃～60 ℃, the polypropylene fibre lovely luster of spinning, and intensity is higher, and extension at break is less.Improved the spinning environment, reduced production cost, its performance is better than adding simultaneously cooling masterbatch and colour batch and the polypropylene fibre that spins.
Technology of the present invention is constructed as follows:
A certain amount of organo-peroxide, pre-dispersed good face (dying) material and very a spot of dispersion agent blending less than 2 microns are advanced in acrylic resin or the powder.Enter screw extruder after stirring.The melt of extruding promptly can be made into the polypropylene cooling colour batch through steps such as water-bath cooling, cut-outs, and its melting index scope restrains/10 fens 30～80.
(1) makes the method for polypropylene cooling colour batch with single-screw extrusion machine
Di-t-butyl peroxide is coated on the acrylic resin outside with 0.5%～3% addition in acrylic resin weight, add then with respect to 10%～30% pre-dispersed good face (dying) of acrylic resin weight and expect and 5%～10% low molecular polyethylene powder or the magnesium stearate that are equivalent to face (dying) material weight stirs, enter single-screw extrusion machine through hopper, extruding pelletization under 130 ℃～～230 ℃ temperature, the polypropylene cooling colour batch melting index of making were controlled at 30～80 grams/10 minutes.
(2) twin-screw extruder is made the method for polypropylene cooling colour batch
0.5%～3% di-t-butyl peroxide with respect to acrylic resin weight is coated on the acrylic resin outside, and adding after stirring with respect to 2%～8% low molecular weight polyethylene powder of acrylic resin weight or magnesium stearate is that a component is put into a hopper again; Put into another hopper with respect to 10%～30% pre-dispersed good face (dying) material of acrylic resin weight with respect to 2%～8% low molecular polyethylene powder or magnesium stearate of face (dying) material weight for another component, two kinds of components are controlled metering respectively, enter twin-screw extruder, extruding pelletization under 130 ℃～230 ℃ temperature is made polypropylene cooling colour batch melting index and was controlled at 30～80 grams/10 minutes.
Enforcement of the present invention provides by following example:
Example 1:
The magnesium stearates that add 68 gram di-t-butyl peroxides, 42 grams in 4 kilograms of/10 minutes the acrylic resins of melting index 9 gram are stirred, add again after 600 grams mix through the pigment thermally oxidized blacks less than 2 microns of pre-dispersed processing, enter single-screw extrusion machine through hopper, extruding pelletization under 130 ℃～230 ℃ temperature, the polypropylene black of making cooling masterbatch melting index is 41 grams/10 minutes.
Spinning behind the blending 90 gram cooling black masterbatch in 3 kilograms of acrylic resins, 180 ℃～270 ℃ of spinning temperatures, 500 meters/minute of winding speeds stretch 5.3 times.The fibre breakage intensity that obtains was 5.36 gram/dawn, extension at break 17.1%, fiber bright in colour.
Example 2:
With melting index 10 gram/10 minutes, be a component after the low molecular polyethylene powder that add 160 gram di-t-butyl peroxides in 7.12 kilograms of the acrylic resins, add 213.6 grams again stir; In addition, evenly make another component putting into 72 gram low molecular polyethylene powder mixes in the pre-dispersed good red pigment of 1800 grams, two kinds of components are put into hopper respectively, control is metered in the twin-screw extruder respectively, extruding pelletization under 160 ℃～230 ℃ temperature, the red cooling of the polypropylene of making masterbatch melting index is 47 grams/10 minutes.
Spinning behind the red cooling of the blending 60 grams masterbatch in 3 kilograms of acrylic resins, spinning temperature is 180 ℃～275 ℃, 550 meters/minute of winding speeds, stretch 4.83 times, the fibre breakage intensity of spinning was 5.16 gram/dawn, extension at break 18.3%, high-quality fiber bright in colour.
