Description
Technical field
The present invention relates to a kind of black functional agglomerate and preparation method thereof, more particularly to a kind of special black masterbatch of weather-proof tubing
Grain.
Technical background
Black agglomerate is mainly used in fiber product（Carpet, terylene, non-woven fabrics etc.）, blow molded article（Packaging bag, curtain coating
Film, multilayer complex films etc.）, blow-molded article（Medicine and cosmetics containers, paint container etc.）, extrudate（Sheet material, tubing, electricity
Cable, electric wire etc.）, injection-molded item（Auto parts machinery, electrical equipment, building materials, commodity, toy, sports goods etc.）.It has user
Just, to shaping environmental nonpollution, uniform coloring, stabilization, plastic part quality is improved, is easy to measure, automated procedures can be applied
Forming production system high, can coloring, anti-aging, antistatic etc. integrated the advantages of prepare multifunctional mother granules, convenient use.
New type plastic pipe has PE pipes, PP-R pipes, PP-C pipes etc. faster for recent year development, and it has density
Small, intensity is high, good corrosion resistance, the advantages of nontoxic, heat-insulation and heat-preservation is good, installation facilitates.It is widely used in drinking-water pipe
The field such as the cold and hot water supply system of system, building, air-conditioning system, floor heating system and chemistry, food, medical science.These modelings
Expects pipe material is typically both needed to use Masterbatch aborning.But common Masterbatch is due to using low-grade pigment, adding some low-grade
Additive, using common process, its degraded performance；Under ultraviolet light, macromolecule resin is excited generation free radical, so that
The strand of resin is destroyed, causes new type plastic pipe to produce color transfer in producing, it is serious to fade, it is impossible to anti-aging, subtract
Education and correction for juvenile offenders material service life, tube surfaces finish is poor, and color is matt.
The content of the invention
In view of this, it is an object of the invention to provide a kind of special black agglomerate of weather-proof tubing of ultraviolet resistance.
The present invention is achieved through the following technical solutions：
A kind of special black agglomerate of weather-proof tubing, it is characterised in that proportioning is its composition by mass percentage：
Vector resin：50~70%；Carbon black：25~50%；Auxiliary agent：5~10%；The auxiliary agent is antioxidant and lubricant；The charcoal
Black particle diameter is 23nm-27nm.
Carbon black can prevent resin because aging by ultraviolet irradiation, and carbon black can absorb ultraviolet, when dispersion in the plastic
When carbon black aggregate and agglomerate are irradiated by ultraviolet, the scattering of ultraviolet can be caused, then scatter light also by the aggregation of carbon black
Body and agglomeration collective absorb, so that the ultraviolet of Polymer absorption is substantially reduced.The master batch and tubing that carbon black will be added with are mixed
Close, the ultraviolet resistance ability of tubing can be improved, resist the aging of tubing.Particle size carbon black is too small, and the ultraviolet resistance ability of master batch subtracts
It is weak；Particle size carbon black is too high, and dispersiveness is too poor, and master batch shaping glossiness, blackness is relatively low, therefore from the distribution of suitable particle size carbon black
It is 23nm-27nm.
Preferably, the volatilization of the carbon black is divided into 0.5-1.0%.Carbon blacksurface has the oxygen-containing groups such as hydroxyl, carboxyl, carbonyl
The combined with radical that group can decompose with polymer, understands the free radical produced under resin illumination, prevents resin from further decomposing, and selects
It is divided into 0.5-1.0% with volatilization.Black agglomerate is added in tubing, the ultraviolet-resistant performance of tubing can be improved.
The volatile matter of carbon black uses the standard testings of DIN 53552,950 DEG C of calcination temperature.
Preferably, the vector resin is the one kind in acrylic resin, polyvinyl resin, is gathered using stability is higher
Allyl resin, polyvinyl resin, the tubing after shaping have stronger water-fast weatherability.
Preferably, the antioxidant is selected from the one kind or several in antioxidant 1098, antioxidant 1010 or irgasfos 168
Kind.Antioxidant 1098, antioxidant 1010 or irgasfos 168 can preferably prevent acrylic resin, polyvinyl resin heating note
It is oxidized during modeling, selects various oxidant compoundings, with reference to more carbon black addition, can prevents from carrying using less antioxidant
Body resin is oxidized.
Preferably, the lubricant is selected from lubricant SEED, PE wax, glycerin monostearate, silicone or silicone oil
Kind.Lubricant SEED, PE wax, GMS, silicone or silicone oil can play lubrication in injection moulding process is heated, and prevent process
Middle generation frictional influence master batch glossiness, causes carbon black pellet too small, influences the ultraviolet-resistant performance of tubing.
GMS is glycerin monostearate.
Invention additionally discloses a kind of preparation method for preparing a kind of weather-proof special black agglomerate of tubing, the method includes
Following steps：
（1）Weighing each component by formula rate in claim 1 and being added to banbury carries out 10 ~ 20min of banburying, the material for obtaining
Crushed through disintegrating apparatus after cooling；
（2）Material after crushing is added in parallel dual-screw extruding machine, the screw slenderness ratio for controlling double screw extruder is
48 ~ 50, extrusion temperature carries out extruding pelletization for 150 ~ 240 degree, and underwater cutpellet is carried out to it, and black agglomerate is obtained after drying.
Long using batch (-type) banburying and screw rod radially compare 42, it is ensured that vector resin, carbon black and auxiliary agent are sufficiently mixed,
Master batch stable performance after melt forming.
Preferably, described double screw extruder is divided into 9 sections, and the extrusion temperature from the first warm area to the 9th warm area is followed successively by
220 oC -240 oC -240 oC -240 oC -230 oC -220 oC -230 oC -230 oC -230 oC
Multistage extrusion temperature ensures the homogenizing of melt, is further ensured that the stability of shaping stepmother graininess energy, adds the master batch
Tubing weather resistance is superior.
The present invention also provides a kind of weatherability tubing containing the weather-proof special black agglomerate of tubing, the weather-proof tubing
The quality of special black agglomerate is with the mass ratio of the weatherability tubing：1-6%, can preferably improve the ultraviolet resistance of tubing
Performance.
Preferably, the quality of the special black agglomerate of weather-proof tubing is with the mass ratio of the weatherability tubing：2-5%.
The addition of the weather-proof special black agglomerate of tubing is 5%, and the ultraviolet-resistant performance of tubing is more preferable.
