Description
Technical field
Belong to PVC material field herein, more particularly to a kind of hard PVC color masterbatch and preparation method thereof.
Background technology
PVC is polyvinyl chloride, is one of earliest industrialized plastics variety, using extremely wide.Current China polyvinyl chloride resin
Annual production more than 1,000,000 tons, with the appearance of PVC expensive goods and continuous prodution the need for, to PVC plastic color articles
It is required that also more and more higher.Thus, PVC plastic is coloured and can not be met life using traditional " floating dye method " and " mill base method "
Producing needs.
When color masterbatch is used in the plastic, can make pigment that there is preferably dispersiveness in product, be conducive to keeping pigment
Chemical stability, keep the cleaning of environment, operation is simple, annesl easily, time-consuming and raw material, therefore in plastic industry
Using widely, but because the plasticizing capacity of PVC is weak, and can decompose at high temperature, the making of PVC color masterbatch has certain difficulty
Degree, therefore, general producer is dyeed with toner (i.e. pigment) to PVC, and toner dyeing has following defect：
(1) pollution is big when stirring toner；
(2) changing color need to take a long time cleaning barrel；
(3) dispersiveness is poor；
A small number of domestic PVC color masterbatch are not that PVC is base-material at present, but are made for base-material is made with polyethylene etc.
With this color masterbatch pipe performance can be caused relatively low.There is extrudate with the making that PVC carries out color masterbatch as base-material cannot be into bar, color masterbatch
In there are problems that.
The content of the invention
For drawbacks described above, it is an object of the invention to provide one kind with polyvinyl chloride as base-material, hard PVC color masterbatch is prepared
Formula and preparation method thereof.A kind of hard PVC Masterbatch of the present invention, dispersiveness is high, while having weather-proof, use higher
In the dyeing of hard PVC material.
The technical scheme is that：
A kind of hard PVC color masterbatch, the color masterbatch is base-material, processing aid and toner to be mixed by double screw extruder extrude
Obtained from.
Its formula is calculated in parts by weight, comprising following components：
Said components are：
Said components are：
Above-mentioned hard PVC color masterbatch, the base-material is PVC granule.
Above-mentioned hard PVC color masterbatch, described filler is one or more mixing in calcium carbonate, barium sulfate, talcum powder.
Above-mentioned hard PVC color masterbatch, the plasticiser is dioctyl phthalate (DOP), di-n-octyl phthalate
(DNOP or DnOP), BBP(Butyl Benzyl Phthalate (BBP), di-sec-octyl phthalate (DCP), dicyclohexyl phthalate
(DCHP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), repefral (DMP),
In diethyl phthalate (DEP), diisononyl phthalate (DINP), diisooctyl phthalate (DIDP) one
Plant or more than one mixing.
Above-mentioned hard PVC color masterbatch, the dispersant is stearic acid, zinc stearate, paraffin, Tissuemat E, N, N- dimethyl
One or more mixing in acetamide.
Above-mentioned hard PVC color masterbatch, the lubricant is in stearic acid, butyl stearate, oleamide, ethylene bis stearamide
One or more mixing.
Above-mentioned hard PVC color masterbatch, the heat stabilizer is dibasic lead stearate, lead sulfate tribasic, dibasic neighbour's benzene
One or more mixing in diformazan lead plumbate, dibasic lead phosphite.
Above-mentioned hard PVC color masterbatch, the antioxidant is tetrapentaerythritol ester (KY-1010), propionic acid octadecanol ester (KY-
1076), one or more mixing in tris phosphite (PKY-168), bipentaerythrite diphosphites (JC-242).
Above-mentioned hard PVC color masterbatch, the light stabilizer is 2- (2 '-hydroxyl -3 '-tert-butyl group -5 '-aminomethyl phenyl) -5- chlorine
BTA (UV-326), 2- (2 '-hydroxyl -3 ', 5 '-di-tert-butyl-phenyl) -5- chlorobenzotriazoles (UV-327), 2- hydroxyls -
One or more mixing in 4- oxy-octyl benzophenones (UV-531).
Present invention also offers the preparation method of above-mentioned hard PVC color masterbatch：
(1) by PVC base-material 35%-50%, filler 15%-25%, dispersant 2%-10%, lubricant 0.1%-5%, heat
Stabilizer 1%-5%, antioxidant 0.1%-3%, light stabilizer 0.1%-3% are inserted in high-speed mixer, are well mixed.
(2) reduce mixture temperature is carried out to the 30-45 DEG C of mixture addition 20%-30% plasticiser obtained to step (1)
Mixing.
(3) improve mixture temperature adds 5%-15% toners to be mixed to the 40-65 DEG C of mixture obtained to step (2)
Close.In the hopper such as double screw extruder being sent by mixture.
(4) adjust between 170-210 DEG C of the temperature of each subregion, it is 20-70r/min to control screw speed.
(5) bar is extruded into, cooling and dicing is dried, that is, Masterbatch is obtained.
The pigment of dyeing is made color masterbatch by the present invention for the defect that PVC plastic is dyeed with toner in the prior art,
Pollution, Simplified flowsheet will be reduced in PVC product production.
The proportion of filler added in the present invention is approached with filler accounting in PVC product, is reduced because addition color masterbatch causes PVC
Product in itself toughness reduction intensity decreases possibility, it is possible to reduce certain cost.
The plasticiser added in the present invention is inserted between polymer molecular chain because of its molecule, weakens polymer molecular chain
Between stress, increased polymer molecular chain movement possibility, reduce the winding between strand so that polyvinyl chloride resin mould
Property increase, make it easier to processing, reduce thickener generation.
The dispersant and lubricant added in the present invention have synergy, by the wetting action reduction to pigment molecule
Energy required for pigment dispersion, improves pigment particles surface nature, prevents pigment molecule from condensing, and allows pigment more
Good dispersion, increases color saturation, and makes the mobility of increase melt in processing and forming, is more readily processed PVC.
The lubricant added in the present invention can improve the mobility of melt, reduce the viscosity of melt and equipment room, reduce
The fusing point of color masterbatch, makes color masterbatch more readily dispersible.
The heat stabilizer added in the present invention can effectively suppress dehydrochlorination reaction when PVC is processed.Polyvinyl chloride resin heat
Stability is poor, and the unstability position for starting dehydrochlorination reaction is caused by adding heat stabilizer to eliminate, and effectively inhibits
The degraded of polyvinyl chloride resin.
The antioxidant added in the present invention can improve the oxidation resistance of product, increase the oxidation induction time of color masterbatch,
The possibility that the product coloured using color masterbatch reduces oxidation induction time is reduced, extends the service life of product.
The light stabilizer added in the present invention belongs to ultra-violet absorber, can effectively absorbing wavelength 240-380 nanometers
Ultraviolet, so as to reach the protective effect to polyvinyl chloride resin, suppress self oxidation of polymer and degrade, postpone light aging
The service life of process, extension pigment and PVC product.
