Abstract
The invention discloses a high-pigment plastic black master batch and a preparation method thereof. The high-pigment plastic black master batch is composed of the following components by weight percentage: 30-70% of carrier resin, 10-20% of high-pigment carbon black, 15-40% of rubber carbon black, 1-2% of dispersant and 1-3% of processing auxiliary agent. The preparation method comprises a two-step method process to firstly prepare a high-pigment black master batch dispersed body and further process and prepare the final-grade high-pigment black master batch. The carrier resin is polyolefin resin and is high-density polyethylene or linear low-density polyethylene or a commixture of the high-density polyethylene or the linear low-density polyethylene; the dispersant is polyethylene wax; and the processing auxiliary agent is high-viscosity methylsilicone oil. The high-pigment plastic black master batch and the preparation method thereof overcome the defects that the brightness of the single high-pigment carbon black is high, the covering rate is poor and the single high-pigment carbon black is not easy to disperse; and the rubber carbon black with the low cost and the high covering rate is added, so that the plastic black master batch with the carbon black concentration which reaches to 60% at maximum is prepared by the simplest double-screw process.
Description
Technical field
The invention belongs to the plastic master batch processing technique field, be specifically related to a kind of high pigment plastics black masterbatch and preparation method thereof.
Background technology
High-carbon black pigment is one of main raw material of plastics black masterbatch, but because the high-carbon black pigment apparent density is little, specific surface area is big, is difficult to be dispersed in the macromolecular material such as plastics.Prepare plastics black masterbatch method commonly used twin screw extrusion molding, Banbury mixer method and two rotors continuous mixing method are arranged; The advantage of twin screw extrusion molding is that equipment is simple, less investment; Weak point is that the black masterbatch carbon black concentration of being produced can not surpass 30%, and black hides rate variance.Though the two kinds of methods in back can make the high density black masterbatch, facility investment is big, and the plastics black masterbatch price of being produced is high.
Summary of the invention
The present invention is directed to problem and technology that existing black masterbatch production exists, propose a kind of high pigment black masterbatch and preparation method thereof,, produce the plastics black masterbatch of high pigment in the hope of with the simplest twin screw extruder production technique.
Technical scheme of the present invention is:
A kind of high pigment plastics black masterbatch is made up of vector resin, high-carbon black pigment, rubber carbon black, dispersion agent and processing aid, and the each component weight percent is: vector resin 30～70%; High-carbon black pigment 10～20%; Rubber carbon black 15～40%, dispersion agent 1～2%, processing aid 1～3%.
Said vector resin is a polyolefin resin, is high density polyethylene(HDPE) or linear low density polyethylene or both blends.
Said dispersion agent is a polyethylene wax.
Said processing aid is the HV methyl-silicone oil.
A kind of high pigment black masterbatch preparation method adopts two-step process:
The first step: prepare high pigment black masterbatch predispersion: vector resin, high-carbon black pigment, dispersion agent, processing aid mix through high-speed mixer earlier, add a blend granulation of twin screw extruder then, process elementary high pigment black masterbatch.
Second step: preparation is the high pigment black masterbatch of level eventually: said elementary high pigment black masterbatch, rubber black, dispersion agent, processing aid secondary mixed at high speed, add twin screw extruder secondary blend granulation again, and process final high pigment black masterbatch.
The invention has the beneficial effects as follows: it is high but hide rate variance and be difficult for the dispersive disadvantage to overcome the high-carbon black pigment blackness, adds at a low price but the high rubber carbon black of hiding rare, reaches as high as 60% plastics black masterbatch with the simplest twin screw prepared carbon black concentration.
