Abstract
The present invention discloses a black agglomerate technology special for styrene class resin, which comprises 20 to 35% of pigment black (black carbon), 15 to 30% of dispersion lubricant and 45 to 65% of carrier resin. The present invention has the preparation method that all components are premixed proportionally firstly; then all the components are kneaded in a high-speed kneading machine at the rotary speed of 800 to 150/min, a mix material thoroughly kneaded is added in a double screw extruder to be extruded finally, and the mix material is cooled, dried and pelletized to manufacture the required agglomerate. The present invention has the characteristics of less addition amount, strong dispersivity, higher temperature resistance, light resistance, stability, etc.; furthermore, the agglomerate can not influence the mechanical properties of the styrene for being added in the styrene class resin, and a black plastic product with uniform blackness and high glossiness and without dyeing defects can be obtained after injection moulding.
Description
Affiliated technical field
The present invention relates to the coloring plastic technical field, particularly relate to a kind of black agglomerate that is exclusively used in styrene resin.
The invention still further relates to this preparation method who is exclusively used in the styrene resin black agglomerate.
Background technology
At present, the styrenic engineering plastics, have superior mechanical property as general purpose polystyrene (GPS), high-impact polystyrene (HIPS), acrylonitrile-styrene-butadienecopolymer (ABS) etc., occupy an important position in each Application Areass such as machinery, automobile, household electrical appliances, national defence.Along with the progressively expansion of engineering plastics range of application, under the situation that its specification of quality and quality standard also improve constantly thereupon, existing Masterbatch and preparation technology thereof oneself through not satisfying engineering plastics far away in the requirement aspect physical strength and the dispersing property.Because the bad dispersibility of this master batch, particularly when the plastics size was big, it is more outstanding that its shortcoming just seems.Simultaneously, existing colour batch addition generally just can reach satisfied dispersion effect between 3-4%, because addition is bigger, thereby very easily influences the mechanical property of material.
Summary of the invention
For the deficiency that the black masterbatch that overcomes present styrene resin exists, the purpose of this invention is to provide a kind ofly have the concentration height, easily disperse, addition is few and add after do not influence the black agglomerate that is exclusively used in styrene resin of its mechanical property.
Another object of the present invention provides this preparation method who is exclusively used in the black agglomerate of styrene resin.
Realize that the technical scheme that the object of the invention adopted is: this black agglomerate that is exclusively used in styrene resin, the weight percent of its each component is:
Black pigment (carbon black) 20-35%
Dispersed lubricant 15-30%
Vector resin 45-65%
The particle diameter of said black pigment (carbon black) pigment is 10-30nm, its function is except that using as dyeing, can also be as UV light stabilizing agent, can prevent effectively that plastics are subjected to solar radiation and produce the light ammonification and degrade, thus the quality and the work-ing life of improving plastics.
Said dispersed lubricant is that first fusing point is that 140 ℃-150 ℃ ethylene bis stearic acid amide (EBS), stearic acid series dispersion agent, first fusing point are that 100 ℃-106 ℃ and molecular weight are the polyethylene wax of 3000-5000 and/or the mixture of these compounds.Ethylene bis stearic acid amide (EBS) is as the core dispersion agent, and dispersed strong, usage quantity is few, but also has the characteristics of lubricant and brightening agent concurrently, can give the appearance of the level and smooth light of plastics.Its colour (iodine colorimetric)<=5.0, acid number<=10.0mg/g, amine value<=2.5mg/g, weight loss on heating<=0.5%, fineness<=20nm.Stearic acid series dispersion agent comprises Zinic stearas, Magnesium Stearate.
Said vector resin is at least one or more in high-impact polystyrene, ethylene-vinyl acetate copolymer resins (EVA), styrene resin and the multipolymer (as GPS, HIPS, ABS) thereof.Vector resin ethylene-vinyl acetate copolymer resins (EVA), melt flow rate (MFR) are (0.3-4.0) g/10min, and its molecular structural formula is:
Owing to introduced VAM on the molecular chain, thereby reduced degree of crystallinity, improved the sneaking into property and the heat seal of snappiness, impact and the filler of goods.Simultaneously, have good optical performance, low temperature resistant and nontoxic characteristic, thereby the Masterbatch that adds this vector resin can not influence the mechanical property and the printing performance of goods.
Preparation is exclusively used in the method for styrene resin black agglomerate: earlier each component is carried out pre-mixing in proportion; in being the high speed kneader of 800-1500/min, rotating speed mediates 15-60min then; the compound that to fully mediate at last adds in the twin screw extruder to be extruded, and makes required master batch after cooling, oven dry, pelletizing (or using the tablets press granulation).
Prior art of the present invention is compared, and has advantages such as few, the easy dispersion of addition, blackness height, strong covering power, and is applicable to the painted of multiple polyolefin resin, does not influence the mechanical property and the printing performance of goods, can be widely used in the painted of styrene resin.
