Abstract
The invention discloses black master batch for polyester and a preparation method thereof. The color master batch for polyester is prepared from the following components by mass percentage: 60-90% of pigment, 15-30% of carrier, 0.1-2% of dispersant, and 0.1-1% of anti-oxidant. The beneficial effects reside in that: when used for coloring a polyester product, the polyester black master batch provided by the invention has advantages of good dispersibility and stable color, overcomes easy generation of problems of uneven color, big aberration and influence on intensity of the polyester product when the general master batch is used for coloring polyester in the prior art, avoids environment pollution, guarantees color and purification of the product, and is convenient for using. The preparation method provided by the invention has advantages of simpleness, practicality and wide application prospect.
Description
Technical field
The present invention relates to field of plastic coloring, specifically a kind of Color concentrates for polyesters and preparation method thereof.
Background technology
Polyester comprises that polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and PEN (PEN) belong to a family macromolecule polymkeric substance, are widely used in the fields such as household electrical appliances, electronic apparatus, automotive industry, mechanical means, packing owing to having excellent over-all properties and processing characteristics.Yet, at the colorize method of producing polyester, have that toner is painted, dyeing draws painted three kinds of the painted and Masterbatch of grain.While directly adopting toner painted, painted very simple, but exist, easily produce color dot, aberration is wayward, environmental pollution is larger shortcoming.It is after polyester and toner are mixed, to adopt mixing facilities as painted in twin screw extruder carries out melt blending that dyeing draws grain painted, toner is painted to be compared with adopting, draw a coloring effect to be greatly improved, but polyester need experience twice heating, not only improve production cost, and damaged to a certain extent the mechanical property of goods.While adopting Masterbatch painted, pigment is also dispersed in vector resin through pre-treatment, has greatly improved dispersing property and the coloration efficiency of pigment, has the advantages such as simple to operate, with low cost, environmentally safe.
Summary of the invention
The object of the present invention is to provide Color concentrates for polyesters of a kind of colour stable, uniform coloring, good dispersity and preparation method thereof, it can overcome the problems such as easy generation flow liner, color and luster is uneven, aberration is larger while being applied to polyester article painted.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Color concentrates for polyesters, its component by mass percent proportioning is: pigment 60%～90%, carrier 15%～30%, dispersion agent 0.1%～2%, oxidation inhibitor 0.1%～1%.
Described pigment is mineral dye or pigment dyestuff, and described mineral dye is a kind of in titanium dioxide (titanium dioxide), carbon black, cadmium pigment and aluminium powder pigment, and described pigment dyestuff is a kind of in azo pigment, phthalocyanine pigment and heterocycle pigment.
Described carrier is the mixture of one or more arbitrary proportions in polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and PEN (PEN).
Described dispersion agent is a kind of in low molecular weight polyethylene wax, montanin wax, Magnesium Stearate, calcium stearate.
Described oxidation inhibitor is the compound of hindered phenol antioxygen 1076 and phosphite antioxidant 168.
The preparation method of above-mentioned a kind of Color concentrates for polyesters is: each component is prepared burden by weight proportion, then in high-speed mixer, mix 5～20 minutes, adopt again twin screw extruder melt blending, temperature is controlled at 180 ℃～200 ℃, screw speed is 80～400 revs/min, by the shearing of twin screw extruder, the mixing pigment that makes, in carrier, be uniformly dispersed, then carry out granulation, dry after packing obtain a kind of Color concentrates for polyesters.
The invention has the beneficial effects as follows, when a kind of Color concentrates for polyesters provided by the invention is applied to polyester article painted, it has advantages of good dispersity, colour stable, having overcome prior art uses general master batch coloring polyester easily to produce color and luster inequality, aberration greatly and affects the problems such as polyester article intensity, avoid environmental pollution and guaranteed the purity of combinations color and lustre, and easy to use, preparation method provided by the invention is simple and practical, has a extensive future.
