Embodiment 1

[0013] A color masterbatch for polyester, its components are proportioned by mass percentage: titanium dioxide (titanium dioxide) 70%, polyethylene terephthalate (PET) 28%, low molecular weight polyethylene wax 1.5%, Compound of hindered phenol antioxidant 1076 and phosphite antioxidant 168 0.5%.

[0014] Preparation method: mix each component according to the weight ratio, then mix in a high-speed mixer for 5-20 minutes, and then use a twin-screw extruder to melt and blend, the temperature is controlled at 180°C-200°C, and the screw speed is 80-400 rotation per minute, through the shearing and mixing of the twin-screw extruder, the titanium dioxide (titanium dioxide) is uniformly dispersed in the polyethylene terephthalate (PET), and then granulated, dried and packaged to obtain a A kind of masterbatch for polyester.

Embodiment 2

[0016] A color masterbatch for polyester, its components are proportioned by mass percentage: titanium dioxide (titanium dioxide) 80%, polybutylene terephthalate (PBT) 18%, calcium stearate 1%, hindered The compound of phenol antioxidant 1076 and phosphite antioxidant 168 is 1%.

[0017] Preparation method: mix each component according to the weight ratio, then mix in a high-speed mixer for 5-20 minutes, and then use a twin-screw extruder to melt and blend, the temperature is controlled at 180°C-200°C, and the screw speed is 80-400 RPM, through the shearing and mixing of the twin-screw extruder, the titanium dioxide (titanium dioxide) is uniformly dispersed in the polybutylene terephthalate (PBT), and then granulated, dried and packaged to obtain a A kind of masterbatch for polyester.

Embodiment 3

[0019] A color masterbatch for polyester, its components are proportioned by mass percentage: azo pigment 78%, polyethylene naphthalate (PEN) 20%, montan wax 1.5%, hindered phenol antioxidant The compound of 1076 and phosphite antioxidant 168 is 0.5%.

[0020] Preparation method: mix each component according to the weight ratio, then mix in a high-speed mixer for 5-20 minutes, and then use a twin-screw extruder to melt and blend, the temperature is controlled at 180°C-200°C, and the screw speed is 80-400 rev / min, through the shearing and mixing of the twin-screw extruder, the azo pigment is uniformly dispersed in polyethylene naphthalate (PEN), and then granulated, dried and packaged to obtain a polyester Use masterbatch.

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 [0001] The invention relates to the field of plastic coloring, in particular to a color masterbatch for polyester and a preparation method thereof. Background technique [0002] Polyesters including polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and polyethylene naphthalate (PEN) belong to a class of high molecular polymers, due to their Excellent comprehensive performance and processing performance are widely used in household appliances, electronic appliances, automobile industry, mechanical equipment, packaging and other fields. However, there are three kinds of coloring methods in the production of polyester: toner coloring, dyeing and dyeing, and masterbatch coloring. When directly using toner for coloring, the coloring is very simple, but it has the disadvantages of easy to produce color spots, difficult to control color difference, and great environmental pollution. Dyeing and granulation coloring is to mix polyester and toner and...
