[0030] (3) Put the obtained mixture into a twin-screw extruder to extrude, draw strands, water-cool and pelletize to obtain a fully biodegradable color masterbatch. The temperature of each zone of the twin-screw extruder is: 90°C in the first zone, 110°C in the second zone, 120°C in the third zone, 130°C in the fourth zone, 140°C in the fifth zone, 150°C in the sixth zone, and 155°C in the head; the screw speed is 100rpm, and the long diameter The ratio is 40 / 1.

Embodiment 2

[0032] (1) Dry PBS (blown film grade, Anqing Hexing Company) in a blast oven at 60°C for 24 hours, and dry calcium carbonate (with a particle size of 800 mesh) in a blast oven at 105°C for 10 hours.

[0033] (2) Take 30 parts of PBS, 40 parts of carbon black, 30 parts of calcium carbonate, 0.5 parts of ADR-4370, 20 parts of calcium stearate, 0.1 parts of β-(3,5-di-tert-butyl-4-hydroxyphenyl ) Propionate octadecyl alcohol ester was mixed at high speed in a high-speed mixer for 15 minutes.

[0034] (3) Put the obtained mixture into a twin-screw extruder to extrude, draw strands, water-cool and pelletize to obtain a fully biodegradable color masterbatch. The temperature of each zone of the twin-screw extruder is: 90°C in the first zone, 110°C in the second zone, 120°C in the third zone, 130°C in the fourth zone, 140°C in the fifth zone, 150°C in the sixth zone, and 155°C in the head; the screw speed is 300rpm, and the long diameter The ratio is 44 / 1.

Embodiment 3

[0036] (1) PLA (4032D, NatureWorks) was dried in a blast oven at 70°C for 10 hours, and montmorillonite (with a particle size of 2500 mesh) was dried in a blast oven at 110°C for 8 hours.

[0037] (2) Take 60 parts of PLA, 20 parts of red powder, 20 parts of montmorillonite, 1.5 parts of ADR-4370, 15 parts of polyethylene wax, 0.5 parts of 2-methylenebis(4-methyl-6-tert-butyl Phenol) was mixed in a high-speed mixer for 10 minutes.

[0038] (3) Put the obtained mixture into a twin-screw extruder to extrude, draw strands, water-cool and pelletize to obtain a fully biodegradable color masterbatch. The temperature of each zone of the twin-screw extruder is: 150°C in the first zone, 160°C in the second zone, 170°C in the third zone, 175°C in the fourth zone, 175°C in the fifth zone, 170°C in the sixth zone, and 165°C in the head; the screw speed is 200rpm, and the long diameter The ratio is 48 / 1.

Abstract

The invention belongs to the technical field of high-molecular materials, and relates to a universal fully-biodegradable color masterbatch and a preparation method thereof. The universal fully-biodegradable color masterbatch comprises the formula compositions in parts by weight: 30-80 parts of biodegradable polyester, 10-40 parts of a pigment, 10-30 parts of a filler, 0.5-3 parts of a compatilizer, 5-20 parts of a lubricant and 0.1-0.6 part of an anti-oxidant. The fully-biodegradable color masterbatch is obtained through melt blending, extrusion, strip pulling and pelletizing by employing a double screw extruder. The fully-biodegradable color masterbatch is completely biodegradable, good in processing performance and good in dispersing effect in a matrix, and has extremely good compatibility with a polyester matrix even a masterbatch carrier and a biodegradable polyester matrix are different polyesters. The masterbatch gives play to extremely good coloring effect on a product when being applied to a biodegradable polyester.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a universal fully biodegradable color masterbatch and a preparation method thereof. Background technique [0002] The use of plastic materials has penetrated into all areas of people's lives, and is widely used as food packaging, electronic and electrical product packaging, shopping bags, garbage bags and disposable injection molding products. The raw materials of traditional plastic materials such as polypropylene (PP), polyethylene (PE), polystyrene (PS) are petroleum, which are difficult to degrade when discarded in nature after use, causing great harm to the environment. With the depletion of petroleum resources and the continuous enhancement of people's awareness of environmental protection, the development of fully degradable, environmentally friendly polymer materials used in the field of films and disposable injection molding products has become the mainstream of ...
