preparation example Construction

[0049] The preparation method of antistatic masterbatch provided by the invention comprises the steps:

[0050] (1) In terms of parts by mass, the measured polyester chips, nano antistatic agent and antioxidant are added to the twin-screw extruder through a weight loss scale for full mixing, homogenization and devolatilization to obtain molten mixture;

[0051] (2) The molten mixture obtained in step (1) is pressurized by a melt pump, filtered through a filter, and extruded through a die to obtain a strip-shaped molten product; the molten material is cooled by a water tank, and then continuously passed through the The antistatic masterbatch is obtained by drying in a water tank and hot air to remove water, cutting into pellets and packaging.

[0052] The temperature of each zone of the twin-screw extruder is 200-300° C., the rotational speed of the main engine is 200-800 rpm, and the aperture of the filter screen is 20-100 um. The water temperature of the water tank is 5-25°...

Embodiment 1

[0059] Add 100 parts of PET polyester chips, 30 parts of nano-graphite, 0.1 part of antioxidant 168 and 0.1 part of antioxidant 1010 to the twin-screw extruder through a weight loss scale, prepare antistatic masterbatch according to the above method, and obtain antistatic masterbatch Grain A1.

[0060] The temperature of each zone of the twin-screw extruder is 220-280°C, the speed of the main engine is 600rpm, and the filter screen aperture is 50um.

Embodiment 2

[0062] In terms of parts by mass, 100 parts of PET polyester chips, 40 parts of nano-ATO powder, 0.1 part of antioxidant 168 and 0.1 part of antioxidant 1010 were added to the twin-screw extruder through a weight loss scale, and the antistatic Masterbatch, obtain antistatic masterbatch A2.

[0063] The temperature of each zone of the twin-screw extruder is 220-280°C, the speed of the main engine is 500rpm, and the filter screen aperture is 20um.

Abstract

The invention relates to the field of high polymer materials, in particular to an antistatic master batch for polyester films and a preparation method of the antistatic master batch. The invention provides the antistatic master batch and the preparation method thereof so as to overcome the defects that the existing antistatic agent is incompatible with polyester materials and is easily precipitated on the surface of a film so that the antistatic effect of the film is reduced, and large adding quantity is required so that the physical performance of the film is affected. The antistatic master batch provided by the invention comprises 100 portions of polyester chip, 5-70 portions of nanometer antistatic agent and 0.1-5 portions of antioxidant. The preparation method of the antistatic master batch provided by the invention comprises the steps of mixing raw materials by melting and then extruding and granulating. The antistatic master batch provided by the invention has the advantages of good compatibility with the film, difficulty in transfer, small adding quantity in the polyester films and good antistatic effect. The preparation method of the antistatic master batch has the advantages of simple process and easiness in operation.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an antistatic master batch for polyester film and a preparation method thereof. Background technique [0002] Today's world has entered the information age, and electromagnetic waves of various frequencies and wavelengths fill the entire space of the earth. These electromagnetic waves will cause varying degrees of interference to unshielded sensitive electronic components, circuit boards, communication equipment, etc., resulting in data distortion, communication disorder. The static electricity generated by electromagnetic induction and friction strongly interferes with various sensitive components, instruments and meters, and some chemical products; if the high-voltage discharge is generated due to the accumulation of static electricity in the packaging film, the film will be destroyed, so the application range of antistatic film is becoming more and more widely. The main mate...
