Embodiment 1

[0012] An antistatic masterbatch based on PET blending modification, its components are proportioned by mass percentage: PET resin 47%, polyethylene oxide 15%, titanium dioxide 25%, nano barium sulfate 10%, titanium dioxide Ester coupling agent 0.2%, sodium stearate 0.3%, superfine TAS-2A powder 2.5%.

[0013] Preparation method: Weigh each component according to the weight ratio, first add nano-barium sulfate and titanate coupling agent into a high-speed mixer with a cylinder temperature of 80°C-120°C, and stir at a speed of 3000-6000r / min 30-45 minutes, then add PET resin, polyethylene oxide, titanium dioxide, sodium stearate and superfine TAS-2A powder, stir together at a medium speed for 3-5 minutes, after mixing evenly, add double In a screw extruder, melt and knead at a temperature of 270°C to 290°C, extrude and granulate, then dry and package to obtain the antistatic masterbatch based on PET blending modification of the present invention.

Embodiment 2

[0015] An antistatic masterbatch based on PET blending modification, its components are proportioned by mass percentage: 37% of PET resin, 20% of glycerol monostearate and sodium alkyl sulfonate compound, Phthalocyanine blue 15%, nano barium sulfate 25%, titanate coupling agent 0.5%, sodium stearate 0.5%, superfine TAS-2A powder 2%.

[0016] Preparation method: Weigh each component according to the weight ratio, first add nano-barium sulfate and titanate coupling agent into a high-speed mixer with a cylinder temperature of 80°C-120°C, and stir at a speed of 3000-6000r / min 30 to 45 minutes, then add PET resin, glycerol monostearate and sodium alkyl sulfonate compound, phthalocyanine blue, sodium stearate and superfine TAS-2A powder, stir together at medium speed After 3 to 5 minutes, after mixing evenly, the material is discharged into a twin-screw extruder, melted and kneaded at a temperature of 270°C to 290°C, extruded and granulated, and then dried and packaged to obtain the...

Abstract

The invention discloses an antistatic color master batch based on PET blending modification. The comprises the following ingredients, by weight, 15%-50% of PET resins, 10%-20% of antistatic agent, 15%-30% of pigments, 5%-30% of nano barium sulfate, 0.1%-1% of titanate coupling agents, 0.1%-1% of sodium stearate and 0.5%-3% of ultrafine TAS-2A powder. The antistatic agent is one selected from polyethylene oxide, polyether ester amide, glycerol monostearate and alkyl sodium sulfonate compounds and nano antimony doped tin oxide. The beneficial effects are that the antistatic color master batch has characteristics of high concentration, high dispersion, strong coloring, low cost, excellent antistatic property, convenient usage and the like, 3%-10% of the antistatic color master batch by weight is added in PET production, a surface resistivity of a product can be lowered to 10<9>-10<10> omega.m, the mechanical properties and heat resistance of the material can be raised obviously, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antistatic color masterbatch based on PET blending modification. Background technique [0002] Polyethylene terephthalate (PET) is a crystalline linear polyester, commonly used in fibers, extruded films and sheets, blow molding, etc., due to its good gas barrier properties, toughness, elongation and mechanical strength , and has excellent transparency and environmental friendliness, has been widely used in fiber, film, engineering plastics and other fields. However, because of its large volume resistance, PET is very easy to generate static electricity, so its application in some fields is limited. Contents of the invention [0003] The object of the present invention is to provide a kind of antistatic color masterbatch based on PET blending modification. [0004] The technical solution adopted by the present invention to solve the technical problem is: antistati...
