Problems solved by technology

This will cause static electricity on the film to be difficult to disappear through conduction due to friction and other reasons during the production or processing of polypropylene film, which will bring problems to the production, processing and application of the film.
[0005] Antistatic PP film is first applied in the fields of powder packaging, food packaging, candy packaging, etc. Because of the accumulation of static electricity, it will cause dust or other dirt in the air of the PP film daughter-in-law, which not only affects the appearance of the film surface, but also in the Electrostatic adsorption will also occur during use, affecting normal use

[0052] The dispersibility experiment is detected by the following method: 10 mg of activated carbon nanotubes prepared in Examples 1 to 16 are added to 10 mL of the solvent (see Table 1) used to prepare the activated carbon nanotubes, and ultrasonically dispersed for 30 minutes to obtain a suspension solution, stand still, and when obvious stratification occurs, the recorded time is the storage time, and the results are shown in Table 2. Th...

Embodiment 17～32

[0055] The activated carbon nanotubes prepared in Examples 1 to 16 and the PP polymer powder material (average particle diameter 100 μm to 2 mm) were stirred and mixed, and then mixed with auxiliary agents. The dosage of each raw material is shown in Table 3 and Table 4. The PP / carbon nanotube conductive masterbatch is obtained by melt extrusion, stretching, cooling and granulation of the screw extruder; the processing technology of the twin-screw extruder is that the screw speed is 200r / min, and the extrusion temperature is 180°C.

Abstract

The invention discloses an activated carbon nanotube modified polypropylene (PP) antistatic film. The PP antistatic film is prepared from the following components in parts by mass: 70-95 parts of PP base materials, 0.01-10 parts of activated carbon nanotubes and 0.1-20 parts of an aid, wherein the aid is one or a mixture of two or more of a dispersant B, a coupling agent, an antioxidant, a lubricant and an abrasive agent; an activated carbon nanotube is prepared through the following steps: the dispersant A is dissolved in a solvent, and a dispersant solution is obtained; then, the dispersant solution is sprayed into the carbon nanotube stirred at a high speed with a high pressure spray method, and the activated carbon nanotube is prepared after high-speed stirring and mixing. The PP antistatic film has good conductivity, high antistatic durability and long service life.

Description

[0001] 1. Technical field [0002] The invention relates to an active carbon nanotube modified polypropylene antistatic film. [0003] 2. Background technology [0004] As one of the five general-purpose plastics, polypropylene (PP) has rich sources of raw materials, low price, easy processing and molding, excellent mechanical properties, heat resistance, and comprehensive properties, and is non-toxic and easy to recycle. Therefore, its films and film products are widely used in many industries. fields have been widely applied. Because polypropylene molecules are non-polar and have high electrical insulation, its surface resistivity is 10 16 ~10 17 Ω, volume resistivity 10 16 ~10 18 Ω·cm. Therefore, relatively speaking, polypropylene is relatively easy to generate static charge accumulation among polymer materials. And once the accumulation of static electricity occurs, its harm cannot be underestimated. This will lead to static electricity on the film due to friction an...
