Embodiment 1

[0060] Production of modified polypropylene masterbatch:

[0061] Graphene powder (graphene C with screening particle size ≤ 10 μm), polypropylene slices, coupling agent (remixed butyl titanate and isopropyl titanate), dispersant (polyethylene wax) and antioxidant (Tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid]pentaerythritol ester) was added to the high-speed mixer for mixing After being mixed evenly, it is added to a twin-screw extruder, melted and extruded, cooled in a water bath, and cut to make a graphene composite polypropylene masterbatch.

Embodiment 2

[0063] The difference from Example 1 is that the ratio of raw materials is different, and the percentages of graphene powder, polypropylene chips, coupling agent, dispersant and antioxidant are respectively:

[0064] 15%, 82%, 2%, 0.99%, 0.01%.

Embodiment 3

[0066] The difference from Example 1 is that the ratio of raw materials is different, and the percentages of graphene powder, polypropylene chips, coupling agent, dispersant and antioxidant are respectively:

[0067] 5%, 90%, 2%, 2.8%, 0.2%.

Abstract

The invention provides a modified polypropylene master batch, melt-blow cloth, a preparation method and an application thereof. The modified polypropylene master batch is mainly produced from, by weight, 77-90% of polypropylene, 5-20% of a graphene material and 1-5% of an additive. The graphene material includes any one or more of graphene, graphene oxide and graphene derivative. The additive includes any one or more of a coupling agent, a dispersant and an antioxidant and preferably includes the coupling agent, the dispersant and the antioxidant. The modified polypropylene master batch, when being used for manufacturing the melt-blow cloth, not only improves antibacterial and electrification property but also increases the filtering efficiency and dust capacity of the melt-blow cloth.

Description

technical field [0001] The invention relates to the field of melt-blown cloth, in particular to a modified polypropylene masterbatch, a melt-blown cloth, a preparation method thereof, and an application of the modified polypropylene masterbatch. Background technique [0002] Melt-blown cloth is made by extruding high-polymer resin through a screw extruder to melt and plasticize it, and then accurately metering it to the spinneret assembly through a metering pump. formed nonwoven fabric. Because the melt-blown cloth has very fine, large specific surface area, small pores and large porosity, it has good filterability, shielding, heat insulation and oil absorption, and is widely used in medical and industrial masks and thermal insulation materials. , filter materials, medical and health materials, oil-absorbing materials, battery separators, and sound-insulating materials. At the same time, functional melt-blown cloth has become a research hotspot because of its multifunctiona...
