Abstract

The invention relates to a preparation method of a toilet paper product containing graphene, and discloses a process of medicinal plant papermaking. The process comprises the steps of screw extrusionprocessing, cooking, washing, papermaking, paper product modification, etc. The preparation method is characterized in that medicinal plant is used as a raw material to prepare fibers, and ultrasonicand ethanol methods are used in combination. The prepared paper product containing graphene has good softness and high strength, and no harmful chemicals are introduced during the whole process, so that the hygienic characteristic of the fibers is ensured; the prepared paper product has health care functions and effectively inhibits bacteria and resists bacteria; and since a graphene dispersion isadded during a pulping process, the obtained product has good antibacterial properties, and in particular, plays effective inhibiting and killing effects on staphylococcus aureus, escherichia coli, and streptococcus hemolyticus.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking, and in particular relates to a graphene-containing paper product and a preparation method thereof. Background technique [0002] Graphene is a new type of two-dimensional ultra-thin nanomaterial, because of its unique structure, mechanical and electronic properties, it has broad application prospects in the field of bio-nanotechnology such as drug delivery and tumor treatment. Studies have shown that graphene can not only cut the bacterial cell membrane, but also induce the detachment of phospholipid molecules on the bacterial cell membrane, so as to realize the large-scale direct extraction of phospholipid molecules on the cell membrane by graphene. The physical action of cutting and extracting can cause the bacterial cell membrane to lose its integrity and the intracellular material to flow out, thereby achieving the effect of killing the bacteria. At the same time, graphene is...
