Abstract

The invention discloses needled graphene nonwoven fabric and a preparation method thereof. The needled graphene nonwoven fabric comprises a needled nonwoven fabric layer and a graphene layer, whereinthe graphene layer is finished and compounded on the needled nonwoven fabric layer through a printing process; and the preparation method comprises the steps of (1) providing needled nonwoven fabric;(2) preparing a graphene finishing agent; (3) printing; (4) drying; and (5) baking. According to the preparation method of the needled graphene nonwoven fabric, printing treatment is carried out by adopting existing needled nonwoven fabric and the graphene finishing agent, and the graphene layer is evenly distributed on the needled nonwoven fabric, so that the preparation method disclosed by the invention has the advantages that the constraint of an existing graphene fiber and resin fiber blend spinning process is broken through; the preparation method has the advantages of being low in energyconsumption, simple in technological process, easy to operate and low in cost, and is suitable for industrial production; and the prepared needled graphene nonwoven fabric is relatively low in cost,has health protection performance and has a broad application prospect in the field of hot compress eyecups.

Description

Technical field [0001] The invention relates to the application and manufacturing field of non-woven fabrics, in particular to a graphene needle punched non-woven fabric and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms and sp² hybrid orbitals. Graphene powder has good hydrophilicity, excellent bacteriostasis and cell compatibility, and has important application prospects in the medical field. Graphene-containing non-woven fabrics have good performance in anti-bacterial, anti-mite, anti-static, anti-ultraviolet, thermal conductivity and far-infrared health care, so it can be used as a material for hot compress eye masks. [0003] However, current non-woven fabrics containing graphene are mostly prepared by co-spinning graphene fibers and resin fibers, or graphene membranes are prepared and compounded in a non-woven fabric layer. For these two preparation met...
