Abstract

The invention relates to a non-woven fabric for absorbing a core wrapping layer. The non-woven fabric comprises a non-woven base material, wherein the non-woven base material is subjected to hydrophilic finish treatment, the surface layer of the non-woven base material is further coated with a graphene coating, the graphene coating is of a three-dimensional network-like cross-linking structure; the three-dimensional network-like cross-linking structure comprises a cross-linked structure porous polymer continuous phase and graphene which is uniformly dispersed and immobilized in the cross-linked structure porous polymer continuous phase; the three-dimensional network-like cross-linking structure comprises, by weight, 10-50 parts of graphene, 5-47 parts of cross-linking structure porous polymer and activated carbon; through holes which are communicated with one another and penetrate into the non-woven base material are formed in the cross-linked structure porous polymer; the cross-linkedstructure porous polymer is formed by initiating polymerization through polymerization monomers, a pore forming agent and an initiator and conducting cross-linking through a cross-linking agent, at the same time, the through holes are formed, and the size, density and the like of the through holes can be adjusted through the pore-forming agent for ordinary technicists in the field.

Description

technical field [0001] The invention relates to the technical field of disposable hygienic materials, in particular to a nonwoven fabric for an absorbent core wrapping layer. Background technique [0002] Graphene refers to a single layer of carbon atoms tightly packed into a two-dimensional honeycomb structure, which is the basic unit for constructing other dimensional carbon materials (such as zero-dimensional fullerenes, one-dimensional carbon nanotubes, and three-dimensional graphite). Single-layer graphene has a large specific surface area, excellent electrical and thermal conductivity and low thermal expansion coefficient. In particular, its high conductivity, large specific surface properties and its monolayer two-dimensional nanoscale structural properties can be used as electrode materials in bipolar plates of fuel cells, supercapacitors and lithium-ion batteries. [0003] In addition, researchers have found that graphene has certain antibacterial properties in pre...
