Embodiment 1

[0014] A graphene diaper, comprising a liquid-permeable surface layer, an absorber, and a liquid-impermeable bottom layer sequentially stacked from top to bottom, the absorber is composed of an absorbent core wrapped in non-woven fabric, and the absorbent core is composed of fluff It is composed of pulp, polymer water-absorbing resin and graphene powder. The amount of fluff pulp, polymer water-absorbing resin, and graphene powder is 55:35:10 by weight.

[0015] The preparation method thereof comprises the preparation of an absorber, the absorber is composed of a non-woven fabric wrapped absorbent core, the absorbent core is composed of fluff pulp, polymer water-absorbing resin, and graphene powder, and the preparation method of the graphene powder For: (1) Oxidation and stripping of graphene: take natural flake graphite as raw material, adopt hummer method to obtain graphite oxide mother liquor, place this mother liquor in ultrasonic wave to disperse and realize stripping, obt...

Embodiment 2

[0017] Referring to Example 1, the amounts of fluff pulp, polymer water-absorbing resin, and graphene powder are calculated by weight = 50:35:15, and the others are the same as in Example 1.

[0018] In the present invention, the amount of fluff pulp, polymer water-absorbing resin, and graphene powder is calculated by weight = 50-60: 10-35: 3-15, and the object of the present invention can be achieved within the range of the above parameters.

[0019] The absorbent article of the present invention, in addition to diapers, can also be sanitary products such as sanitary napkins, panty liners, adult diapers, and pants-type sanitary napkins.

Abstract

The invention relates to the field of sanitation supplies, and provides a graphene absorbing object and a preparation method thereof with an aim to solve problems about poor liquid absorption effect, slow liquid absorption speed and no antibacterial efficacy in the prior art. The graphene absorbing object comprises a permeable surface layer, an absorber and an impermeable bottom layer which are laminated sequentially from top to bottom, the absorber is formed by wrapping an absorbing core with non-woven fabric, and the absorbing core is formed by mixing fluff pulp, super absorbent polymer and graphene powder.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to a graphene absorbent article and a preparation method thereof. Background technique [0002] Diapers are a kind of sanitary products commonly used by babies. Generally speaking, diapers are composed of three main parts: surface cover layer, absorbent core layer and base fabric. Surface coatings may also be referred to as coatings. The absorbent core may also be referred to as an absorbent core, or absorbent body. The cover fits snugly against the baby's body, which promotes quick penetration of urine and effectively prevents rewet, keeping the surface of the diaper dry. At present, the covering layer of diapers in the domestic market is basically a non-woven surface layer. The breathable non-woven fabric can improve the air permeability inside the diaper, and the water vapor can circulate outside the diaper, and the moisture and heat can be discharged in time, effectively redu...
