Example Embodiment
[0041] Example 1
[0042] In this embodiment, 10 parts of porous graphene oxide, 47 parts of acrylate, 0.045 parts of potassium persulfate, 0.90 parts of N,N'-methylenebisacrylamide, 0.05 parts of sodium lauryl sulfate, and azodimethyl 0.9 parts of amide, a spunbonded non-woven fabric treated with hydrophilic finishing, the square gram weight is 20g / m 2 .
[0043] In this example, the nonwoven fabric for the wrapping layer of the absorbent core was prepared according to the following steps:
[0044] Step 1: Prepare the acrylate with deionized water as a solution with a concentration of 30%-45%, add sodium lauryl sulfate and azodicarbonamide and stir for 5-30 minutes.
[0045] Step 2: Add porous graphene oxide to the solution of step 1, and use ultrasonic dispersion for 30-60 minutes to obtain graphene suspension mixture A.
[0046] Step 3: The graphene suspension mixture of step 2 is heated to 42-85°C, then N,N'-methylenebisacrylamide is added, and the mixture is uniformly dispersed ul...

[0056] Example 2
[0057] In this example, 50 parts of porous reduced graphene, 10 parts of acrylic acid, 0.001 parts of potassium persulfate, 0.30 parts of N,N'-methylenebisacrylamide, 0.2 parts of sodium lauryl sulfate, and azodicarbonamide 0.2 parts, hot-rolled non-woven fabric treated with hydrophilic finishing, with a square weight of 18g / m 2 .
[0058] According to the preparation method of Example 1, a graphene coating is formed on the surface of the nonwoven fabric for the wrapping layer of the absorbent core. The graphene coating includes a porous polymer with a three-dimensional network of cross-linked structure. Graphene is uniformly dispersed and immobilized in the structured porous polymer body, and the cross-linked structured porous polymer body has through holes that penetrate each other and penetrate to the nonwoven fabric substrate, and the pore size of the through holes is 50-2000 microns , So that this embodiment has the effect of quickly penetrating liquid down...
