Preparation method of liquid sanitary towel absorption core body

The invention provides a preparation method of a liquid sanitary towel absorption core, which comprises the following steps: S1, mixing an acrylate monomer 1, a cross-linking agent, a photoinitiator and a surfactant to obtain an oil phase 1, and then adding a water phase A and a water phase B to obtain an HIPE emulsion 1; s2, mixing an acrylate monomer 2, a cross-linking agent, a photoinitiator and a surfactant to obtain an oil phase 2, and then adding the water phase C and the water phase D to obtain an HIPE emulsion 2; s3, coating cloth with the HIPE emulsion 1 and the HIPE emulsion 2, performing illumination and steam treatment, and then performing dehydration, drying and slitting to obtain the liquid sanitary towel absorption core body; wherein the surfactant is obtained by reacting acrylic amino alkyl ester with alkyl halide and/or alkyl halide derivatives. The liquid transfer capacity is improved, the product has the effects of efficient absorption and lasting dryness, the defects in the prior art are o
